Abstract 1600
Background
Nivolumab (N), an IgG4 monoclonal antibody to PD-1, yields long-term disease control and prolonged survival in some patients (pts) with HCC, leading to its approval by the FDA in 2017 as 2nd line therapy after sorafenib. We present our institutional experience with N in the treatment of HCC at Mount Sinai Hospital.
Methods
Medical records of HCC pts treated with N until progression or intolerable toxicity between June 2016 and July 2018, were reviewed. Response was evaluated by RECIST 1.1. Overall and Progression free survival (OS, PFS) were estimated by Kaplan-Meier method.
Results
104 pts (84% male, median age 66 [29-89] years) were identified. 24 (23%) pts were Asian, 26(25%) Black, 30(29%) White and 24(23%) unknown. Hep C was the most common risk factor in 50 (48%) pts, followed by Hep B in 34(32%) with co-infection in 7 (6%) pts, NASH in 10 (9%), Alcohol in 8(7%) and other including HIV in 10 (9%)pts. Cirrhosis was present in 83 (80%) pts. Child Pugh score (N = 96) and was A in 64 (67%) and B in 32 (33%) pts. Barcelona Clinic Liver Cancer (BCLC) stage was B in 21 (20%) and C in 83 (80%) pts. 67 (64%) pts received 1st line systemic therapy with N. Among the 37 (36%) treated with N in subsequent lines, 27 (73%) had progressed on Sorafenib. Loco-regional therapies (LRT) including Y90 and TACE were given concurrently with N in 32(31%) pts. The median duration of treatment was 26 (2-149) weeks and median follow up was 17 months (95% CI (15.7, 20.7)). Objective response rate was 20% including 10(10%) complete responders (CR), all of whom received concurrent LRT. 39(37%) pts had progressive disease (PD) and 40(38%) had stable disease (SD). Median duration of response was 9 (1-31) months. Median OS and PFS are shown in the table.Table:
759P
OS (months) | P | PFS(months) | P | |
---|---|---|---|---|
By line: | ||||
First | 23 | 0.1013 | 16 | 0.1394 |
Subsequent | 12 | 6 | ||
By response: | ||||

PD | 7 |
Conclusions
HCC pts treated at our institution frequently received N in first line and 31% received concurrent LRT. Survival did not differ statistically between first vs subsequent line N. Our real-world experience with N in HCC appears comparable to data from the checkmate-040 study.
