Introduction

• Nivolumab monotherapy is approved in several countries for sorafenib-treated patients with HCC based on

data from the CheckMate 040 study (NCT01658878), which reported an ORR of 14% and median OS of 15

months1

• The clinical efficacy observed with nivolumab monotherapy has led to investigation of nivolumab combination

therapy to achieve durable responses in higher proportions of patients

• The combination of nivolumab, a PD-1 checkpoint inhibitor, and ipilimumab, a CTLA-4 immune checkpoint

inhibitor, promotes synergistic antitumor immune response using distinct but complementary mechanisms2

and has shown durable responses in other tumor types (RCC, NSCLC, melanoma, and MSI-H/dMMR CRC)3-6

• The first report on the combination of nivolumab plus ipilimumab in sorafenib-treated patients with advanced

HCC indicated that the combination led to robust and durable responses in sorafenib-treated patients7

• Here we report results for the nivolumab plus ipilimumab combination in sorafenib-treated patients with

advanced HCC, with a focus on hepatic safety

CTLA-4, cytotoxic T-lymphocyte–associated protein 4; HCC, hepatocellular carcinoma; MSI-H/dMMR CRC, microsatellite instability–high/DNA mismatch repair–deficient metastatic

• The vast majority of select TRAEs resolved, with the exception of endocrine events; across all treatment arms, ≈90% of hepatic

select TRAEs resolved

aTime to onset measured from treatment initiation and time to resolution measured from select TRAE onset; bIn arm A, 4 patients had hypersensitivity/infusion reactions; all

events resolved (median TTO: 10.3 weeks [range: 0.1–21.1]; median TTR: 0.4 week [range: 0.1–9.1]); cIn arm B, 1 patient had a renal select TRAE (TTO: 15.0 weeks;

Conclusions

• The combination of nivolumab plus ipilimumab led to clinically meaningful responses in sorafenib-

treated patients, with ORR > 30% in each treatment arm

– Patients in arm A had a median OS of 22.8 months and the highest OS rate of 44% through 30 months

• Nivolumab plus ipilimumab had a manageable safety profile in this patient population with advanced

HCC

– No new safety signals were seen with the addition of ipilimumab in any treatment arms

– The safety profile of nivolumab plus ipilimumab in HCC was consistent with that observed in studies of other

tumor types1-5

– Higher rates of TRAEs, IMAEs, and discontinuation due to study drug toxicity were observed in arm A

compared with arms B and C, with similar rates of AEs observed in arms B and C

– The majority of select TRAEs resolved across treatment arms with steroid use; ≈90% of patients in each arm

had resolution of hepatic select TRAEs

• The favorable benefit/risk profile observed with nivolumab plus ipilimumab warrants further

investigation

– The CheckMate 9DW phase 3 study of this combination in patients with HCC is planned (NCT04039607)1. Hellmann MD, et al. Lancet Oncol 2017;18:31–41; 2. Hodi FS, et al. Lancet Oncol 2016;17:1558–1568; 3. Motzer RJ, et al. N Engl J Med 2018;378:1277–1290; 4. Hammers HJ, et al.
