Safety And Field Evaluation of Plasma Lyophilized for Acute and Surgical Management Applications (SAFE-PLASMA)
A Phase 4, Cluster-Randomized Crossover, Prospective, Multi-Center Trial Evaluating the Safety of Freeze-Dried Plasma and Conventional Plasma Products in Adult Patients
The purpose of this study is to compare the safety of freeze-dried plasma (FDP), known as EZPLAZ, with conventional plasma in adults who need a plasma transfusion. Plasma is the liquid part of blood that contains proteins that help blood clot. The main question is whether the risk of blood clots or death within 7 days after the first transfusion is not unacceptably higher with FDP than with conventional plasma.
Participating hospitals will follow a randomly assigned schedule that determines which plasma product enrolled participants receive during each week. Participants will receive the product assigned to their hospital for that week during the first 24 hours of treatment. The treating physician will determine how much plasma is needed. After the first 24 hours, participants may receive either product if additional plasma is required.
Participants will be followed for 28 days after their first study transfusion. Information about blood clots, transfusion reactions, or other medical problems, and survival. Trial information will come from routine medical care and medical records. Follow-up after hospital discharge may include telephone contact with the participant or their legally authorized representative. No additional laboratory tests are required solely for this study.

実験的：Freeze-Dried Plasma (FDP)
Participants enrolled during a center's assigned freeze-dried period receive EZPLAZ during the index transfusion episode, defined as the first 24 hours beginning with the first assigned plasma infusion. The treating physician determines the number of units required according to clinical need. After this period, either freeze-dried or conventional plasma may be administered if additional plasma is needed. |
Single-donor human plasma supplied in freeze-dried form and reconstituted with sterile water before transfusion. Administered by intravenous or intraosseous infusion as prescribed by the treating physician and in accordance with institutional transfusion policies. Dose is determined by clinical need.

アクティブコンパレータ：Conventional Plasma
Participants enrolled during a center's assigned conventional plasma period receive conventional plasma during the index transfusion episode, defined as the first 24 hours beginning with the first assigned plasma infusion. The treating physician determines the number of units required according to clinical need. After this period, either freeze-dried or conventional plasma may be administered if additional plasma is needed. |
Conventional plasma products selected, prepared, and administered according to each institution's standard of care. The protocol does not restrict the types of conventional plasma used. The treating physician determines the dose based on clinical need.
