eoadjuvant treatment with the combination of vemurafenib and cobimetinib (GDC-0973) in limited metastasis of malignant melanoma (AJCC stage IIIC/IV) and integrated biomarker study: a single armed phase II EADO trial

Phase 1
Conditions
Patients with metastatic melanoma, stage IIIC or IV (American Joint Committee on Cancer 2010) with hardly resectable/unresectable limited metastasis positive for the BRAF V600 mutation, which are expected to become resectable (R0) due to tumor shrinkage under vemurafenib + cobi-metinib.

Inclusion Criteria

1.Adult patients, = 18 years of age
2.Willing and able to give informed consent
3.Metastatic melanoma, stage IIIC or IV (American Joint Committee on Cancer 2010)
4.ECOG 0-1
5.MAP-kinase pathway inhibitor treatment-naïve
6.Positive for BRAF V600 mutation, preferentially to be shown from metastatic tumor tissue
7.Decision of eligibility for neoadjuvant combined vemurafenib and cobimetinib treatment by interdisci-plinary tumor board. Patient with limited numbers of metastases and few organ systems involved should be selected, making surgical resection after neoad-juvant treatment probable.
8.Measurable disease by Response Evaluation Criteria In Solid Tumors (RECIST V1.1) criteria
9.Adequate hematologic and organ function as defined by:
•ANC = 1.5 × 109/L
•Platelets = 100 × 109/L
•Hemoglobin = 9 g/dL
•Albumin = 2.5 g/dL
•Bilirubin = 1.5 × the upper limit of normal (ULN)
•AST, ALT, and alkaline phosphatase = 3 × ULN,
except patients with documented liver metasta-ses:
AST and/or ALT = 5 × ULN
•Patients with documented liver or bone metasta-ses: alkaline phosphatase = 5 × ULN
•Serum creatinine = 1.5 × ULN
10.For fertile men: effective contraception during treat-ment and for 6 months after completion in such a manner that the risk of pregnancy is minimized
11.For women of childbearing potential, negative preg-nancy test performed within 28 days prior study en-rolment, preferably as close to the first dose as pos-sible, and agrees to use adequate contraception from pregnancy test onwards, through the dosing period, and for at least 6 months after the last dose of investigational product as:
•complete abstinence from sexual intercourse
•oral contraceptive, either combined or progesto-gen alone
•injectable progestogen
•implants of levonorgestrel
•estrogenic vaginal ring
•percutaneous contraceptive patches
•intrauterine device (IUD) or intrauterine system (IUS) with a documented failure rate of less than 1% per year
•male partner sterilization (vasectomy with docu-mentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject
•double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository)
