Trial summary

Respiratory recurrent papilloma (RRP) is one of the most common benign tumors. Surgical removal is the current management for RRP, but it is a very traumatic procedure, and often leads to permanent voice dysfunction. Read more about this study

About this study

Official title: Voice-preserving Treatment of Laryngeal Papilloma

Respiratory recurrent papilloma (RRP) is one of the most common benign tumors. Surgical removal is the current management for RRP, but it is a very traumatic procedure, and often leads to permanent voice dysfunction. In this study, we will develop a new, combined RRP treatment with a pulsed dye laser (PDL) and Celebrex. We will determine if Celebrex, a newly developed inhibitor of cyclooxygenase (COX)-2, can provide a long-term inhibitory effect on RRP, therefore preventing RRP from recurring. This combined strategy, if successful in this proposed study, will provide a new and ideal "voice-preserving" therapy for RRP that will deliver long-term efficacy in managing RRP.

Read the detailed description

RRP and its surgeries usually involves the vocal cords or other regions of the larynx, thereby, resulting in a poor voice. Our previous studies have shown the efficacy and safety of a microvascular targeting technique (MVT) for RRP treatment using the 585 nm PDL. This technique provides a less traumatic alternative to surgery. However, postoperative recurrence of lesions still remains a problem because of microvascular regrowth. This study is a continuation of our effort to develop a new and less traumatic treatment for RRP. In this study, we will develop a new, combined RRP treatment with PDL and Celebrex. We will determine if Celebrex, a newly developed inhibitor of COX-2, can provide a long-term inhibitory effect on RRP through its anti-angiogenic activity and the synergic effect produced with the laser therapy. The hypothesis is that postoperative administration of Celebrex will provide a long-term inhibitory effect on microvascular regrowth and on COX-2 enzyme, thereby, preventing RRP from recurring after the PDL therapy. Our specific aim in this study is to determine the synergic effect between PDL and Celebrex and long-term efficacy of Celecoxib in preventing postoperative RRP recurrence. We will compare this new combined strategy with traditional treatments in 30 adult patients. This is the first time to combined this new laser MVT technique with a COX-2 inhibitor for microvascular targeting therapy of RRP. This combined strategy, if successful in this proposed study, will provide a new and ideal "voice-preserving" therapy for RRP that will deliver long-term efficacy in managing RRP and will be safe and convenient enough for use in out-patient treatment.

What is being measured

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

  1. Number of Case With Papilloma Recurrence During a 12-month Follow up

    Criteria for the recurrence: the site scoring >4, plus visible lesion found in >50% of the treated tissue area, after surgery Description: The caculation of the site scoring is based on a called Derkay's scoring system: to indicate how many anatomic site involved, from the 0 (the best)to 13 (the worst),among a total of 13 laryngeal sites such as epiglottis or right true vocal cords.

    Measured: 12-month follow up

Secondary outcomes (1)
  1. Time Course (Month) With Papilloma Recurrence During 12-month Follow up

    The measuer is reported as time course (i.e., how many month) to see papilloma recurrence if there is any such recurrence.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Celebrex, PDL and CO2 laser or microsurgery in people with Laryngeal Papilloma, run by Boston University 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 4 inclusion and 8 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: stopped early, as of the sponsor's last update on 31 Aug 2012. 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 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 24 Aug 2012). 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 Case With Papilloma Recurrence During a 12-month Follow up (time frame: 12-month follow up). 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 31 Aug 2012.
