The U.S. Food and Drug Administration (FDA) has approved a new indication for brentuximab vedotin (ADCETRIS®) less than 2 weeks after receiving the completed supplemental biologics license application (sBLA).

Brentuximab vedotin is now approved for use in combination with cyclophosphamide, doxorubicin, and prednisone (CHP) to treat adults with previously untreated systemic anaplastic large-cell lymphoma or other CD30-expressing peripheral T-cell lymphomas (PTCLs), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified.

The FDA granted priority review and breakthrough therapy designation to the sBLA for brentuximab vedotin in this indication.

The FDA reviewed the sBLA under the Real-Time Oncology Review Pilot Program, which led to approval less than 2 weeks after the application was submitted in full.

“The Real-Time Oncology Review program allows the FDA to access key data prior to the official submission of the application, allowing the review team to begin their review earlier and communicate with the sponsor prior to the application’s actual submission,” said Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products.

“When the sponsor submits the completed application, the review team will already be familiar with the data and be able to conduct a more efficient, timely, and thorough review.”

Trial data

The FDA’s approval is based on results from the phase 3 ECHELON-2 trial (NCT01777152).

Seattle Genetics, Inc. and Takeda Pharmaceutical Company Limited announced results from this trial last month. Additional results are scheduled to be presented at the 2018 ASH Annual Meeting (abstract 997).

The trial enrolled 452 patients with CD30-positive PTCL. The patients were randomized to receive brentuximab vedotin (BV) plus CHP or cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP).

The objective response rate was 83% in the BV-CHP arm and 72% in the CHOP arm (P=0.003). The complete response rate was 68% and 56%, respectively (P=0.007).

Progression-free survival was significantly better in the BV-CHP arm than in the CHOP arm (hazard ratio=0.71; P=0.011), as was overall survival (hazard ratio=0.66; P=0.024).

The most common adverse events of any grade that occurred in at least 20% of patients in the BV-CHP arm were peripheral neuropathy, nausea, diarrhea, neutropenia, lymphopenia, fatigue, mucositis, constipation, alopecia, pyrexia, vomiting, and anemia.

Serious adverse events occurring in at least 2% of patients in the BV-CHP arm included febrile neutropenia, pneumonia, pyrexia, and sepsis.

Results of this trial suggest prophylactic growth factors should be given to previously untreated PTCL patients receiving BV-CHP (starting at cycle 1).

Long-term data suggest R-CHOP can be effective as first-line treatment for patients with follicular lymphoma (FL).

In a phase 2-3 trial, investigators compared R-CHOP-21 and R-CHOP-14 in a cohort of patients with indolent lymphomas, most of whom had FL.

Ten-year survival rates were similar between the R-CHOP-21 and R-CHOP-14 groups, with progression-free survival (PFS) rates of 33% and 39%, respectively, and overall survival (OS) rates of 81% and 85%, respectively.

The investigators did note that 9% of patients in each treatment group developed secondary malignancies, and grade 3 infections were a concern as well.

Takashi Watanabe, MD, PhD, of Mie University in Japan, and his colleagues reported these results in The Lancet Haematology.

The trial (JCOG0203) included 300 patients with stage III or IV indolent B-cell lymphomas from 44 Japanese hospitals.

Most patients (n=248) had grade 1-3a FL, 17 had grade 3b FL, 6 had marginal zone lymphoma, 6 had diffuse large B-cell lymphoma, 4 had mantle cell lymphoma, 2 had small lymphocytic lymphoma, 1 had plasmacytoma, 13 had other indolent B-cell lymphomas, and 3 had other lymphomas.

The patients were randomly assigned to receive six cycles of R-CHOP 21 (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone every 3 weeks) or R-CHOP 14 (R-CHOP every 2 weeks with granulocyte-colony stimulating factor support). Neither group received rituximab maintenance.

Overall results

The median follow-up was 11.2 years (interquartile range, 10.1 to 12.7 years).

The 10-year PFS was 33% in the R-CHOP-21 group and 39% in the R-CHOP-14 group (hazard ratio=0.89). The 10-year OS was 81% and 85%, respectively (hazard ratio=0.87).

At 10 years, the incidence of secondary malignancies was 9% in both the R-CHOP-21 group (14/148) and the R-CHOP-14 group (14/151).

