Outcomes and clinical characteristics of the compassionate use of plitidepsin in COVID-19 patients with solid tumours, haematological malignancies or anti-CD20 antibody treatment.

Objective: To study the effect of plitidepsin antiviral treatment in immunocompromised COVID-19 patients with underlying haematological malignancies or solid tumours, particularly those who have undergone anti-CD20 therapies.

Design: We conducted a retrospective observational study, involving 54 adults treated with plitidepsin on compassionate use as an antiviral drug. Our analysis compared outcomes between patients with solid tumours and those with haematological malignancies, and a cohort of cases treated or not with anti-CD20 monoclonal antibodies.

Outcomes and clinical characteristics of the compassionate use of plitidepsin for immunocompromised adult patients with COVID-19.

Objectives: To evaluate the compassionate use of plitidepsin as an antiviral treatment in hospitalized immunocompromised adult patients with moderate-to-severe COVID-19.

Design: Retrospective observational study of data -collected from January 01, 2021 to April 30, 2022- from 35 immunocompromised adult patients with COVID-19 non-eligible for other available antiviral treatments. Main outcome measures were time to respiratory recovery (SpFi ≥ 315); COVID-19-related 30-day-cumulative mortality after first plitidepsin infusion; and time to undetectable levels of viral RNA.

Plitidepsin as a successful rescue treatment for prolonged viral SARS-CoV-2 replication in a patient with previous anti-CD20 monoclonal antibody-mediated B cell depletion and chronic lymphocytic leukemia.

Background: There is an urgent need for highly efficacious antiviral therapies in immunosuppressed hosts who develop coronavirus disease (COVID-19), with special concern for those affected by hematological malignancies.

Case Presentation: Here, we report the case of a 75-year-old male with chronic lymphocytic leukemia who was deficient in CD19CD20 B-lymphocyte populations due to previous treatment with anti-CD20 monoclonal antibodies. The patient presented with severe COVID-19 pneumonia due to prolonged severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and was treated with two courses of the antiviral plitidepsin on a compassionate use basis.

Clinical characteristics and outcomes among hospitalized adults with severe COVID-19 admitted to a tertiary medical center and receiving antiviral, antimalarials, glucocorticoids, or immunomodulation with tocilizumab or cyclosporine: A retrospective observational study (COQUIMA cohort).

Background: The COVID-19 outbreak challenges the Spanish health system since March 2020. Some available therapies (antimalarials, antivirals, biological agents) were grounded on clinical case observations or basic science data. The aim of this study is to describe the characteristics and impact of different therapies on clinical outcomes in a cohort of severe COVID-19 patients.
