Allogene Gets 3 Fast Tracks for Cell Therapy

Share

FDA has granted Allogene Therapeutics three fast track designations for ALLO-329, an investigational dual-targeted CD19/CD70 allogeneic CAR T cell therapy. The designations are for treating adults with:

  • active refractory moderate-to-severe systemic lupus erythematous (SLE);
  • active severe/refractory idiopathic inflammatory myopathy (IIM), specifically dermatomyositis, immune mediated necrotizing myopathy and anti-synthetase syndrome; and
     
  • active refractory diffuse systemic sclerosis (SSc).

The company says it expects to initiate a Phase 1 RESOLUTION “basket” trial later this year. A basket trial evaluates a single drug in patients with different types of disease that often share a common biomarker or genetic alteration, according to NIH. The trial design will leverage “clinically validated Dagger technology to drive CAR T cell expansion and prevent rejection, includes two distinct lymphodepletion arms: one using a dose of cyclophosphamide alone, which is used by rheumatologists, and another that eliminates lymphodepletion entirely,” the company says.

ALLO-329 uses CRISPR-based site-specific integration for dual CAR expression, according to Allogene, adding that the approach targets both CD19+ B cells and CD70+ T cells, which play a role in autoimmune disease pathogenesis.
