SAN DIEGO—A newly approved treatment regimen provides a survival benefit over standard therapy for patients with CD30-positive peripheral T-cell lymphomas (PTCLs), according to a presentation at the 2018 ASH Annual Meeting.

In the ECHELON-2 trial, patients who received brentuximab vedotin (BV) plus cyclophosphamide, doxorubicin, and prednisone (CHP) had superior progression-free survival (PFS) and overall survival (OS) compared to patients who received standard treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP).

These results supported the recent U.S. approval of BV in combination with CHP for adults with previously untreated, systemic anaplastic large-cell lymphoma or other CD30-expressing PTCLs, including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified.

“ECHELON-2 is the first prospective trial in peripheral T-cell lymphoma to show an overall survival benefit over CHOP,” said Steven M. Horwitz, MD, of Memorial Sloan Kettering Cancer Center in Basking Ridge, New Jersey.

Dr. Horwitz presented results from this trial at ASH as abstract 997. Results were simultaneously published in The Lancet.

Patients and treatment

ECHELON-2 (NCT01777152) enrolled 452 patients with previously untreated, CD30-positive PTCL. Subtypes included ALK-positive (n=98) or -negative (n=218) systemic anaplastic large-cell lymphoma, PTCL not otherwise specified (n=72), angioimmunoblastic T-cell lymphoma (n=54), enteropathy-associated T-cell lymphoma (n=7), and adult T-cell leukemia/lymphoma (n=3).

Patients were randomized to receive BV-CHP plus placebo (n=226) or CHOP plus placebo (n=226) every 3 weeks for six to eight cycles.

At baseline, the median age was 58 in both the BV-CHP arm (range, 18-85) and the CHOP arm (range, 18-83). The majority of patients were male—59% in the BV-CHP arm and 67% in the CHOP arm—and most patients had stage III/IV disease—81% and 80%, respectively.

Eighty-nine percent of patients in the BV-CHP arm and 81% in the CHOP arm completed six or more cycles of their assigned treatment.

Twenty-seven percent of patients in the BV-CHP arm and 19% in the CHOP arm received consolidation consisting of radiotherapy (6% and 3%, respectively) and/or stem cell transplant (22% and 17%).

Twenty-six percent of patients in the BV-CHP arm and 42% in the CHOP arm received systemic therapy for residual or progressive disease, and 4% of patients in each arm received palliative radiation.

Efficacy

The overall response rate was 83% in the BV-CHP arm and 72% in the CHOP arm (P=0.0032). The complete response rates were 68% and 56%, respectively (P=0.0066).

At a median follow-up of 36.2 months, the median PFS was 48.2 months in the BV-CHP arm and 20.8 months in the CHOP arm. The rate of death or progression was 42% in the BV-CHP arm and 55% in the CHOP arm (hazard ratio=0.71, P=0.011).

At a median follow-up of 42.1 months, the median OS was not reached in either treatment arm. The rate of death was 23% in the BV-CHP arm and 32% in the CHOP arm (hazard ratio=0.66, P=0.0244).

Dr. Horwitz noted that this study was not powered to determine differences in OS or PFS according to PTCL subtypes.

Safety

BV-CHP had a comparable safety profile to CHOP, Dr. Horwitz said.

The rate of adverse events (AEs) was 99% in the BV-CHP arm and 98% in the CHOP arm. Grade 3 or higher AEs occurred in 66% and 65% of patients, respectively. Serious AEs occurred in 39% and 38%, respectively.

Three percent of patients in the BV-CHP arm and 4% of those in the CHOP arm had fatal AEs.

The most common AEs of any grade occurring in at least 20% of patients (in the BV-CHP and CHOP arms, respectively) were:

• Nausea (46% and 38%)
• Peripheral sensory neuropathy (45% and 41%)
• Neutropenia (38% for both)
• Diarrhea (38% and 20%)
• Constipation (29% and 30%)
• Alopecia (26% and 25%)
• Pyrexia (26% and 19%)
• Vomiting (26% and 17%)
• Fatigue (24% and 20%)
• Anemia (21% and 16%).

