A Safety and Efficacy Study of CC-122 in Combination With Nivolumab in Subjects With Unresectable Hepatocellular Carcinoma (HCC)

Carcinoma, Hepatocellular Clinical Trial

Official title: A Phase 1/2, MultiCenter, Open-label, Dose Finding Study to Assess the Safety, Tolerability and Preliminary Efficacy of CC-122 in Combination With Nivolumab in Subjects With Unresectable Hepatocellullar Carcinoma (HCC) Following First Line Treatment Failure

Status Completed

Clinical Trial Summary

CC-122-HCC-002 is a Phase 1/2 dose escalation and expansion clinical study of CC-122 in combination with nivolumab in subjects with unresectable hepatocellular carcinoma (HCC) who have progressed after or were intolerant to no more than 2 previous systemic therapies for unresectable HCC, or are naïve to systemic therapy.

Clinical Trial Description

Study population included subjects who had progressed after or were intolerant to no more than 2 previous systemic therapies for unresectable HCC, or are naïve to systemic therapy. The dose escalation part of the study was designed to explore three dose levels of CC-122 to identify the recommended phase 2 dose (RP2D) to be used in the expansion phase. Approximately 20 subjects were to be enrolled in the dose escalation part of the study. Subjects could be treated for up to 2 years, or until progression of disease, unacceptable toxicity, subject/physician decision, withdrawal of consent, death. Safety follow up until 28 days after CC122 treatment and 90 days after nivolumab treatment. RECIST 1.1 criteria was used to determine response. Survival follow up until death, withdrawal of consent, or the study closes. Subjects were permitted to continue treatment beyond progression (TBP) if they continue to meet protocol criteria, had stable performance status, had clinical benefit, other treatment options were discussed. A separate ICF was signed to continue TBP. During the dose escalation phase, CC-122 was administered orally 5 consecutive days out of 7 (5 days on/2 days off weekly) on Days 1 to 5, 8 to 12, 15 to 19 and 22 to 26 of each 28-day cycle. Once the RP2D for dosing of CC-122 in combination with nivolumab was defined, expansion (Phase 2) would start. A modified 3+3 dose escalation design was used to identify the initial toxicity of the combination. Up to six subjects were concurrently enrolled into a dose level. Decisions as to which dose level to enroll a new subject were based on the number of subjects enrolled and evaluable, the number of subjects experiencing DLTs, and the number of subjects enrolled but who are not yet evaluable for toxicity in the current cohort at the time of new subject entry. A Safety Review Committee (SRC) comprised of investigators participating in the study made dose escalation decisions based on these criteria. After completion of the Dose Escalation Phase, the Dose Expansion Phase of the study did not proceed due to the changing landscape in the treatment of HCC. There were no additional safety concerns or safety signals identified in the dose escalation phase of the study. ;
