Treating Cancer-Related Fatigue Through Systematic Light Exposure (Light for Fatigue Study)

Study Overview
=================
Brief Summary
-----------------
Cancer related fatigue (CRF) is the most common cancer side effect and can severely interfere with activities of daily living long after completion of medical treatment. Pharmacologic agents to treat CRF have been studied but there is insufficient evidence to recommend their use. Non-pharmacological interventions for CRF have also been studied but are costly to implement and involve significant patient burden. This study investigates a novel low-cost/ low-burden intervention: systematic light exposure to treat CRF. Two hundred survivors of multiple myeloma and Diffuse Large B-cell Lymphoma between 1 month and 5 years post-autologous stem cell transplant (ASCT) will be recruited from three medical centers. The light will be administered by a small, personal light glasses daily for 4 weeks. Outcomes will be assessed at five separate time points, including baseline and follow-up. The study will specifically address recommendations made for interventions for CRF from the NCI Clinical Trials Planning meeting (JNCI, 2013).The proposed study will: 1) be the first large multisite study with a carefully delineated comparison condition to investigate the effects of light on CRF among ASCT survivors; 2) focus on a distinct, homogenous patient population; 3) include only survivors who experience clinical levels of CRF; and 4) address possible psychological and biological mechanisms. This study will have major public health relevance as it will determine if an easy-to-deliver, inexpensive, and low patient burden intervention effectively reduces CRF.

Detailed Description
-----------------
The proposed multi-site randomized controlled trial (RCT) will investigate a novel intervention, systematic light exposure (sLE), to treat cancer-related fatigue (CRF) among Multiple Myeloma (MM) and Diffuse Large B-Cell Lymphoma (DLBCL) following autologous stem cell transplantation (ASCT). Cancer related fatigue (CRF) is persistent exhaustion related to cancer and/or its treatment. CRF is the most common cancer side effect and can severely interfere with activities of daily living long after completion of all medical treatment. Pharmacologic agents to treat CRF have been studied but there is insufficient evidence to recommend their use. Non-pharmacological interventions for CRF (including yoga, cognitive behavior therapy, hypnosis, and exercise) have also been studied; however, such interventions are costly to implement and involve significant patient burden. sLE is a low-cost, low- burden intervention that we have found to have beneficial effects for patients post-ASCT. The investigators initial randomized trial for CRF found that certain light exposure was associated with clinically significant reductions in fatigue (effect size d=0.98) More relevant to the proposed research is the preliminary investigation with sLE to treat CRF in MM and DLBCL which found that patients receiving certain sLE reported significantly less fatigue ( p=0.052). The proposed RCT will test the efficacy of sLE on CRF. It will also assess the effect of sLE on sleep, depressive symptoms, and both activity and cortisol circadian rhythms as these related processes have been hypothesized as possible mechanisms of sLE's effects on CRF. Two hundred survivors of multiple myeloma and Diffuse Large B-cell Lymphoma between 1 month and 5 years post-autologous stem cell transplant (ASCT) will be recruited from two medical centers. The light will be administered by light glasses for 4 weeks. Outcomes will be assessed at five separate time points including baseline and follow-ups. The researchers' preliminary research has established the feasibility of this proposal. Moreover, in the preliminary research, 75% of participants completed the preliminary trial and data from the light box compliance meters showed that participants used the light boxes 80% of the days that treatment was scheduled. A large sample of fatigued MM and DLBCL ASCT survivors has been identified. The study will specifically address recommendations made for interventions for CRF from the NCI Clinical Trials Planning meeting (JNCI, 2013). It will: 1) be the first large multisite study with a carefully delineated comparison condition to investigate the effects of light on CRF among cancer survivors treated with ASCT; 2) focus on a distinct, homogenous patient population (MM and DLBCL ASCT survivors); 3) include only survivors who experience clinical levels of CRF; and 4) address possible mechanisms. This RCT will have major public health relevance as it will determine if an easy-to-deliver, inexpensive, and low patient burden intervention reduces CRF.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Potentially eligible ASCT survivors will be identified by HSCT physicians and nurses at each medical center. A research assistant (RA) will be introduced to survivors who express an interest in the research. An RA will explain the study and consent those who are eligible. Once informed consent is obtained, an RA will conduct the screening interview (including the FACIT-Fatigue scale and a psychiatric and sleep disorder screening). An RA will review a checklist of inclusion and exclusion criteria. This information will also be verified by a review of participants' medical charts before participation begins. Eligible study participants will be randomly assigned condition using a block randomization table prepared by our statistician. Participants who do not meet eligibility criteria or who decline participation will be informed that they have completed their participation.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Experimental Light<br>The experimental systematic light exposure consists of exposure to light to reduce cancer-related fatigue. This group will self-administer 30 minutes of light from commercially available light glasses (AYO) each morning for 4 weeks. The AYO light glasses is a lightweight pair of glasses that emits light from LEDs at a distance of 15 millimeters (15mm, 0.015m) from the eye. | Device: AYO light glasses (Experimental)<br>* The AYO does not contain UV or infra-red light; the light spectrum begins at approximately 420nm. The circadian-effective AYO is programed at over 100 lux with 470nm frequency and irradiance of 250 qW/cm2, which is 100% intensity level. Irradiance over lux itself with AYO light glasses is believed to be more representative due to light frequency and proximity to the eye. Traditional Lightbox usual measure is Lux , AYO can be seen as comparable to 1,000 lux light box. The device is classified as a device that is safe for the eyes in accordance with the international standard IEC 62471 and is independently certified by TÜV Rheinland. AYO complies with the EU's CE marking (CE EMC EN 55014, EN 61000-4-3) as well as other national regulatory directives. AYO also complies with the United States of America's FCC marking (FCC Title 47, Chapter 1, Part 15, Class B FCC VOC: 47 CFR PART 15 OCT, 2016. CLASS B ANSI C 63.4: 2014) as well as other national marking regulatory directives.<br>|
| Active Comparator: Comparison Light<br>The active comparator condition consists of exposure to light to reduce cancer-related fatigue. This group will self-administer 30 minutes of light from commercially available light glasses each morning for 4 weeks. | Device: AYO light glasses (Comparator)<br>* The comparison group will wear the same AYO glasses, but with a circadian ineffective (sham) light. The circadian-ineffective (sham) is programed at 1% intensity, therefore according to our calculation and checks it is below circadian threshold of 2 lux as specified.<br>|
