Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: - To assess the PD properties of a single subcutaneous injection of RUC-4 in STEMI patients presenting to the CCL with the aim to perform primary coronary angioplasty. - To assess the PK properties of a single subcutaneous injection of RUC-4 in STEMI patients presenting to the CCL with the aim to perform primary coronary angioplasty. - To assess safety and tolerability of RUC-4;Secondary Objective: - To assess platelet count at select time points before and after RUC-4 administration - To assess bleeding events* of a single SC injection of RUC-4 at select timepoints after RUC-4 administration, at discharge and at 15-day and at 30-day follow-up - To assess intraprocedural thrombosis - To assess the injection site reactions of a single subcutaneous injection of RUC-4 at select timepoints after RUC-4 administration and at 15-day and at 30-day follow-up - To evaluate any differences in PD or PK within each treatment group (gender, weight, BMI, age) * According to the BARC (II, III and V), ISTH Major and TIMI Major criteria;Primary end point(s): - Inhibition of thrombin receptor activating peptide (TRAP)-induced platelet aggregation (%) assessed by VerifyNow at baseline, and at 15, 45, 60, 90, 120, 180 and 240 minutes after administration of RUC-4 (the 240 minute time point is only applicable if the RUC-4 dose is increased in cohort 2 and/or 3) - RUC-4 concentration (ng/mL) versus time profiles (at baseline and at 15, 45, 90, 120 and 180 minutes after administration of RUC 4) and associated PK parameters - Safety and tolerability parameters at baseline and at hospital discharge;Timepoint(s) of evaluation of this end point: see primary end points (E.5.1) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Platelet count (µL) at baseline, and at 15, 45, 90, 120 and 180 minutes after administration of RUC-4 and at hospital discharge - Bleeding events (according to BARC II, III and V criteria for safety assessment and according to ISTH Major and TIMI Major for information only) at baseline, discharge and at 15-day and 30-day follow-up - Intraprocedural thrombosis (assessed by PI) - Injection site reactions at baseline, 1-hour post-PCI, hospital discharge, and at 15-day and 30-day follow-up - Inhibition of ADP-induced platelet aggregation (%) assessed by VerifyNow at baseline, and at 15, 45, 60, 90, 120, 180 and 240 minutes after administration of RUC-4 (the 240 minute time point is only applicable if the RUC-4 dose is increased in cohort 2 and/or 3) - Differences in PD or PK among the patients (gender, weight, BMI, age);Timepoint(s) of evaluation of this end point: see secondary end points (E.5.2) | — |
