Brief Summary:
A drug repositioning effort provided evidence supporting the possible use of Etravirine, a drug approved for the treatment of HIV infections in patients starting from 2 years of age, as a treatment for FA. We found that Etravirine is able to increase Frataxin protein both in vitro - in cells derived from FA patients - and in vivo - in the heart and skeletal muscle of Frataxin-deficient YG8 mice. Because of these findings, and since Etravirine displays a generally favorable safety profile, we plan to launch an open-label, phase 2 clinical trial aimed at assessing the safety and efficacy of Etravirine in FA patients. We aim at recruiting 30 FA patients. 15 will be treated with Etravirine for 4 months at 200 mcg/day and 15 will be treated with Etravirine for 4 months at 400 mg/day. Efficacy primary endpoint will be represented changes in peak VO2 as measured by incremental cycle ergometer exercise test. Secondary endpoints will include maximal workload, SARA score, cardiac measures, Frataxin protein levels in peripheral blood mononuclear cells and molecular analysis of Frataxin mRNA translation efficiency. Complete sets of data will be collected 4 months before the start of the treatment (T -4), at the start (T0), after 2 months (T2), at the end of the treatment (T4) and 4 months after the termination of the treatment (T8).

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 30 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: dose comparison in open label pilot study
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 2 Clinical Trial to Test the Safety and Efficacy of Etravirine in Friedreich Ataxia Patients
Actual Study Start Date : September 17, 2020
Estimated Primary Completion Date : October 31, 2022
Estimated Study Completion Date : November 30, 2022

Arm Intervention/treatment
Active Comparator: Etravirine Dose 1
Etravirine dose 200 mg per diem(100+100)
Drug: Etravirine Tablets
Daily etravirine BID with 100 or 200 tablets for 4 months

Active Comparator: Etravirine Dose 2
Etravirine dose 400 mg per diem (200+200)
Drug: Etravirine Tablets
Daily etravirine BID with 100 or 200 tablets for 4 months

Primary Outcome Measures :
  1. Adverse event number and severity [ Time Frame: 4 months ]
    description and count of AE and SAE to document the safety of etravirine treatment at 200 mg/die and 400mg/die in FA patients

Secondary Outcome Measures :
  1. VO2 max increase [ Time Frame: 12 months ]
    efficacy of etravirine treatment in increasing aerobic capacity in FA patients comparing pre and post treatment periods

Other Outcome Measures:
  1. Scale for the Assessment and Rating of Ataxia [ Time Frame: 12 months ]
    Scale for the Assessment and Rating of Ataxia (SARA) score change comparing pre-, during- and post- treatment evaluations. SARA scores ataxia on a 0-40 points scale where 0 means no ataxia and 40 most severe ataxia

  2. Cardiac wall thickness (in mm) [ Time Frame: 12 months ]
    cardiac wall thickness (in mm) as measured by standard Echo cardiography

  3. Frataxin measurement [ Time Frame: 12 months ]
    Frataxin protein content in peripheral blood mononuclear cells

  4. short form 36 scale for quality of life [ Time Frame: 12 months ]
    changes in QoL as measured by the short form 36 (SF36) scale and disability as measured with the World Health Organization Disability Assessment schedule 2.0 (WHO-DAS 2.0) during the study period. Both tools are graded on a 0-100 scale where 100 is best and 0 is worst.
