Evaluation of (R)-Roscovitine Safety and Effects in Subjects With Cystic Fibrosis, Homozygous for the F508del-CFTR Mutation
- Registration Number
- NCT02649751
- Lead Sponsor
- University Hospital, Brest
- Brief Summary
This is a phase II, dose ranging, multicenter, randomized, double-blind, placebo-controlled study.
The aim of this study is to assess the safety of increasing doses of roscovitine administered orally for 4 cycles of 4 consecutive days (treatment "on") separated by a 3 days treatment free period (treatment "off") in adult CF subjects with Cystic Fibrosis carrying 2 Cystic Fibrosis causing mutations with at least one F508del-CFTR mutation and chronically infected with Pseudomonas aeruginosa.
This study involved 36 Cystic Fibrosis patients: 24 treated and 12 controls.
- Detailed Description
ROSCO-CF is a phase II, dose ranging, multicenter, double-blind, placebo controlled study to evaluate safety and effects of (R)-roscovitine in subjects with Cystic Fibrosis carrying 2 Cystic Fibrosis causing mutations with at least one F508del-CFTR mutation and chronically infected with Pseudomonas aeruginosa.
The aim of this study is to assess the safety of increasing doses of roscovitine administered orally for 4 cycles of 4 consecutive days (treatment "on") separated by a 3 days treatment free period (treatment "off") in 36 adult cystic fibrosis subjects.
These 36 patients will be allocated to 3 groups of 12 subjects who will be randomized in a 2:1 ratio (active drug to matching placebo). In each group, 8 patients will receive roscovitine (200 mg, 400 mg, 2 X 400 mg in group 1, 2 and 3, respectively) and 4 will receive a matching placebo. Treatment will be provided by oral administration of capsules. Each patient will receive the same treatment throughout the 28 day study.
This phase II trial will give some preliminary information about safety and hints of effects of a new experimental treatment. If the data suggest that a short term treatment with roscovitine provides a safe, effective and convenient approach for CF patients chronically infected with Pseudomonas aeruginosa, patients participating in this proof of concept trial will be offered to participate in further longer term studies.
