recover-autonomic platform protocol

Conditions: Long COVID; Long Covid19; Long Covid-19

Summary: this study is a platform protocol designed to be flexible so that it is suitable for a wide range of settings within health care systems and in community settings where it can be integrated into covid-19 programs and subsequent treatment plans. this protocol is a prospective, multi-center, multi-arm, randomized, controlled platform trial evaluating various interventions for use in the treatment of autonomic dysfunction symptoms, including cardiovascular complications and postural orthostatic tachycardia syndrome (pots), in pasc participants. the interventions tested will include non-pharmacologic care and pharmacologic therapies with study drugs.

the hypothesis is that some of the autonomic dysfunction symptoms are immune-mediated, so immunotherapy and other applicable therapies will result in improvement in autonomic symptoms. interventions will be added to the platform protocol as appendices. each appendix will leverage all elements of the platform protocol, with additional elements described in the individual appendix.
