Sorafenib Tosylate and Pembrolizumab in Treating Patients With Advanced or Metastatic Liver Cancer

A Phase Ib/ II Study of Sorafenib and Pembrolizumab in Advanced Hepatocellular Cancer (HCC)

This phase Ib/II trial studies how well sorafenib tosylate and pembrolizumab work in treating patients with liver cancer that has spread to other parts of the body. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Giving sorafenib tosylate and pembrolizumab may work better in treating patients with liver cancer.

Study Overview

• Status: Active, not recruiting
• Conditions: Advanced Adult Hepatocellular Carcinoma; Child-Pugh Class A; Stage III Hepatocellular Carcinoma; Stage IIIA Hepatocellular Carcinoma; Stage IIIB Hepatocellular Carcinoma; Stage IIIC Hepatocellular Carcinoma; Stage IV Hepatocellular Carcinoma; Stage IVA Hepatocellular Carcinoma; Stage IVB Hepatocellular Carcinoma
• Intervention / Treatment: Other: Laboratory Biomarker Analysis; Biological: Pembrolizumab; Drug: Sorafenib Tosylate

Detailed Description

PRIMARY OBJECTIVES:

I. To assess the overall response rate (ORR) related to the combination of sorafenib tosylate (sorafenib) + pembrolizumab in advanced hepatocellular carcinoma patients.

SECONDARY OBJECTIVES:

I. To assess time to tumor progression in patients who received the combination therapy of sorafenib + pembrolizumab compared to historical data on sorafenib only treatment in patients with advanced hepatocellular carcinoma.

TERTIARY OBJECTIVES:

I. To obtain data on changes in immune cell function and in the tumor microenvironment pre- and post-treatment to screen for potential biomarkers that may be able to predict clinical benefit.

- All patients will be followed for survival

OUTLINE:

Patients receive sorafenib tosylate orally (PO) twice daily (BID) on days -28 to -1 and 1-21. Patients also receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, every 3 months for up to 1 year, then every 6 months thereafter.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall response rate defined as partial or complete response per immune-related Response Evaluation Criteria in Solid Tumors	The response rate will be estimated as the binomial proportion of responders among evaluable patients, and supported by Jeffreys? 95% confidence interval.	Up to 6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall survival	Will be estimated using the Kaplan-Meier method.	From the date of study enrollment to the time of death from any cause, assessed up to 1 year
Time to tumor progression	Will be estimated using the Kaplan-Meier method. Statistics describing the time to event distributions will be obtained from Kaplan-Meier methods and proportional hazards models. Continuous variables will be summarized with commonly used statistics (mean, standard deviation, median, etc.), with subgroup associations tested using the Wilcoxon rank sum test. Categorical variables will be summarized in contingency tables, with associations of interest assessed using Fisher?s exact test.	From the date of study enrollment to the first observation of progressive disease, assessed up to 1 year

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in functional activity of effector T cells	Will be correlated with overall survival. Measurements for several immune parameters will be obtained before and after treatment. The effect of treatment will be quantified as the post/pre-treatment mean ratio of the (potentially log transformed) expression measurements. Primary and derived immune marker expression measurements will be summarized with common descriptive statistics (mean/standard deviation). Associations between the paired pre- and post-measurements will be described with scatterplots and dot plots.
