NCT04482673

Brief Summary

The purpose of this study is to evaluate how useful vitamin D supplementation is in reducing the severity of COVID-19 symptoms and the body's inflammatory and infection-fighting response to COVID-19. Individuals ≥50 years of age and older who are tested for COVID-19 and negative will be randomized (like flipping a coin) to either daily high dose vitamin D supplementation (6000 IU vitamin D3/day) vs. standard of care. Those individuals ≥50 years of age or older who test positive for COVID-19 at baseline will be randomized to bolus vitamin D (20,000 IU/day for 3 days) followed by high dose (6000 IU vitamin D/day) vs. standard of care for 12 months. All participants will receive a multivitamin containing vitamin D.

Outcome Measures

Primary Outcomes (3)

  • Change in total circulating 25(OH)D concentration

    metabolite of vitamin D

    monthly in COVID-19 negative participants through study completion for 1 year

  • Change in total circulating 25(OH)D concentration in COVID-19 positives

    metabolite of vitamin D

    baseline, 2 and 4 weeks, then months 3, 6, 9 and 12 in COVID-19 positive participants

  • Change in SARS-CoV-2 antibody titers

    The presence or absent of SARS-CoV-2 antibody will be measured at baseline, 3, 6, 9 and 12 months.

    every 3 months up to 12 months

Secondary Outcomes (10)

  • Change in inflammatory cytokine concentration (10 cytokine panel Elisa: Interferon (INF)-gamma, Interleukin (IL)-1beta, IL-2, IL-3, IL-4, IL-6, IL-8, IL-10, IL-13, Tumor Necrosis Factor (TNF)-alpha

    baseline and every 3 months up to 12 months

  • Respiratory symptoms

    daily for 2 weeks

  • Signs and symptoms of rhino/sinusitis

    Baseline then 3, 6, 9 and 12 months in negatives and daily for 2 weeks in positives

  • NCI Dietary Intake

    baseline then at 6 and 12 months

  • Charlson Comorbidity survey

    baseline then at 6 and 12 months

  • +5 more secondary outcomes

Study Arms (4)

COVID-19 Negative Active Treatment

EXPERIMENTAL

Participants will be randomized to vitamin D3 (6000 IU) per day for 12 months. All participants will receive a multivitamin containing 800 IU vitamin D3/day.

Drug: Daily Vitamin D3

COVID-19 Negative Placebo

PLACEBO COMPARATOR

Participants in this arm would receive placebo for 12 months. All participants will receive a multivitamin containing 800 IU vitamin D3/day.

Drug: Daily placebo

COVID-19 Positive Active Treatment

EXPERIMENTAL

Participants will be randomized to vitamin D3 as a bolus (20,000 IU) per day for 3 days followed by high dose vitamin D (6000 IU) per dayfor 12 months. All participants will receive a multivitamin containing 800 IU vitamin D3/day.

Drug: Daily Vitamin D3Drug: Bolus vitamin D3

COVID-19 Positive Placebo

PLACEBO COMPARATOR

Participants in this arm would receive placebo as a bolus followed by daily placebo for 12 months. All participants will receive a multivitamin containing 800 IU vitamin D3/day.

Drug: Daily placeboDrug: Bolus placebo

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may not qualify if:

  • Hospitalization at the time of study recruitment.
  • Any individual less than 50 years of age. The reason that the participants ≥50 years are being excluded from this study is because those who are ≥50 years have a higher risk of being symptomatic with COVID-19 and have the potential for the greatest benefit. The disease appears to manifest differently in children and its occurrence is quite rare.
  • Only those patients tested for COVID-19 initially will be eligible to participate; therefore, anyone wanting to participate in the trial must have had a COVID-19 test prior to enrollment/participation in the study.
  • Any individual who is not capable of making independent decisions and who is considered cognitively impaired.
