Trial Outcomes & Findings for Study to Evaluate the Safety, Tolerability, PK and PD of PB2452 in Healthy Younger, Older and Elderly Subjects (NCT NCT03928353)
NCT ID: NCT03928353
Last Updated: 2024-05-01
Results Overview
An adverse event (AE) is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it is considered drug-related. A TEAE is defined as any AE not present before exposure to study drug or any AE already present that worsens in intensity or frequency after exposure to study drug. An SAE/suspected unexpected serious adverse reaction if, in the view of either the investigator or Sponsor, it results in any of the following outcomes: death, life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, or congenital anomaly or birth defect. A summary of serious and all other non-serious adverse events, regardless of causality, is located in the Reported Adverse Events module.

Participant Flow
Healthy, younger, older, and elderly male and female participants were enrolled and randomized in a single center.
Participant milestones
| Measure |
Part A - Cohort 1
Older and elderly participants pretreated with ticagrelor + ASA received 18 g of PB2452 intravenously (IV) during the treatment period.
|
Part A - Cohort 2
Older and elderly participants pretreated with ticagrelor + ASA received 18 g of PB2452 IV during the treatment period. Following completion of Cohort 1, the previous Sponsor instructed the clinical site to administer study drug in the same manner as in Cohort 1 in Cohort 2.
|
Part A - Placebo (Pooled)
Older and elderly participants pretreated with ticagrelor + ASA received 0.9% sodium chloride IV during the treatment period.
|
Part B - Cohort 3
Healthy and younger participants pretreated with a high dose of ticagrelor (180 mg BID) received 36 g of PB252 IV during the treatment period.
|
Part B - Placebo
Healthy and younger participants pretreated with a high dose of ticagrelor (180 mg BID) received 0.9% sodium chloride IV during the treatment period.
