Zenas Bio Pharma – Director, US West Medical Science Liaison (MSL) Manager

Zenas is a clinical‑stage global biopharmaceutical company committed to becoming a leader in the development and commercialization of transformative therapies for patients with autoimmune diseases. Our core business strategy combines experienced leadership with a disciplined product candidate acquisition approach to identify, acquire and develop product candidates globally that we believe can provide superior clinical benefits to patients living with autoimmune diseases.

Zenas is advancing two late‑stage, potential franchise molecules, obexelimab and orelabrutinib. Obexelimab is a bifunctional monoclonal antibody designed to bind both CD19 and FcγRIIb to inhibit the activity of cells involved in many autoimmune diseases without depleting them. Orelabrutinib is a potentially best‑in‑class, highly selective CNS‑penetrant, oral, small‑molecule Bruton’s Tyrosine Kinase (BTK) inhibitor with the potential to address compartmentalized inflammation in Multiple Sclerosis.

Earlier‑stage programs include a preclinical IL‑17AA/AF inhibitor and a preclinical brain‑penetrant TYK2 inhibitor.
