Hodgkin Lymphoma

Obinutuzumab and bendamustine followed by obinutuzumab maintenance therapy was superior to bendamustine monotherapy based on progression-free survival in rituximab-refractory patients with indolent non-Hodgkin lymphoma, based on a study published online in the Lancet Oncology.

After a median follow-up of 22 months in the obinutuzumab plus bendamustine group and 20 months in the bendamustine monotherapy group, progression-free survival was significantly longer with obinutuzumab plus bendamustine (median not reached; 95% confidence interval, 22.5 months – not estimable) than with bendamustine monotherapy (14.9 months, range, 12.8-16.6; hazard ratio, 0.55; 95% CI 0.40-0.74; P = .0001). About two-thirds of the nearly 400 patients in both study arms had grade 3-5 adverse events.

The anti-CD20 monoclonal antibody obinutuzumab is an option when patients with indolent non-Hodgkin lymphoma relapse or don’t achieve adequate disease control with rituximab-based treatment, wrote Laurie H. Sehn, MD, of the British Columbia Cancer Agency and the University of British Columbia, Vancouver, and her colleagues.

In an open-label, randomized, phase III study called GADOLIN, patients with CD20-positive indolent non-Hodgkin lymphoma were stratified by indolent non-Hodgkin lymphoma subtype, rituximab-refractory type, number of previous therapies, and geographic region.

For the study, 194 patients were assigned to obinutuzumab plus bendamustine and 202 to bendamustine monotherapy. Trial participants received six 28-day cycles with either obinutuzumab plus bendamustine (obinutuzumab 1,000 mg on days 1, 8, and 15, cycle 1; and on day 1, cycles 2-6) plus bendamustine (90 mg/m² per day on days 1 and 2, cycles 1-6) or bendamustine monotherapy (120 mg/m² per day on days 1 and 2 of all cycles). Patients in the obinutuzumab plus bendamustine group whose disease did not progress received obinutuzumab maintenance therapy of 1,000 mg once every 2 months for up to 2 years.

Grade 3-5 adverse events occurred in 68% of 194 patients in the obinutuzumab plus bendamustine group and in 62% of 198 patients in the bendamustine monotherapy group. Grade 3 or worse neutropenia affected 33% of the obinutuzumab plus bendamustine group and 26% of the bendamustine monotherapy group. Other grade 3 or worse events included thrombocytopenia in 11% and 16%, anemia in 8% and 10%, and infusion-related reactions in 11% and 6%. Serious adverse events occurred in 38% in the obinutuzumab plus bendamustine group and in 33% in the bendamustine monotherapy group. Adverse events resulted in death in 6% of patients in each group.

The study was funded by Hoffmann-La Roche. Genentech, the maker of obinutuzumab (Gazyva) in the United States, is a wholly owned member of the Roche Group. Dr. Sehn receives honoraria and is a consultant or advisor to Genentech as well as several other drug companies.

PET-CT scanner

The use of interim PET-CT scans can spare some advanced Hodgkin lymphoma (HL) patients the toxicity associated with bleomycin, according to researchers.

The team found that patients with negative PET-CT scans after 2 cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) could go on to receive AVD (doxorubicin, vinblastine, and dacarbazine) without experiencing a significant decrease in progression-free survival (PFS) or overall survival (OS).

Peter Johnson, MD, of the University of Southampton in the UK, and his colleagues reported these findings in NEJM.

“The good news is that the majority of people diagnosed with Hodgkin lymphoma can be cured,” Dr Johnson said. “In this trial, more than 95% of patients are alive after 3 years.”

“But we worry about the long-term side effects from the treatments we use. As we’ve done in this trial, personalizing treatment based on how well it works is a major development for patients with Hodgkin lymphoma and sets a new standard of care.”

Patients and treatment

For this study, Dr Johnson and his colleagues enrolled 1214 patients with newly diagnosed, advanced, classic HL. The patients’ median age was 33 (range, 18 to 79), and 54.5% were male. More patients had stage II disease (41.6%) than stage III (30.2%) or IV (28.3%).

A total of 1119 patients underwent a baseline PET-CT scan, received 2 cycles of ABVD, and underwent an interim PET-CT scan.

The patients with negative interim scans were then randomized to continue treatment with ABVD (n=470) or with AVD (n=465) in cycles 3 through 6.

Patients with positive interim scans (n=182) went on to receive BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone, n=172), salvage treatments (n=6), or ABVD (n=4).

Results

The study’s primary outcome was the difference in 3-year PFS between the randomized groups of PET-CT-negative patients.

With a median follow-up of 41 months, the 3-year PFS was 85.7% in the ABVD group and 84.4% in the AVD group. The hazard ratio was 1.13 (95% CI, 0.81 to 1.57; P=0.48) in the intention-to-treat analysis and 1.10 (95% CI, 0.79 to 1.53; P=0.58) in the per-protocol analysis.

The absolute difference in 3-year PFS (ABVD minus AVD) was 1.6 percentage points (95% CI, −3.2 to 5.3).

The OS rates were 97.2% in the ABVD group and 97.6% in the AVD group. The hazard ratio in the intention-to-treat analysis was 0.90 (95% CI, 0.47 to 1.74; P=0.76).

Patients in the ABVD group had a significantly higher rate of clinical adverse events than patients in the AVD group—31% and 21%, respectively (P<0.005).

Patients in the ABVD group also had significantly (P<0.05) higher rates of fatigue (3% vs 1%), febrile neutropenia (5% vs 2%), pulmonary/upper respiratory events (3% vs 1%), and dyspnea (2% vs <0.5%). But patients in the AVD group had a significantly higher rate of thrombocytopenia (3% vs 1%).

For patients who had positive interim PET-CT scans, the 3-year PFS was 67.5%, and the OS was 87.8%. Among the 172 patients who went on to receive BEACOPP, 74.4% had negative findings on a third PET-CT scan.

Overall, 62 patients died during the trial—24 from HL. So, for the entire study cohort, the 3-year PFS was 82.6%, and the OS was 95.8%.

