Late-Breaking Oral Presentation

SID Presentations Highlight Immunologic and Clinical Features of Soquelitinib

Novel MOA

Oral Administration

Highly selective ITK inhibition; blocks multiple cytokines and rebalances

immune response

Oral dosing in markets dominated by injectables

Clinical Stage Pipeline in a Product

Safety/efficacy seen in placebo-controlled Phase 1 AD; enrolling Phase 2 AD with registration Phase 3 PTCL ongoing

Broad expansion potential across immune diseases (dermatology, pulmonology, GI and rheumatology)

Strong IP

Proven Management

Composition of matter protection through 2042

Experienced leadership team (rituximab and ibrutinib)

First-in-Class Immune Modulators with Broad Opportunity in Immune Disease
