Brief Summary:
Evaluation of the efficacy, safety and biologic effects of neo-adjuvant treatment with vemurafenib + cobimetinib in patients with limited metastasis of melanoma in stage IIIC/IV melanoma.

Condition or disease Intervention/treatment Phase
Malignant Melanoma Drug: vemurafenib + cobimetinib + atezolizumab Phase 2

Detailed Description:
Patients with hardly resectable/unresectable limited metastasis in malignant melanoma stages IIIC/IV (AJCC 2010) carrying the BRAF V600 mutation, in order to achieve operability are enrolled in the NEO-VC-study. The main aim of this study is to achieve operability in a higher percentage of patients by neoadjuvant treatment through shrinkage of the tumors. Patients with operable stage IV disease show an impressive survival benefit with long term (5 y.) survival rates around 30 %. Only a percentage of up to 20 % can presently be treated by complete metastasectomy. This percentage may be enlarged by pre-treatment with an efficacious antitumor drug.
