Abstract 1061P
Background
Cemiplimab is a programmed cell death receptor-1 inhibitor with antitumour activity for cutaneous squamous cell carcinoma (CSCC) and acceptable safety proved in its pivotal trial. We provide the first data on cemiplimab safety in daily practice from the named patient programme (NPP) for advanced CSCC in Spain.
Methods
This cemiplimab NPP was performed from March 2019 to March 2020. It included patients aged ≥18 years with advanced CSCC and ineligible for surgery, radiation therapy or clinical trials. The cemiplimab safety was assessed according to treatment-emergent adverse events (TEAEs) reported until March 2021.
Results
140 patients were included (median age [interquartile range, IQR] 77.0 [65.0-84.0] years; age ≥80 38%; men 71.7%; ≥1 comorbidity 83%; ECOG 0-1 86.3%; locally advanced CSCC 60.7%; cemiplimab as first-line therapy 67.7%). Cemiplimab was received for a median (IQR) of 8.0 (3.0-14.0) cycles. Fifty-eight (41.4%) patients showed ≥1 of the 163 TEAEs reported, which most frequently included diarrhoea n=7, asthenia n=6, constipation n=4 and abdominal pain n=4. Fourteen (8.6%) were immune-mediated, mainly bronchitis n=2, pneumonitis n=2 and hepatitis n=2. Seventy-eight (47.9%) TEAEs were grade ≥3, most frequently pneumonia n=3, COVID-19 n=3, general physical health deterioration n=2, pyrexia n=2, renal transplant failure n=2, sepsis n=2, acute kidney injury n=2 and respiratory failure n=2. Twenty-one (12.9%) were treatment-related (TREAEs): 11 (6.7%) were grade 1-2 (diarrhoea n=3 and asthenia, hepatotoxicity, malnutrition, odynophagia, polymyalgia rheumatica, pneumonitis, pruritus, and skin toxicity), 9 (5.5%) grade 3 (acute kidney injury, adrenal insufficiency, abdominal pain, blood creatinine increased, dysphagia, haematuria, immune-mediated enterocolitis, panniculitis, surgical wound infection) and 1 (0.6%) unknown grade. Cemiplimab was withdrawn due to TREAEs in only 5 (3.6%) patients. The TEAE outcome was fatal in 29 (17.8%); none related to cemiplimab.
Conclusions
This NPP supports the real-life safety of cemiplimab for CSCC, showing an acceptable safety profile consistent with previous reports.
