Recruiting studies in California
- NCT07675135RecruitingPhase 3
Testing a new narcolepsy drug for excessive daytime sleepiness
This study tests a new medicine, HBS-301, for people with narcolepsy type 1 or type 2 who still have excessive daytime sleepiness. If you take other medications for sleepiness or mood, they must be stable for at least 3 months, and you cannot take some as-needed sleepiness medicines.
Lancaster, CaliforniaAges 18 years+ - NCT06531733Recruiting
Artemis Sleep Countermeasures Study
This NASA study tests methods to help astronauts sleep in space. Healthy volunteers aged 18–60 who don't have sleep disorders or certain chronic conditions can join to help improve sleep strategies during space missions.
Mountain View, CaliforniaAges 18–60 - NCT04984226RecruitingPhase 2
Sodium bicarbonate for kidney disease energy and acidity
This trial studies whether taking sodium bicarbonate changes “energy” in cells and improves metabolic acidosis (an acid build-up) in people with moderate-to-severe chronic kidney disease. You may be able to join if your kidney function and blood bicarbonate levels fit their targets and you meet safety rules.
Sacramento, CaliforniaAges 21–85 - NCT05367245RecruitingPhase 2
Butyrate supplement for Gulf War illness symptoms
This Phase 2 study tests whether a calcium–magnesium butyrate supplement can reduce symptoms of Gulf War Illness (GWI), especially by targeting gut and immune-related pathways. You may be eligible if you’re a Gulf War–era veteran with moderate-to-severe physical symptoms and no conditions or medicines that could explain them instead.
Long Beach, CaliforniaAges 40–70 - NCT05519878Recruiting
Light plus job therapy for fatigue in genitourinary cancer
This trial tests whether light therapy and an occupational therapy fatigue program can reduce fatigue in people with certain urinary-system cancers who still have mild fatigue during treatment. It may help you feel more energized and manage day-to-day activity while cancer treatment is ongoing.
Duarte, CaliforniaAges 18 years+ - NCT05741112Recruiting
Long COVID wearable study to track symptoms and help daily management
This study uses a wearable device to track symptoms and patterns in people with Long COVID, ME/CFS, and/or POTS. The goal is to see how wearable feedback and tracking tools may help you manage your symptoms.
La Jolla, CaliforniaAges 18 years+ - NCT05869682RecruitingPhase 2
Bright light therapy for fatigue and depression in prostate cancer
This Phase 2 study tests whether a “bright white light” intervention can reduce cancer-related fatigue and depression in people with advanced prostate cancer receiving hormone-based treatment. If it works, it could improve day-to-day well-being while you’re on standard cancer therapies.
Duarte, CaliforniaAges 60 years+ - NCT06989437RecruitingPhase 2/Phase 3
Study of Ponsegromab for Pancreatic Cancer with Weight Loss
This study tests an experimental drug called ponsegromab for people with advanced pancreatic cancer who experience severe weight loss and fatigue. It aims to see if the drug can help improve weight and energy levels while you continue standard chemotherapy.
Encinitas, CaliforniaAges 18 years+ - NCT06633224Recruiting
Fatigue and biology in cancer patients getting chemoradiation
This study looks at why some people feel very tired during cancer treatment. Researchers will collect blood and stool samples to study how the body responds to chemotherapy and radiation.
San Francisco, CaliforniaAges 18 years+ - NCT07227441Recruiting
Chronic Infections and Inflammation in ME/CFS
This study looks at how chronic infections and inflammation affect people with ME/CFS (myalgic encephalomyelitis/chronic fatigue syndrome) compared to healthy people. Researchers want to understand what causes symptoms and find better ways to help.
San Francisco, CaliforniaAges 18 years+ - NCT07581080Recruiting
Biofield therapy to ease fatigue from cancer immunotherapy
This study tests whether Reiki—a hands-on healing practice—can help reduce severe tiredness in cancer patients receiving immunotherapy drugs. If it works, it could offer patients another way to manage fatigue alongside their cancer treatment.
Irvine, CaliforniaAges 18 years+ - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.

What taking part in a fatigue study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

Common questions
- Are there fatigue clinical trials in California?
- Yes. We're currently tracking 12 recruiting fatigue studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a fatigue study in California?
- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
- Does it cost anything to join a fatigue trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New fatigue studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
