Disc Medicine Plans Accelerated NDA Submission for Bitopertin

Disc Medicine Moves Forward with Bitopertin Development

Disc Medicine, Inc. (NASDAQ:IRON), a dedicated biopharmaceutical company, is making significant strides in its efforts to provide revolutionary treatments for individuals suffering from serious hematologic diseases. Recently, the company announced vital outcomes from a Type C meeting held with the U.S. Food and Drug Administration (FDA) regarding bitopertin, a promising investigational therapy aimed at treating Erythropoietic Protoporphyria (EPP).

Accelerated Approval Pathway for Bitopertin

In the competitive landscape of biopharmaceutical innovations, obtaining regulatory acknowledgment for treatment pathways is crucial. Disc Medicine is actively pursuing accelerated approval for bitopertin, focusing on protoporphyrin IX (PPIX) reduction as a surrogate endpoint. This approach positions Disc Medicine well within the FDA's expedited review processes, emphasizing the urgency and importance of their therapeutic interventions.

Plans for NDA Submission

The company plans to submit a New Drug Application (NDA) under an accelerated approval pathway by the latter half of 2025, a timeline that relies heavily on existing clinical data gathered from pivotal studies like the BEACON and AURORA Phase 2 trials. There is high anticipation among stakeholders as the NDA submission draws nearer, representing a significant milestone in the company’s journey to bring this innovative therapy to market.

Regulatory Collaboration and Trial Design

During the Type C meeting, Disc Medicine received positive feedback from the FDA on its proposed design for the APOLLO post-marketing confirmatory trial. This collaboration serves as a testament to the alignment between Disc Medicine and the regulatory body, strengthening their plans going forward. The trial is expected to commence mid-2025 and includes strategic endpoints aimed at gauging the efficacy and safety of bitopertin.

Key Features of the APOLLO Trial

The upcoming APOLLO trial incorporates several critical components that highlight its design's thoroughness and intent:

• The co-primary endpoints will measure both the average monthly total time patients can tolerate sunlight without pain and the percent change from baseline in whole blood metal-free PPIX levels post-treatment.
• Additional efficacy measures will include the incidence of phototoxic reactions, total pain-free time, and patient subjective improvements.
• The trial plans to employ a double-blind, placebo-controlled approach, with approximately 150 participants.
• Patients aged 12 and older with EPP will be included, broadening the potential impact of the study.

Importance of Bitopertin in EPP Treatment

Bitopertin offers a novel approach to addressing the challenges posed by EPP, a rare disease characterized by painful sensitivity to sunlight. Through its mechanism as an orally administered inhibitor of glycine transporter 1 (GlyT1), bitopertin has the potential to significantly improve the quality of life for patients affected by this condition.

The ongoing development of bitopertin is not just about regulatory approval; it's about delivering tangible improvements in patients' lives. EPP is a debilitating disorder, and there is currently no cure available, with only one FDA-approved treatment, Scenesse® (afamelanotide), currently on the market. Therefore, the introduction of bitopertin could provide a much-needed disease-modifying therapeutic option.

Future Directions for Disc Medicine

With its focused approach toward innovation, Disc Medicine is set to make a notable mark within the biopharmaceutical industry. The anticipated NDA submission in 2025 signals the firm’s ongoing commitment to advancing treatments for conditions like EPP. As the company gears up for trial initiation and further regulatory interactions, the support and engagement of the patient community, as well as other stakeholders, will play an integral role in their success.

For stakeholders and community members interested in the developments of Disc Medicine and bitopertin, management will be hosting an informative conference call to share updates and address inquiries surrounding these promising advancements.
