Официальное название

TPO-RA Plus Baricitinib vs. TPO-RA in Patients With ITP : A Randomized, Open-label Trial

Обзор

This is a prospective, randomized, controlled trial. ITP patients who failed prior full-does TPO-RA monotheray for 14 days. Patients are randomly assigned at a 1:1 ratio to receive baricitinib plus TPO-RA or TPO-RA alone. Patients are randomly assigned at a 1:1 ratio to receive baricitinib plus TPO-RA or TPO-RA alone. The primary endpoint was the 14-day overall response rate without any rescue therapy.

Подробное описание

This is a prospective, randomized, controlled trial.Eligible patients were at least 18 years old, had a diagnosis of primary ITP and did not respond after receiving TPO-RA (hetrombopag or eltrombopag) at the full dose (hetrombopag 7.5mg per day or eltrombopag 75 mg per day) for 14 days (platelet count below 30×10\^9/L or a value less than a 2-fold increase from their baseline platelet count). Patients are randomly assigned at a 1:1 ratio to receive baricitinib plus TPO-RA or TPO-RA alone. Both groups will continue their prior full-dose TPO-RA therapy for 14 days (day 1-14), while baricitinib was given orally at a dose of 2 mg twice daily concomitantly in the combination group for 14 days (day 1-14). The primary endpoint was the 14-day overall response rate without bleeding and any rescue therapy. The secondary endpoints included the 28-day overall response rate, 14-day complete response rate, the 28-day complete response rate, time to response, WHO bleeding scores, health-related quality of life, and adverse events.