The most frequent solid tumor malignancies were stomach (n=5), lung (n=4), colon (n=3), bladder (n=2), and prostate (n=2) cancers. Hematologic malignancies included myelodysplastic syndromes (n=6), acute myeloid leukemia (n=2), acute lymphoblastic leukemia (n=1), and chronic myeloid leukemia (n=1).

There were nine deaths from secondary malignancies, four in the R-CHOP-21 group and five in the R-CHOP-14 group.

The rate of grade 3 adverse events was 18% (n=53) for the entire cohort. Grade 3 infections occurred in 23% of the R-CHOP-21 group and 12% of the R-CHOP-14 group.

Focus on grade 1-3a FL

Among the 248 patients with grade 1-3a FL, the PFS (for both treatment groups) was 45% at 5 years, 39% at 8 years, and 36% at 10 years. The OS was 94% at 5 years, 87% at 8 years, and 85% at 10 years.

Histological transformation was observed in 11% of the patients who had grade 1-3a FL at enrollment. The cumulative incidence of histological transformation was 2.4% at 3 years, 3.2% at 5 years, 8.5% at 8 years, and 9.3% at 10 years.

Secondary malignancies occurred in 10% (12/125) of the R-CHOP-21 group and 11% (13/123) of the R-CHOP-14 group.

The cumulative incidence of hematologic secondary malignancies at 10 years was 2.9%.

The investigators noted that the actual incidence of secondary solid tumors or hematologic malignancies apart from the setting of autologous stem cell transplants is not known. They emphasized that patients should be followed beyond 10 years to ensure the risk of secondary malignancies is not underestimated.

“Clinicians choosing a first-line treatment for patients with follicular lymphoma should be cautious of secondary malignancies caused by immunochemotherapy and severe complications of infectious diseases in the long-term follow-up—both of which could lead to death,” the investigators wrote.

This study was supported by the Ministry of Health, Labour and Welfare of Japan and the National Cancer Center Research and Development Fund of Japan.

Dr. Wantanabe has received honoraria from Bristol-Myers Squibb, Takeda, Taisho Toyama, Celgene, Nippon Shinyaku, and Novartis and funding resources from TakaraBio and United Immunity to support the Department of Immuno-Gene Therapy at Mie University. Multiple co-authors reported similar relationships.

Micrograph showing DLBCL

The U.S. Food and Drug Administration (FDA) has granted fast track designation to selinexor for the treatment of diffuse large B-cell lymphoma (DLBCL).

The designation is for selinexor to treat DLBCL patients who have received at least two prior therapies and are not eligible for high-dose chemotherapy with stem cell rescue or chimeric antigen receptor T-cell therapy.

Selinexor is being studied in the phase 2b SADAL trial (NCT02227251), which is enrolling patients with relapsed or refractory DLBCL who have received two to five prior therapies and are not eligible for stem cell transplant.

Top-line results from this trial are scheduled to be presented at the 2018 ASH Annual Meeting (abstract 1677).

Selinexor is an oral selective inhibitor of nuclear export (SINE) compound being developed by Karyopharm Therapeutics Inc.

The company previously received fast track designation for selinexor to treat patients with penta-refractory multiple myeloma who have received at least three prior lines of therapy.

The FDA says its fast track program is designed to facilitate the development and expedite the review of products that are intended to treat serious conditions and have the potential to address unmet medical needs.

Fast track designation provides developers with greater access to the FDA as well as eligibility for accelerated approval, priority review, and rolling review.

“The receipt of fast track designation from the FDA for selinexor in relapsed DLBCL underscores the great unmet medical need for this aggressive form of lymphoma,” said Sharon Shacham, PhD, founder, president, and chief scientific officer of Karyopharm.

“Pending positive results from the phase 2b SADAL study, we plan to submit a second NDA [new drug application] to the FDA in the first half of 2019, with a request for accelerated approval, for oral selinexor as a potential new treatment for patients with relapsed or refractory DLBCL.”

