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).

Investigators said the 2-year PFS rate was 84.9% in the VEN+R arm and 36.3% in the B+R arm.

They said the 2-year overall survival rates were 91.9% and 86.6%, respectively (HR=0.48; P<0.0001). The median overall survival was not reached in either arm.

Grade 3/4 adverse events (AEs) with at least a 2% difference in incidence between the treatment arms (in the VEN+R and B+R arms, respectively) included:

• Neutropenia (57.7% and 38.8%)
• Infections and infestations (17.5% and 21.8%)
• Anemia (10.8% and 13.8%)
• Thrombocytopenia (5.7% and 10.1%)
• Febrile neutropenia (3.6% and 9.6%)
• Pneumonia (5.2% and 8.0%)
• Infusion-related reactions (1.5% and 5.3%)
• 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%)
• Pyrexia (2.6% and 6.9%)
• Anemia (1.5% and 2.7%)
• Infusion-related reactions (0.5% and 3.2%)
• Sepsis (0.5% and 2.1%)
• 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.

Health Canada has approved Jivi^® (antihemophilic factor [recombinant, B-domain deleted, PEGylated]) for use in patients with hemophilia A.

Jivi (formerly BAY94-9027) is a DNA-derived, factor VIII concentrate developed by Bayer.

Health Canada has approved Jivi for use as routine prophylaxis to prevent or reduce the frequency of bleeding episodes in previously treated hemophilia A patients age 12 and older.

Jivi is also approved for the control and prevention of episodic bleeding and for perioperative management of bleeding.

The recommended initial dosing for Jivi as prophylaxis is twice weekly, with the ability to dose every 5 days and further adjust dosing based on bleeding episodes.

Health Canada’s approval of Jivi is based on the PROTECT VIII trial. Results from this trial are available in the U.S. prescribing information for Jivi.

PROTECT VIII enrolled previously treated adults and adolescents (ages 12 to 65) with severe hemophilia A.

In part A, researchers evaluated different dosing regimens for Jivi used as prophylaxis and on-demand treatment. An optional extension study was available to patients who completed part A. In part B, Jivi was used for perioperative management of bleeding.

Efficacy

In part A, there were 132 patients in the intent‐to‐treat population—112 in the prophylaxis group and 20 in the on-demand group.

Patients received Jivi for 36 weeks. For the first 10 weeks, patients in the prophylaxis group received twice-weekly dosing at 25 IU/kg.

Patients with more than one bleed during this time went on to receive 30–40 IU/kg twice weekly. Patients with one or fewer bleeds were eligible for randomization to dosing every 5 days (45–60 IU/kg) or every 7 days (60 IU/kg).

The median annualized bleeding rate (ABR) was 4.1 for the patients who were treated twice weekly and were not eligible for randomization (n=13) and 1.9 for patients who were eligible for randomization but continued on twice-weekly treatment (n=11).

The median ABR was 1.9 for patients who were randomized to treatment every 5 days (n=43) and 0.96 for patients who completed prophylaxis with dosing every 7 days (32/43).

The median ABR for patients treated on demand was 24.1.

There were 388 treated bleeds in the on-demand group and 317 treated bleeds in the prophylaxis group. Overall, 73.3% of responses to treatment were considered “excellent” or “good,” 23.3% were considered “moderate,” and 3.3% were considered “poor.”

There were 17 patients who underwent 20 major surgeries in part B or the extension study and 10 patients who underwent minor surgeries in part A. Jivi provided “good” or “excellent” hemostatic control during all surgeries.

Safety

Safety data are available for 148 patients age 12 and older.

Adverse events in these patients included abdominal pain (3%), nausea (5%), vomiting (3%), injection site reactions (1%), pyrexia (5%), hypersensitivity (2%), dizziness (2%), headache (14%), insomnia (3%), cough (7%), erythema (1%), pruritus (1%), rash (2%), and flushing (1%).

A factor VIII inhibitor was reported in one adult patient, but repeat testing did not confirm the report.

One adult with asthma had a clinical hypersensitivity reaction and a transient increase of IgM anti-PEG antibody titer, which was negative upon retesting.

The cost-effectiveness of tisagenlecleucel (Kymriah) depends on long-term clinical outcomes, which are presently unknown, according to investigators.

