ROCKVILLE, Md., May 13, 2025 (GLOBE NEWSWIRE) -- MacroGenics, Inc. (NASDAQ: MGNX), a clinical-stage biopharmaceutical company focused on discovering, developing, manufacturing and commercializing innovative antibody-based therapeutics for the treatment of cancer, today provided an update on its recent corporate progress and reported financial results for the quarter ended March 31, 2025.

“In the first quarter, we advanced our innovative pipeline of clinical product candidates. Notably, we dosed the first patient in our Phase 2 LINNET study of lorigerlimab, which will evaluate patients with platinum-resistant ovarian cancer and clear cell gynecologic cancers. We believe lorigerlimab, a differentiated bispecific checkpoint inhibitor, may be uniquely positioned to address the significant unmet need in both indications,” said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “We are focused on continued clinical execution this year and look forward to sharing our progress, including a clinical update from the LORIKEET Phase 2 study in the second half of 2025.”

Updates on Proprietary Investigational Programs

Lorigerlimab is a bispecific, tetravalent PD-1 × CTLA-4 DART® molecule designed to enhance CTLA-4 blockade on dual-expressing, tumor-infiltrating lymphocytes compared to a PD-1/CTLA-4 monoclonal antibody (mAb) combination therapy, while maintaining maximal PD-1 blockade on all PD-1-expressing cells.

  • The LORIKEET Phase 2 trial, a 150-patient randomized study of lorigerlimab in combination with docetaxel vs. docetaxel alone in second-line, chemotherapy-naïve patients with metastatic castration-resistant prostate cancer (mCRPC), is ongoing. The study was fully enrolled in late 2024 and the Company expects to provide a clinical update in the second half of 2025.

  • The first patient has been dosed in the LINNET Phase 2 study evaluating lorigerlimab as monotherapy in patients with either platinum-resistant ovarian cancer (PROC) or clear cell gynecologic cancer (CCGC). Both indications represent areas of unmet need and historically have been relatively insensitive to traditional anti-PD-1 antibody therapy. The LINNET study’s primary endpoint is objective response rate (ORR), with multiple secondary endpoints, including progression free survival (PFS) and duration of response (DoR). The Company anticipates enrolling up to 40 patients with PROC and up to 20 patients with CCGC in LINNET.
