Study Details

Study Description

Brief Summary

This study is for patients with advanced solid tumors. The purpose of this study is to test the safety and effectiveness of a new combination of drugs, CS-7017 and Bexarotene in patients with advanced cancer. CS-7017 and Bexarotene both have many effects on cancer cells, including stopping cancer cells from growing and dividing, and causing the cancer cells to die. CS-7017 and Bexarotene work on cancer cells in a similar manner and both drugs together may have an even greater effect against cancer cells, hopefully, increasing the killing of cancer cells.

CS-7017 is an investigational or experimental anti-cancer agent that has not yet been approved by the Food and Drug Administration (FDA) for use in any type of cancer. Bexarotene is an anti-cancer agent that has been approved by the FDA for patients with a specific type of cancer, cutaneous T-cell lymphoma.

This study will help find out what effects the combination of drugs, CS-7017 and Bexarotene, has on cancer. This research is being done because it is not known if CS-7017 is safe to be given with Bexarotene.

Arms and Interventions

Arm Intervention/Treatment
Experimental: CS-7017 and Bexarotene

Combination of CS-7017 and Bexarotene

Drug: CS-7017 and Bexarotene
CS-7017 will be administered orally, twice daily for 28 days of each 28-day cycle in escalating doses depending on cohort patient is assigned to. Bexarotene will be administered orally once daily for 28 days of each 28-day cycle. The dose a patient receives will depend on which cohort the patient is assigned to.

  • Outcome Measures

    Primary Outcome Measures

    1. Maximum Tolerated Dose [12 months]

      The highest dose at which < 1 out of 6 subjects experienced a dose-limiting toxicity

    Secondary Outcome Measures

    1. Response rate [4 months]

      Complete response + partial response

    2. Disease control rate [4 months]

      Response rate + stable disease

    3. Pharmacodynamic effects [Prior to treatment, Just prior to Day 1 and just prior to Day 15 of cycle 1]

      PPAR-gamma and RXR analysis by immunohistochemistry; Tumor staining for the following PPAR-gamma regulated genes: Cyclin D1, p16, p18, p21, p27, and c-myc.

    4. Pharmacokinetics [Day -7 prior to first dose of CS-7017, Day 1, and Day 15 of Cycle 1]

      Trough serum levels of CS-7017 and its metabolites
