Brief Summary

This is a prospective, phase 3, multicenter, double-blind, randomized placebo-controlled study to investigate the efficacy, safety, and pharmacokinetics (PK) of repeat doses of IgPro20 in participants with post SARS-CoV-2 infection 2019 postural orthostatic tachycardia syndrome (post-Coronavirus Disease 2019 \[COVID-19\] POTS \[post-COVID-POTS\]).

Inclusion Criteria
  1. Provide written informed consent and be willing and, in the opinion of the investigator, able to adhere to all protocol requirements.
  2. Males and females aged ≥ 18 at the time of providing written informed consent.
  3. Diagnosis of post-COVID POTS, defined by both a preceding COVID-19 infection based on confirmed historical documentation and onset of POTS symptoms developing within 4 months after COVID-19 infection as defined per consensus criteria.
  4. COMPASS-31 score of at least 40 at the Screening visit.
  5. Positive confirmatory standardized standing test (ie, HR increase of ≥ 30 bpm [≥ 40 bpm for participants aged 18 to 19 years] within 10 minutes in the absence of orthostatic hypotension) at the Screening visit.

Exclusion Criteria
  1. Treatment with Immunoglobulin G (IgG) or plasmapheresis within 12 weeks before Screening
  2. Symptoms and / or diagnosis of or receiving treatment for POTS before COVID-19 infection
  3. Prior diagnosis of or receiving current treatment at Screening for the following conditions (unless onset was related to the inciting POTS-associated COVID-19 infection): certain neurologic, autoimmune, endocrine, cardiac, or other disorders, and pre-existing psychiatric disorders

Primary Outcome Measures
NameTimeMethod
Proportion of participants no longer meeting diagnostic criteria of post-COVID POTS as measured by standardized standing test (ie, no longer experiencing HR increase of ≥ 30 bpm, in the absence of 20 mmHg decrease of SBP [orthostatic hypotension])At screening, and at week 25
Secondary Outcome Measures
NameTimeMethod
Change from baseline in orthostatic intolerance score of COMPASS-31At baseline and at week 25

The Composite Autonomic Symptom Score 31 (COMPASS-31) is a self-reported questionnaire that measures autonomic symptoms related to 6 domains: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder and pupillomotor. The treatment effect of interest is differences from baseline in the orthostatic intolerance score of COMPASS-31.

Change from baseline in COMPASS-31 total scoreAt baseline and at week 25

The COMPASS-31 is a self-reported questionnaire that measures autonomic symptoms related to 6 domains: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder and pupillomotor. This questionnaire generates a weighted score from 0 to 100, with higher scores representing higher symptom burden.

Percentage of participants with TEAEs, related TEAEs, serious TEAEs and related serious TEAEsAfter treatment, for up to 57 weeks
Percentage of participants with ECG abnormalitiesAt baseline, at Week 25 and at Week 53
Number of participants with treatment-emergent adverse events (TEAEs), related TEAEs, serious TEAEs and related serious TEAEsAfter treatment, for up to 57 weeks
Number of participants with electrocardiogram (ECG) abnormalitiesAt baseline, at Week 25 and at Week 53
Change from baseline in heart rate increase within 10 minutes of standing testAt baseline and at Week 25
Change from baseline in ECG abnormalitiesAt baseline, at Week 25 and at Week 53
