Trial summary

Antibody mediated rejection (AMR) post transplant contributes to poor long term outcomes after lung transplantation. Additionally, high antibodies detected pre transplant in candidates limit donor availability for lung transplant. This proposal would include belatacept in a multi-therapy regimen.

About this study

Official title: Lung Transplant Plasmapheresis (PLEX)/Belatacept/Carfilzomib Protocol for Treatment of Antibody Mediated Rejection (AMR) and Desensitization

Antibody mediated rejection (AMR) post transplant contributes to poor long term outcomes after lung transplantation. Additionally, high antibodies detected pre transplant in candidates limit donor availability for lung transplant. This proposal would include belatacept in a multi-therapy regimen. Open label study with two patient cohorts for safety and efficacy of belatacept in a multi-modal protocol. The two patient cohorts are an AMR post-transplant cohort and pre-transplant desensitization cohort. A total of 10 patients will be enrolled.The primary objection is drug tolerability and secondary objectives are antibody measurements and allograft function.

Antibody mediated rejection (AMR) post transplant contributes to poor long term outcomes after lung transplantation. Additionally, high antibodies detected pre transplant in candidates limit donor availability for lung transplant. Multimodal therapies with rituximab, intravenous immunoglobulin, plasmapheresis and proteasome inhibitors have not significantly altered the antibodies in these patients. Belatacept targets the T and B cell interaction such that it represents a novel therapeutic strategy. This proposal would include belatacept in a multi-therapy regimen.

This is an open label study with two patient cohorts for safety and efficacy of belatacept in a multi-modal protocol. The two patient cohorts are an AMR post-transplant cohort and pre-transplant desensitization cohort. A total of 10 patients will be enrolled.The primary objection is drug tolerability and secondary objectives are antibody measurements and allograft function.

Being tested
Belatacept, Carfilzomib

Receives: Drug: Belatacept; Drug: Carfilzomib

What is being measured

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

  1. Occurrence of drug side effects

    Drug tolerability with respect to freedom from drug side effects measured using descriptive statistics

    Measured: Within 28 days of last administration of study drugs

  2. Occurrence of infection

    Drug tolerability with respect to freedom from infection measured using descriptive statistics

    Measured: Within 28 days of last administration of study drugs

  3. Occurrence of malignancy

    Drug tolerability with respect to freedom from malignancy measured using descriptive statistics

    Measured: Within 28 days of last administration of study drugs

Secondary outcomes (7)
  1. Number of subjects in the AMR cohort with resolution of at least one donor specific human leukocyte antigen (HLA) antibody (DSA)

    Descriptive statistical report of number of subjects who had resolution of at least one DSA measured by absolute Mean Fluorescent Intensity (MFI) change and log change using pre and post treatment values for each antibody.

    Measured: Within 4 weeks of completion of treatment

  2. Number of subjects in the AMR cohort with improvement or stabilization of lung function as measured by spirometry data

    Pulmonary function (spirometry) data will track forced vital capacity (FVC), forced expiratory volume (FEV1) and forced expiratory flow (FEF) 25-75%. Changes in spirometry will be reported as stabilized, improved or worsened based on comparison of baseline spirometry values obtained prior to treatment plan with serial spirometric testing performed at specified intervals in treatment plan.

    Measured: Within 4 weeks of completion of treatment

  3. Number of subjects in the AMR cohort with improvement in oxygenation as measured by Liters/min oxygen at rest

    Gas exchange will be reported as no change, worsening exchange or improving exchange based on comparison of resting oxygen requirements before and following treatment plan.

    Measured: Within 4 weeks of completion of treatment

  4. Number of subjects in the AMR cohort with decrease in DSA by one log

    Descriptive statistical report of number of subjects who had a decrease in DSA measured by absolute Mean Fluorescent Intensity (MFI) change and log change using pre and post treatment values for each antibody.

    Measured: Within 4 weeks of completion of treatment

  5. Number of subjects in the AMR cohort with elimination of DSA at 1:16 dilution

    Descriptive statistical report of number of subjects who had elimination of DSA at 1:16 dilution measured by absolute Mean Fluorescent Intensity (MFI) change and log change using pre and post treatment values for each antibody.

    Measured: Within 4 weeks of completion of treatment

  6. Number of subjects in the transplant desensitization cohort with decrease in non-DSA HLA antibodies by one log

    Descriptive statistical report of number of subjects who had a decrease in non-DSA HLA antibodies measured by absolute Mean Fluorescent Intensity (MFI) change and log change using pre and post treatment values for each antibody.

    Measured: Within 4 weeks of completion of treatment

  7. Number of subjects in the transplant desensitization cohort with elimination of non-DSA HLA antibodies at 1:16 dilution

    Descriptive statistical report of number of subjects who had elimination of non-DSA HLA antibodies at 1:16 dilution measured by absolute Mean Fluorescent Intensity (MFI) change and log change using pre and post treatment values for each antibody.

    Measured: Within 4 weeks of completion of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Belatacept and Carfilzomib in people with Lung Transplant Rejection and Antibody-mediated Rejection, run by Duke University.

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 16 inclusion and 0 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: withdrawn, as of the sponsor's last update on 2 May 2019. Status can change between updates, so confirm with the study contact before making plans.

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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Occurrence of drug side effects (time frame: Within 28 days of last administration of study drugs). The study lists 3 primary outcomes in all. 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 2 May 2019.
