The Food and Drug Administration has approved the oral poly (ADP-ribose) polymerase inhibitor talazoparib (Talzenna, Pfizer) plus enzalutamide (Xtandi) to treat homologous recombination repair (HRR) gene–mutated metastatic castration-resistant prostate cancer.

Talazoparib is already approved for adults with deleterious or suspected deleterious germline BRCA-mutated HER2-negative locally advanced or metastatic breast cancer. The new approval, granted following priority review, is based on findings from the randomized, placebo-controlled, phase 3 TALAPRO-2 trial, published in The Lancet.

The 399 patients in the study were randomly assigned in a 1:1 ratio to receive either enzalutamide 160 mg daily plus either talazoparib 0.5 mg or placebo daily. Median radiographic progression-free survival (PFS) was not reached in the treatment group; it was 13.8 months in the placebo group (hazard ratio, 0.45). In an exploratory analysis by BRCA mutation status, patients with BRCA-mutated disease who received talazoparib exhibited an even stronger median radiographic PFS (HR, 0.20; not reached vs. 11 months) in comparison with those without BRCA-mutated disease (HR, 0.72; 24.7 vs. 16.7 months).

Serious adverse reactions occurred in 30% of patients who received talazoparib plus enzalutamide. The most common serious adverse reactions, reported in more than 2% of patients, included anemia (9%) and fracture (3%). Discontinuation of talazoparib occurred in 10% of patients, according to a Pfizer statement.

Pfizer also noted that a marketing authorization application for the drug combination has been accepted for review by the European Medicines Agency.

“Despite treatment advancement in metastatic castration-resistant prostate cancer, the disease can progress quickly, and many patients may only receive one line of therapy,” lead investigator Neeraj Agarwal, MD, of the Huntsman Cancer Institute, University of Utah, Salt Lake City, said in a statement. Patients with metastatic castration-resistant prostate cancer harboring HRR genetic alterations have even worse outcomes, and thus the FDA’s approval of the talazoparib and enzalutamide combination “represents a treatment option deserving of excitement and attention.”

Shortages of carboplatin and cisplatin have become widespread among major cancer centers, according to a survey released this week from the National Comprehensive Cancer Network.

The survey, which included responses from 27 NCCN member institutions, revealed that 93% are experiencing a shortage of carboplatin and that 70% have reported a shortage of cisplatin.

“This is an unacceptable situation,” Robert W. Carlson, MD, NCCN’s chief executive offer, said in the statement released by the network.

“We are hearing from oncologists and pharmacists across the country who have to scramble to find appropriate alternatives for treating their patients with cancer right now,” Dr. Carlson said. And while the survey results show patients are still able to get lifesaving care, “it comes at a burden to our overtaxed medical facilities.”

The NCCN called on the federal government, the pharmaceutical industry, providers, and payers to take steps to “help mitigate any impacts” from this cancer drug shortage.

“We need to work together to improve the current situation and prevent it from happening again in the future,” Dr. Carlson stressed.

Carboplatin and cisplatin, which are frequently used together for systemic treatment, are highly effective therapies prescribed to treat many cancer types, including lung, breast, and prostate cancers, as well as leukemias and lymphomas. An estimated 500,000 new patients with cancer receive these agents each year.

The current survey, conducted over the last week of May, found that 100% of responding centers are able to continue to treat patients who need cisplatin without delays.

The same cannot be said for carboplatin: only 64% of centers said they are still able to continue treating all current patients receiving the platinum-based therapy. Among 19 responding centers, 20% reported that they were continuing carboplatin regimens for some but not all patients. And 16% reported treatment delays from having to obtain prior authorization for modified treatment plans, though none reported denials.

“Carboplatin has been in short supply for months but in the last 4 weeks has reached a critical stage,” according to one survey comment. “Without additional inventory many of our sites will be out of drug by early next week.”

In response to the survey question, “Is your center experiencing a shortage of carboplatin,” others made similar comments:

• “Current shipments from established manufacturers have been paused.”
• “The supply of carboplatin available is not meeting our demands.”
• “Without additional supply in early June, we will have to implement several shortage mitigation strategies.”

Survey respondents also addressed whether manufacturers or suppliers have provided any indication of when these drugs will become readily available again. For both drugs, about 60% of respondents said no. And for those who do receive updates, many noted that the “information is tentative and variable.”

Respondents indicated that other cancer agents, including methotrexate (67%) and 5FU (26%), are also in short supply at their centers.

The shortage and the uncertainty as to when it will end are forcing some centers to develop conservation and mitigation strategies.