Last month, the FDA accepted a new drug application for selinexor as a treatment for penta-refractory multiple myeloma. The agency granted the application priority review and set an action date of April 6, 2019.

follicular lymphoma

The combination of Hu5F9-G4 (5F9) and rituximab was considered safe and produced durable complete responses (CRs) in patients with relapsed or refractory non-Hodgkin lymphoma (NHL) in a phase 1b trial.

Mainly low-grade adverse events (AEs) were observed with rituximab and 5F9, a macrophage-activating immune checkpoint inhibitor blocking CD47.

In addition, the combination produced an objective response rate (ORR) of 50% and a CR rate of 36%.

Most of the responses were ongoing at the time of data cutoff.

“It was very gratifying to see how the treatment was well-tolerated and showed a clinically meaningful response,” said Ranjana Advani, MD, of Stanford University in California.

She and her colleagues reported these results in The New England Journal of Medicine.

The study included 22 patients with relapsed or refractory NHL. Fifteen had diffuse large B-cell lymphoma (DLBCL), and seven had follicular lymphoma (FL).

The patients had received a median of four prior therapies (range, 2-10). Twenty-one patients had disease that was refractory to rituximab (all FL and 14 DLBCL patients).

All patients received 5F9 starting with a priming dose of 1 mg/kg followed by weekly maintenance doses of 10 to 30 mg/kg in three dose-escalation cohorts. The treatment was given until disease progression or lack of clinical benefit.

Patients received rituximab at 375 mg/m² weekly starting on the second week of the first cycle and then monthly for cycles two through six.

Results

The most common treatment-related AEs were chills (41%), headache (41%), anemia (41%), and infusion-related reactions (36%).

Serious AEs included infections (18%), anemia (4.5%), dyspnea (4.5%), pyrexia (4.5%), lactic acidosis (4.5%), retroperitoneal mass (4.5%), pulmonary embolism (4.5%), and infusion-related reaction (4.5%).

For the entire cohort, the ORR was 50% (n=11), and the CR rate was 36% (n=8).

Among DLBCL patients, the ORR was 40% (n=6), and the CR rate was 33% (n=5). In FL patients, the ORR was 71% (n=5), and the CR rate was 43% (n=3).

The median duration of response was not reached in either disease cohort. The median follow-up was 6.2 months for DLBCL and 8.1 months for FL.

Ten of 11 responders (91%) were still in response at the time of data cutoff.

The researchers said a phase 2 trial of 5F9 plus rituximab in relapsed or refractory B-cell NHL is ongoing.

The phase 1b study was supported by Forty Seven, Inc., and the Leukemia and Lymphoma Society. Dr. Advani reported disclosures related to Forty Seven, Inc., Bristol-Myers Squibb, Pharmacyclics, Seattle Genetics, and Roche/Genentech, among others.

The study included 22 patients with relapsed or refractory NHL. Fifteen had diffuse large B-cell lymphoma (DLBCL), and seven had follicular lymphoma (FL).

The patients had received a median of four prior therapies (range, 2-10). Twenty-one patients had disease that was refractory to rituximab (all FL and 14 DLBCL patients).

All patients received 5F9 starting with a priming dose of 1 mg/kg followed by weekly maintenance doses of 10 to 30 mg/kg in three dose-escalation cohorts. The treatment was given until disease progression or lack of clinical benefit.

Patients received rituximab at 375 mg/m² weekly starting on the second week of the first cycle and then monthly for cycles two through six.

Results

The most common treatment-related AEs were chills (41%), headache (41%), anemia (41%), and infusion-related reactions (36%).

Serious AEs included infections (18%), anemia (4.5%), dyspnea (4.5%), pyrexia (4.5%), lactic acidosis (4.5%), retroperitoneal mass (4.5%), pulmonary embolism (4.5%), and infusion-related reaction (4.5%).

For the entire cohort, the ORR was 50% (n=11), and the CR rate was 36% (n=8).

Among DLBCL patients, the ORR was 40% (n=6), and the CR rate was 33% (n=5). In FL patients, the ORR was 71% (n=5), and the CR rate was 43% (n=3).

The median duration of response was not reached in either disease cohort. The median follow-up was 6.2 months for DLBCL and 8.1 months for FL.

Ten of 11 responders (91%) were still in response at the time of data cutoff.

The researchers said a phase 2 trial of 5F9 plus rituximab in relapsed or refractory B-cell NHL is ongoing.

