BBT002

Type 2 (T2) inflammatory diseases are characterized by skewed T2 immune responses driven by T2 cytokines including IL-4, IL-13, and IL-5. In specifics, IL-4 and IL-13, acting through IL-4Rα, promote Th2 polarization, IgE production, barrier dysfunction, mucus hypersecretion, and tissue remodeling, while IL-5 sustains eosinophil maturation, survival, and effector damage. These cytokines drive T2 inflammation across the airways, skin, and gut, contributing to diseases such as chronic obstructive pulmonary disease (COPD), asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), food allergy, chronic spontaneous urticaria (CSU), and eosinophilic esophagitis (EoE), and making them key therapeutic targets1. Dual targeting IL-4Rα and IL-5 offers advantages over single targeting of IL-4Rα or IL-5 or upstream alarmin proteins (e.g., TSLP, IL-33) by preventing escape (or “leakage”2) of the downstream T2 cytokines (IL-4, IL-13 and IL-5) and providing complete inhibition of the pathogenic inflammation.

BBT002 blocks the entire spectrum of Type 2 cytokines (IL-4, IL-13, and IL-5) while incorporating Fc mutations that eliminate unwanted effector functions and extend half-life for longer dosing intervals. The dual targeting design positions it to provide more comprehensive benefits over current single targeting therapies across T2 inflammatory diseases, particularly those with significant eosinophilic inflammation, while eliminating the risk of eosinophilia associated with anti-IL-4Rα monotherapy.

BBT001

BBT001 is a bispecific IgG1 antibody for Type 2 inflammatory dermatological conditions. Using a 2+2 format, it simultaneously engages IL-4Rα and IL-31 to deliver faster and synergistic efficacy compared to existing treatments.

The drug incorporates Fc modifications that enhance FcRn affinity and extend half-life, enabling longer dosing intervals.

BBT001’s innovation addresses a critical treatment gap. While targeting IL4/13 tackles the fundamental Th2 inflammatory cascade, it does not effectively reduce IL-31 levels, providing only slow, moderate itch relief. This leaves patients trapped in the destructive “itch-scratch cycle” where continuous scratching compromises skin barrier function and perpetuates inflammation.

BBT001’s direct IL-31 targeting is designed to immediately affect sensory nerves, rapidly reducing itchiness while accelerating skin lesion improvement. This dual-pathway approach promises to break the itch-scratch cycle more effectively than single-target therapies, potentially transforming treatment for Type 2 inflammatory dermatological conditions.
