To evaluate the safety and tolerability of single ascending doses of CTI-1601 in participants with Friedreich's ataxia
Single Ascending Dose (SAD), Double-Blind, Placebo Controlled Study.

To evaluate the safety and tolerability of single ascending doses of CTI-1601 in subjects with Friedreich's ataxia.

Secondary Objectives:

To evaluate the pharmacokinetics (PK) of CTI-1601 following increasing single doses of subcutaneously (SC) administered CTI-1601.
To evaluate the pharmacodynamics (PD) of CTI-1601 following increasing single doses of SC administered CTI-1601.

Criteria 

Inclusion Criteria:

Subject has genetically confirmed Friedreich's ataxia diagnosis, homozygous GAA repeat expansions, with repeat sizing (if available) included on diagnostic report.
Subject is male or female, 18 years of age or older at screening.
Subject must have a mFARS_neuro score ≥ 20 and be able to traverse a distance of 25 feet with or without some assistive device (cane, walker, crutches, self-propelled wheelchair) and (a) be able to sit upright with thighs together and arms crossed without requiring support on more than two sides; (b) be able to transfer from bed to chair independently or with minimal assistance if, in the opinion of the investigator, the degree of physical disability does not result in undue risk to the subject while participating in the study; and (c) perform basic daily care, such as feeding themselves and personal hygiene, with minimal assistance.
Subjects must weigh > 40 kilograms (kg).

Exclusion Criteria:

Subjects who are confirmed as compound heterozygous (GAA repeat expansion on only one allele) for Friedreich's ataxia.
Subject requires use of amiodarone.
Subject used erythropoietin, etravirine, or gamma interferon within 3 months prior to screening.
Subject use of investigational drug (other than CTI-1601) or device within 90 days prior to screening.
Subject use of daily biotin supplementation that exceeds 30 mcg/day, either as part of a multivitamin or as a standalone supplement, within 7 days prior to study drug administration and/or throughout the entire study.
Subject has clinically significant arrhythmia on electrocardiogram (ECG), or evidence of predisposition to significant ventricular arrhythmia on ECG, or evidence of active and unstable coronary artery disease.
Male subject who has an ECG QTcF > 450 milliseconds or female subject who has an ECG QTcF > 470 milliseconds.
Subject has a screening echocardiogram ejection fraction <45 percent.
Subject has a history of aspiration, aspiration pneumonia, or recurrent episodes of pneumonia (greater than or equal to 2 episodes of pneumonia) within the last 12 months.
Subjects with known or suspected chronic use of cannabinoid products.
