Overview

This study aims to evaluate the response to immunotherapy in HCC, assess the toxicity profile and measure overall survival within the study period. The primary end point is evaluation of progression free survival in HCC patients receiving immunotherapy. The secondary end point is to assess overall survival within the study period, duration of response and the response rate. The tertiary end point is to assess the toxicity profile.

Treatment starts after MDT discussion and approval for diagnosis, staging and treatment protocol. * This study includes patients with advanced HCC who will receive their first line of treatment. Cases will receive atezolizumab (1200 mg) + bevacizumab (15mg/kg) every 3 weeks or Tremilimumab (300 mg single dose IV infusion on first day only) + Durvalumab (1500 mg on the same day then every 4 weeks) according to eligibility criteria. * Cases will be evaluated every cycle clinically and laboratory. * Baseline investigations will include; 1. Laboratory ; 1. CBC 2. liver enzymes (ALT, AST, alkaline phosphatase, GGT) 3. liver function tests (serum albumin, serum bilirubin total and direct, INR) 4. kidney function tests (serum creatinine, BUN, 24 hrs urinary protein) 5. electrolytes Na, K, Ca) t) Others; HBAlc, Thyroid function tests (TSH, T3, T4), Alpha feto protein 2. Radiological imagings; 1. Triphasic CT and/or dynamic MRI abdomen 2. PET scan or CT chest and bone scan 3. ECG, ECHO, Upper GI endoscopy * Every 3 months patients will undergo laboratory and radiological investigations, assessed by 2 blinded radiologists. * The degree of adverse events was evaluated according to The Common Terminology Criteria for Adverse Events version 5.0.(30) ,which rates toxicity on a scale from 1 to 5, with ascending order of severity. This will be managed according to toxicity grade whether treatment interruption, dose reduction or discontinuation. * Study treatment to be continued until disease progression, unacceptable toxicity, serious inter-current illness, patient request for discontinuation, or need for any other anticancer agent other than study treatment.

Outcomes

Primary Outcomes

Progression free survival in HCC patients receiving immunotherapy.

Progression-free survival (PFS) is defined as the time elapsed between treatment initiation and tumor progression or death from any cause. Progression (i.e., PD) was defined as presence of new measurable/non- measurable lesions, or ≥ 20% increase in tumour burden relative to nadir

Time frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 months

Secondary Outcomes

overall survival within the study period,

Overall survival (OS) is defined as time from diagnosis to either last follow-up or /death

Time frame: From date of randomization until the date of loss of follow up or date of death from any cause, whichever came first, assessed up to 12 months

Response rate

Response rate is defined as the proportion of patients with a complete response/immune complete response or partial response/ immune partial response to treatment

Time frame: From enrollment to study till 1 year or treatment
