Phase 2a MIB-626 vs. Placebo COVID-19

The proposed phase 2a trial will determine whether MIB-626 treatment in adults with COVID-19 infection and stage 1 acute kidney injury is more efficacious than placebo in preventing worsening of kidney function, as assessed by longitudinal changes in serum creatinine concentration, and in attenuating the inflammatory response to the infection.

This is a two-center, randomized, double-blind, placebo-controlled, parallel-group, phase 2a study that will determine the efficacy and safety of MIB-626 treatment relative to placebo in adult patients with COVID-19 infection and stage 1 acute kidney injury.

Hospitalized adult patients with a confirmed or suspected diagnosis of COVID-19 infection will be screened for conformity to inclusion and exclusion criteria and those meeting eligibility criteria on screening will be offered participation in the study. Fifty participants, who meet all the eligibility criteria, and are able and willing to provide informed consent, will be randomized, stratified by sex, remdesivir use, and trial site, in a 3:2 ratio to receive either MIB-626 1.0 g orally or matching placebo twice daily for 14 days. The participants, who are discharged from the hospital before the completion of the 14-day intervention period, will be provided sufficient study medication to take home with them so they can continue to take the medication twice daily for the remaining duration of the 14-day intervention period.

Eligibility Criteria:
Inclusion Criteria:

* A man or a woman, 18 years or older
* Willing and able to provide informed consent, or with a legal representative who can provide informed consent with participant's assent
* Has Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV)-2 infection confirmed by an approved diagnostic test before randomization
* Currently hospitalized
* Documented increase in serum creatinine of 0.3 mg/dL or 50%-99% over baseline (baseline either based on admission serum creatinine or known pre-admission baseline, defined as most recent previous measurement)
* Participant or legal representative has read and signed the Informed Consent Form (ICF) after the nature of the study has been fully explained
* Is willing and able to provide authorization for the use and disclosure of personal health information in accordance with Health Insurance Portability and Accountability Act (HIPAA)
* Patients who are receiving remdesivir as a part of their clinical care or are in clinical trials of remdesivir or other antiviral drugs may be allowed if they meet other eligibility criteria
* Patients, who are participating in observational studies or studies of nonpharmacological interventions, will be allowed to participate
* Not be pregnant and not planning to become pregnant over the next 6 months

Exclusion Criteria:

* In the intensive care unit at the time of screening or prior to randomization
* Requiring mechanical ventilation at the time of screening or prior to randomization
* Has baseline estimated glomerular filtration rate \< 30 ml/min/1.73m2
* Has a history of kidney transplantation or hemodialysis treatment or receiving or expected to receive hemodialysis or peritoneal dialysis at screening and prior to randomization
* Is on mechanical ventilation
* Has a contraindication for MIB-626 or its inert ingredients
* Has a diagnosis of lupus nephritis, polycystic kidney disease, other glomerular disease (other than diabetes)
* Has AST or ALT \> 3 times the upper limit of normal
* Has other medical condition which, in the opinion of the Principal Investigator, would jeopardize the safety of the study subject or impact the validity of the study results
* Will exclude patients, who are receiving or are enrolled in placebo-controlled intervention trials of anti-inflammatory or immunomodulatory agents, such as tocilizumab. Occasional use of acetaminophen and nonsteroidal anti-inflammatory drugs, such as ibuprofen, for fever or headache is permitted.
