OPtimisation of Antiviral Therapy in Immunocompromised COVID-19 Patients

OPtimisation of Antiviral Therapy in Immunocompromised COVID-19 Patients: a Randomized Factorial Controlled Strategy Trial: the SWISS OPTICOV Study


Sponsor

Calmy Alexandra

Enrollment

256 participants

Start Date

Apr 27, 2023

Study Type

INTERVENTIONAL

Conditions

Summary

The overall purpose of the trial is to evaluate the efficacy and safety of possible combination antiviral therapy direct antiviral agents (remdesivir + nirmatrelvir/r) versus the reference monotherapy (nirmatrelvir/r alone) and to assess the efficacy and safety of increasing the nirmatrelvir/r course from 5- to 10 days in immunocompromised patients diagnosed with asymptomatic or mild to moderate Coronavirus Disease 2019 (COVID-19).


Eligibility

Min Age: 16 Years

Inclusion Criteria28

  • Laboratory confirmed SARS-CoV-2 infection by real time RT-PCR or positive antigenic test (commercialized assay)
  • Asymptomatic or mild to moderate COVID-19 (WHO progression scale \<5. Patients receiving oxygen therapy for reasons other than a pulmonary COVID-19 are eligible).
  • ≥ 16 years of age;
  • Immunocompromised as defined by ≥ 1 risk factors for severe COVID-19 as assessed by the Federal Office of Public Health (FOPH) list (criteria 5: diseases/treatments leading to immune suppression) or other immunosuppression criteria such as:
  • Severe immunosuppression (e.g., human immunodeficiency virus (HIV) infection with CD4 + T cell count \<350 / μl)
  • Neutropenia (\<1000 neutrophils / μl) ≥1 week
  • Lymphocytopenia (\<200 lymphocytes/μl)
  • On dialysis treatment
  • Hereditary immunodeficiencies
  • Intake of drugs which suppress the immune system (e.g. glucocorticoids for a long time \[an equivalent dose of prednisone \>20 mg/day \> 3 months\], monoclonal antibodies, cytostatics, biological products, everolimus, mTOR inhibitors etc.) in the last 12 months
  • Active cancer under cytostatics or targeted therapy known to be immunosuppressive (e.g., platinum salts, cyclophosphamide, anthracyclines, taxanes, 5-fluorouracil, gemcitabine, purine inhibitors, proteasome inhibitors) or associated with hematologic toxicity (neutropenia, lymphopenia), for example sunitinib, imatinib, regorafenib.
  • Aggressive lymphomas (all types)
  • Acute lymphatic leukemia
  • Acute myeloid leukemia
  • Acute promyelocytic leukemia
  • T prolymphocytic leukemia
  • Primary central nervous system lymphoma
  • Stem cell transplantation
  • Light chain amyloidosis
  • Chronic lymphoid leukemia
  • Multiple myeloma
  • Sickle cell disease
  • Bone marrow transplant
  • Organ transplant
  • Being on the waiting list for an organ transplant
  • Willing and able to comply with study requirements and restrictions as described in the informed consent form (ICF)
  • Enrolled in or a beneficiary of a Social Security program (State Medical Aid (AME) is not a Social Security program) or holders of health insurance.
  • Participant's or its legal representative's signature of the informed consent form

Exclusion Criteria10

  • SARS-CoV-2 PCR ≥30 CT at screening
  • Hypersensitivity to study drugs (active substance(s) or excipients)
  • Body weight \< 40 kg
  • AST (Aspartate transaminase) and/or alanine transaminase (ALT) \> 5 times the upper limit
  • Cirrhosis Child-Pugh score C
  • Is taking or is anticipated to require any prohibited therapies\*.
  • Participation in another interventional clinical study with an investigational compound or device, including COVID-19 therapeutics, where the study intervention is performed in the 28 days preceding the inclusion and the 10 days after the inclusion. Investigators of the different clinical studies should agree on participant's inclusion.
  • Presence of any condition for which, in the opinion of the investigator, participation would not be in participant's best interest or that could prevent, limit, or confound the protocol-specified assessments
  • Having received antiviral treatments against SARS-CoV-2 in the 14 days before the inclusion with exception of those having received one or two doses of nirmatrevir/r in the 24h preceding the inclusion in the study.
  • Pregnant or breastfeeding female

Interventions

DRUGPaxlovid 5 days

Nirmatrelvir/r 300mg/100 mg bid will be given for 5 days, orally. Nirmatrelvir/r is a combination of two molecules: nirmatrelvir which is a protease inhibitor (against 3CL) and ritonavir which has a booster role. Nirmatrelvir/r (marketed by Pfizer under the brand name Paxlovid®) is indicated for the treatment of COVID-19 in adults who do not require supplemental oxygen and who are at increased risk for progressing to severe COVID-19.

DRUGPaxlovid 10 days

Nirmatrelvir/r 300mg/100 mg bid will be given for 10 days, orally.
