Caused by genetic defect resulting in low levels of frataxin Patients with FA only produce ~20-40% of normal frataxin levels depending on the tissue, sampling technique, and assay considered1 Affects ~20,000 patients globally, with ~5,000 patients in the U.S. and majority of the remaining patients in the EU Approximately 70% of patients present before age 14 Initial symptoms may include unsteady posture, frequent falling and progressive difficulty in walking. By the time symptoms occur, heart damage may have already occurred. Progressive disease: symptoms worsen and patients are eventually confined to a wheelchair with speech becoming hesitant and jerky (often referred to as “scanning of speech”) Life expectancy of 30-50 years Early death usually caused by heart disease No approved therapies available Current treatment options are limited to symptom management Friedreich’s Ataxia (FA) Rare and Progressive Disease 5 1.

CTI-1601 appears to be generally well tolerated at doses up to 100 mg administered daily for 13 days Phase 1 Top-line Data Demonstrated POC for CTI-1601 in FA Daily dosing of CTI-1601 resulted in dose-dependent increases in FXN levels from baseline compared to placebo controls in all evaluated tissues Pharmacokinetic analyses support evaluating a once-daily dosing regimen for CTI-1601 Daily subcutaneous (SC) administration of 50mg and 100mg doses of CTI-1601 resulted in FXN levels in buccal cells that are at, or in excess of, those we would expect to see in phenotypically normal heterozygous carriers (who have FXN levels of ~50% of unaffected persons) Pharmacodynamics Safety Pharmacokinetics Conclusion 8 POC: Proof-of-concept

FDA cleared Phase 2 study’s initiation following review of clinical and non-clinical data SUMMARY OF MULTIPLE-ASCENDING DOSE (MAD) TRIAL SAFETY DATA Repeated SC injections of CTI-1601 appear to be generally well tolerated at doses up to 100 mg administered daily for 13 days. No serious adverse events (SAEs), important medical events, or treatment-related severe adverse events were observed. Most common AEs were mild and moderate injection site reactions (ISR). At least one ISR was seen in 43% of patients receiving placebo, and all patients receiving CTI-1601 experienced ISRs. Most ISRs resolved within an hour after injection, and all ISRs resolved without intervention. There were no study discontinuations due to ISRs. Except for ISRs, the number and severity of AEs did not increase with increasing exposure to CTI-1601. Accumulation of CTI-1601 was not observed at the doses and dose regimens studied. Clinical & Non-clinical Safety Data Support Initiation of the 4-Week, Phase 2 Dose Exploration Study’s 25 mg Cohort The clinical hold was put in place following deaths that occurred during the 26-week toxicology study in 3 out of a total of 34 NHPs. All 3 of these NHPs were in the two highest dose groups. All NHPs in the two lower dose groups survived to the end of the 26-week toxicology study. Based on AUC, Cmax, and Ctrough from the Phase 1 studies at the 25 mg and 50 mg levels, and the no observed adverse effect levels from the 4-, 13-, and 26-week toxicology studies, the safety margins calculated for CTI-1601 are generally greater than 10. Though the precise mechanism of toxicity in NHPs was not determined, we believe the toxicity was associated with accumulation and high levels of exposure as demonstrated by the safety margins. We believe the presence of persistent edema at the injection sites in some NHPs may explain the accumulation associated with adverse events, as well as higher plasma levels of CTI-1601. In the clinic, injection sites will be closely monitored and we intend to avoid the use of injection sites where persistent edema is present. SUMMARY OF NON-HUMAN PRIMATE (NHP) DATA SC: Subcutaneous
Upcoming CTI-1601 Trials Future Planned Trials Include: Global double-blind placebo-controlled pivotal trial. Jive OLE trial for eligible patients who participated in SAD, MAD, and/or four-week dose exploration studies. Expected to begin in 2H 2023. MAD trial in patients 2 to 17 years of age. Participants eligible to screen for Jive OLE trial. Expected to begin in 2H 2023. Phase 2, four-week dose exploration study intended to identify dose and dose regimen for long-term studies. Expected to begin in Q4 2022. *Dose escalation in the Phase 2 trial and initiation of the Jive, pediatric MAD trials and global pivotal trial will be subject to the FDA lifting the partial clinical hold. OLE: Open-label extension
Summary: CTI-1601 Advancing to Phase 2 Trial 15 POC: Proof-of-concept Clinical POC Data Designed to address the root cause of Friedreich’s ataxia by delivering mature FXN to mitochondria. CTI-1601 Daily dosing of 50 mg or 100 mg of CTI-1601 for at least 7 days resulted in buccal cell FXN levels that met or exceeded those expected in phenotypically normal heterozygous carriers. Next Steps Initiate in Q4 2022 a Phase 2 dose exploration study in Friedreich’s ataxia patients. Cohort 1 to evaluate 25 mg dose; dose escalation contingent on FDA review of cohort 1 data. Top-line data from both cohorts expected in 2H 2023.

CTI-1601 Delivers hFXN to Mitochondria in KO Mice hFXN concentration within mitochondria increases in a dose-dependent manner Given subcutaneously, CTI-1601 functionally replaces hFXN in mitochondria of KO mice Succinate dehydrogenase (SDH) activity, which is indicative of mitochondrial function, increases in a dose-dependent manner after administration of CTI-1601; activity plateaus at 30 mg/kg and is equivalent to activity in wild type animals Demonstrated normalization of gene expression in cardiac tissue MPK = mg/kg MPK = mg/kg Normalized Mitochondrial FXN (Heart) Normalized SDH Activity (Muscle)
CTI-1601 Prevents Left Ventricle Dilation in KO Mice Left ventricular (LV) volume increases in systole in untreated mice by 8 weeks (after 4 weeks of dosing with vehicle), but remains similar to wildtype when treated with CTI-1601 (10 mg/kg every other day) CTI-1601-treated mice have similar LV volume as healthy controls; echocardiogram shows significant differences between vehicle and CTI-1601 treated (10 mg/kg every other day) KO mice Diameter (mm) Age in Weeks Age in Weeks Volume (μL) KO: CTI-1601 Wild-type: Vehicle KO: Vehicle Left Ventricle Internal Diameter (Systole) Left Ventricle Volume (Systole)
CTI-1601 Preserves Left Ventricle Function in KO Mice Left ventricular (LV) function drops significantly in vehicle treated mice by week 8 CTI-1601-treated (10 mg/kg every other day) mice have similar LV as healthy controls; echocardiogram shows significant differences between vehicle and CTI-1601 treated KO mice Percent Change Age in Weeks KO: CTI-1601 Wild-type: Vehicle KO: Vehicle Left Ventricle Ejection Function Left Ventricle Fractional Shortening Percent Change Age in Weeks
