Study summary

We hypothesize that tissue and salivary pepsin will resolve after 12 weeks use of Reza Band, but not following standard of care alone. Additionally, RFS, RSI and inflammatory cytokines (IL -1β, -6, and -8) will decrease to normative levels following 12 weeks use of Reza Band, but not with standard of care alone.

Primary Objective The primary objective is to evaluate the efficacy of the Reza Band for the treatment of LPR. We propose a pilot clinical trial to test the hypothesis that the Reza Band is effective for the treatment of LPR, measured by resolution of pepsin and decrease to normative values for RSI, Reflux Finding Score (RFS) and inflammatory cytokines.

The long-term goal is to determine the efficacy of the Reza Band in the sequential progression of reflux-attributed laryngeal inflammatory and neoplastic disease.

Read the detailed description

We propose a prospective cohort study. Sixty patients ≥ 18 years of age presenting to our laryngology outpatient clinic with LPR, with an RFS ≥ 7 and an RSI ≥ 13, not on anticoagulants, able to tolerate an endoscopy and consent to participate in this research study will be included. The study will consist of two cohorts. Cohort one will receive standard care (n = 30), and cohort two will receive standard care plus the Reza Band (to be worn as recommended by the manufacturer; n = 30). Patients will be assigned to either of the cohorts, based on their preferences.

Two laryngeal (posterior cricoid) biopsy specimens (one for pepsin ELISA and the other for qPCR for IL -1β, -6, and -8 inflammatory cytokines) and a throat saliva sample (for pepsin ELISA) will be obtained pre- and posttreatment (12 weeks) in an ambulatory clinic setting. The RSI, a patient-reported symptom severity questionnaire, will be administered in the clinic pre- and posttreatment. (36) Patients will be instructed to cough and clear the back of their throat to provide a saliva sample prior to endoscopy. The RFS (37) will be obtained by the study physicians during office endoscopy prior to biopsy. Deidentified biopsy and saliva samples will be transported to the research laboratory on ice and stored at -80 prior to analyses by ELISA and qPCR.

Pepsin ELISA One biopsy per subject will be homogenized in urea lysis buffer and total protein concentration determined as previously described (28). Saliva samples will be cleared by brief centrifugation. Noncompetitive indirect sandwich enzyme-linked immunosorbent assay described previously (35) will be performed to detect pepsin in biopsy homogenate and saliva.

qPCR RNA will be extracted from a second biopsy, DNAsed and reverse transcribed as described (38). Real time polymerase chain reaction will be performed in a Viaa7 Real Time PCR System using Taqman Gene Expression Assays targeting IL -1β, -6, and -8, and the housekeeping gene HPRT1 (ThermoFisher Scientific, Waltham, MA).

This pilot study will pave the way for clinical trials of a much-needed therapy for airway reflux. If the hypothesis proves true and the Reza Band resolves pepsin and inflammatory cytokines, and significantly improves endoscopic signs (RFS) and symptoms (RSI) of LPR, these data will also support a clinical trial to assess the utility of the Reza Band in preventing reflux-attributed laryngeal inflammatory and neoplastic disease sequelae. To our knowledge, this is the first study that will use pepsin as a primary outcome measure; it is believed to be a sensitive and specific biomarker for reflux and aspiration.

Deidentified biopsy and saliva samples will be transported to the research laboratory on ice and stored at -80 degrees C prior to analyses by ELISA and qPCR. The tissue and saliva samples will be labeled with patient study ID number and date of collection.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Clinical diagnosis of laryngopharyngeal reflux (LPR).
  2. Age ≥ 18 years.
  3. Reflux Finding Score (RFS) of ≥ 7 and an Reflux Symptom Index (RSI) ≥ 13.
  4. Patients should be able to tolerate an endoscopy.
  5. Patients must be deemed able to comply with the treatment plan and follow-up schedule.
  6. Enrollment on an interventional postoperative study is allowed if study device/agents do not overlap i.e. no other device or medication for the treatment of LPR is permitted during the duration of this study.
  7. Patients must provide study-specific prior to study entry.

Exclusion criteria

Exclusion Criteria:

  1. Patient should not be on anticoagulants
  2. Currently being treated with another medical device and/or drug.
  3. Currently receiving treatment for sleep apnea with continuous positive airway pressure (CPAP).
  4. The patient is female and is of and is not using an acceptable method of or is pregnant or breast-feeding.
  5. Previous head or neck surgery or radiation.
  6. Carotid artery disease, thyroid disease or history of cerebral vascular disease.
  7. Suspected esophageal cancer.
  8. Has either a pacemaker or implanted cardioverter defibrillator (ICD).
  9. Nasopharyngeal cancer.
  10. Previously undergone Nissen Fundoplication.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Interventions

  • DeviceReza band

    Reza band, a non-medication, non-surgical medical device designed to reduce symptoms of LPR has recently been approved by the FDA. It works by stopping the flow of gastric contents through the upper esophageal sphincter (UES) by increasing the internal pressure of the UES

What researchers measure

Primary outcomes

  1. Change in Tissue and Salivary Pepsin Levels

    The primary objective is to evaluate the efficacy of the Reza Band for the treatment of LPR. We propose a pilot clinical trial to test the hypothesis that the Reza Band is effective for the treatment of LPR, measured by resolution of pepsin and decrease to normative values for RSI, Reflux Finding Score (RFS) and inflammatory cytokines.

    Time frame: The change in Pepsin will be measured pre and post 12 week treatment for LPR +/- Reza band

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 8, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
