What is being measured

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

  1. Maximum Observed Serum Concentration (Cmax) of Belatacept

    Cmax was derived from serum concentration versus time data. Serum samples were analyzed for abatacept by a validated enzyme-linked immunosorbent assay (ELISA) and were obtained at: pre-dose (0 hours), 0.5 and 2 hours from Start of Infusion on Day 1, Day 29, and Day 57. The results were summarized. The lower limit of assay quantitation (LLOQ) was set to "zero" which was 0.003 micrograms per milliliter (ug/mL). Cmax was measured in micrograms per milliliter.

    Measured: Pre-dose (0), 0.5hr and 2hr from the start of infusion on Day 1, Day 29, and Day 57

  2. Time of Maximum Observed Plasma Concentration (Tmax) of Belatacept

    Tmax was derived from serum concentration versus time data. Serum samples were analyzed for abatacept by a validated enzyme-linked immunosorbent assay (ELISA) and were obtained at: pre-dose (0 hours), 0.5 and 2 hours from Start of Infusion on Day 1, Day 29, and Day 57. The results were summarized. The lower limit of assay quantitation (LLOQ) was set to "zero" which was 0.003 micrograms per milliliter (ug/mL). Tmax was measured in hours (h).

    Measured: Pre-dose (0), 0.5hr and 2hr from the start of infusion on Day 1, Day 29, and Day 57

  3. Half-Life of Elimination (T-Half) of Belatacept

    T-HALF was derived from serum concentration versus time data. Serum samples were analyzed for abatacept by a validated enzyme-linked immunosorbent assay (ELISA) and were obtained at: pre-dose (0 hours), 0.5 and 2 hours from Start of Infusion on Day 1, Day 29, and Day 57. The results were summarized. The lower limit of assay quantitation (LLOQ) was set to "zero" which was 0.003 micrograms per milliliter (ug/mL). T-HALF was measured in hours (h).

    Measured: Pre-dose (0), 0.5hr and 2hr from the start of infusion on Day 1, Day 29, and Day 57

  4. Area Under the Serum Concentration-time Curve From Time Zero to the Time of the Last Quantifiable Concentration (AUC (0-T)) and Area Under the Serum Concentration-time Curve From Time Zero Extrapolated to Infinite Time (AUC(INF)) of Belatacept

    AUC (0 - T) and AUC (0 - INF) were derived from serum concentration versus time data and measured in microgram hours per milliliter (µg*h/mL). Serum samples were analyzed for abatacept by a validated enzyme-linked immunosorbent assay (ELISA) and were obtained at: pre-dose (0 hours), 0.5 and 2 hours from Start of Infusion on Day 1, Day 29, and Day 57. The results were summarized. The lower limit of assay quantitation (LLOQ) was set to "zero" which was 0.003 micrograms per milliliter (ug/mL).

    Measured: Pre-dose (0), 0.5hr and 2hr from the start of infusion on Day 1, Day 29, and Day 57

  5. Total Body Clearance (CLT) of Belatacept

    CLT was the volume of abatacept cleared by the system, normalized by baseline body weight. Serum samples were analyzed for abatacept by a validated enzyme-linked immunosorbent assay (ELISA) and were obtained at: pre-dose (0 hours), 0.5 and 2 hours from Start of Infusion on Day 1, Day 29, and Day 57. The results were summarized. The lower limit of assay quantitation (LLOQ) was set to "zero" which was 0.003 micrograms per milliliter (ug/mL). CLT was measured in milliliters per hours per kilogram of body weight (mL/h/kg).

    Measured: Pre-dose (0), 0.5hr and 2hr from the start of infusion on Day 1, Day 29, and Day 57

  6. Volume of Distribution at Steady-state (Vss) of Belatacept

    Vss was derived from serum concentration versus time data. Serum samples were analyzed for abatacept by a validated enzyme-linked immunosorbent assay (ELISA) and were obtained at: pre-dose (0 hours), 0.5 and 2 hours from Start of Infusion on Day 1, Day 29, and Day 57. The results were summarized. The lower limit of assay quantitation (LLOQ) was set to "zero" which was 0.003 micrograms per milliliter (ug/mL). Vss was measured in liters per kg body weight (L/kg).

    Measured: Pre-dose (0), 0.5hr and 2hr from the start of infusion on Day 1, Day 29, and Day 57

Secondary outcomes (3)
  1. Number of Participants With Death, Serious Adverse Events (SAEs), and Treatment-related Adverse Event (AE)

    Death was a fatal event leading to permanent cessations of all vital functions of the body. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Adverse event (AE) defined: any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. Treatment related=having certain, probable, possible, or missing relationship to study drug.

    Measured: Date of First Dose to 24 weeks post the last dose; approximately 26 weeks

  2. Number of Participants With Positive Belatacept-induced Immunogenicity Response

    Serum samples were analyzed for anti-belatacept antibodies using a validated homogenous bridging assay. The assay followed a tiered approach consistent with health authority guidance: tier 1 for screening ADA responses, tier 2 for confirming drug specificity of the ADA-positive responses, and tier 3 for titer. A neutralizing antibody assay was used to test those samples positive to the LEA29Y portion of the molecule in tier 2 and for which drug concentrations are =>1 μg/mL. Lack of immunogenicity was defined as the absence of a positive response.

    Measured: Baseline/Day 1, Days 15, 29, and 57

  3. Percentage of CD86 Receptor Occupancy

    Blood samples collected following the single dose belatacept infusion were assessed for CD86 receptor occupancy (CD86 RO).

    Measured: 0.5 hours post dose on Day 1, Day 29 and Day 57

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Belatacept in people with Kidney Transplant, run by Bristol-Myers Squibb at 8 sites 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 10 inclusion and 5 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 24 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites 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 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?

Yes. Results are posted in the registry (first posted 26 Jun 2017). 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?

Maximum Observed Serum Concentration (Cmax) of Belatacept (time frame: Pre-dose (0), 0.5hr and 2hr from the start of infusion on Day 1, Day 29, and Day 57). The study lists 6 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 24 Jul 2017.
