Patients were randomly assigned to receive either nivolumab 1 mg/kg as an IV infusion with ipilimumab 3 mg/kg IV every 3 weeks for a maximum of 4 doses, followed by single-agent nivolumab 480 mg IV every 4 weeks (n = 335), or the investigator’s choice of lenvatinib or sorafenib (n = 333). The primary end point was OS, which was measured up to 4 years, and secondary end points were objective response rate (ORR), duration of response, and time to symptom deterioration, which were also assessed up to 4 years.1,2,5
The median OS was about 23.7 months (95% CI: 18.8, 29.4) in the nivolumab plus ipilimumab arm and 20.6 months (95% CI: 17.5, 22.5) in the lenvatinib or sorafenib arm (HR 0.79 [95% CI: 0.65, 0.96]; p < .0180) at a median follow-up of 35.2 months, according to results published in the Journal of Clinical Oncology. Additionally, the nivolumab and ipilimumab regimen also demonstrated a favorable ORR (36.1% [95% CI: 31.0, 41.5]) when compared with standard of care (13.2% [95% CI: 9.8, 17.3]; p < .0001).1,5
About the Trial
Trial Name: A Study of Nivolumab in Combination With Ipilimumab in Participants With Advanced Hepatocellular Carcinoma (CheckMate 9DW)
ClinicalTrials.gov ID: NCT04039607
Sponsor: Bristol-Myers Squibb
Completion Date (Estimated): September 30, 2026
Further, the data also showed 24-month OS rates of 49% (95% CI: 44, 55) and 39% (95% CI: 34, 45) in the nivolumab plus ipilimumab and standard of care groups, respectively. In these respective groups, median DOR was about 30.4 months and 12.9 months, with complete response observed in 7% and 2% of patients.5
The most common adverse events (AE; >20%) were rash, pruritus, fatigue, and diarrhea, according to the FDA news release.1 Grade 3 and 4 treatment-emergent AEs were observed in 137 (41%) of patients receiving nivolumab and ipilimumab and 138 (42%) of patients receiving standard of care. Additionally, these led to the discontinuation of treatment in 44 (13%) and 21 (6%) of patients in these respective groups.5
