Amira had spent the night reading about clinical trials.
Amira: Karim, look. This one is for my kind of cancer, and it's right here in the city!
Amira: I found this trial online. Can I join?
Dr. Nair: I'm glad you're looking. Let's go through its eligibility criteria together.
Karim: Eligibility criteria?
Read page 2 as text
Dr. Nair: Every trial has a list of who can join, and who can't. They're called inclusion and exclusion criteria.
Common eligibility criteria
- The type and stage of cancer
- Treatments you've already had
- Blood test results, such as kidney and liver function
- How active you are day to day
- Other health conditions
- Sometimes: a specific gene change in the tumor
Karim: Why so many rules?
Dr. Nair: They keep people safe, and they make sure the trial can answer its question clearly.

Dr. Nair: This trial is only for people who haven't had immunotherapy yet. You've already had it, so you wouldn't be eligible.
Amira: Oh.
It felt like a door closing.
Karim: Hey. We'll figure it out.
Dr. Nair: Not being eligible isn't about anything you did wrong. And this isn't the only trial out there.
Dr. Nair: Let me bring in Sam.

Sam: Your tumor testing found a specific gene change. There's another trial looking for exactly that.
Amira: So I'm in?
Sam: Not yet. First I need to ask how you're doing day to day.
Sam: Are you still working at the bakery all day? Or do you need to lie down and rest for half the day or more?
Amira: I'm up at five and on my feet until closing.
Karim: I try to make her sit down at lunch. She won't.

Sam: That's great to hear. This trial needs people who are up and about most of the day. Doctors call this your performance status.
Be honest about how much you can really do. It's easy to miss how much you've slowed down, so ask family what they've noticed.
Sam: Next, you'd sign a consent form for screening. Then blood tests and a scan, usually within a few weeks, to confirm you qualify.
Amira: And if I don't pass screening?
Sam: Then we keep looking together. It happens more often than people think, and it doesn't mean you're out of options.

Ways to find a trial
- Ask your oncologist or research nurse: they know which trials are open nearby.
- Search ClinicalTrials.gov, the official U.S. registry where clinical trials are listed.
- Call the National Cancer Institute's Cancer Information Service: 1-800-4-CANCER.
- Bring what you find to your care team. They can check the details with you.
Amira: One "no" just meant keep looking.
Every trial has eligibility criteria. They protect people and make results reliable.
Not qualifying for one trial doesn't rule you out of others. Screening tests confirm whether a trial is a fit.
