PhaseBio Reports Recent Business Highlights and Third-Quarter 2020 Financial Results

Expanded pivotal Phase 3 REVERSE-IT trial of product candidate bentracimab (PB2452) for reversal of antiplatelet effects of ticagrelor into Canada and dosed first patients outside the United States

Resuming enrollment in ongoing Phase 2b trial of pemziviptadil (PB1046) in pulmonary arterial hypertension

MALVERN, Pa. & SAN DIEGO–(BUSINESS WIRE)–$PHAS #TakeItToHeart—PhaseBio Pharmaceuticals, Inc. (Nasdaq: PHAS), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapies for cardiovascular and cardiopulmonary diseases, today provided an update on corporate activities and reported third-quarter 2020 financial results.

“In the third quarter, PhaseBio continued to make progress and build momentum on our mission to develop novel treatments for serious cardiovascular diseases, primarily through the growth of our global clinical trial footprint for our lead product candidate bentracimab,” said Jonathan P. Mow, Chief Executive Officer of PhaseBio Pharmaceuticals. “In October, we expanded enrollment of our pivotal Phase 3 REVERSE-IT Trial for bentracimab into Canada where we dosed the first patients outside the United States. With continued widespread use of antiplatelet therapies for patients with acute coronary syndrome, both in the United States and globally, there continues to be a significant unmet need for a novel therapy like bentracimab that has the potential to immediately and sustainably reverse the antiplatelet effects of ticagrelor in patients requiring urgent surgeries or experiencing major bleeding events.”

Mow continued, “We’re also pleased to be resuming enrollment for VIP, our Phase 2b trial of pemziviptadil for patients with pulmonary arterial hypertension (PAH). Looking ahead, we remain focused on delivering on our key clinical development milestones for bentracimab and pemziviptadil in 2021 and will be working in the near term on the preparation of our regulatory filings and commercialization efforts for bentracimab.”

Recent Pipeline and Business Highlights

• Expanded Pivotal Phase 3 REVERSE-IT Trial for Lead Product Candidate Bentracimab into Canada and Dosed First Patients: In October 2020, PhaseBio announced that it had expanded its Phase 3 REVERSE-IT trial for its lead product candidate bentracimab (PB2452) into Canada, where the first patients outside of the United States have now been enrolled and dosed. Bentracimab is a novel, human monoclonal antibody fragment that in earlier trials has shown immediate and sustained reversal of the antiplatelet effects of Brilinta® (ticagrelor). Cardiovascular disease remains a leading cause of mortality in the United States, Canada and globally. The lack of reversal agents for patients taking antiplatelet therapies who require urgent surgery or experience a major bleeding event remains a critical unmet need. The ongoing global Phase 3 trial of bentracimab has been named REVERSE-IT (Rapid and SustainEd ReVERSal of TicagrElor – Intervention Trial). (Read more…)

• Resuming Enrollment in Ongoing Phase 2b Trial of Pemziviptadil (PB1046) in PAH: In October 2020, PhaseBio announced that the ongoing Phase 2b trial of pemziviptadil in patients with PAH, named the VIP trial (Vasoactive Intestinal Peptide in adult patients with pulmonary arterial hypertension), is resuming enrollment after a pause related to the impacts of the COVID-19 pandemic and re-prioritization of drug supply to the VANGARD trial. To date, approximately one-third of the patients targeted for enrollment have completed the initial 16 week protocol, with approximately 90% of these patients electing to enroll in VIP EXTEND (Vasoactive Intestinal Peptide extension trial in adult patients with pulmonary arterial hypertension), the open label extension of the Phase 2b trial. Results from the VIP trial are expected to be reported in the second half of 2021.

• Discontinued VANGARD Clinical Trial to Evaluate Pemziviptadil in Hospitalized COVID-19 Patients: In October 2020, PhaseBio announced that after a strategic review of the VANGARD Phase 2 clinical trial, which included an assessment of the rapidly evolving COVID-19 treatment landscape, feedback from the U.S. Food and Drug Administration (FDA) and an interim analysis of the VANGARD trial data, the company elected to discontinue the VANGARD trial and refocus resources on its core pipeline programs. Importantly, pemziviptadil was generally well tolerated, and there was no adverse safety signal reported in the VANGARD trial. In addition, an independent data safety monitoring board did not identify any safety concerns related to pemziviptadil.

• SFJ Financing and Co-Development Agreement Update: From execution of the Co-Development Agreement through September 30, 2020, SFJ Pharmaceuticals has funded or reimbursed $31.7 million of clinical trial costs and other expenses of the initial $90 million commitment under the agreement towards the development of bentracimab, leaving $58.3 million of funding remaining available to support the bentracimab Phase 3 program through the end of 2021. PhaseBio is eligible to receive up to an additional $30 million of funding if specific, pre-defined clinical development milestones for bentracimab are met.

Third-Quarter 2020 Financial Results

• Cash and cash equivalents at September 30, 2020 were $39.4 million, compared to $74.0 million at December 31, 2019. The decrease reflects cash used in operating activities.

• Net loss for the quarter was $25.1 million, compared to a net loss of $11.4 million for the prior-year period.

• Research and development expense increased to $17.4 million, as compared to $9.0 million for the same period in 2019, driven by an increase in manufacturing, clinical and nonclinical development activities related to bentracimab and pemziviptadil.

• General and administrative expense increased to $3.1 million, compared to $2.8 million for prior-year period, primarily due to increases in professional services, personnel, and insurance-related expenses.
