GlycoMimetics, Inc. (Nasdaq: GLYC), a biotechnology company specializing in advanced therapies for cancer and inflammatory conditions, has released the top-line results from its Phase 3 global pivotal trial of uproleselan involving 388 patients with relapsed/refractory (R/R) acute myeloid leukemia (AML). The trial assessed the combination of uproleselan with chemotherapy and found no statistically significant improvement in overall survival compared to chemotherapy alone. Patients treated with uproleselan demonstrated a median overall survival of 13 months, while those in the placebo arm had a median survival of 12.3 months. Adverse events observed were consistent with the expected side effects of the chemotherapy regimen utilized in the study.
Harout Semerjian, Chief Executive Officer of GlycoMimetics, expressed gratitude to the investigators, patients, and families involved in the extensive randomized study. Despite the Phase 3 trial’s outcome falling short of expectations, the company remains committed to thoroughly analyzing the data in collaboration with medical, statistical, and regulatory experts, with plans to present a comprehensive analysis at an upcoming medical conference.
The Phase 3 trial was a randomized, double-blind, placebo-controlled study evaluating uproleselan in combination with either MEC (mitoxantrone, etoposide, and cytarabine) or FAI (fludarabine, cytarabine, and idarubicin) in patients with R/R AML. Patients received uproleselan or placebo for 8 days over 1 induction cycle and, if applicable, up to 3 consolidation cycles. The primary endpoint was overall survival without transplant censoring, with secondary endpoints including severe oral mucositis incidence, complete remission rate, and remission rate. A total of 388 patients across 70 sites in nine countries participated, randomized equally between treatment and placebo arms.
Additionally, an adaptive Phase 2/3 trial of uproleselan in adults aged 60 years or older with newly diagnosed AML, fit for intensive chemotherapy, is being conducted by the NCI and the Alliance for Clinical Trials in Oncology. This study is evaluating the addition of uproleselan to a standard cytarabine/daunorubicin regimen (7+3) versus chemotherapy alone. The Phase 2 segment completed enrollment of 267 patients in December 2021, with results of the pre-planned Phase 2 event free survival interim analysis pending.
