Brief Summary:

The purpose of the study is three-fold. The primary aim is to identify the proportion of Long-Haul COVID (LHC) and non-LHC volunteers with relevant symptoms actually have postural orthostatic tachycardia syndrome (POTS). The second is to determine benefit of ivabradine treatment. Ivabradine is a drug approved to treat tachycardia in persons with heart failure. The third is to characterize risk factors and outcomes among volunteers with and without LHC. This will include comparison with COVID-19-positive individuals who did not develop long-COVID symptoms.

The study will improve basic and applied knowledge of LHC and its associated cardiovascular and autonomic consequences. Cellular and molecular characterization of LHC and non-LHC participants will be performed with a nested clinical trial for Ivabradine responsiveness on reduction of tachycardia. It is hoped that a greater understanding of LHC, and related autonomic dysfunction in particular will help to identify treatment paradigms and therapeutic targets for improving recovery and enhancing health for those affected.


Condition or disease Intervention/treatment Phase
Long Haul COVID Postural Orthostatic Tachycardia Syndrome Drug: Ivabradine Phase 4

Detailed Description:

The study will first attempt to address the frequency of clinically confirmed POTS in those with persistent COVID-19 symptoms, particularly those symptoms suggestive of autonomic dysfunction.

Those with confirmed POTS or Inappropriate sinus tachycardia (IST) will be randomized to ivabradine or placebo to determine efficacy in reducing heart rate as a putative surrogate for POTS disease as well as effects on POTS symptoms. The biopsychosocial mechanisms of LHC and POTS will also be explored. Specific objectives will be:

  1. To assess the frequency and severity of fatigue, dyspnea, headache, and confusion and other suggestive symptoms among volunteers with and without LHC and measure the occurrence of clinically confirmed POTS or IST-in relation to these symptoms.
  2. To assess whether treatment with ivabradine will significantly reduce heart rate and improve symptoms and quality of life among subjects manifesting typical POTS or similar autonomic dysregulation.
  3. To characterize the immunoinflammatory and genomic factors associated with LHC and POTS among those with LHC. In particular, to determine whether those with POTS have differential expression of genes and/or proteins associated with autonomic nervous system function. To determine whether these factors reflect a genetic predisposition.
  4. To determine whether wearable automated ambulatory monitoring with existing FDA-approved devices will permit improved diagnostic accuracy for POTS.
  5. To determine the degree to which LHC induced autonomic instability and whether it is associated with induced inflammation and/or dysregulation
  6. To evaluate potential contribution of psychological symptoms and the interplay between psychosocial symptoms, quality of life, cognitive symptoms, and physiologic responses induced by LHC.
  7. To determine whether LHC improves following vaccination (in the limited number of cases where late vaccination occurs) and/or "breakthrough" clinical COVID-19 infection.
  8. Assess whether individuals with LHC have different antibody and/or cellular immune responses to SARS-CoV-2 antigens compared to infected individuals who did not develop LHC.
  9. Assess whether specific plasma protein markers of dysregulated blood coagulation, which were significantly correlated with immunothrombosis in severe COVID-19, persist in individuals with LHC.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 250 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Comparative Cohort Study of Post-acute COVID-19 Infection With a Nested, Randomized Controlled Trial of Ivabradine for Those With Postural Orthostatic Tachycardia Syndrome.
Actual Study Start Date : June 14, 2023
Estimated Primary Completion Date : September 1, 2024
Estimated Study Completion Date : September 1, 2024


Arm Intervention/treatment
No Intervention: Long Haul COVID
Persistent signs and/or symptoms >12 weeks post Covid-infection N = 200 evaluable subjects.
No Intervention: Post COVID without LHC
No persistent signs and/or symptoms >12 weeks N = 50 evaluable subjects.
Placebo Comparator: Ivabradine RCT Arms

If POTS or IST is present for participants within either of these cohorts, then they will be assigned to one of two arms of the Ivabradine RCT [2:1 treatment:control].

RCT Arms: at least 36 evaluable subjects will be enrolled to two arms in a 2:1 ratio. More may be enrolled, depending on the number from the overall COVID-19 cohort who qualify.

IVA (Ivabradine) - at least 24 evaluable subjects Placebo - at least 12 evaluable subjects

Drug: Ivabradine
Ivabradine is a drug approved to treat tachycardia in volunteers with heart failure. This study is to determine benefit of ivabradine treatment in postural orthostatic tachycardia syndrome (POTS) in participants with Long haul Covid.




Primary Outcome Measures :
  1. Change in standing heart rate following 3 months treatment. [ Time Frame: 3 months ]
    The primary endpoint will be a reduction in standing heart rate at 3 months. Up to 200 evaluable subjects will be enrolled in the general LHC cohort with the expectation that at least 20% of those recruited will have POTS or otherwise IST causing symptoms appropriate for enrollment to the nested RCT (ivabradine vs. placebo). This will yield an RCT study population of at least 40 evaluable subjects. Study recruiting will be aimed at volunteers with features of POTS. Drop-outs in all cohorts may be replaced.
