NCT04593758
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.
NCT02470273
The purpose of this study is to calculate the sensitivity and specificity of a novel imaging device and associated software algorithm in detecting early stage melanoma versus nevi of the skin. The instrument, which was invented by the PI, for the purposes of this study, will be loaned to three external (to Rockefeller) institutions and used on patients who are scheduled for biopsy of pigmented lesions. The purpose of correlating the output screening result of the novel device and the output diagnosis of the gold standard histology analysis procedure is so that these two diagnoses can be compared to generate the number of true positives, true negatives, false positives and false negatives for the novel device. The purpose of disseminating the device to the external institutions is to achieve the appropriate power such that the specificity can be evaluated at 99% sensitivity. The rationale for the power needed in the study is that in order to be clinically useful, the device needs to be extremely sensitive (i.e. 99%) because false negative diagnosis is a dangerous situation, leading to potential progression of melanoma, the most deadly form of skin cancer.
