Recorded with Nacar's live screening agent

Agent

Hello, I am calling on behalf of the team at Hospital de Madrid. Am I speaking with Alberto T?

Candidate

Yeah, that's me.

Agent

Before continuing, I would like to inform you that I am an artificial intelligence agent and that I will record this call so that the team can review it. Do you agree?

Candidate

Yeah, that's fine.

Agent

Thank you. I am calling about the form you completed expressing interest in the Active Psoriatic Arthritis study. I will briefly tell you more about the study and ask you a few questions about your health, which the team will then review. Is that all right?

Candidate

Sounds perfect. Yeah.

Agent

We are conducting a research study to learn about the effectiveness and safety of different doses of a treatment in people with active psoriatic arthritis. If you participate, you will receive the study medication and attend regular check-ups to monitor your health. To start, are you eighteen years of age or older?

Candidate

Uh, yeah, I am twenty-two.

Agent

Understood. Have you been diagnosed with Psoriatic Arthritis for at least three months?

Candidate

Um, yeah, I have for two years now.

Agent

Thank you for confirming that. Do you have at least three swollen joints and three tender joints?

Asked from the protocol's inclusion criteria
Candidate

Um, yeah, I have, uh, four actually. My two ankles and my two knees.

Agent

All right. Do you currently have cancer or have you had cancer within the last five years?

Candidate

No, I haven't.

Agent

Thank you. Do you have active plaque psoriasis with at least one plaque that is two centimeters or larger, or nail changes related to psoriasis?

Candidate

Um, yes, I do actually on my left knee.

Agent

Understood. Is your Psoriatic Arthritis still active despite having used at least one conventional DMARD medication?

Candidate

Um, yeah, actually it is. Yeah.

Agent

Thank you. Have you taken apremilast at the approved dose for at least twelve weeks, or have you had to stop taking it due to intolerance?

Candidate

Yeah, I ha- I have been taking it for the two years I've had it. Yeah.

All right. If you are currently taking apremilast, have you been on a stable dose of thirty milligrams or less twice daily for at least twelve weeks?

Candidate

Um, yeah. Yeah, yeah. Uh, same dose as always, uh, 30 milligrams.

Thank you for that detail. If you are not currently taking apremilast, have you been off this medication for at least four weeks?

I am taking it, so it doesn't apply.

How Nacar

The site turns the protocol's criteria into the questions Nacar asks, in the exact wording you approve.

Bring in candidates

Nacar calls and screens

The agent interviews every candidate in their language, retries the ones who don't pick up, and files a structured report of every call.

You approve, Nacar books

Your team decides who qualifies. Nacar schedules the site visit and keeps reminders moving on WhatsApp.