The NCCN has broadly outlined how the federal government, the pharmaceutical industry, providers, and payers can help with prevention and mitigation. The NCCN has called on the federal government and the pharmaceutical industry to work to secure a steady supply of core anticancer drugs and has asked payers to “put patients first and provide flexible and efficient systems of providing coverage for alternative therapies replacing anti-cancer drugs that are unavailable or in shortage.”

Overall, the survey results “demonstrate the widespread impact of the chemotherapy shortage,” said Alyssa Schatz, MSW, senior director of policy and advocacy for NCCN. “We hope that by sharing this survey and calling for united action across the oncology community, we can come together to prevent future drug shortages and ensure quality, effective, equitable, and accessible cancer care for all.”

The U.S. Food and Drug Administration has approved avapritinib (AYVAKIT, Blueprint Medicines) for the treatment of adults with indolent systemic mastocytosis. The new approval, which expands use of the drug to patients with indolent systemic mastocytosis, represents the “first and only approved medicine” to treat this disease, according to the company press statement.

Avapritinib, a selective KIT mutation-targeted tyrosine kinase inhibitor, was approved in 2021 to treat advanced systemic mastocytosis, a rare and potentially fatal hematologic disorder. Nonadvanced forms include indolent or smoldering disease; advanced disease can progress to leukemia. The expanded approval now covers patients with indolent disease, which represents the majority of patients with systemic mastocytosis.

The drug is also approved for adults with unresectable or metastatic GIST that harbors a platelet-derived growth factor receptor alpha exon 18 mutation.

The approval is based on data from the phase 2 PIONEER trial. In the trial, 222 patients with moderate to severe indolent, systemic mastocytosis* were randomly assigned in a 2:1 ratio to receive either avapritinib 25 mg once daily plus best supportive care or placebo plus best supportive care.

The findings, published in February, revealed that patients who received avapritinib experienced significantly greater improvements in total symptom scores at 24 weeks (–15.6 vs. –9.2 for control patients). Significantly more patients in the avapritinib arm achieved greater than or equal to 50% reductions in serum tryptase (54% vs. 0%), bone marrow mast cell aggregates (53% vs. 23%), and KIT D816V variant allele fraction (68% vs. 6%).

Most adverse reactions were mild to moderate in severity and included eye edema, dizziness, peripheral edema, and flushing. Fewer than 1% of patients discontinued treatment because of serious adverse reactions.

“People with indolent systemic mastocytosis are significantly impacted by their disease symptoms, and many individuals self-isolate at home to protect against unpredictable external triggers,” Judith Kain Emmel, board chair of the Mast Cell Disease Society, said in the company press release. “Today’s approval is a historic moment for the [systemic mastocytosis] community and offers new hope for patients and their families.

Thrombophilia testing should be limited to specific circumstances, including when venous thromboembolism (VTE) is provoked by nonsurgical risk factors such as pregnancy or oral contraception use, according to new clinical practice guidelines released by the American Society of Hematology. Individuals with a family history of VTE and high-risk thrombophilia, and those with VTE at unusual body sites should also be tested, the guidelines panel agreed.

“These guidelines will potentially change practice – we know that providers and patients will make a shared treatment decision and we wanted to outline specific scenarios to guide that decision,” panel cochair and first author Saskia Middeldorp, MD, PhD, explained in a press release announcing the publication of the guidelines in Blood Advances.

Dr. Middeldorp is a professor of medicine and head of the department of internal medicine at Radboud University Medical Center, Nijmegen, the Netherlands.

The guidelines are the latest in an ASH series of VTE-related guidelines. ASH convened a multidisciplinary panel with clinical and methodological expertise to develop the guidelines, which were subject to public comment, and they “provide recommendations informed by case-based approaches and modeling to ensure the medical community can better diagnose and treat thrombophilia and people with the condition can make the best decisions for their care,” the press release explains.

Thrombophilia affects an estimated 10% of the population. Testing for the clotting disorder can be costly, and the use of testing to help guide treatment decisions is controversial.

“For decades there has been dispute about thrombophilia testing,” Dr. Middeldorp said. “We created a model about whether and when it would be useful to test for thrombophilia, and based on the model, we suggest it can be appropriate in [the specified] situations.

The panel agreed on 23 recommendations regarding thrombophilia testing and management. Most are based on “very low certainty” in the evidence because of modeling assumptions.

However, the panel agreed on a strong recommendation against testing the general population before starting combined oral contraceptives (COC), and a conditional recommendation for thrombophilia testing in:

• Patients with VTE associated with nonsurgical major transient or hormonal risk factors
• Patients with cerebral or splanchnic venous thrombosis in settings where anticoagulation would otherwise be discontinued
• Individuals with a family history of antithrombin, protein C, or protein S deficiency when considering thromboprophylaxis for minor provoking risk factors and for guidance related to the use of COC or hormone therapy
• Pregnant women with a family history of high-risk thrombophilia types
• Patients with cancer at low or intermediate risk of thrombosis and with a family history of VTE

“In all other instances, we suggest not testing for thrombophilia,” said Dr. Middeldorp.

