FDA Lifts Partial Hold on MacroGenics' LINNET Study of Lorigerlimab

  • FDA removed the partial clinical hold on MacroGenics’ Phase 2 LINNET study of lorigerlimab, a bispecific DART® molecule targeting PD-1 and CTLA-4.
  • Enrollment in the study will resume under a revised protocol with additional risk-mitigation measures for hematologic and cardiac toxicities.
  • The LINNET study evaluates lorigerlimab in up to 60 patients with platinum-resistant ovarian cancer (PROC) or clear cell gynecologic cancer (CCGC).
  • MacroGenics plans to provide a mid-2026 clinical update on the program.

The FDA's decision to lift the partial clinical hold on the LINNET study is a critical milestone for MacroGenics, allowing the company to advance its bispecific antibody candidate, lorigerlimab. This development comes at a time when the biopharmaceutical industry is increasingly focused on innovative cancer therapies targeting immune checkpoints like PD-1 and CTLA-4. The success of this program could position MacroGenics as a key player in the gynecologic oncology space, provided it can demonstrate both efficacy and safety in upcoming clinical updates.
