  • Subject is willing and able to comply with study instructions and commit to all follow-up visits for the duration of the study.
  • Subject is in good general health and free of any systemic disease state or physical condition that might impair evaluation or which in the investigator's opinion, exposes the subject to an unacceptable risk by study participation.

Who cannot join

  • A partial or full knee replacement (in the treated knee).
  • Any use of systemic injections (in any area) within the last 6 months.
  • Current enrollment in an investigational drug or a device study that specifically targets pain treatment.
  • Any additional diagnosis that in the opinion of the investigator may directly contribute to knee pain.
  • Any concomitant inflammatory disease or other condition that affects the joints (e.g. rheumatoid arthritis, metabolic bones disease, gout, active infection, etc.).
  • Any clotting disorder and/or has used an anticoagulant (e.g., warfarin, clopidogrel, etc.) within seven (7) days prior to administration of the device.

  • Any local skin condition at the treatment site that in the investigator's opinion would adversely affect treatment or outcomes.
  • Any chronic medical condition that in the investigator's opinion would prevent adequate participation.
  • Any chronic medication use (prescription, over-the-counter, etc.) that in the investigator's opinion would affect study participation or subject safety.
  • For any reason, in the opinion of the investigator, the subject may not be a suitable candidate for study participation (i.e., history of noncompliance, drug dependency, any related knee injury due to a worker's compensation claim, etc.).

About this study

Official title: A Prospective Non-Randomized Unblinded Study Evaluating the Treatment of Knee Osteoarthritis With the Cryo-Touch III Device

A proof of concept study to evaluate the feasibility of safe and effective treatment through optimization of the Cryo-Touch III device for temporary relief of pain.

Read the detailed description

Over 100 million patients in the United States suffer from chronic pain. Chronic pain conditions are often debilitating, taking a toll on a patient's physical and mental welfare. Though a variety of pain management techniques currently exist, the most common nonsurgical options provide slow-acting and/or short-term relief. Medication, often in the form of non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, comes with an array of side effects such as nausea and vomiting. Medication also presents the possibility of more serious effects such as increased risk of heart attack and stroke, and tolerance or dependency issues. Surgical strategies tend to be reserved for more severe cases and are limited by the risks and complications typically associated with surgery including bleeding, bruising, scarring, and infection. A nonsurgical, minimally invasive, long-lasting approach to chronic pain management is desirable.

The Cryo-Touch III is a pain management device developed for a novel, minimally invasive procedure using focused cold therapy to target sensory nerve tissue and offer long-lasting pain relief through cryoanalgesia. The device operates on the well-established cryobiology principle that localized exposure to controlled moderately low temperature conditions can alter tissue function. The therapy treats nerves with low temperatures via a cold probe in the form of an assembly of small diameter needles, creating a highly localized treatment zone around the probe. This focused cold therapy creates a conduction block that prevents nerve signaling.

Though studies have proven efficacious in targeting motor nerves, the device's effect on sensory nerves has yet to have been investigated in the clinical setting. The goal of the study described herein is to evaluate the degree and duration of effect of the Cryo-Touch III in reducing chronic pain by targeting sensory nerves.

What is being measured

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

  1. Average Improvement in VAS Pain Score From Baseline to Day 7

    Visual Analog Scale(VAS), where a higher score indicates greater intensity; 0= no pain, 10=worst pain

    Measured: Baseline to Day 7

  2. Improvement in WOMAC Index From Baseline to Day 7

    The Western Ontario and McMaster Universities Osteoarthritis (WOMAC) pain scale.

    A tri-dimensional, disease-specific, patient-reported outcome measure. Consists of 24 questions: 5 pain, 2 stiffness and 17 function. Each category contains a set of questions rated by the Subject on a 0-10 scale;

    The highest possible score was 50 for pain, 20 for stiffness and 170 for function, based on the 0-10 scale used to assess each question.

    The total score range is 0 to 240 with higher scores correlating to worse outcomes.

    Measured: Baseline to Day 7

Secondary outcomes (1)
  1. Number of Participants Who Experienced Continued Treatment Effect at Each Time Point

    Subjects were asked to report whether they experienced continued treatment effect at the timepoints indicated.

    Measured: Visit 3 (Day 7), Visit 4 (Day 30), Visit 5 (Day 56)

Questions about this trial

What is this clinical trial studying?

A study testing Cryo-Touch III in people with Osteoarthritis of the Knee, run by Pacira Pharmaceuticals, Inc at 2 sites 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 7 inclusion and 11 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 24 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. 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 29 Sep 2023). 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?

Average Improvement in VAS Pain Score From Baseline to Day 7 (time frame: Baseline to Day 7). The study lists 2 primary outcomes in all. 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 24 Jan 2024.
