The poster presentation, entitled ‘Phase 1 Dose Escalation and Cohort Expansion Study Evaluating Safety, PK, PD and Clinical Activity of STC-15, a METTL3 Inhibitor, in Patients with Advanced Malignancies’, describes findings from STORM’s ongoing dose escalation and expansion Phase 1 clinical study to evaluate STC-15, an oral and highly selective small molecule inhibitor of METTL3, in advanced cancer patients. These interim results will focus on safety, pharmacokinetics, target modulation and tumor assessments to support future clinical studies. STC-15 is the first molecule specifically targeting an RNA methyltransferase enzyme to enter clinical development.

Preclinical data has demonstrated that METTL3 inhibition stimulates immune cells and activates interferon pathways, leading to the destruction of tumor cells. The poster presentation will detail the study design, patient demographics, safety data, pharmacokinetics, METTL3 target engagement, mechanistic biomarker data, and assessments of clinical activity.

Details of the poster presentation are as follow:
