BIO 300 Oral Suspension in Previously Hospitalized Long COVID Patients

Study Purpose

This is a randomized, double-blinded, placebo-controlled, two-arm study to evaluate the safety and efficacy of BIO 300 Oral Suspension (BIO 300) as a therapy to improve lung function in patients that were hospitalized for severe COVID-19-related illness and continue to experience post-acute respiratory complications associated with Long-COVID after discharge. Patients will be randomized 1:1 to receive BIO 300 or placebo.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Age ≥ 18. 2. Patients hospitalized for COVID-19-related complications ready to be discharged and those within 365 days of discharge (even if the patient was referred to subacute or acute respiratory rehabilitation after discharge) 3.

Acute onset (within 14 days of initial symptoms); and. 2.

Bilateral opacities not fully explained by effusions, lobar/lung collapse, or nodules; and. 4. Respiratory failure not fully explained by cardiac failure or fluid overload. 4. Radiographic signs of lung injury after standard treatment of COVID-19 such as, ground glass opacity, consolidation, or fibrotic shadows at screening. 5. Able to perform a PFT and have a DLCO <70% of predicted at screening. 6. Able to perform a 6-minute walk test. 7. Blood routine, liver and kidney function test values are within the controllable range. 1. Adequate hepatic function as evidenced by ALT, AST and LDH < 2X ULN and bilirubin < 1.5X ULN for the reference lab. 2. Adequate renal function as evidenced by a serum creatinine ≤ 1.5 X ULN for the reference laboratory OR a calculated creatinine clearance of ≥ 60 mL/min by the Cockcroft-Gault Equation. 3. Adequate hematopoietic function as evidenced by white blood cells ≥ 3x10^9 / L and platelets ≥ 100x10^9 / L. 8. Female patients of childbearing potential must have a negative pregnancy test at screening. 9. Female patients of childbearing potential and male participants with female sexual partners of childbearing potential must agree to use an effective method of non-estrogen-based contraception (e.g., condom and a diaphragm, condom and intrauterine device, condom and Depo-Provera, condom and Nexplanon, or condom and progesterone mini-pill) during the 12-week portion of the study that they are receiving study medication and for 30 days following the last dose of study medication, or to abstain from sexual intercourse during these time periods. Women who have been off estrogen contraceptives for a minimum of 5 days prior to the first scheduled day of study intervention dosing are eligible. A woman not of childbearing potential is one who has undergone bilateral oophorectomies or who is post-menopausal, defined as no menstrual periods for 12 consecutive months. 10. Ability of the patient or the patient's legal representative to read and provide written informed consent.

Exclusion Criteria:

1. Severe background disease like severe cardiac or pulmonary insufficiency (WHO grade III or IV), severe liver and kidney diseases, severe COPD, severe neurological disease, or concurrent malignancy (other than non-melanoma skin cancer) which is uncontrolled or actively being treated. 2. Severe asthma on chronic therapy with biologics or steroids. 3. Prior malignancy in which any thoracic radiotherapy was administered except for partial or tangent breast irradiation for early-stage (stages I or II) breast cancer. 4. D-dimer levels of >2,000 ng/mL at screening. 5. Use of anti-pulmonary fibrosis drugs (e.g., imatinib, nintedanib, pirfenidone, penicillamine, colchicine, tumor necrosis factor alpha blocker) within 5 days of the first scheduled day of study intervention dosing. 6. Use of anti-cytokine release syndrome drugs (e.g., anakinra, sarilumab, siltuximab, tocilizumab and/or lenzilumab) within 5 days of the first scheduled day of study intervention dosing. 7. Use of systemic corticosteroids (e.g., prednisone, dexamethasone) within 5 days of the first scheduled day of study intervention dosing. 8. An active infection or infection with a fever ≥ 38.5°C within 3 days of the first scheduled day of study intervention dosing. 9. Poorly controlled intercurrent illnesses, such as interstitial lung disease, uncontrolled hypertension; poorly controlled diabetes mellitus; unstable angina, myocardial infarction, acute coronary syndrome or cerebrovascular event within 6 months of Screening; history of congestive heart failure (NYHA Class III or IV); severe valvular heart disease; or poorly controlled cardiac arrhythmias not responding to medical therapy or a pacemaker. 10. QTc with Fridericia's correction that is unmeasurable, or ≥480 msec on screening ECG. The average QTc from the screening ECG (completed in triplicate) must be <480 msec for the patient to be eligible for the study. 11. Patients taking any concomitant medication that may cause QTc prolongation, induce Torsades de Pointes (www.crediblemeds.org) are not eligible if QTc ≥460 msec. 12. Patients who have undergone thoracotomy within 4 weeks of Day 1 of protocol therapy. 13. Patients that have a known allergy to any of the placebo components. 14. Psychiatric conditions, social situations or substance abuse that precludes the ability of the study participant to cooperate with the requirements of the trial and protocol therapy. 15. Pregnancy or currently on estrogen-based contraceptives. 16. Women who are breastfeeding. 17. Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
