|Condition or disease||Intervention/treatment||Phase|
|Epidermolysis Bullosa Epidermolysis Bullosa Simplex||Drug: diacerein 1% ointment||Phase 2|
This is an international, multicenter, open-label, long term extension study evaluating the safety of topical Diacerein 1% Ointment for the treatment of subjects with EBS. At Visit 1, EBS subjects who completed the CCP-020-301 double-blind safety and efficacy study or participated in the CCP-020-101 PK study (feeder studies) who meet all the inclusion/exclusion criteria will be eligible to complete 2 treatment cycles of CCP-020.
Each treatment cycle will consist of 8 weeks on treatment (once-daily, at home study medication applications) followed by 8 weeks off treatment (only Investigator approved bland, non-medicated emollient/moisturizer, routine cleansing products and sunscreens) with a maximum of 2 treatment cycles allowed for up to 52 weeks.
At Baseline Visit (corresponding to the final study visit of the feeder study), the investigator will perform a clinical assessment and determine if any of the subject's lesions require treatment (up to 30% BSA). If the subject has active lesions as determined by the Investigator's clinical assessment, the subject will initiate a cycle of once-daily, at home study medication application to their EBS lesions for 8 weeks (treatment period) followed by an 8-week period where no treatment will be administered. Subjects presenting with no active lesions (as determined by the Investigator's clinical assessment) will not begin treatment and instead, will be instructed to return to the clinic for re-evaluation in 8 weeks or upon worsening of EBS lesions, whichever happens first.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||80 participants|
|Intervention Model:||Single Group Assignment|
|Intervention Model Description:||This is an international, multicenter, open-label, long term extension study evaluating the safety of topical Diacerein 1% Ointment for the treatment of subjects with EBS. At Baseline Visit, EBS subjects who participated the CCP-020-301 double-blind safety and efficacy study or participated in the CCP-020-101 PK study (feeder studies) and who meet all the inclusion/exclusion criteria will be eligible to enroll in this study.|
|Masking:||None (Open Label)|
|Masking Description:||Each treatment cycle will consist of 8 weeks on treatment, followed by 8 weeks off treatment with a maximum of 2 treatment cycles allowed for up to 1 year. Subjects should be assessed at minimum every 8 weeks for disease activity. Once a subject completes two cycles of treatment or reaches Week 52, the subject will be discharged from the study. Subjects may not start a new treatment cycle past Week 36 from Baseline Visit without prior sponsor approval. The duration of a subject's participation in the extension study may be as short as 32 weeks or as long as 52 weeks depending on the cycle initiation schedule for each individual subject.|

Experimental: Treatment period
Subjects with active lesions as determined Investigator's clinical assessment, will initiate a cycle of applying diacerein 1% ointment once-daily, study medication, at home to their EBS lesions for 8 weeks.
Following the Treatment Period, subjects will go Off Treatment for 8 weeks using only investigator approved bland, non-medicated emollient/moisturizer, routine cleansing products and sunscreens. As determined Investigator's clinical assessment, subjects may enter into another Treatment Period of 8 weeks.
The duration of a subject's participation in the extension study may be as short as 32 weeks or as long as 52 weeks depending on the cycle initiation schedule for each individual subject.
Drug: diacerein 1% ointment
Topically apply study medication to lesions identified by the Investigator that require.
Other Name: CCP-020
- Evaluate Safety and Tolerability of Diacerein 1% Ointment [ Time Frame: From Baseline Visit to 16 weeks, not to exceed 52 weeks cyling between treatment and off treatment periods ]The primary objective of this study is to evaluate the long term safety and tolerability of diacerein 1% ointment in subjects with EBS that previously participated in studies CCP-020-301 or CCP-020-101. Safety will be evaluated in terms of the occurrence of Adverse Events. All adverse events, including observed or volunteered problems, complaints, or symptoms, are to be recorded.
