Nexavar is the only treatment approved in Europe and the United States for patients with this type of thyroid cancer / Nexavar significantly extended progression-free survival compared to placebo in Phase III DECISION trial
May 30, 2014
Bayer HealthCare and Onyx Pharmaceuticals, Inc., an Amgen subsidiary, announced today that the European Commission (EC) has granted marketing authorization for the oral multi-kinase inhibitor Nexavar® (sorafenib) for the treatment of patients with progressive, locally advanced or metastatic, differentiated (papillary/follicular/Hürthle cell) thyroid carcinoma (DTC), refractory to radioactive iodine (RAI). Nexavar was previously granted orphan drug designations for the treatment of follicular and papillary thyroid cancer in the EU.
“Differentiated thyroid cancer is a rare but serious disease, with patients who were lacking new treatment options for over forty years,” said Dr. Joerg Moeller, Member of the Bayer HealthCare Executive Committee and Head of Global Development. “The approval in DTC marks Nexavar’s third indication in Europe, and we are proud to extend this proven treatment option to even more people in need.”
The approval is based on data from the Phase III DECISION (stuDy of sorafEnib in loCally advanced or metastatIc patientS with radioactiveIodine 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, 0.46-0.76]; p<0.001), 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.
DECISION Trial Design
DECISION was an international, multicenter, placebo-controlled study. A total of 417 patients with locally advanced or metastatic, progressive, RAI-refractory, differentiated thyroid cancer (papillary, follicular, Hürthle cell and poorly differentiated) who had received no prior chemotherapy, tyrosine kinase inhibitors, monoclonal antibodies that target VEGF or VEGF receptor, or other targeted agents for thyroid cancer were randomized to receive 400 mg of oral sorafenib twice daily (207 patients) or matching placebo (210 patients). Ninety-six percent of randomized patients had metastatic disease.
About Thyroid Cancer
Thyroid cancer is the most common endocrine malignancy. There are more than 298,000 new cases of thyroid cancer annually and nearly 40,000 people die from thyroid cancer worldwide each year.
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. 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)
Nexavar® (sorafenib), an oral anti-cancer therapy, is currently approved in more than 100 countries worldwide. In Europe, 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 prior interferon-alpha or interleukin-2 based therapy or are considered unsuitable for such therapy. Nexavar is also now approved in Europe for progressive, locally advanced or metastatic, differentiated (papillary/follicular/Hürthle cell) thyroid carcinoma, refractory to radioactive iodine. In the U.S., Nexavar is also approved for the treatment of patients with locally recurrent or metastatic, progressive, differentiated thyroid cancer (DTC) that is refractory to radioactive iodine treatment.
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, VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-B, KIT, FLT-3 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.