This research was funded by Seattle Genetics Inc. and Millennium Pharmaceuticals Inc., a wholly owned subsidiary of Takeda Pharmaceutical Company Limited.

SAN DIEGO—An updated analysis of the JULIET trial showed that tisagenlecleucel produced a high rate of durable responses in adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL).

After a median follow-up of 19 months, two-thirds of adults with relapsed/refractory DLBCL who had early responses to the chimeric antigen receptor (CAR) T-cell therapy remained in remission with no evidence of minimal residual disease.

“Since the previous report, no new deaths have been reported due to any cause other than patient disease progression, no treatment-related mortality was seen throughout the study, and there were three early deaths, all related to lymphoma that progressed,” said study investigator Richard Thomas Maziarz, MD, of Oregon Health & Science University’s Knight Cancer Institute in Portland.

Dr. Maziarz and his colleagues reported the updated study results at the 2018 ASH Annual Meeting (abstract 1684). Results were published simultaneously in The New England Journal of Medicine. Data reported here are based on the ASH data.

JULIET then

In the phase 2, single-arm trial, investigators enrolled adults with DLBCL who had relapsed or were refractory after two or more prior lines of therapy and who were either ineligible for hematopoietic stem cell transplant (HSCT) or who experienced disease progression after HSCT.

Interim results of the study were previously reported at the 22nd Congress of the European Hematology Association in 2017.

At that meeting, Gilles Salles, MD, PhD, of the University of Lyon in France, presented results of an analysis of available efficacy data on 51 patients with at least 3 months of follow-up.

In this population, the best overall response rate (ORR) was 59%. Three-month ORR was 45%, consisting of 37% complete responses (CR) and 8% partial responses (PR).

Relapse-free survival at 6 months was 79%, and all patients who had responses at 3 months continued to have responses at the time of data cutoff.

JULIET now

The current analysis was completed after a median time from infusion to data cutoff of 19 months as of May 21, 2018. The analysis included 115 patients who received CAR T-cell infusions, 99 of whom were evaluable for efficacy.

As reported at ASH, the best ORR, the primary endpoint, was 54%, comprised of 40% CR and 13% PR.

Fifty-four percent of patients who had achieved PR converted to CR.

The response rates were consistent across all subgroups, regardless of age, sex, previous response status, International Prognostic Index score at enrollment, prior therapy, molecular subtype, and other factors.

Estimated relapse-free survival 12 months after documentation of an initial response was 64%.

The median duration of response had not been reached at the time of data cutoff, and the median overall survival had not been reached for patients with a CR.

Median overall survival in this heavily pretreated population as a whole (all patients who received CAR T-cell infusions) was 11.1 months and not reached for patients in CR.

Adverse events of special interest included grade 3 or 4 cytokine release syndrome (CRS) in 23% of patients, prolonged cytopenia in 34%, infections in 19%, neurologic events in 11%, febrile neutropenia in 15%, and tumor lysis syndrome in 2%.

There were no deaths attributable to the treatment, CRS, or to cerebral edema, a complication of CAR T-cell therapy that appears to be related to the costimulatory molecule used in various constructs.

SAN DIEGO – Ixazomib improved progression-free survival following autologous stem cell transplantation (ASCT) in patients with newly diagnosed multiple myeloma, according to results of a double-blind, randomized, placebo-controlled, phase 3 trial.

Andrew Bowser/MDedge News

Treatment with the oral proteasome inhibitor for 24 months was well tolerated, had a low discontinuation rate, and improved progression-free survival by 39% versus placebo, according to Meletios A. Dimopoulos, MD, of the National and Kapodistrian University of Athens.

These findings suggest ixazomib (Ninlaro) represents a “new treatment option for maintenance after transplantation,” Dr. Dimopoulos said at the annual meeting of the American Society of Hematology.

The trial, known as TOURMALINE-MM3, is the first-ever randomized, double-blind, placebo-controlled study of a proteasome inhibitor used as maintenance after ASCT, according to Dr. Dimopoulos. Lenalidomide is approved in that setting, but 29% of patients who start the treatment discontinue because of treatment-related adverse events.

