Clinical Trial Summary

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.

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 domains/scales of the EORTC QLQ-C30 prioritized include global health status/QoL, functioning (physical), multi-term symptom (fatigue) and single item symptoms (appetite loss and nausea). Final scores range from 0 to 100, where higher scores on the global measure of health status and functional scales indicate better health status/function, but higher scores on symptom scales represent greater symptom severity.

Final scores range from 0 to 100, where higher scores on the global measure of health status and functional scales indicate better health status/function, but higher scores on symptom scales represent greater symptom severity.	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]
Secondary	Change from baseline in HRQoL as assessed by EORTC QLQ C-30	Change from baseline of global health status/QoL, symptom and functioning scores to assess disease and treatment related symptoms and HRQoL. The domains/scales of the EORTC QLQ-C30 prioritized include global health status/QoL, functioning(physical), multi-term symptom (fatigue) and single item symptoms(appetite loss and nausea). Final scores range from 0 to 100, where higher scores on the global measure of health status and functional scales indicate better health status/function, but higher scores on symptom scales represent greater symptom severity.	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]
Secondary	Time to deterioration in HRQoL as assessed by EORTC QLQ-HCC18	Time to deterioration is defined as time from date of first dose of study intervention to the date of the first clinically meaningful deterioration (defined as an increase from baseline of at least 10 points for EORTC QLQ-HCC18) that is confirmed at a subsequent visit or death (by any cause) in the absence of a clinically meaningful deterioration. 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.	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]
Secondary	Clinically meaningful change from baseline in HRQoL as assessed by EORTC QLQ-HCC18	Clinically meaningful change from baseline (categorized as improvement, no change or deterioration) is defined as an absolute change in the score from baseline of = 10 for scales/items from QLQ-HCC18 to assess disease-related symptoms. The single items prioritized are shoulder pain, abdominal pain and abdominal swelling. The EORTC QLQ-HCC18 module is an 18-item questionnaire. 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 and worse symptom or a poorer HRQoL.	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]

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 and worse symptom or a poorer HRQoL.
