Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Previous COVID-19 infection as documented by a positive Nucleic Acid Amplification Test (NAAT) PCR test or any licensed SARS-CoV-2 antigen test kit and prolonged, recurrent or newly developed symptoms more than 3 months after the positive test result.
  • Male or Female age ≥18 years
  • Provides written informed consent and is capable of reading and comprehending the informed consent
  • Able to swallow pills.
  • No active nausea, vomiting
  • All women of child-bearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to start of study medication. WOCBP is defined as any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), who is not postmenopausal (defined as amenorrhea for 12 consecutive months), or is on hormone replacement therapy (HRT) with documented plasma follicle-stimulating hormone level 35mLU/mL. Women who are using oral, implanted, or injectable contraceptive hormones or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy or practicing abstinence or where partner is sterile (e.g., vasectomy), should be considered to be of child bearing potential.
  • Female subjects who are not of reproductive potential (have reached menopause or undergone hysterectomy, bilateral oophorectomy or tubal ligation) or whose male partner has undergone successful vasectomy with resulting azoospermia or has azoospermia for any other reason, are eligible without requiring the use of contraception. Acceptable documentation of menopause, sterilization, and azoospermia is patient reported history.
  • All subjects must not participate in a conception process (e.g. active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization), and if participating in sexual activity that could lead to pregnancy, the female subject/male partner must use condoms (male or female) in addition to one of the following forms of contraception while on study: either a spermicidal agent, diaphragm, cervical cap, IUD, or hormonal-based contraception.

Who cannot join

  • Subjects unable to consent due to language barrier or cognitive impairment.
  • Pregnancy/lactation.
  • Regular use of agents that may affect inflammation in the last 3 months. The regular use of NSAIDS, aspirin, or statins will be allowed as long as dose has been stable for the last 3 months and is not expected to change during the study.
  • Subject receiving vitamin K antagonists (e.g. warfarin, coumadin)
  • Subject consuming supplements of vitamin K1, K2, or Vitamin D. A daily multivitamin will not be exclusionary as long as vitamin D is not > 600 UI daily.
  • Presence of active neoplastic diseases requiring chemotherapy and/or use of immunosuppressive drugs
Show all 10Show fewer
  • BMI <18 kg/m2.
  • Allergy or intolerance to vitamin K2 or vitamin D3
  • Hospitalization within the previous 28 days.
  • Inability or unwillingness of the individual to give written informed consent

About this study

Participants are being asked to take part in this research study because they have had a previous diagnosis (at least 3 months ago) of COVID-19 and are experiencing persistent, recurrent or even new symptoms, i.e. post-acute sequelae of SARS-CoV-2 (PASC). The Investigators are interested in studying the effects of Vitamin K2 (MK-7) and Vitamin D3 supplementation on PASC symptoms and the underlying inflammatory process.

Questions about this trial

What is this clinical trial studying?

A study testing Vitamin K2 (MK-7) and Vitamin D3 in people with Post-acute COVID-19 Syndrome, run by University Hospitals Cleveland Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in high-sensitivity C-reactive protein (hs-CRP) as measured by blood test (time frame: Baseline, week 12, week 24). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Sep 2024.
