A Study Evaluating The Efficacy and Safety of Neoadjuvant Immunotherapy Combinations in Patients With Surgically Resectable Hepatocellular Carcinoma

Phase 1
Active, not recruiting
Conditions
Carcinoma, Hepatocellular
Interventions
Registration Number
NCT05908786
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This is a Phase Ib/II, open-label, multicenter, randomized platform study to evaluate neoadjuvant immunotherapy combinations in participants with resectable HCC. The study is designed with the flexibility to open new treatment arms as new agents become available, close existing treatment arms that demonstrate minimal clinical activity or unacceptable toxicity, or modify the participant population.

Primary Outcome Measures
NameTimeMethod
Major Pathologic Response (MPR) RateAt the time of surgery

MPR rate is defined as the proportion of participants with =\<10% residual viable tumor in the tumor bed at the time of surgery, as assessed by central pathological review.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)Randomization to death from any cause (up to approximately 3 years)

OS is defined as the time from randomization to death from any cause.

Pathologic Complete Response (pCR) RateAt the time of surgery

pCR rate is defined as the proportion of participants with an absence of residual tumor at the time of surgery, as assessed by central pathological review.

Proportion of Participants Downstaged to Within Milan CriteriaPrior to surgery

Proportion of participants downstaged to within Milan criteria (for participants beyond criteria at randomization). Within Milan criteria is defined as single tumor \<= 5 cm or 2 - 3 nodules all \<= 3 cm.

Post-Operative MortalityWithin 90 days after surgery

Post-operative mortality is defined as death within 90 days after surgery

Relapse-Free Survival (RFS)Surgery to the first documented recurrence of disease (up to approximately 2 years)

RFS is defined as the time from surgery to the first documented recurrence of disease (intrahepatic or extrahepatic) according to EASL and/or RECIST v1.1, or death from any cause.

OS Rate at 24 MonthsRandomization up to 24 months

OS rate at 24 months is defined as the proportion of participants who have not experience death from any cause at 24 months after randomization.

Percentage of Participants With Adverse EventsUp to approximately 3 years after first participant enrolled
R0 Resection RateAt the time of surgery

R0 resection rate (proportion of resected participants obtaining an R0 resection). R0 resection is defined as a microscopically margin-negative resection, in which no tumor (gross or microscopic) remains in the primary tumor bed.

Post-Operative Surgical Complication Rates According to The Clavien-Dindo Surgical ClassificationSurgery to treatment completion/discontinuation (up to approximately 2 years)

Post-operative surgical complication rates according to the Clavien-Dindo surgical classification. Clinically relevant complications are defined as Clavien-Dindo Grade \>= IIIa.

Event-Free Survival (EFS)Randomization up to approximately 3 years

EFS is defined as the time from randomization to any of the following events (whichever occurs first): disease progression that precludes surgery, as assessed by the investigator according RECIST v1.1; local regional, or distant disease recurrence as measured by EASL and/or RECIST v1.1; or death from any cause.

Objective Response Rate (ORR)Prior to surgery

ORR is defined as the proportion of participants with a radiographic Complete Response (CR) or Partial Response (PR) prior to surgery, as determined by the investigator according to RECIST v1.1 and HCC mRECIST. Responses will be assessed and determined according to RECIST v1.1 and HCC mRECIST but are not required to be confirmed by subsequent imaging assessments.

Proportion of Participants With Delayed or Canceled Surgery Due to Treatment-Related Adverse Events>28 days from surgical restaging visit, anticipated up to 56 days

Proportion of participants with delayed or canceled surgery due to treatment-related adverse events (defined as \> 28 days from surgical restaging visit).

OS Rate at 36 MonthsRandomization up to 36 months

OS rate at 36 months is defined as the proportion of participants who have not experience death from any cause at 36 months after randomization.
