Abstract
PURPOSE: Phase IV clinical trials are required to evaluate the real-world safety and effectiveness of drugs. This study aimed to evaluate the safety and effectiveness of once-per-cycle administration of PegaGen® (pegfilgrastim, CinnaGen, Iran) in cancer patients. METHODS: In this open-label, multicenter, prospective, real-world, post-marketing surveillance study, patients with any type of cancer receiving chemotherapy regimens with a high risk of febrile neutropenia (FN) were included if they were prescribed pegfilgrastim for FN prophylaxis. The primary objective of this study was to assess the safety and the secondary objective was to assess the effectiveness of pegfilgrastim in the prevention of FN in cancer patients. RESULTS: A total of 654 patients (51.73 ± 15.12 years of age) were enrolled and 3615 cycles of pegfilgrastim injections were recorded. The most common malignancies among the study patients were breast cancer (n = 192, 29.36%), lymphoma (n = 131, 20.03%), and gastric cancer (n = 65, 9.94%). The median (Q1, Q3) number of pegfilgrastim cycles per patient was 6 (4, 7). A single 6 mg dose was injected in 99.17% of the cycles. A total number of 816 adverse events (AEs) were reported in 246 patients (37.62%). Bone pain was recorded in 141 patients (21.56%) and in 440 cycles (12.17%). Among all patients, 45 patients (6.88%) experienced FN 51 times, and FN frequency was 1.4% among cycles. Moreover, 14 (2.14%) patients were hospitalized following FN. Antibiotics were administered to 24 patients (3.67%) for FN treatment. CONCLUSION: The results from this post-marketing surveillance study support the safety and effectiveness of PegaGen® used for the prevention of chemotherapy-induced FN in patients with various types of cancer and treatment regimens. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT04460079.
