원발성 면역 혈소판 감소증이 있는 성인 환자에서 Efgartigimod PH20 피하주사제의 안전성 및 효능을 평가하기 위한 3상 연구 (ADVANCE SC+)
원발성 면역 혈소판 감소증이 있는 성인 환자에서 Efgartigimod(ARGX-113) PH20 피하 피하의 안전성 및 효능을 평가하기 위한 3상, 다기관, 공개, 장기 시험
The main aim of the study is to evaluate the safety and efficacy of efgartigimod PH20 SC (subcutaneous) in adult patients with primary immune thrombocytopenia (ITP). Participants who completed the 24-week trial period of the ARGX- 113-2004 trial are given the opportunity to enter into this open-label extension trial and receive efgartigimod PH20 SC.
Participants will be offered the opportunity to continue in this trial if they have completed the first 52-week treatment period unless efgartigimod becomes commercially available for patients with primary ITP or becomes available through another program for patients with primary ITP, whichever comes first. A maximum of three additional 52-week treatment periods will be offered to the participant to continue this trial.
The total trial duration per participant is up to 4 years (52-week treatment period, extendable with three additional 52-week treatment periods) + 8 weeks follow-up period.
