Study Details

Study Description

Brief Summary

Up to 18 women with ovarian cancer will administer up to two injections of SPL-108 daily in combination with weekly doses of Paclitaxel. They will be monitored for safety and efficacy for up to 6 months, until disease progression or unacceptable toxicity.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

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.

Outcome Measures

Primary Outcome Measures

  1. Incidence of Adverse Events (Safety) [Until dose-limiting toxicity, disease progression or 6 months]

    Includes adverse events, laboratory data, physical examination findings, vital signs, weight and ECOG Performance Status

Secondary Outcome Measures

  1. Response to Investigational Product [Until dose-limiting toxicity, disease progression or 6 months]

    Objective response (OR) through imaging assessments

  2. Response to Investigational Product [Until dose-limiting toxicity, disease progression or 6 months]

    Objective response (OR) through changes in CA 125 levels

  3. Response to Investigational Product [Until dose-limiting toxicity, disease progression or 6 months]

    Objective response (OR) as assessed through changes in Quality of Life (FACT-O Questionnaire)

  • Liver aminotransferase levels greater than 3 times the laboratory's upper limit of normal (greater than 5 times the laboratory's upper limit of normal if the liver is known to be involved with tumor)

  1. Contraindication to the use of PTX

  2. Pregnancy or breast-feeding at time of Screening and throughout the study.
