Phase 1 Study of SF1126 in Combination With Nivolumab in Patients With Advanced Hepatocellular Carcinoma

A Phase I Study of SF1126, a Dual PI3 Kinase and Bromodomain Inhibitor, in Combination With Nivolumab in Patients With Advanced or Metastatic Hepatocellular Carcinoma and Child-Pugh A-B7 Cirrhosis

Summary

Primary Objectives: 1. To determine the maximum tolerated dose (MTD) or maximum recommended dose of SF1126 in combination with nivolumab in adult patients with advanced (unresectable or metastatic) HCC and Child-Pugh A or Child-Pugh B7 cirrhosis. 2. To determine the recommended phase II dose of SF1126 in combination with nivolumab in patients with advanced (unresectable or metastatic) HCC and Child-Pugh A or Child-Pugh B7 cirrhosis. Secondary Objectives: 1. To describe the safety and tolerability of SF1126 in adult patients with underlying liver disease by ongoing evaluation of adverse events. 2. To determine pharmacokinetics in HCC patients. 3. To assess the effect of SF1126 in combination with nivolumab on progression-free survival and overall survival. Primary Endpoint: The primary endpoint is the rate of dose limiting toxicities (DLTs) at within 56 days of starting treatment, and the maximum tolerated dose or maximum recommended dose of SF1126 in combination with nivolumab. Secondary Endpoints: 1. Adverse events related to SF1126 (description, timing, grade \[CTCAE v4.03\], severity, seriousness, and relatedness). 2. Pharmacokinetics in HCC patients. 3. The proportion of patients remaining progression-free by radiographic criteria as assessed by RESIST v1.1 at 4 months, and, as available, median progression-free survival and overall survival estimated using the Kaplan-Meier method.

Detailed description

SF1126 is a dual inhibitor of phosphatidylinositol-3-kinase (pan-isoform specific) and bromodomain-containing protein 4 (BRD4) which simultaneously disrupts two key MYC-mediating factors that promote cancer cell growth. Nivolumab is a humanized, IgG4 isotype monoclonal antibody that binds to PD-1 and blocks binding of PD-1 to its ligands PD-L1 and PD-L2. Nivolumab monotherapy is approved in the US for HCC previously treated with sorafenib. Funding source: FDA OOPD

Interventions

Type	Name	Description
DRUG	SF1126	SF1126 is a dual PI3 kinase/BRD4 inhibitor small molecule. It will be administered IV twice weekly (900 mg/m2 starting dose with escalation to 1000 mg/m2 per dose and 1100 mg/m2 per dose) at a dose determined by the cohort the patient is enrolled in until progression or unacceptable toxicity develops.
DRUG	Nivolumab	Nivolumab is a humanized, IgG4 isotype monoclonal antibody that binds to PD-1 and blocks binding of PD-1 to its ligands PD-L1 and PD-L2. It will be administered at 240 mg IV every 2 weeks until progression or unacceptable toxicity develops.
