ABSORICA in Patients With Severe Recalcitrant Nodular Acne
- Registration Number
- NCT02457520
- Lead Sponsor
- Sun Pharmaceutical Industries Limited
- Brief Summary
This is an uncontrolled, open-label study being conducted in approximately 200 healthy males, non-pregnant, non-nursing females, age 12 to 45 years, with severe recalcitrant nodular acne.
ABSORICA® (isotretinoin) capsules 0.5 mg/kg/day will be administered for 4 weeks followed by 1.0 mg/kg/day for 16 weeks. Female subjects consenting to use two forms of birth control or abstinence are included.
- Detailed Description
This study is designed to collect efficacy, safety, and quality of life (QOL) data from subjects who receive Absorica® without food. The study will investigate the treatment efficacy, frequency of relapse once the treatment has been discontinued, quality of life during the active treatment and during a 2-year post treatment period and the overall safety of treatment with Absorica®.
This is a single-arm, open-label study consisting of 2 phases: a 20-week (5-month) open-label Active Treatment Period (ATP) and a 104-week (2-year) post treatment period (PTP). The total study duration is to be 124 weeks, excluding a screening period. During the ATP, after week 2 visit, visits will be scheduled at 4-week intervals for a total of 8 visits (1 screening visit, 1 baseline visit, and 6 on-study visits). During the PTP, the first visit will be 4 weeks after End of Treatment (EOT), the second visit will be 12 weeks after EOT, and subsequent visits will be scheduled at 26-week (± 2 weeks) intervals for a total of 6 visits.

- Primary Outcome Measures
Name Time Method Active Treatment Period: Total Acne-Specific Quality of Life Score at Week 20 Week 20 There are 4 domains: self-perception (22 questions), role-social (50 questions), role-emotional (33 questions), and acne symptoms (85 questions) in the acne-QOL questionnaires.
Calculation of the domain scores was accomplished by summing all item responses within each domain.
Self-perception: The range of possible scores is 0 to 30 points. Role-social: The range of possible scores is 0 to 24 points. Role emotional: The domain scores range from 0 to 30 points. Acne symptoms: The domain scores range from 0 to 30 points.Primary Efficacy Endpoint, Post-treatment Period: Subjects Requiring Retreatment During the Post-treatment Period and Time to Retreatment 20 weeks subjects who were at least 75% compliant with their assigned treatment, had no major protocol violations, had a Week 20 count of total nodular lesions, and did not use any disallowed medications during the 20 weeks of treatment. (Retreated with Oral Isotretinoin Per Protocol Population).
- Secondary Outcome Measures
