Brief Summary:
The objective of this clinical trial was to evaluate whether DF2156A has a potential in improving the clinical outcome in patients with active blistering bullous pemphigoid (BP) to warrant its further development. The safety of DF2156A in the specific clinical setting was also evaluated.
Detailed Description:
The study was a phase 2, multicentre, single arm, pilot study. It has been designed to determine if DF2156A has sufficient activity to warrant its further development.
A total of twelve (12) BP patients were planned to be involved. They were planned to receive DF2156A orally at the dose of 150 mg twice a day for a maximum of 14 days.
Recruitment was intended to be competitive among the study sites, until the planned number of patients is enrolled. Competitive recruitment has been chosen to increase the speed of recruitment and to account for any unexpected occurrence at a site that negatively impact enrolment rate.
The single arm design has been chosen as an appropriate tool for this pilot phase 2 study, considering that BP is a rare disease where a placebo control is not acceptable. Moreover, as there is no spontaneous acute recovery from the active blistering condition, any improvement in patient outcome can be attributed to a positive effect of the Investigational Product.
Each patient was intended to be involved in the study for a screening period, for 14 days of treatment, for all required measurements up to hospital discharge (planned on day 8+1 of treatment) and for one assessment occasion on day 15+1, either during hospital stay or after hospital discharge (out-patient visit). An optional post-treatment visit might be scheduled at day 30+3.
Due to the lack of efficacy observed at 1/3 of the enrollment at the investigated dosage, the patients' enrollment was interrupted and trial, hence, was early terminated. More precisely, only 1 of the 4 enrolled patients completed the study's 14-day treatment period. The remaining 3 patients were discontinued from the study early (1 patient due to treatment failure and 2 patients who were discontinued and admitted to rescue therapy).
While DF2156A appeared to be safe and was generally well-tolerated with only mild AEs reported in 3 patients (and no deaths, SAEs, or discontinuations from the study due to AEs), the limited sample size of the safety population prevents any overall conclusions of safety regarding the investigational product. For this reason no results other than listings are available.
