Frontier’s pipeline is focused on delivering precision medicines to patients with cancer.
Frontier’s therapeutic priorities are validated targets with genetically-defined patient populations that have not been successfully drugged using standard screening and chemistry strategies to date. Frontier is challenging the status quo of therapeutic possibilities by applying next generation drug discovery strategies supported by cutting edge technologies. The approach to building our pipeline is to let the science lead the way. This philosophy spans our drug development process – including the identification of targets and the use of genetics to identify patient subtypes most likely to benefit from our therapies, as well as the implementation of biomarker strategies to accelerate development.
Historically, the development of new medicines has relied heavily on a set of defined structural features in the target protein (e.g., substrate and ligand binding pockets) that are not available or easily identifiable in the majority of the human proteome. Thus, traditional drug discovery has failed to deliver therapeutics against the majority of pathological proteins.
Covalent drugs bind to the target of interest, then form a chemical bond with the target. This strategy provides an advantage when targeting proteins with poorly defined pockets or disordered domains, providing an anchor point to build potent and selective drug molecules. Covalent drugs form a long-lived complex with a target. By binding to a precise site on a target of interest, covalent drugs can inhibit the protein’s disease-related activity. Covalent drugs include aspirin, ibrutinib, omeprazole, sotorasib, and penicillin.
The collaboration with AbbVie expands the use of Frontier’s technologies to immunology, as well as the development of next generation targeted protein degraders with novel E3 ligases as recruiters. The goal with targeted protein degraders is to selectively remove pathological proteins by causing their physical destruction using the cell’s own machinery. This is based on recent breakthroughs in the understanding of the cellular factories controlling protein production and degradation.
