FDA Sets PDUFA Target Action Date of April 30, 2018
THOUSAND OAKS, CA, USA I August 30, 2017 I Amgen (NASDAQ:AMGN) today announced that the U.S. Food and Drug Administration (FDA) has accepted for review a supplemental New Drug Application (sNDA) based on the overall survival (OS) data from the Phase 3 head-to-head ENDEAVOR trial demonstrating that KYPROLIS® (carfilzomib) and dexamethasone (Kd) reduced the risk of death by 21 percent and increased OS by 7.6 months versus Velcade® (bortezomib) and dexamethasone (Vd) in patients with relapsed or refractory multiple myeloma (median OS 47.6 months for Kd versus 40.0 months for Vd, HR=0.79; p=0.01). The FDA has set a Prescription Drug User Fee Act (PDUFA) action date of April 30, 2018.
"Effective proteasome inhibition is an essential approach to treating multiple myeloma. Patients in the ENDEAVOR study receiving KYPROLIS and dexamethasone lived 7.6 months longer than those on Velcade and dexamethasone," said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen. "These data, along with compelling overall survival results from the Phase 3 ASPIRE trial, clearly demonstrate that KYPROLIS-based regimens should be considered new standards of care for appropriate patients with relapsed multiple myeloma."
If approved by the FDA, the KYPROLIS U.S. prescribing information will include this data from the ENDEAVOR trial showing that KYPROLIS, administered at the 56 mg/m2 dose as a 30-minute infusion twice weekly with dexamethasone, helped relapsed or refractory multiple myeloma patients live longer than patients administered Vd. Full results from the ENDEAVOR OS analysis were recently published online in The Lancet Oncology.
Adverse events observed in this updated analysis were consistent with those previously reported for ENDEAVOR. The most common adverse events (greater than or equal to 20 percent) in the KYPROLIS arm were anemia, diarrhea, pyrexia, dyspnea, fatigue, hypertension, cough, insomnia, upper respiratory tract infection, peripheral edema, nausea, bronchitis, asthenia, back pain, thrombocytopenia and headache.
Since its approval in 2012, more than 50,000 patients worldwide have received KYPROLIS. The KYPROLIS clinical program continues to focus on providing solutions for physicians and patients in treating this frequently relapsing and difficult-to-treat cancer. KYPROLIS is available for patients whose myeloma has relapsed or become resistant to another treatment and continues to be studied in a range of combinations and patient populations.
The randomized ENDEAVOR (RandomizEd, OpeN Label, Phase 3 Study of Carfilzomib Plus DExamethAsone Vs Bortezomib Plus DexamethasOne in Patients With Relapsed Multiple Myeloma) trial of 929 patients evaluated Kd versus Vd in patients whose multiple myeloma has relapsed after at least one, but not more than three, prior therapeutic regimens. The primary endpoint of the trial was progression free survival, defined as the time from treatment initiation to disease progression or death. The primary analysis was published in The Lancet Oncology and is described in the Prescribing Information.
Patients received treatment until progression with KYPROLIS as a 30-minute infusion on days 1, 2, 8, 9, 15 and 16 of 28 day treatment cycles, along with low-dose dexamethasone (20 mg). For Cycle 1 only, KYPROLIS was administered at 20 mg/m2 on days 1 and 2, and if tolerated was escalated to 56 mg/m2 from day 8 of Cycle 1 onwards. Patients who received bortezomib (1.3 mg/m2) with low-dose dexamethasone (20 mg) were treated with bortezomib administered subcutaneously or intravenously at the discretion of the investigator and in accordance with regional regulatory approval of bortezomib. More than 75 percent of the patients in the control arm received bortezomib subcutaneously. Patients were enrolled from 198 sites in 27 countries.

About Multiple Myeloma
Multiple myeloma is an incurable blood cancer, characterized by a recurring pattern of remission and relapse.1 It is a rare and very aggressive disease that accounts for approximately one percent of all cancers.2,3 In the U.S., there are nearly 95,000 people living with, or in remission from, multiple myeloma.4 Approximately 30,330 Americans are diagnosed with multiple myeloma each year and 12,650 patient deaths are reported on an annual basis.4
About KYPROLIS® (carfilzomib)
Proteasomes play an important role in cell function and growth by breaking down proteins that are damaged or no longer needed.5 KYPROLIS has been shown to block proteasomes, leading to an excessive build-up of proteins within cells.5 In some cells, KYPROLIS can cause cell death, especially in myeloma cells because they are more likely to contain a higher amount of abnormal proteins.5,6
KYPROLIS is approved in the U.S. for the following:
- In combination with dexamethasone or with lenalidomide plus dexamethasone for the treatment of patients with relapsed or refractory multiple myeloma who have received one to three lines of therapy.
- As a single agent for the treatment of patients with relapsed or refractory multiple myeloma who have received one or more lines of therapy.
KYPROLIS is also approved in Argentina, Australia, Bahrain, Canada, Hong Kong, Israel, Japan, Kuwait, Lebanon, Macao, Mexico, Thailand, Colombia, S. Korea, Canada, Qatar, Switzerland, United Arab Emirates, Turkey, Russia, Brazil, India, Oman and the European Union. Additional regulatory applications for KYPROLIS are underway and have been submitted to health authorities worldwide.
