|Condition or disease||Intervention/treatment||Phase|
|Stage IV Melanoma Stage III Melanoma Advanced Melanoma||Drug: Pembrolizumab with All-Trans Retinoic Acid||Phase 1 Phase 2|
- To identify the MTD and RP2D of the combination of pembrolizumab and ATRA.
- Describe the safety and toxicity of combined treatment with pembrolizumab and all-trans retinoic acid (ATRA) [brand name VESANOID] in melanoma patients.
- To assess the anti-tumor activity in terms of a). The reduction in MDSC (immunosuppressive myeloid -derived suppressor cells) frequency and suppressive function (measured as a continuous variable)in peripheral blood of advanced melanoma patients undergoing pembrolizumab and VESANOID combination therapy. b). progression free survival.
- To determine the clinical outcomes with tumor-specific T cell responses.

|Official Title:||Pembrolizumab and All-Trans Retinoic Acid in Combination Treatment of Advanced Melanoma|

Experimental: Pembrolizumab with All-Trans Retinoic Acid
Patients will receive pembrolizumab infusions every three weeks. Patients will also receive 3 days of all-trans retinoic acid treatment surrounding each of the first 4 infusions of pembrolizumab, beginning one day prior to the infusion (a total of 12 days of all-trans retinoic acid).
Drug: Pembrolizumab with All-Trans Retinoic Acid
All the patients will receive 200mg Q3W pembrolizumab treatment plus the supplemental treatment of 150 mg/m2 All-Trans Retinoic Acid orally for 3 days surrounding each of the first four infusions of pembrolizumab
- Maximally Tolerated Dose (MTD) and the Recommended Phase 2 Dose (RP2D) of the combination of pembrolizumab and All-Trans Retinoic Acid [ Time Frame: 5 years ]MTD is defined as the highest dose level with no more than 3 DLT reported in 6 DLT-evaluable subjects. A target toxicity rate of approximately 33% of all 24 patients will be used to establish the RP2D.
- Dose-Limiting Toxicity (DLT) for the combined treatment of pembrolizumab and All-Trans Retinoic Acid for each patient [ Time Frame: 5 years ]Toxicity will be evaluated according to NCI CTCAE Version 4.0. A dose limiting toxicity (DLT) will be defined as any grade 3 or higher related to VESNOID and/or Pembrolizumab.
- The anti-tumor activity for each patient [ Time Frame: 5 years ]Anti-tumor activity will be determined by the reduction in MD (immunosuppressive myeloid-derived suppressor cells) frequency and suppressive function (measured as a continuous variable) in peripheral blood of advanced melanoma patients undergoing the combined treatment of pembrolizumab and All-Trans Retinoic Acid
