简要总结
Patients diagnosed with bullous pemphigoid were confirmed based on the investigators national diagnostic criteria. Patients who meet all inclusion criteria and conflict the exclusion criteria will receive NPB-01(intravenous immunoglobulin) 400mg/kg/day for five consecutive days or Placebo(physiological saline). Subsequently, efficacy of NPB-01 for therapy of bullous pemphigoid will evaluate using pemphigoid activity score involving skin lesion area and Number of new blisters.
As a safety endpoint, the safety of NPB-01 will be investigated the occurrence of adverse events by 57 days after the start of the study treatment.
