Melanoma Clinical Trial
Testing Treatment With Encorafenib and Binimetinib Before Surgery for Melanoma With Lymph Node Involvement
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.
PRIMARY CLINICAL OBJECTIVE:
I. To evaluate the pathologic complete response (pCR) rate of neoadjuvant treatment with encorafenib and binimetinib.
SECONDARY CLINICAL OBJECTIVES:
I. To determine response rate (RR) (Response Evaluation Criteria in Solid Tumors [RECIST]), disease-free survival (DFS) and overall survival (OS).
II. To describe correlation of pCR with RR, DFS and OS. III. To assess safety and toxicity.
CORRELATIVE SCIENCE OBJECTIVES:
I. To evaluate CD8 positive (+) T cell infiltration and Ki-67 status in tumor or tumor bed pre, during, and post neoadjuvant treatment and the change in CD8+ tumor infiltrating lymphocyte (TIL) with neoadjuvant treatment and correlate with clinical response.
II. To compare local review for pathologic response with central pathology review.
III. To assess the correlation between change in fluorothymidine F-18 (18F-FLT) PET/CT uptake and change in Ki-67.
I. To compare the change in 18F-FLT PET/CT uptake (from baseline to post-neoadjuvant therapy) among patients with and without pathologic complete response.
II. To compare post-neoadjuvant 18F-FLT PET/CT uptake among patients with and without pathologic complete response.
III. To estimate an optimal threshold for prediction of pathologic complete response using i) change in 18F-FLT PET/CT uptake, and ii) post-neoadjuvant 18F-FLT PET/CT uptake.
IV. To assess the correlation between change in 18F-FLT PET/CT uptake and change in Ki-67.
NEOADJUVANT TREATMENT: Patients receive 18F-FLT intravenously (IV) and undergo a PET/CT scan approximately 60 minutes later. Within 2 weeks, patients receive encorafenib orally (PO) once daily (QD) and binimetinib PO twice daily (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.
After completion of study treatment, patients are followed up every 3 months for 1 year, then every 6 months for 3 years.