“Proteasome inhibitors have a different mechanism of action and may provide an alternative to lenalidomide,” Dr. Dimopoulos said at an oral abstract session. Ixazomib has a manageable toxicity profile and “convenient” weekly oral dosing, making it “well suited” for maintenance.

When asked by an attendee whether ixazomib would become “the standard of care” for younger patients with myeloma in this setting, Dr. Dimopoulos replied the results show that ixazomib “is an option for patients, especially for those where a physician may believe that a proteasome inhibitor may be indicated.”

However, when pressed by an attendee to comment on how ixazomib compares with lenalidomide for maintenance, Dr. Dimopoulos remarked that current maintenance studies are moving in the direction of combining therapies.

“I think that instead of saying, ‘is ixazomib better than lenalidomide?’ or vice versa, it is better to see how one may combine those drugs in subsets of patients, or even combine these drugs with other agents,” he said.

The TOURMALINE-MM3 study included 656 patients randomized posttransplantation to receive weekly ixazomib or placebo for up to 2 years.

The median progression-free survival was 26.5 months for ixazomib versus 21.3 months for placebo (P = .002; hazard ratio, 0.720; 95% confidence interval, 0.582-0.890). Median overall survival had not been reached in either ixazomib or placebo arms as of this report, with a median follow-up of 31 months.

The discontinuation rate was 7% for ixazomib versus 5% for placebo, according to the investigator. Moreover, ixazomib was associated with “low toxicity” and no difference in the rates of new primary malignancies, at 3% in both arms.

A manuscript describing results of the TOURMALINE-MM3 study is in press in the Lancet, with an expected online publication date of Dec. 10, Dr. Dimopoulos told attendees. Other studies are ongoing to evaluate ixazomib combinations and treatment to progression in this setting.

TOURMALINE-MM3 is sponsored by Takeda (Millennium), the maker of ixazomib. Dr. Dimopoulos reported honoraria and consultancy with Janssen, Takeda Pharmaceutical, Amgen, Bristol-Myers Squibb, and Celgene.

SAN DIEGO – Ixazomib improved progression-free survival following autologous stem cell transplantation (ASCT) in patients with newly diagnosed multiple myeloma, according to results of a double-blind, randomized, placebo-controlled, phase 3 trial.

Andrew Bowser/MDedge News

Treatment with the oral proteasome inhibitor for 24 months was well tolerated, had a low discontinuation rate, and improved progression-free survival by 39% versus placebo, according to Meletios A. Dimopoulos, MD, of the National and Kapodistrian University of Athens.

These findings suggest ixazomib (Ninlaro) represents a “new treatment option for maintenance after transplantation,” Dr. Dimopoulos said at the annual meeting of the American Society of Hematology.

The trial, known as TOURMALINE-MM3, is the first-ever randomized, double-blind, placebo-controlled study of a proteasome inhibitor used as maintenance after ASCT, according to Dr. Dimopoulos. Lenalidomide is approved in that setting, but 29% of patients who start the treatment discontinue because of treatment-related adverse events.

“Proteasome inhibitors have a different mechanism of action and may provide an alternative to lenalidomide,” Dr. Dimopoulos said at an oral abstract session. Ixazomib has a manageable toxicity profile and “convenient” weekly oral dosing, making it “well suited” for maintenance.

When asked by an attendee whether ixazomib would become “the standard of care” for younger patients with myeloma in this setting, Dr. Dimopoulos replied the results show that ixazomib “is an option for patients, especially for those where a physician may believe that a proteasome inhibitor may be indicated.”

However, when pressed by an attendee to comment on how ixazomib compares with lenalidomide for maintenance, Dr. Dimopoulos remarked that current maintenance studies are moving in the direction of combining therapies.

“I think that instead of saying, ‘is ixazomib better than lenalidomide?’ or vice versa, it is better to see how one may combine those drugs in subsets of patients, or even combine these drugs with other agents,” he said.

The TOURMALINE-MM3 study included 656 patients randomized posttransplantation to receive weekly ixazomib or placebo for up to 2 years.

