Aggressive Lymphomas

Syringe

Health Canada has approved a subcutaneous (SC) formulation of rituximab (Rituxan®) to treat patients with chronic lymphocytic leukemia (CLL).

The product is now approved for use in combination with fludarabine and cyclophosphamide to treat patients with previously treated or untreated CLL, Binet Stage B or C.

The SC formulation is intended to provide a more convenient delivery method than intravenous (IV) rituximab. The SC formulation enables administration of the drug in large volumes under the skin.

“The approval of Rituxan SC is exciting news and a meaningful advancement for those living with CLL, as intravenous treatments can take around 4 hours to receive, requiring patients to spend up to a half day sitting in the chemo suite,” said Robin Markowitz, chief executive officer of Lymphoma Canada.

“The administration of Rituxan SC only takes 7 minutes, giving patients valuable time back in their day.”

SAWYER study

Health Canada’s approval of SC rituximab is based on data from the phase 1b SAWYER study. This randomized study was conducted in patients with previously untreated CLL to investigate the pharmacokinetic profile, safety, and efficacy of SC rituximab in combination with chemotherapy.

Results from this study were published in The Lancet Haematology in March 2016.

The trial included 176 patients who were randomized to receive SC rituximab (1600 mg, n=88) or IV rituximab (500 mg/m², n=88) on day 1 from cycles 2 to 6. In cycle 1, both groups received IV rituximab (375 mg/m²) on day 0.

All patients also received fludarabine (IV 25 mg/m² on days 1-3 of all cycles or orally at either 25 mg/m² on days 1-5 of all cycles or 30-40 mg/m² on days 1-3 of all cycles) and cyclophosphamide (IV at 250 mg/m² on days 1-3 of all cycles or orally at either 150 mg/m² on days 1-5 of all cycles or 200-250 mg/m² on days 1-3 of all cycles) every 4 weeks for up to 6 cycles.

The primary endpoint was pharmacokinetic noninferiority of SC to IV rituximab assessed at cycle 5. At that time, the geometric mean trough serum concentration in the SC rituximab arm was noninferior to that in the IV arm—97.5 µg/mL and 61.5 µg/mL, respectively—with an adjusted geometric mean ratio of 1.53 (90% CI, 1.27 to 1.85).

Safety was a secondary endpoint, and efficacy was an exploratory endpoint.

The overall response rate was 85% in the SC arm and 81% in the IV arm. Complete response rates were 26% and 33%, respectively.

Rates of adverse events (AEs) were 96% in the SC arm and 91% in the IV arm. Rates of grade 3 or higher AEs were 69% and 71%, respectively, and rates of serious AEs were 29% and 33%, respectively.

The most common serious AE overall was febrile neutropenia, which occurred in 11% of patients in the SC arm and 4% in the IV arm.

The most common AEs of any grade (occurring in >20% of patients in either arm) were:

• Neutropenia—65% with SC and 58% with IV
• Thrombocytopenia—24% with SC and 26% with IV
• Anemia—13% with SC and 24% with IV
• Nausea—38% with SC and 35% with IV
• Vomiting—21% with SC and 22% with IV
• Pyrexia—32% with SC and 25% with IV
• Injection-site erythema—26% with SC and 0% with IV.

Local cutaneous reactions were reported in 42% of patients in the SC arm. The most common of these were injection-site erythema (26%) and injection-site pain (16%).

Voxtalisib, an investigational agent that targets both mTOR and multiple isoforms of PI3K, showed “promising” efficacy with acceptable safety in patients with relapsed or refractory follicular lymphoma (FL), results of a phase 2 trial indicate.

Among 46 patients with FL, the overall response rate was 41.3%, including five (10.9%) complete responses. The median progression-free survival in this group was 58 weeks, reported Jennifer R. Brown, MD, PhD, of the Dana-Farber Cancer Institute in Boston, and her colleagues.

“The observed activity of voxtalisib in relapsed or refractory follicular lymphoma, notable for inducing complete responses in 10.9% of patients, warrants further study,” the investigators wrote in a study published in the Lancet Haematology.

Efficacy of the drug was limited, however, against aggressive malignancies, including mantle cell lymphoma (MCL), diffuse large B-cell lymphoma (DLBCL), or chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL).

Voxtalisib (XL765) is a potent inhibitor of all four class I PI3Ks, as well as a less robust inhibitor of the mammalian target of rapamycin (mTOR). In contrast, idelalisib (Zydelig) – which is approved by the Food and Drug Administration for treatment of relapsed/refractory FL or for CLL, in combination with rituximab – inhibits only the delta isoform of PI3K, and does not have marked anti–mTOR properties.

The investigators conducted an open-label, nonrandomized trial of voxtalisib in 30 centers in the United States, Belgium, France, Germany, the Netherlands, and Australia.

Adults 18 years or older with relapsed or refractory MCL, FL, DLBCL or CLL/SLL with Eastern Cooperative Oncology Group performance status of 2 or less were enrolled. All patients received voxtalisib 50 mg orally twice daily in 28-day continuous dosing cycles until progression or unacceptable toxicity.

All patients who received more the 4 weeks of treatment and had both a baseline and one or more on-treatment tumor assessments were included in the efficacy analysis. Patients with lymphoma had received a median of three prior lines of therapy, and those with CLL had received a median of four prior lines.

The overall response rate in the entire study population was 18.3% (30 patients), including 22 partial and 8 complete responses. ORR rates were as follows:

• FL: 41.3% (19 of 46 patients).
• MCL: 11.9% (5 of 42 patients).
• DLBCL: 4.9% (2 of 41 patients).
• CLL/SLL: 11.4% (4 of 35 patients).