COPENHAGEN—The PD-1 checkpoint inhibitor nivolumab can address an unmet need in patients with classical Hodgkin lymphoma (cHL) who have progressive or relapsed disease, according to a speaker at the 21st Congress of the European Hematology Association.

In the phase 2 Checkmate-205 trial, nivolumab produced an objective response rate of 66% in cHL patients who had relapsed or progressed after autologous hematopoietic stem cell transplant (HSCT) and subsequent brentuximab vedotin.

The median duration of response was 7.8 months, and most patients had a response that was ongoing at the time of analysis.

Although the safety profile of nivolumab was considered “acceptable” by researchers, the drug has been linked to serious complications, including death, among patients who proceeded to allogeneic HSCT after receiving nivolumab.

Still, nivolumab is “an important new therapy to meet the unmet need” in cHL, according to Anas Younes, MD, of Memorial Sloan Kettering Cancer Center in New York, New York.

Dr Younes presented results with nivolumab from cohort B of the Checkmate-205 trial as abstract S793. Checkmate-205 was sponsored by Bristol-Myers Squibb.

Cohort B included 80 cHL patients who had relapsed or progressed after autologous HSCT and post-transplant brentuximab vedotin. (Cohort A included patients who had not previously received brentuximab vedotin.)

The patients’ median age was 37 (range, 18-72), and 64% were male. The median number of prior lines of therapy was 4 (range, 3-15), and 49% of patients had received at least 5 previous lines of therapy.

Seventy-four percent of patients had previously received radiation, 93% had received 1 prior autologous HSCT, and 8% had received 2. All patients had received brentuximab vedotin after transplant, and 54% had not responded to that treatment.

Study treatment

Patients received nivolumab at 3 mg/kg intravenously every 2 weeks until disease progression or unacceptable toxicity.

At a median follow-up of 8.9 months (range, 1.9-11.7), 36% of patients had come off treatment—16% due to disease progression, 5% due to toxicity, 8% because they had gone on to allogeneic HSCT, and 8% for other reasons (the patient’s request, the investigator’s decision, the patient was lost to follow-up, or the reason was not reported).

Dr Younes noted that all patients who stopped nivolumab to undergo HSCT were still alive at the data cut-off.

Efficacy

The objective response rate, per an independent radiologic review committee, was 66%. Nine percent of patients achieved a complete response, 58% had a partial response, 23% had stable disease, and 8% had progressive disease. The committee was unable to determine the status of 4% of patients.

The median time to response was 2.1 months, and the estimated median duration of response was 7.8 months.

“Keep in mind that the majority of patients are still on therapy, so this is expected to improve with time,” Dr Younes said.

The majority of responses (62%) were ongoing at the time of analysis. In an exploratory analysis, the researchers observed that 72% of patients who did not respond to their most recent prior brentuximab vedotin treatment did respond to nivolumab.

At 6 months, the progression-free survival rate was 77%, and the overall survival rate was 99%. The median progression-free survival was 10 months, and the median overall survival has not been reached.

Dr Younes said that, although the follow-up is short, the survival data are “still impressive.”

Safety

Adverse events (AEs) occurred in 99% of patients, grade 3/4 AEs occurred in 40% of patients, and there was 1 grade 5 AE (multi-organ failure due to Epstein-Barr-virus-positive T-cell lymphoma).

Treatment-related AEs occurred in 90% of patients. The most common of these were fatigue (25%), infusion-related reactions (20%), rash (16%), arthralgia (14%), pyrexia (14%), nausea (13%), diarrhea (10%), and pruritus (10%).

Treatment-related serious AEs occurred in 6% of patients and included pyrexia, tumor progression, arrhythmia, infusion reactions, septic meningitis, and pneumonia.

Extended safety follow-up of cHL patients treated in the nivolumab clinical trial program who were subsequently treated with allogeneic HSCT (n=17) revealed complications, including fatal events.

A warning about such complications has been added to the US prescribing information for nivolumab, which was recently granted accelerated approval from the US Food and Drug Administration (FDA) to treat patients with relapsed or refractory cHL who have received an autologous HSCT and post-transplant brentuximab vedotin.

Because of these transplant-related deaths, the FDA has advised that healthcare professionals follow patients closely for early evidence of transplant-related complications, such as hyperacute graft-versus-host disease, severe acute graft-versus-host disease, steroid-requiring febrile syndrome, hepatic veno-occlusive disease, and other immune-mediated adverse reactions.

The FDA has also required that Bristol-Myers Squibb further study the safety of allogeneic HSCT after nivolumab.

COPENHAGEN—The PD-1 checkpoint inhibitor nivolumab can address an unmet need in patients with classical Hodgkin lymphoma (cHL) who have progressive or relapsed disease, according to a speaker at the 21st Congress of the European Hematology Association.

In the phase 2 Checkmate-205 trial, nivolumab produced an objective response rate of 66% in cHL patients who had relapsed or progressed after autologous hematopoietic stem cell transplant (HSCT) and subsequent brentuximab vedotin.

The median duration of response was 7.8 months, and most patients had a response that was ongoing at the time of analysis.

Although the safety profile of nivolumab was considered “acceptable” by researchers, the drug has been linked to serious complications, including death, among patients who proceeded to allogeneic HSCT after receiving nivolumab.

Still, nivolumab is “an important new therapy to meet the unmet need” in cHL, according to Anas Younes, MD, of Memorial Sloan Kettering Cancer Center in New York, New York.

Dr Younes presented results with nivolumab from cohort B of the Checkmate-205 trial as abstract S793. Checkmate-205 was sponsored by Bristol-Myers Squibb.

Cohort B included 80 cHL patients who had relapsed or progressed after autologous HSCT and post-transplant brentuximab vedotin. (Cohort A included patients who had not previously received brentuximab vedotin.)

The patients’ median age was 37 (range, 18-72), and 64% were male. The median number of prior lines of therapy was 4 (range, 3-15), and 49% of patients had received at least 5 previous lines of therapy.

Seventy-four percent of patients had previously received radiation, 93% had received 1 prior autologous HSCT, and 8% had received 2. All patients had received brentuximab vedotin after transplant, and 54% had not responded to that treatment.

