I signed up for the biomarker study. It looks like they have options for drug trials for POTS, migraine, and MCAS, but not ME/CFS as far as I can tell.
I'm not sure. For the drug trials it says must be physically able to travel to Metrodora Institute. I sent an email and will let you know if they respond.
This might be the POTS trial: https://www.medifind.com/articles/clinical-trial/529149000 IgPro20 appears to be a kind of Immunoglobulin, with the alternative name Hizentra.
This might be the Dysport Migraine trial: https://www.medstarhealth.org/blog/dysport-migraine-studies Dysport is similar to Botox.
Ah, so I guess Metrodora is only one of many locations doing these drug trials. Lots of other countries for this one.
Yeah, it seems like all of the pharma run trials covers many locations. They probably need it to get enough participants.