If the long-term outcomes are more modest than clinical trials suggest, then payers may be unwilling to cover the costly therapy, reported John K. Lin, MD, of Stanford University, and his colleagues.

Lowering the price or setting up an outcomes-based pricing structure may be necessary to get insurers to cover the therapy.

Tisagenlecleucel is an anti-CD19 chimeric antigen receptor (CAR) T-cell therapy that was approved by the U.S. Food and Drug Administration in August 2017 for relapsed or refractory pediatric B-cell acute lymphoblastic leukemia (ALL).

In 2018, the FDA expanded the indication for tisagenlecleucel to include adults with relapsed or refractory large B-cell lymphoma, though outcomes from lymphoma trials are not analyzed in the current study.

At a wholesale acquisition cost of $475,000 per infusion, it is the most expensive existing oncology therapy to date, and can be accompanied by expensive, potentially fatal adverse effects.

However, clinical trials suggest that tisagenlecleucel can offer years of relapse-free remission, thereby allowing patients to forgo other expensive therapies such as hematopoietic stem cell transplantation (HSCT).

“Although tisagenlecleucel-induced remission rates are promising, compared with those of established therapies (greater than 80% vs. less than 50%), only short-term follow-up data currently exist,” the investigators wrote in the Journal of Clinical Oncology.

“Given the high cost and broad applicability in other malignancies of tisagenlecleucel, a pressing question for policy makers, payers, patients, and clinicians is whether the cost of therapy represents reasonable value.”

The study used a Markov model to assess various long-term clinical outcome rates and cost thresholds of tisagenlecleucel. The lifetime cost of therapy was assessed and compared with costs of existing therapies.

The results showed that a 5-year relapse free survival rate of 40% would make the present cost ($475,000) of tisagenlecleucel economically reasonable. In this scenario, the increased life expectancy would be 12.1 years and would result in an additional 5.07 quality-adjusted life years (QALY) gained at a cost of $61,000 per QALY, compared with blinatumomab.

But if long-term outcomes are less favorable, tisagenlecleucel becomes much less cost effective. A 5-year relapse-free survival rate of 20% would drop increased life expectancy to 3.8 years, resulting in 1.80 QALYs gained and raising the cost to $151,000 per QALY.

“Our results suggest that at tisagenlecleucel’s current price and payment structure, its economic value is uncertain,” the investigators wrote.

They suggested a price drop to $200,000 or $350,000, which would allow the drug to remain cost effective even in a worse-case scenario, in which patients relapse and tisagenlecleucel is a bridge to transplant.

Another option is to move to outcomes-based pricing. Making payment conditional on 7 months of remission would make the treatment cost effective, according to the analysis.

“Price reductions of tisagenlecleucel or payment only for longer-term remissions would favorably influence cost-effectiveness, even if long-term clinical outcomes are modest,” the investigators wrote.

The study was funded by a Veterans Affairs Office of Academic Affiliations advanced fellowship in health service and research development, and a National Center for Advancing Translational Science Clinical and Translational Science Award.

One of the study coauthors reported consulting and research funding from Novartis.

If the long-term outcomes are more modest than clinical trials suggest, then payers may be unwilling to cover the costly therapy, reported John K. Lin, MD, of Stanford University, and his colleagues.

Lowering the price or setting up an outcomes-based pricing structure may be necessary to get insurers to cover the therapy.

Tisagenlecleucel is an anti-CD19 chimeric antigen receptor (CAR) T-cell therapy that was approved by the U.S. Food and Drug Administration in August 2017 for relapsed or refractory pediatric B-cell acute lymphoblastic leukemia (ALL).

In 2018, the FDA expanded the indication for tisagenlecleucel to include adults with relapsed or refractory large B-cell lymphoma, though outcomes from lymphoma trials are not analyzed in the current study.

At a wholesale acquisition cost of $475,000 per infusion, it is the most expensive existing oncology therapy to date, and can be accompanied by expensive, potentially fatal adverse effects.

However, clinical trials suggest that tisagenlecleucel can offer years of relapse-free remission, thereby allowing patients to forgo other expensive therapies such as hematopoietic stem cell transplantation (HSCT).

“Although tisagenlecleucel-induced remission rates are promising, compared with those of established therapies (greater than 80% vs. less than 50%), only short-term follow-up data currently exist,” the investigators wrote in the Journal of Clinical Oncology.

