Description

Summary

The purpose of this study is to assess the safety and efficacy of leronlimab (PRO 140) administered as weekly subcutaneous injection in subjects with severe or critical COVID-19 disease.

Official Title

A Phase 2b/3, Randomized, Double Blind, Placebo Controlled, Adaptive Design Study to Evaluate the Efficacy and Safety of Leronlimab for Patients With Severe or Critical Coronavirus Disease 2019 (COVID-19)

Details

This is a Phase 2b/3, two-arm, randomized, double blind, placebo controlled, adaptive design multicenter study to evaluate the safety and efficacy of leronlimab (PRO 140) in patients with severe or critical symptoms of respiratory illness caused by coronavirus 2019 infection. Patients will be randomized to receive weekly doses of 700 mg leronlimab (PRO 140), or placebo. Leronlimab (PRO 140) and placebo will be administered via subcutaneous injection.

A single arm, non-randomized, open-label phase is added to the protocol after completion of enrollment in the Randomized Phase of the study.

The study will have three phases: Screening Period, Treatment Period, and Follow-Up Period.

    OR

    • Shock (defined by SBP < 90 mm Hg, or Diastolic BP < 60 mm Hg or requiring vasopressors)

  4. Subjects who have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to leronlimab (PRO 140) are not eligible.
  5. Inability to provide informed consent or to comply with test requirements
  6. Consideration by the investigator, for safety reasons, that the subject is an unsuitable candidate to receive study treatment
  7. Pregnancy or breast feeding
  8. Subject participating in another study with for an investigational treatment for COVID-19.

    Note: Subject who were prescribed (1) hydroxychloroquine or chloroquine with or without azithromycin, (2) Remdesivir, (3) convalescent plasma therapy, or (4) immunomodulatory treatments (including but not limited to sarilumab, clazakizumab, tocilizumab, and anakinra) for the off-label treatment of COVID-19 prior to study enrollment may be included and may continue to receive these agents as part of standard-of-care.