The ASH guidelines largely mirror those of existing guidelines from a number of other organizations, but the recommendation in favor of testing for thrombophilia in patients with VTE provoked by a nonsurgical major transient risk factor or associated with COCs, hormone therapy, pregnancy or postpartum is new and “may cause considerable discussion, as many currently view these VTE episodes as provoked and are generally inclined to use short-term anticoagulation for such patients,” the guideline authors wrote.

“It is important to note, however, that most guidelines or guidance statements on thrombophilia testing did not distinguish between major and minor provoking risk factors, which current science suggests is appropriate,” they added.

Another novel recommendation is the suggestion to test for hereditary thrombophilia to guide the use of thromboprophylaxis during systemic treatment in ambulatory patients with cancer who are at low or intermediate risk for VTE and who have a family history of VTE.

“This new recommendation should be seen as a new application of an established risk stratification approach,” they said.

Additional research is urgently needed, particularly “large implementation studies comparing the impact, in terms of outcomes rates, among management strategies involving or not involving thrombophilia testing,” they noted.

The guideline was wholly funded by ASH. Dr. Middeldorp reported having no conflicts of interest.

• Patients with VTE associated with nonsurgical major transient or hormonal risk factors
• Patients with cerebral or splanchnic venous thrombosis in settings where anticoagulation would otherwise be discontinued
• Individuals with a family history of antithrombin, protein C, or protein S deficiency when considering thromboprophylaxis for minor provoking risk factors and for guidance related to the use of COC or hormone therapy
• Pregnant women with a family history of high-risk thrombophilia types
• Patients with cancer at low or intermediate risk of thrombosis and with a family history of VTE

“In all other instances, we suggest not testing for thrombophilia,” said Dr. Middeldorp.

The ASH guidelines largely mirror those of existing guidelines from a number of other organizations, but the recommendation in favor of testing for thrombophilia in patients with VTE provoked by a nonsurgical major transient risk factor or associated with COCs, hormone therapy, pregnancy or postpartum is new and “may cause considerable discussion, as many currently view these VTE episodes as provoked and are generally inclined to use short-term anticoagulation for such patients,” the guideline authors wrote.

“It is important to note, however, that most guidelines or guidance statements on thrombophilia testing did not distinguish between major and minor provoking risk factors, which current science suggests is appropriate,” they added.

Another novel recommendation is the suggestion to test for hereditary thrombophilia to guide the use of thromboprophylaxis during systemic treatment in ambulatory patients with cancer who are at low or intermediate risk for VTE and who have a family history of VTE.

“This new recommendation should be seen as a new application of an established risk stratification approach,” they said.

Additional research is urgently needed, particularly “large implementation studies comparing the impact, in terms of outcomes rates, among management strategies involving or not involving thrombophilia testing,” they noted.

The guideline was wholly funded by ASH. Dr. Middeldorp reported having no conflicts of interest.

The Food and Drug Administration has acknowledged reports of squamous cell carcinoma (SCC) of the breast as well as lymphomas associated with postmastectomy breast implants.

Findings from a large cohort study suggest the incidence of SCC is negligible. The analysis found one case of SCC among nearly 57,000 women who had undergone breast implant reconstruction over 421,227 person-years of follow-up.

The authors also confirmed the known risk of breast implant–associated anaplastic large-cell lymphoma (ALCL), identifying five cases in the population, which was considered a “significantly elevated” risk.

Although patients with breast cancer who are eligible for mastectomy should be counseled on the risks for cancer after implant reconstruction, patients “should not be dissuaded from pursuing implant-based reconstruction because of the risk of SCC,” lead author Connor J. Kinslow, MD, of Columbia University, New York, and colleagues concluded.

SCC cases associated with breast implants are distinct from breast implant–associated ALCL, the authors noted, explaining that this lymphoma “is the subject of a boxed warning on all saline- and silicone gel–filled breast implants since 2020.” 

The results were published in a research letter in JAMA Surgery.

Last September, a safety communication from the FDA highlighted reports of SCC and other lymphomas associated with breast implants. The FDA said it was aware of fewer than 20 cases of SCC.

Following the safety communication, Dr. Kinslow and colleagues assessed SCC risk among 56,785 women who underwent cancer-directed mastectomy with implant reconstruction for breast tumors.

Women in the cohort were diagnosed between 2000 and 2018 and included in the Surveillance, Epidemiology, and End Results (SEER) 17 database. Patients had a median age of 51 years; most (84%) where White, 8.1% were Black, 7.4% were Asian or Pacific Islander, 0.4% were American Indian/Alaska Native, and race was unknown in 0.4%.

