PhaseBio Pharmaceuticals is a technology company.
PhaseBio Pharmaceuticals develops novel therapies for serious cardiovascular diseases, leveraging its elastin-like polypeptide (ELP) technology to create candidates with enhanced pharmacokinetics. Its pipeline includes bentracimab for ticagrelor antiplatelet reversal, pemziviptadil for pulmonary arterial hypertension, and PB6440, an aldosterone synthase inhibitor for treatment-resistant hypertension.
Founded in 2002, PhaseBio originated from the work of Ashutosh Chilkoti, a Duke University professor. Chilkoti developed the ELP biopolymer platform, enabling creating long-acting therapeutic proteins and peptides. This innovation addressed treatment limitations by extending drug half-lives, offering improved efficacy and patient convenience.
The company targets patients with critical cardiovascular challenges, including those requiring ticagrelor reversal, individuals with pulmonary arterial hypertension, and patients with uncontrolled hypertension. PhaseBio aims to deliver innovative medicines addressing these unmet needs, striving for superior patient outcomes and improving the quality of life for patients.

PhaseBio Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company developing novel therapies for cardiovascular and cardiopulmonary diseases, leveraging its proprietary elastin-like polypeptide (ELP) biopolymer technology to improve drug pharmacokinetics and dosing.[1][2][4] Its lead product candidate, bentracimab (PB2452), is a reversal agent for the antiplatelet drug ticagrelor, used to treat patients with acute coronary syndrome (ACS) at risk of bleeding during surgery or emergencies; it also advances PB6440, a preclinical oral aldosterone synthase inhibitor for treatment-resistant hypertension.[1][2] PhaseBio serves patients with high unmet needs in cardiovascular care, solving problems like bleeding risks from antiplatelet therapies and resistant hypertension through extended half-life fusion proteins that enable less frequent dosing.[1][2][4] With around 60 employees and over $389 million in total funding, the company has shown revenue growth from $668K in 2018 to $10.83M in 2021, though it remains pre-commercialization.[1][2]
PhaseBio emerged from expertise in protein engineering and cardiovascular therapeutics, with CEO Jonathan Mow leading since 2014, alongside key executives like CTO John Lee (since 2016) and CFO Lawrence Perkins (since 2022).[1] The company built its foundation on the ELP technology platform, initially applied to candidates like PB1046 (a vasoactive intestinal peptide agonist for pulmonary arterial hypertension), evolving to focus on high-impact areas like ticagrelor reversal amid rising cardiovascular disease burdens—claiming over 600,000 U.S. deaths annually.[2][4][5] Early traction came through 11 funding rounds totaling $389M, including a $120M recent raise, supporting clinical advancement of bentracimab and preclinical work on PB6440.[2]
PhaseBio rides the exploding cardiovascular disease market, affecting 1 in 4 people with rising prevalence due to aging populations and comorbidities, outpacing even cancer in U.S. mortality.[4][5] Timing aligns with surging demand for precision therapies amid antiplatelet overuse in ACS (millions prescribed ticagrelor annually), where no dedicated reversal agent exists, amplified by post-PCI bleeding risks.[1][2] Favorable forces include biopharma's shift to fusion protein platforms for better PK profiles and venture funding in cardio ($389M raised), positioning PhaseBio to influence emergency cardiology and hypertension treatment ecosystems through innovative, patient-centric drugs.[2][4]
PhaseBio's path hinges on bentracimab's clinical readout and potential FDA approval as the first ticagrelor reversal agent, unlocking a multi-billion-dollar niche in perioperative ACS care, alongside PB6440's progression to trials for hypertension.[1][2] Trends like AI-driven drug design, gene therapies, and personalized cardio meds will shape its journey, potentially expanding ELP to gene-delivered biologics or combo therapies. Its influence could grow via partnerships or acquisition by big pharma seeking cardio pipeline gaps, evolving from clinical-stage innovator to commercial force—cementing its role in taming cardiovascular epidemics.[1][2][4]