The safety analysis, which included all 167 patients enrolled, was consistent with that of previous studies of voxtalisib, the investigators said. The most frequently reported adverse events of any grade or type were diarrhea in 35% of patients, fatigue in 32%, nausea in 27%, pyrexia in 26%, cough 24%, and decreased appetite in 21%.

Grade 3 or greater adverse events include anemia in 12%, and pneumonia and thrombocytopenia in 8% each. Slightly more than half of all patients (58.1%) had a serious adverse event.

The investigators noted that voxtalisib’s short plasma half-life may explain the drug’s lack of efficacy against the aggressive lymphomas and CLL/SLL. Longer-acting formulations of the drug or more frequent dosing might address this problem, although the latter solution could be challenging for patients to follow, the investigators acknowledged.

In light of the results, no further studies of voxtalisib in CLL are planned, thought investigation of the drug alone or in combination with chemoimmunotherapy is warranted for patients with follicular lymphoma, the investigators wrote.

The study was funded by Sanofi. Dr. Brown reported consulting for Janssen, Gilead, Celgene, Sun BioPharma, Novartis, AbbVie, Pfizer, AstraZeneca, Astellas, RedX, Pharmacyclics, Genentech/Roche, Verastem, and TG Therapeutics, and grants from Gilead and Sun BioPharma.

The US Food and Drug Administration (FDA) has approved brentuximab vedotin (ADCETRIS) in combination with chemotherapy for adults with previously untreated, stage III or IV classical Hodgkin lymphoma (cHL).

This is the fifth approved indication for BV in the US and the first regimen approved for frontline, stage III/IV cHL in the US in more than 40 years.

“The standard of care for treating newly diagnosed, advanced Hodgkin lymphoma has not changed in more than 4 decades,” said Joseph M. Connors, MD, of BC Cancer in Vancouver, British Columbia, Canada.

“For years, the physician community has been conducting clinical trials to identify improved regimens that are both less toxic and more effective—to no avail.”

The ECHELON-1 study changed that, according to Dr Connors.

“The ECHELON-1 study results demonstrated superior efficacy of the ADCETRIS plus chemotherapy regimen, when compared to the standard of care, while removing bleomycin—an agent that can cause unpredictable and sometimes fatal lung toxicity—completely from the regimen,” he said. “This represents a meaningful advance for this often younger patient population.”

In the phase 3 ECHELON-1 trial, researchers compared BV plus doxorubicin, vinblastine, and dacarbazine (A+AVD) to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD).

In addition to supporting the new approval for BV in cHL, ECHELON-1 results also served to convert an accelerated approval of BV to standard approval. The drug now has standard FDA approval for the treatment of adults with systemic anaplastic large-cell lymphoma (ALCL) who have failed at least 1 prior multi-agent chemotherapy regimen.

BV also has standard FDA approval for:

• Adults with cHL who have failed autologous hematopoietic stem cell transplant (auto-HSCT) or, in those who are not auto-HSCT candidates, have failed at least 2 prior multi-agent chemotherapy regimens
• Post-auto-HSCT consolidation in adults with cHL at high risk of relapse or progression
• Adults with primary cutaneous ALCL or CD30-expressing mycosis fungoides who have received prior systemic therapy.

ECHELON-1

Result from ECHELON-1 were presented at the 2017 ASH Annual Meeting and simultaneously published in NEJM.

In this trial, researchers compared A+AVD to ABVD as frontline treatment for 1334 patients with advanced cHL. The primary endpoint was modified progression-free survival (PFS), which was defined as time to progression, death, or evidence of non-complete response after completion of frontline therapy followed by subsequent anticancer therapy.

According to an independent review facility, A+AVD provided a significant improvement in modified PFS compared to ABVD. The hazard ratio was 0.77 (P=0.035), which corresponds to a 23% reduction in the risk of progression, death, or the need for additional anticancer therapy.

The 2-year modified PFS rate was 82.1% in the A+AVD arm and 77.2% in the ABVD arm.

There was no significant difference between the treatment arms when it came to response rates or overall survival.

The objective response rate was 86% in the A+AVD arm and 83% in the ABVD arm (P=0.12). The complete response rate was 73% and 70%, respectively (P=0.22).

The interim 2-year overall survival rate was 97% in the A+AVD arm and 95% in the ABVD arm (hazard ratio=0.72; P=0.19).

The overall incidence of adverse events (AEs) was 99% in the A+AVD arm and 98% in the ABVD arm. The incidence of grade 3 or higher AEs was 83% and 66%, respectively, and the incidence of serious AEs was 43% and 27%, respectively.

Neutropenia, febrile neutropenia, and peripheral neuropathy were more common with A+AVD, while pulmonary toxicity was more common with ABVD.

In the phase 3 ECHELON-1 trial, researchers compared BV plus doxorubicin, vinblastine, and dacarbazine (A+AVD) to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD).

In addition to supporting the new approval for BV in cHL, ECHELON-1 results also served to convert an accelerated approval of BV to standard approval. The drug now has standard FDA approval for the treatment of adults with systemic anaplastic large-cell lymphoma (ALCL) who have failed at least 1 prior multi-agent chemotherapy regimen.

BV also has standard FDA approval for:

• Adults with cHL who have failed autologous hematopoietic stem cell transplant (auto-HSCT) or, in those who are not auto-HSCT candidates, have failed at least 2 prior multi-agent chemotherapy regimens
• Post-auto-HSCT consolidation in adults with cHL at high risk of relapse or progression
• Adults with primary cutaneous ALCL or CD30-expressing mycosis fungoides who have received prior systemic therapy.

ECHELON-1

Result from ECHELON-1 were presented at the 2017 ASH Annual Meeting and simultaneously published in NEJM.

In this trial, researchers compared A+AVD to ABVD as frontline treatment for 1334 patients with advanced cHL. The primary endpoint was modified progression-free survival (PFS), which was defined as time to progression, death, or evidence of non-complete response after completion of frontline therapy followed by subsequent anticancer therapy.

