Title: Neoadjuvant Treatment With the Combination of Vemurafenib, Cobimetinib and Atezolizumab in Limited Metastasis of Malignant Melanoma (AJCC Stage IIIC/IV) and Integrated Biomarker Study: a Single Armed, Two Cohort, Phase II EADO Trial NEO-VC
Brief Summary: Evaluation of the efficacy, safety and biologic effects of neo-adjuvant treatment with vemurafenib + cobimetinib + atezolizumab in patients with limited metastasis of melanoma in stage IIIC/IV melanoma.


Options:
A: Inclusion Criteria:

* ≥18 years of age
* Written informed consent.
* Histologically confirmed, resectable American Joint Committee on Cancer (AJCC, 8th edition) stage IIIB, IIIC (Tx, T0, T1-4, N1b, N2b, N3b, M0) cutaneous melanoma or unknown primary melanoma with sufficient cutaneous and/or nodal disease to enable multiple excisional or core biopsies (at baseline, week 1 and week 2). 'Resectable' tumours are defined as having no significant vascular, central nervous system or bony involvement. Only cases where a complete surgical resection with tumour-free margins can safely be achieved are defined as resectable. Patients who may not have sufficient disease to enable multiple biopsies at weeks 1 and 2 will not be excluded, however the intention of the study is that at least one biopsy at these time points is required.
* Measurable disease according to RECIST version 1.1 criteria (≥ 10mm longest diameter for non-nodal lesions and / or ≥ 15mm in shortest diameter for lymph nodes) within 4 weeks of randomisation. 'Measurable' disease may be ascertained by CT or for cutaneous and superficial lesions, by caliper measurement with digital photography. CT preferred for all lesions where possible. PET imaging will be performed, but not used for the primary purpose of measuring response.
* BRAF V600 mutation positive on immunohistochemistry or a local molecular test (e.g. Oncofocus): a. A positive V600E immunohistochemistry stain at study entry should be formally quantified with a local molecular test following study entry (e.g. Oncofocus); b. Molecular BRAF mutation status should preferentially be confirmed using tissue taken from the presenting stage III / IV disease. Alternatively, archival primary tissue is also acceptable to confirm BRAF mutation status.
* Able to swallow and retain oral medication
