Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 99 Years|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

This is an exploratory (n=10-12 evaluable patients), open-label, single-arm, phase II study in patients with 'non-inflamed' unresectable regional or distant metastatic melanomas irrespective of prior treatment with PD-1/PD-L1 pathway inhibitors. The primary endpoint is to assess the incidence of histopathologic conversion of non-inflamed melanomas from patients with metastatic melanoma to 'inflamed' melanoma following single-agent entinostat "priming" (entinostat monotherapy). More specifically, patients with metastatic melanomas that have no evidence of tumor-infiltrating or tumor-associated lymphocytes (TIL/TAL), based on standard hematoxylin and eosin (H&E) staining of representative tumor sections (non-inflamed melanomas) will receive weekly entinostat for 3 weeks in cycle 1 (entinostat monotherapy; 5mg PO, qwk on D1, D8, D15 of cycle 1; cycle length = 21 days). Mandatory tumor tissue biopsies will be performed in the end of cycle 1, beginning of cycle 2 (day 21±2 days), immediately before treatment with concurrent entinostat (once weekly × 3) and pembrolizumab (200 mg q3wks) in cycles 2-9 (see section 5.2.1 drug dosing schema). Correlative studies will be performed at baseline and in the end of cycle 1, beginning of cycle 2 (day 21±2 days) to assess whether: (a) 3 weeks of entinostat monotherapy converts TIL/TAL-absent melanomas to TIL/TAL-present by histopathologic (H&E stain) analysis, (b) 3 weeks of single-agent entinostat induces changes in gene expression profiling by assessing distinct signatures as defined by RNA-sequencing signatures (RNA-seq; 'immune-high', innate anti-PD-1 resistance [IPRES], and epigenetic 1-3), (c) 3 weeks of single-agent entinostat induces changes in histone-accessible DNA by performing formaldehyde-assisted isolation of regulatory elements (FAIRE)4, (d) conversion of non-inflamed to inflamed melanomas by single-agent entinostat and/or antitumor response to the entinostat-pembrolizumab combination is associated with a baseline signature that consists of distinct somatic mutation gene profile, global histone modification profile in melanoma tissue or peripheral blood mononuclear cells (PBMC), and/or abundance of entinostat targets in melanoma cells (HDAC 1, 2, 3, and 11). Up to 12 evaluable patients will be treated with entinostat plus pembrolizumab for up to 27 weeks (approximately 6 months) based on clinical benefit. Patients who continue to have clinical benefit at 27 weeks may continue therapy with pembrolizumab or any other PD-1/PD-L1 inhibitor, as per standard of care.Secondary exploratory endpoints involve: (a) assessment of antitumor response of entinostat administered concurrently with pembrolizumab at week 10 (or earlier if patient progresses), based on response rate per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). (b) assessment of the progression-free survival (PFS) rate at 27 weeks (approximately 6 months) of the entinostat-pembrolizumab combination. (c) determine the safety of the entinostat-pembrolizumab combination in patients with metastatic melanoma per NCI Common Terminology Criteria for Adverse Events (NCI-CTCAE). (d) assessment of other exploratory biomarkers in tumor tissue and peripheral blood.
Experimental: Single Arm: Entinostat + Pembrolizumab
Subjects in this trial will be administered entinostat, 5mg PO, once weekly (D1, D8, D15 of a 21-day cycle) starting on day 1 of study treatment. Pembrolizumab, 200 mg will be administered intravenously (IV) every 3 weeks and initiated at cycle 2 after the mandatory research tumor biopsy in the end of cycle 1, beginning of cycle 2 (day 21±2 days),. Combination therapy with both agents will continue if subject is receiving clinical benefit from therapy for up to 27 weeks (8 cycles of combination therapy or approximately 6 months). Study therapy will be discontinued for intolerable toxicity, disease progression or for other reasons at the discretion of the investigator.
Drug: - Entinostat
Oral drug 5 mg taken once weekly for up to nine 3-week (21 day) cycles. Take on an empty stomach i.e., at least 2 hours after a meal and at least 1 hour before the next meal. On days when entinostat is administered on the same day as pembrolizumab, entinostat should be taken before the pembrolizumab infusion.
Drug: - Pembrolizumab
200 mg IV starting on Day 22 (cycle 2, Day 1) given every 3 weeks for up to 8 cycles.
