Conference Coverage

LYON, France – Lerodalcibep, a novel, third-generation anti-proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, helps high-risk patients already receiving maximally tolerated statins to achieve guideline lipid targets, reported investigators.

In the randomized, placebo-controlled LIBerate-CVD trial of more than 900 patients, lerodalcibep led to reductions from baseline in low-density lipoprotein (LDL) cholesterol levels of more than 60%.

“We believe that lerodalcibep offers a novel, effective alternative to current PCSK9 inhibitors for patients with cardiovascular disease or at very high risk for cardiovascular disease,” said Evan Stein, MD, PhD, chief scientific officer and cofounder of LIB Therapeutics in Chicago, who presented the findings at the European Atherosclerosis Society (EAS) 2024.

Moreover, it leads to “substantial additional LDL cholesterol reductions on top of existing oral agents” and allows more than 90% of patients to achieve the latest European Society of Cardiology (ESC) guideline targets, he said.

Lerodalcibep has “tolerability and safety similar to placebo,” Dr. Stein said, and requires only “a small monthly injection, which takes about 12 seconds.”

“The drug doesn’t require refrigeration” and is “stable, so far, over 9 months,” he reported.

The latest data “confirm the efficacy of lerodalcibep,” said Giuseppe Danilo Norata, PhD, from the Department of Pharmacological and Biomolecular Sciences at the University of Milan, Milan, Italy, who was not involved in the study.

The LDL cholesterol reduction in this phase 3 trial is “in line with what was observed in LIBerate-FH,” and the high proportion of patients achieving their LDL cholesterol target is “impressive,” he added.
 

Effective and Well Tolerated

The safety results are “suggestive of a drug that is well tolerated, with injection-site reactions being the only remarkable adverse event increased in the treatment group,” Dr. Norata reported.

Only a “limited number” of patients developed neutralizing antidrug antibodies, which did not affect the efficacy of lerodalcibep. However, “given that the therapy is expected to be administered for years,” a longer analysis is needed to exclude the concern that a small percentage of neutralizing antidrug antibodies could reduce the efficacy, he said.

If approved, lerodalcibep could end up as a first-line option in the treatment pathway for high-risk cardiovascular disease because the efficacy “is similar to that of other injectable PCSK9 inhibitors,” he said, adding that its position in the market will “largely depend on the price.”

As the mechanism of action is similar to that of other monoclonal antibodies, “there is no pharmacological rationale to use it after another PSCK9 inhibitor,” he explained.

Lerodalcibep is a small recombinant fusion protein that combines a PCSK9-binding domain with human serum albumin.

The binding domain blocks the interaction between PCSK9 and the LDL cholesterol receptor, and the albumin linkage increases the half-life to 12-15 days, allowing low-volume injections to be given every 4 weeks.

A prior phase 2 study suggested that lerodalcibep substantially decreases LDL cholesterol levels in patients already taking maximally tolerated statins. The 300-mg dose was associated with an average reduction from baseline in LDL cholesterol levels of 77% over 12 weeks, whereas free PCSK9 levels decreased by 88%.

The current phase 3 study enrolled individuals at 65 centers in 100 countries who had or were at a very high risk for cardiovascular disease and who had an LDL cholesterol level of ≥ 1.8 mmol/L despite being on maximally tolerated statins.

Study participants were randomized in a 2:1 ratio to receive monthly subcutaneous lerodalcibep (n = 614) or placebo (n = 308) for 52 weeks and were assessed for the co-primary endpoints of the percentage change in LDL cholesterol levels from baseline to week 52 and the mean of levels at weeks 50 and 52.

The mean age was similar in the lerodalcibep and placebo groups (63.3 vs 64.5 years), as were the proportion of female (30% vs 30%) and White (80% vs 79%) participants.

The vast majority of participants in the lerodalcibep and placebo groups had a documented cardiovascular event (85.3% vs 86.4%) and were receiving secondary prevention, and 87% and 82%, respectively, were receiving a statin (any dose).

In a modified intention-to-treat analysis, the mean placebo-adjusted reduction in LDL cholesterol levels from baseline with lerodalcibep was 62% at week 52 (P < .0001), and the mean of levels at weeks 50 and 52 was 69.4% (P < .0001).

Similar results were seen in a per protocol analysis and an intention-to-treat analysis with imputation, which is a US Food and Drug Administration measure introduced in 2021 that assumes patients who discontinue the study treatment have an outcome similar to that in the placebo patients.

Moreover, 98.2% of patients in the lerodalcibep group achieved the ESC and European Atherosclerosis Society recommended reduction in LDL cholesterol levels of ≥ 50%, whereas only 8.8% in the placebo group did.
 

Hitting the LDL Cholesterol Target

More patients in the lerodalcibep group than in the placebo group achieved the LDL cholesterol target of < 1.4 mmol/L (95.3% vs 18.5%), and more patients in the lerodalcibep group achieved both that target and the ≥ 50% target (94.5% and 6.8%).

Lerodalcibep was also associated with significant reductions from baseline in levels of non–high-density lipoprotein (HDL) cholesterol, apolipoprotein B, very LDL cholesterol, and triglycerides, as well as an increase in HDL cholesterol levels (P < .0001 for all).

In terms of safety, lerodalcibep was associated with an adverse event rate leading to withdrawal similar to that seen with placebo (4.2% vs 3.6%), and 15.9% and 14.8% of patients, respectively, experienced at least one serious adverse event.

In-stent restenosis occurred more often in the lerodalcibep group than in the placebo group (5.4% vs 2.0%).

The study drug was associated with low levels of transient and sporadic antidrug antibodies and a low rate of neutralizing antidrug antibodies (0.9%), which were not associated with restenosis, a reduction in free PCSK9 levels, or the ability of lerodalcibep to lower LDL cholesterol levels.

CHICAGO — Surgical resection is the standard of care for small colorectal liver metastases, but the results of a phase 3 trial reported at the American Society of Clinical Oncology (ASCO) 2024 annual meeting may prompt a change.

At nearly 30 months of follow-up, European investigators found no difference in overall and progression-free survival with thermal ablation instead of surgery, as well as better local control, fewer adverse events, shorter hospital stays, and no treatment-related deaths.

The benefit of thermal ablation was so substantial that the trial was stopped early with about 300 of the planned 600 patients randomized.

Numerous retrospective studies have compared the two approaches, and some have reported better survival with surgery. As a result, although a large number of lesions are amenable to either approach, “the majority of colorectal liver mets [are] still being” resected, said lead investigator and presenter Martijn R. Meijerink, MD, PhD, an interventional radiologist at the Amsterdam University Medical Center, Amsterdam, the Netherlands.

Dr. Meijerink said many of the previous reviews were unreliable due to selection bias because patients only had ablation if their lesions couldn’t be removed surgically. In contrast, all patients in the COLLISION trial were eligible for resection.

“Thermal ablation in experienced centers seems to be at least as good as surgical resection for small liver tumors.” Patients would benefit if it replaced surgery as the standard of care with no compromise in survival, Dr. Meijerink added.

The 296 COLLISION patients were treated at 14 centers in the Netherlands, Belgium, and Italy. They had no more than 12 liver lesions 3 cm or smaller with a median of two lesions. Participants were split equally between the ablation and surgical arms of the trial.

Almost half of the surgeries were laparoscopic, and nearly 60% of the ablations were percutaneous. Recent technological advances were used in the ablation cases, including software to confirm the complete eradication of targeted metastases.

At 28.8 months, there was no difference in overall survival between treatment arms (hazard ratio [HR], 1.051; P = .813) and no difference in local (HR, 0.817; P = .53) and distant (HR, 1.03; P = .836) progression-free survival. Local control — meaning treated lesions didn’t grow back — favored thermal ablation (HR, 0.092; P = .024).

The results held across number subgroup analyses, including by stage, molecular profile, and number of lesions.

