“This significant financing from a committed, knowledgeable, and sophisticated investor syndicate positions us well to continue development.”

Last month, Gossamer Bio signed an exclusive global licence agreement to develop and commercialise Aerpio Pharmaceuticals’ drug candidate called AKB-4924 along with additional related compounds.

AKB-4924 is an investigational stabiliser of hypoxia-inducible factor-1 alpha (HIF-1 alpha) and is being developed for the treatment of inflammatory bowel disease (IBD).

The candidate has now been named a ‘GB004’. In animal IBD models, the therapeutic is said to have demonstrated anti-inflammatory and mucosal wound healing effects.

Aerpio already conducted preclinical study and a Phase I single ascending dose trial, which indicated favourable safety and efficacy profile.

A Phase I multiple ascending dose study was launched in May this year to evaluate the pharmacokinetics, further safety and tolerability of GB004 in 24 healthy volunteers.
