About this study
Official title: NPB-01(Intravenous Immunoglobulin) Therapy for Patients With Bullous Pemphigoid Unresponsive to Corticosteroids: Randomized, Double-Blind, Placebo Control,Parallel Assignment Study(PhaseⅡ).
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.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing NPB-01 in people with Bullous Pemphigoid, run by Nihon Pharmaceutical Co., Ltd at 1 site in Japan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Oct 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Skin lesion area (%), Number of new blisters/day, Pemphigoid Activity Score, Pemphigus Disease Area Index(PDAI), anti-BP180 and -BP230 antibody titers, Steroid dose, Time to escape from the protocol and its ratio (time frame: 57 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Oct 2010.
