Abstract:
6032 Background: In the randomized phase III Study CA209141, Nivolumab (N) demonstrated significant overall survival (OS) benefit with favorable safety profile for platinum refractory R/M SCCHN and is now approved for these patients (pts). The objectives of the study are to provide additional insight into the frequency of high-grade AEs related to N and the efficacy of N in real life. Methods: Between August and December 2017, 203 pts were included in the multicenter, non-controlled phase II TOPNIVO. The main inclusion criteria were patients with platinum refractory R/M SCCHN with progressive disease, ECOG 0-2. Pts received N 3mg/kg every 2 weeks intravenously over 30 minutes. Four pts did not receive N. We report here the safety during the first 6 months (mo) after inclusion and OS results on the first 199 treated pts. Results: Median age was 62 yr, 83% were male, 84% were ECOG 0-1, 16% 2. The primary site of cancer was oral cavity 26%, oropharynx 38%, larynx 16%, hypopharynx 21%. 33% had loco regional relapse, 32% metastatic disease and 35% both. 49% had received one prior line of chemotherapy and 30% two prior lines. 157 (79%) pts ended their treatment within the first six mo: 5 for AE related to N (pneumonitis 3 pts, hepatitis 1 pt, diarrhea 1 pt), 107 for progression, 33 for death (24 related to progression, 9 to intercurrent disease), 12 other. 132 pts (66%) experienced at least 1 AE grade ≥3. On the 226 AEs grade 3-4, 21 (mainly pneumopathy, lipase increase and asthenia) were related to N and occurred in 18 pts. On the 51 AEs grade 5, 3 were considered related to N (2 pneumonitis, 1 cardiac arrest). The median OS was 7.7 mo (CI 95% [6.0; 9.5]) in the whole population; 9.2 mo [6.8; 12.1] in the 167 pts with ECOG 0-1, 3.0 mo [1.1; 6.0] in the 32 pts with ECOG 2; 12.1 mo [7.6; NR] in the 64 pts with metastatic disease, 7.7 mo [5.0; 9.6] in the 66 pts with locoregional disease and 4.6 mo [3.1; 7.9] in the 69 pts with both. OS was similar in pts older or younger 70 yr. Conclusions: The interim analysis of the TOPNIVO study shows no additional toxicities of N compared to what has been described previously, confirms the previous results of OS and provides new survival data in subgroups of pts.