According to an independent review facility, A+AVD provided a significant improvement in modified PFS compared to ABVD. The hazard ratio was 0.77 (P=0.035), which corresponds to a 23% reduction in the risk of progression, death, or the need for additional anticancer therapy.

The 2-year modified PFS rate was 82.1% in the A+AVD arm and 77.2% in the ABVD arm.

There was no significant difference between the treatment arms when it came to response rates or overall survival.

The objective response rate was 86% in the A+AVD arm and 83% in the ABVD arm (P=0.12). The complete response rate was 73% and 70%, respectively (P=0.22).

The interim 2-year overall survival rate was 97% in the A+AVD arm and 95% in the ABVD arm (hazard ratio=0.72; P=0.19).

The overall incidence of adverse events (AEs) was 99% in the A+AVD arm and 98% in the ABVD arm. The incidence of grade 3 or higher AEs was 83% and 66%, respectively, and the incidence of serious AEs was 43% and 27%, respectively.

Neutropenia, febrile neutropenia, and peripheral neuropathy were more common with A+AVD, while pulmonary toxicity was more common with ABVD.

Researchers analyzed peripheral blood T cells from 157 pediatric cancer patients at diagnosis and after chemotherapy and found the potential to produce effective chimeric antigen receptor (CAR) T cells declined with each cycle of chemotherapy.

This was also true for acute lymphoblastic leukemia (ALL) and Wilms’ tumor, which had high CAR T-cell manufacturing potential in the pre-chemotherapy samples.

Children younger than 3 years particularly showed a significant decline in CAR T-cell potential with cumulative cycles of chemotherapy.

“Everybody knows that chemotherapy is really bad for your T cells, and the more chemo you get, the less likely you are to have healthy T cells,” David M. Barrett, MD, PhD, of Children’s Hospital of Philadelphia in Pennsylvania, said at a press preview of research to be presented at the AACR Annual Meeting 2018.

“We know a lot about what a highly active, highly successful CAR T cell looks like right before it goes back into the patient after it’s finished manufacturing,” Dr Barrett added.

But he and his colleagues wanted to determine what goes into producing high-quality cells from a patient and the difference between cells that were good starting material and cells that weren’t.

The investigators analyzed blood samples from pediatric patients with ALL, non-Hodgkin lymphoma, neuroblastoma, osteosarcoma, rhabdomyosarcoma, Wilms’ tumor, Hodgkin lymphoma, chronic myeloid leukemia, and Ewing sarcoma. The team collected samples at diagnosis and after every cycle of chemotherapy.

Using flow cytometry, they quantified the CD3+ cell population and expanded the T cells using CD3 and CD28 stimulatory beads, “the backbone of pretty much every center’s way to make CAR T cells in the lab,” Dr Barrett said.

And the researchers found poor CAR T-cell manufacturing potential in all tumor types at diagnosis except for ALL and Wilms’ tumor. In standard-risk and high-risk ALL, more than 90% of patients had high-quality T cells at diagnosis.

The team report the findings in abstract 1631, which is scheduled to be presented at the AACR Annual Meeting on April 15.

“This may have played into why pediatric ALL is one of the great successes with CAR T-cell therapy,” Dr Barrett explained. “We may have actually been working with uniquely well-suited, good starting material to build a CAR T cell.”

T cells from lymphoma patients—Burkitt lymphoma, diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, and Hodgkin lymphoma—were actually quite poor in their potential to become good CAR T cells, Dr Barrett noted.

“This may be reflected clinically in pediatrics at Children’s Hospital of Philadelphia,” he said. “We’ve only been able to successfully treat 3 children with lymphoma, as opposed to more than 200 children with leukemia.”

The only other type of tumor that seemed to have good CAR T potential was Wilms’ tumor.

“I don’t have a CAR T cell for Wilms’ tumor yet,” Dr Barrett said, “but, if I wanted to make one, I would at least have a degree of confidence that the cells gotten from a patient would at least be able to be successfully made into a highly functional T cell that can go back into a patient.”

The investigators also observed that cumulative chemotherapy alters the metabolic profile in T cells, “gradually turning them by cycle 6 into something that doesn’t work anymore,” Dr Barrett said.

The researchers then looked into what differences there were in the quality of collected T cells and found that metabolic changes varied with tumor and treatment.

T cells with poor CAR T-cell potential were biased toward using glycolysis as their energy source instead of using fatty acids.

“Normal, healthy donor T cells cluster together in terms of metabolic pathways that are active or inactive,” Dr Barrett explained.

“[P]atients who had leukemia and the Wilms’ tumor patients could make successful CAR T cells from those samples. On the other hand, solid tumors and a Hodgkin disease patient look like they have a very different metabolic profile. And that is associated with failure to make a good CAR T cell.”

The investigators were able to get the T cells to shift metabolic pathways by “essentially force-feeding T cells things like fatty acids so they don’t use as much glucose,” Dr Barrett said.

“We’ve had some success in force-feeding them essentially neutral amino acids and others like arginine. And so you can actually potentially provide a T cell with an attractive alternative fuel source.”

Dr Barrett noted that the findings have already altered practice for children at his institution.

They now collect T cells early even if the patient is not eligible for a CAR trial, “simply because we know that cumulative chemotherapy is going to progressively deteriorate the likelihood that those cells will make a functional CAR product, and we’ve been recommending that to other centers,” Dr Barrett said.

“We’re trying to understand what goes into making the best starting material so that we can alter our approaches to make sure that we make a highly functional CAR T-cell product not only for kids with leukemia and CART19, but also potentially for solid tumor CARs as we try to develop those in the future.”

Classic mantle cell lymphoma (cMCL) has long been treated as a uniformly aggressive disease in need of similarly aggressive treatment, but that approach may be leading to overtreatment, according to one expert.

