NCT05855694

Brief Summary

This is a single site, pilot randomized, double blinded control trial designed to assess changes in cognitive symptoms in cancer survivors with cancer-related cognitive impairment. Patients will be randomized into one of two Arms: Intervention or Control.

  • Arm A: Intervention Group: Use of the THOR LED Photobiomodulation helmet 3x per week for 6 weeks. Helmet will be in 'therapeutic setting', 35mW/cm2 = 42J/cm2
  • Arm B: Control Group: Use of the THOR LED Photobiomodulation helmet 3x per week for 6 weeks. Helmet will be in 'placebo setting', 0mW/cm2 = 0J/cm2 This study has been designed to assess the hypothesis that Photobiomodulation can have a positive impact on cognitive symptoms in cancer survivors with cancer-related cognitive impairment. 30 participants will be recruited for this study, 15 per group. Self-report questionnaires assessing cognitive concerns, cognitive abilities, quality of life, depression, and anxiety will be administered at three timepoints through the study Baseline, End of Study Visit and 1 Month Follow Up

Outcome Measures

Primary Outcomes (1)

  • Cognitive Symptoms

    Cognitive symptoms will be measured by changes in scores on the PROMIS Cognitive Function-Short-Form 8a. Scores can range from 8-40. with higher score representing better outcomes.

    1-Month Follow Up

Secondary Outcomes (4)

  • Cognitive Abilities

    1-Month Follow Up

  • Quality of Life

    1-Month Follow Up

  • Depression

    1-Month Follow Up

  • Anxiety

    1-Month Follow Up

Study Arms (2)

Intervention Arm - Therapeutic Setting

EXPERIMENTAL

Photobiomodulation Helmet, Therapeutic setting, 35mW/cm2 = 42J/cm2, 3 x Sessions per week for 6 weeks

Device: THOR LED Photobiomodulation Helmet - Therapeutic

Control Arm - Non-Therapeutic Setting

SHAM COMPARATOR

Photobiomodulation Helmet, Non-Therapeutic setting, 0mW/cm cm2 = 0J/cm2, 3 x Sessions per week for 6 weeks

Device: THOR LED Photobiomodulation Helmet - Control

Interventions

Photobiomodulation (PBM) is a non-invasive treatment option that uses nonionizing light sources such as laser diodes and light-emitting diodes in the visible and near-infrared spectrum. Each participant will be required to sit with the helmet device over their head for the length of their study session. Participants and study staff will wear protective goggles throughout each session. These goggles help to block out any red LED light emitted from the helmet device. Participants may experience a pleasant warmth upon their head during both the therapeutic and control settings. Helmet will be in 'therapeutic setting' of 35mW/cm2 = 42J/cm2
