Pipeline and clinical program updates

  • Advancing two clinical-stage autoimmune therapeutics focused on infrequent, self-administered subcutaneous dosing.

  • Claseprubart targets the classical complement pathway with positive phase 2 data in myasthenia gravis (MG) and proof of concept in CIDP and MMN.

  • DNTH212, a bispecific BDCA2 and BAFF/APRIL inhibitor, has started phase 1 trials, showing superior in vitro and NHP data versus competitors.

  • Both programs aim for best-in-class efficacy, safety, and patient convenience.

  • Phase 3 for claseprubart in MG to include every-two-week and every-four-week dosing arms.

Efficacy, safety, and differentiation

  • Claseprubart demonstrated robust, rapid, and statistically significant efficacy in MG, with potential for superior efficacy over C5 inhibitors.

  • Open-label extension data support equivalent efficacy for monthly dosing.

  • No Box warning or REMS program anticipated, differentiating from other complement inhibitors.

  • Head-to-head in vitro data show claseprubart is more potent than riliprubart and empasiprubart.

  • DNTH212 aims for enhanced efficacy in diseases driven by both innate and adaptive immunity, with no new safety signals expected.

Market opportunities and competitive landscape

  • Targeting over 150,000 patients in the US across MG, CIDP, and MMN.

  • MMN market is small but offers blockbuster potential due to lack of competition and high pricing.

  • Only one other biologic (empasiprubart) is being studied in MMN; claseprubart is more potent and more convenient.

  • Competitors like Argenx and Sanofi are running head-to-head trials versus IVIG, signaling belief in complement inhibition's potential.

  • DNTH212 will prioritize indications such as SLE, dermatomyositis, or Sjogren’s, with updates expected in the first half of the year.

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.
