Nexavar® (sorafenib tablets) now Approved in Canada for the Treatment of Differentiated Thyroid Cancer
- Nexavar is the only approved treatment for patients with RAI-refractory differentiated thyroid cancer
- Nexavar significantly extended progression-free survival in patients with RAI-refractory differentiated thyroid cancer compared to placebo in the Phase III DECISION trial
TORONTO, July 7, 2014 /CNW/ - Bayer Inc. is pleased to announce the Health Canada approval of Nexavar for the treatment of patients with locally advanced or metastatic, progressive, differentiated thyroid carcinoma (DTC), refractory to radioactive iodine (RAI).
The approval is based on data from the Phase III DECISION (stuDy of sorafEnib in loCally advanced or metastatIc patientS with radioactive Iodine refractory thyrOid caNcer) trial. In the trial, sorafenib significantly extended progression-free survival (PFS), the primary endpoint of the study, compared to placebo (HR=0.59 [95% CI, 0.45-0.76]; p<0.0001), which represents a 41 percent reduction in the risk of disease progression or death for patients who received sorafenib compared to placebo-treated patients. The median PFS was 10.8 months in patients treated with sorafenib, compared to 5.8 months in patients receiving placebo.
The safety and tolerability profile of sorafenib in patients in the trial was generally consistent with the known profile of sorafenib. The most common treatment-emergent adverse events in the sorafenib arm were hand-foot skin reaction, diarrhea, alopecia, weight loss, fatigue, hypertension and rash. Results from the trial were presented at the Annual Meeting of the American Society of Clinical Oncology (ASCO) in June 2013 and published in The Lancet in April 2014.
About Thyroid Cancer
Thyroid cancer is the most common endocrine malignancy1. There are more than 298,000 new cases of thyroid cancer annually and nearly 40,000 people die from thyroid cancer worldwide each year.2 In 2014, it is estimated that 6,000 Canadians will be diagnosed with thyroid cancer.3
Papillary, follicular (including Hürthle cell) and poorly differentiated types of thyroid cancer are classified as "differentiated thyroid cancer" and account for approximately 94 percent of all thyroid cancers.4 While the majority of differentiated thyroid cancers are treatable, RAI-refractory locally advanced or metastatic disease is more difficult to treat and is associated with a lower patient survival rate.
About Nexavar® (sorafenib tablets)
Nexavar® (sorafenib tablets), an oral anti-cancer therapy, is currently approved in more than 100 countries worldwide. In Canada, it is approved for the treatment of hepatocellular carcinoma (HCC) and for the treatment of patients with advanced renal cell carcinoma (RCC) who have failed or are intolerant to prior systemic therapy5. Nexavar is also now approved in Canada for the treatment of patients with locally advanced or metastatic, progressive differentiated (papillary/follicular/Hürthle cell) thyroid carcinoma (DTC), refractory to radioactive iodine (RAI).
In preclinical studies, Nexavar has been shown to inhibit multiple kinases thought to be involved in both cell proliferation (growth) and angiogenesis (blood supply) - two important processes that enable cancer growth. These kinases include Raf kinase (C-CRAF, BRAF, mutant BRAF), VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-B, KIT, FLT-3, RET-DTC and RET.
Nexavar is also being evaluated by Bayer and Onyx, international study groups, government agencies and individual investigators in a range of other cancers.
Nexavar is co-developed by Onyx Pharmaceuticals, Inc., an Amgen subsidiary, and Bayer, except in Japan where Bayer manages all development. The companies co-promote Nexavar in the U.S. Outside of the U.S. Bayer has exclusive marketing rights, and Bayer and Onyx share profits globally, excluding Japan.
