The board of directors Ascletis Pharma Inc. of the Company announces the completion of enrollment of 120 patients in the Phase III registration clinical trial of ASC40 combined with bevacizumab for treatment of recurrent glioblastoma (rGBM). ASC40 is an oral, selective small molecule inhibitor of fatty acid synthase (FASN), a key enzyme which regulates de novo lipogenesis (DNL). ASC40 inhibits energy supply and disturbs membrane phospholipid composition of tumor cells by blocking de novo lipogenesis.

The Phase III registration clinical trial (ClinicalTrials.gov Identifier: NCT05118776) is a randomized, double-blind, placebo-controlled, multi-center clinical trial in China to evaluate progression-free survival (PFS), overall survival (OS) and safety of patients with rGBM. Approximately 180 patients will be randomized at the ratio of 1:1 to Cohort 1 (oral ASC40 tablet, once daily + Bevacizumab) and Cohort 2 (matching placebo tablet, once daily + Bevacizumab). Based on prespecified interim analysis condition, 120 patients are likely to lead sufficient events for interim analysis of PFS.

The interim analysis will be conducted after 93 PFS events are observed.