The phase 1b study was supported by Forty Seven, Inc., and the Leukemia and Lymphoma Society. Dr. Advani reported disclosures related to Forty Seven, Inc., Bristol-Myers Squibb, Pharmacyclics, Seattle Genetics, and Roche/Genentech, among others.

The combination of Hu5F9-G4 (5F9) and rituximab was considered safe and produced durable complete responses (CRs) in patients with relapsed or refractory non-Hodgkin lymphoma (NHL) in a phase 1b trial.

Mainly low-grade adverse events (AEs) were observed with rituximab and 5F9, a macrophage-activating immune checkpoint inhibitor blocking CD47.

In addition, the combination produced an objective response rate (ORR) of 50% and a CR rate of 36%.

Most of the responses were ongoing at the time of data cutoff.

Sandoz has decided not to pursue U.S. approval for its rituximab product (GP2013), a proposed biosimiliar of Rituxan/Mabthera.

GP2013 (Rixathon, Riximyo) is already approved outside the U.S.

Sandoz was seeking U.S. approval of GP2013 for all the same indications as the reference product—B-cell non-Hodgkin lymphoma, chronic lymphocytic leukemia, rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, and pemphigus vulgaris.

The U.S. Food and Drug Administration (FDA) had accepted the biologics license application (BLA) for GP2013 in September 2017.

In May of this year, the FDA issued a complete response letter saying it could not approve GP2013. The agency also requested additional information to complement the BLA submission for GP2013.

At the time of the complete response letter, Sandoz said it was still committed to bringing GP2013 to the U.S. market. Now, the company’s position has changed.

“We appreciate the important conversations with the FDA, which have provided specific requirements for our potential U.S. biosimilar rituximab, but believe the patient and marketplace needs in the U.S. will be satisfied before we can generate the data required,” said Stefan Hendriks, global head of biopharmaceuticals at Sandoz.

“We are disappointed to have to make this decision and stand behind the safety, efficacy, and quality of our medicine, which met the stringent criteria for approval in the European Union, Switzerland, Japan, New Zealand, and Australia.”

The BLA for GP2013 was supported, in part, by the ASSIST-FL trial (NCT01419665), in which researchers compared GP2013 to the reference product. Results from this trial were published in The Lancet Haematology in July 2017.

The phase 3 trial included adults with previously untreated, advanced stage follicular lymphoma. Patients received 8 cycles of cyclophosphamide, vincristine, and prednisone with either GP2013 or reference rituximab. Responders then received GP2013 or rituximab monotherapy as maintenance for up to 2 years.

At a median follow-up of 11.6 months, the overall response rate was 87% (271/311) in the GP2013 arm and 88% in the rituximab arm (274/313). Complete response rates were 15% (n=46) and 13% (n=42), respectively.

Rates of adverse events (AEs) were 93% in the GP2013 arm and 91% in the rituximab arm. Rates of serious AEs were 23% and 20%, respectively. The rate of discontinuation due to AEs was 7% in both arms.

The most common AE was neutropenia, which occurred in 26% of patients in the GP2013 arm and 30% of those in the rituximab arm in the combination phase. Rates of neutropenia in the maintenance phase were 10% and 6%, respectively.

Health Canada has granted conditional approval for pralatrexate (Folotyn®) to treat relapsed or refractory peripheral T-cell lymphoma (PTCL).

Pralatrexate received a Notice of Compliance with Conditions (NOC/c), which is an approval granted on the basis of promising evidence of clinical effectiveness that must be verified in additional clinical trials.

To be approved under Health Canada’s NOC/c policy, a product must be intended for the treatment, prevention, or diagnosis of a serious, life-threatening, or severely debilitating illness.

In addition, the product must have demonstrated promising benefit, be of high quality, have an acceptable safety profile based on a benefit/risk assessment, and either respond to a serious unmet need or provide a significant improvement over existing therapies.

The NOC/c for pralatrexate is based on response rates in the single-arm, phase 2 PROPEL trial. Results from PROPEL were published in the Journal of Clinical Oncology in 2011.

The trial enrolled 115 patients with relapsed or refractory PTCL who had received a median of three (range, 1-12) prior systemic therapies.