“The cMCL encompasses a broad category of lymphomas with highly variable clinical behaviors. A contemporary categorization of cMCL as a predominantly aggressive entity is misleading, as only an estimated 20% to 25% of patients with cMCL present with a symptomatic or aggressively behaving disease,” Leonid L. Yavorkovsky, MD, PhD, of the Kaiser Permanente San Jose Medical Center (Calif.), wrote in a commentary in JAMA Oncology.

While groups like the National Comprehensive Cancer Network and the European Society for Medical Oncology recommend that only older patients and those with significant comorbidities should be exempted from intensive therapy, Dr. Yavorkovsky said cMCL should be evaluated on an individual basis, looking closely at the prognostic markers Ki-67, SOX-11, and TP53 to identify asymptomatic patients who might be able to safely delay aggressive treatment. He also called for more risk-adapted patient assignment to cMCL clinical trials.

“The failure to recognize the erratic nature of cMCL in clinical studies may confound the outcome gains and, ultimately, undermine the ensuing treatment recommendations,” Dr. Yavorkovsky wrote.

SALT LAKE CITY – Chimeric antigen receptor (CAR) T-cell therapy may be an effective bridge to hematopoietic cell transplant (HCT) for high-risk B-cell malignancies, according to a systematic analysis of patient data from the National Cancer Institute.

Additionally, patients who have received CAR T-cell therapy are likely to enter HCT with a minimal residual disease (MRD)–negative complete response, which raises the possibility of a significantly less intense conditioning regimen that could omit total body irradiation (TBI), Haneen Shalabi, DO, said at the combined annual meetings of the Center for International Blood & Marrow Transplant Research and the American Society for Blood and Marrow Transplantation.

“Patients who underwent HCT post–CAR T therapy did not have increased transplant-related morbidity or mortality,” said Dr. Shalabi, a pediatric oncologist in the hematologic diseases division of the National Cancer Institute’s pediatric oncology branch.

The combined approach also overcomes the frequent relapses seen after CAR T-cell therapy in this population. Of the 45 patients who received CAR T-cell therapy and achieved MRD-negative complete response as measured by flow cytometry, 20 did not go on to receive HCT. Of the 20 who didn’t receive HCT, 16 (80%) relapsed; 19 of the 20 (95%) had received prior HCT, said Dr. Shalabi.

However, of the 25 patients who proceeded on to receive HCT, 15 (60%) were in ongoing remission, with a median duration of 35 months (range, 11-55 months). Six patients (24%) experienced transplant-related mortality; four of these patients had no prior HCT. Ten patients (40%) experienced acute graft-versus-host disease (GVHD); two of these patients experienced grade 4 GVHD, and one experienced grade 3 GVHD.

Of the 25 patients who went on to HCT, 19 were receiving their first transplant, with a median time to transplant after CAR T-cell therapy of 57 days. Five patients (20%) had primary refractory disease. Most patients (n = 18; 72%) had TBI-based conditioning prior to their post–CAR T-cell therapy HCT. The median patient age was 15 (range, 5-30) years.

The systematic review included patients from two phase 1 studies; one was of CD19-28z CAR T-cell therapy for children and young adults with B-cell leukemia or lymphoma, and the other was of CD22-41BB CAR T-cell therapy for children and young adults with recurrent or refractory B-cell malignancies expressing CD22.

To weigh the benefit of the combined CAR T-cell therapy/HCT approach, Dr. Shalabi and her colleagues used a competing risk analysis to determine the risk of relapse post-HCT versus the risk of transplant-related mortality. Among patients undergoing their first HCT, the researchers found a 12-month cumulative incidence of relapse of 5.3% with the combined CAR T-cell therapy/HCT approach (95% confidence interval, 0.3%-22.1%). The 24-month cumulative incidence of relapse was 11.3% (95% CI, 1.7%-31.1%).

ORLANDO—Results of a retrospective study showed that survivors of lymphoma or breast cancer had a significantly greater risk of congestive heart failure (CHF) than patients who did not have cancer.

This increased risk was observed as early as a year after cancer diagnosis but was still present 20 years after diagnosis.

Overall, 1 in 10 cancer patients had CHF at the 20-year mark.

“The majority of patients do not develop heart failure, but our research helps us recognize the factors associated with it and the importance of appropriate heart care following cancer treatment,” said Carolyn Larsen, MD, of the Mayo Clinic in Rochester, Minnesota.

“Our research suggests that periodic cardiac imaging to monitor for heart damage may be needed for some cancer patients, even if they have no signs of heart damage initially after chemotherapy. Additionally, it emphasizes that working to live a heart-healthy lifestyle is important for cancer patients and survivors to reduce the overall risk of heart disease.”

Dr Larsen and her colleagues presented this research as a poster (abstract 1105-066) at the American College of Cardiology’s 67th Annual Scientific Session & Expo (ACC.18).

Patients

Using data from the Rochester Epidemiology Project, the researchers retrospectively tracked CHF cases in 900 cancer patients and 1550 non-cancer patients. Patients were treated in Olmsted County in Minnesota from 1985 to 2010.

For both patient groups, the median age at baseline was about 53, a little more than 90% of each group was white, and nearly 80% of each group was female.

Six to 7% of patients had diabetes, and about 30% of each group had hypertension. Thirty-eight percent of each group had hyperlipidemia, and 31% were obese.

Five percent of cancer patients and 2% of controls had coronary artery disease (P<0.001). This was the only significant difference in baseline characteristics.

Cancer patients had been diagnosed with non-Hodgkin lymphoma (28%), Hodgkin lymphoma (9%), or breast cancer (64%). Forty-seven percent had received radiation, including right chest (21%), left chest (23%), and mediastinal (4%).

Eighty-four percent of patients had received anthracycline therapy. The median doxorubicin isotoxic dose was 240 mg/m².