“Interestingly, the majority of ablation site recurrences were somehow retreated, and most of them successfully, [while] the majority of resection plane recurrences were not retreated,” Dr. Meijerink said.

Patients with ablation vs surgery spent a median of 1 day vs 4 days in the hospital. Almost 20% of patients in the surgery group had grade 3/4 treatment-related adverse events vs 6% of those in the ablation group, which isn’t surprising, Dr. Meijerink said, because “the needle is less invasive than a knife.”

Three patients (2.1%) died of surgical complications, but there were no treatment-related deaths with ablation.

Major Kenneth Lee, MD, PhD, a gastrointestinal surgeon at the University of Pennsylvania, Philadelphia, who was the study discussant, emphasized the importance of gathering prospective data to compare the two approaches fairly.

“Ablation appears equivalent to resection for small, ideally located colorectal liver mets,” he said. Still, longer follow-up is needed to ensure that cure rates with ablation match those with surgery.

The study was funded by Medtronic-Covidien, a maker of thermal ablation equipment. Among other industry ties, Dr. Meijerink reported receiving honoraria and research funding from Medtronic and advising the company. Dr. Lee didn’t have any disclosures.

MONTREAL – Levels of neurofilament light chain (Nfl) may be a biomarker of chemotherapy-induced peripheral neurotoxicity (CIPN), new research suggests.

Investigators found Nfl levels increased in cancer patients following a first infusion of the medication paclitaxel and corresponded to neuropathy severity 6-12 months post-treatment, suggesting the blood protein may provide an early CIPN biomarker.

“Nfl after a single cycle could detect axonal degeneration,” said lead investigator Masarra Joda, a researcher and PhD candidate at the University of Sydney in Australia. She added that “quantification of Nfl may provide a clinically useful marker of emerging neurotoxicity in patients vulnerable to CIPN.”

The findings were presented at the Peripheral Nerve Society (PNS) 2024 annual meeting.
 

Common, Burdensome Side Effect

A common side effect of chemotherapy, CIPN manifests as sensory neuropathy and causes degeneration of the peripheral axons. A protein biomarker of axonal degeneration, Nfl has previously been investigated as a way of identifying patients at risk of CIPN.

The goal of the current study was to identify the potential link between Nfl with neurophysiological markers of axon degeneration in patients receiving the neurotoxin chemotherapy paclitaxel.

The study included 93 cancer patients. All were assessed at the beginning, middle, and end of treatment. CIPN was assessed using blood samples of Nfl and the Total Neuropathy Score (TNS), the Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale, and patient-reported measures using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Chemotherapy-Induced Peripheral Neuropathy Module (EORTC-CIPN20).

Axonal degeneration was measured with neurophysiological tests including sural nerve compound sensory action potential (CSAP) for the lower limbs, and sensory median nerve CSAP, as well as stimulus threshold testing, for the upper limbs. 

Almost all of study participants (97%) were female. The majority (66%) had breast cancer and 30% had gynecological cancer. Most (73%) were receiving a weekly regimen of paclitaxel, and the remainder were treated with taxanes plus platinum once every 3 weeks. By the end of treatment, 82% of the patients had developed CIPN, which was mild in 44% and moderate/severe in 38%. 

Nfl levels increased significantly from baseline to after the first dose of chemotherapy (P < .001), “highlighting that nerve damage occurs from the very beginning of treatment,” senior investigator Susanna Park, PhD, told this news organization. 

In addition, “patients with higher Nfl levels after a single paclitaxel treatment had greater neuropathy at the end of treatment (higher EORTC scores [P ≤ .026], and higher TNS scores [P ≤ .00]),” added Dr. Park, who is associate professor at the University of Sydney.

“Importantly, we also looked at long-term outcomes beyond the end of chemotherapy, because chronic neuropathy produces a significant burden in cancer survivors,” said Dr. Park. 

“Among a total of 44 patients who completed the 6- to 12-month post-treatment follow-up, NfL levels after a single treatment were linked to severity of nerve damage quantified with neurophysiological tests, and greater Nfl levels at mid-treatment were correlated with worse patient and neurologically graded neuropathy at 6-12 months.”

Dr. Park said the results suggest that NfL may provide a biomarker of long-term axon damage and that Nfl assays “may enable clinicians to evaluate the risk of long-term toxicity early during paclitaxel treatment to hopefully provide clinically significant information to guide better treatment titration.” 

Currently, she said, CIPN is a prominent cause of dose reduction and early chemotherapy cessation. 

“For example, in early breast cancer around 25% of patients experience a dose reduction due to the severity of neuropathy symptoms.” But, she said, “there is no standardized way of identifying which patients are at risk of long-term neuropathy and therefore, may benefit more from dose reduction. In this setting, a biomarker such as Nfl could provide oncologists with more information about the risk of long-term toxicity and take that into account in dose decision-making.” 

For some cancers, she added, there are multiple potential therapy options.

“A biomarker such as NfL could assist in determining risk-benefit profile in terms of switching to alternate therapies. However, further studies will be needed to fully define the utility of NfL as a biomarker of paclitaxel neuropathy.” 
 

Promising Research

Commenting on the research for this news organization, Maryam Lustberg, MD, associate professor, director of the Center for Breast Cancer at Smilow Cancer Hospital and Yale Cancer Center, and chief of Breast Medical Oncology at Yale Cancer Center, in New Haven, Connecticut, said the study “builds on a body of work previously reported by others showing that neurofilament light chains as detected in the blood can be associated with early signs of neurotoxic injury.” 

She added that the research “is promising, since existing clinical and patient-reported measures tend to under-detect chemotherapy-induced neuropathy until more permanent injury might have occurred.” 

Dr. Lustberg, who is immediate past president of the Multinational Association of Supportive Care in Cancer, said future studies are needed before Nfl testing can be implemented in routine practice, but that “early detection will allow earlier initiation of supportive care strategies such as physical therapy and exercise, as well as dose modifications, which may be helpful for preventing permanent damage and improving quality of life.” 

The investigators and Dr. Lustberg report no relevant financial relationships.

MONTREAL – Levels of neurofilament light chain (Nfl) may be a biomarker of chemotherapy-induced peripheral neurotoxicity (CIPN), new research suggests.

Investigators found Nfl levels increased in cancer patients following a first infusion of the medication paclitaxel and corresponded to neuropathy severity 6-12 months post-treatment, suggesting the blood protein may provide an early CIPN biomarker.

“Nfl after a single cycle could detect axonal degeneration,” said lead investigator Masarra Joda, a researcher and PhD candidate at the University of Sydney in Australia. She added that “quantification of Nfl may provide a clinically useful marker of emerging neurotoxicity in patients vulnerable to CIPN.”

The findings were presented at the Peripheral Nerve Society (PNS) 2024 annual meeting.
 

Common, Burdensome Side Effect

A common side effect of chemotherapy, CIPN manifests as sensory neuropathy and causes degeneration of the peripheral axons. A protein biomarker of axonal degeneration, Nfl has previously been investigated as a way of identifying patients at risk of CIPN.

The goal of the current study was to identify the potential link between Nfl with neurophysiological markers of axon degeneration in patients receiving the neurotoxin chemotherapy paclitaxel.

The study included 93 cancer patients. All were assessed at the beginning, middle, and end of treatment. CIPN was assessed using blood samples of Nfl and the Total Neuropathy Score (TNS), the Common Terminology Criteria for Adverse Events (CTCAE) neuropathy scale, and patient-reported measures using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Chemotherapy-Induced Peripheral Neuropathy Module (EORTC-CIPN20).

Axonal degeneration was measured with neurophysiological tests including sural nerve compound sensory action potential (CSAP) for the lower limbs, and sensory median nerve CSAP, as well as stimulus threshold testing, for the upper limbs. 