Study treatment

Patients received nivolumab at 3 mg/kg intravenously every 2 weeks until disease progression or unacceptable toxicity.

At a median follow-up of 8.9 months (range, 1.9-11.7), 36% of patients had come off treatment—16% due to disease progression, 5% due to toxicity, 8% because they had gone on to allogeneic HSCT, and 8% for other reasons (the patient’s request, the investigator’s decision, the patient was lost to follow-up, or the reason was not reported).

Dr Younes noted that all patients who stopped nivolumab to undergo HSCT were still alive at the data cut-off.

Efficacy

The objective response rate, per an independent radiologic review committee, was 66%. Nine percent of patients achieved a complete response, 58% had a partial response, 23% had stable disease, and 8% had progressive disease. The committee was unable to determine the status of 4% of patients.

The median time to response was 2.1 months, and the estimated median duration of response was 7.8 months.

“Keep in mind that the majority of patients are still on therapy, so this is expected to improve with time,” Dr Younes said.

The majority of responses (62%) were ongoing at the time of analysis. In an exploratory analysis, the researchers observed that 72% of patients who did not respond to their most recent prior brentuximab vedotin treatment did respond to nivolumab.

At 6 months, the progression-free survival rate was 77%, and the overall survival rate was 99%. The median progression-free survival was 10 months, and the median overall survival has not been reached.

Dr Younes said that, although the follow-up is short, the survival data are “still impressive.”

Safety

Adverse events (AEs) occurred in 99% of patients, grade 3/4 AEs occurred in 40% of patients, and there was 1 grade 5 AE (multi-organ failure due to Epstein-Barr-virus-positive T-cell lymphoma).

Treatment-related AEs occurred in 90% of patients. The most common of these were fatigue (25%), infusion-related reactions (20%), rash (16%), arthralgia (14%), pyrexia (14%), nausea (13%), diarrhea (10%), and pruritus (10%).

Treatment-related serious AEs occurred in 6% of patients and included pyrexia, tumor progression, arrhythmia, infusion reactions, septic meningitis, and pneumonia.

Extended safety follow-up of cHL patients treated in the nivolumab clinical trial program who were subsequently treated with allogeneic HSCT (n=17) revealed complications, including fatal events.

A warning about such complications has been added to the US prescribing information for nivolumab, which was recently granted accelerated approval from the US Food and Drug Administration (FDA) to treat patients with relapsed or refractory cHL who have received an autologous HSCT and post-transplant brentuximab vedotin.

Because of these transplant-related deaths, the FDA has advised that healthcare professionals follow patients closely for early evidence of transplant-related complications, such as hyperacute graft-versus-host disease, severe acute graft-versus-host disease, steroid-requiring febrile syndrome, hepatic veno-occlusive disease, and other immune-mediated adverse reactions.

The FDA has also required that Bristol-Myers Squibb further study the safety of allogeneic HSCT after nivolumab.

With the advent of effective anti-retroviral therapy, patients with HIV-related lymphoma receive standard therapeutic regimens and achieve outcomes comparable to those of non-HIV-infected individuals.

Based on results of a multicenter phase 2 study, this now extends to treatment with autologous stem cell transplant (ASCT).

Researchers found that outcomes were not significantly different between HIV-infected patients who received ASCT and matched controls.

“These findings are remarkably important for a group of patients who, up until now, have been inconsistently treated,” said lead study author Joseph C. Alvarnas, MD, of City of Hope National Medical Center in Duarte, California.

“Based on our data, autologous stem cell transplant should be considered the standard of care for patients with HIV-related lymphomas for the same indications and under the same circumstances that we would use it in patients without HIV infection.”

To arrive at this recommendation, investigators enrolled 43 HIV-infected patients with relapsed or persistent non-Hodgkin lymphoma (NHL) or classical Hodgkin lymphoma (HL) onto the Blood and Marrow Transplant Clinical Trials Network (BMT CTN) 0803/AIDS Malignancy Consortium (AMC) 071 study.

They reported their findings in Blood.

Eligibility

Patients had to be 15 years or older, have documented evidence of HIV infection, and have a Karnofsky performance status of greater than 70%.

They had to have persistent or recurrent diffuse large B-cell lymphoma, immunoblastic lymphoma, plasmablastic lymphoma, Burkitt lymphoma, Burkitt-like NHL, or classic HL.

Patients could have had no more than 3 prior treatment regimens or 2 or fewer salvage regimens.

They had to have adequate organ function, fewer than 10% blasts in their marrow, no prior autologous or allogeneic transplant, and adequate hematopoietic progenitor cell mobilization of more than 1.5 x 10⁶ CD34+ cells/kg to be eligible.

Transplant regimen

Patients received the BEAM (carmustine, etoposide, cytarabine, and melphalan) transplant regimen on day 0. They did not receive antiretroviral therapy from the time of the start of BEAM until 7 days after completion of the preparative regimen.

Efavirenz was held for 2 weeks prior to BEAM initiation, and an alternative agent was substituted during this time period. Zidovudine was prohibited following transplant because of its myelosuppressive effects.

Patients received growth factor, transfusion, and antimicrobial supportive care according to institutional standards of the transplant center.

Patient characteristics

Of the original 43 patients enrolled, 3 patients experienced disease progression prior to the conditioning regimen and did not undergo transplant. Therefore, investigators did not include them in the study analysis.

Forty patients received ASCT at 16 different transplant centers. They were a median age of 46.9 (range, 22.5–62.2), and 35 were male.

All patients received peripheral blood stem cell grafts at a median dose of 3.9 x 10⁶ CD34+ cells/kg (range, 1.6–11.0). And all patients were able to mobilize hematopoietic progenitor cells in a median of 2 apheresis collections (range, 1–5).

Most patients (n=32; 80%) had a pre-transplant HIV viral load that was undetectable. The median viral load for those 8 patients with detectable disease was 80 copies/mL (range, 50–17,455).

Patients had a median pre-transplant CD4+ T-cell count of 249.0 CD4+/μL (range, 39–797).

