Quick FDA approval for brentuximab vedotin in PTCL
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).

FDA approves generic drugs for APL
The U.S. Food and Drug Administration (FDA) has now approved three generic arsenic trioxide products for use in patients with acute promyelocytic leukemia (APL).
Two of the products—from Zydus Cadila and Amring Pharmaceuticals—were approved on November 13.
The third—from Fresenius Kabi—was approved in August and launched in the United States last month.
All three injectable arsenic trioxide products (1 mg/mL) are generic versions of Teva’s Trisenox.
Since 2000, Trisenox has been FDA-approved to induce remission and as consolidation therapy for patients with APL who are refractory to, or have relapsed after, retinoid and anthracycline chemotherapy, and whose APL is characterized by presence of the t(15;17) translocation or PML/RAR-alpha gene expression.
In January, the FDA approved Trisenox for use in combination with tretinoin to treat adults with newly diagnosed, low-risk APL with the t(15;17) translocation or PML/RAR-alpha gene expression.

FDA approves elotuzumab combo for rel/ref MM
The U.S. Food and Drug Administration (FDA) has approved elotuzumab (Empliciti®) in combination with pomalidomide and dexamethasone.
The combination is now approved for use in adults with multiple myeloma (MM) who have received at least two prior therapies, including lenalidomide and a proteasome inhibitor.
Elotuzumab is also FDA-approved in combination with lenalidomide and dexamethasone to treat adult MM patients who have received one to three prior therapies.
The FDA’s latest approval of elotuzumab is based on results from the phase 2 ELOQUENT-3 trial, which were presented at the 23rd Congress of the European Hematology Association in June.
ELOQUENT-3 enrolled MM patients who had refractory or relapsed and refractory MM and had received both lenalidomide and a proteasome inhibitor.
The patients were randomized to receive elotuzumab plus pomalidomide and dexamethasone (EPd, n=60) or pomalidomide and dexamethasone (Pd, n=57) in 28-day cycles until disease progression or unacceptable toxicity.
The overall response rate was 53.3% in the EPd arm and 26.3% in the Pd arm (P=0.0029). The rate of complete response or stringent complete response was 8.3% in the EPd arm and 1.8% in the Pd arm.
The median progression-free survival was 10.25 months with EPd and 4.67 months with Pd (hazard ratio=0.54, P=0.0078).
Serious adverse events (AEs) occurred in 22% of patients in the EPd arm and 15% in the Pd arm. The most frequent serious AEs (in the EPd and Pd arms, respectively) were pneumonia (13% and 11%) and respiratory tract infection (7% and 3.6%).
AEs occurring in at least 10% of patients in the EPd arm and at least 5% of those in the Pd arm (respectively) included:
- Constipation (22% and 11%)
- Hyperglycemia (20% and 15%)
- Pneumonia (18% and 13%)
- Diarrhea (18% and 9%)
- Respiratory tract infection (17% and 9%)

FDA and EC approve pegfilgrastim biosimilar
The U.S. Food and Drug Administration (FDA) and European Commission (EC) have approved Coherus BioSciences, Inc.’s pegfilgrastim-cbqv (Udenyca™), a biosimilar of Amgen’s pegfilgrastim product (Neulasta).
Both agencies approved pegfilgrastim-cbqv (formerly CHS-1701) for cancer patients receiving myelosuppressive chemotherapy.
Pegfilgrastim-cbqv is FDA-approved “to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anticancer drugs associated with a clinically significant incidence of febrile neutropenia.”
The product is EC-approved to reduce “the duration of neutropenia and the incidence of febrile neutropenia in adult patients treated with cytotoxic chemotherapy for malignancy (with the exception of chronic myeloid leukemia and myelodysplastic syndromes).”
The U.S. prescribing information for pegfilgrastim-cbqv is available at www.UDENYCA.com, and the European summary of product characteristics is available on the European Medicines Agency’s website.
The FDA and EC approvals of pegfilgrastim-cbqv were supported by analyses establishing biosimilarity as well as pharmacokinetic, pharmacodynamic, and immunogenicity studies of healthy subjects (NCT02650973, NCT02385851, and NCT02418104).
Results from one of these studies (NCT02650973) were presented at the 2017 ASCO Annual Meeting.
“Udenyca’s robust clinical package includes a dedicated immunogenicity similarity study in over 300 healthy subjects,” said Barbara Finck, MD, chief medical officer of Coherus BioSciences.
“In support of that study, and as part of our commitment to ensuring patient safety, we deployed a battery of sensitive immunogenicity assays. This effort not only supported the biosimilarity of Udenyca but also advanced the understanding of the immunogenic response of pegfilgrastim products.”

Health Canada approves pralatrexate for rel/ref PTCL
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 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.

Canada approves Jivi for hemophilia A
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.

Weighing the costs of CAR T-cell therapy
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.

Carfilzomib receives approval for once-weekly dosing
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 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.

Blinatumomab approved to treat ALL in Japan
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%).
