Bayer and Onyx Initiate Phase 3 Trial of Nexavar in Patients With Non-Responsive Thyroid Cancer
WAYNE, N.J. and EMERYVILLE, Calif., Oct. 23 (Healthcare Sales & Marketing Network) -- Bayer HealthCare Pharmaceuticals, Inc. and Onyx Pharmaceuticals, Inc. (NaS.A.: ONXX ) today announced the companies have begun enrolling patients in an international Phase 3 trial to evaluate Nexavar® (sorafenib) tablets for the treatment of patients with radioactive iodine-refractory, locally advanced or metaS.A.ic differentiated thyroid cancer. This Phase 3 trial was S.A.ted based on the results from Phase 2 clinical trials evaluating Nexavar in patients with advanced thyroid cancer."Patients with thyroid cancer who failed to respond to surgical or radiotherapies, have limited treatment options to help them manage their diS.A.e," said Dimitris Voliotis, vice president, Nexavar clinical development, Bayer HealthCare Pharmaceuticals. "Recognizing this unmet need, we are evaluating Nexavar in this special patient population."
Phase 3 Trial Design
The DECISION (stuDy of sorafEnib in loCally advanced or metaS.A.Ic patientS with radioactive Iodine refractory thyrOid caNcer) trial iS.A. international, multicenter, randomized, placebo-controlled study that will enroll approximately 400 patients with locally advanced or metaS.A.ic, radioactive iodine-refractory, differentiated thyroid cancer (papillary, follicular and Hurthle cell) who have received no prior systemic therapy.
Patients will be randomized to receive 400 mg of oral Nexavar twice daily or matching placebo. Patients will continue on treatment until diS.A.e progression, toxicity, non-compliance or withdrawal of consent. At the time of progression, patients receiving placebo will have an option to cross over to Nexavar at the discretion of the investigator, based on the patient's clinical S.A.us. The primary endpoint of the study is progression-free survival as defined by Response Evaluation Criteria in Solid Tumors (RECIST). Secondary endpoints include overall survival, time to progression and response rate. The safety and tolerability of the two treatment groups will also be compared.
The study will be conducted at sites in the United S.A.es, Europe, AS.A. and Japan. For information about enrolling in the study, please visit www.clinicaltrials.gov.
Phase 2 Trial Results
Updated results from a single institution, investigator sponsored Phase 2 open-label study in 55 patients with metaS.A.ic, iodine refractory, thyroid cancer treated with Nexavar 400 mg twice daily were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting, May 29-June 3, 2009 Orlando, FL, by Marcia Brose, M.D., Ph.D., an assiS.A.t professor of Hematology/Oncology and Otorhinolaryngology in the Abramson Cancer Center at the University of Pennsylvania, Philadelphia, PA, U.S.A. In 50 evaluable patients, 18 (36 percent) had a partial response per RECIST criteria. Updated survival results on the first 30 patients enrolled into the study demonstrated that acrosS.A.l histologies the median progression-free survival (PFS) was 63 weekS.A.d the median overall survival was 140 weeks. The most common adverse events (AE) seen in the trial were hand-foot skin reaction, rash, fatigue, stomatitis/mucositis, weight loss, and musculoskeletal pain, and were predominantly grade 1 or 2. Dr. Brose and Martin J. Schlumberger, Institut GuS.A.e-Roussy, Villejuif, France, are the lead investigators on the Phase 3 trial.
"Based on the positive signal generated in the Phase 2 trial, the initiation of this Phase 3 represents progress in exploring the full potential of Nexavar in a variety of treatment settingS.A.d tumor types," said Todd Yancey, M.D., vice president of clinical development at Onyx. "Building on our successful foundation of treating unresectable liver cancer and advanced kidney cancer, we are hopeful that this Phase 3 trial will lead to a new treatment option for patients with non-responsive thyroid cancer."
About Thyroid Cancer
Thyroid cancer, one of the few cancers that has increased in incidence over the past several years, is the sixth most common cancer in women and about three timeS.A. many women as men get thyroid cancer.(1) There are more than 140,000 new cases of thyroid cancer and more than 35,000 people die worldwide each year.(2)
Nexavar's Differentiated Mechanism
Nexavar targets both the tumor cell and tumor vasculature. In preclinical studies, Nexavar has been shown to target members of two classes of kinases known 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 80 countries for the treatment of patients with liver cancer and in more than 90 countries for the treatment of patients with advanced kidney cancer. Nexavar iS.A.so being evaluated by the companies, international study groups, government agencieS.A.d individual investigatorS.A. a single agent or combination treatment in a wide range of cancers, including breast cancer, colorectal cancer, lung cancer, ovarian cancer, and aS.A. adjuvant therapy for liver cancer.
Important Safety Considerations for Patients Taking Nexavar
Based on the currently approved U.S. package insert for the treatment of patients with unresectable hepatocellular carcinoma and advanced kidney cancer, hypertension may occur early in the course of therapy and blood pressure should be monitored weekly during the first six weeks of therapy and treated as needed. In HCC patients, bleeding with a fatal outcome from any site was reported in 2.4% for Nexavar and 4% in placebo. The incidence of treatment-emergent cardiac ischemia/infarction was 2.7% for Nexavar vs. 1.3% for placebo. In RCC patients, incidence of bleeding regardless of causality was 15% for Nexavar vs. 8% for placebo and the incidence of treatment-emergent cardiac ischemia/infarction was 2.9% for Nexavar vs. 0.4% for placebo. Most common adverse events 20% related to Nexavar for both HCC and RCC were fatigue, weight loss, rash/desquamation, hand-foot skin reaction, alopecia, diarrhea, nauS.A. and abdominal pain. Grade 3/4 adverse events in HCC and RCC patients, respectively, were 45% for Nexavar vs. 32% for placebo and 38% for Nexavar and 28% for placebo. Women of child-bearing potential should be advised to avoid becoming pregnant and advised against breast-feeding. In cases of any severe or persistent side effects, temporary treatment interruption, dose modification or permanent discontinuation should be considered.