Investigators followed the patients for a median of 24.8 months (range, 2.8–27.2).

Response

Seven patients died during the follow-up period, 5 within 1 year of transplant. Four of the deaths within 1 year of transplant were due to relapse or disease progression.

One-year transplant-related mortality (TRM) was 5.2%.

The 1-year overall survival (OS) probability was 87.3%, and, at 2 years, it was 82%. The 2-year progression-free survival (PFS) was 79.8%, and the cumulative incidence of relapse/progression at 2 years was 12.5%.

The probabilities for OS and PFS at 2 years were comparable for both NHL and HL patients.

The median time to post-transplant neutrophil recovery was 11 days, and 97.5% of patients recovered their neutrophil counts by day 28.

The median time to platelet recovery was 18 days, and 92.5% of patients recovered their platelet counts by day 100.

At 100 days post-transplant, 28.9% of the evaluable patients (11/38) had recovered hematologic function. And at 1 year, 74.2% (23/31) had recovered hematologic function.

Adverse events

A little more than half (55%) the patients had at least 1 infectious event within a year of transplant, including 11 who had a severe infection.

Of the 57 infections that occurred post-transplant, 25 were due to bacteria, 22 to viruses, 6 to fungal organisms, 2 to protozoa, and 2 to other organisms. No patient developed Pneumocystis jiroveci pneumonia after transplant.

Nine patients experienced a total of 13 grade 3–5 adverse events. This included infection/sepsis (5 events), venous thromboembolism (2 events), and 1 event each for esophageal candidiasis, enteritis, hyperglycemia, hypernatremia, acute appendicitis, and acute coronary syndrome.

Sixteen patients had to be re-admitted to the hospital after the transplant, for a total of 34 readmissions. Infection (18) and fever (6) were the most common reasons for readmission.

Data comparison

The investigators compared the OS and PFS results to a control group identified through the Center for International Bone Marrow Transplant Research (CIBMTR).

One hundred fifty-one controls matched for age, performance status, primary disease, and disease status at transplant were identified for the 40 HIV-lymphoma cases.

The 1-year OS for the control group was 87.7%, and the 2-year PFS was 69.5%. This compared with the 87.3% and 79.8% for OS and PFS, respectively, for the HIV-lymphoma patients.

These results, the investigators wrote, were not significantly different from outcomes of CIBMTR controls, with a hazard ratio for overall mortality in the HIV-lymphoma patients of 0.67 (95% CI: 0.30–1.50, P=0.33) compared to controls.

And the hazard ratio for treatment failure in the HIV-lymphoma patients was 0.52 (95% CI: 0.2927–1.03, P=0.06) compared to controls.

The investigators concluded that HIV infection alone should not be considered a contraindication to ASCT for patients who otherwise meet transplant inclusion criteria. And ASCT should be considered the standard of care for patients with HIV-related lymphoma, provided that the HIV infection is treatment-responsive.

The team added that these patients should also be considered “appropriate potential participants” for future ASCT clinical trials.

COPENHAGEN – Nivolumab may be an effective salvage therapy option for adults with Hodgkin lymphoma whose disease has progressed despite transplant and treatment with brentuximab vedotin, investigators reported.

In a subcohort of patients from the Checkmate 205 phase II trial, 80 patients with Hodgkin lymphoma who had disease progression following autologous stem cell transplant (ASCT) and brentuximab vedotin (Adcetris), nivolumab (Opdivo) therapy was associated with a 53% objective response rate according to independent reviewers, reported Dr. Anas Younes, chief of the lymphoma service at Memorial Sloan Kettering Cancer Center, New York.

“The PD-1 checkpoint inhibitor nivolumab is an important new treatment to address unmet needs in patients with classical Hodgkin lymphoma with progressive disease and limited treatment options, especially after autologous transplant,” he said at a briefing at the annual congress of the European Hematology Association.

Objective response rates as determined by both investigators and independent reviewers were “impressive,” and had “encouraging durability,” he added. The median duration of response at time of data cutoff was 7.8 months, and the majority of patients had ongoing responses at the time of the analysis, Dr. Younes said.

Nivolumab was recently approved by the Food and Drug Administration for the treatment of classical Hodgkin lymphoma that has relapsed or progressed after ASCT followed by brentuximab vedotin.

In the Checkmate 205 registrational trial, 80 patients (median age 37, range 18-72 years) were assigned to receive nivolumab 3 mg/kg intravenously every 2 weeks. Patients were evaluated for response by both an independent radiologic review committee (IRRC) and investigators, using 2007 International Working Group response criteria. After a median follow-up of 8.9 months, the IRRC-rated objective response rate, the primary endpoint, was 66%, including 8.8% complete remissions (CR), and 57.5% partial remissions (PR).

Dr. Younes showed a waterfall plot indicating that nearly all patients had some degree of tumor regression, and all but one patient among the responders had tumor reductions of 50% or greater from baseline.

Among 43 patients who had had no response to brentuximab vedotin, subsequent treatment with nivolumab was associated with an IRRC-rated objective response rate of 72%. As noted, the median duration of response was 7.8 months, and the median time to response was 2.1 months.

As of the last follow-up, 33 of the 53 patients with IRRC-rated responses had retained response. The IRRC-determined 6-month progression-free survival rate was 77%, and the overall survival rate was 99%.

In all, 72 patients (90%) had a treatment-related adverse event. The most common events occurring in 15% or more of patients were fatigue, infusion-related reactions, and rash. Most of the immune-mediated adverse events were of low grade and manageable, and there were no treatment-related deaths, Dr. Younes said.

Briefing moderator Dr. Anton Hagenbeek, professor of hematology at the University of Amsterdam, who was not involved in the study, asked whether nivolumab can be considered as a bridge to other therapies in this population.

Dr. Younes said that the “natural progression of a single-agent therapy that has efficacy is to combine it with other active agents, or use maybe in the adjuvant or maintenance setting in certain circumstances.”

“I don’t expect single-agent nivolumab to cure our patients,” he added.

