Ultragenyx's DTX401 Gene Therapy Progress Drives Buy Rating Amid Promising Market Potential

Ultragenyx's strategic progress with DTX401 gene therapy has driven a Buy rating from Leerink Partners analyst Joseph Schwartz. The company has initiated a rolling Biologics License Application to the FDA and has shown promising results in reducing daily cornstarch intake for GSDIa patients. The potential market size for the therapy is estimated at around $460 million in the US and EU, with a 60% probability of success.

Ultragenyx Pharmaceutical has made significant strides in its development of DTX401, an AAV gene therapy for Glycogen Storage Disease Type Ia (GSDIa), by initiating a rolling Biologics License Application (BLA) submission to the U.S. Food and Drug Administration (FDA). The company's strategic move comes on the heels of promising results from Phase 3 studies, which demonstrated a substantial reduction in daily cornstarch requirements for GSDIa patients.

The rolling submission allows the FDA to begin reviewing the non-clinical and clinical modules of the BLA while Ultragenyx completes the chemistry, manufacturing, and controls (CMC) module, expected by the fourth quarter of 2025. The submission includes data from a 96-week Phase 3 study, showing a 60% reduction in cornstarch requirements for the ongoing DTX401 group and a 64% reduction for the crossover placebo group [1].

Ultragenyx's proactive approach to addressing potential regulatory hurdles is evident in its incorporation of lessons learned from its previous UX111 program. By resolving manufacturing facility observations and other related FDA observations, the company aims to expedite the regulatory review process and increase the likelihood of first-cycle approval [2].

The potential market size for DTX401 is estimated at around $460 million in the US and EU, with a 60% probability of success. Successful approval and commercialization of DTX401 could significantly enhance Ultragenyx's revenue streams and market position in the rare disease sector. However, investors should be cautious of potential risks and uncertainties associated with the regulatory approval process [3].

Leerink Partners analyst Joseph Schwartz has given Ultragenyx a Buy rating, acknowledging the company's strategic progress with DTX401. The analyst's assessment reflects the promising clinical data and the company's proactive approach to resolving regulatory hurdles [4].
