Light Therapy for Osteoarthritis

Halifax, Nova Scotia
Managing joint pain is one of the main goals for treating osteoarthritis (OA) and other musculoskeletal disorders. Alleviating chronic pain pharmacologically has several potential drawbacks including diminishing efficacy, toxicity, adverse side-effects, and patient anxiety. Non-pharmacological approaches (eg. weight loss) have also been found to be effective at controlling joint pain and can provide supplementary benefits. The development of efficacious, alternative treatments for arthritis pain which provide analgesia without adverse side-effects would be advantageous. Recently, preclinical and clinical studies have demonstrated that green ambient light using light-emitting diodes (LEDs) produced profound analgesia in animal models and chronic pain patients. Both migraineurs and fibromyalgia patients have both reported significant reductions in pain following 10 weeks of green LED exposure. It is unknown how green light reduces pain, but it is believed to be in the connections between the visual and pain control centres in the brain. Investigators will examine whether green light reduces OA knee pain by altering pain processes in the brain. To assess this, we will recruit 44 participants and randomly assign them to one of two groups: one group will receive light treatments every day for 20 weeks and the other group will not. We will ask both groups to report pain in daily pain diaries and ask both groups to have a series of 3 MRI brain scans to determine if light exposure changes how the brain processes pain.

Intense Light Therapy for Critical Illness

Denver, Colorado
1. Elucidate the influence of intense light therapy pretreatment in patients undergoing cardiac surgery. We hypothesize that intense light exposure is associated with the peripheral stabilization of Per2 in human buccal swabs and plasma samples before surgery and with a decrease of Troponin I levels after surgery. In addition, we hypothesize that light therapy leads to Per2 dependent metabolic optimization in the human cardiac tissue. Therefore, a small piece of human heart tissue from the right atrium will be collected during cardiac cannulation, which will be otherwise discarded. 2. Critical illness (being in the intensive care unit) results in circadian malfunction and vessels not working. Vessel function is controlled by the body's circadian clock. Intense light boosts the circadian clock and the vessel function in animal studies. Vessels not working well in critical ill patients results in a myriad of severe diseases (delirium, stroke, heart attack, organ damage etc). Thus we will test if intense light can be used to boost the circadian clock and the associated vessel function in critical ill patients.

Time-Restricted Feeding for Circadian Rhythm Disorder

Fort Collins, Colorado
Insufficient sleep and circadian misalignment are independent risk factors for the development of obesity and diabetes, yet few strategies exist to counter metabolic impairments when these behaviors are unavoidable. This project will examine whether avoiding food intake during the biological night can mitigate the impact of circadian misalignment on metabolic homeostasis in adults during simulated night shift work. Findings from this study could identify a translatable strategy to minimize metabolic diseases in populations that include anyone working nonstandard hours such as police, paramedics, firefighters, military personnel, pilots, doctors and nurses, truck drivers, and individuals with sleep disorders.

Green and White LED Light Therapy for Chronic Pain

Tucson, Arizona
Chronic pain is a major problem in the USA and the rest of the world, currently, all available pharmacological interventions carry with them significant side effects. Pain clinics are specially equipped to perform intentional pain procedures to manage pain. However, there remain groups of patients what neither benefit from pharmacological nor from interventional pain procedures. Other methods have shown only minor benefits such as hypnosis or cognitive behavioral therapy. Therefore, other techniques need to be investigated. Light therapy has been shown to have significant biological effects on humans. For example, light therapy is used to manage depression. Several clinical trials have shown that certain wavelengths of light can improve wound healing, decrease temporomandibular joint dysfunction (TMJ) pain, and decrease fear of back pain. In these trials, light was directed at the site of pain. In an attempt to better understand the effect of different wavelengths of light, pre-clinical studies were conducted using rats. The investigators have shown green and blue Light emitting diode, (LED) light produced antinociception (analgesia) and reversed neuropathic pain associated with several models of chronic pain. The analgesic effect of light was completely blocked when rats had their eyes covered, this suggests that the analgesic effects seen are mainly due to systemic effect through the visual system. Preliminary experiments on rats suggest that this effect is mediated through the endogenous opioids and cannabinoid system. The investigators believe that LED light is a safe alternative to pharmacological intervention to manage pain by stimulating the endogenous endorphin and cannabinoid systems. The investigators initial target participants with history of HIV, chemotherapy induced peripheral neuropathy and fibromyalgia. Participants will be divided into 2 groups. The first group will be a control group exposed to white LED light. The second group will be exposed to green LED light, respectively. Participants will be asked to take LED light home and will be asked to set in a dark room for 2 hours daily for 3 months with their LED light on. At the end of the 3 months trial, the investigator will assess their pain intensity, analgesic use, and overall quality of life. The investigators hypothesis is that participants exposed to green and blue light will have less use of analgesics and will have better life quality.

