Why It Matters

• Breakthrough Therapy Designation is an FDA program meant to speed development and review for therapies addressing serious conditions with preliminary clinical evidence of substantial improvement over existing treatments; designation can increase regulatory interaction and priority review opportunities.
• For investors, the designation is a material regulatory milestone that may increase the program’s visibility and de-risk certain aspects of the development pathway, though it is not an approval and does not guarantee safety, efficacy, or future regulatory success.
• The posted investor presentation and press release provide the company’s public materials and messaging on the development program for stakeholders evaluating Larimar’s clinical and regulatory progress.
