Exclusion criteria

6-7-8-9) 9. Venous access (both arms) sufficient to allow blood sampling and study drug administration as per protocol. 10. Participants and their partners of childbearing potential \[meaning who are not surgically sterile (tubal ligation/obstruction or removal of ovaries or uterus) or post-menopausal (absence of menstrual periods for at least 12 consecutive months)\] must be willing to use 2 methods of contraception: - a highly effective method of birth control starting at screening. Highly effective methods of birth control are defined as those that result in a low failure rate (i.e. Pearl Index less than 1% per year) when used consistently and correctly, such as implants, rings, patches, injectable or combined oral contraceptives, intrauterine devices (IUDs), or sexual abstinence (periodic abstinence e.g. calendar, ovulation, symptothermal, postovulation methods, declaration of abstinence for the duration of the trial, and withdrawal are not acceptable methods of contraception) . - and a local barrier form of contraception. Acceptable barrier methods are either the participant's use of a condom or the partner's use of an occlusive cap or diaphragm, or spermicides. Participants will not donate sperm from the selection visit and up to 90 days after the infusion. In case of sterile or vasectomised participants, no contraception will be required for their partners of childbearing potential. 11. Willing/able to adhere to the study visit schedule and other requirements, prohibitions and restrictions specified in this protocol.

MeasureTime frameDescription
Measurement of the Safety Lab Parameter Activated Partial Thromboplastin Time (aPTT)At pre-dose (baseline), 2, 4, 6, 8, 12, 24, 48, 72 hours post-dose and at the discharge visit (Day 10 ± 2 days)These safety aPTT results were readily available to the PI for safety follow-up during and after the study drug administration. Safety aPTT was followed up at the bedside at regular time-points (as opposed to the PD biomarker aPTT, which was assessed by the central laboratory alongside the PK time-points). An aPTT ratio was calculated by dividing the aPTT value (in sec) of the specific time-point (aPTTt) by the baseline aPTT value (in sec) (aPTTbaseline) of the same participant (aPTT ratio = aPTTt/aPTTbaseline). The baseline time-point was considered as having an aPTT ratio of 1. Concerning the row titles, for example, Day 1 H02:00 corresponds to aPTT ratio results obtained on Day 1, 2 hours after the start of the infusion.

FXI is the limiting factor and clotting time is inversely proportional to the concentration of FXI. There is an inverse linear relationship between the percentage of FXI activity and the corresponding clotting time. Central laboratory normal ranges for Factor XI activity are between 65 and 150 %. Concerning the row titles, for example, Day 1 H02:00 corresponds to the percentage of FXI activity obtained on Day 1, 2 hours after the start of the infusion.

FXII is the limiting factor and clotting time is inversely proportional to the concentration of FXII. There is an inverse linear relationship between the percentage of FXII activity and the corresponding clotting time. Central laboratory normal ranges for Factor XII activity are between 50 and 150 %. Concerning the row titles, for example, Day 1 H02:00 corresponds to the percentage of FXII activity obtained on Day 1, 2 hours after the start of the infusion.
Measurement of the Effect of Ir-CPI on the Activated Partial Thromboplastin Time (aPTT)Pre-dose (baseline), 0.5, 1, 1.5, 2, 4, 6, 6.5, 7, 7.5, 8, 10, 12, 16, 24, 48, 72, 96 hours post-dose and at the discharge visit (Day 10 ± 2 days)The activated partial thromboplastin time (aPTT) is used as a pharmacodynamic marker. No data were available for the Ir-CPI 1.5 mg/kg group because the results were not usable due to plasma preparation and method repeatability problems. An aPTT ratio was calculated by dividing the aPTT value (in sec) of the specific time-point (aPTTt) by the baseline aPTT value (in sec) (aPTTbaseline) of the same participant (aPTT ratio = aPTTt/aPTTbaseline). The baseline time-point (Day 1 H00:00) was considered as having an aPTT ratio of 1. Concerning the row titles, for example, Day 1 H02:00 corresponds to aPTT ratio results obtained on Day 1, 2 hours after the start of the infusion.

Measurement of the Effect of Ir-CPI on Factor XI Activity

The method is a clotting assay where all the clotting factors are present (constant and in excess, brought by the deficient plasma), excepted for FXI, which is brought by the diluted tested plasma, and clotting is triggered with cephalin, activator and calcium (aPTT). FXI is the limiting factor and clotting time is inversely proportional to the concentration of FXI. There is an inverse linear relationship between the percentage of FXI activity and the corresponding clotting time. Central laboratory normal ranges for Factor XI activity are between 65 and 150 %. Concerning the row titles, for example, Day 1 H02:00 corresponds to the percentage of FXI activity obtained on Day 1, 2 hours after the start of the infusion.

Measurement of the Effect of Ir-CPI on Factor XII Activity

The method is a clotting assay where all the clotting factors are present (constant and in excess, brought by the deficient plasma), excepted for FXII, which is brought by the diluted tested plasma, and clotting is triggered with cephalin, activator and calcium (aPTT). FXII is the limiting factor and clotting time is inversely proportional to the concentration of FXII. There is an inverse linear relationship between the percentage of FXII activity and the corresponding clotting time. Central laboratory normal ranges for Factor XII activity are between 50 and 150 %. Concerning the row titles, for example, Day 1 H02:00 corresponds to the percentage of FXII activity obtained on Day 1, 2 hours after the start of the infusion.

Time frame: Pre-dose (baseline), 0.5, 1, 1.5, 2, 4, 6, 6.5, 7, 7.5, 8, 10, 12, 16, 24, 48, 72, 96 hours post-dose and at the discharge visit (Day 10 ± 2 days)

Population: This analysis was performed on the Pharmacodyamic Set (PDS): all of the included participants who completed the study without any protocol deviation affecting PD evaluation and with at least one available post-baseline PD data point.

Measurement of the Effect of Ir-CPI on the Activated Partial Thromboplastin Time (aPTT)

The activated partial thromboplastin time (aPTT) is used as a pharmacodynamic marker. No data were available for the Ir-CPI 1.5 mg/kg group because the results were not usable due to plasma preparation and method repeatability problems. An aPTT ratio was calculated by dividing the aPTT value (in sec) of the specific time-point (aPTTt) by the baseline aPTT value (in sec) (aPTTbaseline) of the same participant (aPTT ratio = aPTTt/aPTTbaseline). The baseline time-point (Day 1 H00:00) was considered as having an aPTT ratio of 1. Concerning the row titles, for example, Day 1 H02:00 corresponds to aPTT ratio results obtained on Day 1, 2 hours after the start of the infusion.

Time frame: Pre-dose (baseline), 0.5, 1, 1.5, 2, 4, 6, 6.5, 7, 7.5, 8, 10, 12, 16, 24, 48, 72, 96 hours post-dose and at the discharge visit (Day 10 ± 2 days)

Population: This analysis was performed on the Pharmacodyamic Set (PDS): all of the included participants who completed the study without any protocol deviation affecting PD evaluation and with at least one available post-baseline PD data point.
