Brief Summary

Primary Objective is to evaluate the safety and efficacy of OT-101+Artemisinin when used in combination with standard of care (SoC) in hospitalized COVID 19 subjects versus SoC+ Artemisinin+Placebo.

Detailed Description

This is a randomized, double blind, placebo controlled study to evaluate the efficacy, safety and tolerability of OT-101+Artemisinin when used in combination with SoC in hospitalized subjects with severe COVID 19. Written informed consent must be obtained from all subjects or their legally authorized representative (LAR) during screening (up to Day 3 prior to dosing) and prior to study related procedures being performed. Following completion of all screening assessments and meeting of eligibility criteria, subjects will be enrolled and randomized on Day 1 to either receive OT-101+Artemisinin or placebo+Artemisinin in a 2:1 ratio for 7 days in combination with SoC therapy per local SoC policies, followed to Day 28.

Subjects: includes subjects with severe COVID 19 (WHO COVID 19 Clinical Improvement Ordinal Scale 5 - non-invasive ventilation or high flow oxygen, or 6 - intubation and mechanical ventilation) at screening.

Subjects will undergo assessment during hospitalization or could discontinue their treatment with OT 101 or placebo during the 7 day infusion period or any time later during the study. All subjects will be closely monitored for adverse events (AEs) from signing the informed consent form (ICF) for at least 21 days after the final dose of study treatment (until Day 28). Standard of care treatment may continue as clinically indicated (after the 7 day dosing completion) as per local institutional guidelines. If subjects are discharged after Day 7 (after completing dosing), post discharge assessments can be done either at home (home health visit) or at the site. For subjects who are discharged before Day 28 or who withdraw from the study early will have follow up phone calls or will be followed up at site or a home visit to collect safety data until End of Study on Day 28. On days of laboratory assessments, discharged subjects may have a home visit.

Eligibility Criteria

Inclusion Criteria

1. Hospitalized adult male or non-pregnant, non-lactating female subjects (between 18 and 80 years), with SARS-CoV-2 (previously known as 2019-nCoV) infection that is documented by authorized diagnostic PCR test. A rapid PCR test could also be used. Confirmation that subject has COVID-19 within the last 2 weeks prior to randomization.

2. Meeting WHO COVID 19 Clinical Improvement Ordinal Scale Criteria 5 (non-invasive mechanical ventilation or high-flow oxygen) or Criteria 6 (intubation and mechanical ventilation).

3. O2 sat <= 93%

4. Male subjects and female subjects of childbearing potential must agree to use protocol specified methods of contraception.

5. Female subjects of childbearing potential and women of non childbearing potential (defined as at least 2 years postmenopausal or permanently sterilized women [bilateral tubal ligation, bilateral ovariectomy, or hysterectomy]) must have a negative serum pregnancy test at screening or pretreatment on Day 1.

6. The subject or a LAR has provided written informed consent.

7. The subject or the LAR is aware of the investigational nature of this study and willing to comply with protocol treatments, and other evaluations listed in the ICF.

Exclusion Criteria

1. Participation in any other clinical trial of an experimental treatment for COVID-19 or participation in another interventional clinical trial, including an expanded access trial.

2. Concurrent treatment with other agents with actual or possible direct acting antiviral activity against SARS CoV 2 infection <24 hours prior to study drug dosing except for remdesivir.

3. Uncontrolled hypertension (systolic blood pressure >150 mmHg and/or diastolic blood pressure >100 mmHg), unstable angina, congestive heart failure of any New York Respiratory Association classification, serious cardiac arrhythmia requiring treatment (exceptions: atrial fibrillation, paroxysmal supraventricular tachycardia), or history of myocardial infarction within 12 months of enrollment.

4. Hypotension requiring vasoactive peptides, such as dopamine, norepinephrine, epinephrine, or dobutamine.

5. Renal function impairment (creatinine clearance [Cr. Cl.] <50 mL/min, based on Modification of Diet in Renal Disease calculation).

6. Liver function impairment

1. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >5 × upper limit of normal (ULN), or ALT/AST >3 × ULN plus total bilirubin >2 × ULN.

2. Total bilirubin >1.5 × ULN, unless the subject has known Gilbert's syndrome.

7. Platelet count <50 000/µL

8. Multi-organ failure.

9. Document active infection with a bacterial pathogen requiring parenteral systemic antibiotics.

10. Bacterial or fungal sepsis.

11. History of live vaccination within the last 4 weeks prior to study enrollment; subjects must not receive live, attenuated influenza vaccine (eg, FluMist) within 4 weeks before enrolment or at any time during the study.

12. History of an allergic reaction or hypersensitivity to the study drug or any component of the study drug formulation.

13. Anti-inflammatory treatments other than steroids (eg, complement inhibitor, anti-GM-CSF antibody, anti-IL6 antibody) ARE PROHIBITED. However, antiviral drugs (eg, remdesivir,), systemic corticosteroids, and non steroidal anti inflammatory drugs (NSAIDs) ARE ALLOWED.

14. Presence of any uncontrolled concomitant illness, serious illness, medical conditions, or other medical history, including laboratory results, which, in the Investigator's opinion, would be likely to interfere with their participation in the study.

15. Major surgical procedure within 4 weeks prior to screening or anticipation of need for major surgical procedure during the course of the study.

16. History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to screening

17. History of organ allograft.
