| アブストラクト | OBJECTIVE: Real-world studies on the safety of camrelizumab are scarce. This study aimed to investigate the adverse drug reactions (ADRs) associated with camrelizumab and evaluate their clinical characteristics and management. METHODS: We retrieved data on ADRs related to the PD-1 inhibitor camrelizumab from the World Health Organization (WHO) adverse event reporting system database (VigiAccess) for the period from June,2019 to July 2025. Additionally, we conducted a retrospective analysis of case reports and case series on camrelizumab-related ADRs published from 2019 to 2025. RESULTS: 601 ADR reports were included in the VigiAccess database. Asian patients accounted for 99% (597/601), and the majority were male (69%). The most common classification of systemic organs (SOC) is hematological disorders (21.8%), skin reactions (14.3%), and systemic symptoms (8.8%). The main adverse reactions were: Hematological system: bone marrow suppression (10.3%), thrombocytopenia (5.1%); Skin: rash (5.7%), pruritus (4.3%), reactive capillary hyperplasia (RCCEP); systemic: fever (2.6%), chest pain (2.1%); serious events: myocarditis (1.2%), toxic epidermal necrolysis (TEN). Literature analysis included 80 patients (from China), with a median age of 60 years (range 20-84), and 72.5% were male. The main indications are non-small cell lung cancer (20%), nasopharyngeal carcinoma (20%) and hepatocellular carcinoma (11.3%). The median occurrence time of adverse reactions was 8 weeks (ranging from 10 minutes to 88 weeks). Typical ADRs include: cutaneous toxicity (45 cases, 56.3%); RCCEP (32 cases), Stevens-Johnson (SJS)/TEN (5 cases); hematological toxicity (38 cases, 47.5%): bone marrow suppression (22 cases), thrombocytopenia (16 cases); cardiotoxicity (13 cases, 16.25%), mainly myocarditis; Others: immune hepatitis (6 cases), thyroid dysfunction (5 cases). CONCLUSION: The ADRs of camrelizumab are primarily hematologic and skin toxicities, with a need to be vigilant for late-onset serious events (e.g., myocarditis, TEN). Early identification and corticosteroid intervention are key management strategies. |
