Brief Summary:

The development of Auto Immune bullous Diseases (AIBD) results from a complex interaction between innate and adaptive immune systems. Bullous pemphigoid (BP), the most frequently encountered AIBD, predominantly affects elderly patients above 70 with an estimated incidence of 21.7 new cases/million/year in France.Interestingly, coversin, an anti-C5a and -leukotriene B4 small molecule, is currently used in a phase IIA clinical trial in BP patients (NCT04035733). However, although overall C5-blocking drugs are potentially interesting, they are likely to interfere with C5a-C5aR2-axis activation as well, a pathway that has recently proved protective in BP 12. The main objective is to investigate the clinical efficacy of an anti-C5aR1 antibody in addition to superpotent topical steroids compared to superpotent topical steroids alone in BP patients at 3 months.It is a case-controlled, randomized, open-labelled, and multicenter phase II clinical trial. Four Dermatologic French centers (Nice, Marseille Nord, Marseille Timone and Montpellier university hospitals) specialized in the in the care of BP patients will be participating in the study. It is expected that forty subjects will be included in this trial.

Conversely, a more targeted inhibition of C5a-C5aR1 axis might be more effective in BP, sparing the potentially protective effect of C5a-C5aR2 interaction.

Avdoralimab (IPH5401), a specific anti-C5aR1 monoclonal antibody, has already been credited of a good safety profile in the treatment of solid tumors and rheumatoid arthritis. The investigators hypothesize that avdoralimab might be a safe and effective treatment in BP patients

Arms and Interventions

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Drug

Patients in this group will additionally receive 3 s.c. injections of avdoralimab every week during 12 weeks

They receive 0.05% Clobetasol propionate cream as follows:

  • Patients of less than 45kg of body weight: 2 tubes of 10g/d
  • Patients of 45kg and above of body weight: 3 tubes of 10g/d Topical steroids will be applied every day until 15 days after the healing of the last bullous lesions
 Drug: Avdoralimab (IPH5401)
Preparation of avdoralimab and preparation of the syringes are to be performed aseptically by site pharmacy qualified personnel.
Conventional therapy

Superpotent topical steroids are the gold standard treatment for BP. All patients will receive 0.05% Clobetasol propionate cream as follows:

  • Patients of less than 45kg of body weight: 2 tubes of 10g/d
  • Patients of 45kg and above of body weight: 3 tubes of 10g/d Topical steroids will be applied every day until 15 days after the healing of the last bullous lesions
 Other: Control

Superpotent topical steroids are the gold standard treatment for BP. All patients will receive 0.05% Clobetasol propionate cream as follows:

  • Patients of less than 45kg of body weight: 2 tubes of 10g/d
  • Patients of 45kg and above of body weight: 3 tubes of 10g/d Topical steroids will be applied every day until 15 days after the healing of the last bullous lesion


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Complete Clinical Remission [ Time Frame: At 3 Months ]
    To investigate the clinical efficacy of an anti-C5aR1 antibody in addition to superpotent topical steroids compared to superpotent topical steroids alone in BP patients.The efficacy will be evaluated through the proportion of patients in complete clinical remission (CCR) at 3 months without any relapse during the study period. The CCR will be defined as the absence of new bullous and skin inflammatory lesions and absence of pruritus for at least 2 weeks.


Secondary Outcome Measures :
  1. The delay [ Time Frame: At 3 months ]
    To compare between the treatment groups the delay to complete clinical remission (CCR)

  2. Initial Clinical Remission [ Time Frame: At 3 months ]
    To compare between the treatment groups the delay to initial clinical remission (ICR)
