About this study

Official title: Voice Preserving Therapy of Laryngeal Papilloma In Children

This study will determine efficacy of a new and combined treatment of laryngeal recurrent respiratory papillomatosis (RRP), by using a 585 nm pulsed dye laser (PDL) and a dietary supplement, diindolylmethane (DIM). We will compare this new treatment with PDL-only, in a total of 30 children (15 of each treatment), to determine whether this combined treatment would be effective and safe in preventing the RRP recurrence. This is the first study to combine PDL technique with DIM, to develop a new, voice-preserving and long-term effective method of managing laryngeal RRP in children.

Read the detailed description

Previous studies have demonstrated that PDL can be used to remove lesions on the vocal cords and elsewhere in the throat causing less damage to surface tissues than other commonly used lasers. In our proposed clinical study, we seek to compare treatment efficacy for RRP by combining PDL with DIM, versus PDL-only treatment, in a total of 30 children with laryngeal papilloma. We will determine whether this combined treatment would be effective and safe in preventing or delaying the RRP recurrence while preserving voice quality. 30 children will be divided randomly into two treatment groups, 15 in each. The experimental group will receive one-time PDL treatment, followed by 3-month oral administration of DIM and an additional 12 months with no treatment. The other group will be treated with PDL-only, as a control, and take a placebo pill for 3 months. All of the patients will be followed for a total of 15 months. We will compare lesion recurrence and laboratory tests between the two groups, to determine efficacy and safety of the new treatment. This is the first study to combine new PDL laser technique with DIM, to develop a new, voice-preserving and long-term effective method of managing laryngeal RRP in children.

What is being measured

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

  1. Number of Cases With Recurrence of Laryngeal Papilloma in 5 Months

    vocal lesion size and area after 5 month with surgery visible lesion found in >50% of the treated tissue area, after surgery

    Measured: Recurrence of pailloma at 5 months

Secondary outcomes (2)
  1. Estradiol Level in Blood Pre Treatment

    determine side-effect by comparing Estradiol level in blood before and after treatment

    Measured: Before treatment at baseline

  2. Estradiol Level in Blood Post Treatment

    determine side-effect by comparing Estradiol level in blood before and after treatment

    Measured: 5 month

Questions about this trial

What is this clinical trial studying?

A study testing diindolylmethane (DIM) and 585 nm pulsed dye laser in people with 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 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: stopped early, as of the sponsor's last update on 18 May 2017. 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. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 May 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?

Number of Cases With Recurrence of Laryngeal Papilloma in 5 Months (time frame: Recurrence of pailloma at 5 months). 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 18 May 2017.
