Brief summary: The purpose of this study is to obtain QTc data, to assess the effects of tivozanib on ECG morphology, and to determine the pharmacokinetic pharmacodynamic (PK-PD) relationship between any observed changes in cardiac repolarization (defined by QTcF duration) and the serum concentration of tivozanib.

Detailed description: Tivozanib is a novel and potent pan-vascular endothelial growth factor (VEGF) receptor (VEGFR) tyrosine kinase inhibitor with potent activity against all 3 VEGFRs (VEGFR-1, -2, and -3). In nonclinical models and studies performed in humans, tivozanib has shown strong antiangiogenesis and antitumor activity.

This study is an open-label, non-randomized, exploratory single-arm trial evaluating the ECG and pharmacokinetic (PK)-ECG relationship, if any, of tivozanib in subjects with advanced solid tumors.

The purpose of this study is to evaluate the ECG intervals and morphology following treatment with tivozanib in subjects with advanced solid tumors and to determine the relationship, if any, of the change in QTc duration with serum concentration of tivozanib over time in subjects with advanced solid tumors.

Eligibility criteria: Inclusion Criteria

* Males or females, ≥18 years of age;
* Diagnosis of an advanced solid tumor malignancy with histological or cytological evidence;
* Advanced malignancy, metastatic or unresectable, that has recurred or progressed following standard therapy or failed standard therapy; or for which no standard therapy currently exists; or for which subject is not a candidate, or is unwilling to undergo standard therapy;
* Tumor is not currently amenable to curative surgical intervention;
* Recovery from the effects of any prior surgery, radiotherapy, or systemic antineoplastic therapy;

Exclusion Criteria

- Women who are breast-feeding, pregnant, or intend to become pregnant;

* Baseline ECG, QTcF \> 480 ms. If the screening QTcF is \> 480 ms, this may be repeated once and if the QTcF is ≤ 480 ms the subject can be enrolled;
* Any of the following hematologic abnormalities:

  • hemoglobin \< 9.0 g/dL;

  • Absolute neutrophil count \< 1500 per mm3;
  * platelet count \< 100,000 per mm3;
  * INR \> 1.5 x upper limit of normal (ULN);
* Any of the following serum chemistry or urine abnormalities:

  • total bilirubin \> 1.5 × ULN (or \> 2.5 × ULN for subjects with Gilbert's syndrome);
  * AST or ALT \> 2.5 × ULN (or \> 5 × ULN for subjects with liver metastasis);
  * alkaline phosphatase \> 2.5 × ULN (or \> 5 × ULN for subjects with liver or bone metastasis);
  * creatinine \> 2.0 × ULN;
  * proteinuria \> 3+ by urinalysis;
* Non healing wound, bone fracture, or skin ulcer;
* Active peptic ulcer disease, inflammatory bowel disease, ulcerative colitis, or other gastrointestinal condition with increased risk of perforation; history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 4 weeks prior to administration of first dose of study drug;
* Serious/active infection or infection requiring parenteral antibiotics or antifungal therapy;
* Inadequate recovery from any prior surgical procedure or major surgical procedure within 4 weeks prior to administration of first dose of study drug;
* Significant thromboembolic or vascular disorders or surgery within 6 months prior to administration of first dose of study drug, including but not limited to:

  • deep vein thrombosis;

  • pulmonary embolism;

  • cerebrovascular accident or transient ischemic attack;

  • peripheral arterial ischemia \> Grade 2;

  • coronary or peripheral artery bypass graft;
* Significant bleeding disorders within 6 months prior to administration of first dose of study drug, including but not limited to:

  • hematemesis, hematochezia, melena or other gastrointestinal bleeding ≥ Grade 2;
  * hemoptysis or other pulmonary bleeding ≥ Grade 2;
  * hematuria or other genitourinary bleeding ≥ Grade 2;
* Currently active second primary malignancy, including hematologic malignancies (leukemia, lymphoma, multiple myeloma, etc), other than non melanoma skin cancers, non-metastatic prostate cancer, in situ cervical cancer and ductal or lobular carcinoma in situ of the breast. Subjects are not considered to have a currently active malignancy if they have completed anti-cancer therapy and have been disease free for \>2 years;

* Sexually active male and pre-menopausal female subjects (and their partners) unless they agree to use adequate contraceptive measures, while on study and for 30 days after the last dose of study drug. All fertile male and female subjects (and their partners) must agree to use a highly effective method of contraception. Highly effective birth control includes (a) IUD plus one barrier method; or (b) two barrier methods. Effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm). Note: Oral, implantable, or injectable contraceptives may be affected by cytochrome P450 interactions, and are not considered effective for this study.

Prohibited 3 weeks prior to first dose and for the duration of the study:

Prohibited 2 weeks prior to first dose and for the duration of the study:

If previously receiving these types of agents, a minimum washout of 1 week and documented PT of \< 1.5 × ULN will be required prior to start of therapy. Full dose anticoagulation with low molecular weight heparin or unfractionated heparin administered subcutaneously is allowed. Low dose oral anticoagulation (eg, 1-2 mg/day warfarin) is allowed provided PT remains \< 1.5 × ULN during the study.
