In preclinical studies for our lead program in FA, we have observed restoration of frataxin (FXN) levels in multiple cell types from FA patients and anin vivo murine model of FA using our FA GeneTAC® molecules. At doses that were observed to be well-tolerated in rodents and non-human primates (NHPs), FA GeneTAC® molecules achieved biodistribution to brain and heart, key organs affected by FA, at concentrations that exceeded those observed to restore FXN levels in FA patient cells. Further, and consistent with this favorable target-organ biodistribution, we observed increased endogenous FXN expression in the brain and heart in an animal model of FA after treatment with our FA GeneTAC® molecules. In February 2022, the Investigational New Drug Application (IND) for our lead FA GeneTAC® small molecule, DT-216, formulated as the prior DT-216 product candidate, was cleared by the U.S. Food and Drug Administration (FDA) to commence Phase 1 clinical trials. In December 2022, we reported positive initial data from the Phase 1 single-ascending dose (SAD) clinical trial and in August 2023, we reported data from the Phase 1 multiple-ascending dose (MAD) clinical trial of the prior DT-216 product candidate. Both studies showed that DT-216 was generally well-tolerated and exhibited the ability to overcome the FXN transcription impairment that causes FA in FA patients. Data from the Phase 1 MAD clinical trial suggests more sustained exposure is likely needed to achieve a more durable increase in FXN expression, and we observed five cases of injection site thrombophlebitis in the Phase 1 MAD clinical trial. We then shifted focus to developing DT-216 with a potentially improved formulation to enable higher exposure and chronic administration for treatment of FA. These efforts resulted in a new product candidate, DT-216P2, which uses the same drug substance, DT-216. In nonclinical studies, we observed higher and more sustained DT-216 plasma levels after administration of DT-216P2 than was seen in studies with the prior DT-216 product candidate. Additionally, we observed favorable injection site tolerability following multiple intravenous (IV) administrations of DT-216P2.

Previous wording

A Phase 1 SAD clinical trial of DT-216P2 in normal healthy volunteers in Australia to evaluate single doses using multiple routes of administration, specifically IV infusion and subcutaneous (SC) injection and infusion routes, has shown that human plasma pharmacokinetics (PK) profiles of DT-216P2 were consistent with NHP data following both IV and SC single-dose administration. Early human PK data has demonstrated that DT-216P2 exhibited improved exposure and PK parameters compared to the prior DT-216 product candidate, including higher AUC and sustained plasma levels at comparable doses.

In June 2025, we received a clinical hold notice from the FDA regarding our IND application for DT-216P2. The FDA’s request pertains to the starting dose in the United States, which we plan to address with clinical data and, if needed, nonclinical data, in order to initiate studies for DT-216P2 in the United States.

Current wording

In June 2025, we received a clinical hold notice from the FDA regarding our IND application for DT-216P2. In December 2025, the clinical hold was lifted and we received clearance from the FDA to initiate clinical studies for DT-216P2.

In December 2022, we nominated our second GeneTAC® small molecule, DT-168, an eye drop for the treatment of FECD. When tested in vitro in FECD patient-derived corneal endothelial cells, our FECD GeneTAC® molecules led to robust reductions in the pathogenic nuclear RNA foci and corrected key mis-spliced transcripts to levels observed in control corneal endothelial cells from unaffected donors. DT-168 was well-tolerated and distribution of DT-168 was observed in and through the cornea in animal models after administration via eye drop. In addition, DT-168 has been evaluated in chronic toxicity studies of up to nine months in duration. We believe these preclinical data support the potential of our novel GeneTAC® small molecules to correct the most common underlying genetic cause of FECD. We are currently conducting an observational study in FECD to confirm disease characteristics and evaluate deterioration in the context of running a trial and to identify characteristics of FECD patients at risk of more rapid disease progression. We have achieved our enrollment goal for the observational study by recruiting and completing baseline assessments on approximately 250 FECD patients. Based on the baseline characteristics data, we have chosen approximately 100 patients for future follow-up visits. This will inform our clinical development efforts and we believe it could potentially increase the probability of DT-168 programmatic success.

In May 2025, we reported results from a completed Phase 1, double-masked, placebo-controlled, randomized, SAD/MAD clinical trial evaluating the safety, tolerability and systemic PK of DT-168 ophthalmic solution in normal healthy volunteers. Twenty-four normal healthy volunteers received either placebo or single- and multiple-ascending doses of DT-168 eye drops twice daily for seven days (up to a maximum dose of two 0.5% drops twice-daily). DT-168 eye drops were well-tolerated in all participants. There were no serious adverse events, no ocular adverse events (AEs) and no treatment discontinuations due to AEs in the trial. All observed AEs were deemed not related to DT-168 by the trial investigator. PK analysis demonstrated systemic exposure below the limit of quantitation for all participants across all timepoints and all dose groups. In parallel with the Phase 1 trial, we conducted reference range studies which showed consistently different splicing in the corneal endothelium between unaffected eye donors and surgical samples from mutant TCF4 FECD patients, supporting the potential for corneal endothelium biomarkers as a clinical proof-of-concept measure of drug activity. We are conducting a Phase 2 biomarker trial of DT-168 to evaluate safety, tolerability, and corneal endothelium biomarkers in patients with FECD. FECD Patients will receive 0.5% DT-168 eye drops twice-daily for approximately four weeks or more before corneal transplant surgery. Following surgery, tissues from the treated eyes of FECD patients will undergo testing to assess corneal endothelium biomarkers including the abnormal splicing of genes known as spliceopathy. We anticipate reporting data from the Phase 2 biomarker trial in the second half of 2026.

In November 2025, we nominated our third GeneTAC® small molecule, DT-818, as a development candidate for the treatment of DM1. The underlying cause of DM1 is a CTG repeat expansion in the DMPK gene, which DT-818 is designed to address by selectively reducing transcription of the mutant expanded allele. In preclinical studies, DT-818 has demonstrated a potential best-in-disease profile for DM1, including a greater than 90% reduction in toxic RNA foci in DM1 patient cells, corresponding splicing correction and selective targeting of mutant DMPK. In preclinical models of DM1 (HSALR mouse model with CTG repeats under the control of the actin promoter), DT-818 treatment resulted in improved myotonia and foci reduction. In tissue distribution studies in NHPs, DT-818 levels were observed to be at expected pharmacologic levels in key target tissues at well-tolerated doses. We have obtained regulatory clearance to initiate clinical development of DT-818 and plan to begin dosing DM1 patients in a Phase 1 MAD trial in Australia to assess safety and correction of mis-splicing in the first half of 2026, with splicing data expected in 2027.
