The brief
- AbbVie generates $61 billion annual revenue and is known for Humira and Botox.
- Chairman and CEO Robert Michael has led the company since July 2024, with board promotion in March 2026.
- Capstan acquisition in June 2025 brought CPTX2309, an in vivo CAR-T therapy in Phase 1 trials for B cell-mediated autoimmune diseases.
Technical approach
Cell engineering in the bloodstream
CPTX2309 delivers CAR mRNA directly to CD8+ T cells, avoiding ex vivo manufacturing and lymphodepleting chemotherapy.
Immune system reprogramming
Transient anti-CD19 CAR expression depletes autoreactive B cells while allowing healthy populations to regenerate, resetting tolerance.
Treatment of B cell-mediated disease
Initial indications focus on autoimmune diseases driven by B cells, such as lupus, rheumatoid arthritis variants, and vasculitis.
