Summary
Brief summary
ARGX-113-2010 is an open-label extension study with the aim to provide supporting evidence
that efgartigimod PH20 SC is a safe and effective long-term treatment for bullous pemphigoid
(BP), providing symptom control and eventually remission, while also reducing the cumulative
exposure to oral corticosteroids (OCS).

All participants who complete the end-of-treatment period (EoTP) visit at week 36 in
ARGX-113-2009 will be invited to enroll.

In ARGX-113-2009, participants received efgartigimod PH20 SC or placebo with concurrent OCS,
or rescue therapy (without efgartigimod PH20 SC or placebo). Depending on their clinical
status at the time of rollover into ARGX-113-2010, participants may stop, continue or
initiate efgartigimod PH20 SC treatment. In ARGX-113-2010, participants will stop
efgartigimod PH20 SC treatment when they achieve complete remission (CR) or partial remission
(PR) while being off other concurrent BP therapy for at least 8 weeks. Participants not in CR
or PR while off OCS for =8 weeks and not on rescue therapy will either start or continue
efgartigimod PH20 SC treatment, while maintaining the treatment allocation of ARGX-113-2009
blinded. Participants may also be retreated with efgartigimod PH20 SC after a relapse. In
this study, loading doses of 2000 mg (on day 1 and day 8 of a treatment course) and weekly
maintenance doses of 1000 mg will be used.