Almost all of study participants (97%) were female. The majority (66%) had breast cancer and 30% had gynecological cancer. Most (73%) were receiving a weekly regimen of paclitaxel, and the remainder were treated with taxanes plus platinum once every 3 weeks. By the end of treatment, 82% of the patients had developed CIPN, which was mild in 44% and moderate/severe in 38%. 

Nfl levels increased significantly from baseline to after the first dose of chemotherapy (P < .001), “highlighting that nerve damage occurs from the very beginning of treatment,” senior investigator Susanna Park, PhD, told this news organization. 

In addition, “patients with higher Nfl levels after a single paclitaxel treatment had greater neuropathy at the end of treatment (higher EORTC scores [P ≤ .026], and higher TNS scores [P ≤ .00]),” added Dr. Park, who is associate professor at the University of Sydney.

“Importantly, we also looked at long-term outcomes beyond the end of chemotherapy, because chronic neuropathy produces a significant burden in cancer survivors,” said Dr. Park. 

“Among a total of 44 patients who completed the 6- to 12-month post-treatment follow-up, NfL levels after a single treatment were linked to severity of nerve damage quantified with neurophysiological tests, and greater Nfl levels at mid-treatment were correlated with worse patient and neurologically graded neuropathy at 6-12 months.”

A central aim of prostate cancer treatment is to prolong survival, but trials often overlook another key goal: Improving — or at least maintaining — quality of life (QoL).

The recent American Society of Clinical Oncology (ASCO) 2024 annual meeting dedicated a session to QoL outcomes in men with prostate cancer.

The trials explored the effects of treatment suspension or intensification on health-related QoL as well as interventions to manage side effects in different patient populations.

The first presentation focused on a post hoc analysis of the phase 3 EMBARK trial, which looked at the effect of suspending treatment on health-related QoL in men with nonmetastatic disease at a high risk for biochemical recurrence.

Earlier findings from the trial, presented at ESMO in 2023, showed enzalutamide alone or in combination with androgen deprivation therapy (ADT) was associated with a significant improvement in metastasis-free survival vs placebo plus leuprolide.

The initial trial randomized 1068 patients at a high risk for biochemical recurrence to these three treatment groups and suspended therapy at week 37 if prostate-specific antigen (PSA) levels fell below 0.2 ng/mL. Patients, however, were not randomized into the treatment suspension groups. Treatment resumed if PSA levels rose to ≥ 2.0 ng/mL in patients who had undergone radical prostatectomy or ≥ 5.0 ng/mL in those who had not had surgery.

The post hoc analysis, which assessed patient-reported QoL outcomes following treatment suspension at baseline and every 12 weeks until progression, found no meaningful changes in the worst pain in the past 24 hours, as measured by the Brief Pain Inventory–Short Form.

Patients also reported no meaningful changes in total and physical well-being scores on the Functional Assessment of Cancer Therapy–Prostate (FACT-P) and on the European Quality of Life Five-Dimensions (EuroQol-5D) visual analog scale score, as well as no meaningful changes in sexual activity and urinary and bowel symptoms, based on scores from the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire–Prostate 25 (QLQ-PR25).

Hormone treatment-related symptoms on the QLQ-PR25, however, “quickly improved but eventually began to worsen after week 97,” explained lead author Stephen J. Freedland, MD, from Cedars-Sinai Medical Center, Los Angeles, California, who presented the new findings at ASCO.

Dr. Freedland concluded that the EMBARK results show that enzalutamide, with or without ADT, improves metastasis-free survival vs leuprolide alone, without affecting global health-related QoL during treatment or after treatment suspension.

However, Channing J. Paller, MD, of the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins Medicine, Baltimore, Maryland, who was not involved in the research, pointed out that “patient selection is key” when choosing therapies, given that ADT has distinct adverse effects. Comorbidities and adverse effects “must be taken into consideration to help the doctor and patient make more personalized treatment choices.”
 

Treatment Intensification and QoL

Another presentation explored health-related QoL outcomes from the phase 3 PRESTO trial.

The study examined ADT intensification in 504 patients who had high-risk biochemically relapsed nonmetastatic hormone-sensitive prostate cancer and a PSA doubling time of 9 months or less. Patients were randomized to ADT monotherapy with degarelix or leuprolide, ADT plus apalutamide, or ADT plus apalutamide, abiraterone acetate, and prednisone.

In previous data from PRESTO, the combination therapy groups both had significantly longer median PSA progression-free survival than the ADT monotherapy arm.

The latest data looked at the health-related QoL outcomes in the PRESTO population, measured using the Expanded Prostate Cancer Index Composite, the PROMIS Fatigue tool, the Hot Flash Related Daily Interference Scale, and the EuroQol-5D.

Ronald C. Chen, MD, MPH, of the University of Kansas Medical Center, Kansas City, who presented the new findings at ASCO, reported that ADT plus apalutamide improved PSA progression-free survival over ADT alone and did not meaningfully increase common treatment-related symptoms, such as hormonal symptoms, sexual dysfunction, hot flash interference, and fatigue.

However, treatment intensification with triple androgen regimen did not lead to further improvements in PSA progression-free survival but did increase the rate of serious adverse events, the time to testosterone recover, and increased hot flash interference.

PRESTO as well as EMBARK “provide a strong rationale for intensification of androgen blockade in men with high-risk biochemical recurrence after completing primary local therapy” and could even “reduce the need for subsequent treatment,” concluded Dr. Chen.
 

CBT for Managing ADT Side Effects

Up to 80% of men receiving ADT to treat prostate cancer experience night sweats and hot flashes, which are associated with sleep disturbance, anxiety, low mood, and cognitive impairments.

A third trial presented during the session looked at the impact of cognitive-behavioral therapy (CBT) on these side effects of ADT treatment.

Initial findings from the MANCAN study found that CBT delivered by a psychologist reduced the impact of hot flashes and night sweats at 6 weeks.

The MANCAN2 study assessed QoL at 6 months among 162 patients with localized or advanced prostate cancer who underwent at least 6 months of continuous ADT and who experienced more severe hot flashes and night sweats, defined as a score of ≥ 2 on the hot flashes and night sweats problem rating scale.

Study participants were randomized to CBT plus treatment as usual, or treatment as usual alone, with the intervention consisting of two CBT group sessions 4 weeks apart. Between CBT sessions, patients could refer to a booklet and CD, alongside exercises and CBT strategies.

MANCAN2 confirmed that CBT was associated with a significantly greater reduction in hot flash and night sweat scores over standard care alone at 6 weeks. Patients receiving CBT also reported better QoL, sleep, and functional status but those differences did not reach statistical significance.

By 6 months, those in the CBT group still reported better outcomes in each category, but no differences were statistically significant at this time point. Overall, however, 14% of treatment as usual alone patients discontinued ADT at 6 months vs none in the CBT arm.

“Further research is therefore needed to determine whether or not you can make this effect more durable” and to look at “the potential for CBT to support treatment compliance,” said study presenter Simon J. Crabb, PhD, MBBS, from the University of Southampton and University Hospital Southampton NHS Foundation Trust, Southampton, England.
 

QoL With Radioligand Crossover

Finally, the phase 3 PSMAfore study compared ¹⁷⁷Lu-PSMA-617 with abiraterone or enzalutamide in 468 taxane-naive patients with metastatic castration-resistant prostate cancer who had progressed on a previous androgen receptor pathway inhibitor.

In earlier analyses, Karim Fizazi, MD, PhD, Institut Gustave Roussy, Université Paris-Saclay, Paris, France, reported that ¹⁷⁷Lu-PSMA-617 improved radiographic progression-free survival by 59% over androgen receptor pathway inhibitor therapy but did not lead to significant differences in overall survival.