Bright White Light Therapy for Prostate Cancer

Duarte, California
This phase II trial tests how well bright white light (BWL) therapy works in reducing cancer-related fatigue and depression in patients with prostate cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment with antiandrogen therapy (ADT) combination therapy. Combination treatment including ADT plus chemotherapy and androgen receptor (AR) targeted therapy or ADT plus AR targeted therapies work by reducing testosterone. Most prostate tumor cells rely on testosterone to help them grow; therefore, ADT combination therapy causes prostate tumor cells to die or to grow more slowly leading to improved overall survival in men with advanced prostate cancer when compared with ADT alone. However, lower levels of testosterone is also commonly associated with worsening fatigue and depression. If prolonged and severe, these complications can alter patient treatment plans, impacting not just quality of life, but leading to inadequate cancer control. BWL therapy is a type of phototherapy that utilizes bright white full-spectrum light, either through a light box or light therapy glasses to help regulate circadian rhythms. Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle, including the sleep-wake cycle which can become disrupted in cancer patients undergoing treatment, leading to increased fatigue. Additionally, exposure to bright light may increase the production of serotonin, a neurotransmitter that is associated with mood regulation. BWL therapy with AYOpro light therapy glasses may serve as a supportive care measure for men with advanced prostate to help reduce fatigue, as well as improve mood and overall quality of life during ADT combination therapy to maintain cancer care without suffering complications of therapy.

Light Therapy + Occupational Therapy for Genitourinary Cancers

Duarte, California
This clinical trial evaluates light therapy and occupational therapy in improving cancer related fatigue (CRF) patients with genitourinary cancers. Light therapy is a non-pharmacological and evidence-based intervention for managing fatigue in cancer patients. The use of light therapy can provide a low burden, inexpensive, and easy to disseminate intervention approach that can potentially have a larger impact on CRF. In addition, occupational therapy is a standard, but often underutilized, component of the multi-disciplinary approach to cancer care. Using the combination of light therapy and occupational therapy may be effective in CRF management.

Bright Light Therapy for PTSD

Portland, Oregon
The "polytrauma clinical triad" (PCT), a highly disabling constellation of factors, is defined by the coexistence of traumatic brain injury, post-traumatic stress disorder, and chronic pain. Veterans with the PCT are medically complex, often refractory to conventional therapies, and suffer from additional related chronic sequela. Notably, sleep disturbances and cognitive impairment, which the investigators hypothesize are significant contributing factors to these functional impairments and an impediment toward rehabilitation. Thus, the investigators' research aims to intervene "at the level of sleep", and by improving sleep, improve these interconnected, disabling, and difficult to treat enduring complexities associated with the PCT - ultimately to improve Veteran quality of life, functional independence, and restorative function. The investigators predict that the proposed intervention, morning bright light therapy, which is cost-effective, rapidly deployable and home-based, will be effective in improving sleep and overall PCT symptom management, thereby, resulting in a measurable and impactful improvement in quality of life.

Morning Bright Light Therapy for TBI

Portland, Oregon
One of the principal complicating factors associated with traumatic brain injury (TBI) is sleep-wake disturbances (e.g., insomnia, excessive daytime sleepiness, and circadian rhythm sleep disorders). Morning bright light therapy (MBLT) has been shown to improve sleep quality in a variety of conditions, but little has been done investigating the utility of MBLT in improving sleep in Veterans with TBI. This proposal aims to determine the effect of MBLT on sleep quality in Veterans with TBI. Veterans with and without TBI will be recruited from the VA Portland Health Care System. Baseline questionnaires and 7 days of actigraphy will be collected prior to engaging in 60 minutes of MBLT daily for 4 weeks, during which actigraphy will also be collected continuously. Post-MBLT questionnaire data will be collected, and follow-up questionnaire data will be collected at 3 months post-MBLT.

Light + Negative Ion Therapy for Depression

Vancouver, British Columbia
Antidepressants are widely used as first-line treatments for major depressive disorder (MDD). Clinical guidelines recommend 6-24 months of "maintenance" antidepressant treatment, after patients achieve symptom remission, to prevent relapse but many people stop antidepressants too soon relapse into another depressive episode. We will test non-medication treatments, negative ion therapy and light therapy, to see they can substitute for antidepressants to prevent relapse. This is a "feasibility" study to see if participants use study treatments properly, before doing a larger, definitive trial. In this 28-week study, 100 participants with MDD who are in remission with antidepressants will be treated with light therapy or negative ion therapy (with half of devices active and half inactive) while slowly discontinuing the antidepressant, and monitored for relapse.

Why Other Patients Applied

"I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Frequently Asked Questions

How much do clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest clinical trials?

Most recently, we added Light Therapy for Sleep Disorders and Cognitive Impairment, Light Therapy for Depression and Bright Light Therapy for IBS to the Power online platform.