A similarly designed clinical trial, MK-3457-087/KEYNOTE-087, is exploring the use of pembrolizumab (Keytruda). This trial is ongoing but does not have published data as yet.

Checkmate 205 is sponsored by Bristol-Myers Squibb. Dr. Younes has served as a consultant/advisor, received honoraria and/or research funding from Gilead Sciences, Curis, Incyte, Janssen, Seattle Genetics, Novartis, Celgene, Millennium, and Sanofi. Dr. Hagenbeek reported no relevant disclosures.

A similarly designed clinical trial, MK-3457-087/KEYNOTE-087, is exploring the use of pembrolizumab (Keytruda). This trial is ongoing but does not have published data as yet.

Checkmate 205 is sponsored by Bristol-Myers Squibb. Dr. Younes has served as a consultant/advisor, received honoraria and/or research funding from Gilead Sciences, Curis, Incyte, Janssen, Seattle Genetics, Novartis, Celgene, Millennium, and Sanofi. Dr. Hagenbeek reported no relevant disclosures.

COPENHAGEN – Nivolumab may be an effective salvage therapy option for adults with Hodgkin lymphoma whose disease has progressed despite transplant and treatment with brentuximab vedotin, investigators reported.

In a subcohort of patients from the Checkmate 205 phase II trial, 80 patients with Hodgkin lymphoma who had disease progression following autologous stem cell transplant (ASCT) and brentuximab vedotin (Adcetris), nivolumab (Opdivo) therapy was associated with a 53% objective response rate according to independent reviewers, reported Dr. Anas Younes, chief of the lymphoma service at Memorial Sloan Kettering Cancer Center, New York.

“The PD-1 checkpoint inhibitor nivolumab is an important new treatment to address unmet needs in patients with classical Hodgkin lymphoma with progressive disease and limited treatment options, especially after autologous transplant,” he said at a briefing at the annual congress of the European Hematology Association.

Objective response rates as determined by both investigators and independent reviewers were “impressive,” and had “encouraging durability,” he added. The median duration of response at time of data cutoff was 7.8 months, and the majority of patients had ongoing responses at the time of the analysis, Dr. Younes said.

Nivolumab was recently approved by the Food and Drug Administration for the treatment of classical Hodgkin lymphoma that has relapsed or progressed after ASCT followed by brentuximab vedotin.

In the Checkmate 205 registrational trial, 80 patients (median age 37, range 18-72 years) were assigned to receive nivolumab 3 mg/kg intravenously every 2 weeks. Patients were evaluated for response by both an independent radiologic review committee (IRRC) and investigators, using 2007 International Working Group response criteria. After a median follow-up of 8.9 months, the IRRC-rated objective response rate, the primary endpoint, was 66%, including 8.8% complete remissions (CR), and 57.5% partial remissions (PR).

Dr. Younes showed a waterfall plot indicating that nearly all patients had some degree of tumor regression, and all but one patient among the responders had tumor reductions of 50% or greater from baseline.

Among 43 patients who had had no response to brentuximab vedotin, subsequent treatment with nivolumab was associated with an IRRC-rated objective response rate of 72%. As noted, the median duration of response was 7.8 months, and the median time to response was 2.1 months.

As of the last follow-up, 33 of the 53 patients with IRRC-rated responses had retained response. The IRRC-determined 6-month progression-free survival rate was 77%, and the overall survival rate was 99%.

In all, 72 patients (90%) had a treatment-related adverse event. The most common events occurring in 15% or more of patients were fatigue, infusion-related reactions, and rash. Most of the immune-mediated adverse events were of low grade and manageable, and there were no treatment-related deaths, Dr. Younes said.

Briefing moderator Dr. Anton Hagenbeek, professor of hematology at the University of Amsterdam, who was not involved in the study, asked whether nivolumab can be considered as a bridge to other therapies in this population.

Dr. Younes said that the “natural progression of a single-agent therapy that has efficacy is to combine it with other active agents, or use maybe in the adjuvant or maintenance setting in certain circumstances.”

“I don’t expect single-agent nivolumab to cure our patients,” he added.

A single-center retrospective study of 39 pregnant women diagnosed with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL) during pregnancy indicates that delaying treatment until the second trimester is “likely safe and results in acceptable” outcomes for both mother and child.

Investigators also found that deferring therapy until after delivery did not adversely affect maternal outcomes.

In order to clarify the sometimes conflicting reports regarding management of lymphoma during pregnancy, investigators at MD Anderson Cancer Center in Houston, Texas, undertook the study to determine whether administering standard chemotherapy during the second and third trimesters has acceptable maternal and fetal outcomes.

Michelle A. Fanale, MD, and colleagues published their findings in JAMA Oncology.

Patient characteristics

Investigators identified 31 women with HL and 8 with NHL who were diagnosed between 1991 and 2014 and had sufficient pregnancy and follow-up data.
 
The women were a median age of 28 years (range 19-38). The patients with NHL were significantly older, P=0.004.

Approximately 20% of patients had B symptoms. Most were stage II disease (72%), and 80% were ECOG performance status 0 or 1.

About two thirds of patients had hemoglobin levels less than 12 g/dL.

Most patients did not have extranodal nonbone-marrow disease (82%), although there was a significant difference between those with HL (90%) and NHL (50%), P=0.03.

One third of patients had bulky disease, and 88% were in their second or third trimesters at diagnosis.

Three women electively terminated their pregnancies at diagnosis. Of the 36 remaining patients, 24 (61%) began antenatal therapy and 12 (31%) postponed therapy until after delivery.

Four patients received radiation therapy above the diaphragm at a median dose of 40.4 Gy.

Obstetric outcomes

Antenatal therapy was not associated with increased incidence of preterm delivery. Of the 24 women who received treatment during pregnancy, 7 (29%) gave birth prematurely compared with 5 of the 12 women (42%) who postponed treatment until after delivery, P=0.73.

The investigators noted that the miscarriage rate was approximately 10%, which was higher than previous studies.

Four patients had miscarriages, 2 during the first trimester and 2 during the second. Both patients who had miscarriages in the first trimester had received lymphoma treatment during that time.

