Summary

The goal of this clinical trial is to demonstrate equivalent efficacy and comparable safety of the drug GP40141 (GEROPHARM, Russia) in comparison with the drug Nplate® (Amgen, the Netherlands). the main questions are 1. Assess the effectiveness of GP40141 in comparison with Nplate®. 2. Assess the immunogenicity of GP40141 in comparison with the drug Nplate®. 3. Assess the safety of GP40141 in comparison with the drug Nplate®. 4. Assess the safety of changing romiplostim and eltrombopag to GP40141. 5. Assess the pharmacokinetic parameters of the study drugs in patients with primary immune thrombocytopenia. Participants divided into 2 cohorts (naïve or treated with a thrombopoietin receptor agonist) will receive romiplostim and platelet response, immune response and adverse reactions will be assessed.

Detailed description

The study will be conducted in adult patients with persistent or chronic primary immune thrombocytopenia. Patients both naïve to treatment with a thrombopoietin receptor agonist (cohort 1) and those who have previously received therapy (cohort 2) will be included. Cohort 1: Adult steroid-dependent or steroid-refractory patients with persistent or chronic primary immune thrombocytopenia (PIT) with or without a history of splenectomy who have not previously received thrombopoietin receptor agonist (TPO-RA) therapy. Cohort 2: Adult patients with persistent or chronic primary immune thrombocytopenia receiving TPO-RA (romiplostim or eltrombopag) for ≥12 weeks and with sustained response status at screening.
