Study summary

The study team is seeking a novel treatment for snoring involving local application of a nerve stimulant medication, neostigmine. In this study, neostigmine will be injected into 5 sites of the soft palate during a standard procedure, drug-induced sleep endoscopy, to evaluate the effect on snoring.

Read the detailed description

Snoring is a major problem, affecting 40 million Americans. The disease affects patient and partner sleep quality as well as daytime function. Snoring treatment is limited by device compliance (mouth appliance, positive airway pressure) and insurance does not regularly pay for these devices. Surgical treatment for snoring has mixed results. As a result, there is an important need to develop new treatments for snoring.

The study team is seeking a novel treatment for snoring involving local application of a nerve stimulant medication, neostigmine. In this study, neostigmine will be injected into 5 sites of the soft palate during a standard procedure, drug-induced sleep endoscopy, to evaluate the effect on snoring. If successful, development of a topical (non-injectable) version of this drug will be considered, so that the patient can apply him/herself before bedtime.

Terms in these criteria, in plain language(2)

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.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Study arms

  • Experimental
    Drug-induced sleep endoscopy (DISE) with Neostigmine

    Artificial sleep will be induced by intravenous administration of propofol with micro boluses until clinical sleep is achieved with spontaneous respiration and observed apneas under monitored anesthesia care. Endoscopy will be performed with visualization on a monitor and recording on a digital recorder. After the patient demonstrates snoring and obstruction collapse, the patient will receive the study medication (neostigmine methylsulfate 1mg/mL) into the soft palate.

    Drug: Neostigmine Methylsulfate

Interventions

  • After the patient demonstrates snoring and obstruction collapse, the patient will receive the study medication (neostigmine methylsulfate 1mg/mL) into the soft palate with co-administration of intravenous glycopyrrolate 0.2mg. At each of 5 injection sites on the soft palate , 0.5 mL (0.5mg) of neostigmine methylsulfate will be administered, yielding a total of 2.5mg (2.5mL) of neostigmine methylsulfate. The medication will be administered using five 1 mL syringes filled with 0.5 mL neostigmine each. Following administration of neostigmine, the patient will be observed for an additional 4 minutes to examine both vibration and sound emanating from the soft palate. The anticipated time under sedation will be 14 minutes.

What researchers measure

Primary outcomes

  1. Change in decibel sound after injection of neostigmine

    The data will come from the drug-induced sleep endoscopy (DISE) audio and video recordings. Prior to the neostigmine injection, a snoring microphone will be placed over the right clavicle. Following administration of neostigmine, the patient will be observed for an additional 4 minutes to examine sound emanating from the soft palate. Total run time, instantaneous decibel levels, LAeq (average decibel level over time), and the maximum decibel level will be recorded.

    Time frame: The DISE will occur up to 30 days after the pre-op visit and study enrollment

  2. Change in soft palate motion after injection of neostigmine

    The data will come from the drug-induced sleep endoscopy (DISE) audio and video recordings. Following administration of neostigmine, the patient will be observed for an additional 4 minutes to examine vibration emanating from the soft palate.

    Time frame: The DISE will occur up to 30 days after the pre-op visit and study enrollment
