Italian Platelet Technology Assessment Study — IPTAS  

Lymphoma Clinical Trial

Official title: A Multi-center, Single-blind, Randomized, Parallel, Non Inferiority Study to Separately Investigate the Effect of Standard Platelets Versus Platelets Prepared With Two Commercial Procedures of Pathogen Reduction Technologies (PRT) on Bleeding Incidence and Severity in Thrombocytopenic Recipients

Status Terminated

Clinical Trial Summary

Italian Platelet Technology Assessment Study (IPTAS) aims at comparing bleeding frequency and severity after transfusion of standard platelets versus platelets prepared with two commercial pathogen reduction technologies (PRT) and to perform a proteomic analysis of standard versus PRT platelets. The two technologies will be analyzed separately.

Primary endpoint: incidence of bleeding of grade 2 or greater in recipients of PRT platelets versus incidence in recipients of control (standard) platelets.

Secondary endpoints: time to the first grade 2 or greater bleeding event after the first study transfusion; proportion of transfusions given to treat breakthrough bleeding; number of days with grade 2 or greater bleeding during the period of platelet transfusion support; number of platelet units transfused and total dose of platelets transfused per day of thrombocytopenic platelet support; proportion of patients with acute transfusion reactions; post-transfusion platelet count increments

Observational endpoints: frequency of human leukocyte antigen (HLA) alloimmunization, frequency of clinical refractoriness to platelet transfusion with demonstrated HLA alloimmunization, frequency of clinical refractoriness to platelet transfusion that is persistent during the period of platelet support in the absence of HLA or human platelet antigen (HPA) alloimmunization

Patients will be evaluated for 4 weeks after randomization.

Clinical Trial Description

When patient's platelet count, done in early morning every day, falls below 10000/microliter, physician in charge issues a platelet transfusion request to transfusion service. Transfusion service (which knows patient treatment arm) issues a PRT product or a standard product as indicated, typically within hours of request receipt; patient's physician identifies unit code and intended recipient's code and determines vital signs (pulse, blood pressure, body temp). Transfusion is started and completed in 30 min. Adverse reactions are monitored by ward personnel and once a day IPTAS local coordinator visits the ward, checks IPTAS patients' records, fills IPTAS forms, examines and interviews each enrolled patient and transfers filled forms to data coordinating center in Milan. ;