The median progression-free survival was 26.5 months for ixazomib versus 21.3 months for placebo (P = .002; hazard ratio, 0.720; 95% confidence interval, 0.582-0.890). Median overall survival had not been reached in either ixazomib or placebo arms as of this report, with a median follow-up of 31 months.

The discontinuation rate was 7% for ixazomib versus 5% for placebo, according to the investigator. Moreover, ixazomib was associated with “low toxicity” and no difference in the rates of new primary malignancies, at 3% in both arms.

SAN DIEGO – Two-thirds of adults with relapsed or refractory diffuse large B-cell lymphoma who had early responses to chimeric antigen receptor T-cell (CAR T) therapy with tisagenlecleucel (Kymriah) remain in remission with no evidence of minimal residual disease, according to an updated analysis of the JULIET trial.

In the single-arm, open-label trial, the overall response rate after 19 months of follow-up was 54%, including 40% complete remissions and 14% partial remissions. The median duration of response had not been reached at the time of data cutoff, and the median overall survival had not been reached for patients with a complete remission. Overall survival in this heavily pretreated population as a whole (all patients who received CAR T-cell infusions) was 11.1 months.

Adverse events were similar to those previously reported and were manageable, according to investigator Richard Thomas Maziarz, MD, from the Oregon Health & Science Knight Cancer Institute in Portland.

In this video interview at the annual meeting of the American Society of Hematology, Dr. Maziarz discusses the promising results using CAR T cells in this difficult to treat population.

SAN DIEGO – Investigators demonstrated the feasibility of delivering genomic results in 7 days in a population of older, newly diagnosed patients with acute myeloid leukemia (AML).

The Beat AML Master Trial is an ongoing umbrella study that harnesses cytogenetic information and next generation sequencing to match patients with targeted therapies across a number of substudies or outside of the trial’s multicenter network.

The researchers chose AML for this precision-medicine study because of its rapid onset and lethal nature, its heterogeneity, and the availability of more-targeted therapies, said Amy Burd, PhD, of the Leukemia & Lymphoma Society, which is sponsoring the study.

Initial data from the trial showed that more than 95% of patients were assigned to treatment in 7 days or less, based on their personalized genomic information.

Overall, 285 patients had usable genomic screening data and were assigned to treatment. Of those patients, 273 were assigned to a treatment within 7 days, Dr. Burd reported at the annual meeting of the American Society of Hematology.

The speed of delivering these results is critical, said Joseph Mikhael, MD, chief medical officer for the International Myeloma Foundation in Phoenix, who moderated a media briefing on personalized medicine.

“One of the greatest challenges we faced in the concept of personalized medicine is by the time you’ve determined what is best for that patient ... the horse is already out of the barn,” Dr. Mikhael said. “You have to have started the patient on treatment already or else their disease could have progressed quite rapidly.”

In the past, genomic results might come back a month after the patient started therapy. “It was really almost academic,” he said.

In the Beat AML study, more than half (146 patients) were treated based on their AML subtype. The remaining patients (139) were not treated: 2.5% of patients died within 7 days, 7% of patients chose an alternative treatment prior to assignment, 20% chose standard of care, 9.1% chose an alternative trial after assignment, 8.1% chose palliative care, and the remainder had a reason that was not specified.

“The treatment decisions are made for what’s best for the patient even if that means a study outside of Beat AML,” Dr. Burd said.

Currently, there are 11 substudies offering treatment to trial participants across 13 clinical sites. There has been promising efficacy in many of the treatment arms, Dr. Burd said.

In the future, the researchers are looking to expand the substudies to look into novel drug combinations for certain AML subtypes, specifically isocitrate dehydrogenase 2–mutated groups.

Dr. Burd is an employee of the Leukemia & Lymphoma Society. Other coinvestigators reported financial relationships with the pharmaceutical industry. Dr. Mikhael reported research funding from AbbVie, Celgene, Onyx Pharmaceuticals, and Sanofi.

SAN DIEGO – Chimeric antigen receptor T-cell therapy with tisagenlecleucel (Kymriah) is associated with a high rate of durable responses in adults with relapsed or refractory diffuse large B-cell lymphoma, an updated analysis of the JULIET trial showed.