And one of the patients who had antenatal therapy during the second trimester and had a miscarriage was critically ill, which the investigators believed was a contributing factor.

The second woman who miscarried after therapy in the second trimester had conceived twins through in vitro fertilization and miscarried at 23 weeks after ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) therapy had been initiated at gestational week 15.

Investigators had fetal outcomes available for 31 of 32 patients who did not terminate or have a miscarriage. And these 31 infants had no anomalies at birth.

The investigators said that although the follow-up time is relatively short, they observed no malformations in the newborns.

Treatment responses and survival

The overall response rate (OR) was 91.7% and the complete response (CR) rate was 75.0% for the 24 patients who started treatment during pregnancy.

And for those 12 women who deferred therapy until delivery, both ORR and CR rates were 91.7%.

The 5-year progression-free survival (PFS) and OS were 74.7% and 82.4%, respectively, for all women. The median follow-up was 67.9 months (range 8.8 to 277.5).

For the 31 women with HL, the 5-year PFS and OS were 69.9% and 80%, respectively.

And for the 8 women with NHL, the 5-year PFS and OS were 85.7% and 83.3%, respectively.

Investigators found no difference in PFS or OS (P=0.84) based on undergoing antenatal lymphoma treatment among the 36 women who did not terminate their pregnancies at diagnosis.

The investigators conducted a univariate analysis and found that for the 36 women who did not electively terminate their pregnancies, the following were associated with increased risk of disease progression:

•    Bulky disease—hazard ratio [HR] 3.6, P = 0.06
•    Extranodal nonbone marrow involvement—HR 4.2, P = 0.04
•    Poor ECOG performance status—HR 3.9, P = 0.005

Poor performance status was also associated with OS, HR 8.88, P = 0.004.

Multivariate analysis revealed significant associations in terms of OS and PFS for extranodal nonbone marrow involvement and performance status:

•    Nonbone marrow involvement—OS HR, 73.5, P = 0.02; PFS HR 8.26, P = 0.01
•    Performance status—OS HR, 26.7, P = 0.003; PFS HR, 4.89, P = 0.002

The investigators concluded that because they found no differences in PFS or OS according to whether patients received antenatal therapy, they believe that disease factors, rather than treatment-related factors, influence worse maternal outcomes.

They recommended delaying therapy until the second trimester if that can be accomplished without harm to the patient.

CHICAGO – Brentuximab vedotin appears to be safe and effective in eradicating residual disease after induction chemotherapy and may replace radiation for consolidation in patients with limited stage non-bulky Hodgkin lymphoma, Dr. Steven I. Park reported at the annual meeting of the American Society of Clinical Oncology.

After two cycles of ABVD [doxorubicin (Adriamycin), bleomycin, vinblastine, and dacarbazine], 72% of 40 evaluable patients achieved PET-negative disease. After completing brentuximab vedotin therapy, 90% of patients had PET-negative disease. With a median follow-up of 12 months, the estimated 1-year progression-free survival rate is 91%, and the overall survival rate is 96%.

The current standard therapy for limited stage Hodgkin lymphoma is about 4-6 cycles of chemotherapy with or without consolidative radiation therapy. The goal of the study was to reduce the number of cycles of chemotherapy and avoid radiation therapy, which has an unclear overall survival advantage and risks long-term side effects, noted Dr. Park of the University of North Carolina at Chapel Hill, Lineberger Comprehensive Cancer Center.

In this phase II multicenter study, 41 patients with previously untreated limited stage non-bulky Hodgkin lymphoma received ABVD followed by brentuximab vedotin (NCT01578967). Study patients’ median age was 29 years (range 19-67), and 46% presented with unfavorable disease. Over 90% of patients received four or fewer cycles of ABVD, and one patient received radiation due to disease progression.

Grade 3 or higher toxicities associated with brentuximab vedotin included neutropenia in three patients and peripheral neuropathy and rash in one patient each. One patient developed pancreatitis and died due to sepsis and hepatic failure, a rare complication of brentuximab vedotin that cautions regarding its use in patients with hepatic function limitations, Dr. Park said.

According to Seattle Genetics, the maker of brentuximab vedotin, the drug is an anti-CD30 monoclonal antibody attached by a protease-cleavable linker to the cytotoxic agent monomethyl auristatin E, which leads to target cell death when internalized into CD30-expressing tumor cells.

Adolescents and young adults (AYAs) are less likely than children to survive 8 relatively common types of cancer, according to a long-running study of cancer survival across Europe.

The study showed that AYAs had significantly worse survival rates than children if they were diagnosed with acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin or non-Hodgkin lymphoma (NHL), and 4 types of solid tumor malignancies.

The study’s authors say that variations in survival between age groups are due to a number of factors, including delays in diagnosis and treatment, a lack of treatment guidelines and clinical trials specifically for AYAs, and differences in the biology of some cancers.

“The good news is that the number of children, adolescents, and young adults surviving for at least 5 years after diagnosis has risen steadily over time in Europe,” said author Annalisa Trama, PhD, of The National Institute of Cancer (Istituto Nazionale dei Tumori: Fondazione IRCCS) in Milan, Italy.

“Across all cancers, the level of improvement is similar in these age groups. This contrasts with earlier results that adolescents and young adults diagnosed up to the 1990s were lagging behind children in terms of survival.”

“However, we found that adolescents and young adults still tend to die earlier than children for several cancers common to these age groups, particularly blood cancers like leukemias and non-Hodgkin’s lymphoma.”

Dr Trama and her colleagues reported these findings in The Lancet Oncology.

The researchers compared survival between AYAs (ages 15 to 39), children (ages 0 to 14), and adults (ages 40 to 69) who were diagnosed from 2000 to 2007 and followed up to at least 2008.

The team analyzed data from population-based cancer registries covering all or part of 27 European countries* and estimated 5-year survival for 56,505 cancer cases in children; 312,483 in AYAs; and 3,567,383 in adults. The researchers also analyzed changes in survival over time from 1999 to 2007.

