VECODUE A Phase II Trial of Vemurafenib Plus Cobimetinib in Patients Treated With Prior First-line Systemic Immunotherapy for Inoperable Locally Advanced or Metastatic Melanoma

In the BRIM-3 trial, which was conducted in patients with previously untreated advanced melanoma harboring the BRAF V600E mutation, vemurafenib, a potent inhibitor of mutated BRAF, was associated with prolonged overall survival (OS) and progression-free survival (PFS) compared to dacarbazine. In the same setting, combined use of vemurafenib and cobimetinib, a selective inhibitor of MEK, yielded a significant improvement in PFS and response rate, compared to vemurafenib monotherapy, along with an advantage in OS, which did not cross the pre-specified significance bounderies (COBRIM trial). In treatment-naïve patients with mutated BRAF, both anti PD-1-based immunotherapy and BRAF-targeted agents are feasible therapeutic options, with the former and latter agents being associated with more durable and earlier responses, respectively. As suggested by National Comprehensive Cancer Network (NCCN) guidelines, the use of combined BRAF and MEK inhibitors in patients with progressive disease after immunotherapy, is also feasible, but it is not supported by category 1 evidence, in view of the lack of studies conducted in this setting. The main objective of this phase II trial is to evaluate the efficacy and safety of the combined use of vemurafenib plus cobimetinib in advanced melanoma patients who have received first-line systemic immunotherapy for inoperable locally advanced / metastatic disease.

Name: Cobimetinib

Description: Cobimetinib will be given orally at 60 mg qd on Days 1−21 of each 28-day treatment cycle

Type: Drug

Single arm


Primary Outcomes

Description: OS will be calculated from the first day of treatment until the date of death from any cause.Any patient not know to have died at the time of data analysis will be censored at the time of the last recorded date on which the patient was know to be alive.

Measure: Overall Survival

Time: Patients enrolled will receive study medication until disease progression, unaccettable toxicity, withdrawal of consent or death, whichever comes first, assested up to 24 month

Secondary Outcomes

Description: PFS will be defined as the time from initiation of study treatment to the first occurrence of disease progression or death from any cause, whichever occurs first.PFS will be calculated based on disease status evaluated bythe investigator according to RECIST v1.1

Measure: PFS

Time: Patients enrolled will receive study medication until disease progression, unaccettable toxicity, withdrawal of consent or death, whichever comes first, assested up to 24 month

Description: ORR, defined as the proportion of patients with a best overall response of either complete response (CR) or partial response (PR), will be calculated based on disease status evaluated by the investigator accordingto RECIST v1.1

Measure: ORR

Time: Patients enrolled will receive study medication until disease progression, unaccettable toxicity, withdrawal of consent or death, whichever comes first, assested up to 24 month

Purpose: Treatment

Vemurafenib Plus Cobimetinib in Advanced or Metastatic Melanoma Patients In the BRIM-3 trial, which was conducted in patients with previously untreated advanced melanoma harboring the BRAF V600E mutation, vemurafenib, a potent inhibitor of mutated BRAF, was associated with prolonged overall survival (OS) and progression-free survival (PFS) compared to dacarbazine. --- V600E ---

Melanoma Melanoma (Skin) Melanoma Stage Melanoma In the BRIM-3 trial, which was conducted in patients with previously untreated advanced melanoma harboring the BRAF V600E mutation, vemurafenib, a potent inhibitor of mutated BRAF, was associated with prolonged OS and PFS compared to dacarbazine. --- V600E ---

As evidenced above, vemurafenib inhibits the BRAF V600E kinase, (this mutation is found in 50% to 60% of melanomas), and enables a remarkable clinical response rate, more than 50% and a statistically significant improvement in OS in patients with unresectable stage III and IV melanoma. --- V600E ---

Multiple mechanisms underlie the development of BRAF-I resistance in BRAF V600E melanoma cells including point mutations in MEK1, amplification of mutant BRAF V600E, elevated closely related serinethreonine kinase activity, activating NRAS mutations, increased levels of COT/Tpl2, aberrantly spliced BRAF V600E and growth factor receptor upregulation. --- V600E ---
