Outcome Measures

Primary Outcomes (2)

  • Apixaban area under the plasma concentration curve between 0 and 72 hours (AUC(0-72)).

    Blood samples for Apixaban pharmacokinetics will be collected prior to apixaban administration at 0H, and then at 1, 2, 3, 4, 6, 12, 24, 48 and, 72 hours in each treatment arm

    Days 1-3

  • Apixaban peak plasma concentration (Cmax)

    Blood samples for Apixaban pharmacokinetics will be collected prior to apixaban administration at 0H, and then at 1, 2, 3, 4, 6, 12, 24, 48 and, 72 hours in each treatment arm.

    Days 1-3

Secondary Outcomes (2)

  • Safety and tolerability of Apixaban when co-administered with cyclosporine assessed by capturing incidence of adverse events

    Days 1-4

  • Safety and tolerability of Apixaban when co-administered with tacrolimus assessed by capturing incidence of adverse events

    Days 1-4

Other Outcomes (4)

  • Differences in area under the plasma concentration curve between 0 and 72 hours AUC (0-72)) in kidney and lung transplant recipients

    Days 1-3

  • Differences in peak plasma concentration (Cmax) hours between kidney and lung transplant recipients

    Days 1-3

  • Differences in area under the plasma concentration curve between 0 and 72 hours AUC(0-72)) between transplant recipients and healthy subjects

    Days 1-3

  • +1 more other outcomes

Study Arms (4)

Treatment group A: Cyclosporine in transplant recipients

EXPERIMENTAL

A single oral dose of 10 mg apixaban will be administered to kidney or lung transplant recipients stabilized on cyclosporine as part of their immunosuppressive regimen

Drug: Apixaban

Cyclosporine in healthy subjects

ACTIVE COMPARATOR

Results from Treatment group A will be compared to previously obtained data in healthy participants receiving a single dose of apixaban with a daily dose of 100 mg of cyclosporine at steady state concentration (Bashir et al. Clin Transl Sci. 2018 Jul 3. doi: 10.1111/cts.12580) Transplant recipients require continuous immunosuppression so it will not be possible to stop the cyclosporine or tacrolimus to serve as a control. As such PK plasma time curves will be compared to data in healthy volunteers.

Drug: Apixaban

Treatment group B: Tacrolimus in transplant recipients

EXPERIMENTAL

A single oral dose of 10 mg apixaban will be administered to kidney or lung transplant recipients stabilized on tacrolimus as part of their immunosuppressive regimen

Drug: Apixaban

Tacrolimus in healthy subjects

ACTIVE COMPARATOR

Results from Treatment group B will be compared to previously obtained data in healthy participants receiving a single dose of apixaban with a daily dose of 100 mg of tacrolimus at steady state concentration (Bashir et al. Clin Transl Sci. 2018 Jul 3. doi: 10.1111/cts.12580) Transplant recipients require continuous immunosuppression so it will not be possible to stop the cyclosporine or tacrolimus to serve as a control. As such PK plasma time curves will be compared to data in healthy volunteers.

Drug: Apixaban

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Kidney or lung transplant patients followed as outpatients who are currently stabilized on immunosuppressive therapy with tacrolimus or cyclosporine
  • Age 18 or older
  • At least six months after transplantation
  • Lack of transplant rejection within the last 12 weeks
  • Creatinine clearance at least above 15ml/min as calculated by Cockroft-Gault formula
  • Negative urine pregnancy test for female patients of childbearing potential
  • Consent to the study
  • Be a nonsmoker for at least approximately 6 months prior to the study
  • Have a prothrombin time (PT) and activated partial thromboplastin time (PTT) level below the upper limit of normal
  • Have a hemoglobin level of above at least 80g/L
  • Be willing to refrain from the use of anticoagulants and antiplatelet medications including aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) for two weeks prior and during the entire period of study participation
  • Be willing to avoid drinking grapefruit juice or consuming natural health products for two weeks prior and during the study period
  • Be willing to avoid alcohol and cannabis for 48 hours before the study and for the entire duration of the study
  • Be willing to comply with trial restrictions
  • Be deemed safe to participate by the study physician

You may not qualify if:

  • Patients on antiplatelet therapy for any cardiovascular treatment (such as clopidogrel, prasugrel, ticagrelor). Patients on prophylactic aspirin will be eligible otherwise.
  • Patients not receiving tacrolimus or cyclosporine
  • A history of an anaphylactic or severe systemic reactions to apixaban
  • Any form of substance abuse or major untreated psychiatric disorder
  • Pregnancy or lactation
  • Tacrolimus or cyclosporine changes within the last two weeks
  • Receiving concurrent therapy with warfarin, or are taking medications known to be strong inhibitors of both cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp) such as azole-antimycotics antifungals (e.g., ketoconazole, voriconazole.)
  • Has congenitial or acquired coagulation disorders
  • Has moderate or severe hepatic disease or other clinically relevant bleeding risk
  • Use of any drugs or products which at the discretion of the investigator would increase bleeding risk
  • Has any unstable medical condition that could interfere with the study
  • Is considered inappropriate for participation by the investigator for any reason
  • Clinically significant active bleeding, including gastrointestinal bleeding
  • Lesions or conditions at increased risk of clinically significant bleeding, e.g., recent cerebral infarction (ischemic or hemorrhagic), active peptic ulcer disease with recent bleeding, patients with spontaneous or acquired impairment of hemostasis
  • Patients who donate blood within 56 days of participating in the study
