E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to demonstrate the non-inferiority of UVC-treated plasma reduced platelet concentrates (UVC-PCs) in comparison to untreated plasma reduced platelet concentrates (Control-PCs) stored for up to 5 days in adult patients with hematologic or oncologic diseases and thrombocytopenia based on the 1 hour CCI of not more than 30% below the control. |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy objective:
- To compare the post- transfusion PLT recovery, measured by platelet count increments
(24 hour CCI, 1 hour and 24 hour CI) between treatment Groups;*
- To compare PLT and RBC transfusions support between treatment Groups;*
Secondary safety objective:
- Rate of bleeding ≥ WHO grade 3 and grade 4;*
- Rate of clinical refractoriness;*
- Rate of immunologic refractoriness;*
- Frequency of alloimmunization to neoantigens on PLTs;**
- Rate of PLT transfusion-related adverse events (AEs) and serious adverse events (SAE).**
* assessed during Treatment period only, ** assessed during Treatment and follow-up periods |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Haemato-oncological patients with thrombocytopenia or expected to become
thrombocytopenic;
- Expected to receive ≥ 1PLT transfusions during their hospital stay;
- Age ≥ 18 years;
- Written Informed Consent. |
|
E.4 | Principal exclusion criteria |
- Known immunological refractoriness to PLT transfusions, i.e. HLA and/or HPA
alloimmunization (documented in the patient’s medical record);
- History or diagnosis of an autoimmune disease affecting haemostasis;
- Acute or chronic Disseminated Intravascular Coagulation (DIC);
- History or diagnosis of Thrombotic Thrombocytopenic Purpura or Haemolytic Uremic Syndrome;
- Severe uncontrolled infection;

- Previous inclusion in this trial;
- Acute promyelocytic leukemia (AML, FAB subtype M3)
- Active bleeding at time of enrolment requiring one or more RBC transfusions and/or therapeutic platelet transfusions;
- Splenomegaly defined as a palpable spleen felt more than 4 cm below costal margin;
- History of severe anaphylactic transfusion criteria;
- Legal incapacity or other circumstances preventing the patient from understanding the nature, meaning and implications of the clinical Trial. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of the trial is to demonstrate the non-inferiority of UVC-PCs in comparison to untreated or gamma-irradiated platelet concentrates (control PCs) assessed by the 1-hour CCI calculated for each PLT transfusion on a maximum of 8 PLT transfusions, stored for up to 5 days, per patient during the treatment period.
Definition of the non-inferiority value: Up to a 30% reduction in CCI (test Group vs. controll) will be considered as not inferior.

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
On a maximum of 8 PLT transfusions per patient during the treatment period of max. 28 days |
|
E.5.2 | Secondary end point(s) |
- Mean 24-hour CCI, mean 1-hour CI and mean 24-hour CI calculated for each PLT transfusion on a maximum of 8 PLT transfusion;*
- Mean number of PLT transfusion episodes and Units;*
- Mean interval between PLT transfusions (days);*
- Mean number of RBC transfusion episodes and Units;*
- Rate of bleeding events ≥ WHO grade 3 and grade 4;*
- Rate of clinical refractoriness defined as consecutive two consecutive transfusions with 1 hour CCI < 7.5;*
- Rate of immunologic refractoriness defined as consecutive two consecutive transfusions with 1 hour CCI < 7.5 and serologic conversion to positive tests for HLA-and/or HPA alloantibodies or antibodies to UVC-related neoantigens;*
- Frequency of alloimmunization to neoantigens on PLTs**
- Rate of PLT transfusion-related adverse events (AEs) and serious adverse events (SAE).**
* assessed during treatment period only; ** assessed during treatment and follow-up periods
