About this study

Official title: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Multiple Dose Study of the Safety, Tolerability and Population Pharmacokinetics of CMX001 in Post-Transplant Subjects With BK Virus Viruria

This was a randomized, double-blind, multiple-dose placebo-controlled study of oral brincidofovir (BCV) in hematopoietic stem cell transplant and renal transplant recipients with BK virus viruria.

Read the detailed description

This was a randomized, double-blind, multiple-dose placebo-controlled study of oral brincidofovir (BCV) in hematopoietic stem cell transplant and renal transplant recipients with BK virus infection.

Subjects received blinded study medication for a total of 5 doses in 1 of the following regimens:

  • 10 mg BCV administered twice weekly (BIW) on Days 0, 3, 7, 10, 14.
  • 20 mg BCV administered once weekly (QW) on Days 0, 7, and 14 and placebo administered on Days 3 or 10.
  • Placebo administered BIW on Days 0, 3, 7, 10 ,14.
  • 40 mg BCV administered QW on Days 0, 7, 14, 21, and 28.
  • Placebo administered QW on Days 0, 7, 14, 21, and 28.

What is being measured

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

  1. Number of Adverse Events in Post-Transplant Patients With BK Virus Viruria

    The primary objective of this study was to determine the safety and tolerability of brincidofovir (BCV) in post-transplant patients with BK virus viruria. Safety measures included adverse events, clinical laboratory values, vital signs, and renal and gastrointestinal function.

    Measured: 35 days (Day 0 to Day 35)

Secondary outcomes (2)
  1. Percentage of Patients Who Achieved BK Viruria Resolution

    The percentage of subjects who cleared the virus was calculated. Concentrations below the lower limit of quantification were indicated as below the limit of quantitation and were considered "cleared".

    Measured: 28 days

  2. Number of Patients Who Achieved a Clinically Significant Decrease in BK Viruria

    A 2-log drop in viruria or viremia or clearance of virus was considered significant. Percentages of subjects with a 2-log drop in viral load were calculated.

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Brincidofovir in people with Viruria, run by Jazz Pharmaceuticals at 15 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 16 inclusion and 21 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 16 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 16 Jul 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 Adverse Events in Post-Transplant Patients With BK Virus Viruria (time frame: 35 days (Day 0 to Day 35)). 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 16 Aug 2021.
