Trial Outcomes & Findings for A Pilot Study Evaluating Photobiomodulation Therapy for Diabetic Macular Edema (NCT NCT03866473)
NCT ID: NCT03866473
Last Updated: 2022-09-19
Results Overview
Only eyes that completed the 4-month visit were included in calculation of descriptive statistics of optical coherence tomography (OCT) data. For eyes that received alternate DME treatment prior to 4 months (N=3 \[PBM\]; N = 1 \[placebo\]), the last OCT measurements prior to alternative diabetic macular edema (DME) treatment were used in place of the 4-month measurements. All analyses followed the intent-to-treat principle. Multiple imputation (m = 100) was used for missing values of central subfield thickness and retinal volume change, with imputation models that included variables for treatment group, baseline values, and change from baseline at all monthly interim visits up to the primary outcome visit and the randomization stratification factor of recent or planned intravitreous treatment in the non-study eye. Multiple imputation was not performed for center-involved DME given the thresholds are gender and machine specific. OCT CST change was truncated to the mean ± 3 SD (13 ± 3 × 5

Participant Flow
Visit completion at 4 months was prespecified as completion of any study visit from 12 to 24 weeks but due to the COVID19 pandemic, the window was extended to 32 weeks and participants in Phase 2 could also discontinue device use.

Photobiomodulation (PBM) Intervention
670nm wavelength device twice a day for 90 seconds through 4 months. At the 4-month visit, participants who have not already received alternative treatments for DME will return the original device and receive the alternative treatment group device (i.e. the sham group will receive an active treatment device and the active treatment group will receive a sham device).

Visual acuity is measured as a continuous integer letter score from 0 to 100, with higher numbers indicating better visual acuity. A letter score of 85 is approximately 20/20 and a letter score of 70 is approximately 20/40, the legal unrestricted driving limit in most states. A 5-letter change for an individual is approximately equal to a 1-line change on a vision chart. Visual acuity (VA) change truncated to mean ±3 SD (-0.3 ± 3 × 5.3). Eyes that received alternative treatment for DME before primary outcome visit (3 PBM, 1 placebo); last measurements taken before DME treatment was initiated were the pre-specified outcome data. Missing data for eyes that didn't get alternative treatment for DME imputed with multiple imputation.
