CDx Biopsies for Detection of Laryngopharyngeal Reflux and Laryngeal Lesions

July 16, 2020 updated by: CDx Diagnostics
The study will take place at Rambam medical center, department of Otolaryngology Head and Neck Surgery, for two years. Patients suspected of LPR or laryngeal l tumor and are candidate for laryngeal or hypopharyngeal biopsies will be recruited.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

First- all patients visiting our clinic with laryngeal complaints suspicious for either LPR or laryngeal tumor will fill the RSI questionnaire. Then fiberoptic examination will be performed by a laryngologist that will complete the RFS score.

Patients with suspicious lesions will be referred for TFL standard biopsy and CDx brush biopsy in order to determine whether the lesions are malignant or benign. The pathologic diagnosis of invasive carcinoma from a TFL biopsy is considered equivalent to the pathology results from a direct laryngoscopy biopsy. All patients with benign pathology or carcinoma in-situ (CIS) on TFL biopsy will be referred for subsequent direct laryngoscopy (DL) for definitive diagnosis. At the time of the DL biopsy will include also another CDx brush smear. Patients with benign-appearing lesions will be taken for lesion removal and biopsy.Before removal of the lesion a CDx brush smear will be collected.

All the participants suspected of LPR will have: PHmetry with Manometry andCDx brush biopsy.All relevant demographic and clinical data will be retrieved for analysis.

CDx biopsies will be an addition to the routine management of the patients in the diagnosis and follow-up of laryngeal lesions and LPR and will not replace the standard regimen.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age 18 or over
  • patients suspected to suffer from LPR
  • Patients with laryngeal/hypopharyngeal lesions.

Exclusion Criteria:

  • Patient refusal
  • Patients with anatomical variants which precludes biopsy taking.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Brush biopsy for laryngeal lesion
Brush biopsy of the larynx - in addition to the standard biopsy
Device: Endo CDx Brush biopsy
In patients with laryngeal lesion the brush biopsy will be taken with the standard cup biopsy - either in the clinic or in the OR. In LPR patients brush biopsy will be taken in the clinic.
EXPERIMENTAL: Brush biopsy for LPR
Brush biopsy of the larynx at the post cricoid region - in addition to the standard examination for LPR (PH monitoring double probe)
Device: Endo CDx Brush biopsy
In patients with laryngeal lesion the brush biopsy will be taken with the standard cup biopsy - either in the clinic or in the OR. In LPR patients brush biopsy will be taken in the clinic.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Efficacy of EndoCDx brush
Time Frame: 3 months
Efficacy of EndoCDx brush biopsy as a diagnostic tool for laryngeal lesions compared to cup forceps biopsy and a diagnostic tool for LPR compared to double probe PH monitoring
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assessment of pain
Time Frame: 6 months
Assessment of pain during EndoCDx brush biopsy under local anesthesia by Visual Analog Score for pain
6 months

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ANTICIPATED)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