Across 421,227 person-years of follow-up, the team identified one case of SCC, corresponding to an incidence rate of 2.37 per million person-years vs. an expected incidence of 1.02 per million person-years in the general population. Although the 2.33 standardized incidence ratio (SIR) “appeared elevated vs. the general population,” it was “not significant given the low incidence” (95% confidence interval, 0.06-13.0).

The team also identified five cases of breast implant–associated ALCL. That corresponded to an incidence rate of 11.9 per million person-years compared with an expected incidence of 0.29 per million person-years – for a significantly elevated SIR of 40.9. The authors also noted more than 1,000 reported cases of breast implant–associated ALCL previous as well as a robust association with implants.

Regarding SCC, “whether the observed elevated risk is associated with the implants is difficult to interpret because it is based on only one case and wide [confidence intervals],” the authors said. But, overall, “we found that the incidence rate of SCC was extraordinarily low and of minimal public health concern.”

The effects of maribavir (Levtencity) for the treatment of resistant or refractory post-transplant cytomegalovirus (CMV) infection persisted at 52-week follow-up in hematopoietic stem cell and solid organ transplant patients from the pivotal phase 3 SOLSTICE trial.

Overall mortality in the 109 patients from these subcohorts from SOLSTICE was lower, compared with mortality reported for similar populations treated with conventional therapies used to treat relapsed or refractory (R/R) CMV, according to findings presented in April at the annual meeting of the European Society for Bone and Marrow Transplantation.

“These results, in addition to the superior efficacy in CMV clearance observed for maribavir in SOLSTICE provide supportive evidence of the potential for the long-term benefit of maribavir treatment for post-transplant CMV infection,” Ishan Hirji, of Takeda Development Center Americas, and colleagues reported during a poster session at the meeting.

A retrospective chart review of the 41 hematopoietic stem cell transplant (HSCT) patients and 68 solid organ transplant (SOT) patients randomized to receive maribavir showed an overall mortality rate of 15.6% at 52 weeks after initiation of treatment with the antiviral agent. Among the HSCT patients, 14 deaths occurred (34.1%), with 8 occurring during the study periods and 6 occurring during follow-up. Among the SOT patients, three deaths occurred (4.4%), all during follow-up chart review.

Causes of death included underlying disease relapse in four patients, infection other than CMV in six patients, and one case each of CMV-related factors, transplant-related factors, acute lymphoblastic leukemia, and septic shock. Causes of death in the SOT patients included one case each of CMV-related factors, anemia, and renal failure.

“No patients had new graft loss or retransplantation during the chart review period,” the investigators noted.

The findings are notable as CMV infection occurs in 30%-70% of HSCT recipients and 16%-56% of SOT recipients and can lead to complications, including transplant failure and death. Reported 1-year mortality rates following standard therapies for CMV range from 31% to 50%, they explained.

Patients in the SOLSTICE trial received 8 weeks of treatment and were followed for 12 additional weeks. CMV clearance at the end of treatment was 55.7% in the maribavir treatment arm versus 23.9% in a control group of patients treated with investigator choice of therapy. As reported by this news organization, the findings formed the basis for U.S. Food and Drug Administration approval of maribavir in November 2021.

The current analysis included a chart review period that started 1 day after the SOLSTICE trial period and continued for 32 additional weeks.

These long-term follow-up data confirm the benefits of maribavir for the treatment of post-transplant CMV, according to the investigators, and findings from a separate study reported at the ESBMT meeting underscore the importance of the durable benefits observed with maribavir treatment.

For that retrospective study, Maria Laura Fox, of Vall d’Hebron Institute of Oncology, Barcelona, and colleagues pooled de-identified data from 250 adult HSCT recipients with R/R CMV who were treated with agents other than maribavir at transplant centers in the United States or Europe. They aimed to “generate real-world evidence on the burden of CMV infection/disease in HSCT recipients who had refractory/resistant CMV or were intolerant to current treatments.”

Nearly 92% of patients received two or more therapies to treat CMV, and 92.2% discontinued treatment or had one or more therapy dose changes or discontinuation, and 42 patients failed to achieve clearance of the CMV index episode.

CMV recurred in 35.2% of patients, and graft failure occurred in 4% of patients, the investigators reported.

All-cause mortality was 56.0%, and mortality at 1 year after identification of R/R disease or treatment intolerance was 45.2%, they noted, adding that the study results “highlight the real-world complexities and high burden of CMV infection for HSCT recipients.”

