About the Kyprolis™ (proposed trademark for carfilzomib) Development Program
Kyprolis is an investigational agent and is not approved by the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA) or other health authorities.
A new drug application (NDA) for Kyprolis for the treatment of patients with relapsed and refractory multiple myeloma who have received at least two prior therapies is currently being reviewed by the U.S. FDA, and the anticipated date for completion of review is July 27, 2012. The NDA submission is based on the Kyprolis 003-A1 study, an open-label, single-arm Phase 2b trial, as well as safety data from additional studies.
Kyprolis is being studied in several clinical trials either as a single-agent or in combination with other therapies, including:
- A Phase 3 clinical trial, known as the ASPIRE trial, has completed enrollment and is evaluating the combination of lenalidomide and low-dose dexamethasone with or without Kyprolis in patients with relapsed multiple myeloma who have received one to three prior therapies. The company has an agreement with the FDA on a Special Protocol Assessment (SPA) and has received Scientific Advice from the European Medicines Agency (EMA) on the design and planned analysis of the trial.
- A Phase 3 clinical trial, called the FOCUS trial, is evaluating single-agent Kyprolis in patients with relapsed and refractory myeloma who have received three or more prior therapies. The trial is designed to facilitate regulatory approvals around the world.
- A Phase 3 clinical trial, called ENDEAVOR, is planned to begin enrolling patients in mid-2012. The head-to-head trial will evaluate the combination of Kyprolis and low-dose dexamethasone vs. the combination of bortezomib and low-dose dexamethasone.
- A Phase 1/2 study being conducted by Onyx's partner Ono Pharmaceutical Co., Ltd is evaluating Kyprolis in Japanese patients with relapsed/refractory multiple myeloma.
About Nexavar (sorafenib) tablets
Nexavar is approved in the U.S. for the treatment of patients with unresectable liver cancer and for the treatment of patients with advanced kidney cancer. Nexavar inhibits both the tumor cell and tumor vasculature. In preclinical studies, Nexavar has been shown to inhibit members of two classes of kinases thought to be involved in both cell proliferation (growth) and angiogenesis (blood supply) – two important processes that enable cancer growth. These kinases included Raf kinase, VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-B, KIT, FLT-3 and RET.
Nexavar is currently approved in more than 100 countries.
Nexavar is also being evaluated by the companies, international study groups, government agencies and individual investigators.
Important Safety Considerations for Patients Taking Nexavar
Nexavar in combination with carboplatin and paclitaxel is contraindicated in patients with squamous cell lung cancer. Nexavar may cause fetal harm when administered to a pregnant woman. Women of childbearing potential are advised to avoid becoming pregnant and female patients should also be advised against breastfeeding while receiving Nexavar.
Cardiac ischemia and/or myocardial infarction may occur. Temporary or permanent discontinuation of Nexavar should be considered in patients who develop cardiac ischemia and/or myocardial infarction. Gastrointestinal perforation was an uncommon adverse reaction and has been reported in less than 1% of patients taking Nexavar.
Uncommon but serious adverse reactions, including keratoacanthomas/squamous cell cancer of the skin and Stevens-Johnson Syndrome, have been reported in clinical trials.
An increased risk of bleeding may occur following Nexavar administration. If bleeding necessitates medical intervention, consider discontinuation of Nexavar. Hypertension may occur early in the course of treatment. Monitor blood pressure weekly during the first 6 weeks and periodically thereafter and treat, as required.
Hand-foot skin reaction and rash are common and management may include topical therapies for symptomatic relief. In cases of any severe or persistent adverse reactions, temporary treatment interruption, dose modification, or permanent discontinuation of Nexavar should be considered. Temporary interruption of Nexavar therapy is recommended in patients undergoing major surgical procedures. Nexavar can prolong the QT/QTc interval and increase the risk for ventricular arrhythmias. Avoid use in patients with congenital long QT syndrome and monitor patients with congestive heart failure, bradyarrhythmias, drugs known to prolong the QT interval, and electrolyte abnormalities.
Elevations in serum lipase and reductions in serum phosphate of unknown etiology have been associated with Nexavar. Monitor patients taking concomitant warfarin regularly for changes in prothrombin time, INR, or clinical bleeding episodes. Avoid concomitant use of strong CYP3A4 inducers, when possible, because inducers can decrease the systemic exposure of sorafenib. Nexavar exposure decreases when co-administered with oral neomycin. Effects of other antibiotics on Nexavar pharmacokinetics have not been studied.
Most common adverse reactions reported for Nexavar-treated patients vs placebo-treated patients in unresectable HCC, respectively, were: diarrhea (55% vs 25%), fatigue (46% vs 45%), abdominal pain (31% vs 26%), weight loss (30% vs 10%), anorexia (29% vs 18%), nausea (24% vs 20%), and hand-foot skin reaction (21% vs 3%). Grade 3/4 adverse reactions were 45% vs 32%.
Most common adverse reactions reported for Nexavar-treated patients vs placebo-treated patients in advanced RCC, respectively, were: diarrhea (43% vs 13%), rash/desquamation (40% vs 16%), fatigue (37% vs 28%), hand-foot skin reaction (30% vs 7%), alopecia (27% vs 3%),and nausea (23% vs 19%). Grade 3/4 adverse reactions were 38% vs 28%. During postapproval use of Nexavar, the following adverse drug reactions have been identified: angioedema and drug-induced hepatitis, including reports of hepatic failure and death.