Neil Osterweil/MDedge News

After a median follow-up of 19 months, two-thirds of adults with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who had early responses to chimeric antigen receptor (CAR) T-cell therapy with tisagenlecleucel remained in remission with no evidence of minimal residual disease, reported Richard Thomas Maziarz, MD, from the Oregon Health & Science Knight Cancer Institute in Portland, at the annual meeting of the American Society of Hematology.

“Since the previous report, no new deaths have been reported due to any cause other than patient disease progression. No treatment-related mortality was seen throughout the study, and there were three early deaths, all related to lymphoma that progressed,” he said in a briefing prior to presentation of the data in a scientific poster.

The updated study results were published simultaneously online in the New England Journal of Medicine.

JULIET then

In the phase 2, single-arm trial, investigators enrolled adults with DLBCL that had relapsed or was refractory after two or more prior lines of therapy and who were either ineligible for hematopoietic stem cell transplant or who experienced disease progression after transplant.

Interim results of the study were previously reported at the European Hematology Association Congress in 2017.

At that meeting, Gilles Salles, MD, PhD, from the University of Lyon (France), presented results of an analysis of available efficacy data on 51 patients with at least 3 months of follow-up. In this population, the best overall response rate was 59%. The 3-month overall response rate was 45%, consisting of 37% complete responses and 8% partial responses. Relapse-free survival at 6 months was 79% and all patients who had responses at 3 months continued to have responses at the time of data cutoff.

JULIET now

In the most recent analysis, completed after a median time from infusion to data cutoff of 14 months, the investigators reported on efficacy in 93 patients who received CAR T-cell infusions.

The best overall response rate, the primary endpoint, was 52%, comprising 40% complete responses and 12% partial responses. The response rates were consistent across all prognostic subgroups, including age, sex, previous response status, International Prognostic Index score at enrollment, prior therapy, molecular subtype, and other factors.

Estimated relapse-free survival 12 months after documentation of an initial response was 65%, and was 79% among patients who had complete responses.

The median duration of response had not been reached at the time of data cutoff; the median overall survival had not been reached for patients with a complete remission. Overall survival in this heavily pretreated population as a whole (all patients who received CAR T-cell infusions) was 11.1 months.

Adverse events of special interest included grade 3 or 4 cytokine release syndrome (CRS) in 23% of patients, prolonged cytopenia in 34%, infections in 19%, neurologic events in 11%, febrile neutropenia in 15%, and tumor lysis syndrome in 2%.

There were no deaths attributable to CRS or to cerebral edema, a complication of CAR T-cell therapy that appears to be related to the costimulatory molecule used in various constructs.

“Patients with relapsed or refractory DLBCL who are not eligible for high-dose therapy and hematopoietic cell transplantation or for whom such therapy was not successful have very few treatment options. For these patients, tisagenlecleucel shows promise that will need to be confirmed through larger studies with longer follow-up,” the investigators wrote in the New England Journal of Medicine.

New guidelines on the diagnosis and management of patients with primary central nervous system lymphoma (PCNSL) emphasize prompt diagnosis, aggressive treatment whenever possible, and multidisciplinary team support.

A unique aspect for hematologic cancers, the guidelines note, is that appropriate treatment for PCNSL requires input from neurology specialists.

And the guidelines recommend methotrexate-based treatment only be administered at centers experienced in delivering intensive chemotherapy.

Christopher P. Fox, MD, of the Nottingham University Hospitals NHS Trust in Nottingham, U.K., and his colleagues on behalf of the British Society for Haematology published the guidelines in BJH.

The authors incorporated findings from studies published since the society’s last comprehensive PCNSL guidelines were issued more than a decade ago.

The new guidelines provide recommendations for diagnosis and imaging, primary treatment of PCNSL, consolidation chemotherapy, follow-up, management of relapsed/refractory disease, and neuropsychological assessments.