“With available anti-CMV agents [excluding maribavir], a notable proportion of patients failed to achieve viremia clearance once developing RRI [resistant, refractory, or intolerant] CMV and/or experienced recurrence, and were at risk of adverse outcomes, including myelosuppression and mortality. There is a need for therapies that achieve and maintain CMV clearance with improved safety profiles,” they concluded.

Both studies were funded by Takeda Development Center Americas, the maker of Levtencity. Ms. Hirji is an employee of Takeda and reported stock ownership. Ms. Fox reported relationships with Sierra Oncology, GlaxoSmithKline, Bristol Myers Squibb, Novartis, and AbbVie.

As many as 40% of lumpectomies leave positive margins that necessitate a second surgery, but a novel fluorescent imaging agent used along with a direct visualization system may improve complete resection rates, new phase 3 findings show.

Pegulicianine (Lumisight), an investigational and activatable fluorescent imaging agent used with a novel direct visualization system, helped identify residual tumor or circumvent second surgeries in about 10% of patients in the trial.

Use of the agent and direct visualization system – both from Lumicell and currently under review by the Food and Drug Administration – could provide more complete resection for patients with early breast cancer and avert the need for reexcisions, the investigators write.

The findings were published online in NEJM Evidence and were subsequently presented at the annual meeting of the American Society of Breast Surgeons.

Local recurrence following lumpectomy increases the risk of dying from breast cancer, and the risk of local recurrence is directly linked to inadequate tumor removal during lumpectomy. In about 20%-40% of lumpectomies, positive margins are identified after surgery.

To improve patient outcomes, investigators assessed whether a novel fluorescence-guided surgery system helped surgeons perform more complete resections during lumpectomy.

In the Novel Surgical Imaging for Tumor Excision (INSITE) trial, 392 patients were randomly assigned to undergo pegulicianine fluorescence-guided surgery (n = 357) or standard lumpectomy (n = 35).

To prevent surgeons from performing a smaller than standard lumpectomy in anticipation of using the pegulicianine fluorescence-guided system, patients were randomly assigned to the pegulicianine fluorescence-guided surgery group or the control group. The groups were revealed only after the surgeon completed the standard lumpectomy.

“Randomization was not designed to provide a control group for analysis of device performance,” The authors explain. “In this study design, each patient undergoing pegulicianine fluorescence-guided surgery served as her own control,” they write. The investigators compared final margin pathology after standard lumpectomy and after guided surgery. Those in the control group were included in the safety analysis.

Study participants were women aged 18 years or older who were undergoing lumpectomy for stage I–III breast cancer and/or ductal carcinoma in situ. All patients received pegulicianine 1.0 mg/kg via a 3-minute intravenous infusion 2-6 hours before surgery.

The agent produces a signal at sites of residual tumor, and a handheld probe illuminates the cavity during surgery. A tumor detection algorithm then analyzes and displays the images to the surgeon in real time – an overall process that adds about 7 minutes to the operative procedure, the authors say.

Investigators identified invasive cancers in 316 patients and in situ cancers in 76 patients. Among the 357 patients in the treatment group, 27 (7.6%) were found to have residual tumor after standard lumpectomy. For 22 patients, cavity orientations were deemed negative on standard margin evaluations, the authors report.

With use of pegulicianine fluorescence-guided surgery, positive margins were converted to negative margins for 9 of 62 patients (14.5%), potentially averting a second surgery in those patients.

Overall, the authors say that pegulicianine fluorescence-guided surgery removed residual tumor (27 of 357) or avoided second surgeries (9 of 357) in 10% of patients in the trial.

The current trial findings confirm results regarding the safety and efficacy of pegulicianine fluorescence-guided surgery and the direct visualization system that were reported in a prior multicenter feasibility study, the authors say.

Pegulicianine fluorescence-guided surgery met prespecified thresholds for removal of residual tumor and specificity, at 85.2%, but did not meet the prespecified threshold for sensitivity, which was only 49.3%.

The rate of serious adverse events with pegulicianine was 0.5% (two patients), similar to that of other contrast agents. Administration of the agent was stopped because of adverse events for six patients, the investigators write.

Serious adverse events included grade 3 hypersensitivity in one patient and an anaphylactic reaction in another. The other four adverse events included an allergic reaction, milder hypersensitivity, nausea, and pegulicianine extravasation. All adverse events resolved, and patients proceeded to standard lumpectomy.

Overall, the trial findings “suggest that a more complete breast cancer resection may be achieved” with pegulicianine fluorescence-guided surgery and the direct visualization system, lead investigator Barbara Smith, MD, PhD, director of the breast program at Massachusetts General Hospital and professor of surgery at Harvard Medical School, both in Boston, said in a press release. “Given the low complication rate, minimal added operative time and, most importantly, the discovery of additional cancer left behind after a lumpectomy, the Lumicell [system] has the potential to be a critical adjunct to enhance standard practice for breast cancer patients.”