The patients received pralatrexate once weekly at a dose of 30 mg/m² for 6 weeks in 7-week cycles until disease progression or unacceptable toxicity.

In the 109 evaluable patients, the response rate was 29% (32/109). The complete response rate was 11% (n=12), and the partial response rate was 18% (n=20).

The median duration of response was 10.1 months, the median progression-free survival was 3.5 months, and the median overall survival was 14.5 months.

The most common adverse events (AEs) were mucositis (71%), thrombocytopenia (41%), nausea (41%), fatigue (36%), pyrexia (34%), anemia (34%), constipation (34%), edema (31%), cough (29%), epistaxis (26%), vomiting (25%), neutropenia (25%), and diarrhea (23%).

The most common grade 3/4 AEs were thrombocytopenia (32%), mucositis (22%), neutropenia (22%), and anemia (18%).

The product monograph for pralatrexate contains a boxed warning highlighting the risk of AEs associated with pralatrexate use, including dermatologic reactions, bone marrow suppression, infection, mucosal inflammation, tumor lysis syndrome, potential fetal harm, and pulmonary toxicity.

The product monograph is available for download from the website of Servier Canada, the company marketing pralatrexate in Canada.

The European Commission (EC) has approved a new indication for venetoclax (Venclyxto®).

The drug is now approved for use in combination with rituximab to treat patients with relapsed/refractory chronic lymphocytic leukemia (CLL) who have received at least one prior therapy.

The approval is valid in all member states of the European Union as well as Iceland, Liechtenstein, and Norway.

The EC’s approval is based on results from the phase 3 MURANO trial, which were published in The New England Journal of Medicine in March.

The trial included 389 CLL patients who were randomized to receive venetoclax plus rituximab (VEN+R) or bendamustine plus rituximab (B+R). The median follow-up was 23.8 months.

According to an independent review committee, the overall response rate was 92.3% in the VEN+R arm and 72.3% in the B+R arm. The investigator-assessed overall response rates were 93.3% and 67.7%, respectively.

According to investigators, the median progression-free survival (PFS) was not reached in the VEN+R arm and was 17.0 months in the B+R arm (hazard ratio [HR]=0.17; P<0.0001).

According to the independent review committee, the median PFS was not reached in the VEN+R arm and was 18.1 months in the B+R arm (HR=0.20; P<0.0001).

• Tumor lysis syndrome (3.1% and 1.1%)
• Hypotension (0% and 2.7%)
• Hyperglycemia (2.1% and 0%)
• Hypogammaglobulinemia (2.1% and 0%).

Serious AEs with at least a 2% difference in incidence between the arms (in the VEN+R and B+R arms, respectively) were:

• Pneumonia (8.2% and 8.0%)
• Febrile neutropenia (3.6% and 8.5%)

• Tumor lysis syndrome (2.1% and 0.5%)
• Hypotension (0% and 2.7%).

Fatal AEs occurred in 5.2% of patients in the VEN+R arm and 5.9% in the B+R arm.

Fatal AEs in the VEN+R arm included pneumonia (n=3), sepsis (n=1), thrombocytopenia (n=1), cardiac failure (n=1), myocardial infarction (n=1), sudden cardiac death (n=1), colorectal cancer (n=1), status epilepticus (n=1), and acute respiratory failure (n=1). Two cases of pneumonia occurred in the setting of progression/Richter’s transformation.

A retrospective study has revealed new potential risk factors for chemotherapy-induced febrile neutropenia (FN) in patients with solid tumors and non-Hodgkin lymphoma (NHL).

Researchers found the timing and duration of corticosteroid use were both associated with FN.

The team also observed “marginal” associations between FN and certain dermatologic and mucosal conditions as well as the use of intravenous (IV) antibiotics before chemotherapy.

On the other hand, there was no association between oral antibiotic use and FN or between radiation therapy (RT) and FN.

Chun Rebecca Chao, PhD, of Kaiser Permanente Southern California in Pasadena, and her colleagues reported these findings in JNCCN.

“Febrile neutropenia is life-threatening and often requires hospitalization,” Dr. Chao noted. “Furthermore, FN can lead to chemotherapy dose delay and dose reduction, which, in turn, negatively impacts antitumor efficacy. However, it can be prevented if high-risk individuals are identified and treated prophylactically.”