At baseline, 12% of cancer patients were on beta-blockers, 8% were on angiotensin converting enzyme inhibitors, 4% were on angiotensin receptor blockers, and 11% were on statins.

Cancer patients were more than 3 times as likely as controls to develop CHF. The hazard ratio (HR) was 3.6 (P<0.01) in an analysis adjusted for age, gender, diabetes, hypertension, coronary artery disease, dyslipidemia, and obesity at baseline.

The increased CHF risk among cancer patients was evident after the first year from cancer diagnosis and persisted at 20 years of follow-up.

“The risk of heart failure doesn’t go away after a couple of years,” Dr Larsen said. “It’s a long-term issue that patients need to discuss with their doctors and use as motivation to stay heart healthy.”

The incidence of CHF—in cancer patients and controls, respectively—was as follows:

• 1 year—1.5% vs 0.1%
• 5 years—3.1% vs 0.9%
• 10 years—5.0% vs 2%
• 20 years—10.1% vs 5.8%.

A multivariable analysis in the cancer patients revealed a few independent risk factors for CHF, including:

• Doxorubicin isotoxic dose ≥ 300 mg/m² (HR=2.34, P=0.003)
• Age at diagnosis (HR=3.06 for age ≥ 80 vs 60-69, P=0.01)
• Coronary artery disease at diagnosis (HR=2.27, P=0.04)
• Diabetes mellitus at diagnosis (HR=2.39, P<0.01).

Dr Larsen said additional research is needed to determine why diabetes carries a greater risk than other traditional risk factors, such as high blood pressure, in this group.

Mitigating risk

These findings raise important questions about what the appropriate surveillance should be for heart problems post-cancer treatment, Dr Larsen said. She believes more frequent cardiac imaging may be warranted in some patients to detect signs of CHF earlier.

“It’s an area that needs to be better defined,” Dr Larsen said. “An echocardiogram is usually done 6 to 12 months after cancer treatment with an anthracycline, but how often should it be done after that? We need to be more vigilant in making sure we try to prevent or control heart issues post-cancer care, especially in light of the growing appreciation of the connection between some cancer treatments and heart disease.”

Dr Larsen also noted that patients themselves can play a role in decreasing their risk of CHF, even if they are starting at a disadvantage.

A heart-healthy lifestyle—maintaining a normal body weight, regular exercise, and controlling other risk factors such as high blood pressure, diabetes, and high cholesterol—can help lower the risk of heart disease and CHF.

“If patients know they have received a drug treatment that might increase their risk of heart failure, it’s even more important to take care of the aspects of their life that they can control to reduce their risk as much as possible and to work with their medical care team to detect issues as early as possible,” Dr Larsen said.

ORLANDO—Results of a retrospective study showed that survivors of lymphoma or breast cancer had a significantly greater risk of congestive heart failure (CHF) than patients who did not have cancer.

This increased risk was observed as early as a year after cancer diagnosis but was still present 20 years after diagnosis.

Overall, 1 in 10 cancer patients had CHF at the 20-year mark.

“The majority of patients do not develop heart failure, but our research helps us recognize the factors associated with it and the importance of appropriate heart care following cancer treatment,” said Carolyn Larsen, MD, of the Mayo Clinic in Rochester, Minnesota.

“Our research suggests that periodic cardiac imaging to monitor for heart damage may be needed for some cancer patients, even if they have no signs of heart damage initially after chemotherapy. Additionally, it emphasizes that working to live a heart-healthy lifestyle is important for cancer patients and survivors to reduce the overall risk of heart disease.”

Dr Larsen and her colleagues presented this research as a poster (abstract 1105-066) at the American College of Cardiology’s 67th Annual Scientific Session & Expo (ACC.18).

Patients

Using data from the Rochester Epidemiology Project, the researchers retrospectively tracked CHF cases in 900 cancer patients and 1550 non-cancer patients. Patients were treated in Olmsted County in Minnesota from 1985 to 2010.

For both patient groups, the median age at baseline was about 53, a little more than 90% of each group was white, and nearly 80% of each group was female.

Six to 7% of patients had diabetes, and about 30% of each group had hypertension. Thirty-eight percent of each group had hyperlipidemia, and 31% were obese.

Five percent of cancer patients and 2% of controls had coronary artery disease (P<0.001). This was the only significant difference in baseline characteristics.

Cancer patients had been diagnosed with non-Hodgkin lymphoma (28%), Hodgkin lymphoma (9%), or breast cancer (64%). Forty-seven percent had received radiation, including right chest (21%), left chest (23%), and mediastinal (4%).

Eighty-four percent of patients had received anthracycline therapy. The median doxorubicin isotoxic dose was 240 mg/m².

At baseline, 12% of cancer patients were on beta-blockers, 8% were on angiotensin converting enzyme inhibitors, 4% were on angiotensin receptor blockers, and 11% were on statins.

SALT LAKE CITY – A CD19-directed 4-1BB chimeric antigen receptor (CAR) T cell product showed efficacy and a low rate of cytokine release syndrome and neurotoxicity in patients with aggressive lymphomas and poor prognoses, raising the possibility of outpatient administration and fewer hospitalization days in this high-risk group.

A total of 86 patients who received inpatient infusions of lisocabtagene maraleucel (liso-cel, also known as JCAR017) had a mean 15.6 days of hospitalization, compared with 9.3 days for 8 outpatient recipients, said Jeremy Abramson, MD, speaking at a top abstracts session of the combined annual meetings of the Center for International Blood & Marrow Transplant Research and the American Society for Blood and Marrow Transplantation.

Although all but one required hospital admission, at a median of 5 days postinfusion (range, 4-22 days), there had been no intensive care unit admissions, and no outpatient recipients had experienced severe cytokine release syndrome (CRS) or neurotoxicity. All admitted patients presented with fever.

