Safety and Efficacy Study of Daily SPL-108 Injections In Conjunction With Paclitaxel in Women With Ovarian Cancer

This is an open-label 2-arm trial. Eligible subjects will be screened and enrolled sequentially into 1 of 2 Arms: Arm I: N=6 to 12 subjects, Safety Phase * Cohort 1 SPL-108 x 1 injection daily + 80 mg/m2 PTX weekly on Days 1, 8, and 15 in 28 day cycles * Cohort 2 SPL-108 BID + 80 mg/m2 PTX weekly on Days 1, 8, and 15 in 28 day cycles For Arm I, at least 1 week will elapse between Dose 1 for each subject. In Cohort 1, 3 subjects will be enrolled: if 1 dose-limiting toxicity (DLT) occurs, 3 subjects will be added at this dose level; if 0/3 or 1/6 DLTs occur, Cohort 2 will initiate enrolling subjects; if 2 or more DLTs occur at this dose level, subjects will not be enrolled in Cohort 2 and the trial will be terminated. In Cohort 2, 3 subjects will be enrolled: if 1 DLT occurs, 3 subjects will be added at this dose level; if 0/3 or 1/6 DLTs occur, Arm II will initiate enrolling subjects at the SPL-108 BID dose; if 2 or more DLTs occur, Arm II will initiate enrolling subjects at the SPL-108 dose one time each day. Arm II: N=up to 12, Exploratory Expansion Phase • Cohort 3: SPL-108 daily dose (to be determined in Arm I) + 80 mg/m2 PTX weekly on Days 1, 8, and 15 in 28 day cycles. A Safety Committee will meet at the end of each Arm I Cohort as well as periodically to review safety data and make recommendations for trial progression. The primary efficacy outcome, Response Evaluation Criteria in Solid Tumors Committee (RECIST 1.1) criteria, will be assessed on Day 15 of Cycles 2, 4, and 6.
