Phase I Registration - Exclusion Criteria

• Pregnant women

• Receiving any other investigational agent.
• Other active malignancy ≤3 years prior to registration. EXCEPTIONS: Non-melanotic skin cancer or carcinoma-in-situ of the cervix. NOTE: If there is a history or prior malignancy, they must not be receiving other specific treatment (other than hormonal therapy) for their cancer.

• Received treatment with radiation therapy or investigational therapy ≤28 days prior to registration.
• RCC patients only: Having received chemotherapy prior to study entry within 5 half-lives of the agent (as described in the package insert), or 4 weeks prior to registration (whichever is shorter) with resolution of side effects from therapy to ≤grade 1.
• Known central nervous system or brain metastasis that are either symptomatic or untreated. Note: Patients with neurological symptoms must undergo a CT scan/MRI of the brain to exclude brain metastasis.
  • Note: Subjects with CNS metastases that have been treated and are stable without symptoms for ≥ 4 weeks after completion of treatment are eligible.
• HCC patients only: Cancer potentially amenable to local modalities of therapy or surgical resection.
• Known or suspected allergy or hypersensitivity to any component of TH-302, sorafenib, or any of the sorafenib excipients.
• Any condition that severely impairs patient's ability to swallow whole pills.
• QTc interval >500 msec on baseline EKG.
• Documented history of prolonged QTc interval ≤ 6 months prior to registration.
• Receiving any medication that has documented data or is generally accepted as having increased risk of QT prolongation and/or Torsades de Pointes.
• Receiving any medications or substances that are inducers or strong or moderate inhibitors of CYP3A4, see the protocol for a complete listing.
• Fibrolamellar histology HCC, mixed hepatocholangiocarcinoma, hepatic sarcomas and other non-HCC primary liver tumors.