For AYAs, survival at 5 years from diagnosis for all cancers combined was 82% for 2005-2007, which is up from 79% for 1999-2001 (P<0.0001). In children, survival improved from 76% to 79% over the same time period (P<0.0001).

Survival improved significantly in children and AYAs for ALL (P<0.0001) and NHL (P<0.0001 in AYAs and P=0.023 in children). On the other hand, between 1999 and 2007, survival rates remained unchanged for AYAs with AML (around 50%).

Overall, AYAs had slightly better 5-year survival than children because they were diagnosed more often with cancers with fairly good prognoses—Hodgkin lymphoma, NHL, germ cell tumors, melanoma, thyroid cancer, and breast cancer.

However, the overall survival rates conceal differences between specific cancers. Survival was significantly worse for AYAs than for children when it came to 8 relatively common cancers affecting both age groups:

• ALL—55.6% for AYAs and 85.8% for children (P<0.0001)
• AML—49.8% and 60.5%, respectively (P<0.0001)
• Hodgkin lymphoma—92.9% and 95.1%, respectively (P<0.0001)
• NHL—77.4% and 83.0%, respectively (P<0.0001)
• Astrocytomas—46.4% and 61.9%, respectively (P<0.0001)
• Ewing’s sarcoma of bone—49.3% and 66.6%, respectively (P<0.0001)
• Rhabdomyosarcoma—37.8% and 66.6%, respectively (P<0.0001)
• Osteosarcoma—61.5% and 66.8%, respectively (P=0.011).

AYAs had a survival advantage over adults for almost all major cancers affecting both age groups, supporting the idea that younger patients with few other illnesses are likely to fare better than older patients.

There are only 2 types of cancer for which AYAs were at a survival disadvantage—breast (83.5% vs 87.0%) and prostate (79.9% vs 89.8%).

Dr Trama and her colleagues pointed out that this analysis pre-dates recent initiatives to improve outcomes for AYAs that have been implemented in several European countries.

“The European Network for Teenagers and Young Adults with Cancer is advocating collaboration between pediatric and adult oncologists, greater access to clinical trials and research to improve treatments for this specific age group, as well as developing adolescent and young adult-specific practice guidelines, encouraging healthier lifestyles and the greater involvement of patients and patients support groups,” Dr Trama said.

“This study will provide an important starting point from which to evaluate whether these initiatives will reduce the gulf in survival between European adolescents and young adults and children with cancer.”

“Across all cancers, the level of improvement is similar in these age groups. This contrasts with earlier results that adolescents and young adults diagnosed up to the 1990s were lagging behind children in terms of survival.”

“However, we found that adolescents and young adults still tend to die earlier than children for several cancers common to these age groups, particularly blood cancers like leukemias and non-Hodgkin’s lymphoma.”

Dr Trama and her colleagues reported these findings in The Lancet Oncology.

The researchers compared survival between AYAs (ages 15 to 39), children (ages 0 to 14), and adults (ages 40 to 69) who were diagnosed from 2000 to 2007 and followed up to at least 2008.

The team analyzed data from population-based cancer registries covering all or part of 27 European countries* and estimated 5-year survival for 56,505 cancer cases in children; 312,483 in AYAs; and 3,567,383 in adults. The researchers also analyzed changes in survival over time from 1999 to 2007.

For AYAs, survival at 5 years from diagnosis for all cancers combined was 82% for 2005-2007, which is up from 79% for 1999-2001 (P<0.0001). In children, survival improved from 76% to 79% over the same time period (P<0.0001).

Survival improved significantly in children and AYAs for ALL (P<0.0001) and NHL (P<0.0001 in AYAs and P=0.023 in children). On the other hand, between 1999 and 2007, survival rates remained unchanged for AYAs with AML (around 50%).

Overall, AYAs had slightly better 5-year survival than children because they were diagnosed more often with cancers with fairly good prognoses—Hodgkin lymphoma, NHL, germ cell tumors, melanoma, thyroid cancer, and breast cancer.

However, the overall survival rates conceal differences between specific cancers. Survival was significantly worse for AYAs than for children when it came to 8 relatively common cancers affecting both age groups:

• ALL—55.6% for AYAs and 85.8% for children (P<0.0001)
• AML—49.8% and 60.5%, respectively (P<0.0001)
• Hodgkin lymphoma—92.9% and 95.1%, respectively (P<0.0001)
• NHL—77.4% and 83.0%, respectively (P<0.0001)
• Astrocytomas—46.4% and 61.9%, respectively (P<0.0001)
• Ewing’s sarcoma of bone—49.3% and 66.6%, respectively (P<0.0001)
• Rhabdomyosarcoma—37.8% and 66.6%, respectively (P<0.0001)
• Osteosarcoma—61.5% and 66.8%, respectively (P=0.011).

AYAs had a survival advantage over adults for almost all major cancers affecting both age groups, supporting the idea that younger patients with few other illnesses are likely to fare better than older patients.

There are only 2 types of cancer for which AYAs were at a survival disadvantage—breast (83.5% vs 87.0%) and prostate (79.9% vs 89.8%).

Dr Trama and her colleagues pointed out that this analysis pre-dates recent initiatives to improve outcomes for AYAs that have been implemented in several European countries.

“The European Network for Teenagers and Young Adults with Cancer is advocating collaboration between pediatric and adult oncologists, greater access to clinical trials and research to improve treatments for this specific age group, as well as developing adolescent and young adult-specific practice guidelines, encouraging healthier lifestyles and the greater involvement of patients and patients support groups,” Dr Trama said.

“This study will provide an important starting point from which to evaluate whether these initiatives will reduce the gulf in survival between European adolescents and young adults and children with cancer.”

Adolescents and young adults (AYAs) are less likely than children to survive 8 relatively common types of cancer, according to a long-running study of cancer survival across Europe.

The study showed that AYAs had significantly worse survival rates than children if they were diagnosed with acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), Hodgkin or non-Hodgkin lymphoma (NHL), and 4 types of solid tumor malignancies.

The study’s authors say that variations in survival between age groups are due to a number of factors, including delays in diagnosis and treatment, a lack of treatment guidelines and clinical trials specifically for AYAs, and differences in the biology of some cancers.

