Study 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.
