| Summary: | ABSTRACT Background Imiglucerase (Cerezyme; Sanofi, Paris, France), an analogue of β‐glucocerebrosidase produced by recombinant DNA technology, has been a safe and effective treatment for Gaucher disease (GD) for over 25 years. A new imiglucerase, Abcertin (Seongnam‐si, Gyeonggi‐do, Republic of Korea) has shown a similar safety and efficacy profile in previous clinical studies. This study compared the pharmacokinetics, immunogenicity, safety, and tolerability to EU‐sourced Cerezyme following a single 60 IU/kg dose. Methods This phase 1, single‐center, randomized, double‐blind, two‐way crossover study enrolled 36 healthy volunteers aged 18–45 years. Participants were randomly assigned to receive either Abcertin or Cerezyme in a predetermined sequence. Results Abcertin reached peak plasma concentrations at a median tmax of 61 min (range: 40–121 min). The mean Cmax, AUC0–last, and AUC0–inf were 115.4 mU/mL, 12,190 min·mU/mL, and 12,210 min mU/mL, respectively, indicating bioequivalence to Cerezyme. The mean t½, CL, and Vz were 6.88 min, 376.7 mL/min, and 3.62 L, respectively, and were comparable between the two treatments. One participant in the Cerezyme group developed anti‐drug antibodies, which were non‐neutralizing A total of 24 subjects experienced treatment‐emergent adverse event (TEAE). The most common TEAE was headache (3 in the Abcertin group and 5 in the Cerezyme group), followed by general disorders and administration site condition (3 in Abcertin group and 5 in Cerezyme group). Two participants in the Cerezyme sequence experienced severe TEAEs: one had a urinary tract infection, and the other developed urticaria, which leading to study withdrawal. Conclusion Abcertin demonstrated pharmacokinetic equivalence to Cerezyme, with a comparable safety, immunogenicity, and tolerability profile. These findings support its potential as an affordable biosimilar for GD treatment. |
