Outcome Measures

Primary Outcomes (1)

  • Change in COVID Disease Status

    COVID disease status was measured for improvement using the World Health Organization (WHO) ordinal scale for clinical improvement of COVID-19 over ICU admission within 27 days. The WHO scale is a 9-point ordinal scale ranging from uninfected (0), ambulatory (1-2), hospitalized with severe disease (5), hospitalized with intubation and organ support (6-7) and death (score of 8).

    Over 27 days from baseline, day 60 and day 90 day

Secondary Outcomes (11)

  • Renal Safety Biomarkers - Serum Oxalate

    On days 5,7 and 14

  • Renal Safety Biomarkers - Urine Oxalate Stones

    On days 5,7 and 14

  • Renal Safety Biomarkers - 24-hour Urine Oxalate Levels

    On days 5,7 and 14

  • Acute Kidney Injury-free Days

    Over 27 days from baseline

  • Number of Deaths

    Over 27 days from baseline, day 60 and day 90 day

  • +6 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults of 18 years or older
  • Patients hospitalized with a diagnosis of COVID-19 based on central laboratory-confirmed COVID-19 Novel Coronavirus Disease-2019, based on a positive SARS-CoV-2 RT-PCR confirmed within 72 hours prior to enrollment of nasal, oropharyngeal, or BAL specimen with hypoxemia, (i.e., decrease in oxygenation, as outlined below)
  • Pulse oximetry saturation (SpO2) \< 93% on room air in WHO COVID-19 ordinal scale 3 patients, regardless the need for assisted ventilation, or oxygenation.
  • Any new requirement of supplemental oxygen, with any oxygen device (WHO COVID-19 ordinal scale 4-7, regardless of pulse oximetry reading)
  • In patients with supplemental oxygen at home, any increase in the requirement of supplemental oxygen.
  • In ICU level care

You may not qualify if:

  • Age less than 18 years
  • Known allergy to Vitamin C
  • Inability to obtain consent from patient or next of kin
  • Presence of diabetic ketoacidosis
  • ANY history of oxalate stones at any time
  • Patients with Kidney Disease Improving Global Outcomes (KDIGO), CKD stage 4 (eGFR \< 30 ml/min, CKD stage 5 and end-stage renal disease on dialysis patients are excluded.
  • Patients with Acute Kidney Injury, stage 3.
  • Pregnant, or lactating
  • Known diagnosis of glucose-6-phosphate dehydrogenase (G6PD) deficiency
  • Patients who received the following medications within 7 days prior to enrollment, or plan to receive during enrollment, or 7 days after enrollment: aluminum hydroxide, bortezomib, copper, deferoxamine, amphetamines including derivatives such as fluphenazine.
  • Patients with active sickle cell crisis
  • Prisoners
  • Patients outside ICU level care