In a new interim analysis, Dr. Fizazi and colleagues explored outcomes in patients eligible to cross over to ¹⁷⁷Lu-PSMA-617 following androgen receptor pathway inhibitor therapy. Assessments of health-related QoL revealed that ¹⁷⁷Lu-PSMA-617 led to about a 40% improvement in scores on two QoL tools — 41% with FACT-P and 39% with EuroQol-5D.

On subscales of FACT-P, Dr. Fizazi reported that ¹⁷⁷Lu-PSMA-617 was also associated with a significantly longer time to worsening in physical, functional, and emotional well-being over standard therapy. A pain inventory score indicated that ¹⁷⁷Lu-PSMA-617 led to a 31% improvement in the time to worsening pain intensity, as well as a 33% increase in the time to worsening pain interference.

With the treatment having a “favorable safety profile,” Dr. Fizazi said the results suggest ¹⁷⁷Lu-PSMA-617 is a “treatment option” for patients with metastatic castration-resistant prostate cancer who have undergone androgen receptor pathway inhibitor treatment.

MANCAN2 was funded by the UK National Institute for Health and Care Research. EMBARK was funded by Astellas Pharma and Pfizer, the codevelopers of enzalutamide. PRESTO was funded by Alliance Foundation Trials and Johnson & Johnson. PSMAfore was funded by Novartis. Dr. Freedland declared relationships with Pfizer and Astellas Pharma, among others. Paller declared relationships with AstraZeneca, Dendreon, Exelixis, Janssen Oncology, Omnitura, Lilly, and Bayer. Dr. Chen declared relationships with Astellas Pharma, Pfizer, and others. Dr. Crabb declared relationships with AstraZeneca, Bristol-Myers Squibb, Ipsen, Merck, Amgen, Amphista Therapeutics, Bayer, Janssen, MSD, Pfizer, Astex Pharmaceuticals, Clovis Oncology, and Roche. Dr. Fizazi reported relationships with Novartis, AstraZeneca, and a dozen other companies.

However, treatment intensification with triple androgen regimen did not lead to further improvements in PSA progression-free survival but did increase the rate of serious adverse events, the time to testosterone recover, and increased hot flash interference.

PRESTO as well as EMBARK “provide a strong rationale for intensification of androgen blockade in men with high-risk biochemical recurrence after completing primary local therapy” and could even “reduce the need for subsequent treatment,” concluded Dr. Chen.
 

CBT for Managing ADT Side Effects

Up to 80% of men receiving ADT to treat prostate cancer experience night sweats and hot flashes, which are associated with sleep disturbance, anxiety, low mood, and cognitive impairments.

A third trial presented during the session looked at the impact of cognitive-behavioral therapy (CBT) on these side effects of ADT treatment.

Initial findings from the MANCAN study found that CBT delivered by a psychologist reduced the impact of hot flashes and night sweats at 6 weeks.

The MANCAN2 study assessed QoL at 6 months among 162 patients with localized or advanced prostate cancer who underwent at least 6 months of continuous ADT and who experienced more severe hot flashes and night sweats, defined as a score of ≥ 2 on the hot flashes and night sweats problem rating scale.

Study participants were randomized to CBT plus treatment as usual, or treatment as usual alone, with the intervention consisting of two CBT group sessions 4 weeks apart. Between CBT sessions, patients could refer to a booklet and CD, alongside exercises and CBT strategies.

MANCAN2 confirmed that CBT was associated with a significantly greater reduction in hot flash and night sweat scores over standard care alone at 6 weeks. Patients receiving CBT also reported better QoL, sleep, and functional status but those differences did not reach statistical significance.

By 6 months, those in the CBT group still reported better outcomes in each category, but no differences were statistically significant at this time point. Overall, however, 14% of treatment as usual alone patients discontinued ADT at 6 months vs none in the CBT arm.

“Further research is therefore needed to determine whether or not you can make this effect more durable” and to look at “the potential for CBT to support treatment compliance,” said study presenter Simon J. Crabb, PhD, MBBS, from the University of Southampton and University Hospital Southampton NHS Foundation Trust, Southampton, England.
 

QoL With Radioligand Crossover

Finally, the phase 3 PSMAfore study compared ¹⁷⁷Lu-PSMA-617 with abiraterone or enzalutamide in 468 taxane-naive patients with metastatic castration-resistant prostate cancer who had progressed on a previous androgen receptor pathway inhibitor.

In earlier analyses, Karim Fizazi, MD, PhD, Institut Gustave Roussy, Université Paris-Saclay, Paris, France, reported that ¹⁷⁷Lu-PSMA-617 improved radiographic progression-free survival by 59% over androgen receptor pathway inhibitor therapy but did not lead to significant differences in overall survival.

In a new interim analysis, Dr. Fizazi and colleagues explored outcomes in patients eligible to cross over to ¹⁷⁷Lu-PSMA-617 following androgen receptor pathway inhibitor therapy. Assessments of health-related QoL revealed that ¹⁷⁷Lu-PSMA-617 led to about a 40% improvement in scores on two QoL tools — 41% with FACT-P and 39% with EuroQol-5D.

On subscales of FACT-P, Dr. Fizazi reported that ¹⁷⁷Lu-PSMA-617 was also associated with a significantly longer time to worsening in physical, functional, and emotional well-being over standard therapy. A pain inventory score indicated that ¹⁷⁷Lu-PSMA-617 led to a 31% improvement in the time to worsening pain intensity, as well as a 33% increase in the time to worsening pain interference.

With the treatment having a “favorable safety profile,” Dr. Fizazi said the results suggest ¹⁷⁷Lu-PSMA-617 is a “treatment option” for patients with metastatic castration-resistant prostate cancer who have undergone androgen receptor pathway inhibitor treatment.

MANCAN2 was funded by the UK National Institute for Health and Care Research. EMBARK was funded by Astellas Pharma and Pfizer, the codevelopers of enzalutamide. PRESTO was funded by Alliance Foundation Trials and Johnson & Johnson. PSMAfore was funded by Novartis. Dr. Freedland declared relationships with Pfizer and Astellas Pharma, among others. Paller declared relationships with AstraZeneca, Dendreon, Exelixis, Janssen Oncology, Omnitura, Lilly, and Bayer. Dr. Chen declared relationships with Astellas Pharma, Pfizer, and others. Dr. Crabb declared relationships with AstraZeneca, Bristol-Myers Squibb, Ipsen, Merck, Amgen, Amphista Therapeutics, Bayer, Janssen, MSD, Pfizer, Astex Pharmaceuticals, Clovis Oncology, and Roche. Dr. Fizazi reported relationships with Novartis, AstraZeneca, and a dozen other companies.

Not too long ago, prostate-cancer genetics didn’t mean much to patient care. But in recent years, the landscape of therapy has transformed as researchers have discovered links between multiple genes and aggressive tumors. 

Now, as a hematologist-oncologist explained to attendees at an Association of VA Hematology/Oncology regional meeting in Detroit, genetic tests can guide treatment for some—but not all—men with prostate cancer.

For patients with mutations, appropriate supplemental medications “can improve overall outcomes and have a long-standing impact on patients” said Scott J. Dawsey, MD, of the John D. Dingell Veterans Affairs Medical Center in Detroit in an interview following the AVAHO meeting, which focused on the management of prostate cancer.

As Dawsey explained, about 10% of patients with prostate cancer appear to have genetic mutations, although the exact percentage is unclear. The mutations are especially common in metastatic forms of prostate cancer. They’re estimated to be present in 11.8%-16.2% of those cases.

While these proportions are relatively small, the number of overall prostate-cancer cases with mutations is large due to the high burden of the disease, Dawsey said. Prostate cancer is by far the most common cancer in men, and estimated 299,010 cases will be diagnosed in the United States this year.

According to Dawsey, genetic mutations seem to boost the risk of more aggressive disease—and the risk of other malignancies—by disrupting DNA repair. This process can lead to even more mutations that may “make the cancer behave and grow more aggressively.”

