Safety and Pharmacology of SNX-5422 Plus Carboplatin and Paclitaxel in Subjects With Solid Tumors
Heat shock protein 90 (Hsp90) is a chemical in the body that is involve in the promotion of cancer. SNX-5422 is an experimental drug that blocks Hsp90.
|Study Design:||Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase 1, Open-label, Dose-escalation Study of SNX 5422 Plus Carboplatin and Paclitaxel in Subjects With Selected Solid Tumors.|
- Number of patients with dose limiting toxicities [ Time Frame: First 28 day cycle ] [ Designated as safety issue: Yes ]Number of patients with dose-limiting toxicities defined as adverse events or laboratory abnormalities of Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 ≥ Grade 3 after commencing study treatment that are not clearly related to disease progression
- Number of patients with adverse events as a measure of tolerability [ Time Frame: Day 28 of each cycle ] [ Designated as safety issue: Yes ]Frequency and severity of adverse events
- Changes in ECG, vital signs, laboratory or physical examination [ Time Frame: Day 28 of each cycle ] [ Designated as safety issue: Yes ]Changes in ECG, vital signs pr physical or laboratory examinations from baseline
- Tumor response [ Time Frame: Every 12 weeks ] [ Designated as safety issue: No ]Tumor response using the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria (version 1.0) assessed by CT scan (or MRI) when combined with carboplatin and paclitaxel and for SNX-5422 when given alone during the maintenance part.
|Study Start Date:||November 2013|
|Estimated Study Completion Date:||August 2015|
|Estimated Primary Completion Date:||June 2015 (Final data collection date for primary outcome measure)|
Open label administration of SNX-5422 capsules every other day (QOD) for 21 days of a 28 day cycle. Dose escalation will be based on safety outcomes defined as 1 or less dose limiting toxicities during the first 28 day cycle at any dose level. During the dose escalation phase, subjects will receive carboplatin and paclitaxel once every 21 days for a total of 4 courses. During the maintenance phase, SNX-5422 at the MTD will be dosed every other day (QOD) for 21 days of a 28 day cycle.
Capsule dosed every other day for 21 days out of a 28 day cycle. Dose escalation based on safety. Maintenance doses at the maximum tolerated dose.
Heat shock protein 90 (Hsp90) chaperone proteins stabilize well over 200 different known client proteins helping them to fold correctly as they take up their rightful positions in the cell. Inhibitors of the chaperone protein Hsp90 are of current interest because of the central role of Hsp90 in the maturation and maintenance of numerous proteins that are critical for tumor cell viability and growth. SNX-5422 is a pro-drug of SNX-2112, a potent, highly selective, small-molecule inhibitor of the molecular chaperone heat shock protein 90 (Hsp90). The study will determine the maximum tolerated dose (MTD) of SNX-5422 when combined with carboplatin plus paclitaxel in selected solid tumors and assess the safety and efficacy of SNX-5422 alone dosed at the MTD as maintenance therapy in selected solid tumors treatment.
