Conditions

Lung Transplant

Brief summary

Patients undergoing a lung transplant will be enrolled. All patients will undergo lung transplantation with standard post-operative management, including triple immunosuppression. As soon as the patient is deemed appropriate to take medications via the oral route, they will be converted from IR tacrolimus to Envarsus XR. Patients will be followed per site's standard of care.

Detailed description

Lung transplantation will be performed per standard-of-care techniques. All post-transplant management, including initial triple immunosuppression, will be carried out per standard of care. Once the patient is able to take medications via the oral route, they will be converted to Envarsus XR, which will be maintained for the first year post-lung transplant.

Interventions

Envarsus XR is an FDA-approved drug for the prophylaxis of organ rejection in de novo kidney transplant patients or in kidney transplant patients converted from IR tacrolimus when used with other immunosuppressants. Envarsus XR is a novel extended-release formulation of tacrolimus created using MeltDose technology. Envarsus XR is available in tablet form. It is available in 0.75, 1, and 4 mg tablets.

Historical cohort of 20 subjects who will be maintained on IR tacrolimus following transplant. Dosing will be converted on an individual basis (Capsules: 0.5 mg, 1 mg and 5 mg or Injection: 5 mg) . All patients will be initiated on IR tacrolimus either under the tongue (sublingual) or as a solution given through a tube placed through the nose into the stomach, which is standard of care for all lung transplant recipients.

Participant flow

Pre-assignment details

41 individuals were enrolled to participate in the trial; 1 individual did not begin treatment in the study, thus, only 40 participants started the study. Data on 24 historical control individuals were collected and analyzed retrospectively for the secondary outcome measures, but these 24 individuals were not recruited nor enrolled into the study, thus, they are not reflected in the total Protocol Enrollment figure.
