Protagonist Therapeutics is a biotechnology company pursuing the discovery and development of target oral peptides as well differentiated alternatives to antibodies, and also as new chemical entities (NCEs) against those targets and life threatening diseases for which suitable small molecule and/or biologic options are not available. Peptides typically suffer from limitations of poor proteolytic stability and therefore find scarce therapeutic utility that is largely limited to ‘injectable drugs’. Protagonist’s technology platform is aimed at overcoming these restrictions and expanding the scope of peptide therapeutics to address unmet needs. Specific emphasis is placed on identifying ‘orally stable’ scaffolds and/or engineering oral stability characteristics onto them. The platform has been optimized over the years and involves synergistic integration of rational drug design, diversity oriented computational tools, phage display libraries, recombinant peptide expression, ex vivo oral stability methods, and peptide/medicinal chemistry techniques. This activity has led to the identification of ‘privileged scaffolds’ with favorable oral stability characteristics. Furthermore, the technology platform is well suited both for de novo discovery against a target and optimization around a given chemical starting point.
PhaseBio is a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapies to treat orphan diseases, with an initial focus on cardiopulmonary indications. Our lead product candidate is PB2452, a novel reversal agent for the antiplatelet drug ticagrelor, and our second product candidate is PB1046, a once-weekly fusion protein for the treatment of pulmonary arterial hypertension. PB1046 utilizes our elastin-like polypeptide technology, which also serves as the engine for our preclinical pipeline. Our proprietary technology platform uses recombinant elastin-like polypeptide (ELP) biopolymers to control the half-life, bioavailability and physical characteristics of molecules for ease of administration. The compounds are engineered for a specific rate of absorption to enhance efficacy and reduce side effects, which may lead to less-frequent dosing and better patient compliance. PB1046 is a vasoactive intestinal peptide (VIP) receptor agonist that leverages our ELP technology for once-weekly dosing. PB1046 is being evaluated in clinical studies in pulmonary arterial hypertension (PAH) and in preclinical studies for the treatment of cardiomyopathy associated with dystrophinopathies. PhaseBio recently concluded a Phase 2a trial of PB1046 in patients with heart failure with reduced ejection fraction. We are also evaluating our development candidate PB2452, a reversal agent for the antiplatelet therapy ticagrelor, in clinical trials. PB2452 was exclusively licensed from MedImmune, the global biologics research and development arm of AstraZeneca, for global development and commercialization by PhaseBio. PhaseBio continues to explore opportunities to apply our ELP biopolymer technology to compounds that may benefit from its unique properties. We are privately owned, with headquarters and research laboratories in Malvern, PA.
