简要总结
This phase I/II trial studies the side effects and best dose of dabrafenib, trametinib, and navitoclax and to see how well they work in treating patients with BRAF mutant melanoma or solid tumors that has spread from where it first started (primary site) to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Dabrafenib and trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Navitoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of tumor cells by blocking Bcl-2, a protein needed for tumor cell survival. Giving navitoclax, dabrafenib, and trametinib may help shrink tumors in patients with melanoma.
详细描述
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD), toxicity, and safety profile of navitoclax when given in combination with dabrafenib and trametinib in patients with BRAF-mutant solid tumors. (Phase I) II. To estimate the complete response (CR) rate in patients with BRAF-mutant melanoma treated with dabrafenib, trametinib, and navitoclax as compared to the historical control dabrafenib and trametinib combination (DT). (Phase II) III. To compare the maximal tumor regression in patients with BRAF-mutant melanoma treated with dabrafenib, trametinib versus dabrafenib, trametinib, and navitoclax. (Phase II)
SECONDARY OBJECTIVES:
I. To describe pharmacodynamics effects of treatment with dabrafenib, trametinib, and navitoclax on both serial tumor biopsies and serial blood draws in a small subset of patients treated with BRAF-mutant melanoma. (Phase I) II. To describe the pharmacokinetics of treatment with dabrafenib, trametinib, and navitoclax. (Phase I) III. To compare the progression-free survival (PFS), overall survival (OS), and overall response rate (ORR) in patients with BRAF-mutant melanoma treated with dabrafenib, trametinib, versus dabrafenib, trametinib, and navitoclax. (Phase II) IV. To compare the degree of apoptosis induced in on-treatment biopsies of patients with BRAF-mutant melanoma treated with dabrafenib, trametinib versus dabrafenib, trametinib, and navitoclax. (Phase II) V. To explore other pharmacodynamic effects in on-treatment biopsies of patients with BRAF-mutant melanoma treated with either dabrafenib, trametinib versus dabrafenib, trametinib, and navitoclax including cell proliferation (Ki-67), proteomics (reverse-phase protein microarrays [RPPA]), and B-cell chronic lymphocytic leukemia (CLL)/lymphoma 2 (BCL-2) family gene expression analysis. (Phase II)
OUTLINE: This is a phase I, dose-escalation study of dabrafenib, trametinib, and navitoclax followed by a randomized phase II study.
PHASE I: Patients receive navitoclax orally (PO) once daily (QD) on days -7 to -1 of cycle 1 only. Patients also receive dabrafenib PO twice daily (BID), trametinib PO QD, and navitoclax PO QD days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo electrocardiography (ECHO) or multigated acquisition scan (MUGA), magnetic resonance imaging (MRI) or computed tomography (CT), also undergo biopsy, and collection of blood samples throughout the trial.
PHASE II: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive dabrafenib PO BID and trametinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo ECHO or MUGA, MRI or CT, biopsy, and collection of blood samples throughout the trial.
ARM II: Patients receive navitoclax PO QD days -7 to -1 of cycle 1 only. Patients also receive dabrafenib PO BID, trametinib PO QD, and navitoclax PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo ECHO or MUGA, MRI or CT, biopsy, and collection of blood samples throughout the trial.
After the completion of study treatment, patients are followed up for clinical evaluation at 28 days and every 3 months thereafter until disease progression or death, whichever comes first. For survival follow up, patients are followed every 12 months for 3 years.

- •Patients must have histologically confirmed, BRAF-mutant (V600E/K) melanoma (molecularly confirmed using validated, commercially available assay performed in a Clinical Laboratory Improvement Act \[CLIA\]-approved laboratory) that is metastatic or unresectable and for which standard curative measures do not exist or are no longer effective
- •If test at CLIA-certified lab used a non-Food and Drug Administration (FDA) approved method, information about the assay must be provided; (FDA approved tests for BRAF V600 mutations in melanoma include: THxID BRAF Detection Kit and Cobas 4800 BRAF V600 Mutation Test)
- •Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as \>= 20 mm with conventional techniques or as \>= 10 mm with spiral CT scan, MRI, or calipers by clinical exam
- •Prior therapy is allowed; for patients enrolled in the Phase II portion of the study, patients may have received prior immunotherapy (including high-dose IL-2, ipilimumab, nivolumab, and other anti-PD1/PDL1 antibodies) or chemotherapy; however prior navitoclax, BRAF inhibitor and/or MEK inhibitor therapy will not be allowed
- •Age \>= 18 years. Because no dosing or adverse event data are currently available on the use of navitoclax in combination with dabrafenib and trametinib in patients \< 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials
- •Eastern Cooperative Oncology Group (ECOG) performance status =\< 1 (Karnofsky \>= 70%)
- •Life expectancy of greater than 3 months
- •Leukocytes \>= 3,000/mcL
