Safety Study of SGX523, a Small Molecule Met Inhibitor, to Treat Solid Tumors

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. Identifier: NCT00607399
Recruitment Status : Terminated

Brief Summary:
SGX523 is a drug which acts by blocking the function of an enzyme called MET. MET activity may be important in growth and survival of some types of cancer. This Phase I trial is studying the safety, side effects, and best dose of SGX523 when given to patients with advanced cancer, and how well it inhibits MET activity in tumors.

  • Pathologic evidence of solid tumor.
  • Failed standard therapy and deemed by the Investigator to be suitable for participation into the trial.
  • Laboratory values (obtained within 10 days prior to enrollment): ANC: >= 1.5 × 109/L; Platelets: >= 100 × 109/L; Hemoglobin: >= 10.0 g/dL (without transfusions); Bilirubin: within normal range; AST, ALT, and alkaline phosphatase: <= 2.5 x ULN without tumor liver involvement; Serum creatinine: within normal limits; Calculated creatinine clearance: >= 60 mL/min/1.73 m2 for patients with creatinine > Institutional Normal Values; PT/PTT/INR: within normal limits.

  • Have an active, uncontrolled bacterial, viral, or fungal infection that requires ongoing systemic therapy.
  • Have a known active infection with HIV, hepatitis B or C.
  • Have psychiatric or seizure disorders that would require therapy or interfere with study participation.
  • Have other severe concurrent nonmalignant disease that could compromise protocol objectives, including malabsorptive conditions.
  • Patients receiving prohibited medications as listed in Appendix E, including drugs categorized as strong inhibitors of CYP3A4 and A5 and drugs known to have a high potential risk of liver toxicity.
  • Have known allergy to SGX523 formulation or its excipients (croscarmellose sodium, lactose monohydrate and magnesium stereate).
  • Patients receiving anti-coagulant therapy.
