A Phase I Study of the Safety, Pharmacokinetics, and Anti-Tumor Activity of TH-302 in Patients With Advanced Solid Tumors

Inclusion Criteria:

• Life expectancy of at least 3 months

• Acceptable liver function:

  • Bilirubin ≤ 1.5 times upper limit of normal
  • AST (SGOT) and ALT (SGPT) ≤ 2.5 times upper limit of normal (ULN); if liver metastases are present, then ≤ 5 x ULN is allowed

• Acceptable coagulation status:

  • PT ≤ 1.3 x ULN
  • PTT ≤ 1.3 x ULN
• All women of childbearing potential must have a negative serum pregnancy test and women and men subjects must agree to use effective means of contraception (surgical sterilization or the use or barrier contraception with either a condom or diaphragm in conjunction with spermicidal gel or an IUD) with their partner from entry into the study through 6 months after the last dose

Exclusion Criteria:

• Major surgery, other than diagnostic surgery, within 4 weeks prior to Day 1, without complete recovery
• Active, uncontrolled bacterial, viral, or fungal infections, requiring systemic therapy
• Treatment with radiation therapy, surgery, chemotherapy, targeted therapies (erlotinib, lapatinib, etc.) or hormones within 4 weeks prior to study entry (6 weeks for nitrosoureas or Mitomycin C)
• Patients who participated in an investigational drug or device study within 28 days prior to study entry
• Known infection with HIV, hepatitis B, or hepatitis C
• Patients who have exhibited allergic reactions to a similar structural compound, biological agent, or formulation (containing solutol and/or propylene glycol)
• Females who are pregnant or breast-feeding
• Concomitant disease or condition that could interfere with the conduct of the study, or that would, in the opinion of the investigator, pose an unacceptable risk to the subject in this study
