The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.

Myrexis Inc.

The purpose of this study is to see how safe the study drug is and to determine the best dose to use in cancer patients in the future.

The study drug is designed to reduce the activity of a protein known as "heat shock protein 90", or "Hsp90". Hsp90 is found in every cell in the human body and normally helps those cells (and the body) cope with stressful situations. In certain cancers, however, Hsp90 helps the cancer cells survive and grow. By reducing the activity of Hsp90, the study drug may slow the growth, and reduce the survival, of those cancer cells.

Condition Intervention Phase
Cancer Drug: MPC-3100 (an Hsp90 inhibitor) Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: Phase 1 Study of MCP-3100 in Patients With Refractory or Relapsed Cancer

Secondary Outcome Measures:
  • Study Drug Pharmacokinetics [ Time Frame: Cycle 1 ]
  • Evidence of anti-tumor activity of study drug. [ Time Frame: After each odd cycle and end of study. ]

Enrollment: 26
Study Start Date: June 2009
Study Completion Date: June 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: MPC-3100 (an Hsp90 inhibitor)

Detailed Description:
This is a dose escalation study. As subjects participating in the study tolerate a specific dose level, the new subjects entering will be given a higher dose of the study drug.