With this in mind, Dr. Chao and her colleagues set out to identify novel risk factors for FN by analyzing 15,971 patients who were treated with myelosuppressive chemotherapy at Kaiser Permanente Southern California between 2000 and 2009.

Patients had been diagnosed with NHL (n=1,617) or breast (n=6,323), lung (n=3,584), colorectal (n=3,062), ovarian (n=924), or gastric (n=461) cancers.

In all, 4.3% of patients developed FN during their first cycle of chemotherapy.

Corticosteroid use

The researchers found corticosteroid use was associated with an increased risk of FN in a propensity score-adjusted (PSA) model (adjusted for age, sex, socioeconomic factors, comorbidities, etc.). The hazard ratio (HR) was 1.53 (95% CI, 1.17-1.98; P<0.01) for patients who received corticosteroids.

A longer duration of corticosteroid use was associated with a greater risk of FN. The adjusted HR (compared to no corticosteroid use) was:

• 1.78 for corticosteroid treatment lasting less than 15 days (P<0.01)
• 1.84 for treatment lasting 15 to 29 days (P<0.01)
• 2.27 for treatment lasting 30 to 44 days (P<0.01)
• 2.86 for treatment lasting 45 to 90 days (P<0.01).

More recent corticosteroid use was associated with a greater risk of FN as well. The adjusted HR was:

• 1.88 for corticosteroid treatment less than 15 days before chemotherapy (P<0.01)
• 1.13 for treatment 15 to 29 days before chemotherapy (P=0.72)
• 1.22 for treatment 30 to 44 days before chemotherapy (P=0.66)
• 1.41 for treatment 45 to 90 days before chemotherapy (P=0.32).

“One way to reduce the incidence rate for FN could be to schedule prior corticosteroid use and subsequent chemotherapy with at least 2 weeks between them, given the magnitude of the risk increase and prevalence of this risk factor,” Dr. Chao said.

Other potential risk factors

The researchers found a “marginally” increased risk of FN in patients with certain dermatologic conditions (dermatitis, psoriasis, pruritus, etc.) and mucosal conditions (gastritis, stomatitis, mucositis, etc.).

In the PSA model, the HR was 1.40 (95% CI, 0.98-1.93; P=0.05) for patients with these conditions.

IV antibiotic use was also found to be marginally associated with an increased risk of FN in a restricted analysis covering patients treated in 2008 and 2009. In the PSA model, the HR was 1.35 (95% CI, 0.97-1.87; P=0.08).

On the other hand, there was no association between FN and oral antibiotic use in the restricted analysis. In the PSA model, the HR was 1.07 (95% CI, 0.77-1.48; P=0.70) for patients who received oral antibiotics.

Dr. Chao and her colleagues said these results suggest IV antibiotics may have a more profound impact than oral antibiotics on the balance of bacterial flora and other immune functions. Another possible explanation is that patients who received IV antibiotics were generally sicker and more prone to severe infection than patients who received oral antibiotics.

As with oral antibiotics, the researchers found no association between FN and the following factors (with the PSA model):

• Prior surgery (HR=0.89; 95% CI, 0.72-1.11; P=0.30)
• Prior RT (HR=0.91; 95% CI, 0.64-1.27; P=0.61)
• Concurrent RT (HR=1.32; 95% CI, 0.69-2.37; P=0.37).

The researchers noted that they did not account for radiation field or dose in this study, so additional evaluation of RT as a risk factor is needed.

In closing, Dr. Chao and her colleagues said these results suggest cor­ticosteroid use, IV antibiotics, and certain dermatologic and mucosal conditions should be tak­en into consideration when monitoring patients receiving myelosuppressive chemotherapy and when evaluating the need for prophylactic granulocyte colony-stimulating factor or chemotherapy dose reduction.

Dr. Chao and her colleagues received funding from Amgen, Inc., to perform this study.

Final results of a phase 3 trial suggest bortezomib plus rituximab and chemotherapy can significantly improve overall survival (OS) in transplant-ineligible patients with newly diagnosed mantle cell lymphoma (MCL).

In the LYM-3002 trial, researchers compared bortezomib plus rituximab, cyclophosphamide, doxorubicin, and prednisone (VR-CAP) to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP).