“Given the high cost and broad applicability in other malignancies of tisagenlecleucel, a pressing question for policy makers, payers, patients, and clinicians is whether the cost of therapy represents reasonable value.”

The study used a Markov model to assess various long-term clinical outcome rates and cost thresholds of tisagenlecleucel. The lifetime cost of therapy was assessed and compared with costs of existing therapies.

The results showed that a 5-year relapse free survival rate of 40% would make the present cost ($475,000) of tisagenlecleucel economically reasonable. In this scenario, the increased life expectancy would be 12.1 years and would result in an additional 5.07 quality-adjusted life years (QALY) gained at a cost of $61,000 per QALY, compared with blinatumomab.

But if long-term outcomes are less favorable, tisagenlecleucel becomes much less cost effective. A 5-year relapse-free survival rate of 20% would drop increased life expectancy to 3.8 years, resulting in 1.80 QALYs gained and raising the cost to $151,000 per QALY.

“Our results suggest that at tisagenlecleucel’s current price and payment structure, its economic value is uncertain,” the investigators wrote.

They suggested a price drop to $200,000 or $350,000, which would allow the drug to remain cost effective even in a worse-case scenario, in which patients relapse and tisagenlecleucel is a bridge to transplant.

Another option is to move to outcomes-based pricing. Making payment conditional on 7 months of remission would make the treatment cost effective, according to the analysis.

“Price reductions of tisagenlecleucel or payment only for longer-term remissions would favorably influence cost-effectiveness, even if long-term clinical outcomes are modest,” the investigators wrote.

The study was funded by a Veterans Affairs Office of Academic Affiliations advanced fellowship in health service and research development, and a National Center for Advancing Translational Science Clinical and Translational Science Award.

The U.S. Food and Drug Administration (FDA) has approved carfilzomib (Kyprolis) for a once-weekly dosing option in combination with dexamethasone for patients with relapsed or refractory multiple myeloma (MM).

Carfilzomib administered once-weekly at 70 mg/m² with dexamethasone achieved a superior progression-free survival (PFS) and overall response rates (ORR) compared to twice-weekly carfilzomib at doses of 27 mg/m².

Carfilzomib is not, however, approved for the twice-weekly 27 mg/m² dose with dexamethasone alone, but with dexamethasone and lenalidomide.

The FDA based its approval on data from the phase 3 ARROW trial.

The FDA reviewed and approved the supplemental New Drug Application under its Oncology Center of Excellence Real-Time Oncology Review and Assessment Aid pilot program. The program is exploring a more efficient review process to ensure that safe and effective treatments are available to patients as soon as possible.

The FDA approved the carfilzomib application in just over a month.

ARROW

The ARROW study, reported at the 2018 ASCO annual meeting and published in The Lancet, evaluated 478 patients with relapsed or refractory MM who had received at least two but no more than three prior therapies. Prior therapies could include bortezomib and an immunomodulatory drug.

Patients randomized to the investigational arm receive a 30-minute infusion of once-weekly carfilzomib (20 mg/m² on day 1 of cycle 1; 70 mg/m² on days 8 and 15 of cycle 1; and 70 mg/m² on days 1, 8 and 15 of subsequent cycles) with 40 mg of dexamethasone.

Patients randomized to the comparator arm received a 10-minute infusion of twice-weekly carfilzomib (20 mg/m² on days 1 and 2 of cycle 1; 27 mg/m² on days 8, 9, 15 and 16 of cycle 1; and 27 mg/m² on days 1, 2, 8, 9, 15 and 16 of subsequent cycles) with 40 mg of dexamethasone.

Patients in the once-weekly arm achieved a statistically significant 3.7-month improvement in PFS compared to the twice-weekly regimen. Median PFS was 11.2 months for the once-weekly patients and 7.6 months for the twice-weekly group (P=0.0014).

Patients in the once-weekly group had a 62.9% ORR compared to 40.8% for those treated twice weekly (P<0.0001).

More patients (7.1%) in the once-weekly group had complete responses or better than those in the twice-weekly arm (1.7%).

The safety profile of the two arms were comparable, with no new safety risks identified in the once-weekly arm.

Treatment-emergent adverse events occurring in 20% or more patients in either arm included anemia, diarrhea, fatigue, hypertension, insomnia, and pyrexia.

