Brief Summary:
This phase II trial studies how well encorafenib and binimetinib work before surgery in treating patients with BRAF V600-mutated stage IIIB-D melanoma that has spread to the lymph nodes. Encorafenib and binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. This trial also studies how well 18F-FLT positron emission tomography (PET)/computed tomography (CT) works in predicting the response of melanoma to encorafenib and binimetinib. 18F-FLT is an imaging agent, sometimes called a tracer. PET and CT are types of imaging scans. Using 18F-FLT PET/CT together with encorafenib and binimetinib may provide more information on melanoma over time.

Arm Intervention/treatment
Experimental: Treatment (18F-FLT, PET/CT, encorafenib, binimetinib, surgery)

NEOADJUVANT TREATMENT: Patients receive 18F-FLT IV and undergo a PET/CT scan approximately 60 minutes later. Within 2 weeks, patients receive encorafenib PO QD and binimetinib PO BID on days 1-28. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive 18F-FLT IV and undergo a second PET/CT scan approximately 60 minutes later.

SURGICAL RESECTION: Within 2 weeks of completing therapy with encorafenib and binimetinib, patients undergo surgery.

ADJUVANT TREATMENT: Within 2-7 days after surgery, patients resume treatment with encorafenib PO QD and binimetinib PO BID on days 1-28. Treatment repeats every 28 days for up to 11 cycles in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures :
  1. Pathologic complete response (pCR) rate [ Time Frame: Up to 5 years ]
    Will be estimated and 90% confidence intervals (CI) adjusting for the first stage analysis will be provided.

  2. Change in fluorothymidine F-18 (18F-FLT) positron emission tomography (PET)/computed tomography (CT) uptake [ Time Frame: Baseline up to 2 cycles of treatment (8 or 9 weeks of neoadjuvant therapy) ]
    Will be compared among patients with and without a pCR. Distributional summaries of the continuous percent change in 18F-FLT PET/CT maximum standardized uptake value (SUVmax) will be reported, where percent change is defined as (baseline SUVmax - post-neoadjuvant SUVmax)/(baseline SUVmax)*100%. The comparison of percent change in SUVmax between pCR and non-pCR patients will be performed using a one-sided nonparametric Wilcoxon rank sum test with an alpha level of 0.05. Will also report distributional summaries and comparisons for percent change in 18F-FLT PET/CT peak SUV (SUVpeak); however, the prespecified primary comparison will be based on 18F-FLT PET/CT SUVmax.


Secondary Outcome Measures :
  1. Overall survival (OS) [ Time Frame: From time of enrollment to death from any cause, assessed up to 5 years ]
    OS distributions will be estimated using the Kaplan-Meier method. Median OS will be described with 95% confidence intervals. Clinical data from unevaluable patients will be summarized separately.

  2. Disease-free survival (DFS) [ Time Frame: From complete surgical resection to disease progression or death (whichever comes first), assessed up to 5 years ]
    DFS distributions will be estimated using the Kaplan-Meier method. Median DFS will be described with 95% confidence intervals. Clinical data from unevaluable patients will be summarized separately.

  3. Response rate [ Time Frame: Up to 5 years ]
    Will be evaluated based on international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors guideline (version 1.1) and estimated with 95% confidence interval. Clinical data from unevaluable patients will be summarized separately.

  4. Incidence of adverse events (AEs) [ Time Frame: Up to 5 years ]
    Will be graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version(v.) 5.0. All treatment-emergent and baseline adverse events and hematological/biochemical toxicities based on laboratory measurements, as well as drug related AEs, will be summarized by NCI CTCAE v. 5.0 worst grade. The incidence of deaths and treatment-emergent serious adverse events (defined as number of patients experiencing the AE divided by all treated patients) will be summarized. Also, the incidence of adverse events leading to discontinuation of investigational product and/or withdrawal from the study will be summarized and listed.

  5. Change in CD8 positive (+) tumor infiltrating lymphocytes [ Time Frame: Baseline up to 2 cycles of treatment (8 or 9 weeks of neoadjuvant therapy) ]
    Will be based on the two-sample t-test using two-sided type I error rate of 0.1. If normality assumption is not appropriate, Wilcoxon rank sum test will be used during the analysis. Using the median change value, cases will be divided to high and low change groups. Will be assessed and summarized using the descriptive statistics. Will be compared among patients achieving a pCR versus no pCR.

  6. Change in CD8+ T cell infiltration in tumor or tumor bed [ Time Frame: Baseline up to 2 cycles of treatment (8 or 9 weeks of neoadjuvant therapy) ]
    Will be based on the two-sample t-test using two-sided type I error rate of 0.1. If normality assumption is not appropriate, Wilcoxon rank sum test will be used during the analysis. Using the median change value, cases will be divided to high and low change groups. Will be assessed and summarized using the descriptive statistics

  7. Concordance of pCR [ Time Frame: Up to 5 years ]
    The concordance of pCR assessed based on local review versus central pathology review will be evaluated. Kendall's Tau test will be used for this comparison.

  8. Post-neoadjuvant 18F-FLT PET/CT uptake [ Time Frame: Up to 8 weeks of neoadjuvant therapy ]
    Will be compared among patients with and without a pCR. Distributional summaries of the post-neoadjuvant 18F-FLT PET/CT SUVmax will be reported. The comparison SUVmax between pCR and non-pCR patients will be performed using a one-sided nonparametric Wilcoxon rank sum test with an alpha level of 0.05. Will also report distributional summaries and comparisons for post-neoadjuvant in 18F-FLT PET/CT peakSUV.

  9. Optimal threshold for prediction of pathologic complete response [ Time Frame: Baseline up to 8 weeks of neoadjuvant therapy ]
    Will be estimated using change in 18F-FLT PET/CT uptake. Diagnostic performance of percent change in 18F-FLT PET/CT SUVmax (from the baseline scan to the post-neoadjuvant scan) as a marker for pCR status will be assessed using receiver operating characteristic curve (ROC) analysis. In particular, the empirical area. The corresponding performance of the optimal threshold (measured via sensitivity and specificity) will be estimated using cross-validation under the receiver operating characteristic curve (ROC AUC) will be reported, along with corresponding 95% confidence interval. In addition, will formally test if the ROC AUC exceeds 0.5 using a one-sided test with an alpha level of 0.05. The optimal threshold (binary cutpoint) of continuous percent change in SUVmax will be estimated by means of the Youden index. A 95% confidence interval for the optimal threshold will be estimated using the bootstrap technique to properly reflect sampling variability.

  10. Change in 18F-FLT PET/CT uptake [ Time Frame: Baseline up to 8 weeks of neoadjuvant therapy ]
    The correlation between percent change in continuous SUVmax and percent change in the continuous Ki67 score will be estimated using the Spearman correlation coefficient. A one-sided correlation test with null hypothesis of zero correlation will be conducted at alpha level of 0.05. The corresponding confidence interval for the estimated Spearman correlation coefficient will also be reported. Correlation between change in 18F-FLT PET/CT and the early change in tumor cell Ki-67 (from baseline to the week 2 interim biopsy) will also be separately estimated. The corresponding correlation with percent change in 18F-FLT PET/CT SUVpeak will also be reported.


Other Outcome Measures:
  1. Change in Ki-67 status in tumor or tumor bed [ Time Frame: Baseline up to 2 cycles of treatment (8 or 9 weeks of neoadjuvant therapy) ]
    Ki-67 immunohistochemistry in tumor cells will be graded as a percentage of total number of tumor cells with nuclear staining (to the nearest 10%) over 10 high powered fields (at 20 x magnification).