The median OS was significantly longer in patients who received VR-CAP than in those who received R-CHOP—90.7 months and 55.7 months, respectively.

This survival benefit was observed in patients with low- and intermediate-risk disease but not high-risk disease.

Tadeusz Robak, MD, of the Medical University of Lodz in Poland, and his colleagues reported these results in The Lancet Oncology alongside a related commentary.

The LYM-3002 trial began more than a decade ago, and initial results were published in 2015. At that time, the VR-CAP group showed a significant increase in progression-free survival compared with the R-CHOP group.

The final analysis of LYM-3002 included 268 of the original 487 MCL patients. Twenty-three percent of patients in the VR-CAP group (n=32) discontinued due to death, as did 40% of patients in the R-CHOP group (n=51). The main cause of death was progression—29% and 14%, respectively.

Among the 268 patients in the final analysis, 140 belonged to the VR-CAP group and 128 to the R-CHOP group. The patients’ median age was 66 (range, 26-83), 71% (n=190) were male, 74% (n=199) had stage IV disease, and 31% were classified as high risk based on the MCL-specific International Prognostic Index (MIPI).

About half of patients received therapies after the trial interventions (n=255, 52%)—43% (n=104) in the VR-CAP group and 62% (n=151) in the R-CHOP group. Most patients received subsequent antineoplastic therapy—77% (n=80) and 81% (n=123), respectively—and more than half received rituximab as second-line therapy—53% (n=55) and 59% (n=89), respectively.

Results

At a median follow-up of 82.0 months, the median OS was significantly longer in the VR-CAP group than in the R-CHOP group—90.7 months (95% CI, 71.4 to not estimable) and 55.7 months (95% CI, 47.2 to 68.9), respectively (hazard ratio [HR]=0.66 [95% CI, 0.51–0.85]; P=0.001).

The 4-year OS was 67.3% in the VR-CAP group and 54.3% in the R-CHOP group. The 6-year OS was 56.6% and 42.0%, respectively.

The researchers noted that VR-CAP was associated with significantly improved OS among patients in the low-risk and intermediate-risk MIPI categories but not in the high-risk category.

In the low-risk cohort, the median OS was 81.7 months in the R-CHOP group and not estimable in the VR-CAP group (HR=0.54 [95% CI, 0.30–0.95]; P≤0.05).

In the intermediate-risk cohort, the median OS was 62.2 months in the R-CHOP group and not estimable in the VR-CAP group (HR=0.55 [95% CI, 0.36–0.85]; P≤0.01).

In the high-risk cohort, the median OS was 37.1 months in the R-CHOP group and 30.4 months in the VR-CAP group (HR=1.02 [95% CI, 0.69–1.50]).

The researchers reported three new adverse events in the final analysis—grade 4 lung adenocarcinoma and grade 4 gastric cancer in the VR-CAP group as well as grade 2 pneumonia in the R-CHOP group.

The team acknowledged that a key limitation of this study was that rituximab was not given as maintenance since it was not considered standard care at the time of study initiation.

Moving forward, Dr. Robak and his colleagues recommend that bortezomib be investigated in combination with newer targeted therapies in order to establish best practice for treating MCL.

The LYM-3002 study was sponsored by Janssen Research & Development. The study authors reported financial ties to Janssen, Celgene, Ipsen, Johnson & Johnson, Novartis, and other companies.

Micrograph showing WM

NEW YORK—The BTK inhibitor zanubrutinib has demonstrated “robust activity” and “good tolerability” in patients with Waldenström’s macroglobulinemia (WM), according to an investigator.

In a phase 1 trial, zanubrutinib produced an overall response rate (ORR) of 92%, and the estimated 12-month progression-free survival (PFS) rate was 89%.

Most adverse events (AEs) in this trial were grade 1 or 2 in severity, although the incidence of serious AEs was 42%.

Constantine Tam, MD, of the Peter MacCallum Cancer Center in Victoria, Australia, presented these results at the 10th International Workshop on Waldenström’s Macroglobulinemia.

The trial is sponsored by BeiGene, Ltd., the company developing zanubrutinib.

