FDA approves Roche’s Tecentriq plus Cotellic and Zelboraf for people with advanced melanoma - Seite 2

Five hundred and fourteen adult patients took part in the study. Randomisation was stratified by lactate dehydrogenase (LDH) level and geographic region. Eligible patients were randomised 1:1 to one of two treatment groups, to receive 28-day cycles of either: Tecentriq plus Cotellic and Zelboraf (the Tecentriq group) or Placebo plus Cotellic and Zelboraf (the control group). In cycle 1, all patients received once-daily oral Cotellic 60 mg plus twice-daily oral Zelboraf 960 mg for 21 days followed by twice-daily Zelboraf 720 mg or 960 mg for 7 days in the Tecentriq group or control group, respectively. Patients in the Tecentriq group received Zelboraf 720 mg Days 1–28 of each subsequent cycle. The lower 720 mg dose of Zelboraf in the Tecentriq group was a safety measure to mitigate the risk of overlapping toxicities, while ensuring an efficacious dose of Zelboraf. Treatment was continued until investigator-determined disease progression, unacceptable toxicity, death, patient or physician decision to withdraw, whichever occurred first.

About advanced melanoma
Melanoma is a less common, but more aggressive and potentially deadly form of skin cancer.^1,2 When melanoma is diagnosed early, it is generally a curable disease,^3,4 but most people with advanced melanoma have a poor prognosis.² More than 287,000 people worldwide are currently diagnosed with melanoma each year.⁵ BRAF is mutated in approximately half of melanomas.⁶ In recent years, there have been significant advances in treatment for advanced melanoma and people with the disease have more options. However, it continues to be a serious health issue with a high medical need and a steadily increasing incidence over the past 30 years.⁷

About Tecentriq (atezolizumab)
Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

About Cotellic (cobimetinib)
Cotellic is designed to inhibit MEK1/2, proteins in a cell signaling pathway that helps control cell growth and survival. Cotellic, when used in combination with Zelboraf, is approved in the United States and Europe, as well as many countries around the world, for the treatment of people with melanoma that has spread to other parts of the body or cannot be removed by surgery and has a BRAF V600 mutation. Cotellic was discovered by Exelixis and is being developed by Genentech, a member of the Roche Group, in collaboration with Exelixis.
