Rochester, Minn.
The primary objective of this study is to determine the safety profile of SX-682 alone and in combination with pembrolizumab in subjects with metastatic melanoma, including the maximum dose that can be administered until adverse effects prevent further dose increases (i.e., the MTD or recommended phase 2 dose), and the dose-limiting toxicity (DLT).
The secondary objectives are to evaluate the efficacy of SX-682 in combination with pembrolizumab on the basis of the objective response rate, the duration of response, and the rate of progression, and to characterize the single-dose and multidose pharmacokinetic (PK) profile of SX-682.
