Roche (SIX: RO, ROG; OTCQX: RHHBY), announced that the Committee for Medicinal Products for Human Use (CHMP) has recommended that Zelboraf be granted full marketing authorization as a monotherapy for the treatment of adult patients with BRAF V600 mutation-positive unresectable or metastatic melanoma. "The CHMP recommendation to approve Zelboraf represents an important milestone for people with metastatic melanoma who until recently had limited treatment options," said Hal Barron, M.D., chief medical officer and head, Global Product Development. "We are working closely with health authorities worldwide to bring Zelboraf to people with this deadly disease as soon as possible."
Metastatic melanoma is the deadliest and most aggressive form of skin cancer with less than one in four people expected to be alive 12 months after their diagnosis(1). Earlier this year, Zelboraf became the first and only US FDA and Swissmedic approved personalised medicine for people with BRAF V600 mutation-positive inoperable or metastatic melanoma that is shown to improve survival. The cobas 4800 BRAF V600 Mutation Test, co-developed by Roche, was approved simultaneously with Zelboraf in the US and CE-marked in the EU where it is commercially available. Zelboraf is designed to target and inhibit mutated forms of the BRAF protein found in about half of all cases of melanoma.
The corresponding European Commission decision on the Marketing Authorization of Zelboraf is expected in February 2012.
Marketing authorization submissions for Zelboraf are currently under review by health authorities in Australia, New Zealand, Brazil, India, Mexico, Canada and other countries worldwide. While Roche seeks regulatory approval of Zelboraf in other countries, a global safety study is providing access to Zelboraf for people with previously treated or untreated BRAF V600 mutation-positive metastatic melanoma.
About Metastatic Melanoma and BRAF
When melanoma is diagnosed early, it is generally a curable disease. However, when it spreads to other parts of the body, it is the deadliest and most aggressive form of skin cancer. A person with metastatic melanoma typically has on average a short life expectancy that is measured in months. In 2008, there were approximately 200,000 new cases worldwide(2) compared with 160,000 in 2002(3). Fewer than one in four people with metastatic melanoma are expected to be alive one year after their diagnosis(4), and every year there are an estimated 40,000 deaths worldwide from the disease(5).
The BRAF protein is a key component of the RAS-RAF pathway involved in normal cell growth and survival. Mutations that keep the BRAF protein in an active state may cause excessive signalling in the pathway, leading to uncontrolled cell growth and survival. These mutations of the BRAF protein are thought to occur in an estimated half of all melanomas and eight percent of solid tumours.
About BRAF V600 Mutation Testing
The cobas 4800 BRAF V600 Mutation Test is a polymerase chain reaction-based diagnostic test developed by Roche. This FDA-approved, CE-marked test was clinically validated in the BRIM2 and BRIM3 studies to identify tumours that carry the BRAF V600E mutation. The test has several advantages compared to Sanger sequencing, a commonly used method, including greater sensitivity and reliability for detecting mutations and quicker results, allowing doctors to know whether a person with metastatic melanoma is eligible for treatment with Zelboraf.
About Zelboraf
Zelboraf is an oral, small molecule, kinase inhibitor indicated for the treatment of patients with inoperable or metastatic melanoma with BRAF V600 mutations. Zelboraf is not recommended for use in melanoma patients with wild-type BRAF. Zelboraf is being co-developed under a 2006 license and collaboration agreement between Roche and Plexxikon, a member of the Daiichi Sankyo Group.
Roche and Genentech are conducting a broad development program with Zelboraf that includes testing combinations with other medicines (both approved and investigational, from Roche/Genentech and other companies), as well as studies in other tumour types. While Roche seeks world-wide approval, Zelboraf is available to eligible patients with BRAF V600 mutation-positive metastatic melanoma through a global safety study. More information about this program or other Zelboraf studies is available at the Roche Clinical Trials Registry at www.roche-trials.com (in the EU) or www.clinicaltrials.gov (in the United States).
