Recruiting studies in California
- NCT06345339RecruitingPhase 2/Phase 3
Comparing Armour Thyroid to synthetic T4 for hypothyroidism
This study is testing whether Armour Thyroid (a natural pig-derived thyroid hormone) works as well as synthetic T4 (levothyroxine) for people with hypothyroidism. If you are already on a stable dose of levothyroxine, you may be able to switch to Armour Thyroid and see how it compares.
Burbank, CaliforniaAges 18–75 - NCT07747103RecruitingPhase 3
Porcine thyroid extract for hypothyroidism
This trial tests a new porcine (pig) thyroid hormone replacement tablet for people with primary hypothyroidism (underactive thyroid). It aims to see if this treatment is safe and effective compared to current levothyroxine therapy.
Modesto, CaliforniaAges 18–75 - NCT03977207Recruiting
Thyroid hormone supplement for people on dialysis
This trial tests whether taking a thyroid hormone supplement helps people who are on hemodialysis and have borderline-high thyroid lab results (high TSH but normal FT4). It’s studying whether treatment changes thyroid-related outcomes or health while on dialysis.
Orange, CaliforniaAges 18–75 - NCT06629272Recruiting
Reducing Unnecessary Thyroid Hormone in Older Adults

What taking part in a hypothyroidism 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 hypothyroidism clinical trials in California?
- Yes. We're currently tracking 5 recruiting hypothyroidism 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 hypothyroidism 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 hypothyroidism 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.
