Abstract 2085


Recurrent and metastatic (R/M) SCCHN outcomes are generally poor and new treatments are needed. An ongoing phase I/II, multicenter, open-label study (NCT01693562) is evaluating the safety and efficacy of durvalumab (D), a human lgG1 mAb that blocks PD-L1 binding to PD-1 with high affinity and selectivity, in multiple solid tumor types including SCCHN. PD-L1 is expressed in SCCHN tumors and is associated with response to anti-PD-L1 treatment.


Pts with R/M SCCHN, an ECOG of 0 or 1, and no prior anti-PD-1/PD-L1 exposure are eligible. D is given every 2 weeks IV at 10 mg/kg for 12 months. Retreatment is permitted upon progression after 12 months. Safety data and efficacy data (DoR and PFS/OS) included have more mature follow up than previously reported (Segal, N et al. Poster presented at ASCO 2015, 3011).


As of 29 Apr 2016, 62 pts (mean age 58 years [range 24-96]; 86% male; 63% current/prior smokers; ECOG 0/1: 38%/62%; HPV pos/neg/unk: (40.3%/40.3%/19.4%), PD-L1 pos/neg/unk: (34%/61%/5%), had received a median of 3 prior systemic treatments (1-13)). Median duration of follow-up was 25.0 (range 1.4 – 31.6) months. The most frequent drug-related AEs were fatigue (18%), diarrhea, (8%), and nausea (8%). Five pts (8%) had AEs ≥Gr3 and there were no drug-related AEs leading to death. Among seven responders, six patients had DoR for >= 12 months with longest DoR being 19.8 months. Six and 12-month OS is 62% (95% CI 48, 74) and 42% (95% CI 27, 55), respectively. Preliminary analysis revealed no clear difference in OS by PD-L1 status.


In this updated report, the safety profile of D in SCCHN is consistent with previous reports. Responses are durable; landmark OS rates are encouraging in this heavily pre-treated population. A registration program is underway in pts with SCCHN for D alone and in combination with tremelimumab.
