Design Therapeutics Inc

Previous wording

We are a clinical-stage biopharmaceutical company pioneering the research and development of GeneTACTM molecules, which are a novel class of small-molecule gene targeted chimera therapeutic candidates designed to be disease-modifying by addressing the underlying cause of diseases caused by inherited nucleotide repeat expansion mutations. Certain diseases caused by inherited nucleotide repeat expansion, such as Friedreich ataxia (FA) and fragile X syndrome, can result in reduced gene expression and deficiency of vital proteins; in other diseases, such as myotonic dystrophy type-1 (DM1), Fuchs endothelial corneal dystrophy (FECD), and Huntington's disease (HD), the nucleotide repeat expansions result in the generation of toxic gene products, often associated with pathological nuclear foci and broad splicing disruptions or the expression of mutant proteins that form toxic aggregates. Our GeneTACTM small molecules are designed to selectively target expanded genetic repeat sequences, modulate gene expression either by dialing up or down mRNA transcription, depending on the cause of the disease, and restore cellular health. As a platform, we believe that GeneTACTM molecules have broad potential applicability across currently unaddressed degenerative, monogenic nucleotide repeat expansion diseases affecting millions of individuals worldwide.

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 GeneTACTM molecules. At doses that were observed to be well tolerated in rodents and non-human primates (NHPs), FA GeneTACTM 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 GeneTACTM molecules. In February 2022, the Investigational New Drug Application (IND) for our lead FA GeneTACTM 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 single-ascending dose (SAD) Phase 1 clinical trial showing that DT-216 was generally well-tolerated and exhibited the ability to overcome the FXN transcription impairment that causes FA, with a greater than two-fold increase in FXN mRNA in the cohort with the highest response. These data supported the subsequent advancement of DT-216 in the multiple-ascending dose (MAD) Phase 1 clinical trial of the prior DT-216 product candidate. In August 2023, we reported data from the MAD Phase 1 clinical trial showing that after three weekly intravenous administrations of the prior DT-216 product candidate, DT-216 levels in plasma and skeletal muscle tissue were both transient. This transient exposure was sufficient to lead to an increase in FXN mRNA in tissue, but longer exposure is likely needed to drive sustained increase of FXN mRNA and protein. DT-216 was generally well-tolerated in the MAD study. In patients receiving the prior DT-216 product candidate in the MAD study, we observed five cases of injection site thrombophlebitis, which we believe were attributable to the formulation excipients. We then shifted focus to developing DT-216 with an 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 with DT-216P2 than was seen in studies previously conducted with the prior DT-216 product candidate. Additionally, we observed favorable injection site tolerability following multiple intravenous administrations of DT-216P2. We expect to initiate a SAD Phase 1 clinical trial of DT-216P2 in normal healthy volunteers in the first half of 2025, subject to regulatory clearance. We anticipate that we will begin FA patient dosing later in 2025.

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. A Phase 1 SAD clinical trial of DT-216P2 in normal healthy volunteers is ongoing in Australia to evaluate single doses using multiple routes of administration, specifically IV infusion and subcutaneous (SC) injection and infusion routes. Results from this Phase 1 SAD clinical trial will inform plans for a clinical trial in FA patients, anticipated to begin in mid-2025. We anticipate providing an update in 2026 on the effect of DT-216P2 on endogenous FXN levels following 12 weeks of dosing.

In December 2022, we nominated our second GeneTACTM small molecule, DT-168, an eye drop for the treatment of FECD. When testedin vitro in FECD patient-derived corneal endothelial cells, our FECD GeneTACTM 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. We believe these preclinical data support the potential of our novel GeneTACTM small molecules to correct the most common underlying genetic cause of FECD. We have initiated a Phase 1 clinical trial of DT-168 in normal healthy volunteers, which we expect to complete by year-end, with initial data expected in the first half of 2025. In addition, DT-168 is being evaluated in ongoing chronic toxicity studies of up to nine months in duration. In parallel, we are continuing our ongoing observational study in FECD patients, where we plan to recruit 200 patients to confirm disease characteristics and deterioration in the context of running a trial and to identify characteristics of FECD patients at risk of more rapid disease progression. This will inform our subsequent clinical development efforts and we believe it could potentially increase the probability of DT-168 programmatic success.

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.

Our third program based on the GeneTACTM platform is focused on HD. We are currently conducting preclinical studies on two promising HD GeneTACTM candidate molecules, candidate molecule 1 and candidate molecule 2. We have observed reduced mutant HTT (mtHTT) mRNA and protein and preservation of wild type HTT (wtHTT) in HD patient cells after treatment with our HD GeneTACTM candidate molecules. Inin vivo studies in zQ175DN mice, an animal model of HD, we observed a reduction of over 50% in mtHTT RNA and protein in the brain striatum after eight weeks of systemic administration of our HD GeneTACTM candidate molecules. In the same study, wtHTT mRNA and protein levels were shown to be preserved after treatment with our HD GeneTACTM candidate molecules. Our HD GeneTACTM candidate molecules were shown to be well tolerated in rodents and NHPs in ongoing studies. We believe these data support the potential for our HD GeneTACTM candidate molecules to correct the underlying cause of HD. We plan to continue to evaluate these HD candidate molecules in nonclinical studies and expect to nominate one of them as a development candidate.
