Brief Summary:
To evaluate the safety and efficacy of intravenous administration of bone marrow derived extracellular vesicles, ExoFlo, versus placebo as treatment for moderate-to-severe Acute Respiratory Distress Syndrome (ARDS) in patients with severe COVID-19.

Condition or disease Intervention/treatment Phase
Covid19 ARDS Pneumonia, Viral Biological: DB-001 Phase 2

Detailed Description:
EXIT COVID-19 is a multi-center, randomized, double-blinded, placebo-controlled trial that will enroll 60 COVID-19 patients with moderate-to-severe ARDS at three research sites across the U.S. The primary efficacy endpoints will be all-cause mortality and median days to recovery.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Provision of signed and dated informed consent form (either by the individual or by the individual's healthcare proxy).
  2. Stated willingness to comply with all study procedures and availability for the duration of the study
  3. Male or female, aged 18-85.
  4. COVID-19 positive as defined by positive RT-PCR SARS-CoV-2.

Moderate to severe ARDS as defined by modified Berlin definition*, which includes timing within 1 week of known clinical insult or new or worsening respiratory symptoms; bilateral opacities not fully explained by effusions, or lung collapse; respiratory failure not fully explained by cardiac failure or fluid overload; PaO2/FiO2 ≤ 200 mm Hg.
  6. Clinical deterioration as evidenced by down-trending PaO2/FiO2 despite standard of care**.
  7. Acute presentation of hypoxia requiring noninvasive oxygen support such as NC, NRB, BIPAP, HFNC. OR Acute presentation of hypoxic respiratory failure which required intubation and subsequent mechanical ventilation.
  8. If the candidate is either male or females of reproductive potential, he or she must agree to use of double barrier method of highly effective birth control contraception such as condoms with oral contraceptive pill or choose to remain abstinent if already practicing abstinence during the screening period. The duration of required usage of double barrier method OR maintenance of abstinence must include the time from the beginning of the screening period until 90 days following the last dose of the study treatment.
