About this study

Official title: A 3-arm Randomized Controlled Study Comparing Ultrasound-guided Cryoablation, Ultrasound-guided Perineural Lidocaine and Ultrasound-guided Perineural Saline to Treat Intermetatarsal Neuroma

The purpose of this study is to evaluate the effectiveness of a device that delivers freezing temperature compared to injecting lidocaine (an anesthetic medication) in providing pain relief to patients with disorganized nerve bundle between the toes, also known as Morton's neuroma. The same ultrasound technology that the obstetricians use to visualize a fetus inside a pregnant woman will be used to help the study physician to locate the Morton's neuroma while precisely delivering the freezing temperature and lidocaine near the nerve.

Read the detailed description

This study will be a 3-arm randomized single-blinded placebo controlled study in which human subjects with intermetatarsal neuralgia will receive subcutaneous normal saline or subcutaneous lidocaine or ultrasound guided cryoablation. The first follow up will take place 4 weeks post procedure to monitor the magnitude and duration of pain relief. Subjects will then be crossed over. Those who had received saline or lidocaine will receive ultrasound guided cryoablation. Individuals, who had previously been given ultrasound guided cryoablation without any improvement, may opt for another denervation procedure at 4 weeks. All of the participants will be followed up at 3 months post procedure to determine the magnitude and duration of pain relief.

Study procedures will be conducted by the principle investigator who is a Board Certified pain management attending physician and an expert in performing ultrasonography guided interventions The cryoablation device is routinely used to treat various painful pathologies at Mount Sinai and Beth Israel pain management offices. The device manual and instructions will be available at both locations. All research staff has prior experience working with individuals with foot and ankle injuries at Mount Sinai.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CryoablationDevice

    Also called Iovera

    A minimally invasive cryoablation device. It delivers focused nitrous oxide to the target tissue via a 22-gauge needle to create an approximately 9.4mm by 5.4mm spherical freezing zone of temperature between -20 to -100° C.

  • LidocaineDrug

    Also called xylocaine

    Roughly 3cc of lidocaine will be injected near the intermetatarsal neuroma under ultrasound visualization.

  • SalineDrug

    Roughly 3cc of saline will be injected near the intermetatarsal neuroma under ultrasound visualization.

Study groups in NCT02838758
Study groupRoleWhat they receive
CryoablationExperimentalUltrasound guided perineural cryoablation. The mechanism of therapeutic cryoablation involves using short and repeated cycles of freezing and thawing to cause axonal degeneration and disrupt neuronal activity without damage to epineurium and perineurium.
Receives: Device: Cryoablation
LidocaineActive comparatorUltrasound guided perineural lidocaine injection. Under ultrasound guidance, roughly 3cc of 2% lidocaine will be injected near the neuroma.
Receives: Drug: Lidocaine
SalinePlacebo comparatorUltrasound guided perineural normal saline injection. Under ultrasound guidance, roughly 3cc of normal saline will be injected near the neuroma.
Receives: Drug: Saline

What is being measured

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

  1. Numeric Pain Rating Scale

    Measured: up to 12 weeks

Secondary outcomes (1)
  1. Lower extremity functional scale (LEFS)

    A 20-item instrument current level of difficulty with each activity. All 20 items are scored with a maximum score 4 for each item. Scoring ranges from 0-80. The lower the score the higher the disability.

    Measured: up to 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Cryoablation, Lidocaine and Saline in people with Intermetatarsal Neuroma, run by Icahn School of Medicine at Mount Sinai 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 12 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: finished, as of the sponsor's last update on 6 Nov 2018. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Numeric Pain Rating Scale (time frame: up to 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02838758, which also lists 18 linked publications.

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 6 Nov 2018.