The system also has the potential to reduce “the patient burden of additional surgery” and decrease “costs associated with a return to the operating room,” the authors conclude.

The INSITE trial was funded by Lumicell and the National Institutes of Health. Dr. Smith reported unpaid research collaboration with Lumicell.

Overall, the trial findings “suggest that a more complete breast cancer resection may be achieved” with pegulicianine fluorescence-guided surgery and the direct visualization system, lead investigator Barbara Smith, MD, PhD, director of the breast program at Massachusetts General Hospital and professor of surgery at Harvard Medical School, both in Boston, said in a press release. “Given the low complication rate, minimal added operative time and, most importantly, the discovery of additional cancer left behind after a lumpectomy, the Lumicell [system] has the potential to be a critical adjunct to enhance standard practice for breast cancer patients.”

The system also has the potential to reduce “the patient burden of additional surgery” and decrease “costs associated with a return to the operating room,” the authors conclude.

The INSITE trial was funded by Lumicell and the National Institutes of Health. Dr. Smith reported unpaid research collaboration with Lumicell.

As many as 40% of lumpectomies leave positive margins that necessitate a second surgery, but a novel fluorescent imaging agent used along with a direct visualization system may improve complete resection rates, new phase 3 findings show.

Pegulicianine (Lumisight), an investigational and activatable fluorescent imaging agent used with a novel direct visualization system, helped identify residual tumor or circumvent second surgeries in about 10% of patients in the trial.

Use of the agent and direct visualization system – both from Lumicell and currently under review by the Food and Drug Administration – could provide more complete resection for patients with early breast cancer and avert the need for reexcisions, the investigators write.

The findings were published online in NEJM Evidence and were subsequently presented at the annual meeting of the American Society of Breast Surgeons.

Local recurrence following lumpectomy increases the risk of dying from breast cancer, and the risk of local recurrence is directly linked to inadequate tumor removal during lumpectomy. In about 20%-40% of lumpectomies, positive margins are identified after surgery.

To improve patient outcomes, investigators assessed whether a novel fluorescence-guided surgery system helped surgeons perform more complete resections during lumpectomy.

In the Novel Surgical Imaging for Tumor Excision (INSITE) trial, 392 patients were randomly assigned to undergo pegulicianine fluorescence-guided surgery (n = 357) or standard lumpectomy (n = 35).

To prevent surgeons from performing a smaller than standard lumpectomy in anticipation of using the pegulicianine fluorescence-guided system, patients were randomly assigned to the pegulicianine fluorescence-guided surgery group or the control group. The groups were revealed only after the surgeon completed the standard lumpectomy.

“Randomization was not designed to provide a control group for analysis of device performance,” The authors explain. “In this study design, each patient undergoing pegulicianine fluorescence-guided surgery served as her own control,” they write. The investigators compared final margin pathology after standard lumpectomy and after guided surgery. Those in the control group were included in the safety analysis.

Study participants were women aged 18 years or older who were undergoing lumpectomy for stage I–III breast cancer and/or ductal carcinoma in situ. All patients received pegulicianine 1.0 mg/kg via a 3-minute intravenous infusion 2-6 hours before surgery.

The agent produces a signal at sites of residual tumor, and a handheld probe illuminates the cavity during surgery. A tumor detection algorithm then analyzes and displays the images to the surgeon in real time – an overall process that adds about 7 minutes to the operative procedure, the authors say.

Investigators identified invasive cancers in 316 patients and in situ cancers in 76 patients. Among the 357 patients in the treatment group, 27 (7.6%) were found to have residual tumor after standard lumpectomy. For 22 patients, cavity orientations were deemed negative on standard margin evaluations, the authors report.

With use of pegulicianine fluorescence-guided surgery, positive margins were converted to negative margins for 9 of 62 patients (14.5%), potentially averting a second surgery in those patients.

Overall, the authors say that pegulicianine fluorescence-guided surgery removed residual tumor (27 of 357) or avoided second surgeries (9 of 357) in 10% of patients in the trial.

The current trial findings confirm results regarding the safety and efficacy of pegulicianine fluorescence-guided surgery and the direct visualization system that were reported in a prior multicenter feasibility study, the authors say.

Pegulicianine fluorescence-guided surgery met prespecified thresholds for removal of residual tumor and specificity, at 85.2%, but did not meet the prespecified threshold for sensitivity, which was only 49.3%.

The rate of serious adverse events with pegulicianine was 0.5% (two patients), similar to that of other contrast agents. Administration of the agent was stopped because of adverse events for six patients, the investigators write.