Highlights include:

• People with suspected PCNSL must receive quick and coordinated attention from a multidisciplinary team of neurologists, hematologist-oncologists, and ocular specialists
• Histological diagnoses in addition to imaging findings should be performed
• Corticosteroids should be avoided or discontinued before biopsy, as even a short course of steroids can impede diagnosis
• Aggressive induction treatment should be chosen based on the patient’s fitness
• Patients should be offered entry into clinical trials whenever possible
• Universal screening for eye involvement should be conducted.

Primary treatment

Dr. Fox and his colleagues say definitive treatment for PCNSL—induction of remission followed by consolidation—should start within 2 weeks of diagnosis, and a treatment regimen should be chosen according to a patient’s physiological fitness, not age.

The fittest patients, who have better organ function and fewer comorbidities, should be eligible for intensive combination immuno-chemotherapy incorporating high-dose methotrexate (HD-MTX)—optimally, four cycles of HD-MTX, cytarabine, thiotepa, and rituximab.

Those deemed unfit for this regimen should be offered induction treatment with HD-MTX, rituximab, and procarbazine, the guidelines say.

If patients cannot tolerate HD-MTX, oral chemotherapy, whole-brain radiotherapy (WBRT), or corticosteroids may be used.

The authors do not recommend intrathecal chemotherapy alongside systemic CNS-directed therapy.

Response should be assessed with contrast-enhanced magnetic resonance imaging (MRI) routinely after every two cycles of HD-MTX-based therapy and at the end of remission induction.

Consolidation chemotherapy

Consolidation therapy should be initiated after induction for all patients with non-progressive disease. High-dose thiotepa-based chemotherapy with autologous stem cell transplant (ASCT) is the recommended first-line option for consolidation.

Patients ineligible for high-dose therapy followed by ASCT who have residual disease after induction therapy should be considered for WBRT. This is also the case for patients with residual disease after thiotepa-based ASCT.

However, Dr. Fox and his colleagues say WBRT consolidation is “contentious” for patients in complete response after HD-MTX regimens but ineligible for ASCT. The authors suggest carefully balancing potential improvement in progression-free survival against risks of neurocognitive toxicity.

Response to consolidation, again measured with contrast-enhanced MRI, should be carried out between 1 and 2 months after therapy is completed, and patients should be referred for neuropsychological testing to assess cognitive function.

Patients with relapsed or refractory disease should be approached with maximum urgency—the guidelines offer an algorithm for retreatment options—and offered clinical trial entry wherever possible.

Response to consolidation, again measured with contrast-enhanced MRI, should be carried out between 1 and 2 months after therapy is completed, and patients should be referred for neuropsychological testing to assess cognitive function.

Patients with relapsed or refractory disease should be approached with maximum urgency—the guidelines offer an algorithm for retreatment options—and offered clinical trial entry wherever possible.

New guidelines on the diagnosis and management of patients with primary central nervous system lymphoma (PCNSL) emphasize prompt diagnosis, aggressive treatment whenever possible, and multidisciplinary team support.

A unique aspect for hematologic cancers, the guidelines note, is that appropriate treatment for PCNSL requires input from neurology specialists.

And the guidelines recommend methotrexate-based treatment only be administered at centers experienced in delivering intensive chemotherapy.

Christopher P. Fox, MD, of the Nottingham University Hospitals NHS Trust in Nottingham, U.K., and his colleagues on behalf of the British Society for Haematology published the guidelines in BJH.

The authors incorporated findings from studies published since the society’s last comprehensive PCNSL guidelines were issued more than a decade ago.

The new guidelines provide recommendations for diagnosis and imaging, primary treatment of PCNSL, consolidation chemotherapy, follow-up, management of relapsed/refractory disease, and neuropsychological assessments.

Highlights include:

• People with suspected PCNSL must receive quick and coordinated attention from a multidisciplinary team of neurologists, hematologist-oncologists, and ocular specialists
• Histological diagnoses in addition to imaging findings should be performed
• Corticosteroids should be avoided or discontinued before biopsy, as even a short course of steroids can impede diagnosis
• Aggressive induction treatment should be chosen based on the patient’s fitness
• Patients should be offered entry into clinical trials whenever possible
• Universal screening for eye involvement should be conducted.