First approved in 2012, carfilzomib has indications for the following in the U.S.:

• Treatment of patients with relapsed or refractory multiple myeloma who have received one to three lines of therapy in combination with dexamethasone or with lenalidomide plus dexamethasone.
• As a single agent for the treatment of patients with relapsed or refractory multiple myeloma who have received one or more lines of therapy.

The Japanese Ministry of Health, Labour and Welfare has approved blinatumomab (Blincyto®) for the treatment of relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL).

Blinatumomab is the first and only bispecific T-cell engager immunotherapy construct approved globally.

The drug’s approval in Japan is based on data from the phase 3 TOWER study and the phase 1b/2 Horai study.

The TOWER trial (NCT02013167) enrolled 405 patients with Ph-negative, relapsed/refractory B-ALL, 376 of whom ultimately received treatment.

The patients received blinatumomab (n=267) or investigator’s choice of four protocol-defined standard of care (SOC) chemotherapy regimens (n=109):

• FLAG (fludarabine, high-dose cytarabine arabinoside, and granulocyte-colony stimulating factor), with or without an anthracycline (n=49, 45%)
• A high-dose cytarabine arabinoside-based regimen (n=19, 17%)
• A high-dose methotrexate-based regimen (n=22, 20%)
• A clofarabine-based regimen (n=19, 17%).

Blinatumomab demonstrated an improvement in median overall survival over SOC. The median overall survival was 7.7 months with blinatumomab and 4.0 months with SOC (hazard ratio for death=0.71; P=0.012).

Grade 3 or higher adverse events (AEs) of interest, according to the researchers, were:

• Infection (34% with blinatumomab and 52% with chemotherapy)
• Neutropenia (38% and 58%, respectively)
• Elevated liver enzymes (13% and 15%, respectively)
• Neurologic events (9% and 8%, respectively)
• Cytokine release syndrome (5% and 0%, respectively)
• Infusion reactions (3% and 1%, respectively)
• Lymphopenia (2% and 4%, respectively).

Fatal AEs occurred in 19% of patients in the blinatumomab arm and 17% of those in the SOC arm.

These results were published in The New England Journal of Medicine last year.

Horai

For this single-arm trial (NCT02412306), researchers evaluated blinatumomab in 35 Japanese adult and pediatric patients with relapsed or refractory B-ALL. An extension of this study is ongoing.

Efficacy data from Horai are not available.

According to Amgen, the major AEs occurring in adults on this trial were cytokine release syndrome (46.2%), pyrexia (46.2%), decrease in white blood cell count (38.5%), and decrease in platelet count (34.6%).

Major AEs in pediatric patients were elevated liver enzymes (66.7%), pyrexia (66.7%), cytokine release syndrome (55.6%), and abdominal pain (44.4%).

The U.S. Food and Drug Administration (FDA) has approved duvelisib (Copiktra™), a dual PI3K delta/gamma inhibitor, for two indications.

Duvelisib has full FDA approval to treat adults with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) who have received at least two prior therapies.

Duvelisib also has accelerated approval to treat adults with relapsed or refractory follicular lymphoma (FL) who have received at least two prior systemic therapies.

Accelerated approval is based on a surrogate or intermediate endpoint—in this case, overall response rate—that is reasonably likely to predict clinical benefit. Continued approval of duvelisib in FL may be contingent upon results of confirmatory trials verifying that the drug provides a clinical benefit.

Duvelisib will be available in the U.S. immediately, according to Verastem Inc., the company marketing the drug.

Verastem said it will help patients access duvelisib through the Verastem Cares™ program, which is designed to provide information and assistance to patients who are prescribed duvelisib.

The prescribing information for duvelisib includes a boxed warning detailing four fatal and/or serious toxicities associated with the drug—infections, diarrhea or colitis, cutaneous reactions, and pneumonitis.

Verastem said it is implementing an informational risk evaluation and mitigation strategy to provide appropriate dosing and safety information for duvelisib.

The recommended dose of duvelisib is 25 mg orally twice daily, taken continuously in 28-day treatment cycles.

The FDA assessed the new drug application for duvelisib under priority review. The FDA also granted duvelisib fast track designation in CLL and FL as well as orphan drug designation for CLL/SLL and FL.

