"In the first ever comparative Phase 3 head-to-head study of two proteasome inhibitors in relapsed multiple myeloma, Kyprolis in combination with dexamethasone nearly doubled progression-free survival compared to a current standard of care regimen," said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen.
"We are pleased that the CHMP has recognized these robust data with a positive opinion, and we look forward to ensuring approval of this extended indication of Kyprolis."
The CHMP positive opinion is based on data from the Phase 3 head-to-head ENDEAVOR study in which patients with multiple myeloma treated with Kyprolis plus dexamethasone achieved superior progression-free survival (PFS) of 18.7 months compared to 9.4 months in those receiving Velcade (bortezomib) plus dexamethasone, (HR=0.53; 95 percent CI: 0.44,0.65 p<0.0001).
The most common adverse reactions that occurred in greater than 20 percent of patients in the Kyprolis arm were anemia, fatigue, diarrhea, thrombocytopenia, nausea, pyrexia, dyspnea, respiratory tract infection, cough and peripheral edema.
The CHMP positive opinion will now be reviewed by the European Commission (EC) and if granted, the marketing authorization will be extended to include Kyprolis in combination with dexamethasone in the 28 member countries of the European Union, as well as Iceland, Lichtenstein and Norway.
The extended indication adopted by the CHMP is: Kyprolis in combination with either lenalidomide and dexamethasone or dexamethasone alone is indicated for the treatment of adult patients with multiple myeloma who have received at least one prior therapy.
The EC previously granted marketing authorization for Kyprolis in combination with lenalidomide and dexamethasone for the treatment of adult patients with multiple myeloma who have received at least one prior therapy based on results of the ASPIRE study in November 2015. Today’s CHMP positive opinion follows the U.S. Food and Drug Administration’s approval of a supplemental New Drug Application based on the ENDEAVOR results in January 2016.
About Multiple Myeloma
Multiple myeloma is characterized by a recurring pattern of remission and relapse. It is a rare and very aggressive orphan disease that accounts for approximately one percent of all cancers worldwide. In Europe, approximately 39,000 patients are diagnosed with multiple myeloma each year and 24,000 patient deaths are reported on an annual basis.
About ENDEAVOR
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 Kyprolis in combination with low-dose dexamethasone, versus bortezomib with low-dose dexamethasone 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 PFS, defined as the time from treatment initiation to disease progression or death. In a clinical trial, measuring the PFS is one way to demonstrate how well a treatment works.6
This study was conducted at 235 sites worldwide. For information about this trial, please visit www.clinicaltrials.gov under trial identification number NCT01568866.
About Kyprolis (carfilzomib)
Proteasomes play an important role in cell function and growth by breaking down proteins that are damaged or no longer needed.7 Kyprolis has been shown to block proteasomes, leading to an excessive build-up of proteins within cells.7 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.7,8
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, Israel, Kuwait, Mexico, Thailand, Colombia, Korea, Canada, Switzerland, Russia and the European Union. Additional regulatory applications for Kyprolis are underway and have been submitted to health authorities worldwide.
