What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Creatine Rephosphorylation Rate Post Exercise

    Creatine Rephosphorylation Rate post exercise measured using Phosphorus 31 Nuclear Magnetic Resonance (P-31 NMR)spectroscopy and calculated with correction according to muscular pH.

    Measured: Baseline (Week 0) to Week 12

Secondary outcomes (21)
  1. Peak Post Exercise Perfusion

    Peak post exercise perfusion (mL/mn/100 g of tissue) was assessed using Arterial spin labelling combined with Nuclear Magnetic Resonance imaging.

    Measured: Baseline (Week 0) to Week 12

  2. Time to Peak Perfusion

    Measured: Baseline (Week 0) to Week 12

  3. Perfusion-time Integral During the First 9 Minutes Post Exercise.

    The integral of 'peak perfusion' over a period of 9 minutes post exercise.

    Measured: Baseline (Week 0) to Week 12

  4. Muscle Reoxygenation Rate Post Exercise.

    Muscle reoxygenation rate post exercise was assessed using Myoglobin Hydrogen-1 Nuclear Magnetic Resonance spectroscopy.

    Measured: Baseline (Week 0) to Week 12

  5. Muscle Trophicity: Maximum Cross Section of Muscle

    Muscle trophicity measured using Phosphorus 31 Nuclear Magnetic Resonance (P-31 NMR)spectroscopy and calculated based on maximum cross section of muscle (cm^2)

    Measured: Baseline (Week 0) to Week 12

  6. Developed Force During the Exercise Bout

    Developed force during the exercise bout measured using Phosphorus 31 Nuclear Magnetic Resonance (P-31 NMR)spectroscopy

    Measured: Baseline (Week 0) to Week 12

  7. Normalised Work Developed During the Exercise

    Normalised work developed during the exercise was derived as Work developed during the exercise/([60 X Maximum cross section of muscle]-1100).

    Normalised work measured using Phosphorus 31 Nuclear Magnetic Resonance (P-31 NMR)spectroscopy.

    Measured: Baseline (Week 0) to Week 12

  8. Metabolism Efficacy Index

    The metabolism efficacy index was derived as Normalised work x creatine phosphorylation rate (sec-1). [Normalised work was derived as Work developed during the exercise/(60 X Maximum cross section of muscle-1100)]. Greater values of Metabolism Efficacy index indicate improvement in skeletal muscle energetics while lower values indicate the reverse. Negative values obtained using the formula indicated severe levels of muscle weakness.

    Measured: Baseline (Week 0) to Week 12

  9. International Cooperative Ataxia Rating Scale [ICARS] (Total Score)

    The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales (i.e. Posture and gait disturbances, Kinetic functions, Speech disorders, \& Oculomotor disorders). Scores for each subscale quantify the extent of ataxia in each clinically important area and subscale scores are also summed to give a total score ranging from 0 to 100, with 100 indicative of the most severely affected outcome.

    Measured: Baseline (Week 0) to Week 12

  10. ICARS (Posture and Gait Disturbance Score)

    The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Posture and gait disturbances. Posture and gait disturbances score range from 0 to 34 (Higher scores indicate higher levels of impairment).

    Measured: Baseline (Week 0) to Week 12

  11. ICARS (Kinetic Function Score)

    The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Kinetic Function. Kinetic Function score range from 0 to 52 (Higher scores indicate higher levels of impairment).

    Measured: Baseline (Week 0) to Week 12

  12. ICARS (Speech Disorders Score)

    The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Speech Disorders. Speech Disorders Score range from 0 to 8 (Higher scores indicate higher levels of impairment).

    Measured: Baseline (Week 0) to Week 12

  13. ICARS (Oculomotor Disorders Score)

    The ICARS was used to measure the general clinical symptoms of Friedreich ataxia using four subscales including Oculomotor Disorders. Oculomotor Disorders score range from 0 to 6 (Higher scores indicate higher levels of impairment).

    Measured: Baseline (Week 0) to Week 12

  14. Timed 25-foot Walk Test

    Measured: Baseline (Week 0) to Week 12

  15. Nine Hole Peg Test (Dominant Hand)

    The nine hole peg test was used to assess cognitive function and in particular, fine motor coordination. The patient was asked to place nine pegs in nine holes and was scored on the amount of time it took to place and remove all nine pegs.

    Measured: Baseline (Week 0) to Week 12

  16. Nine Hole Peg Test (Nondominant Hand)

    The nine hole peg test was used to assess cognitive function and in particular, fine motor coordination. The patient was asked to place nine pegs in nine holes and was scored on the amount of time it took to place and remove all nine pegs.

    Measured: Baseline (Week 0) to Week 12

  17. Choice Reaction Time Test- Reaction Time

    The choice reaction time test was used to assess cognitive functioning. On random presentation of one of six signal lights, the patient was asked to respond as quickly and accurately as possible by removing their index finger of the dominant hand from the bottom key and pressing whichever of the top six keys was indicated by the signal. Reaction time was the time elapsed between the presentation of the stimulus and the release of the finger and movement time was defined as the time elapsed between release of the finger and pressure of the second key.

    Measured: Baseline (Week 0) to Week 12

  18. Choice Reaction Time Test- Movement Time

    The choice reaction time test was used to assess cognitive functioning. On random presentation of one of six signal lights, the patient was asked to respond as quickly and accurately as possible by removing their index finger of the dominant hand from the bottom key and pressing whichever of the top six keys was indicated by the signal. Reaction time was the time elapsed between the presentation of the stimulus and the release of the finger and movement time was defined as the time elapsed between release of the finger and pressure of the second key.

    Measured: Baseline (Week 0) to Week 12

  19. Visual Assessment Scale (VAS) of Global Impression - Patient

    The VAS used a 10-cm scoring scale in which values were reported in mm such that 0=bad and 100=good. Total score range on VAS is from 0 to 100.

    Measured: Baseline (Week 0) to Week 12

  20. Visual Assessment Scale (VAS) of Global Impression - Parents

    The VAS used a 10-cm scoring scale in which values were reported in mm such that 0=bad and 100=good. Total score range on VAS is from 0 to 100.

    Measured: Baseline (Week 0) to Week 12

  21. Visual Assessment Scale (VAS) of Global Impression - Investigator

    The VAS used a 10-cm scoring scale in which values were reported in mm such that 0=bad and 100=good. Total score range on VAS is from 0 to 100.

    Measured: Baseline (Week 0) to Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing EGb 761 120 mg in people with Friedreich Ataxia, run by Ipsen at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 May 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Creatine Rephosphorylation Rate Post Exercise (time frame: Baseline (Week 0) to Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Apr 2020.