But not all prostate cancer patients need to undergo genetic testing. Dawsey urged colleagues to figure out which patients should be tested by consulting National Comprehensive Cancer Network (NCCN) guidelines and the newly updated US Department of Veterans Affairs (VA) prostate cancer clinical pathway.

The two sets of recommendations agree on germline testing in patients with cases that are metastatic, very high risk, and high risk. Lower-risk cases should only be tested if patients meet family history criteria. The sets of guidelines also recommend somatic testing in patients with metastatic cancer.

In addition to providing guidance about treatment, genetic test results can have implications regarding other potential malignancies that may affect patients, Dawsey said. The results may also have implications for cancer risk in family members.

Several drugs are now available for patients with genetic mutations, including checkpoint inhibitors and PARP inhibitors. The drugs, which have unique mechanisms of action, are given in addition to standard prostate cancer treatments, he said.

“If a patient doesn’t have one of these genetic changes,” he said, “these drugs aren’t an option.”

A long list of drugs or combinations of drugs are in clinical trials, including the poly(adenosine diphosphate–ribose) polymerase (PARP) inhibitors olaparib, abiraterone, and niraparib and the checkpoint inhibitors nivolumab and cemiplimab.

The drugs generally improve response rates and progression-free survival, Dawsey said, and patients are generally able to tolerate them. In regard to which drugs to choose, he suggested consulting the and NCCN guidelines and the VA oncology clinical pathway for prostate cancer.

Findings from the phase 3 ESOPEC trial demonstrate an overall survival advantage with a perioperative chemotherapy regimen known as FLOT, compared with a neoadjuvant chemoradiation approach, called CROSS, in patients with resectable, locally advanced esophageal adenocarcinoma.

The study results, presented as a late-breaking abstract at the annual meeting of the American Society of Clinical Oncology (ASCO), help settle a long-standing debate about whether chemotherapy with FLOT — 5-florouracil, leucovorin, oxaliplatin, and docetaxel — before and after surgery, or neoadjuvant radiation plus CROSS — carboplatin and paclitaxel — followed by surgery is the best approach.

There has been “considerable disagreement as to whether giving all adjuvant therapy upfront versus ‘sandwich’ adjuvant therapy before and after surgery is the better standard of care for locally advanced resectable esophageal cancer,” Jennifer Tseng, MD, of Boston Medical Center, Boston, said in an ASCO press release. This randomized clinical trial shows the sandwich approach “provides better outcomes.”

The practice-changing ESOPEC findings will have an important effect on the management of patients with resectable esophageal adenocarcinoma and gastroesophageal junction adenocarcinoma, but local and distant failures remain a challenge in this population, explained invited discussant Karyn A. Goodman, MD.

Advances since the initiation of ESOPEC — such as immunotherapy options and personalized strategies — suggest the esophageal adenocarcinoma story is still evolving, said Dr. Goodman, professor and vice chair of research and quality in the Department of Radiation Oncology at Icahn School of Medicine at Mount Sinai, New York. 
 

The ESOPEC trial

Both the FLOT and CROSS regimens are established standards of care in resectable esophageal adenocarcinoma, and the choice of treatment has largely varied based on geographical location.

The current randomized, prospective, open-label ESOPEC trial, however, demonstrated that FLOT can prolong overall survival, first author Jens Hoeppner, MD, from the University of Bielefeld in Detmold, Germany, reported.

Overall, 438 patients with locally advanced, resectable esophageal adenocarcinoma recruited between February 2016 and April 2020 from 25 sites in Germany and randomized to either FLOT (n = 221) or CROSS (n = 217). The median age was 63 years, and most (89.3%) were men. Patients were followed until November 2023, and median follow-up was 55 months.

Patients in the FLOT arm received four cycles — one every 2 weeks for 8 weeks — followed by surgery 4-6 weeks later. FLOT cycles were reinitiated 4-6 weeks after surgery and given every 2 weeks for 8 weeks.

Those in the CROSS arm received one cycle per week of radiation therapy for 5 weeks plus carboplatin and paclitaxel followed by surgery 4-6 weeks after the last cycle.

Overall, 86% received both neoadjuvant therapy and surgery in the FLOT arm versus 82.9% in the CROSS group. Among these patients, 16.8% in the FLOT group achieved a pathological complete remission versus 10.0% in the CROSS arm.

In the intention-to-treat population, median overall survival was almost twice as long in the FLOT group — 66 months versus 37 months. At 3 years, those who received FLOT had a 30% lower risk of dying (hazard ratio [HR], 0.70), with 57.4% of patients alive at that point, compared with 50.7% patients in the CROSS arm.

The 5-year overall survival was 50.6% in the FLOT group versus 38.7% in the CROSS group.

Patients receiving FLOT also demonstrated improved progression-free survival (PFS), with a median PFS of 38 months versus 16 months. The 3-year PFS was 51.6% with FLOT versus 35.0% with CROSS (HR, 0.66). The exploratory subgroup analyses for sex, age, ECOG status, and clinical T and N stages also favored FLOT.

The 30-day postoperative mortality was 1.0% in the FLOT group and 1.7% in the CROSS group, and the 90-day postoperative mortality rate was 3.2% and 5.6%, respectively.

Based on these findings, perioperative chemotherapy with FLOT should be preferred over neoadjuvant chemoradiation with CROSS, Dr. Hoeppner concluded.

Dr. Goodman agreed, noting that, in the wake of ESOPEC, FLOT will likely be adopted as a more standard approach in the United States for patients who are fit. And, for patients who are not candidates for FLOT, CROSS is a reasonable option, she said.

But, she asked, does it really have to be an either/or situation?

Multiple studies, including Dr. Goodman’s 2021 Alliance/CALGB 80803 study, have demonstrated promising outcomes with combined modalities and adapting therapy based on treatment response. Several trials, for instance, are evaluating combining FLOT and CROSS, with some showing the approach is feasible and comes with manageable toxicity.

It’s also important to look outside of FLOT and CROSS. During ESOPEC, new approaches entered the treatment landscape, including the use of adjuvant immunotherapy following neoadjuvant chemoradiation and surgery for noncomplete response.

Take the CheckMate 577 study, which found that adjuvant nivolumab immunotherapy after preoperative CROSS and surgery significantly reduced metastatic recurrence and doubled disease-free survival in patients who did not achieve a complete response. This approach is now a standard of care for those patients.

FLOT plus neoadjuvant nivolumab may also be a viable option, Dr. Goodman noted, but we haven’t yet seen “any benefit in survival with the combo of chemotherapy and immunotherapy for resectable esophago-gastric cancer.”

Further studies are needed to evaluate the synergy of immunotherapy and radiotherapy. The next chapter of the esophageal adenocarcinoma story may feature a “best-of-both-worlds” approach that combines induction chemotherapy, followed by personalized chemoradiation, surgery, and potentially adjuvant immunotherapy, Dr. Goodman explained.

While the ESOPEC findings are impressive, the 5-year overall survival of only 50% is still suboptimal, she noted. “Given the poor prognosis with this disease, we need to continue to develop clinical trials to identify better targets, novel treatment combinations, and select patients that will respond best to specific treatment.”

ESOPEC was funded by the Deutsche Forschungsgemeinschaft (German Research Foundation). Dr. Hoeppner reported receiving travel, accommodations, and expenses from Intuitive Surgical. Dr. Goodman reported a relationship with the National Cancer Institute and consulting or advisory roles for Novartis, Philips Healthcare, RenovoRX, and Roche/Genentech.

VIENNA – The use of immunosuppressive and antifibrotic drugs to treat skin and lung fibrosis leads updated recommendations from the European Alliance of Associations for Rheumatology (EULAR) for the treatment of systemic sclerosis.

