NCT03492931

Brief Summary

The purpose of this Phase I study is to investigate the pharmacokinetic properties of ticagrelor in pediatric patients from 0 to less than 24 months with sickle cell disease. Ticagrelor dose level adjustment will require a Protocol amendment and regulatory approval.

Outcome Measures

Primary Outcomes (3)

  • Peak Plasma Concentration (Cmax) of Ticagrelor

    This measure is obtained from observed plasma concentrations

    1,2,4,6 hours post dose

  • Area under plasma concentration curve

    This measure is obtained from the population PK analysis

    1,2,4,6 hours post dose

  • CL/F (Oral clearance)

    This measure is obtained from the population PK analysis.

    1,2,4,6 hours post dose

Secondary Outcomes (3)

  • Peak Plasma Concentration (Cmax) for active metabolite (AR-C124910XX)

    1,2,4,6 hours post dose

  • Area under plasma concentration curve

    1,2,4,6 hours post dose

  • Assessment of ticagrelor suspension for palatability

    Day 1, single timepoint assessment

Study Arms (1)

Treatment arm

EXPERIMENTAL

Single dose of ticagrelor based on age

Drug: Ticagrelor

Interventions

Patients will receive a single dose of ticagrelor

Also known as: AR-C124910XX is an active metabolite of ticagrelor given orally in a single dose. It will be measured, but it won't be given directly to subjects.
Treatment arm

Eligibility Criteria

Age1 Day - 23 Months
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Paediatric patients aged \<24 months, diagnosed with homozygous sickle cell (HbSS) or sickle beta-zero-thalassemia (HbS/β0), as confirmed by high performance liquid chromatography or haemoglobin electrophoresis.
  • Body weight ≥5 kg at the time of screening.
  • If treated with an anti-sickling agent such as hydroxyurea, the weight-adjusted dose must be stable for 3 months before screening/enrolment.
  • Provision of signed and dated written informed consent from parents/legal guardians prior to any study specific procedures not part of standard medical care.

You may not qualify if:

  • History of transient ischaemic attack or cerebrovascular event/accident (ischaemic or haemorrhagic), severe head trauma, intracranial haemorrhage, intracranial neoplasm, arteriovenous malformation, aneurysm, or proliferative retinopathy.
  • Significantly underdeveloped with regards to height, weight or head circumference for age, as judged by the Investigator.
  • Severe developmental delay (eg, cerebral palsy or mental retardation).
  • Receiving chronic treatment (\>3 days/week) with non-steroidal anti-inflammatory drugs (NSAIDs).
  • Receiving chronic treatment with anticoagulants or antiplatelet drugs that cannot be discontinued.
  • Moderate or severe hepatic impairment, defined as laboratory values of alanine aminotransferase (ALT) \>2 × upper limit of normal (ULN), total bilirubin \>2 × ULN (unless judged by the Investigator to be caused by haemolysis), albumin \<35 g/L and international normalised ratio (INR) \>1.4, or symptoms of liver disease (eg, ascites).
  • Renal failure requiring dialysis.
  • Active pathological bleeding or increased risk of bleeding complications according to the Investigator.
  • Haemoglobin \<6 g/dL from test performed at Screening (Visit 1).
  • Platelets \<100 × 10\^9/L from test performed at Screening (Visit 1).
  • Patient considered to be at risk of bradycardic events (eg, known sick sinus syndrome or second or third degree atrioventricular block).
  • Concomitant oral or intravenous therapy with moderate or strong CYP3A4 inhibitors, CYP3A4 substrates with narrow therapeutic indices, or strong CYP3A4 inducers that have not been stopped at least 5 half-lives before dose administration.
  • Patient breastfed by mother who is under treatment of strong CYP3A4 inhibitors,
  • Active untreated malaria. Patients with suspected malaria at Screening (Visit 1) will be tested.
  • Surgical procedure planned to occur during the study including 5 days after ticagrelor administration.
  • +6 more criteria
