Study summary

The goal of this study is to find out if a drug called selatogrel (ACT-246475) can prevent platelets from binding together when administered by an injection under the skin in the thigh or in the belly. Another goal is to know how fast and for how long selatogrel (ACT-246475) works and if there is a difference if the drug is injected in the thigh or in the belly. This study will also help to find out more about the safety of this new drug.

Read the detailed description

To investigate the pharmacodynamic (PD) and pharmacokinetic (PK) properties of selatogrel in patients with atherosclerotic disease, the present study will be conducted in patients with chronic coronary syndromes (CCS). Assessment in a population of patients with CCS allows better control and stability of concomitant treatments, and therefore more accurate characterization of the pharmacodynamic and pharmacokinetic profiles of selatogrel in the presence of background antiplatelet therapies.

The study will have 3 periods: a screening period of up to 21 days prior to randomization, a treatment period of 2 days from randomization (Day 1) to 24 hours post dose (Day 2), and a follow-up period from Day 3 to the safety follow-up telephone call 28 to 35 days after single administration of study drug (End-of-Study).

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

What researchers measure

Primary outcomes

  1. Number of Participants With a Pharmacodynamic Response as Assessed by the Inhibition of Platelet Aggregation

    The pharmacodynamic response was determined by measuring the inhibition of platelet aggregation, using VerifyNow®. The VerifyNow® is a point-of-care test measuring platelet reactivity. The results are expressed as P2Y12 reaction units (PRU). The target of 100 PRU corresponds to 80% inhibition of ADP-induced platelet aggregation. A participant with a PRU of less than 100 starting from 30 minutes after the administration of study treatment and lasting for at least 3 hours was considered a "responder".

    Time frame: From 15 minutes after administration of the subcutaneous injection up to 24 hours

Secondary outcomes

  1. Maximum Selatogrel Plasma Concentration (Cmax)

    The Cmax is the peak concentration of selatogrel in the plasma after subcutaneous injection. The pharmacokinetic parameters of selatogrel (ACT-246475) were derived by non-compartmental analyses of the plasma concentration-time profiles.

    Time frame: Pre-dose, and from 15 minutes after administration of the subcutaneous injection up to 24 hours

  2. Time to Reach Maximum Selatogrel Plasma Concentration (Tmax)

    Time after subcutaneous injection to reach the maximum observed selatogrel plasma concentration (Cmax).

    Time frame: Pre-dose, and from 15 minutes after administration of the subcutaneous injection up to 24 hours

  3. Area Under the Plasma Concentration-time Curve of Selatogrel From Time Zero to 24 Hour Time Point (AUC0-24)

    The area under the plasma concentration-time curve is the integral of the concentration-time curve after subcutaneous injection of selatogrel. The plasma pharmacokinetic parameters of selatogrel (ACT-246475) were derived by non-compartmental analyses of the plasma concentration-time profiles.

    Time frame: Pre-dose, and from 15 minutes after administration of the subcutaneous injection up to 24 hours post-dose

Other outcomes

  1. Number of Participants With a Pharmacodynamic Response as Assessed by the Inhibition of Platelet Aggregation by Site of Treatment Administration (Thigh or Abdomen)

    The inhibition of platelet aggregation based on the route of administration, i.e. whether the pharmacodynamic response was different if selatogrel was administered subcutaneously in the thigh or in the abdomen, was analyzed. The pharmacodynamic response was determined by measuring the inhibition of platelet aggregation, using VerifyNow®. The VerifyNow® is a point-of-care test measuring platelet reactivity. The results are expressed as P2Y12 reaction units (PRU). The target of 100 PRU corresponds to 80% inhibition of ADP-induced platelet aggregation. A participant with a PRU of less than 100 starting from 30 minutes after the administration of study treatment and lasting for at least 3 hours was considered a "responder".

    Time frame: From 15 minutes after administration of the subcutaneous injection up to 24 hours

  2. Number of Participants With a Pharmacodynamic Response as Assessed by the Inhibition of Platelet Aggregation - Sensitivity Analysis

    To assess the robustness of results for the pharmacodynamic response, the main analysis was repeated for the per protocol participants. The pharmacodynamic response was determined by measuring the inhibition of platelet aggregation, using VerifyNow®. The VerifyNow® is a point-of-care test measuring platelet reactivity. The results are expressed as P2Y12 reaction units (PRU). The target of 100 PRU corresponds to 80% inhibition of ADP-induced platelet aggregation. A participant with a PRU of less than 100 starting from 30 minutes after the administration of study treatment and lasting for at least 3 hours was considered a "responder".

    Time frame: From 15 minutes after administration of the subcutaneous injection up to 24 hours

  3. Change From Baseline in Maximum Platelet Aggregation (MPA) as Measured by Light Transmission Aggregometry (LTA)

    Light transmission aggregometry was used as complementary method to the VerifyNow® to evaluate the effect of selatogrel on platelet aggregation. Platelet aggregation was triggered by addition of Adenosine diphosphate (ADP) 20 µM (micromole per liter) and monitored over 6 minutes. Maximum Platelet Aggregation (MPA) to 20 μM ADP was assessed by light transmission aggregometry (LTA), an assay that measures platelet aggregation by determining the amount of light transmitted through a cuvette containing platelet-rich plasma stimulated with 20 µM ADP, relative to platelet-poor plasma (100% light transmittance). A lower MPA % reflects stronger platelet inhibition, whereas a higher MPA % reflects weaker inhibition.

    Time frame: Pre-dose, and from 30 minutes after administration of the subcutaneous injection up to 8 hours

  4. Number of Participants With Bleeding Events

    Treatment-emergent adverse events in the category "Haemorrhage (excluding laboratory terms)" were of special interest and their incidence listed below. The role of the Independent Safety Event Committee was to monitor unblinded safety data obtained in the study, with a specific focus on study-drug-related clinically relevant major bleeding events, occurring within 48 hours after dosing (i.e. the treatment period).

    Time frame: From study treatment administration on Day 1 up to 48 hours