Serious adverse events included grade 3 hypersensitivity in one patient and an anaphylactic reaction in another. The other four adverse events included an allergic reaction, milder hypersensitivity, nausea, and pegulicianine extravasation. All adverse events resolved, and patients proceeded to standard lumpectomy.

Overall, the trial findings “suggest that a more complete breast cancer resection may be achieved” with pegulicianine fluorescence-guided surgery and the direct visualization system, lead investigator Barbara Smith, MD, PhD, director of the breast program at Massachusetts General Hospital and professor of surgery at Harvard Medical School, both in Boston, said in a press release. “Given the low complication rate, minimal added operative time and, most importantly, the discovery of additional cancer left behind after a lumpectomy, the Lumicell [system] has the potential to be a critical adjunct to enhance standard practice for breast cancer patients.”

The investigational drug motixafortide shows promise for improving the stem cell transplantation process in patients with multiple myeloma (MM), according to research led by investigators at Washington University in St. Louis.

Motixafortide, a   novel cyclic-peptide CXCR4 inhibitor with extended in vivo activity , appears to increase the number of stem cells that can be harvested from transplant candidates, thereby increasing the likelihood of successful transplant, the authors reported.

An application for a new drug approval is currently under review by the Food and Drug Administration.

In the prospective, international, phase 3 GENESIS clinical trial , motixafortide plus granulocyte colony-stimulating factor (G-CSF) – the standard therapy for mobilizing stem cells – significantly increased the number stem cells harvested, when compared with standard therapy plus placebo. After one collection procedure, the combination approach allowed for harvesting of an optimal number of cells in 88% versus 9% of patients who received G-CSF plus placebo. After two collections, optimal collection occurred in 92% versus 26% of patients in the groups, respectively, first author Zachary D. Crees, MD, and colleagues found.

Motixafortide plus G-CSF was also associated with a tenfold increase in the number of primitive stem cells that could be collected. These stem cells are particularly effective for reconstituting red blood cells, white blood cells, and platelets, which all are important for patients’ recovery, they noted.

Stem cells mobilized by motixafortide were also associated with increased expression of genes and genetic pathways involved in self-renewal and regeneration, which are also of benefit for increasing the effectiveness of stem cell transplantation.

The findings were published in Nature Medicine.

“Stem cell transplantation is central to the treatment of multiple myeloma, but some patients don’t see as much benefit because standard therapies can’t harvest enough stem cells for the transplant to be effective, senior author John F. DiPersio, MD, PhD, stated in a news release . “This study suggests motixafortide works extremely well in combination with [G-CSF] in mobilizing stem cells in patients with multiple myeloma.

“The study also found that the combination worked rapidly and was generally well tolerated by patients,” added Dr. DiPersio, the Virginia E. & Sam J. Goldman Professor of Medicine at Siteman Cancer Center at Barnes-Jewish Hospital and Washington University.

Dr. DiPersio is the lead author of another study investigating therapies beyond stem cell transplants. He and his colleagues recently reported the first comprehensive genomic and protein-based analysis of bone marrow samples from patients with multiple myeloma in an effort to identify targets for immunotherapies.

That study, published online in Cancer Research, identified 53 genes that could be targets, including 38 that are responsible for creating abnormal proteins on the surface of multiple myeloma cells; 11 of the 38 had not been previously identified as potential targets.

Dr. DiPersio and Dr. Crees, an assistant professor of medicine and the assistant clinical director of the Washington University Center for Gene and Cellular Immunotherapy, are also evaluating motixafortide’s potential for mobilizing stem cells to support “the genetic correction of the inherited disease sickle cell anemia.”

“This work is of particular importance because patients with sickle cell disease can’t be treated with G-CSF … due to dangerous side effects,” the news release stated. “The hope is that development of a novel, effective, and well-tolerated stem cell mobilizing regimen for a viral-based gene therapy approach using CRISPR-based gene editing will lead to improved outcomes for patients with sickle cell disease.”

The study published in Nature Medicine was supported by the National Institutes of Health and BioLineRx, which makes motixafortide. The study published in Cancer Research was supported by the Paula C. And Rodger O. Riney Blood Cancer Research Fund and the National Cancer Institute.

Dr. Crees reported research funding from BioLineRx. Dr. DiPersio reported relationships with Magenta Therapeutics, WUGEN, Incyte, RiverVest Venture Partners, Cellworks Group, Amphivena Therapeutics, NeoImmune Tech, Macrogenics, and BioLineRx.

The Food and Drug Administration has approved retifanlimab-dlwr (Zynyz), an intravenous programmed death–1 (PD-1) inhibitor, for the treatment of adults with metastatic or recurrent locally advanced Merkel cell carcinoma (MCC), the agency announced.

