E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To estimate the frequency of the v-raf murine sarcoma viral oncogene homolog B1 (BRAF) V600 mutation in a new mutation analysis triggered by a mutant plasma cell-free DNA (cfDNA) test result, for patients with BRAF wild-type status based on a prior test result on tissue |
|
E.2.2 | Secondary objectives of the trial |
To investigate the clinical outcome of all patients, as well as broken down for patients for whom treatment is based on the mutation identified by the prior test result on tissue, and patients for whom treatment is based upon the mutation identified on the new tissue analysis, triggered by the mutant plasma cfDNA test result
To investigate the correlation of the initial concentration of the BRAF V600 mutation on cfDNA in plasma with progression-free survival time and duration of response, for all treated patients
To estimate the sensitivity and specificity, and the positive and negative predictive value of the results of plasma testing with respect to the prior test result on tissues
To characterize the toxicity profile in patients receiving vemurafenib plus cobimetinib |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Presence and concentration of the BRAF V600 mutation and the NRAS mutation measured on plasma cfDNA will be recorded during treatment with vemurafenib and cobimetinib.
(Please refer to the protocol) |

c. Effective forms of contraception include surgical sterilization, a reliable barrier, method with spermicide, birth control pills, or contraceptive hormone implants. Please note that potential interactions between vemurafenib and hormonal contraceptives may decrease the effectiveness of hormonal contraceptives.
d. d. Male patients who are surgically sterilized are required to use barrier methods of contraception
Disease-specific Inclusion Criteria:
- Patients with histologically confirmed cutaneous melanoma, either unresectable Stage IIIc or Stage IV metastatic melanoma, as defined by AJCC 7th edition

b. Use of prior chemotherapy or immunotherapy (incl. treatment with an anti-PD1, or anti-PDL1 or anti-CTLA-4 monoclonal antibody) within 4 weeks before first study drug administration
Exclusion Criteria Based on Organ Function:

- Major surgery or traumatic injury within 14 days prior to first dose of study treatment
- History of malabsorption or other condition that would interfere with absorption of study drugs
- the following foods/supplements are prohibited at least 7 days prior to initiation of and during study treatment:
a) St. John’s wort or hyperforin (potent CYP3A4 enzyme inducer)
b) Grapefruit juice (potent cytochrome P450 CYP3A4 enzyme inhibitor)
