This study is a platform protocol designed to be flexible so that it is suitable for awide range of settings within health care systems and in community settings where it canbe integrated into COVID-19 programs and subsequent treatment plans.This protocol is a prospective, multi-center, multi-arm, randomized, controlled platformtrial evaluating various interventions for use in the treatment of autonomic dysfunctionsymptoms, including cardiovascular complications and postural orthostatic tachycardiasyndrome (POTS), in Post-Acute Sequelae of SARS-CoV-2 infection (PASC) participants. Theinterventions tested will include non-pharmacologic care and pharmacologic therapies withstudy 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.
Drug: IVIG (intravenous immunoglobulin)
Participants will receive IVIG for 9 months (36 weeks) with a follow-up period for an
additional 3 months (total study duration for 12 months).
Drug: IVIG Placebo
Normal saline given intravenously will be the control (placebo) product. Blinding IV bag
and tubing covers will be used for both IVIG and Placebo.
Participants will receive placebo for 9 months (36 weeks) with a follow-up period for an
additional 3 months (total study duration for 12 months).
Behavioral: Coordinated Care
Participants will receive coordinated non-pharmacologic care for a duration of 3 months,
concurrent with IVIG administration. Coordinated non-pharmacologic care involves volume
expansion through high salt diet, water intake, abdominal binder,
exercise/rehabilitation, motivation, education, and assisted care through care
coordinator.
Behavioral: Usual Care
Participants will receive usual non-pharmacologic care (control) for a duration of 3
months, concurrent with IVIG administration.
