Phase I/II Trial of Tivantinib With FOLFOX for the Treatment of Advanced Solid Tumors and Previously Untreated Metastatic Adenocarcinoma of the Distal Esophagus, Gastroesophageal Junction or Stomach

Study Overview
=================
Brief Summary
-----------------
This study is a Phase I/II trial of Tivantinib plus FOLFOX for the treatment of patients with advanced solid tumors. In Phase I the Maximum Tolerated Dose (MTD) will be determined; in Phase II patients with first-line metastatic GE cancer will be treated at the MTD. It is hypothesized that the response rate (RR) will be improved from 45% to at least 65% under this regimen.

Detailed Description
-----------------
This is a Phase I, open-label, non-randomized, dose-escalation study with a Phase II portion planned upon reaching the Maximum Tolerated Dose or recommended Phase II dose (RP2D). Phase I: The first cycle of the Phase I portion of the trial will be considered the Dose Limiting Toxicity evaluation period. Patients with advanced solid tumors will be treated with Tivantinib on Days 1 to 14 and with FOLFOX on Day 1. Following evaluation of the Dose Limiting Toxicities, doses will be escalated/reduced according to the protocol with 3 to 6 patients treated per dose level until the Maximum Tolerated Dose is determined.

Serum creatinine <1.5 X ULN or calculated 24-hour creatinine clearance >40 mL/min. Patients who are on coumadin should have an international normalized ratio (INR) value within the therapeutic range (i.e., 2 to 3 x ULN). Patients who are on stable, chronic doses of coumadin are eligible. PHASE I ONLY •Patients must have histologically confirmed solid tumor malignancy that is metastatic or unresectable and for which standard therapy would include FOLFOX or for which standard curative or palliative measures do not exist or are no longer effective. PHASE II ONLY Histologic documentation of adenocarcinoma of the esophagus, GE junction, or stomach. Metastatic GE cancer as documented by radiologic study or surgical evidence of metastatic disease. No prior chemotherapy for metastatic disease. Previous combined modality therapy for locally advanced disease is allowed if completed ≥6 months prior to recurrence (acceptable chemotherapy drugs include 5-FU, capecitabine, cisplatin, carboplatin, paclitaxel, oxaliplatin, and docetaxel). Prior radiation therapy is allowed. At least 4 weeks must have elapsed from completion of the radiation therapy and all signs of toxicity must have resolved. Prior adjuvant chemotherapy is allowed if completed ≥6 months prior to the documentation of metastatic disease. Exclusion Criteria: Patients with known central nervous system (CNS) metastases may be enrolled, provided the metastases have undergone treatment, the patient is asymptomatic, and the patient does not require antiepileptic drugs or steroids as treatment for the CNS metastases. Patients with poorly controlled or clinically significant atherosclerotic vascular disease including New York Heart Association Grade 3 or greater congestive heart failure; unstable angina ; myocardial infarction, cardiovascular accident, transient ischemic accidents, angioplasty, cardiac or vascular stenting in the past 6 months; or ventricular arrhythmia requiring medication. Patients with previously diagnosed symptomatic bradycardia will be ineligible. Medical history of prolonged QT syndrome (>450 ms). Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, or psychiatric illness/social situations that would limit safety or compliance with study requirements. History of hypersensitivity to active or inactive excipients of any component of treatment (5-FU, leucovorin, oxaliplatin, or Tivantinib), or known dipyrimidine dehydrogenase deficiency. Patients with evidence of bleeding diathesis or significant coagulopathy (in the absence of therapeutic anticoagulation). Significant vascular disease (e.g., aortic aneurysm requiring surgical repair, or recent peripheral arterial thrombosis) ≤6 months prior to Day 1 of treatment. Any known positive test for human immunodeficiency virus, hepatitis C virus or acute or chronic hepatitis B infection. Mental condition that would prevent patient comprehension of the nature of, and risk associated with, the study. Use of any non-approved or investigational agent ≤28 days or 5 half-lives prior to administration of the first dose of study drug, whichever is shorter. Patients may not receive any other investigational or anti-cancer treatments while participating in this study. Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter drug absorption (e.g. active inflammatory bowel disease, uncontrolled nausea, vomiting, diarrhea, or malabsorption syndrome). Inability to swallow whole capsules. PHASE I ONLY •Patients who have had radiation therapy, hormonal therapy, biologic therapy, investigational agents, or chemotherapy for cancer within 28 days or 5 half-lives of the chemotherapy or biologic/targeted agents, whichever is shorter, prior to Day 1 of the study. PHASE II ONLY •Past or current history of neoplasm other than the entry diagnosis with the exception of treated non-melanoma skin cancer or carcinoma in situ of the cervix, or other cancers cured by local therapy alone and a disease free survival ≥5 years.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Incidence of Dose Limiting Toxicities (DLT) in Phase I Dose Escalation | Using a standard 3+3 design participants were enrolled in dose-escalating cohorts to determine the maximum tolerated dose (MTD) of tivantinib when given with FOLFOX (5-FU 400 mg/m^2, continuous IV 5-FU 2400 mg/m^2 over 46 hours, leucovorin 400 mg/m^2 IV, and oxaliplatin 85 mg/m^2). MTD is defined as the highest dose level at which no more than 1 of 6 patients experiences a DLT, assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v4. | 14 Days (1 cycle) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression Free Survival in Phase II Dose Expansion | Defined as the time from first treatment until objective tumor progression or death from any cause. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. | every 8 weeks until treatment discontinuation, projected 18 months and then every 3 months thereafter up to 5 years from start of treatment. | 
| Overall Survival in Phase II Dose Expansion | Defined as the time from first treatment until death from any cause. | every 8 weeks until treatment discontinuation, an expected average of 18 months, then every 12 weeks thereafter up to 5 years from start of treatment. | 
| Time to Progression in Phase II Dose Expansion | Defined as the time from first treatment until objective tumor progression. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions. | every 8 weeks until progressive disease, expected 18 months. |
