Abstract 1157O

Background

Immune checkpoint blockade (ICB) has demonstrated limited activity in advanced NENs mainly due to the background biology of these “cold” neoplasms, with low tumor mutational burden, expression of PD-L1 and lymphocyte infiltration. Targeting both PD-L1 and CTLA-4 may increase the efficacy of ICB in NENs and revert the intrinsic resistance to this therapeutic approach.

Methods

Pts were recruited in four cohorts (C1-4): typical/atypical lung carcinoids (C1), G1/2 gastrointestinal (C2), G1/2 pancreatic (C3) and G3 NENs of gastroenteropancreatic origin (C4). All pts were included after progression to standard therapies for each C. Pts received durvalumab (D) 1500 mg up to 13 cycles and tremelimumab (T) 75 mg up to 4 cycles, every 4 weeks. Primary objective was 9-month (m) clinical benefit rate (CBR) for C1-3 and 9-m overall survival rate (OS) for C4. Assuming a 9mCBR P0/1 of 30%/50% for C1-3, and 9mOS P0/1 of 13%/23% for C4, (α=0,05 and 80% power) 28 pts in C1-3 and 30 pts in C4 were needed.

Results

123 pts were included. Median age 62-y, 59% male, 43% ECOG 0. With a median follow-up of 10.8 m, CBR at 9-m was 7.4%/32.3%/25% for C1/2/3 respectively. OS rate at 9-m for C4 was 36.1%. The irRECIST overall response rates (irORR) for C1-4 were 7.4%/0%/6.3%/9.1%, respectively. PD-L1 expression did not enrich for efficacy in either primary or secondary endpoints except for C1 group, where irORR was 16% in pts with PD-L1-positive tumors vs. 0% in pts with PD-L1 negative (p=0.033). Most common treatment-related AEs were fatigue (43%), diarrhea (31.7%), pruritus (23.6%), nausea (13.8%), and hypothyroidism (9.8%). Most frequent grade ≥3 treatment-related AEs were liver toxicity (9.7%), diarrhea (6.5%), fatigue and vomiting (2.4% each).

Conclusions

D+T combination showed modest activity in this heavily pretreated population. In high grade NENs, D+T reached the primary endpoint of increasing OS rate and deserves further evaluation. Objective radiological responses were infrequent. No new safety concerns have been observed in this large population of advanced NENs.
