NCT04286438

Brief Summary

This is a multi-center, open-label, prospective single-arm study of reversal of the antiplatelet effects of ticagrelor with bentracimab (PB2452) in patients who present with uncontrolled major or life-threatening bleeding or who require urgent surgery or invasive procedure. At least 200 patients will be enrolled from approximately 200 centers in North America, Europe, and Asia-Pacific regions, including mainland China. Patients with reported use of ticagrelor within the prior 3 days who require urgent ticagrelor reversal will be eligible for enrollment. These populations will be enrolled based on separate inclusion criteria.

Outcome Measures

Primary Outcomes (3)

  • Reversal - Platelet Reactivity Units (PRU)

    Minimum % inhibition of PRU within 4 hours of the initiation of study drug as assessed by VerifyNow™ PRUTest™ platelet function assay

    4 hours post-initiation of infusion

  • Hemostasis - Uncontrolled major of life-threatening bleeding - Achievement

    Achievement of effective (graded as good or excellent) hemostasis after initiation of PB2452 infusion will be assessed using prespecified criteria for effective hemostasis for visible and non-visible major bleeding \[Scale (from best to worst) measured as: Excellent, Good, Poor/None\]

    4 hours post-initiation of infusion

  • Hemostasis - Urgent surgery or invasive procedure - Achievement

    Achievement of effective hemostasis following initiation of PB2452 infusion will be centrally adjudicated using prespecified criteria for effective hemostasis derived from the Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) clinical bleeding scale \[GUSTO scale (from best to worst): Effective (no bleeding, mild bleeding or moderate bleeding) or Not effective (severe bleeding)\]

    4 hours post-initiation of infusion

Secondary Outcomes (12)

  • Minimum % inhibition of Platelet Reactivity Index (PRI) (VASP)

    4 hours post-initiation of infusion

  • Maximum reversal of PRU assessed by VerifyNow™ PRUTest™

    4 hours post-initiation of infusion

  • Maximum reversal of PRI assessed by VASP

    4 hours post-initiation of infusion

  • Proportion of subjects achieving reversal of platelet inhibition of ticagrelor using PRU and PRI - 60%

    Any time point between infusion initiation and Day 3 (Pre-dose, 5-10 minutes, 30+5 minutes, 1+0.25 hours, 4+0.25 hours, 12+0.5 hours, 24+1 hours, and Day 3)

  • Proportion of subjects achieving reversal of platelet inhibition of ticagrelor using PRU and PRI - 80%

    Any time point between infusion initiation and Day 3 (Pre-dose, 5-10 minutes, 30+5 minutes, 1+0.25 hours, 4+0.25 hours, 12+0.5 hours, 24+1 hours, and Day 3)

  • +7 more secondary outcomes

Study Arms (1)

Bentracimab (PB2452) Infusion - Open Label Active Drug

EXPERIMENTAL

Bentracimab (PB2452) 18 g Intravenous Infusion over a 16 hour duration. For patients with uncontrolled major or life-threatening bleeding or in need of urgent surgery or invasive procedure.

Drug: Bentracimab (PB2452) Infusion

Interventions

Bentracimab (PB2452) 18 g Intravenous Infusion over a 16 hour duration. In subjects with potential drug interaction from recent concomitant use of moderate or strong CYP3A inhibitors with ticagrelor, the active treatment period may be 24 hours and 10 min if receiving the 36g infusion. In patients presenting with intracranial hemorrhage (ICH), brain imaging within 2 hours of initiation of study drug and at least one follow-up brain imaging performed 12-24 hours post completion of PB2452.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female \>18 years of age with documented or verbal informed consent. Emergency consent may be obtained where permitted by local regulations and institutional approval.
  • History or documentation of ticagrelor intake within the prior 3 days
  • Patients described below who require urgent reversal of the antiplatelet effects of ticagrelor:
  • Patients with uncontrolled major or life-threatening bleeding, requiring urgent reversal of the antiplatelet effects of ticagrelor. It is expected that enrolled patients would have characteristics similar to those described below:
  • Potentially life-threatening bleeding with signs or symptoms of hemodynamic compromise, e.g., systolic blood pressure \< 90 mm Hg and signs or symptoms of low cardiac output not otherwise explained
  • Bleeding in a critical organ or closed space, such as intracranial, intraspinal, intraocular, retroperitoneal, intra-articular, pericardial, or intramuscular bleed with compartment syndrome
  • Visible, uncontrolled bleeding associated with a corrected hemoglobin level \< 8.0 g/dL, a fall in hemoglobin level of ≥ 2.0 g/dL (1.24 mmol/L) from a known baseline, or requirement for transfusion of 2 or more units of packed red blood cells (PRBC)
  • Patients requiring urgent surgery or invasive procedure when it is not medically advisable either to proceed urgently with impaired hemostasis or to delay the urgent procedure for 3 or more days due to the high risk of bleeding. These patients may typically be in any of the following clinical situations:
  • Requires urgent surgery or invasive procedure known to be associated with a risk of significant bleeding (such as cardiac surgery, neurosurgery, or major orthopedic surgery)
  • Requires urgent surgery or invasive procedure that may have an adverse procedural outcome if hemostasis is impaired (such as neurological, spinal, ophthalmological, urological, or orthopedic surgery)
  • At risk of experiencing life-threatening events, such as, shock, myocardial infarction, or stroke, if significant intraoperative or postoperative bleeding occurs (such as in elderly patients or patients with underlying cardiac or pulmonary disease who have limited cardiopulmonary reserve)

You may not qualify if:

  • Known sensitivity or contraindication to PB2452 or any of its excipients
  • Patients in whom ticagrelor reversal is not considered urgent, e.g., patients with stable or non-acute conditions who have low hemoglobin due to chronic, low-grade gastrointestinal bleeding or who have stable, remote, or asymptomatic intracranial hemorrhage
  • Patients expected to be clinically unsalvageable, such as, patients with end-stage cancer or patients with overwhelming sepsis
  • Known use of clopidogrel, prasugrel or ticlopidine within 5 days of study drug administration; known use of antiplatelet GPIIb/IIIa inhibitors, or cangrelor within 5 half-lives of expected study drug administration; or known use of warfarin, dabigatran, rivaroxaban, apixaban, or edoxaban within 5 half-lives of expected study drug administration
  • Known recent use (\< 5 day) of vitamin K, prothrombin complex concentrate, recombinant factor VIIa, idarucizumab, or andexanet-alfa (coagulation factor Xa (recombinant), inactivated-zhzo)