Primary treatment

Dr. Fox and his colleagues say definitive treatment for PCNSL—induction of remission followed by consolidation—should start within 2 weeks of diagnosis, and a treatment regimen should be chosen according to a patient’s physiological fitness, not age.

The fittest patients, who have better organ function and fewer comorbidities, should be eligible for intensive combination immuno-chemotherapy incorporating high-dose methotrexate (HD-MTX)—optimally, four cycles of HD-MTX, cytarabine, thiotepa, and rituximab.

Those deemed unfit for this regimen should be offered induction treatment with HD-MTX, rituximab, and procarbazine, the guidelines say.

If patients cannot tolerate HD-MTX, oral chemotherapy, whole-brain radiotherapy (WBRT), or corticosteroids may be used.

The authors do not recommend intrathecal chemotherapy alongside systemic CNS-directed therapy.

Response should be assessed with contrast-enhanced magnetic resonance imaging (MRI) routinely after every two cycles of HD-MTX-based therapy and at the end of remission induction.

Consolidation chemotherapy

Consolidation therapy should be initiated after induction for all patients with non-progressive disease. High-dose thiotepa-based chemotherapy with autologous stem cell transplant (ASCT) is the recommended first-line option for consolidation.

Patients ineligible for high-dose therapy followed by ASCT who have residual disease after induction therapy should be considered for WBRT. This is also the case for patients with residual disease after thiotepa-based ASCT.

However, Dr. Fox and his colleagues say WBRT consolidation is “contentious” for patients in complete response after HD-MTX regimens but ineligible for ASCT. The authors suggest carefully balancing potential improvement in progression-free survival against risks of neurocognitive toxicity.

SAN DIEGO – A shortened regimen of four cycles of rituximab plus CHOP chemotherapy was noninferior in efficacy to the standard six cycles of R-CHOP in patients aged under age 60 years with favorable-risk diffuse large B-cell lymphoma (DLBCL), and the truncated regimen was associated with about a one-third reduction in nonhematologic adverse events, investigators in the FLYER trial reported.

Among 588 evaluable patients aged younger than 60 years with favorable-prognosis diffuse DLBCL, there were no significant differences in either progression-free survival (PFS), event-free survival, or overall survival (OS) between patients who were randomly assigned to therapy with four cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone), compared with patients assigned to six cycles, reported Viola Poeschel, MD, of Saarland University in Homburg, Germany.

“Six cycles of R-CHOP led to a higher toxicity with respect to leukocytopenia and anemia, both of any grades and also of grades 3 to 4, compared to four cycles of R-CHOP,” she said in a briefing at the annual meeting of the American Society of Hematology.

For younger patients with favorable-prognosis DLBCL – defined as an age-adjusted International Prognostic Index score of 0 and low tumor burden (less than 7.5 cm) – four cycles of R-CHOP can be a new standard of care, Dr. Poeschel said.

The investigators were prompted to look at the question of a shorter R-CHOP regimen by the results of the MInT trial, in which a subpopulation of favorable-prognosis DLBCL had a 3-year PFS rate of 89% (Lancet Oncol. 2006 May;7[5]379-91). The FLYER trial was designed as a noninferiority study to see whether in a similar group of patients reducing the number of R-CHOP cycles could maintain efficacy while reducing toxicity.

At a median follow-up of 66 months, the PFS rate, the primary endpoint, was 94% in the R-CHOP 6 group, compared with 96% for R-CHOP 4.

“As the lower limit of the 95% confidence interval of our experimental arm was 94%, it is shown that it is definitely noninferior to the standard arm, six cycles of R-CHOP,” Dr. Poeschel said.

Similarly, the rate of 3-year OS was 98% in the six-cycle group, compared with 99% in the four-cycle group, and the survival curves were virtually superimposable out to more than 10 years of follow-up.

R-CHOP 6 was associated with more frequent hematologic adverse events, compared with R-CHOP 4, with leukopenia of any grade occurring in 237 versus 171 patients, respectively, and grade 3 or 4 events occurring in 110 versus 80 patients, respectively.

Any grade anemia occurred in 172 patients assigned to six cycles versus 107 assigned to four cycles. Rates of grade 3-4 anemia and thrombocytopenia of any grade or of grade 3-4 were similar between the groups.