The FDA’s approval of duvelisib is supported by data from the phase 3 DUO trial and the phase 2 DYNAMO trial. Updated results from both studies are available in the prescribing information for duvelisib.

DUO trial

DUO included 319 patients with CLL (n=312) or SLL (n=7) who had received at least one prior therapy. They were randomized to receive either duvelisib (25 mg orally twice daily) or ofatumumab (initial infusion of 300 mg followed by 7 weekly infusions and 4 monthly infusions of 2000 mg).

The following efficacy results were observed in patients who had received at least two prior therapies, which includes 95 patients in the duvelisib arm and 101 in the ofatumumab arm.

The overall response rate was 78% in the duvelisib arm and 39% in the ofatumumab arm. All responses in both arms were partial responses.

The median progression-free survival was 16.4 months with duvelisib and 9.1 months with ofatumumab (hazard ratio=0.40).

The safety results include all patients treated with duvelisib or ofatumumab.

Twelve percent of patients in the duvelisib arm had fatal adverse events (AEs) within 30 days of the last dose. The same was true of 4% of patients treated with ofatumumab.

Serious AEs occurred in 73% of patients treated with duvelisib. The most common were infection (38%) and diarrhea/colitis (23%).

Thirty-six percent of patients discontinued duvelisib. Most discontinuations were due to diarrhea/ colitis, infection, and rash. Twenty-nine percent of patients in the duvelisib arm required dose reductions, most often due to diarrhea/colitis and rash.

DYNAMO trial

DYNAMO enrolled patients with indolent non-Hodgkin lymphoma whose disease was refractory to both rituximab and chemotherapy or radioimmunotherapy.

There were 83 patients with FL. They had a median of 3 prior anticancer regimens (range, 1-10).

The patients received duvelisib at 25 mg orally twice daily until disease progression or unacceptable toxicity.

The overall response rate was 42%. One patient achieved a complete response, and 34 had a partial response.

Forty-three percent of responders maintained their response at 6 months, and 17% maintained their response at 12 months.

Serious AEs occurred in 58% of FL patients. The most common were diarrhea/colitis, pneumonia, renal insufficiency, rash, and sepsis.

AEs occurring in at least 20% of FL patients included diarrhea/colitis, nausea, fatigue, musculoskeletal pain, rash, neutropenia, cough, anemia, pyrexia, headache, mucositis, abdominal pain, vomiting, transaminase elevation, and thrombocytopenia.

Twenty-nine percent of FL patients discontinued duvelisib, and 23% had dose reductions. Most discontinuations were due to diarrhea/colitis and rash, and most dose reductions were due to transaminase elevation, diarrhea/colitis, lipase increase, and infection.

The overall response rate was 78% in the duvelisib arm and 39% in the ofatumumab arm. All responses in both arms were partial responses.

The median progression-free survival was 16.4 months with duvelisib and 9.1 months with ofatumumab (hazard ratio=0.40).

The safety results include all patients treated with duvelisib or ofatumumab.

Twelve percent of patients in the duvelisib arm had fatal adverse events (AEs) within 30 days of the last dose. The same was true of 4% of patients treated with ofatumumab.

Serious AEs occurred in 73% of patients treated with duvelisib. The most common were infection (38%) and diarrhea/colitis (23%).

Thirty-six percent of patients discontinued duvelisib. Most discontinuations were due to diarrhea/ colitis, infection, and rash. Twenty-nine percent of patients in the duvelisib arm required dose reductions, most often due to diarrhea/colitis and rash.

DYNAMO trial

DYNAMO enrolled patients with indolent non-Hodgkin lymphoma whose disease was refractory to both rituximab and chemotherapy or radioimmunotherapy.

There were 83 patients with FL. They had a median of 3 prior anticancer regimens (range, 1-10).

The patients received duvelisib at 25 mg orally twice daily until disease progression or unacceptable toxicity.

The overall response rate was 42%. One patient achieved a complete response, and 34 had a partial response.

Forty-three percent of responders maintained their response at 6 months, and 17% maintained their response at 12 months.

Serious AEs occurred in 58% of FL patients. The most common were diarrhea/colitis, pneumonia, renal insufficiency, rash, and sepsis.

AEs occurring in at least 20% of FL patients included diarrhea/colitis, nausea, fatigue, musculoskeletal pain, rash, neutropenia, cough, anemia, pyrexia, headache, mucositis, abdominal pain, vomiting, transaminase elevation, and thrombocytopenia.

