Long-term, Safety, Tolerability and Efficacy Study of AFQ056 in Adult Patients With Fragile X Syndrome

This study has been terminated.
(Study treatment AFQ056 failed to demonstrate efficacy in the adult patient with Fragile X Syndrome in 2 other clinical studies (CAFQ056B2214 and CAFQ056A2212))

The purpose of this study is to generate long-term safety, tolerability and efficacy data for AFQ056 in eligible adult patients with FXS who have participated in the CAFQ056A2212 (NCT01253629).study and patients who have participated in the previous proof-of-concept study CAFQ056A2204 (NCT00718341).

Primary Outcome Measures:
  • Incidence and Severity of Adverse Events (AEs) and Serious Adverse Events (SAEs). [ Time Frame: Prior to first dose in extension study, Baseline (start of study treatment in extension study) to End of trial ]
    Adverse events were summarized for the open-label treatment period, where the open-label treatment period is defined based on how AEs were collected and reported according to the manner in which patients entered the current study and which treatment (AFQ056 or placebo) they were receiving in the previous study. AEs which were continuing from the core study or that started after the end of core study but prior to first dose of open-label study medication in the extension study for Category 1 patients are shown under ('Prior to Ext. first dose'). AEs which started during the open-label treatment period are presented based on the last AFQ056 dose taken on or before the onset date of the AE (25 mg bid; 50 mg bid; 75 mg bid; or 100 mg bid). No efficacy data presented as study was terminated

Enrollment: 148
Study Start Date: August 2011
Study Completion Date: September 2014
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: AFQ056 100 mg (Bid)
All patients initiated treatment with AFQ056 at a starting dose of 25 milligram (mg) twice daily. The dose was titrated from 25mg bid to 50mg bid, 75mg bid and 100mg bid at weekly intervals. Dose adjustments (up- and down titrations) were permitted as needed to manage any tolerability issues and to ensure that patients reach their highest tolerated dose not to exceed 100mg bid.
Drug: AFQ056
The investigational drug, AFQ056, will be provided as hard gelatin capsules. Two different oral dosage strengths, identical in appearance, will be used.

Detailed Description:
A 148 patients were enrolled into this treatment extension trial conducted for at least 3 years. This extension trial was terminated after the decision to terminate the AFQ056 development program. The decision was based on the results of two randomized, double blind, placebo controlled phase IIb trials in adult and adolescent FXS patients (CAFQ056A2212 and CAFQ056B2214respectivly), both of which failed to demonstrate efficacy in the FXS population. As this extension trial was terminated, only the primary objective and safety are represented.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion criteria Group 1 patients

  • Had to have completed the CAFQ056A2212 study or another study of AFQ056 which included adult FXS patients within one week of enrollment into the open-label study.
  • Females of child-bearing potential had to follow protocol requirements with respect to contraception.
  • Have a caregiver or caregivers who spent, on average, at least six hours per day with the patient, who were willing and capable of supervising treatment, providing input into efficacy and safety assessments, and accompanying the patient to study visits.

Group 2:

  • Had to have:
  • Completed Study CAFQ056A2204.
  • Completed Study CAFQ056A2212 or another study of AFQ056 which included adult patients with FXS but enrollment into the current study was delayed for more than a week.
  • Discontinued prematurely from Study CAFQ056A2212 or another study of AFQ056 which included adult patients with FXS due to intolerability of the dosage in the patient's assigned treatment group.
  • Females of child-bearing potential had to follow protocol requirements with respect to contraception.
  • Have a caregiver or caregivers who spent, on average, at least six hours per day with the patient, who were willing and capable of supervising treatment, providing input into efficacy and safety assessments, and accompanying the patient to study visits

Exclusion criteria
