Item 1.01 Entry into a Material Definitive Agreement
On March 10, 2021, PhaseBio Pharmaceuticals, Inc. (the “Company”) entered into a Supply Agreement (the “Agreement”) with BioVectra Inc. (“BioVectra”) for the manufacture and supply by BioVectra of bulk drug substance (API) for the Company’s lead product candidate bentracimab, also known as PB2452 (“Product”), for commercial distribution following regulatory approval. Under the terms of the Agreement, BioVectra has committed to maintaining capacity to manufacture an agreed number of batches of Product each year, and the Company has committed to purchase a specified minimum number of batches of Product per year (“Minimum Annual Commitment”), although the Company is free to contract with third parties for the manufacture of Product.
The Company will pay a supply price per batch of Product (the “Supply Price”) to be determined after the manufacturing process for Product is validated in accordance with the Agreement (“Validation”), plus the cost of certain consumables, raw materials, and third-party testing. The parties have agreed that the initial Supply Price of Product will be within a specified percentage of the estimated supply price set forth in the Agreement and will remain firm through the second anniversary of Validation. Thereafter, on an annual basis following the second anniversary of Validation, either party may propose adjustments to the Supply Price for increases or decreases based on a specified inflation rate, subject to a maximum inflation adjustment per year, and BioVectra may propose adjusting the supply price beyond that inflation rate if it can document extraordinary increases or decreases in costs, subject to a specified maximum percentage increase or decrease per year.
Pursuant to the Minimum Annual Commitments, the Company is obligated to purchase a minimum of (i) approximately $14 million of batches of Product in years 2022 through 2023, (ii) approximately $37 million of batches of Product in 2024, and (iii) approximately $48 million of batches of Product in each of years 2025 through 2031. In the event the Company does not purchase the applicable Minimum Annual Commitment in a given year, the Company will be obligated to make a payment to BioVectra in an amount equal to the then-applicable Supply Price per batch multiplied by the difference between the Minimum Annual Commitment for such year and the number of batches of Product the Company actually purchased in such year (“Minimum Shortfall Payment”), except in the event that BioVectra was unable to deliver the number of batches ordered by the Company in such year. In the event of certain serious or extended failures by BioVectra to supply Product in the quantities ordered by the Company in a given year, the Company’s Minimum Annual Commitment for such year (and potentially one or more subsequent years) will be subject to reduction, and the Company’s obligation to make a Minimum Shortfall Payment for such year (and potentially one or more subsequent years) will be waived. The Company will have the right to reduce the Minimum Annual Commitments for the year 2026 and subsequent years by up to a specified maximum percentage per year. Further, if the Company is only able to obtain regulatory approval for products incorporating Product in only one of the U.S. or Europe, BioVectra and the Company have agreed to discuss in good faith an amendment to the Agreement to reflect decreased requirements for Product and impacts to the Supply Price to reflect lower volume commitments.
The initial term of the Agreement commences on the effective date of the Agreement and continues until the tenth anniversary of Validation. The term of the Agreement may be extended for additional one-year periods upon mutual agreement of the parties. Either party may terminate the Agreement in the event of an uncured material breach by the other party or upon the occurrence of certain events of insolvency of the other party. The Company may terminate the Agreement (i) in the event of certain regulatory compliance failures by BioVectra or any person employed or retained by it to perform services under the Agreement, or (ii) subject to payment of a termination fee to BioVectra (the amount of which decreases over the term of the Agreement from an initial maximum in the mid-teens of millions of dollars to zero), in the event the Company decides that it will not, or is unable to, pursue regulatory approval or commercialization of products incorporating Product or in the event of termination of the Company’s license to the Product from MedImmune Limited. The Company may also terminate the Agreement without cause and without payment of a termination fee upon 24 months’ notice following the fifth anniversary of regulatory approval of a product incorporating Product by either the U.S. Food and Drug Administration or European Medicines Agency.
The Agreement contains, among other provisions, representation and warranties, indemnification obligations, confidentiality, publicity, audit and inspection, and intellectual property sharing provisions in favor of each party that are customary for an agreement of this nature.
The foregoing summary of the Agreement is not complete and is qualified in its entirety by reference to the text of the Agreement, a copy of which will be filed as an exhibit to the Registrant’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2021.