This marks the first regulatory approval for the PD-1 inhibitor. The FDA granted accelerated approval for the drug on the basis of tumor response rate and duration of response from the POD1UM-201 trial. Drugmaker Incyte said that “continued approval of Zynyz for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.”

MCC is a rare and aggressive skin cancer with a high rate of metastatic disease and an estimated 5-year overall survival of just 14% among those who present with metastatic disease. Incidence is rapidly increasing in the United States, particularly among adults older than 65 years, Incyte noted.

“More than a third of patients with MCC present with regional or distant metastases, which are associated with high rates of mortality,” principal author Shailender Bhatia, MD, of the University of Washington and Fred Hutchinson Cancer Center, both in Seattle, said in a news release. “The approval of Zynyz offers health care providers another first-line treatment option against MCC that can result in durable responses in patients with metastatic disease.”

POD1UM-201 was an open-label, single-arm, phase 2 study that evaluated the agent in 65 systemic treatment–naive adults with metastatic or recurrent locally advanced MCC.

Overall, 52% of patients had an objective response rate. A complete response was observed in 12 patients (18%), and a partial response was observed in 22 patients (34%).

Duration of response ranged from 1.1 to 24.9 months; 76% of responders experienced responses of 6 months or longer, and 62% experienced responses of 12 months or longer.

Study participants received a 500-mg dose of retifanlimab every 4 weeks for up to 24 weeks or until disease progression or unacceptable toxicity. Serious adverse events occurred in 22% of patients and most often included fatigue, arrhythmia, and pneumonitis; 11% of patients discontinued treatment because of serious adverse events.

Retifanlimab may cause a severe or life-threatening immune response during treatment or after discontinuation. Patients should be advised to immediately report any new or worsening signs or symptoms to their health care provider. Side effects can also be reported to the FDA.

Patients who are already depressed before they receive a lung cancer diagnosis are more likely to have a worse overall survival (OS), and the driver for this may be inflammation, suggests a new study.

The findings underscore the importance of assessing and treating depression in patients with cancer, particularly given the high rate of depression among those with lung cancer versus other types of cancer, the investigators said.

The study involved 186 patients with newly diagnosed stage IV non–small cell lung cancer (NSCLC), of whom 35% had self-reported moderate to severe depressive symptoms.

Depression was reliably associated with lung-relevant systemic inflammation responses (SIRs), which included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and Advanced Lung Cancer Inflammation Index (ALI) score.

These SIRs were prognostic for 2-year OS.

Overall mortality at 2 years was 61%. Higher NLRs and PLRs and lower ALI scores all predicted worse OS (hazard ratio, 1.91, 2.08, and 0.53, respectively).

The findings were published online in PLoS ONE (2023 Feb 24.

“These patients with high levels of depression are at much higher risk for poor outcomes,” but the key finding was that patients with the highest depression levels were driving the relationship, lead author Barbara Andersen, PhD, professor of psychology at Ohio State University, Columbus, stated in a press release.

“It was patients with high depression levels who had strikingly higher inflammation levels, and that is what really drove the correlation we saw,” she explained.

For example, 56% of patients with no depression symptoms or only mild depression symptoms had a PLR above the cutoff for dangerous levels of inflammation, compared with 42% whose PLR was below the cutoff. However, among those with high depression levels, 77% and 23% had a PLR above and below the cutoff, respectively.

“These highly depressed patients were 1.3-3 times more likely to have high inflammation levels, even after controlling for other factors related to inflammation biomarker levels, including demographics and smoking status,” Dr. Andersen noted.

“Depression levels may be as important or even more important than other factors that have been associated with how people fare with lung cancer,” she suggested.

In a previous study, the team controlled for baseline depression and found that “the trajectory of depression from diagnosis through 2 years (18 assessments) predicted NSCLC patients’ survival (HR, 1.09), above and beyond baseline depression, sociodemographics, smoking status, cell type, and receipt of targeted treatments and immunotherapies.”

“Taken together, data support psychological, behavioral, and biologic toxicities of depression capable of influencing treatment response and/or survival,” they wrote.

“The results may help explain why a substantial portion of lung cancer patients fail to respond to new immunotherapy and targeted treatments that have led to significantly longer survival for many people with the disease,” Dr. Andersen said.

The investigators concluded that “intensive study of depression among patients with NSCLC, combined with measures of cell biology, inflammation, and immunity, is needed to extend these findings and discover their mechanisms, with the long-term aim to improve patients’ quality of life, treatment responses, and longevity.”

This study was funded by the Ohio State University Comprehensive Cancer Center and Pelotonia through grants to individual authors. Dr. Andersen reported having no relevant disclosures.