Among the study population, “Cytokine release syndrome was only seen in 35% of our entire dataset,” with neurologic toxicity seen in 19% of participants, Dr. Abramson said. “The majority of subjects had no CRS and no toxicity,” he said. Severe CRS occurred in 1% of the study population, and severe neurotoxicity in 12%. There were no deaths related to either complication.

Dr. Abramson reported these results from the TRANSCEND NHL 001 trial, a seamless design phase 1 pivotal trial of liso-cel enrolling patients with relapsed and refractory aggressive B cell non-Hodgkin lymphoma (NHL). Liso-cel delivers CD19-directed CD4 and CD8 CAR T cells in a 1:1 ratio, said Dr. Abramson, director of the lymphoma program at the Massachusetts General Hospital Cancer Center, Boston.

A total of 91 patients were randomized to one of the three dose-finding cohorts of the multicenter trial of liso-cel. One cohort received 5 x 10⁷ cells in a single dose; a second cohort received the same number of cells but in two doses administered 14 days apart; the third cohort received a single dose of 1 x 10⁸ cells.

The seamless trial design then moved to dose expansion, using the two single doses established in the dose-finding phase of the study. Ultimately, Dr. Abramson said, the third and pivotal diffuse large B-cell lymphoma (DLBCL) cohort received the higher single dose, since a dose-response relationship was seen in the earlier cohorts. No increase in cytokine release syndrome or neurotoxicity has been seen with the higher dose in patients evaluated to date.

Patients (median age, 61 years) were eligible to participate in the trial if they had relapsed or refractory DLBCL, primary mediastinal B-cell lymphoma, grade 3B follicular lymphoma, or mantle cell lymphoma. Patients with a failed prior allogeneic stem cell transplant or secondary central nervous system involvement were eligible, but all patients had to have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.

As the trial moved to the core pivotal phase, eligibility requirements shifted slightly to include patients with ECOG status 0 or 1, and lymphoma diagnoses narrowed to include only DLBCL not otherwise specified (NOS), transformed follicular lymphoma, and high-grade B-cell lymphoma with double- and triple-hit cytogenetics. The core group was nearing completion of accrual at the time of the presentation, which presented preliminary results from this phase of the trial.

Among the 88 evaluable patients in the initial population with DLBCL receiving any of three dose levels, the best overall response rate (ORR) was 74% (95% confidence interval, 63%-83%); 52% of these patients achieved complete response (CR; 95% CI, 41%-63%).

For patients receiving the higher dose of liso-cel, the ORR was 81% (95% CI, 62%-94%), with a 63% CR rate (95% CI, 42%-81%), bearing out the dose-response rate that had been seen earlier in the trial, Dr. Abramson said.

The median duration of response in all TRANSCEND patients was 9.2 months; the median duration of remission has not been reached, he said. “We see evidence of durable response at 3 months in all our high-risk subsets, and that includes double- and triple-hit lymphomas, double-expresser lymphomas, patients who’ve never achieved prior complete remission, and patients with refractory disease.”

“The overall results are similarly encouraging,” Dr. Abramson said, with 86% of all patients alive at 6 months. Among the complete responders, 94% are alive at the 6-month mark. “The median duration of complete responders has not been reached in this cohort,” he said.

These results are notable, Dr. Abramson said, since about 90% of study participants have at least one disease risk factor that would predict median overall survival of 3-6 months.

LA JOLLA, CALIF. – When patients with peripheral T-cell lymphoma (PTCL) experience relapse, consider an allogeneic stem cell transplant or clinical trial, investigators advised.

Patients with relapsed PTCL have generally dismal outcomes, with a median progression-free survival (PFS) of 3.7 months and a median overall survival (OS) of just 6.5 months, according to one study (J Clin Oncol. 2013 Jun 1;31[16]:1970-6).

She outlined her center’s approach for treating patients with relapsed or refractory PTCL, following a case presentation by Royal Marsden fellow Matthew Cross, MD.

Complex disease, multiple therapies

The patient was a 71-year-old woman who in 2007 had a diagnosis of asymptomatic stage 4A follicular lymphoma managed with observation; in 2010, she was diagnosed with a CD30-positive PTCL not otherwise specified with ongoing low-level bone marrow involvement with follicular lymphoma.

She initially was treated elsewhere with R-CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) and had a response after four cycles; however, she had progression with new intra-abdominal nodal sites by the sixth cycle and then was started on two cycles of ESHAP (etoposide, methylprednisolone, high-dose cytarabine, and cisplatin), but she had further progression by May 2011 and opted to forgo additional treatment.

By July 2011, however, she became highly symptomatic with new pruritic rashes on her legs, abdominal pain, and distention. She was referred to the Royal Marsden Hospital, where she was eventually diagnosed with angioimmunoblastic T-cell lymphoma (AITL) with an Epstein-Barr virus–negative clonal large B-cell proliferation in her bone marrow.

She was treated with gemcitabine plus methylprednisolone and prophylactic intrathecal methotrexate and had an “excellent clinical and radiological response,” Dr. Cross said.

A subsequent bone marrow biopsy showed marked hypocellularity but no evidence of either T-cell of B-cell lymphomas.

An autologous stem cell transplant was planned, but two attempts at harvesting peripheral blood stem cells – including one with plerixafor (Mozobil) – failed, and a PET scan within 3 months showed signs of early progression.

In April 2012, the patient was started on romidepsin (Istodax) and had a 1-year remission. But in April 2013, a repeat biopsy again showed CD30-positive AITL. Based on the CD30 positivity, the patient was started on brentuximab vedotin (Adcetris) in May 2013. She was observed to have progression in inguinal nodes in January 2014; she was treated with local radiotherapy and continued on brentuximab but had further progression in June 2014. At that time, she had additional gemcitabine-based combination chemotherapy and had stable disease for 10 months.

