New: 50% response rate at RP2D in pancreatic cancer, presented at ESMO GI 2025
Pipeline · Lixumistat (IM156)

One asset. Multiple indications.

Lixumistat is ImmunoMet's lead compound, a selective OxPhos inhibitor with a safety profile appropriate for further development. Lixumistat's anti-cancer potential was originally investigated in patients with advanced solid tumors (NCT03272256) and more recently in advanced cancer patients (NCT05497778). Additionally, the safety, pharmacokinetics, pharmacodynamics, and potential effect of food on pharmacokinetics were characterized in healthy subjects.

Lead Asset

LixumistatBest-in-class Protein Complex 1 inhibitor

An orally administered small-molecule biguanide with robust in vitro activity and in vivo efficacy across selected cancers. It is the first PC1 inhibitor to demonstrate target engagement in humans at tolerable doses and define a recommended Phase 2 dose. Importantly, lixumistat demonstrated robust clinical activity in patients with advanced pancreatic cancer.

Safety SupportsNo dose-limiting toxicities in advanced solid tumours
Clinical ActivityEncouraging PDAC data supports phase 2 study
Once-daily oralTarget inhibition confirmed in healthy subjects
Pan-cancer potentialAny OxPhos-dependent tumour
Lixumistat (IM156) chemical structure: a biguanide bearing a pyrrolidine ring and a 4-(trifluoromethoxy)phenyl group
Pipeline

A de-risked lead asset with opportunity to expand.

Lixumistat's mechanism applies anywhere disease becomes OxPhos-dependent. See the investment case or talk to our team.
