Onyx Pharmaceuticals and Bayer Healthcare Restructure Global Oncology PartnershipSettlement in Litigation Reached
SAN FRANCISCO, Oct. 12, 2011 -- (Healthcare Sales & Marketing Network) -- Today Onyx Pharmaceuticals, Inc. (Nasdaq:ONXX ) and Bayer HealthCare restructured their partnership for the global development and marketing of Nexavar® (sorafenib) tablets and entered into a new agreement related to regorafenib, a late-stage oncology compound.
Under the terms of the agreements, regorafenib is a Bayer compound, and Bayer will have the final decision-making authority for global development and commercialization. Onyx will receive a royalty on any future global net sales of regorafenib in oncology. In addition, Bayer will contract the Onyx sales force to promote regorafenib, along with Bayer sales representatives, in the United States.
The status of Nexavar under the revised Collaboration Agreement remains largely unchanged. Onyx and Bayer are free to use their respective Nexavar sales forces to promote regorafenib and additional products outside of the collaboration in the future. Bayer will purchase Onyx's royalty rights for sales of the product in Japan in exchange for a one-time payment to Onyx. Bayer will have no obligation to pay Nexavar royalties to Onyx on Japanese sales after December 31, 2011. Further, in the event of a change of control or acquisition of Onyx, the current profit-sharing, co-development and U.S. co-promotion of Nexavar will be preserved.
"These new agreements strengthen the collaboration and provide Onyx the opportunity to participate significantly in the market potential of regorafenib," said N. Anthony Coles, M.D., President and Chief Executive Officer of Onyx Pharmaceuticals. "Together we are taking our collaboration to the next level by more effectively structuring our future working relationship. Onyx and Bayer are committed to benefitting patients worldwide and ensuring that the potential of both Nexavar and regorafenib is fully realized."
"These agreements set the stage for the next chapter in our successful partnership," said Dr. Joerg Reinhardt, Chairman of the Bayer HealthCare Executive Committee. "Innovation is central to Bayer's mission 'Science for a Better Life,' and our ongoing collaboration with Onyx demonstrates the priority we place on working with partners to identify, develop and commercialize new medicines to meet unmet or under-served medical needs."
These agreements also settle and dismiss all claims related to the complaint filed by Onyx against Bayer Corporation and Bayer A.G. in the U.S. District Court (Case No. CV09-2145 MHP).
Regorafenib is an oral multikinase inhibitor of angiogenic, stromal and oncogenic receptor tyrosine kinases (TK) currently being investigated in clinical trials for its potential to treat patients with various tumor types.
Regorafenib 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.
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 breast-feeding 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.
Elevations in serum lipase and reductions in serum phosphate of unknown etiology have been associated with Nexavar. Caution is recommended when administering Nexavar with compounds that are metabolized/eliminated predominantly by the UGT1A9 pathway, UGT1A1 pathway (eg, irinotecan), doxorubicin, docetaxel, fluorouracil, and substrates of CYP2B6 and CYP2C8, and CYP3A4 inducers.
Concomitant use of carboplatin and paclitaxel with sorafenib resulted in an increase in paclitaxel exposure and an increase in Nexavar exposure. Patients taking concomitant warfarin should be monitored regularly for changes in prothrombin time, INR, or clinical bleeding episodes. 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.
