About this study

Official title: A Prospective, Pilot Trial to Evaluate Safety and Tolerability of Tacrolimus Extended-Release (Astagraf XL) in HLA Sensitized Kidney Transplant Recipients

The purpose of this study is to demonstrate the safety of tacrolimus extended-release in HLA sensitized (HS, defined as panel reactive antibody ≥ 30%), kidney transplant recipients after desensitization with intravenous immunoglobulin (IVIG) and rituximab (also known as ritux) +/- plasma exchange (PLEX) per the standard of care with alemtuzumab induction.

Read the detailed description

The study will be a single center, pilot trial. It will be an open label, single-arm, non- controlled design. All HS kidney transplant recipients with Panel Reactive Antibodies (PRA) ≥ 30%, age 18 and older, requiring desensitization may be included in the study. Initial desensitization protocol for living donor (LD) or deceased donor (DD) includes Intravenous Immunoglobulin (IVIG) 2g/kg (>70kg max 140g) given on day 0 (split over 2 days for peritoneal dialysis patients), rituximab 375mg/m2 (rounded to the nearest 100mg vial) given on day 15, and IVIG 2g/kg (>70kg max 140g ) given on day 30. Recipients for LD or DD who are unresponsive to IVIG/ritux (after 2 months for LD and after 6 months for DD) will require PLEX 5-7 sessions followed by IVIG 2g/kg (>70kg max 140g) and rituximab 375mg/m2. Patients will be receiving acetaminophen, antihistamine, and steroid as premedication for all infusions.

A total of 20 subjects will be enrolled in the study. Subjects will take part in the study until they are one year post-transplant. All subjects will require informed consent. At the time of screening, subjects will receive a physical exam and undergo lab testing. Alemtuzumab 30mg, will be administered subcutaneously to all subjects for induction immunosuppression immediately post-transplant. Maintenance immunosuppression will consist of tacrolimus extended-release, mycophenolate mofetil 500mg twice daily or mycophenolate sodium 360mg twice daily, and prednisone. Patients will receive antimicrobial prophylaxis per Cedars-Sinai Medical Center (CSMC) protocol. Lab tests and physical exams for safety will take place according to the evaluation schedule below. Safety will be assessed by the reporting of serious adverse events.

Tacrolimus trough level, complete metabolic panel, liver function panel, complete blood count with differential, Donor Specific Antibodies (DSA), and urinalysis with culture will be assessed according to the evaluation schedule below. Subjects will complete the study at one year post-transplant. Consent may be withdrawn by the study participant at any time. The investigator may also withdraw the study participant at any time if there are any safety concerns.

Desensitization includes Intravenous Immunoglobulin (IVIG) 2g/kg (>70kg max 140g) given on day 0 (split over 2 days for peritoneal dialysis patients), rituximab 375mg/m2 (rounded to the nearest 100mg vial) given on day 15, and IVIG 2g/kg (>70kg max 140g ) given on day 30. Patients will require PLEX 5-7 sessions if they have received desensitization in the past. In this case, patients will receive PLEX daily x 5-7 sessions followed by IVIG 2g/kg (>70kg max 140g) and rituximab 375mg/m2. Patients will be receiving acetaminophen, antihistamine, and steroid as premedication for all infusions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment-related Adverse Events and Treatment Failure

    To determine the safety of tacrolimus extended-release in HS kidney transplant recipients after desensitization with intravenous immunoglobulin (IVIG) and rituximab +/- plasma exchange (PLEX) per the standard of care and alemtuzumab induction. This will be measured by the rate of serious adverse events (SAEs) and treatment failure. Treatment failure is defined as a composite of biopsy proven acute rejection (BPAR), graft failure, or death. BPAR is defined as ≥ Banff 1A using the Banff 2007 criteria.

    Measured: 12 months

Secondary outcomes (2)
  1. Change in Donor Specific Antibodies (DSA) as Defined by the DSA Relative Intensity Score (RIS)

    To observe the change in DSA as defined by the DSA RIS, which is defined by: 0 points for no DSA, 2 points for each weak DSA (MFI <5,000), 5 points for each moderate DSA (MFI 5,000 -10,000), and 10 points for each strong DSA (MFI >10,000).

    Measured: Transplant, 1 month, 3 months, 6 months, 9 months, and 12 months

  2. Tolerability as Defined by the Number of Subjects Discontinuing the Study Medication

    To observe the tolerability as defined by the number of subjects discontinuing the study medication.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Tacrolimus Extended-Release Oral Capsule in people with End Stage Renal Disease, run by Cedars-Sinai Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment-related Adverse Events and Treatment Failure (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jan 2022.