The trial (NCT02343120) includes patients with WM and other B-cell malignancies. As of July 24, 2018, 77 patients with treatment-naïve or relapsed/refractory WM had been enrolled.

Seventy-three patients were evaluable for efficacy in this analysis, and the median follow-up time was 22.5 months (range, 4.1-43.9).

At the time of the data cutoff, 62 patients remained on study treatment. Four patients (3%) discontinued treatment due to disease progression, and one patient remains on treatment post-progression.

Efficacy

The median time to response was 85 days (range, 55-749).

The ORR was 92% (67/73), and the major response rate (MRR) was 82%. Forty-one percent of patients achieved a very good partial response (VGPR), defined as a greater than 90% reduction in baseline immunoglobulin M (IgM) levels and improvement of extramedullary disease by computed tomography.

The median IgM decreased from 32.7 g/L (range, 5.3-91.9) at baseline to 8.2 g/L (range, 0.3-57.8). The median hemoglobin increased from 8.85 g/dL (range, 6.3-9.8) to 13.4 g/dL (range, 7.7-17.0) among 32 patients with hemoglobin less than 10 g/dL at baseline.

MYD88 genotype was known in 63 patients. In the subset known to have the MYD88L265P mutation (n=54), the ORR was 94%, the MRR was 89%, and the VGPR rate was 46%.

In the nine patients known to have wild-type MYD88 (a genotype that, historically, has had sub-optimal response to BTK inhibition), the ORR was 89%, the MRR was 67%, and the VGPR rate was 22%.

The 12-month PFS was estimated to be 89%, and the median PFS had not been reached.

Safety

The most frequent AEs of any attribution were petechiae/purpura/contusion (43%), upper respiratory tract infection (42%), cough (17%), diarrhea (17%), constipation (16%), back pain (16%), and headache (16%).

Grade 3-4 AEs of any attribution reported in three or more patients included neutropenia (9%), anemia (7%), hypertension (5%), basal cell carcinoma (5%), renal and urinary disorders (4%), and pneumonia (4%).

Serious AEs were seen in 32 patients (42%). Events in five patients (7%) were considered possibly related to zanubrutinib treatment—febrile neutropenia, colitis, atrial fibrillation, hemothorax, and pneumonia.

Nine patients (12%) discontinued study treatment due to AEs, but all of these events were considered unrelated to treatment. The AEs (n=1 for each) included abdominal sepsis (fatal), gastric adenocarcinoma (fatal), septic shoulder, worsening bronchiectasis, scedosporium infection, prostate adenocarcinoma, metastatic neuroendocrine carcinoma, acute myeloid leukemia, and breast cancer.

Atrial fibrillation/flutter occurred in four patients (5%), and major hemorrhage was observed in two patients (3%).

“We are encouraged that additional data on zanubrutinib in patients with WM confirms the initially reported experience, with consistent demonstration of robust activity and good tolerability,” Dr. Tam said.

“We are hopeful that zanubrutinib, if approved, could potentially provide an important new treatment option to patients with WM and other hematologic malignancies.”

Dr. Tam reported financial relationships with BeiGene and other companies.

NEW YORK—The BTK inhibitor zanubrutinib has demonstrated “robust activity” and “good tolerability” in patients with Waldenström’s macroglobulinemia (WM), according to an investigator.

In a phase 1 trial, zanubrutinib produced an overall response rate (ORR) of 92%, and the estimated 12-month progression-free survival (PFS) rate was 89%.

Most adverse events (AEs) in this trial were grade 1 or 2 in severity, although the incidence of serious AEs was 42%.

Constantine Tam, MD, of the Peter MacCallum Cancer Center in Victoria, Australia, presented these results at the 10th International Workshop on Waldenström’s Macroglobulinemia.

The trial is sponsored by BeiGene, Ltd., the company developing zanubrutinib.

The trial (NCT02343120) includes patients with WM and other B-cell malignancies. As of July 24, 2018, 77 patients with treatment-naïve or relapsed/refractory WM had been enrolled.

Seventy-three patients were evaluable for efficacy in this analysis, and the median follow-up time was 22.5 months (range, 4.1-43.9).

At the time of the data cutoff, 62 patients remained on study treatment. Four patients (3%) discontinued treatment due to disease progression, and one patient remains on treatment post-progression.
