Diamyd Medical Advances Phase 3 Diabetes Trial by Accelerating Efficacy Readout by Nine Months
This move is critical as it aligns with the FDA’s guidance and emphasizes the urgent need for effective treatment options in type 1 diabetes. The pivotal DIAGNODE-3 trial is designed as a randomized, double-blind, placebo-controlled study, evaluating the response of approximately 300 genetically defined participants.
One standout feature of the DIAGNODE-3 trial lies in its co-primary efficacy endpoints, which include C-peptide area under the curve (AUC) — a marker that indicates the body’s ability to produce insulin — and HbA1c levels, a critical measure for assessing long-term blood sugar control. Originally, these benchmarks were set for evaluation at the 24-month mark, but now they have been shifted to 15 months, with plans for a formal protocol amendment to follow for FDA review.
Even with this expedited timeline, the long-term safety and efficacy will be evaluated at the originally planned 24-month point, which will now serve as a secondary endpoint. This approach ensures that while the team gathers quicker results, they are not skipping any critical evaluation steps that would support the durability of the treatment effect of their leading product, Diamyd®.
Diamyd® itself is an innovative antigen-specific immunotherapy designed to preserve the body’s endogenous insulin production, showcasing an approach to diabetes treatment that aims at long-term management rather than short-term fixes. The FDA has previously recognized the urgency of this treatment path, granting Fast Track Designation for Diamyd across all stages of type 1 diabetes and Orphan Drug Designation for the symptomatic Stage 3 category.
As it stands, the DIAGNODE-3 trial remains on track for its interim efficacy readout, which is due to occur at the end of March 2026, involving approximately 170 participants. The strong outcomes from this trial could potentially support an accelerated Biologics License Application (BLA) pathway, streamlining the process to bring Diamyd® to those who need it most.
The trial is actively recruiting patients from 57 clinics across eight European countries and the United States, specifically targeting individuals carrying a common genetic marker (HLA DR3-DQ2) associated with type 1 diabetes. This population makes up roughly 40% of type 1 diabetes patients in both Europe and the U.S., highlighting the considerable impact that Diamyd Medical’s research could have on patient outcomes. Preliminary results show promise in preserving endogenous insulin production, which could transform how type 1 diabetes is managed.
Additionally, as part of its commitment to these advancements, Diamyd Medical is developing a biomanufacturing facility in Umeå, Sweden, aimed at producing the recombinant GAD65 protein integral to the immunotherapy's formulation.
In summary, the progress made by Diamyd Medical in accelerating its Phase 3 trial efficacy readout reflects a significant leap forward in diabetes research. By working closely with regulatory authorities and utilizing data to guide their processes, they are on track to make meaningful contributions to the treatment landscape for type 1 diabetes. Investors and stakeholders can keep an eye out for the upcoming interim results in March next year, as this could serve as a pivotal moment for both the company and the broader diabetes treatment community.