“The good news is that the number of children, adolescents, and young adults surviving for at least 5 years after diagnosis has risen steadily over time in Europe,” said author Annalisa Trama, PhD, of The National Institute of Cancer (Istituto Nazionale dei Tumori: Fondazione IRCCS) in Milan, Italy.

Brentuximab vedotin

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has recommended extending the current conditional approval of brentuximab vedotin (Adcetris) to include the treatment of adults with CD30+ Hodgkin lymphoma (HL) at increased risk of relapse or progression following autologous stem cell transplant (ASCT).

The CHMP’s recommendation will now be reviewed by the European Commission (EC).

If the recommendation is formally adopted by the EC, brentuximab vedotin will be approved for the aforementioned indication in the 28 member states of the European Union as well as Norway, Liechtenstein, and Iceland.

Brentuximab vedotin already has conditional marketing authorization from the EC for 2 indications:

• To treat adults with relapsed or refractory CD30+ HL after ASCT or following at least 2 prior therapies when ASCT or multi-agent chemotherapy is not a treatment option
• To treat adults with relapsed or refractory systemic anaplastic large-cell lymphoma (sALCL).

In January 2016, the EC approved a Type II variation to include data on the retreatment of adult patients with HL or sALCL who previously responded to brentuximab vedotin and later relapsed.

Brentuximab vedotin is under joint development by Seattle Genetics and Takeda Pharmaceutical Company Limited.

AETHERA trial

The CHMP’s recommendation to extend the approval of brentuximab vedotin is based on results from the phase 3 AETHERA trial.

The trial was designed to compare brentuximab vedotin to placebo, both administered for up to 16 cycles (approximately 1 year) every 3 weeks following ASCT. Results from the trial were published in The Lancet in March 2015 and presented at the 2014 ASH Annual Meeting.

The study enrolled 329 HL patients at risk of relapse or progression, including 165 on the brentuximab vedotin arm and 164 on the placebo arm.

Patients were eligible for enrollment if they had a history of primary refractory HL, relapsed within a year of receiving frontline chemotherapy, and/or had disease outside of the lymph nodes at the time of pre-ASCT relapse.

Brentuximab vedotin conferred a significant increase in progression-free survival over placebo, with a hazard ratio of 0.57 (P=0.001). The median progression-free survival was 43 months for patients who received brentuximab vedotin and 24 months for those who received placebo.

The most common adverse events (≥20%), of any grade and regardless of causality, in the brentuximab vedotin arm were neutropenia (78%), peripheral sensory neuropathy (56%), thrombocytopenia (41%), anemia (27%), upper respiratory tract infection (26%), fatigue (24%), peripheral motor neuropathy (23%), nausea (22%), cough (21%), and diarrhea (20%).

The most common adverse events (≥20%), of any grade and regardless of causality, in the placebo arm were neutropenia (34%), upper respiratory tract infection (23%), and thrombocytopenia (20%).

In all, 67% of patients on the brentuximab vedotin arm experienced peripheral neuropathy. Of those patients, 85% had resolution (59%) or partial improvement (26%) in symptoms at the time of their last evaluation, with a median time to improvement of 23 weeks (range, 0.1-138).

A new study suggests that cancer patients with HIV are less likely to receive cancer treatment, regardless of insurance status and comorbidities.

Patients with HIV were less likely than their HIV-free peers to receive treatment for Hodgkin lymphoma, diffuse large B-cell lymphoma, and 7 solid tumor malignancies.

Gita Suneja, MD, of the University of Utah in Salt Lake City, and her colleagues reported these findings in Cancer.

The team used the National Cancer Data Base to study non-elderly US adults diagnosed with 10 common cancers from 2003 to 2011. There were a total of 10,265 HIV-infected patients and 2,219,232 HIV-free patients.

The researchers examined associations between HIV status and lack of cancer treatment, taking into account insurance status and comorbidities.

The results showed a lack of treatment among HIV patients for all of the cancers studied except anal cancer (relative risk [RR]=1.20, P=0.333).

So HIV-infected patients were more likely to lack cancer treatment for:

• Hodgkin lymphoma (RR=1.92, P<0.001)
• Diffuse large B-cell lymphoma (RR=1.82, P<0.001)
• Head and neck cancer (RR=1.48, P=0.013)
• Upper gastrointestinal tract cancer (RR=2.62, P<0.001)
• Colorectal cancer (RR=1.70, P=0.006)
• Lung cancer (RR=2.46, P<0.001)
• Breast cancer (RR=2.14, P=0.015)
• Cervical cancer (RR=2.81, P<0.001)
• Prostate cancer (RR=2.16, P<0.001).

The researchers said factors that predicted a lack of cancer treatment among HIV-infected individuals varied between those with solid tumors and those with lymphomas.

Advanced stage at the time of cancer diagnosis (stage IV vs stage I) meant HIV patients with solid tumors were less likely to receive cancer treatment, but lymphoma patients were more likely to receive cancer treatment.

Having a higher modified Charlson-Deyo comorbidity score (1 or 2+ vs 0) predicted a lack of cancer treatment for HIV-infected patients with lymphoma but not those with solid tumors.

And older age (45-64 vs 18-44) was associated with a lack of treatment for HIV-infected patients regardless of cancer type, but this was only significant for lymphoma patients.

For the entire cohort, black race (vs white) and a lack of private insurance (Medicaid, Medicare, uninsured, or unknown insurance status) were significant predictors for a lack of cancer treatment among HIV patients.

Still, the researchers noted that, even among privately insured patients, HIV-infected individuals were less likely to receive cancer treatment.

Dr Suneja and her colleagues said several factors may contribute to these findings. For one, HIV-infected patients have historically been excluded from cancer clinical trials, thereby limiting the applicability of trial results for this population.

In addition, cancer treatment guidelines specific to HIV-infected patients are not available for most cancer types. And clinicians may lack experience treating HIV-infected patients with cancer.

Furthermore, the psychosocial and economic challenges associated with the dual management of cancer and HIV treatment may make adherence to treatment a challenge.
