Recruiting studies in California
- NCT06948214RecruitingPhase 3
LUM-201 for growth hormone deficiency in children
This trial tests a new medicine called LUM-201 for children who haven't grown enough because their bodies don't make enough growth hormone. It aims to help kids who haven't been treated before and are still at an early stage of puberty.
Madera, CaliforniaAges 3–11 - NCT04867317RecruitingPhase 3
Growth hormone treatment for veterans with mild TBI and deficiency
This Phase 3 study tests whether replacing growth hormone in veterans with mild traumatic brain injury (mTBI) and low adult growth hormone can improve quality of life. If you qualify, you’ll be screened with hormone blood tests and memory/mental health checks before starting treatment.
San Diego, CaliforniaAges 21–55 - NCT05718570Enrolling by invitation
Long-term follow-up for adults taking Sogroya for growth hormone deficiency
This study follows adults with growth hormone deficiency who start (or have started) Sogroya to learn about its long-term safety. It does not change your treatment—it mainly checks for side effects and health outcomes over time.
Palo Alto, CaliforniaAges 18 years+ - NCT05775523Recruiting
Safety follow-up study for children using lonapegsomatropin
This study tracks the safety of lonapegsomatropin in children being treated for growth hormone deficiency (GHD). It’s meant to check for side effects and make sure the medicine continues to be safe in real-world use.
Sacramento, CaliforniaAges 1–18 - NCT05820672Recruiting
Study of people using Skytrofa in the United States
This study looks at how well and how safely Skytrofa (lonapegsomatropin) works for real-world patients in the U.S. It mainly gathers information from routine care to help doctors understand expected benefits and side effects.
San Francisco, CaliforniaAges Any age - NCT07221851RecruitingPhase 3
Weekly vs daily growth hormone for short stature in children
This trial tests a weekly growth hormone injection (lonapegsomatropin) compared to the standard daily growth hormone shot in children with short stature due to certain conditions. It aims to see if the weekly shot works as well or better and is safe.
Palo Alto, CaliforniaAges 2–17 - NCT06668805RecruitingPhase 2
Testing vosoritide for children with Noonan syndrome and slow growth
This study tests a medication called vosoritide for children with Noonan syndrome who are still growing slowly despite using human growth hormone. The goal is to see if vosoritide can help them grow taller.
Orange, CaliforniaAges 3–11 - NCT00903110Recruiting
Long-term safety registry for Increlex in children
This study is a registry that follows children and teens with severe IGF-1 deficiency who use Increlex (or specific GH gene deletion situations) to better track long-term safety and effectiveness. You would likely join if your child is already starting or planning Increlex and is not in other growth-related drug trials.
Orange, CaliforniaAges 2–18 - NCT06382155RecruitingPhase 2
Vosoritide for children with idiopathic short stature
This trial tests a medication called vosoritide to see if it can help children with unexplained short stature grow taller. It's for kids who are very short for their age but have normal growth hormone levels and no other known cause.

What taking part in a growth hormone deficiency 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.