Twenty-nine percent of FL patients discontinued duvelisib, and 23% had dose reductions. Most discontinuations were due to diarrhea/colitis and rash, and most dose reductions were due to transaminase elevation, diarrhea/colitis, lipase increase, and infection.

Micrograph showing CLL

The U.S. Food and Drug Administration (FDA) has approved duvelisib (Copiktra™), a dual PI3K delta/gamma inhibitor, for two indications.

Duvelisib has full FDA approval to treat adults with relapsed or refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) who have received at least two prior therapies.

Duvelisib also has accelerated approval to treat adults with relapsed or refractory follicular lymphoma (FL) who have received at least two prior systemic therapies.

Accelerated approval is based on a surrogate or intermediate endpoint—in this case, overall response rate—that is reasonably likely to predict clinical benefit. Continued approval of duvelisib in FL may be contingent upon results of confirmatory trials verifying that the drug provides a clinical benefit.

Duvelisib will be available in the U.S. immediately, according to Verastem Inc., the company marketing the drug.

Verastem said it will help patients access duvelisib through the Verastem Cares™ program, which is designed to provide information and assistance to patients who are prescribed duvelisib.

The prescribing information for duvelisib includes a boxed warning detailing four fatal and/or serious toxicities associated with the drug—infections, diarrhea or colitis, cutaneous reactions, and pneumonitis.

Verastem said it is implementing an informational risk evaluation and mitigation strategy to provide appropriate dosing and safety information for duvelisib.

The recommended dose of duvelisib is 25 mg orally twice daily, taken continuously in 28-day treatment cycles.

The FDA assessed the new drug application for duvelisib under priority review. The FDA also granted duvelisib fast track designation in CLL and FL as well as orphan drug designation for CLL/SLL and FL.

The FDA’s approval of duvelisib is supported by data from the phase 3 DUO trial and the phase 2 DYNAMO trial. Updated results from both studies are available in the prescribing information for duvelisib.

The Japanese Ministry of Health, Labour and Welfare (MHLW) has approved the FLT3 inhibitor gilteritinib (Xospata®) to treat patients with FLT3-positive relapsed or refractory acute myeloid leukemia (AML).

Gilteritinib is available in 40 mg tablets. The usual recommended starting dose of gilteritinib for an adult is 120 mg once daily.

The dosage may be adjusted depending on the patient’s condition. However, the daily maximum dose should be 200 mg.

Gilteritinib has demonstrated inhibitory activity against FLT3 internal tandem duplication and FLT tyrosine kinase domain mutation. These two mutations are present in approximately one-third of AML patients.

The MHLW approval of gilteritinib is based on interim results from the phase 3 ADMIRAL study (NCT02421939).

ADIMRAL is designed to compare gilteritinib to salvage chemotherapy in adults who have AML with FLT3 mutations and have relapsed after or are refractory to frontline therapy.

Patients are randomized in a 2:1 ratio to receive gilteritinib (120 mg) or salvage chemotherapy, which may consist of low-dose cytarabine, azacitidine, MEC (mitoxantrone, etoposide, and cytarabine), or FLAG-IDA (fludarabine, cytarabine, and granulocyte colony-stimulating factor [G-CSF] with idarubicin).

Results from this trial have not yet been presented or published. However, a description of the trial was presented at the 2018 ASCO Annual Meeting (abstract TPS7075).

Results from a phase 1/2 study of gilteritinib in AML were published in The Lancet Oncology in 2017.

Orphan and SAKIGAKE designations

The MHLW previously granted SAKIGAKE designation and orphan drug designation to gilteritinib.

To receive orphan designation, a product (drug or medical device) must be intended for use in less than 50,000 patients in Japan. Furthermore, orphan products must be indicated for the treatment of serious diseases for which there are high medical needs.

Companies granted orphan designation can receive preferential tax treatment as well as subsidies through the National Institute of Biomedical Innovation (NIBIO) to reduce the financial burden of product development.

Companies with orphan designation can also receive guidance and consultation from the MHLW, the Pharmaceuticals and Medical Devices Agency (PMDA), and NIBIO on research and development activities.

Orphan designation also allows for priority review and an extension of the re-examination period—up to 10 years for drugs and up to 7 years for medical devices.

