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 PASC participants. The interventions tested will includenon-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.
Drug: IVIG + Coordinated Care
Participants will receive IVIG for a duration of 9 months and 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 a care coordinator.
Drug: IVIG Placebo + Coordinated Care
Normal saline given intravenously will be the control (placebo) product. Blinding IV bag
and tubing covers will be used for both IVIG and Placebo administration.
Participants will receive IVIG placebo for a duration of 9 months and coordinated
non-pharmacologic care for a duration of 3 months, concurrent with IVIG placebo
administration. Coordinated non-pharmacologic care involves volume expansion through high
salt diet, water intake, abdominal binder, exercise/rehabilitation, motivation,
education, and assisted care through a care coordinator.
Drug: Ivabradine + Coordinated Care
Participants will receive Ivabradine for a duration of 3 months and coordinated
non-pharmacologic care for a duration of 3 months, concurrent with ivabradine
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.
Drug: Ivabradine Placebo + Coordinated Care
The control (placebo) oral tablets will be similar to the study drug, ivabradine.
The control packaging matches the packaging.
Participants will receive Ivabradine placebo for a duration of 3 months and coordinated
non-pharmacologic care for a duration of 3 months, concurrent with ivabradine placebo
administration. Coordinated non-pharmacologic care involves volume expansion through high
salt diet, water intake, abdominal binder, exercise/rehabilitation, feedback, nutrition
counseling, motivation, education, and assisted care through care coordinator.
Drug: IVIG + Usual Care
Participants will receive IVIG for a duration of 9 months and usual non-pharmacologic
care (control) for a duration of 3 months. This will be concurrent with scheduled IVIG
administration.
Drug: IVIG Placebo + Usual Care
Normal saline given intravenously will be the control (placebo) product. The normal
saline will be of similar formulation and appearance to IVIG.
Participants will receive IVIG placebo for a duration of 9 months and usual
non-pharmacologic care (control) for a duration of 3 months. This will be concurrent with
scheduled IVIG placebo administration.
Drug: Ivabradine + Usual Care
Participants will receive Ivabradine for a duration of 3 months and usual
non-pharmacologic care (control) for a duration of 3 months, concurrent with ivabradine
administration.
Drug: Ivabradine Placebo + Usual Care
The control (placebo) oral tablets will be similar to the study drug, ivabradine.
The control packaging matches the packaging.
Participants will receive Ivabradine placebo for a duration of 3 months and usual
non-pharmacologic care (control) for a duration of 3 months, concurrent with ivabradine
placebo administration.