Exhibit 99.1

PhaseBio Pharmaceuticals and BioVectra Enter into Supply Agreement to Support Development and Commercialization of Bentracimab

Malvern, PA and San Diego, CA - March 11, 2021 - PhaseBio Pharmaceuticals, Inc. (Nasdaq: PHAS), a clinical-stage biopharmaceutical company focused on the development and commercialization of novel therapies for cardiopulmonary diseases, and BioVectra Inc., an innovative global contract development and manufacturing organization (CDMO), today announced a commercial scale supply agreement for the production of bentracimab, PhaseBio’s lead product candidate currently in a global Phase 3 clinical trial. Bentracimab is a novel, human monoclonal antibody fragment that in earlier clinical trials has shown immediate and sustained reversal of the antiplatelet effects of Brilinta® (ticagrelor).

Under the terms of the agreement, BioVectra will provide its integrated CDMO services for the manufacturing of the active pharmaceutical ingredient (API) of bentracimab for use in PhaseBio’s ongoing global clinical trials and for global commercial use upon regulatory approval. Utilizing a cost-efficient, E.coli-based manufacturing process at its manufacturing site in Windsor, Nova Scotia, BioVectra recently completed the first GMP run of bentracimab at commercial scale. Going forward, PhaseBio plans to integrate API manufactured at commercial scale at BioVectra into the ongoing Phase 2b and Phase 3 REVERSE-IT clinical trials to support global regulatory filings.

“As we prepare for the next phase of growth for bentracimab, we’re pleased to sign this agreement with BioVectra for the commercial supply and development of our novel reversal agent,” said Jonathan P. Mow, Chief Executive Officer of PhaseBio Pharmaceuticals. “Having recently expanded our global Phase 3 REVERSE-IT trial into Canada and the European Union, and with other countries on the horizon, the signing of this agreement and the completion of our first commercial-scale manufacturing run are important steps as we continue preparing our regulatory filings and commercialization efforts for bentracimab. We believe BioVectra will be an excellent partner as we move down the path of developing and potentially commercializing the first specific antiplatelet reversal agent for ticagrelor.”

Pending approval of the drug by regulators, the partnership will enable PhaseBio to supply bentracimab at launch in the U.S. to key trauma and critical care centers. Based on data from IQVIA®, PhaseBio believes that providing adequate bentracimab supply for initial stocking and demand-based reorders for these key centers will make bentracimab accessible to approximately 80% of the population in the U.S. who are prescribed P2Y12 inhibitors like ticagrelor.

“We’re excited to be partnering with PhaseBio under this new commercial agreement for the high-volume scale-up and global supply of bentracimab,” said Oliver Technow, Chief Executive Officer of BioVectra. “BioVectra is an expert CDMO with proven, specialized capability in scaling the most complex biologic drug substances produced from fermentation. Leveraging our fully integrated approach and 50 years of experience, our highly-skilled team looks forward to continuing to make a difference in patients’ lives by delivering on and supporting PhaseBio’s global commercialization of bentracimab from our new, large-scale Microbial Biomanufacturing facility.”

About Bentracimab (PB2452)

Bentracimab is a novel, recombinant, human monoclonal antibody antigen-binding fragment designed to reverse the antiplatelet activity of ticagrelor in major bleeding and urgent surgery situations. In a Phase 1 clinical trial, bentracimab demonstrated the potential to bring life-saving therapeutic benefit through immediate and sustained reversal of ticagrelor’s antiplatelet activity, mitigating concerns regarding bleeding risks associated with the use of antiplatelet drugs. The Phase 1 clinical trial of bentracimab in healthy volunteers was published in the New England Journal of Medicine in March 2019. In April 2019, bentracimab received Breakthrough Therapy Designation from the FDA. Breakthrough Therapy Designation may be granted by the FDA when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapy. In September 2019, PhaseBio completed a Phase 2a trial in which bentracimab was investigated in older and elderly subjects on dual antiplatelet therapy of ticagrelor and low-dose aspirin. Additionally, the Phase 2a trial investigated a bentracimab regimen for the reversal of supratherapeutic doses of ticagrelor in healthy younger subjects. In both arms of the trial, bentracimab achieved immediate and sustained reversal of the antiplatelet effects of ticagrelor and was generally well-tolerated, with only minor adverse events reported. These results are consistent with the results observed in healthy younger subjects treated with ticagrelor in the previously published Phase 1 trial. PhaseBio initiated the REVERSE-IT trial, a pivotal Phase 3 clinical trial of bentracimab, in March 2020 to support a Biologics License Application for bentracimab in both major bleeding and urgent surgery indications. There are currently no approved reversal agents for ticagrelor or any other antiplatelet drugs.
