Phase 2ADCPDC
In a setback to the growing field of systemic lupus erythematosus drug development, Amgen is bowing out of two Phase IIb trials after deciding its candidates were unlikely to work.
Both trials, involving two different molecules, were stopped for futility, Amgen disclosed in its quarterly report. Rozibafusp alfa (AMG 570) is an antibody-peptide conjugate that targets inducible T cell costimulator ligand (ICOSL) and B-cell activating factor (BAFF) in hopes of hitting both immune cell populations; efavaleukin alfa is an interleukin-2 (IL-2) mutein Fc fusion protein.