“The most impactful new recommendation relates to the evidence for immunosuppressive agents and antifibrotics for the treatment of skin fibrosis and lung fibrosis,” said Francesco Del Galdo, MD, PhD, professor of experimental medicine, consultant rheumatologist, and scleroderma and connective tissue diseases specialist at Leeds Teaching Hospitals NHS Trust, Leeds, England. Dr. Del Galdo presented the update at the annual European Congress of Rheumatology.

“But there are also new recommendations, including a redefined target population for hematopoietic stem cell transplantation following cyclophosphamide, the upfront combination treatment at the time of diagnosis of pulmonary arterial hypertension [PAH], and a negative recommendation for the use of anticoagulants for pulmonary arterial hypertension,” noted Dr. Del Galdo, highlighting key updates in the 2024 recommendations.

Landewé, MD, PhD, professor and rheumatologist at Amsterdam University Medical Center, Amsterdam, the Netherlands, and Zuyderland Medical Center, Heerlen, the Netherlands, co-moderated the session on EULAR recommendations. “The management of systemic sclerosis is a field in which a lot is happening,” he said. “The last update goes back to 2017, and in the meantime, many new approaches have seen the light, especially pertaining to skin fibrosis and interstitial lung disease. Six new recommendations have been coined, covering drugs like mycophenolate mofetil, nintedanib, rituximab, and tocilizumab. None of these therapies were present in the 2017 recommendations. It seems the field is now ready to further expand on targeted therapies for the management of musculoskeletal and gastrointestinal manifestations, calcinosis, and the local management of digital ulcers.”
 

‘Therapeutic Continuums’ Aid Disease Management

Dr. Del Galdo and his colleagues grouped the various interventions across what the recommendations label as evidence-backed “therapeutic continuums.” These span six of the eight different clinical manifestations of systemic sclerosis: Raynaud’s phenomenon, digital ulcers, pulmonary hypertension, musculoskeletal manifestations, skin fibrosis, interstitial lung disease (ILD), and gastrointestinal and renal crisis.

A slide showing the different strengths of evidence for various drugs across the eight manifestations illustrated the principle behind the therapeutic continuums. “These ‘therapeutic continuums’ suggest a common pathogenetic mechanism driving the various manifestations of disease,” said Dr. Del Galdo. For example, he noted, “If rituximab had a positive response in skin and in lung, it suggests that B cells play a role in the clinical manifestations of skin and lung in this disease.”

Dr. Del Galdo highlighted the new immunosuppression continuum and associated treatments for skin and lung fibrosis. “For skin involvement, the task force recommended mycophenolate, methotrexate, and rituximab, with tocilizumab having a lower level of evidence and lower recommendation strength; similarly, in interstitial lung disease, we have rituximab, mycophenolate, cyclophosphamide, and nintedanib, and these all have the highest strength of evidence. Tocilizumab is assigned one strength of evidence below the other drugs.”

He also cited the phosphodiesterase 5 inhibitor (PDE5i) drugs that are used across Raynaud’s phenomenon, digital ulcers, and pulmonary arterial hypertension, which together form a vascular therapeutic continuum.

The complexity of systemic sclerosis and multiple manifestations was a major determinant of the recommendations, Dr. Del Galdo pointed out. “The task force realized that since this is such a complex disease, we cannot recommend one treatment unconditionally. For example, with mycophenolate mofetil, what works for most patients for the skin and lung manifestations might not for someone who experiences severe diarrhea, in which mycophenolate is contraindicated. So, the highest degree of recommendation that the task force felt comfortable with was ‘should be considered.’ ”

Dr. Del Galdo stressed that the complex nature of systemic sclerosis means that “when thinking of treating one manifestation, you also always need to consider all the other clinical manifestations as experienced by the patient, and it is this multifaceted scenario that will ultimately lead to your final choice.”

Turning to new evidence around drug use, Dr. Del Galdo said that rituximab has the highest level of evidence across skin and lung manifestations, nintedanib is new in lung, and tocilizumab is new across both skin and lung.

To treat systemic sclerosis–pulmonary arterial hypertension (SSc-PAH), as long as there are no contraindications, the task force recommends using PDE5i and endothelin receptor antagonists (ERAs) at diagnosis. Data from phase 3 trials show a better outcome when the combination is established early.

The task force suggests avoiding the use of warfarin in PAH. “This is supported by a signal from two trials showing an increase in morbidity and mortality in these patients,” noted Dr. Del Galdo.

He also pointed out that selexipag and riociguat were new and important second-line additions for the treatment of PAH, and — consistent with the ERA approach — the EULAR recommendation supports frequent follow-up to establish a treat-to-target approach to maximizing clinical outcomes in SSc-PAH and SSc-ILD. “Specifically, for the first time, we recommend monitoring the effect of any chosen intervention selected within 3-6 months of starting. The evidence suggests there is a group of patients who respond and some who respond less well and who might benefit from a second-line intervention.”

For example, results of one trial support the approach of adding an antifibrotic agent to reduce progression in people with progressive lung fibrosis. “Similarly, for pulmonary hypertension, we recommend putting patients on dual treatment, and if this fails, place them on selexipag or switch the PDE5i to riociguat,” Dr. Del Galdo said.
 

Systemic Sclerosis Research Agenda and Recommendations Align

Dr. Del Galdo highlighted the value of therapeutic continuums in advancing disease understanding. “It is starting to teach us what we know and what we don’t and where do we need to build more evidence. Effectively, they determine where the gaps in therapy lie, and this starts to guide the research agenda.

“In fact, what is really interesting about this recommendation update — certainly from the perspective of disease understanding — is that we are starting to have a bird’s-eye view of the clinical manifestations of scleroderma that have so often been dealt with separately. Now we are starting to build a cumulative evidence map of this disease.”

In 2017, the research agenda largely advocated identifying immune-targeting drugs for skin and lung fibrosis, Dr. Del Galdo pointed out. “Now, we’ve done that — we’ve identified appropriate immunosuppressive drugs — and this is testimony to the importance of these recommendations because what prioritized the research agenda 10 years ago ended up informing the clinical trials and made it into the recommendations.”

“We definitely are one step forward compared to this 2017 recommendation and closer to what we would like to do,” he asserted.
 

Remission Elusive but Getting Closer

In some respects, according to Dr. Del Galdo, research and development is making relatively slow progress, especially compared with other rheumatologic diseases such as rheumatoid arthritis. “We cannot put patients with systemic sclerosis in remission yet. But I think we are one step ahead in that we’ve now established the treat-to-target approach to maximize the efficacy with which we can stall disease progression, but we cannot yet put these patients into remission,” he said. Systemic sclerosis has multiple manifestations, and fibrotic damage cannot be reversed. “Right now, the scar will remain there forever,” he noted.

Until remission is achievable, Dr. Del Galdo advises diagnosing and treating patients earlier to prevent fibrotic manifestations.

Dr. Del Galdo explained the three leading priorities on the systemic sclerosis research agenda. “There are three because it is such a complex disease. The first is considering the patient voice — this is the most important one, and the patients say they want a more holistic approach — so trialing and treating multiple manifestations together.”

Second, Dr. Del Galdo said, he would like to see a patient-reported measure developed that can capture the entire disease.

Third, from a physician’s point of view, Dr. Del Galdo said, “We want to send the patients into remission. We need to continue to further deconvolute the clinical manifestations and find the bottleneck at the beginning of the natural history of disease.

“If we can find a drug that is effective very early on, before the patients start getting the eight different manifestations with different levels of severity, then we will be on the right road, which we hope will end in remission.”

Dr. Del Galdo has served on the speakers bureau for AstraZeneca and Janssen; consulted for AstraZeneca, Boehringer Ingelheim, Capella, Chemomab, Janssen, and Mitsubishi-Tanabe; and received grant or research support from AbbVie, AstraZeneca, Boheringer Ingelheim, Capella, Chemomab, Kymab, Janssen, and Mitsubishi-Tanabe. Dr. Landewé had no relevant disclosures.

