Brief Summary:
The purpose of the study is to assess the safety and efficacy of BGB324 given together with standard treatment, pembrolizumab or dabrafenib and trametinib, compared to standard treatment alone,

Condition or disease Intervention/treatment Phase
Melanoma Drug: BGB324+pembrolizumab Drug: BGB324+dabrafenib and trametinib Drug: pembrolizumab Drug: dabrafenib and trametinib Phase 1 Phase 2

Detailed Description:
This is an investigator initiated randomized randomized clinical phase 1b/2 clinical trial comparing safety and efficacy of the Axl inhibitor BGB324 in combination with pembrolizumab or dabrafenib+trametinib with that of pembrolizumab or dabrafenib+trametinib alone. Patients with non-resectable stage III or stage IV melanoma will be stratified based on BRAF mutation and tumor load to start dabrafenib+trametinib (BRAF mutation and high tumor load) or pembrolizumab (BRAF wild type or BRAF mutation and low tumor load) in first line. The patients will be randomized 2:1 to receive BGB324 in combination with pembrolizumab or dabrafenib+trametinib or to receive pembrolizumab or dabrafenib+trametinib alone. A 3+3 dose escalation will be performed for the combination of BGB324 and dabrafenib+trametinib. There is a major focus on predictive markers of treatment response evaluated in blood samples and biopsies.

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Patients able to understand and willing to sign a written protocol specific informed consent and 18 years or older at the time of consent

    1. At least one measurable lesion as defined by RECIST 1.1 on CT or MRI scan and
    2. Documented progression of ≥1 measurable lesion
  3. ECOG score 0 to 2 at screening
  4. Availability of fresh or archival tumour tissue sample suitable for evaluation of predictive biomarkers of response
  5. Male patients with female partners of childbearing potential and female patients of childbearing potential willing to practice highly effective birth control from screening, throughout the study and for at least 3 months following the last dose of study treatment (and if female of childbearing potential, has a negative serum pregnancy test in the 7 days before the first dose of study treatment)

Exclusion Criteria:

  1. Prior first line systemic treatment for the treatment of Stage IIIb or Stage IIIc melanoma, including BRAF or MEK inhibitor (adjuvant immunomodulating agent treatment more than 6 months prior to first dose of study treatment is allowed)
  2. Symptomatic central nervous system metastatic lesions as determined by the Investigator (patients with radiographically stable, asymptomatic lesions previously irradiated or surgically resected are eligible provided there is no need for systemic corticosteroids and treatment was completed at least 4 weeks before the first dose of study treatment)