SAKIGAKE designation can shorten the review period for a product via prioritized consultation, substantial pre-application consultation, and prioritized review.

SAKIGAKE designation also helps promote development with the review partner system (to be conducted by the PMDA) and “substantial” post-marketing safety measures.

The Japanese Ministry of Health, Labour and Welfare has approved brentuximab vedotin (Adcetris) in combination with doxorubicin, vinblastine, and dacarbazine as a frontline treatment option for CD30-positive Hodgkin lymphoma (HL).

The approval was based on the phase 3 ECHELON-1 trial.

Result from ECHELON-1 were presented at the 2017 ASH Annual Meeting and simultaneously published in The New England Journal of Medicine.

In this trial, researchers compared brentuximab vedotin plus doxorubicin, vinblastine, and dacarbazine (A+AVD) to doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) as frontline treatment for 1334 patients with advanced HL.

The primary endpoint was modified progression-free survival (PFS), which was defined as time to progression, death, or evidence of non-complete response after completion of frontline therapy followed by subsequent anticancer therapy.

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

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

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

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

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

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

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

The Japanese Ministry of Health, Labour and Welfare has approved Jivi® (also known as damoctocog alfa pegol or antihemophilic factor [recombinant] PEGylated-aucl) for the treatment of hemophilia A.

Jivi (formerly BAY94-9027) is a DNA-derived, factor VIII concentrate approved for use in hemophilia A patients age 12 and older.

Jivi is approved for on-demand treatment and control of bleeding episodes, for perioperative management of bleeding, and as routine prophylaxis to reduce the frequency of bleeding episodes.

As prophylaxis, Jivi is typically given twice weekly, but it can also be given every 5 days or once a week, depending on patient needs.

The approval of Jivi in Japan is supported by data from the phase 2/3 PROTECT VIII trial. Some results from this trial were published in the Journal of Thrombosis and Haemostasis in 2016. Additional results are available in the U.S. prescribing information for Jivi.

PROTECT VIII enrolled previously treated adults and adolescents (ages 12 to 65) with severe hemophilia A.

In part A, researchers evaluated different dosing regimens for Jivi used as prophylaxis and on-demand treatment. An optional extension study was available to patients who completed part A.

In part B, researchers evaluated Jivi for perioperative management.

Efficacy

In part A, there were 132 patients in the intent‐to‐treat population—112 in the prophylaxis group and 20 in the on-demand group.

Patients received Jivi for 36 weeks. For the first 10 weeks, patients in the prophylaxis group received twice-weekly dosing at 25 IU/kg.

Patients with more than one bleed during this time went on to receive 30–40 IU/kg twice weekly. Patients with one or fewer bleeds were eligible for randomization to dosing every 5 days (45–60 IU/kg) or every 7 days (60 IU/kg).

The median annualized bleeding rate (ABR) was 4.1 for the patients who were treated twice weekly and were not eligible for randomization (n=13) and 1.9 for patients who were eligible for randomization but continued on twice-weekly treatment (n=11).

The median ABR was 1.9 for patients who were randomized to treatment every 5 days (n=43) and 0.96 for patients who completed prophylaxis with dosing every 7 days (32/43).

The median ABR for patients treated on demand was 24.1.

There were 388 treated bleeds in the on-demand group and 317 treated bleeds in the prophylaxis group. Overall, 73.3% of responses to treatment were considered “excellent” or “good,” 23.3% were considered “moderate,” and 3.3% were considered “poor.”

There were 17 patients who underwent 20 major surgeries in part B or the extension study and 10 patients who underwent minor surgeries in part A. Jivi provided “good” or “excellent” hemostatic control during all surgeries.

Safety

Safety data are available for 148 patients age 12 and older.

Adverse events in these patients included abdominal pain (3%), nausea (5%), vomiting (3%), injection site reactions (1%), pyrexia (5%), hypersensitivity (2%), dizziness (2%), headache (14%), insomnia (3%), cough (7%), erythema (1%), pruritus (1%), rash (2%), and flushing (1%).

A factor VIII inhibitor was reported in one adult patient, but repeat testing did not confirm the report.

One adult with asthma had a clinical hypersensitivity reaction and a transient increase of IgM anti-PEG antibody titer, which was negative upon retesting.
