Apollomics Inc. announced the completion of enrollment in its Phase 3 bridging study evaluating uproleselan (APL-106), an investigational, first-in-class E-selectin antagonist, added to a standard chemotherapy regimen for the treatment of adults with relapsed or refractory acute myeloid leukemia (relapsed/refractory AML). This Phase 3 bridging study is being performed in China with Chinese r/r AML patients. A total of 140 adult patients across 20 sites in Greater China with primary refractory AML or relapsed AML (first or second untreated relapse) and eligible to receive induction chemotherapy have been randomized to either uproleselan combined with chemotherapy or placebo plus chemotherapy.

Apollomics licensed uproleselan from GlycoMimetics (Nasdaq: GLYC), including the rights to clinical development, production and commercial sales in the Greater China market (Mainland China, Hong Kong, Macau and Taiwan). The primary endpoint for the Phase 3 bridging study is overall survival. Secondary outcome measures include the rate and duration of remission and whether uproleselan can reduce the rate of oral mucositis, a chemotherapy-related side effect.

About Uproleselan: Uproleselan (APL-106) is an investigational, first-in-class E-selectin antagonist discovered and developed by GlycoMimetics (Nasdaq: GLYC), currently in a broad development program including a late-stage Phase 3 trial in acute myeloid leukemia (AML). Apollomics licensed uproleselan from GlycoMimetics, and Apollomics has the rights to clinical development, production and commercial sales in the Greater China market (Mainland China, Hong Kong, Macau and Taiwan). Uproleselan has received Breakthrough Therapy and Fast Track designations from the U.S. Food and Drug Administration and Breakthrough Therapy designation from the Chinese National Medical Products Administration for the treatment of adult AML patients with relapsed or refractory disease.

E-selectin is expressed on the surface of blood vessels, and its binding to myeloid cells confers a pro-survival effect via NF-kB signaling. Uproleselan is being developed to provide a novel approach to disrupting established mechanisms of leukemic cell resistance.