VIENNA — The interleukin-1 receptor antagonist (IL-1RA) canakinumab provided control of systemic juvenile idiopathic arthritis (sJIA) without the use of glucocorticoids for up to a year in most study participants after three monthly injections.

In this study of 20 patients with newly diagnosed sJIA treated off glucocorticoids, fever was controlled after a single injection in all patients, and 16 patients reached the primary outcome of remission after three injections, said Gerd Horneff, MD, PhD, Asklepios Children’s Hospital, Sankt Augustin, Germany.

Results of this open-label study, called CANAKINUMAB FIRST, were presented as late-breaking findings at the European Alliance of Associations for Rheumatology (EULAR) 2024 Annual Meeting.

“Steroid-free, first-line treatment with canakinumab led to sustained responses in most patients, with a considerable number achieving remission,” said Dr. Horneff, adding that the observation in this group is ongoing.
 

Building on Earlier Data

The efficacy of canakinumab was previously reported in anecdotal experiences and one small patient series published 10 years ago. Dr. Horneff noted that he has offered this drug off label to patients with challenging cases.

The objective was to evaluate canakinumab as a first-line monotherapy administered in the absence of glucocorticoids. The study was open to children aged 2-18 years with active sJIA/juvenile Still disease confirmed with published criteria. All were naive to biologic or nonbiologic disease-modifying antirheumatic drugs as well as steroids.

The median age of the children was 8.4 years. A total of 60% were men. The median disease duration at the time of entry was 1.2 months. Most had fever (95%) and rash (80%) with high levels of inflammatory markers at baseline. The mean number of painful joints was 3.1, and the mean number of systemic manifestations was 2.8. No patient was without any systemic involvement, but four of the patients did not have any painful joints.

At enrollment, patients were scheduled to receive three injections of canakinumab at monthly intervals during an active treatment phase, after which they entered an observation phase lasting 40 weeks. In the event of nonresponse or flares in either phase, they were transitioned to usual care.
 

Symptoms Resolve After Single Injection

After the first injection, active joint disease and all systemic manifestations resolved in 16 (80%) of the 20 patients. Joint activity and systemic manifestations also remained controlled after the second and third injections in 16 of the 20 patients.

One patient in this series achieved inactive disease after a single injection but developed what appeared to be a treatment-related allergic reaction. He received no further treatment and was excluded from the study, although he is being followed separately.

“According to sJADAS [systemic JIA Disease Activity Score] criteria at month 3, 14 had inactive disease, three had minimal disease activity, and one patient had moderate disease activity,” Dr. Horneff said.

At week 24, or 3 months after the last injection, there was still no joint activity in 16 patients. Systemic manifestations remained controlled in 13 patients, but 1 patient by this point had a flare. Another flare occurred after this point, and other patients have not yet completed the 52-week observation period.

“Of the 10 patients who remained in the study and have completed the 52-week observation period, eight have had a drug-free remission,” Dr. Horneff said.
 

MAS Event Observed in One Patient

In addition to the allergic skin reaction, which was considered probably related to the study drug, there were three flares, one of which was a macrophage activation syndrome (MAS) event. The MAS occurred 8 weeks after the last injection, but it was managed successfully.

Of 30 infections that developed during the observation period, 18 involved the upper airway. All were treated successfully. There were also two injection-site reactions and one case of cytopenia.

Among the studies planned for follow-up, investigators will examine genomic and gene activation in relation to disease activity and the effect of canakinumab.

Comoderator of the abstract session and chair of the EULAR 2024 Abstract Selection Committee, Christian Dejaco, MD, PhD, a consultant rheumatologist and associate professor at the Medical University of Graz in Graz, Austria, suggested that these are highly encouraging data for a disease that does not currently have any approved therapies. Clearly, larger studies with a longer follow-up period are needed, but he pointed out that phase 3 trials in a rare disease like sJIA are challenging.

Because of the limited number of cases, “it will be difficult to conduct a placebo-controlled trial,” he pointed out. However, he hopes this study will provide the basis for larger studies and sufficient data to lead to an indication for this therapy.

In the meantime, he also believes that these data are likely to support empirical use in a difficult disease, even in advance of formal regulatory approval.

“We heard that canakinumab is already being used off label in JIA, and these data might encourage more of that,” he said.

Dr. Horneff reported financial relationships with AbbVie, Boehringer Ingelheim, Celgene, Chugai, GlaxoSmithKline, Janssen, Merck Sharpe & Dohme, Novartis, Pfizer, Roche, Sanofi, and Sobe. Dr. Dejaco reported no potential conflicts of interest.

Because of the limited number of cases, “it will be difficult to conduct a placebo-controlled trial,” he pointed out. However, he hopes this study will provide the basis for larger studies and sufficient data to lead to an indication for this therapy.

In the meantime, he also believes that these data are likely to support empirical use in a difficult disease, even in advance of formal regulatory approval.

“We heard that canakinumab is already being used off label in JIA, and these data might encourage more of that,” he said.

Dr. Horneff reported financial relationships with AbbVie, Boehringer Ingelheim, Celgene, Chugai, GlaxoSmithKline, Janssen, Merck Sharpe & Dohme, Novartis, Pfizer, Roche, Sanofi, and Sobe. Dr. Dejaco reported no potential conflicts of interest.

VIENNA — The interleukin-1 receptor antagonist (IL-1RA) canakinumab provided control of systemic juvenile idiopathic arthritis (sJIA) without the use of glucocorticoids for up to a year in most study participants after three monthly injections.

In this study of 20 patients with newly diagnosed sJIA treated off glucocorticoids, fever was controlled after a single injection in all patients, and 16 patients reached the primary outcome of remission after three injections, said Gerd Horneff, MD, PhD, Asklepios Children’s Hospital, Sankt Augustin, Germany.

Results of this open-label study, called CANAKINUMAB FIRST, were presented as late-breaking findings at the European Alliance of Associations for Rheumatology (EULAR) 2024 Annual Meeting.

“Steroid-free, first-line treatment with canakinumab led to sustained responses in most patients, with a considerable number achieving remission,” said Dr. Horneff, adding that the observation in this group is ongoing.
 

Building on Earlier Data

The efficacy of canakinumab was previously reported in anecdotal experiences and one small patient series published 10 years ago. Dr. Horneff noted that he has offered this drug off label to patients with challenging cases.

The objective was to evaluate canakinumab as a first-line monotherapy administered in the absence of glucocorticoids. The study was open to children aged 2-18 years with active sJIA/juvenile Still disease confirmed with published criteria. All were naive to biologic or nonbiologic disease-modifying antirheumatic drugs as well as steroids.

The median age of the children was 8.4 years. A total of 60% were men. The median disease duration at the time of entry was 1.2 months. Most had fever (95%) and rash (80%) with high levels of inflammatory markers at baseline. The mean number of painful joints was 3.1, and the mean number of systemic manifestations was 2.8. No patient was without any systemic involvement, but four of the patients did not have any painful joints.

At enrollment, patients were scheduled to receive three injections of canakinumab at monthly intervals during an active treatment phase, after which they entered an observation phase lasting 40 weeks. In the event of nonresponse or flares in either phase, they were transitioned to usual care.
 

Symptoms Resolve After Single Injection

After the first injection, active joint disease and all systemic manifestations resolved in 16 (80%) of the 20 patients. Joint activity and systemic manifestations also remained controlled after the second and third injections in 16 of the 20 patients.

One patient in this series achieved inactive disease after a single injection but developed what appeared to be a treatment-related allergic reaction. He received no further treatment and was excluded from the study, although he is being followed separately.

“According to sJADAS [systemic JIA Disease Activity Score] criteria at month 3, 14 had inactive disease, three had minimal disease activity, and one patient had moderate disease activity,” Dr. Horneff said.

