Painless Laser Therapy for Overactive Bladder (PLTOAB)

A Double-blind, Randomized, Sham-controlled, Multicenter Clinical Trial to Assess the Effectiveness of Therapeutic Class IV Laser LCT-1000TM Treatment for Overactive Bladder Syndrome.

The primary objective of this study is to determine the effectiveness of transvaginally-delivered low level laser therapy (LLLT) versus Sham in the treatment of overactive bladder symptoms in women. The secondary objective is to determine the effect of transvaginally-delivered LLLT vs. sham on the quality of life.

Study Overview

• Status: Unknown
• Conditions: Overactive Bladder
• Intervention / Treatment: Device: LCT-1000TM (Manufacturer: LiteCure); Device: LCT-1000TM (Manufacturer: LiteCure)

Detailed Description

This study is a double-blind, randomized, sham-controlled, multicenter, clinical trial that will include enrollment of up to 200 subjects at up to 3 investigational sites.

The study population will be randomized at a 1:1 ratio into two groups: Sham Laser Group (SLG) and Active Laser Group (ALG). The Sham Laser Group will receive a sham LLLT procedure (no laser energy) and the Active Laser Group will receive an active LLLT procedure (laser energy).

Both groups will undergo 3 LLLT procedures per week for 3 weeks, for a total of 9 LLLT procedures. Whether the procedure will be a sham procedure (placebo) or an active LLLT application will be determined by randomization which will assign subjects to be treated with an LCT-1000TM labeled either Laser A or Laser B. The only difference between Laser A and Laser B is that one does not emit laser energy; therefore, both subjects and site research personnel will be blinded as to whether laser energy is actually applied to the subject.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The primary efficacy endpoint will be the improvement of OAB symptoms and general quality of life due to the effect of LLLT treatment on OAB through week 7.	Patients will undergo 3 LLLT procedures per week for 3 weeks, for a total of 9 LLLT procedures.	Visits 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13 (over approximately 7 weeks)
The primary safety endpoint will evaluate the SLG and ALG treatment groups for differences in reported side effects and adeverse events throughout the trial, including LLLT treatment and follow-up.	Patients will undergo 3 LLLT procedures per week for 3 weeks, for a total of 9 LLLT procedures.	Visits 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13 (over approximately 8 weeks)
