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 have spread to other parts of the body (metastatic) or cannot be removed by surgery (unresectable). Dabrafenib, trametinib, and navitoclax may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Description: Determined by dose-limiting toxicities graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events.
Measure: Recommended phase II dose of the combination of dabrafenib, trametinib, and navitoclax (Phase I) Time: Up to 28 daysDescription: Assessed per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, in the cohort of patients treated with dabrafenib, trametinib, and navitoclax (DTN). The proportion of patients with a best response of CR will be presented with a 95% confidence interval calculated using the method of Atkinson and Brown.
Measure: Proportion of patients with a complete response (CR) (Phase II) Time: Up to 4 weeks after last study treatmentDescription: A comparison between the maximal tumor regression for patients treated with DTN and dabrafenib and trametinib (DT) will be conducted using a Wilcoxon rank-sum test.
Measure: Maximal degree of tumor regression (Phase II) Time: Up to 4 weeks after last study treatmentDescription: PFS will be summarized using the Kaplan-Meier. Log-rank tests will be used to assess for indications of differences between the two treatment modalities.
Measure: Progression free survival (PFS) (Phase II) Time: Time from start of treatment to time of progression or death, whichever occurs first, assessed for up to 4 yearsDescription: OS will be summarized using the Kaplan-Meier. Log-rank tests will be used to assess for indications of differences between the two treatment modalities.
Measure: Overall survival (OS) (Phase II) Time: Up to 4 yearsDescription: ORRs will be presented with 95% exact, binomial confidence intervals.
Measure: Objective response rate (ORR) (Phase II) Time: Up to 4 weeks after last study treatmentDescription: Fold changes of TUNEL will be calculated (post/pre). A Wilcoxon rank-sum test will be used to compare the ratios (or equivalently, the difference in the natural logs) of baseline and follow-up levels of TUNEL between DTN and DT treatment arms.

Measure: Change in phosphatase and tensin homolog (PTEN) status Time: Baseline to up to 1 weekDescription: Fold-changes in assay response will be calculated (post/pre). Fold changes in the assay will be compared across RECIST responses using the Kruskal-Wallis test. In addition, for assay-based response or progression, the proportions of patients with CR/partial response (PR), stable disease (SD), or progressive disease (PD) will be presented with exact 90% confidence intervals. Assay performance data will be compared with response. The proportions will be summarized and compared using exact confidence intervals. Behavior of the blood assay will be summarized graphically.
Measure: Fold changes in BRAF-mutation assay Time: Baseline to up to 4 weeks after last study treatmentDescription: Assay fold changes will be compared with fold changes in tumor burden (post/pre). The relationship will be summarized graphically and using the Spearman rank correlation. Differences in the behavior of the assay will be explored using a general linear model of log (fold-change) with study, baseline tumor burden, and log (fold-change tumor burden) as predictors.
