This study will assess the safety and efficacy of Single Tremelimumab Regular Interval Durvalumab (STRIDE) as first-line therapy in participants with advanced unresectable HCC.

Condition or disease Intervention/treatment Phase
Advanced Hepatocellular Carcinoma Drug: Durvalumab Drug: Tremelimumab Phase 3

Detailed Description:

This is a Phase IIIb, open-label, single arm, multicentre study to assess the safety and efficacy of STRIDE as first-line therapy in participants with advanced unresectable HCC who have one of the following:

  1. Child-Pugh score B7 or B8 with a World Health Organisation Eastern Cooperative Oncology Group Performance Status (WHO/ECOG PS) of 0-1 at enrolment, or
  2. Child-Pugh class A with a WHO/ECOG PS of 2 at enrolment, or
  3. Child-Pugh class A with a WHO/ECOG PS of 0-1 and with evidence of chronic main trunk portal vein thrombosis at enrolment

Participants must not have received any prior systemic therapy for HCC. Participants may have previously received locoregional therapy (LRT) but must no longer be suitable for additional LRT. Any local treatment needs to have been completed at least 4 weeks prior to initiation of treatment. The study consists of 4 periods: screening (Day-28 to Day -1), Treatment period, safety follow-up and survival follow-up.

The QLQ-HCC18 is an HCC-specific module from the EORTC comprising 18 questions to assess HCC symptoms. The module includes 6 multi-item domain scales and 2 single-item scales. Final scores range from 0 to 100 where higher scores indicate a greater level of symptom severity and a poorer HRQoL. The items prioritized are single items shoulder pain, abdominal pain and abdominal swelling.

  13. Clinically meaningful change from baseline in HRQoL as assessed by EORTC QLQ-HCC18 [ Time Frame: Every 8 weeks from date of first dose of IMP for the first 48 weeks and then every 12 weeks thereafter until treatment discontinuation and 90 days after last dose during safety follow-up [approx. up to 33 months] ]
