About this study

Official title: A Randomized, Prospective, Multicenter, Double-Blind, Sham-Controlled Study to Assess the MORPHEUSV Radiofrequency (RF) Device in the Treatment of Female Patients With Idiopathic Overactive Bladder (OAB) With Urge Incontinence and/or Urge-Predominant Mixed Incontinence

The goal of this clinical trial is to learn if a vaginal radiofrequency (RF) device called MORPHEUSV works to treat overactive bladder (OAB) in women. Researchers also want to learn how safe the device is for this indication. This study will include women ages 22 to 80 who have had OAB symptoms for at least 6 months. The main questions it aims to answer are: Does the MORPHEUSV device lower the number of daily episodes of accidental urine leakage caused by urgency? Does it work better than a sham (placebo) treatment? Researchers will compare the MORPHEUSV device to a sham treatment to see how well it reduces symptoms of overactive bladder. Participants will: 1) Receive one session of either the MORPHEUSV or sham treatment. 2) Track their symptoms using a diary and questionnaires 3) Return for three to six follow-up visits over 12 months. This study is being conducted at multiple clinics in the United States.

Read the detailed description

Overactive bladder (OAB) is a common condition that significantly impacts the quality of life in women, especially those with urge urinary incontinence (UUI) or mixed incontinence with a predominant urgency component. Current treatments for OAB, including behavioral therapy and pharmacologic agents, often have limited long-term efficacy, tolerability issues, or low adherence rates. There is a significant need for alternative, non-invasive therapies that can provide symptom relief with fewer side effects. The MORPHEUSV system is a vaginally delivered radiofrequency (RF) energy device designed to remodel submucosal tissue through controlled thermal stimulation. This technology is currently being investigated for its ability to improve bladder control by targeting pelvic tissue support and neuromodulation pathways. The device is investigational for this indication and is being studied under an FDA-approved Investigational Device Exemption (IDE G250071). This is a prospective, randomized, multicenter, double-blind, sham-controlled clinical trial designed to evaluate the safety and efficacy of the MORPHEUSV RF device in women aged 22 to 80 with idiopathic OAB and at least 7 episodes of UUI per week. The study will enroll approximately 202 participants at up to 12 sites across the United States. Participants will be randomized 2:1 to either a single session of active RF treatment or a sham (placebo) treatment. The primary outcome is the proportion of participants achieving a ≥50% reduction in UUI episodes from baseline at 6 months. Secondary and exploratory outcomes include symptom reduction across urgency, frequency, nocturia, and quality of life metrics, as well as device-related adverse events. Blinding will be maintained through the use of an identical sham applicator with no RF energy delivery. A crossover option is available for sham subjects who complete the 6-month follow-up, allowing them to receive the active treatment. All participants will be followed for 12 months after their initial intervention to evaluate durability of response and long-term safety. An internal data review committee will periodically evaluate cumulative safety data. The study is conducted under Good Clinical Practice (GCP) guidelines and will be overseen by Sterling IRB.

What participants receive

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

  • Detrusor nerve radiofrequency ablationDevice

    A single, vaginal radiofrequency (RF) treatment. The procedure is performed with a bipolar RF applicator and requires no anesthesia. Delivered in a single session in an outpatient setting.

  • Simulated (sham) detrusor nerve radiofrequency ablationDevice

    A simulated (sham) radiofrequency (RF) treatment, but with no energy delivered. The procedure mimics the appearance, duration, and positioning of the active device, without therapeutic effect.

Study groupRoleWhat they receive
MORPHEUSV Treatment ArmActive comparatorParticipants in this arm will receive a single session of radiofrequency (RF) treatment using the MORPHEUSV device. The treatment is delivered vaginally using a bipolar RF applicator at a therapeutic energy setting. No anesthesia is required. Participants will be followed for 12 months to evaluate safety and effectiveness.
Receives: Device: Detrusor nerve radiofrequency ablation
Sham Control ArmSham comparatorParticipants in this arm will undergo a procedure using a visually identical MORPHEUSV applicator, but without RF energy delivery (sham). The procedure mimics the appearance and duration of the active treatment. Participants will be followed for 12 months. After completing the 6-month follow-up, they may elect to cross over and receive a single session of the active RF treatment.

What is being measured

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

  1. Proportion of participants achieving ≥50% reduction in weekly urge urinary incontinence (UUI) episodes

    The percentage of participants who achieve at least a 50% reduction from baseline in the number of UUI episodes per week, as recorded in a 7-day bladder diary. This is the primary efficacy endpoint used to evaluate the effectiveness of the MORPHEUSV device compared to sham.

    Measured: 6 months post-treatment

Secondary outcomes (6)
  1. Change from baseline in mean number of UUI episodes per week

    Mean change in UUI episodes per week from baseline, based on 7-day bladder diary.

    Measured: 6 months

  2. Change from baseline in mean number of urgency episodes per week

    Mean change in urgency episodes per week from baseline, based on bladder diary.

    Measured: 6 months

  3. Change from baseline in mean number of micturitions per 24 hours

    Change in average number of daily voids as measured via bladder diary.

    Measured: 6 Months

  4. Change from baseline in Incontinence Quality of Life (I-QOL) total score

    Mean change from baseline in total score on the Incontinence Quality of Life Questionnaire (I-QOL), a validated 22-item patient-reported outcome measure assessing the impact of urinary incontinence on quality of life. Total scores range from 0 to 100, with higher scores indicating better quality of life.

    Measured: 6 Months

  5. Change from baseline in Urgency Perception Scale (UPS) score

    Mean change from baseline in urgency perception severity measured using the Urgency Perception Scale (UPS), a validated patient-reported scale assessing urinary urgency severity. UPS scores range from 0 to 3, with higher scores indicating greater urgency severity (worse symptoms).

    Measured: 6 Months

  6. Incidence and severity of adverse events

    Frequency and severity of treatment-emergent adverse events in each arm, collected at all follow-up visits.

    Measured: 12 Months

Model description
Participants will be randomized in a 2:1 ratio to receive either a single session of the MORPHEUS V radiofrequency (RF) treatment or a sham procedure. The study uses a parallel assignment model in which participants remain in their assigned group through the 6-month primary endpoint. After completing the 6-month visit, participants in the sham group may elect to cross over and receive the active treatment. All participants will be followed for 12 months from the time of their initial intervention to assess safety and durability of treatment effects.
