Local regulations and guidelines
Clinical trials in California are governed by U.S. Food and Drug Administration (FDA) regulations, Office for Human Research Protections (OHRP) standards, and federal HIPAA privacy rules. Every study is reviewed by an Institutional Review Board (IRB) to protect participant safety and ensure informed consent. In addition, California-specific protections such as the California Consumer Privacy Act (CCPA) and the Confidentiality of Medical Information Act (CMIA) impose stringent data-privacy requirements on research involving California residents.
Compensation & what to expect
- How payment typically works
- Compensation is most often provided through reloadable electronic study cards or direct deposit, paid out per completed visit rather than as a lump sum. Amounts vary by the time required, the number of visits, and the study's complexity — overnight stays and inpatient pharmacology studies generally pay more than short outpatient surveys. The exact amount is disclosed in writing during informed consent before any visit.
- Healthy volunteers
- Healthy participants aged 18 and older can earn compensation by joining vaccine, pharmacology, and biomarker studies in Pasadena. These trials check how a new drug or vaccine behaves in healthy bodies before later-phase testing. Many sites maintain a healthy-volunteer registry so you hear about new opportunities first.
- What's included beyond payment
- Most trials cover study-related medical care at no cost — physical exams, lab work, imaging, the investigational treatment itself, and follow-up visits with the research team. Insurance is not required to participate. Free check-ups and access to specialists are common reasons participants return for additional studies.
- Travel and time
- Many sponsors reimburse travel, parking, mileage, and lost wages for visit days. Long-running studies and trials that require frequent visits often raise stipends accordingly. Ask the study coordinator for the visit schedule and reimbursement policy before you commit.
- Asking about compensation
- Compensation is set per protocol and per site, so figures are not published in trial registries. The fastest way to confirm payment for a specific study is to contact the recruiting site listed on the study record. Coordinators are accustomed to this question and will quote the per-visit and total amounts up front.
