Strategic focus and pipeline overview

  • Advancing two autoimmune therapeutics, claseprubart and DNTH212, each with best-in-class, pipeline-in-a-product potential targeting infrequent, patient-friendly self-administration.

  • Claseprubart is a potent classical pathway inhibitor with clinical proof-of-concept in gMG, CIDP, and MMN, aiming for convenient subcutaneous dosing every 2 or 4 weeks.

  • DNTH212 is a bifunctional BDCA2 and BAFF/APRIL inhibitor, showing superior in vitro efficacy and targeting both innate and adaptive immune systems.

  • Strong financial position with ~$525M in cash, providing runway into 2028 to fund multiple near-term catalysts.

  • Key upcoming milestones include multiple Phase 3 and Phase 2 trial initiations and readouts for both assets through 2026.

Claseprubart clinical data and market opportunity

  • Phase 2 MaGic trial in gMG showed rapid, sustained, and statistically significant improvements in MG-ADL, QMG, MGC, and MG-QOL-15r scores versus placebo.

  • Over 60% of patients on 300mg/2mL achieved ≥5-point improvement in MG-ADL and QMG; 37% achieved minimal symptom expression at week 13.

  • Safety profile was favorable, with no serious infection signals, no autoimmune activation, and no boxed warning or REMS anticipated.

  • Targeting a large, underpenetrated U.S. gMG market (>100,000 patients), with <20% currently treated with biologics and a market size >$3.5B.

  • Phase 3 trial to include Q4W dosing and refined screening criteria, aiming to further differentiate on efficacy and convenience.

Expansion into CIDP and MMN

  • CIDP market (>40,000 U.S. patients) has high unmet need; active C1s inhibition validated by riliprubart, but claseprubart offers superior potency and more convenient dosing.

  • Phase 3 CAPTIVATE trial in CIDP includes open-label and randomized withdrawal design, with interim responder analysis expected in Q2'26.

  • MMN market (~10,000 U.S. patients) is underdiagnosed; classical pathway inhibition validated, and claseprubart aims to become new standard of care with low-volume, self-administered dosing.

  • Phase 2 MOMENTUM trial in MMN is ongoing, with top-line data expected in 2H'26.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