Nonhematologic adverse events of any grade or of grade 3 or 4 that were more frequent with R-CHOP 6 versus R-CHOP 4 included all events considered together, paresthesias, nausea, infection, vomiting, and mucositis.

As noted before, the total number of nonhematologic adverse events was reduced by about one-third.

“We are certainly always looking for ways to make treatments easier for our patients to reduce adverse effects, and certainly for this subgroup of patients it appears that we can make their treatment shorter and have less burden but equivalent efficacy,” commented David Steensma, MD, from the Dana-Farber Cancer Institute/Harvard Cancer Center in Boston, who moderated the briefing.

Dr. Steensma and Dr. Poeschel both cautioned that the results of the study pertain only to those patients with DLBCL who are younger and have favorable-prognosis disease.

“We can’t extend it to other subtypes of large cell lymphoma, but that’s always a laudable goal, so I think this will immediately influence clinical practice,” Dr. Steensma said.

The study was sponsored by the German High-Grade Non-Hodgkin’s Lymphoma Study Group. Dr. Poeschel reporteed travel grants from Roche and Amgen. Dr. Steensma reported no disclosures relevant to the study.

About one in seven patients with newly diagnosed multiple myeloma who are eligible for transplant are living at least as long as similar individuals in the general population, finds a retrospective cohort study of the International Myeloma Working Group. That figure may be even higher today because more than 90% of patients in the study – the largest yet to look at outcome predictors in this population – were treated in the era before novel therapies became available.

Investigators led by Saad Z. Usmani, MD, director/chief of plasma cell disorders and director of clinical research (hematologic malignancies) at the Levine Cancer Institute/Atrium Health in Charlotte, N.C., studied 7,291 patients with newly diagnosed multiple myeloma who were up to 75 years old and eligible for high-dose melphalan and autologous stem cell transplant. The patients were treated in clinical trials in 10 countries.

Compared with counterparts who did not achieve complete response 1 year after diagnosis, patients who did had better median progression-free survival (3.3 vs. 2.6 years; P less than .0001) and median overall survival (8.5 vs. 6.3 years; P less than .0001), according to study results report in Blood Cancer Journal.

The investigators next performed multivariate analyses to assess clinical variables at diagnosis associated with 10-year survival as compared with 2-year death.

Results here indicated that patients were less likely to be alive at 10 years if they were older than 65 years (odds ratio for death, 1.87; P = .002); had an immunoglobulin A isotype (OR, 1.53; P = .004); had a low albumin level, defined as less than 3.5 g/dL (OR, 1.36; P = .023); had an elevated beta₂-microglobulin level, defined as at least 3.5 mg/dL (OR, 1.86; P less than .001); had a higher serum creatinine level, defined as at least 2 mg/dL (OR, 1.77; P = .005); had a lower hemoglobin level, defined as less than 10 g/dL (OR, 1.55; P = .003); or had a lower platelet count, defined as less than 150,000/μL (OR, 2.26; P less than .001).

Cytogenetic abnormalities did not independently predict long-term survival, but these abnormalities were obtained only by conventional band karyotyping and were not available for some patients.

Overall, the cohort had a relative survival of about 0.9 when compared with the matched general population. With follow-up out to about 20 years, the cure fraction (proportion achieving or exceeding expected survival when compared with the matched general population) was 14.3%.

Identification of early complete response as a predictor of long-term survival “underscores the importance of depth of response as we explore novel regimens for newly diagnosed [multiple myeloma] along with [minimal residual disease] endpoints,” Dr. Usmani and his colleagues wrote while acknowledging that the patients studied were a selected group eligible for transplant and treated on trials.

Recent therapeutic advances “have reignited the debate on possible functional curability of a subset MM patients,” they noted. “[T]here are perhaps more effective drugs and drug classes in the clinician’s armamentarium than [were] available for MM patients being treated in the 1990s or even early 2000s. This may mean that the depth of response after induction therapy may continue to improve over time, potentially further improving the PFS/OS of [the] biologic subset who previously achieved [partial response] yet had good long-term survival.”
