PB2452 – Reversal Agent for Ticagrelor
PB2452 - Novel reversal agent for Brilinta (ticagrelor) • Within the P2Y12 antagonist class of oral antiplatelet therapies, ticagrelor has proven superiority vs. clopidogrel, and a unique reversible binding profile − Clopidogrel and prasugrel, the other members of the oral P2Y12 antagonist class, both permanently bind to the receptor and cannot be reversed • PB2452 is the only specific reversal agent in development for ticagrelor − PB2452 clinical data to date have demonstrated both immediate (<5 min) and sustained reversal (~24 hours) of ticagrelor antiplatelet effects • Approval would differentiate ticagrelor on safety vs. other oral antiplatelet agents − Expect further differentiation of ticagrelor vs. other P2Y12 agents to drive increased demand Significant unmet need for antiplatelet agent reversal Major Bleeding Urgent Surgery or Intervention • Intracranial Haemorrhage (ICH), GI, Trauma • Currently oral P2Y12 agents, including ticagrelor, require a 5 day washout prior to surgery1,2 • All oral antiplatelet agents have the potential to cause major bleeding, which can be severe or even fatal . Urgent surgery often cannot wait 5 days . Higher thrombotic risk during washout • PB2452 immediately and sustainably reverses the antiplatelet effects of ticagrelor • In Phase 1 and Phase 2a studies, PB2452 immediately and sustainably reversed ticagrelor inhibition of platelet activation . Enables immediate surgery 1.

PB2452: Well-Characterized Mechanism of Reversal of Ticagrelor Ticagrelor PB2452 ADP This is a reversible ADP ADP process with P2Y12 ticagrelor cycling Platelet Receptor on/off the P2Y12 receptors ADP binds to P2Y12 receptor Ticagrelor binds to P2Y12, inhibiting PB2452 binds to free ticagrelor 1. causing platelet aggregation 2. ADP-induced platelet aggregation 3. with very high affinity ADP ADP ADP Platelet 4. PB2452:ticagrelor binding is 5. As free ticagrelor is eliminated, 6. PB2452:ticagrelor is eliminated preferential to ticagrelor:P2Y12 ADP can again activate the P2Y12 from the bloodstream binding receptor, restoring platelet activity 7 Copyright © 2019 PhaseBio Pharmaceuticals, Inc.

Positive Preliminary PB2452 Phase 2a Results • Positive preliminary results from the PB2452 Phase 2a trial were disclosed via press release1 − First trial of PB2452 to include older and elderly subjects (ages 50-80) on dual antiplatelet therapy (DAPT) of ticagrelor and low-dose aspirin − Subjects in the trial resembled the patient population most likely to be treated with ticagrelor and potentially benefit from PB2452, if approved • Per FDA request, the Phase 2a trial also explored reversal of supratherapeutic blood levels of ticagrelor that could result from ticagrelor overdosage or drug-drug interactions − PhaseBio believes an appropriate PB2452 regimen has been identified for these patients • Confirmed dosing regimen to be used in the Phase 2b and Phase 3 trials • Results to be presented at an upcoming medical congress Older & Elderly Subjects Supratherapeutic Dose PB2452 Phase 2a Trial on DAPT of Ticagrelor Immediate and sustained reversal of the antiplatelet effects of ticagrelor ✔ ✔ Efficacy demonstrated using same three assays used in Phase 1 trial2 ✔ ✔ Results highly correlated across assays ✔ ✔ Generally well tolerated with only minor adverse events reported ✔ ✔ 1. https://investors.phasebio.com/news-releases/news-release-details/phasebio-announces-completion-phase-2a-clinical-trial-pb2452 11 2.

PB2452 Regulatory Updates Development plan for PB2452 designed with objective to broadly support global regulatory filings Separate written guidance from FDA and EMA indicates that a single, non-randomized, open-label Phase 3 trial of PB2452 in both surgical and major bleeding populations has the potential to support regulatory filings in the United States and the European Union EMA: • Received written Scientific Advice: February 2020 − Written guidance from the CHMP of the EMA generally agrees with PhaseBio’s proposed development plan for PB2452 • Granted PRIME designation: February 2020 − PRIME designation granted by the EMA to support medicines that demonstrate the potential to address substantial unmet medical need1 − Potentially expedites the review and approval process FDA: • Received meeting minutes from PB2452 End-of-Phase 1 meeting: August 2019 − FDA alignment on development plan and Accelerated Approval regulatory path • PB2452 granted Breakthrough Therapy designation: April 2019 − Breakthrough Therapy designation is designed to expedite the development and review of promising new drugs2 1.

PB6440 – Aldosterone Synthase Inhibitor for Resistant Hypertension
PB6440 for Resistant Hypertension • Upwards of 10 million patients in the United States have resistant hypertension and are at risk for serious, costly medical consequences (stroke, heart attack, kidney failure, etc.)1 • Physicians currently prescribe numerous combinations of antihypertensives to lower blood pressure and diminish risk • Blocking aldosterone has been shown to be an effective mechanism for treating resistant hypertension − Currently available aldosterone blockers suffer from poor potency and pharmacokinetics (eplerenone) or poor tolerability (spironolactone) and thus are rarely used • Recent draft guidance from the FDA outlines a streamlined regulatory path for novel drugs to treat resistant hypertension without the need for large outcomes studies2 • Market research indicates that payors aware of high medical costs associated with resistant hypertension Large, growing patient population coupled with a high unmet need creates an attractive opportunity for a novel therapy to help patients and care providers better manage blood pressure 1.