In March 2015, she received lenalidomide for further progression but could not tolerate the drug. She died in September 2015, 5 years after diagnosis and 4.5 years after frontline therapy failed.

Therapeutic rationale

Dr. Dearden walked through the choices that she, along with Dr. Cross and their colleagues, made in treating the patient. They chose gemcitabine-based regimens for salvage therapy because of the drug’s efficacy across various forms on non-Hodgkin and Hodgkin lymphoma, she said.

However, a randomized, phase 3, noninferiority trial in the United Kingdom comparing GEM-P (gemcitabine, cisplatin, and methylprednisolone) with CHOP for first-line therapy of PTCL was halted at the interim analysis because GEM-P had not meet the primary endpoint, she said. Results of that trial have not been published to date.

“Clearly, if it’s the patients who do well, often it’s because they achieve a good enough remission to be able to proceed to some sort of consolidation therapy with autologous or allogeneic stem cell transplants, and I think auto-graft is probably accepted for the younger, fitter patients with relapsed chemo-sensitive disease,” she said.

Three-year survival rates for autologous hematopoietic stem cell transplantation range from 36% to 58% and are better than those seen with chemotherapy alone, she said.

“The problem of course is that not many patients receive the planned auto-graft, even if that’s the intention, either because of failure to respond to salvage regimen or early disease progression, which happens before the transplant is able to take place,” she said,

A reasonable alternative for patients with relapsed/refractory PTCL is allogeneic transplantation, as shown in a 2008 study.

Among 77 patients – 57 of whom had received myeloablative conditioning, 31 of whom were in complete remission, and 26 of whom had partial response at the time of transplants – the 5-year treatment-related mortality rate was 33%. However, the 5-year event-free and overall survival rates were 53% and 57%, respectively. Patients with AITL had especially good outcomes (J Clin Oncol. 2008 May 10;26[14]:2264-71).

“In an ideal world, if our patient had been a suitable candidate for an allo-transplant, it’s what we would have tried to undertake,” Dr. Dearden said.

Dr. Dearden recommended that all patients with relapsed or refractory PTCL be considered for clinical trials. For fit patients in first relapse, combination platinum-based chemotherapy followed by autologous or allogeneic transplant may be effective.

For patients not eligible for transplant or with chemotherapy-refractory disease, she recommended trying the following monotherapy approaches: pralatrexate for patients with PTCL not otherwise specified, histone deacetylase inhibitors or 5-azacytidine for AITL, brentuximab vedotin for anaplastic large cell lymphoma, and pembrolizumab for natural killer/T-cell lymphomas.

Although two lines of intensive chemotherapy had failed the case patient within 6 months of diagnosis, she still survived for 5 years with sequential monotherapies, Dr. Dearden noted.

“I use to say to her, ‘You just need to stay one drug ahead of your disease.’ And she was well, she had a very good quality of life for a period of time, and if you can deliver a treatment that is effective for a patient, it will extend their survival,” Dr. Dearden said.

LA JOLLA, CALIF. – When patients with peripheral T-cell lymphoma (PTCL) experience relapse, consider an allogeneic stem cell transplant or clinical trial, investigators advised.

Patients with relapsed PTCL have generally dismal outcomes, with a median progression-free survival (PFS) of 3.7 months and a median overall survival (OS) of just 6.5 months, according to one study (J Clin Oncol. 2013 Jun 1;31[16]:1970-6).

She outlined her center’s approach for treating patients with relapsed or refractory PTCL, following a case presentation by Royal Marsden fellow Matthew Cross, MD.

Complex disease, multiple therapies

The patient was a 71-year-old woman who in 2007 had a diagnosis of asymptomatic stage 4A follicular lymphoma managed with observation; in 2010, she was diagnosed with a CD30-positive PTCL not otherwise specified with ongoing low-level bone marrow involvement with follicular lymphoma.

She initially was treated elsewhere with R-CHOP chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) and had a response after four cycles; however, she had progression with new intra-abdominal nodal sites by the sixth cycle and then was started on two cycles of ESHAP (etoposide, methylprednisolone, high-dose cytarabine, and cisplatin), but she had further progression by May 2011 and opted to forgo additional treatment.

By July 2011, however, she became highly symptomatic with new pruritic rashes on her legs, abdominal pain, and distention. She was referred to the Royal Marsden Hospital, where she was eventually diagnosed with angioimmunoblastic T-cell lymphoma (AITL) with an Epstein-Barr virus–negative clonal large B-cell proliferation in her bone marrow.

She was treated with gemcitabine plus methylprednisolone and prophylactic intrathecal methotrexate and had an “excellent clinical and radiological response,” Dr. Cross said.

A subsequent bone marrow biopsy showed marked hypocellularity but no evidence of either T-cell of B-cell lymphomas.

An autologous stem cell transplant was planned, but two attempts at harvesting peripheral blood stem cells – including one with plerixafor (Mozobil) – failed, and a PET scan within 3 months showed signs of early progression.

In April 2012, the patient was started on romidepsin (Istodax) and had a 1-year remission. But in April 2013, a repeat biopsy again showed CD30-positive AITL. Based on the CD30 positivity, the patient was started on brentuximab vedotin (Adcetris) in May 2013. She was observed to have progression in inguinal nodes in January 2014; she was treated with local radiotherapy and continued on brentuximab but had further progression in June 2014. At that time, she had additional gemcitabine-based combination chemotherapy and had stable disease for 10 months.

In March 2015, she received lenalidomide for further progression but could not tolerate the drug. She died in September 2015, 5 years after diagnosis and 4.5 years after frontline therapy failed.

