Guggenheim Securities Emerging Outlook: Biotech Summit 2026 summary12 Feb, 2026

Key developments and pipeline updates

  • 2025 marked a transformational year with positive phase 2 data in myasthenia gravis and the in-licensing of DNTH212, a bifunctional fusion protein targeting BDCA2 and BAFF/APRIL.

  • Two clinical-stage products are advancing: clasiprubart (lead program) and DNTH212, with major catalysts expected in 2026 for CIDP and MMN indications.

  • DNTH212's next steps include announcing three target indications in the first half of 2026 and reporting top-line results from a healthy volunteer study in the second half of 2026.

CIDP program and clinical trial strategy

  • The phase 3 Captivate study in CIDP is progressing ahead of schedule, with interim responder analysis for the first 40 patients expected in Q2 2026.

  • Efficacy benchmarks are set to match or exceed riliprubart, aiming for a 40%-50% responder rate and potentially reducing the trial's higher dose arm for efficiency.

  • The trial design allows refractory patients and uses a rapid switch from IVIG, differentiating it from previous studies and aiming for broader applicability.

  • If efficacy is confirmed, the program could neutralize competitors' time-to-market advantage and support strong market positioning.

MMN and MG program differentiation

  • MMN program aims for similar or superior efficacy to empasiprubart, with advantages in dosing (subcutaneous auto-injector) and safety (no box warning expected).

  • Potency data suggest the product is significantly more potent than empasiprubart, with ongoing studies to confirm if this translates to higher efficacy.

  • MG program phase 2 data showed robust efficacy, especially in more severe patients, and phase 3 will implement stricter screening to control placebo response.

  • Once-a-month dosing is being tested, leveraging long half-life and strong efficacy at lower inhibition levels.

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.
