Allergic asthma has a considerable burden on the quality of life. A significant portion of moderate-to-severe allergic asthma patients need omalizumab, an anti-immunoglobulin-E monoclonal antibody, as an add-on therapy. In this phase III clinical trial P043 (Zerafil
Multiple sclerosis is an inflammatory demyelinating disease and represents a global health concern. Ocrelizumab, a humanized IgG monoclonal antibody, selectively targets CD20 on B cells and CD20-expressing T cells. This study aimed to compare the efficacy and safety of the biosimilar ocrelizumab candidate (Xacrel) to the originator product (Ocrevus) in Relapsing Multiple Sclerosis (RMS) patients. In this randomized trial, patients received either Xacrel or Ocrevus for 96 weeks. The primary endpoint was the equivalency of the medications in reducing the annualized relapse rate (ARR) at week 48. The secondary endpoints included time to the onset of disability progression confirmed at 12 and 24 weeks, the proportion of relapse-free patients, magnetic resonance imaging (MRI) evaluations, safety assessments, and immunogenicity over 96 weeks. A total of 170 patients were randomized (1:1 ratio). In the per protocol analysis, the upper and lower limits of 95% two-sided confidence intervals of difference between treatments in the 48-week ARR rate were in the predefined margin of − 0.2 to 0.2 (− 0.002; 95% CI − 0.080 to 0.075). The two products were also comparable in terms of other efficacy parameters, safety, and immunogenicity. The results confirmed that Xacrel is equivalent to Ocrevus in terms of 48-week ARR in RMS patients, with no considerable difference in other efficacy parameters and the safety profile during the 96 weeks. The trial was registered in Iranian registry of clinical trials (IRCT) on 10/06/2019 with the registration number of IRCT20150303021315N13 and in Clinicaltrials.gov on 19/07/2021 with the registration code of NCT04966338.
The safety of teriparatide has been studied in various phase III and phase IV trials. However, a postmarketing study of the biosimilar of teriparatide, CinnoPar
Background Trastuzumab is a humanized monoclonal antibody against the human epidermal growth factor receptor 2 (HER2). This post-marketing surveillance evaluates the safety of a trastuzumab biosimilar (AryoTrust), produced by AryoGen Co. Iran in Iranian women with HER2-positive non-metastatic breast cancer (BC).
Background: CinnoRA® (CinnaGen, Iran) is a biosimilar candidate for the reference adalimumab, Humira® (AbbVie, USA). This study aimed to compare the pharmacokinetics, safety, and tolerability of these products in healthy participants.Research design and methods: In this phase-I, randomized, double-blind trial, 74 healthy adult volunteers were randomized in a 1:1 ratio to receive a single 40 mg subcutaneous injection of CinnoRA® or Humira®. Serum concentrations of adalimumab were analyzed using a validated enzyme-linked immunosorbent assay and were evaluated by non-compartmental methods. Pharmacokinetic equivalence between groups was determined using the standard equivalence margins of 0.80 to 1.25.Results: The baseline characteristics were similar between study groups. Mean values of area under the serum concentration-time curve from time zero to infinity (AUCinf) and maximum serum concentration (Cmax) were similar in study groups and the 90% confidence intervals for the geometric mean ratios of AUCinf and Cmax were within the prespecified equivalence margins. There were no deaths and the total number of treatment-related adverse events was not statistically different between groups (p-value = 0.19).Conclusions: The results clearly showed the pharmacokinetic similarity of the biosimilar adalimumab to the originator. CinnoRA® was safe and well-tolerated in healthy volunteers, with no significant differences in safety from the reference product.Trial Registration: The trial is registered at ClinicalTrials.gov (# NCT03273192).