At week 24, or 3 months after the last injection, there was still no joint activity in 16 patients. Systemic manifestations remained controlled in 13 patients, but 1 patient by this point had a flare. Another flare occurred after this point, and other patients have not yet completed the 52-week observation period.

“Of the 10 patients who remained in the study and have completed the 52-week observation period, eight have had a drug-free remission,” Dr. Horneff said.
 

MAS Event Observed in One Patient

In addition to the allergic skin reaction, which was considered probably related to the study drug, there were three flares, one of which was a macrophage activation syndrome (MAS) event. The MAS occurred 8 weeks after the last injection, but it was managed successfully.

Of 30 infections that developed during the observation period, 18 involved the upper airway. All were treated successfully. There were also two injection-site reactions and one case of cytopenia.

Among the studies planned for follow-up, investigators will examine genomic and gene activation in relation to disease activity and the effect of canakinumab.

CHICAGO — Adding carboplatin to standard anthracycline/taxane treatment for early-stage triple-negative breast cancer (TNBC) improves event-free and overall survival in the neoadjuvant and adjuvant setting, according to a phase 3 trial presented at the annual meeting of the American Society of Clinical Oncology (ASCO).

The outcomes of the South Korean study, dubbed PEARLY, provide strong evidence for incorporating carboplatin into both the neoadjuvant and adjuvant settings in patients with early-stage TNBC, said lead investigator and presenter Joohyuk Sohn, MD, PhD, a medical oncologist at Yonsei University, Seoul, South Korea.

In early-stage TNBC, carboplatin is already being incorporated into the neoadjuvant setting on the basis of trial results from KEYNOTE-522 that demonstrated improved pathologic complete response rates and event-free survival with the platinum alongside pembrolizumab.

However, the overall survival benefit of carboplatin in this setting remains unclear, as does the benefit of platinum add-on in the adjuvant setting, Dr. Sohn explained.

Dr. Sohn and colleagues randomized 868 patients evenly to either standard treatment — doxorubicin, anthracycline, and cyclophosphamide followed by a taxane — or an experimental arm that added carboplatin to the taxane phase of treatment.

About 30% of women were treated in the adjuvant setting, the rest in the neoadjuvant setting. The two arms of the study were generally well balanced — about 80% of patients had stage II disease, half were node negative, and 11% had deleterious germline mutations.

The primary endpoint, event-free survival, was broadly defined. Events included disease progression, local or distant recurrence, occurrence of a second primary cancer, inoperable status after neoadjuvant therapy, or death from any cause.

Adding carboplatin increased 5-year event-free survival rates from 75.1% to 82.3% (hazard ratio [HR], 0.67; P = .012) with the benefit holding across various subgroup analyses and particularly strong for adjuvant carboplatin (HR, 0.26).

Five-year overall survival was also better in the carboplatin arm — 90.7% vs 87% in the control arm (HR, 0.65; 95% CI, 0.42-1.02) — but that benefit did not reach statistical significance (P = .057)

Invasive disease-free survival (HR, 0.73) and distant recurrence-free survival (HR, 0.77) favored carboplatin, but the results also weren’t statistically significant.

Overall, 46% of patients had a pathologic complete response with carboplatin vs nearly 40% in the control arm. The pathologic complete response benefit from carboplatin add-on was consistent with past reports.

As expected, adding carboplatin to treatment increased hematologic toxicity and other adverse events, with three-quarters of patients experiencing grade 3 or worse adverse events vs 56.7% of control participants. There was one death in the carboplatin arm from pneumonia and two in the control arm — one from septic shock and the other from suicide.

Dr. Sohn and colleagues, however, did not observe a quality of life difference between the two groups.

“The PEARLY trial provides compelling evidence for including carboplatin in the treatment of early-stage TNBC,” Dr. Sohn concluded, adding that the results underscore the benefit in the neoadjuvant setting and suggest “potential applicability in the adjuvant setting post surgery.”

Study discussant Javier Cortes, MD, PhD, believes that the PEARLY provides a strong signal for adding carboplatin in the adjuvant setting.

“That’s something I would do in my clinical practice,” said Dr. Cortes, head of the International Breast Cancer Center in Barcelona, Spain. “After ASCO this year, I would offer taxanes plus carboplatin following anthracyclines.”

An audience member, William Sikov, MD, a breast cancer specialist at Brown University in Providence, Rhode Island, said he hopes “we’ve reached the end of a road that started many years ago in terms of incorporating carboplatin as part of neoadjuvant and adjuvant therapy for triple-negative breast cancer, where we finally [reach] consensus that this is necessary in our triple-negative patients.”

The work was funded by the government of South Korea and others. Dr. Sohn reported stock in Daiichi Sankyo and research funding from Daiichi and other companies. Dr. Cortes disclosed numerous industry ties, including honoraria, research funding, and/or travel expenses from AstraZeneca, Daiichi, and others.

At the recent American Diabetes Association (ADA) Scientific Sessions, researchers unveiled promising data on a novel antimicrobial peptide PL-5 spray. This innovative treatment shows significant promise for managing mild to moderate infected diabetic foot ulcers. 

Of the 1.6 million people with diabetes in the United States and the tens of millions of similar people worldwide, 50% will require antimicrobials at some time during their life cycle. Diabetic foot infections are difficult to treat because of their resistance to conventional therapies, often leading to severe complications, including amputations. 

To address this issue, the antimicrobial peptide PL-5 spray was developed with a novel mechanism of action to potentially improve treatment outcomes. The study aimed to assess the clinical efficacy and safety of the PL-5 spray combined with standard debridement procedures in treating mild to moderate diabetic foot ulcers.

This multicenter, randomized, double-blind, placebo-controlled clinical trial was conducted in four hospitals across China. Participants with mild to moderate diabetic foot ulcers were randomly assigned in a 2:1 ratio to either the PL-5 group or the placebo group, both receiving standard debridement. The primary endpoint was clinical efficacy at day 1 after the end of treatment (EOT1). Secondary endpoints included clinical efficacy at day 7 (EOT7), microbiological efficacy, drug-resistant bacteria clearance rate, wound healing rate, and safety outcomes evaluated at both EOT1 and EOT7.

The study included 47 participants, with 32 in the PL-5 group and 15 in the placebo group. Both groups had statistically comparable demographic and clinical characteristics. The primary endpoint showed a higher clinical efficacy (cure/improvement ratio) in the PL-5 group, compared with the control group (1.33 vs 0.55; P =.0764), suggesting a positive trend but not reaching statistical significance in this population.

Among the secondary endpoints, clinical efficacy at EOT7 was significantly higher in the PL-5 group than in the control group (1.6 vs 0.86). Microbial eradication rates were notably better in the PL-5 group at both EOT1 (57.89% vs 33.33%) and EOT7 (64.71% vs 40.00%). The clearance rates of drug-resistant bacteria were also higher in the PL-5 group at EOT1 (71.43% vs 50%).

Of importance, safety parameters showed no significant differences between the two groups (24.24% vs 33.33%), highlighting the favorable safety profile of PL-5 spray.

The study presented at the ADA Scientific Sessions provides a glint of promising evidence supporting the potential efficacy and safety of PL-5 spray in treating mild to moderate diabetic foot infections. Despite the limited sample size, the results suggest that PL-5 spray may enhance the recovery speed of diabetic foot wounds, particularly in clearing drug-resistant bacterial infections. These findings justify further investigation with larger sample sizes to confirm or refute the efficacy and potentially establish PL-5 spray as a standard treatment option in diabetic foot care.

The novel antimicrobial peptide PL-5 spray shows potential in addressing the challenging issue of diabetic foot infections. This recent ADA presentation sparked significant interest and discussions about the future of diabetic foot ulcer treatments, emphasizing the importance of innovative approaches in managing complex diabetic complications.
