The goal of this trial in Phase I is to determine the maximally tolerated dose (MTD) of hydroxychloroquine in combination with devimistat in patients with relapsed or refractory Clear Cell Sarcomas of the Soft Tissue and to describe the full toxicity profile. In Phase II, the goal is to evaluate the response rate [Complete Rate (CR) + Partial Rate (PR)] of the combination of devimistat and hydroxychloroquine in patients with relapse or refractory Clear Cell Sarcoma of the Soft Tissue and to evaluate the PK and PK/PD profiles for efficacy and safety of the combination of devimistat and hydroxychloroquine.
