Dianthus Therapeutics Achieves Promising Trial Results for DNTH
Dianthus Therapeutics Reports Encouraging Results from Phase 2 Trials
Dianthus Therapeutics Inc. (NASDAQ: DNTH) has unveiled positive topline data from its Phase 2 MaGic trial, which assesses the safety and effectiveness of claseprubart (DNTH103) in adults diagnosed with acetylcholine receptor antibody-positive generalized myasthenia gravis (gMG).
Impressive Trial Outcomes
The results displayed that both the 300mg and 600mg doses of claseprubart led to rapid, statistically significant, and meaningful improvements when contrasted with the placebo. Measurements derived from the Myasthenia Gravis Activities of Daily Living (MG-ADL) and the Quantitative Myasthenia Gravis (QMG) scales indicated substantial enhancements starting from the first week and persisting through the thirteenth week.
Detailing the MG-ADL Improvements
For the 300mg dosage, patients showed a significant mean improvement of 4.6 points in the MG-ADL score at Week 13, with a placebo-adjusted improvement of 1.8 points (P=0.0113). Notably, improvements were observable as early as Week 1.
The 600mg dosage yielded an even more impressive mean improvement of 5.4 points in MG-ADL scores by Week 13, translating into a placebo-adjusted enhancement of 2.6 points. Improvement metrics also surfaced swiftly, emerging by the end of the first week.
QMG Results Affirming Disease Severity Reduction
In terms of disease severity measured through the QMG score, claseprubart at the 300mg dosage demonstrated a mean improvement of 4.4 points from baseline at Week 13 (placebo-adjusted increase of 2.4; P=0.0144), with a similar significant uptick noted from Week 1.
The 600mg group recorded a 4.5 point improvement in QMG scores at Week 13 (placebo-adjusted increase of 2.5; P=0.0111), further affirming the compound's efficacy early on as well.
Safety Profile and Tolerability
Overall, claseprubart was reported to be well tolerated, with no serious adverse events related to the drug. The safety profile associated with the drug was comparable to the placebo, indicating no notable treatment-associated serious bacterial infections or symptoms related to emergent autoimmune conditions.
Anticipating Future Developments
Looking ahead, Marino Garcia, President and CEO of Dianthus Therapeutics, noted, "The year 2026 is poised to be rich with catalysts, featuring the launch of the Phase 3 gMG trial and subsequent results from the interim responder analysis of the Phase 3 CAPTIVATE trial targeting Chronic Inflammatory Demyelinating Polyneuropathy, along with topline results from the Phase 2 MoMeNtum trial in Multifocal Motor Neuropathy expected in the second half of ‘26.”
Analyst Ratings and Public Response
An analyst, Myles R. Minter from William Blair, recently stated, "The recent data from the MaGic trial highlights a significant proof of concept for Dianthus's drug pipeline, particularly with claseprubart, which has potential applications across various autoimmune neurology disorders." He expressed heightened confidence regarding upcoming data from both the CAPTIVATE interim readout and the MoMeNtum trial. Furthermore, William Blair maintains an Outperform rating for Dianthus, buoyed by the promising MaGic trial results.
Current Market Performance of DNTH
On the market front, Dianthus Therapeutics shares exhibited a notable increase of 12.28%, priced at $29.75 at the time of reporting.
