Study of Tremelimumab and Durvalumab (MEDI4736) (T300+D) in Advanced Hepatocellular Carcinomas With Child-Pugh-B Cirrhosis

Phase II Single Arm Study of Tremelimumab and Durvalumab (MEDI4736) (T300+D) in Advanced Hepatocellular Carcinomas With Child-Pugh-B Cirrhosis (STRIDE in CP-B)

This is a single-arm, phase II study of patients with advanced liver cancer or hepatocellular carcinoma (HCC) who are eligible for first-line treatment with T300+D. The invesitgators hypothesize that T300+D will be safe and tolerated in CP-B patients with HCC. HCC mostly affects disadvantaged populations with higher rates among racial/ethnic minorities, who are often not included in clinical trials (i.e., Hispanics, Blacks, underserved, low socioeconomic status) and present with more severe disease. Given there is not much data in the US patient cohort, this study provides a chance to gain that knowledge.

Study Overview

• Status: Recruiting
• Conditions: Hepatocellular Carcinoma; Cirrhosis, Liver
• Intervention / Treatment: Drug: Tremelimumab; Drug: Durvalumab

Detailed Description

Priming dose of tremelimumab 300 mg IV once (Cycle 1, Day 1 only) with durvalumab 1500 mg IV on Day 1 of each 4-week cycle. Patients will stay on study treatment until evidence of disease progression, unacceptable toxicity, or death.

All eligible patients who consent to this study must have a baseline evaluation (CT or MRI) within 28 days of the start of treatment.

Follow-up: A repeat CT/MRI scan will be performed after 2 cycles of treatment regimen to evaluate response based on RECIST 1.1 criteria (See Appendix for definitions of response).12 Serum tumor marker AFP (every cycle) and CT/MRI scans will be repeated at least every 2 cycles, or 8 weeks, to ensure no progression of disease. Patients will continue treatment until disease progression, unacceptable toxicity, withdrawal of consent by the patient, or decision of physician for patient's best interest. Each patient will be followed for survival for up to one year.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Grade 3 or Higher Treatment Related Treatment Emergent-Adverse Events (TRTE-AEs)	The number and grade 1-5 of all adverse events will be documented according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0; measured at baseline, each cycle, and up to 90 days after treatment discontinued. Grade 3 and higher TRTE-AEs will be reported for this outcome.	Baseline up to 1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Objective Response Rate (ORR)	ORR, complete and partial response, confirmed and unconfirmed as defined by Response evaluation criteria in solid tumors (RECIST) v1.1.9. ORR, complete and partial response, confirmed and unconfirmed) as defined by RECIST v1.1.9. RECIST version 1.1 RECIST is used as tumor response criteria in most trials of solid tumors in general. RECIST1. 1 uses unidimensional diameters of target lesions and the sum of measurements of all target lesions as a quantitative measure of tumor burden.	Baseline to 1 year
Progression Free Survival (PFS)	Measured from the date of registration until disease progression, symptomatic deterioration, or death.	Baseline to 1 year
Overall Survival (OS)	Measured from date of registration until death	Baseline to 1 year
Albumin-Bilirubin (ALBI) grade	Albumin-bilirubin (ALBI) grade is a tool that assesses liver function by combining serum albumin and bilirubin levels. It can be used to predict the prognosis of patients with liver cirrhosis and hepatocellular carcinoma, and has been shown to be more accurate than the Child-Pugh score. ALBI grade can also be used to predict survival for patients treated with radioembolization (RE), and as a prognostic indicator for cancer patients receiving chemotherapy. A calculator is used to generate the score. Based on the score, patients are graded between grade 1 (lowest mortality risk, ALBI score ≤2.60) and grade 3 the highest mortality risk (score >-1.39).	Baseline to 1 year

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
European Organisation For Research and Treatment of Cancer (EORTC)- Quality of Life Questionnaire (QLC)	A 30-item self-administered questionnaire with 9 multiple-item scales: 5 scales that assess aspects of functioning (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, and nausea/vomiting), and a global measure of health status/QOL scale. There are 5 single-item measures assessing additional symptoms commonly reported by cancer patients (dyspnea, loss of appetite, insomnia, constipation, and diarrhea) and 1 item concerning the perceived financial impact of the disease. All but 2 questions have 4-point scales: "Not at all," "A little," "Quite a bit," and "Very much". The 2 questions concerning global health status and QOL have 7-point scales with ratings ranging from "Very poor" to "Excellent". For each of the 15 domains (9 multiple item scales and 6 single-item scales), final scores are transformed such that they range from 0 to 100, where higher scores indicate greater functioning, greater health related quality of life, or lower level of symptoms.	Baseline up to 16 weeks
EORTC QLQ-HCC18 (18-item hepatocellular cancer health-related quality of life questionnaire)	The EORTC QLQ-HCC18 module is an 18-item self-administered questionnaire (Appendix) developed and validated specifically for HCC). There are 5 multiple-item symptom scales (fatigue [3 items], jaundice [2 items], nutrition [5 items], pain [2 items], and fever [2 items]); 2 single-item symptom scales (abdominal swelling and sexual interest); and 1 multiple-item functional scale (body image [2 items]). All questions have a 4-point scale: "Not at all," "A little," "Quite a bit," and "Very much". For each of the 8 domains (6 multiple-item scales and 2 single-item scales), final scores are transformed such that they range from 0 to 100, where higher scores indicate greater level of symptoms. All item response scores are converted into 0 to 100 scores; for all scales, a higher score means a worse symptom or a poorer health related quality of life.	Baseline to 16 weeks
