Clinical Trials

Fenebrutinib has been evaluated in multiple clinical trials spanning Phase 1, Phase 2, and Phase 3 studies sponsored primarily by Hoffmann-La Roche and Genentech Inc., with recruitment statuses including recruiting, active not recruiting, completed, and terminated. These studies target healthy participants, hematologic malignancies such as chronic lymphocytic leukemia and diffuse large B-cell lymphoma, and autoimmune conditions including multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, and chronic urticaria. Additionally, several clinical trials focus on late-phase evaluations in relapsing multiple sclerosis, primary progressive multiple sclerosis, and urticaria.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Fenebrutinib selectively binds to Bruton's tyrosine kinase in a non-covalent manner, blocking downstream B-cell receptor and Fc receptor-mediated signaling pathways. This enzymatic inhibition suppresses B-cell activation, proliferation, and proinflammatory mediator release, providing the biological mechanism for evaluating its clinical efficacy in autoimmune conditions such as multiple sclerosis and systemic lupus erythematosus.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
