Naše práce se věnuje porovnání klinické účinnosti a bezpečnosti biosimilárního adalimumabu FKB327 (Hulio®) s originálním adalimumabem (Humira®). Celkem 62 nemocných (35 léčených FKB327 a 27 léčených originálním adalimumabem) bylo sledováno po dobu 14 týdnů. U nemocných v obou skupinách došlo k poklesu zánětlivých parametrů (C-reaktivní protein, fekální kalprotektin) a klinické aktivity nemoci (Harveyův-Bradshawův index) bez statisticky významného rozdílu mezi biosimilárním a originálním adalimumabem. Počet významných infekcí, které vedly k předčasnému ukončení léčby, byl nízký a srovnatelný v obou skupinách pacientů (kohorta FKB327 - 5,7 %, kontrolní skupina - 3,7 %).

Aim of our study was to compare clinical efficacy and safety of biosimilar adalimumab FKB327 (Hulio®) with the original (Humira®). In total, 62 patients (35 treated with FKB327 and 27 treated with originál adalimumab) were followed for the period of 14 weeks. In both groups, we observed decrease of inflammatory parameters (C-reactive protein, fecal calprotectin) and clinical activity (Harvey-Bradshaw index) without a statistically significant difference between biosimilar and original adalimumab. The proportion of patients in which clinically significant infections led to an early treatment withdrawal was low and similar in both groups (FKB327 - 5.7%, original adalimumab - 3.7%).

OBJECTIVE: To compare the efficacy, serum drug concentrations, immunogenicity, and safety of FKB327 with the adalimumab reference product (RP) in combination with methotrexate in patients with moderate-to-severe, active rheumatoid arthritis (RA). METHODS: Patients were randomized 1:1 in a double-blind study (NCT02260791), received 40 mg of FKB327 or RP by subcutaneous injection every other week for 24 weeks (Period I), then re-randomized 2:1, remaining on the same study drug or switching to the other up to week 54 in an open-label extension (Period II, NCT02405780). Efficacy was evaluated using American College of Rheumatology (ACR20) response rate difference at week 24 with equivalence margins of ± 13% and - 12% to + 15% using 95% and 90% confidence intervals (CIs), respectively. Efficacy, serum drug concentrations, immunogenicity, and safety were compared at week 54. RESULTS: A total of 730 patients were randomized in Period I (n = 367 FKB327, n = 363 RP), and 645 transitioned to Period II (n = 216 FKB327-FKB327, n = 108 FKB327-RP, n = 108 RP-FKB327, n = 213 RP-RP). At week 24, ACR20 response rates were 74.1% with FKB327 versus 75.7% with RP. 95% and 90% CI of the response rate difference were - 7.9 to 4.7% and - 7.3 to 3.6%, respectively, meeting predefined equivalence margins. The ACR20 response rate remained over 70% of patients to week 54 with all treatment sequences. In Period I, mean trough serum drug concentrations were slightly higher for patients receiving FKB327 than those receiving RP. Mean concentrations were stable over time and reflected steady state in Period II. The proportions of patients with samples positive for neutralizing antidrug antibodies (ADAs) were comparable (57.7% with FKB327 vs. 55.5% with RP) at week 24, and no consistent difference in ADA were seen between continuous and switched treatments in Period II. Efficacy was slightly reduced in the small proportion of patients with high ADA titers in all treatment groups. No clinically significant differences were observed in the incidence of commonly reported treatment-emergent adverse events between the treatments across Periods I and II. CONCLUSION: FKB327 was equivalent to RP in clinical efficacy and demonstrated comparable safety and immunogenicity in patients with moderate-to-severe RA. No effect of switching between FKB327 and RP was observed. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02260791, Registered 29 July 2014. ClinicalTrials.gov, NCT02405780, Registered 17 July 2015.

OBJECTIVE: The adalimumab biosimilars FKB327 and GP2017 were approved for the therapy of patients with inflammatory bowel disease (IBD). Relatively few prospective studies with biosimilar adalimumab in patients with IBD have been published. The aim of this prospective observational study was to evaluate the effectiveness and safety of the biosimilar adalimumab. MATERIAL AND METHODS: Adalimumab biosimilars FKB327 (Hulio®) and GP2017 (Hyrimoz®) were indicated to 50 naive patients in terms of biological therapy with Crohn's disease (CD) or ulcerative colitis (UC). Effectiveness of therapy was evaluated via the Crohn's Disease Activity Index [CDAI] or the Mayo Scoring System [MSS] in patients with CD or UC, respectively, before and after 12 weeks. Additional goals were to evaluate weight changes, laboratory tests and complications or adverse events of this therapy. RESULTS: In CD patients, remission (CDAI <150) was achieved in 73.5% of cases, partial response (≥70-point decrease in CDAI score from baseline) in 11.8%, no response in 11.8% and 2.9% patients discontinued therapy. In UC patients, remission (total score on partial Mayo index ≤2 points) was achieved only in 18.8% of cases, partial response (≥2-point decrease in partial Mayo score from baseline) in 43.8%, no response in 25.0% and 12.5% patients discontinued therapy. There were statistically significant improvements in CDAI, MSS, haemoglobin, fecal calprotectin, albumin and CRP serum levels after 12 weeks of therapy. Seven adverse events were identified, three of which resulted in therapy being discontinued. CONCLUSIONS: This prospective observational study proved the effectiveness of the adalimumab biosimilars FKB327 and GP2017 in IBD.
