About this study

Official title: Bevacizumab Versus Cidofovir for the Treatment of Recurrent Respiratory Papillomatosis: a Randomized, Double-blind, Placebo-controlled Clinical Trial

The aim of this study is to compare the efficacy of intralesional bevacizumab, a monoclonal antibody against vascular endothelial growth factor, versus the antiviral drug cidofovir in patients with recurrent respiratory papillomatosis.

Read the detailed description

The investigators designed a randomized, double-blind, placebo-controlled study. Children and adults will be randomized to receive either 3 dosis of intralesional bevacizumab, cidofovir or saline solution. Primary endpoints are the assessment of changes in the annual surgery rate and Derkay papilloma severity grading scale; secondary endpoints are changes in the Voice Handicap Index and safety.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BevacizumabDrug

    Also called Avastin

    Patients will receive 3 intralesional injections of bevacizumab (Avastin, Genentech, San Francisco, California) every 3 to 6 weeks in a submucosal plane after surgical debulking. 12.5 mg of bevacizumab diluted in 3mL of 9% isotonic sodium chloride solution will be injected intralesionally using a 25 gauge.

  • CidofovirDrug

    Also called Vistide

    Patients will receive 3 intralesional injections of cidofovir every 3 to 6 weeks a submucosal plane after surgical debulking. 3.5 mL of cidofovir diluted to a concentration of 5 mg/mL in a 9% isotonic sodium chloride solution will be injected intralesionally using a 25 gauge.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Bevacizumab and Cidofovir in people with Recurrent Respiratory Papillomatosis, run by Centro de Investigación en. Enfermedades Infecciosas, Mexico at 1 site in Mexico.

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 2 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 26 Jul 2016. 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 Mexico. 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 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?

Results are not available in the source record.

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

Contact Yuria Ablanedo-Terrazas, M.D. (+525556667985, yuria.ablanedo@cieni.org.mx), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in the annual surgery rate (time frame: 12 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02555800, which also lists 1 linked publication.

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 26 Jul 2016.
