Can I join an asthma trial if my asthma is mild?

Some studies recruit mild asthma, but most current trials target moderate-to-severe or uncontrolled asthma because that is where new biologics are aimed. Screening includes lung function tests and a review of your symptom history to place you in the right study.

Will I get a placebo instead of real asthma treatment?

In most modern asthma trials, a placebo is added on top of your regular controller medication, not instead of it. You keep your rescue inhaler in every study. The consent form states the exact design, including your odds of receiving the investigational treatment.

How much time do asthma trial visits take?

Plan for 1-2 hours per visit, roughly monthly. Some studies front-load screening with a longer first visit that includes full lung function testing and blood work, which is also compensated.

Do asthma trials pay for travel?

Most sponsors reimburse mileage or rideshare costs on top of the visit stipend, and some offer additional caregiver or parking allowances. Ask the site coordinator what is included before your first visit.

Both new-diagnosis and long-term asthma patients are recruited, and compensation typically includes travel reimbursement plus per-visit stipends.

Asthma trials at a glance

Typical participant compensation: $500-$2,500 total ($75-$125 per visit)

Cost to you: $0, study care, testing, and treatment are provided free

Ranges reflect typical published study compensation; the exact amount for any study is listed in its consent form and varies by sponsor, location, and visit schedule.

What asthma studies are recruiting for

Asthma research is especially active in biologics, injectable antibodies that target the inflammation behind moderate-to-severe asthma. Sponsors need participants whose asthma is not fully controlled by standard inhalers.

Trials usually involve monthly clinic visits with breathing tests and questionnaires, plus a daily symptom diary. If your asthma flares often despite using your inhaler correctly, you are exactly who these studies are designed for.

DonorPayCalculator may earn a commission when you request study information through this link. Study participation decisions are made between you, your doctor, and the research team.

Who typically qualifies

Adults (some studies enroll adolescents with parental consent)
Physician-diagnosed asthma, often uncontrolled on current therapy
Willing to track symptoms and peak-flow readings between visits
Non-smokers or limited smoking history for many protocols

Every study defines its own criteria, and screening (which is free and usually compensated) is how you find out for sure. A “no” for one study is often a “yes” for another recruiting the same condition.

How joining works

Match: submit your interest and basic info for studies recruiting your condition near you.
Pre-screen: a short phone or online questionnaire checks the basics.
Screening visit: free medical evaluation (labs, measurements, history) to confirm eligibility, often paid even if you do not continue.
Informed consent: you get the full study details, including the exact compensation schedule, in writing before agreeing to anything.
Participate: attend visits, get compensated per visit, and withdraw at any time if you choose, you keep what you have earned.
