The Bottom Line
• Every ataxia patient must participate in
clinical trials.
• Every researcher designing a clinical trial
must make it accessible to all ataxia
patients.
• There will be exceptions to both of these
fiats, but they must be justified.

TYPES OF CLINICAL TRIALS
TYPE
# SUBJECTS LENGTH
AIM OF STUDY
N of 1
1
Ongoing
Do I get better or stop getting
worse on this drug?
Pilot
Up to 20
All get drug
Weeks to
months
Is a larger study worth doing,
will there be problems?
Phase 1
20-80 normal or patient
in groups of 3
All get drug
2 years
Escalating doses to learn side
effects, safety, best dose
Phase 2
20-300
Placebo and
drug groups
Compassionate
trials do not use
placebo.
2 years
To assess potential for good
effects, as well as side effects.
Also designed as “futility”
study—to show a drug doesn’t
not work(fewer subjects, less$)
Phase 3
300-3000
Placebo and
drug groups
3-5 years
To prove efficacy
May include crossover design,
open extension trial
Phase 4
100’s-1000’s
Open drug use
Ongoing
To find out more about the
effects of an approved drug.
Every Ataxia Patient Must Participate in
Clinical Trials
1. Registries will enable you to be found.
These are rare diseases with very small
numbers of patients who can participate.
Every person counts.
2. Be knowledgeable about what makes a good
clinical trial—don’t make bad investments.
3. Speak up about the roadblocks to participation.
Become involved in planning the trials.
4. Be prepared to make sacrifices.

Every Researcher Designing A Clinical
Trial Must Make It Accessible To All
Ataxia Patients.
• Design trials that can use the fewest patients over the
shortest period of time (this usually means testing better
drugs and using biomarkers).
• What is the rationale for excluding certain patients? Can
those excluded be used in other ways? Parallel or
compassionate studies?
But remember that a patient can participate in only one
trial at a time and that participation in some trials may
permanently disqualify participation in others.
• Reimbursing travel costs is essential for recruitment and
compliance. Telemedicine?
• Don’t expect the patients to make unreasonable
sacrifices.

Registries
• Ataxia patients are some of the most
highly motivated research subjects
around, but they aren’t superhuman.
• The Cooperative Ataxia Research Network
and the National Ataxia Foundation are not
mind-readers.
• Every ataxia patient must be in a Registry.

CINCH
for episodic ataxias
• http://rarediseasesnetwork.epi.usf.edu/cinch/index.htm
• CINCH
• Clinical Investigation of Neurologic Channelopathies
• is a collaborative effort of doctors, patient
organizations, and federal health agencies that
want to learn more about these diseases so that
ultimately they can offer better treatments to
patients.

Friedreich’s Ataxia Registry
•
http://www.curefa.org/registry.html
•
The FARA patient registry is the only worldwide registry of Friedreich’s ataxia patients. This
registry currently holds the demographic and clinical information on >1200 Friedreich’s ataxia
patients from across the United States and internationally. This registry was created to serve the
patient, physician, and research communities.
For the Patient Community
Participation in the FARA patient registry ensures that patients are informed about opportunities to
participate in clinical research studies and kept up-to-date on the progress of clinical trials.
For the Physician
The homepage of the FARA patient registry website, www.curefa.org/registry, is a place that you
can go to find an up-to-date listing of ongoing clinical trials for FA. You can refer your FA patients
to the patient registry so that he/she can consider registering. FARA can provide you with registry
brochures that you can give your patients to assist with the referral process.
For the Researcher
The FARA patient registry is a patient recruitment and communications tool for both academic and
industry sponsored clinical research studies and trials. The registry coordinator can perform
queries based on the inclusion/ exclusion criteria of a study and send patients information about a
study for which they qualify. Patients can be contacted by the registry coordinator via e-mail, mail,
or by telephone. Informational postings can also be added to the registry homepage as well as the
FARA website and in the FARA newsletter. FARA is committed to assisting researchers with study
recruitment and participation.

Roadblocks for Clinical Researchers
• Picking the right drugs.
• Designing the trial properly—number of patients,
measures/biomarkers, length of study, placebo,
how many sites.
• Getting the FDA to agree.
• Getting funding.
• Finding sites and getting them approved.
• Finding subjects.
• Doing the work in a timely fashion.

PRO’S AND CON’S OF CANDIDATE
DRUGS FOR HUMAN TRIALS
• Rationale--do we expect it to work? Basic Science
• Efficacy-has it worked in well-designed
animal or pilot human trials?
• Safety-has safety been proven?
• Do the anticipated benefits outweigh the
possible risks?
• Availability--designer drugs vs. already
available ones. What’s in it for the drug
company?
• Cost (and where to get the money from)

OFFICIAL PIPELINE FOR NEW DRUGS
Up to 15 years and $500-700million
to get to market
•
•
Discovery—clinicians and
scientists working out the cause of
the disease, the “dominos” that fall
over, and targeted candidate drugs.
Preclinical testing—test tube and
animal studies.
Phase I—dosing, safety
•
Phase II—safety, possible efficacy
•
•
•
Phase III—efficacy
FDA Approval
Phase IV--Post-marketing studies
for long-term side-effects and good
effects.
•
To help with promising drugs for serious
diseases with unmet needs:
NIH—Rapid Access to Intervention Development
(RAID)
FDA—Orphan Drug Status

EFFICACY--CAN WE SHOW THAT THE DRUG
ACTUALLY MAKES A DIFFERENCE?
• Symptomatic benefit vs. disease-modifying
• Is the candidate drug strong and specific?
• How much does the disease change over
how much time? Natural history.
• How accurately can this change be
measured? Rating scales, QOL measures.
• Can biomarkers show clinically meaningful
change quicker? 1° vs. 2° outcome measure.
• Can enough researchers and patients be
found? Research centers and registries.
