Trial Outcomes & Findings for A Study to Assess Recovery and Survival of Radiolabeled Apheresis Platelet Components Treated With the INTERCEPT Blood System for Platelets With LED Illuminator. (NCT NCT06697223)

NCT ID: NCT06697223

Last Updated: 2026-08-04

Results Overview

Recovery of Test platelets stored for 5 Days as compared to fresh controls. In vivo recovery was expressed as proportion of infused in days and was estimated using a multiple-hit model. The FDA acceptance criteria for survival is \>66% of control with the lower bound of a two-sided 95% CI for the mean treatment difference (Test-0.66\*Control) in survival is greater than or equal to zero.

Participant Flow

A subject was considered "enrolled" upon signing the informed consent form.

Subjects who initiated an apheresis collection were included in the ITT/Safety Analysis Set. Subjects who had data for recovery and survival data and/or other in vitro characteristics were in the the Modified Intention to Treat (mITT). Randomized and infused subjects who had both paired (Test and Control) recovery and paired survival data, Test recovery and/or survival less than Control recovery and/or survival and complied with the protocol were in the Per Protocol Set (PPS).

Simultaneous Administration of Test and Control Platelets
INTERCEPT treated platelets (Test) from 24 healthy subjects, stored for 5 days, were prepared for radiolabeling following the Variant 1 methodology. The radiolabeled autologous Test and Control platelets, approximately 5 to 30 mL, were simultaneously administered intravenously into the subject.

PRIMARY outcome

Timeframe: 11 days (+/- 1 day) post infusion of radiolabeled Test platelets stored for 5 days and fresh Control platelets

Population: The Per Protocol Set (PPS) included all randomized and infused subjects who have both paired (Test and Control) recovery and paired survival data, Test recovery and survival less than Control recovery and survival and otherwise complied with the protocol without any protocol deviation potentially affecting the primary efficacy outcome. PPS was the primary analysis population for the efficacy evaluation.

Recovery of Test platelets stored for 5 Days as compared to fresh controls. In vivo recovery was expressed as proportion of infused in days and was estimated using a multiple-hit model. The FDA acceptance criteria for survival is \>66% of control with the lower bound of a two-sided 95% CI for the mean treatment difference (Test-0.66\*Control) in survival is greater than or equal to zero.

An AE is any untoward medical occurrence in a subject or clinical investigation subject administered an investigational product and which does not necessarily have a causal relationship with this treatment. Therefore, an AE can be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of an investigational product whether or not related to the investigational product.