Therapeutic rationale

Dr. Dearden walked through the choices that she, along with Dr. Cross and their colleagues, made in treating the patient. They chose gemcitabine-based regimens for salvage therapy because of the drug’s efficacy across various forms on non-Hodgkin and Hodgkin lymphoma, she said.

However, a randomized, phase 3, noninferiority trial in the United Kingdom comparing GEM-P (gemcitabine, cisplatin, and methylprednisolone) with CHOP for first-line therapy of PTCL was halted at the interim analysis because GEM-P had not meet the primary endpoint, she said. Results of that trial have not been published to date.

“Clearly, if it’s the patients who do well, often it’s because they achieve a good enough remission to be able to proceed to some sort of consolidation therapy with autologous or allogeneic stem cell transplants, and I think auto-graft is probably accepted for the younger, fitter patients with relapsed chemo-sensitive disease,” she said.

Three-year survival rates for autologous hematopoietic stem cell transplantation range from 36% to 58% and are better than those seen with chemotherapy alone, she said.

“The problem of course is that not many patients receive the planned auto-graft, even if that’s the intention, either because of failure to respond to salvage regimen or early disease progression, which happens before the transplant is able to take place,” she said,

A reasonable alternative for patients with relapsed/refractory PTCL is allogeneic transplantation, as shown in a 2008 study.

Among 77 patients – 57 of whom had received myeloablative conditioning, 31 of whom were in complete remission, and 26 of whom had partial response at the time of transplants – the 5-year treatment-related mortality rate was 33%. However, the 5-year event-free and overall survival rates were 53% and 57%, respectively. Patients with AITL had especially good outcomes (J Clin Oncol. 2008 May 10;26[14]:2264-71).

“In an ideal world, if our patient had been a suitable candidate for an allo-transplant, it’s what we would have tried to undertake,” Dr. Dearden said.

Variations in the clinical presentation of immunotherapy-induced inflammatory arthritis is partly explained by which treatment regimen was used to treat the cancer, a single-center study suggests.

While immune checkpoint inhibitors (ICI) have revolutionized the field of oncology, their use for an ever-widening range of indications had created an increasing population of patients referred to rheumatologists for the management of immune-related adverse events (IrAEs), according to Laura C. Cappelli, MD, and her colleagues at John Hopkins University, Baltimore. 

Well-established guidelines exist for managing adverse events such as colitis and pneumonitis, but there are only preliminary guidelines for evaluating and treating immunotherapy-induced inflammatory arthritis (IA). “This may stem from a lack of consistent reporting of rheumatologic IrAEs in clinical trials, the non–life threatening nature of [inflammatory arthritis], or lack of recognition of musculoskeletal symptoms by treating providers,” they wrote in Seminars in Arthritis and Rheumatism.

Clinical trials have reported ranges of arthralgia in 1%-43% of patients treated with ICIs, but no accurate estimate of the incidence of IA exists. 

The researchers noted that treating patients with ICI-induced IA is complicated by a history of active or recently treated cancer and concerns over using immunosuppression in the context of ICI therapy. 

They set out to evaluate the clinical presentations of 30 patients seen in their clinic with ICI-induced IA. Patients were a median of 59 years old and 12 (40%) were female. Tumor types included metastatic melanoma, non–small cell lung cancer, small cell lung cancer, colorectal cancer, Hodgkin lymphoma, cutaneous lymphoma, renal cell carcinoma, duodenal carcinoma, Merkel cell carcinoma, cutaneous basal cell carcinoma, and cutaneous squamous cell carcinoma.

Sixteen patients were treated with anti–programmed cell death protein 1 (PD-1)/programmed death ligand 1 monotherapy, and 14 were treated with combination anti–CTLA-4/PD-1 therapy. 
Patients on combination therapy were significantly younger (7.5 years, P = 0.01) and were more likely to have metastatic melanoma as their underlying cancer.

Patients who received combination therapy were more likely to present first with knee IA (n = 10) and none had small joint involvement. In contrast, initial small joint involvement was more common in the monotherapy group (n = 6).

Most of the patients in the study had an additional IrAE, with colitis being the most common (n=10), followed by thyroid disease, pneumonitis, and rash. Patients on PD-1 or programmed death ligand 1 monotherapy were more likely to have IA as their first IrAE.

The research team noted that the median time to symptom onset was 5 months after ICI initiation.

Diagnosis of IA following patient-reported symptoms was an average of 5.2 months, with a significant difference in lag time to diagnosis depending on initial joint presentation. For example, patients with initial small joint involvement had a 10 month longer lag time to IA diagnosis than those with knees as the initial joint involved. 

In terms of treatment, 24 patients were treated with systemic corticosteroids and 10 required additional immunosuppression. The need for corticosteroids did not differ by ICI treatment regimen, but those treated with combination therapy were more likely to require additional immunosuppression (P = 0.02).

Tumor necrosis factor inhibitors with or without methotrexate were prescribed for seven patients. All of the patients had a clinical improvement in their arthritis symptoms. Four had a complete tumor response at the time of tumor necrosis factor inhibitor initiation with none having tumor progression.

The three patients treated with methotrexate monotherapy had a complete or sustained partial tumor response to ICI therapy and their cancer did not develop during IA management follow-up.  

The authors went on to look at the persistence of IA after cessation of therapy in a subset of 21 patients. They found that 18 of these patients still had IA symptoms months after stopping treatment. They suggested that the delay in diagnosis and treatment seen in their study might explain the finding. 

The study provides “critical information, not just for rheumatologists as they try to recognize subgroups in ICI-induced IA and diagnose patients with this new entity, but also for oncology providers who are usually first to encounter patients with ICI-induced IA and subsequently refer patients to rheumatology,” Dr. Cappelli and colleagues wrote.

The experience so far with using immunosuppression in ICI-induced IA “has been reassuring in terms of cancer outcomes, but more studies are needed to confirm this finding,” they concluded.
