Brief summary

This is an open-label, interventional exploratory study to evaluate the safety and efficacy of 5-ALA-Phosphate + SFC in subjects with acute moderate or severe respiratory illness secondary to infection with SARS-CoV-2 virus (COVID-19) involving 40 subjects. The primary objective is to evaluate the safety of 4-week oral administration of 5-ALAPhosphate + SFC. This study is expected to last for 4 weeks and will include follow-up until day 28 in the hospital or in an outpatient setting if the subjects are discharged earlier.

Detailed description

This is an open-label, interventional exploratory study to evaluate the safety and efficacy of 5-ALA-Phosphate + SFC in subjects with acute moderate or severe respiratory illness secondary to infection with SARS-CoV-2 virus (COVID-19). Heme is critical for appropriate oxygen binding and delivery to remote site and without the heme contained within the hemoglobin tetramer, multicellular organisms would be unable to survive. Furthermore HO-1 degrades heme into biliverdin, carbon monoxide (CO), and iron, and biliverdin is immediately reduced and turned into bilirubin by biliverdin reductase. Biliverdin/bilirubin and CO both have anti-oxidative functions and they regulate important biological processes like inflammation, apoptosis, cell proliferation, fibrosis, and angiogenesis. Therefore, HO-1 is deemed to be a promising drug target (Ryter 2006). HO-1 is a major anti-inflammatory enzyme and a key regulator that induces immune tolerance. 5-ALA-Phosphate + SFC increases heme metabolism and HO-1 via enhancement of porphyrin biology and utilizes the HO-1 for endothelial pacification strategy. The primary endpoints of this study is- all treatment emergent AEs and SAEs Grade III and IV (CTC) with reasonable possibility of causal relationship to 5-ALA-Phosphate + SFC. 40 subjects with symptoms requiring hospitalization will be enrolled in thestudy, with 20 subjects enrolled in each group below: Group 1: 20 Moderately ill hospitalized subjects not requiring assisted ventilation Group 2: 20 Severely ill hospitalized subjects requiring assisted ventilation The duration of this clinical study will be 4 weeks, and follow-up will be performed until Day 28 in hospital, or in an outpatient setting if subjects improve and are discharged home or to alternative care facility.

Interventions

DIETARY_SUPPLEMENT5-ALA-Phosphate + SFC (5-ALA + SFC)

Moderately ill hospitalized patients will receive: 250 mg 5-ALA-Phosphate and 143.4 mg SFC (15.2 mg as Fe) two times daily (resulting in 500 mg 5-ALA-Phosphate and 286.8 mg SFC (30.4 mg as Fe) daily) for 7 days, then 250 mg 5-ALA-Phosphate and 143.4 mg SFC (15.2 mg as Fe) once daily for 21 days Severely ill hospitalized patients will receive: 250 mg 5-ALA-Phosphate and 143.4 mg SFC (15.2 mg as Fe) three times daily (resulting in 750 mg 5-ALA-Phosphate and 430.2 mg SFC (45.6 mg as Fe) daily) for 7 days, then 250 mg 5-ALA-Phosphate and 143.4 mg SFC (15.2 mg as Fe) once daily for 21 days

Inclusion criteria

1. Willing and able to provide written informed consent, or with a legal representative who can provide informed consent 2. Aged ≥ 21 to 70 years 3. Acute Respiratory Syndrome Coronavirus (SARS-CoV)-2 infection confirmed by polymerase chain reaction (PCR) test before beginning study dose regime 4. qSOFA ≥ 1 5. Currently hospitalized 6.
