Request DemoHello, I am calling on behalf of the team at Hospital de Madrid. Am I speaking with Alberto T?
Yeah, that's me.
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?
Yeah, that's fine.
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?
Sounds perfect. Yeah.
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?
Uh, yeah, I am twenty-two.
Understood. Have you been diagnosed with Psoriatic Arthritis for at least three months?
Um, yeah, I have for two years now.
Thank you for confirming that. Do you have at least three swollen joints and three tender joints?
Asked from the protocol's inclusion criteriaUm, yeah, I have, uh, four actually. My two ankles and my two knees.
All right. Do you currently have cancer or have you had cancer within the last five years?
No, I haven't.
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?
Um, yes, I do actually on my left knee.
Understood. Is your Psoriatic Arthritis still active despite having used at least one conventional DMARD medication?
Um, yeah, actually it is. Yeah.
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?
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?
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.
