Clinical Trial Summary

The PRECISION is a proof-of-concept, phase II randomized clinical trial aiming to evaluate the efficacy and safety of anakinra in patients with Post-Acute COVID Syndrome (PACS) of the pro-inflammatory respiratory phenotype. Improvement is measured by a composite endpoint, namely, the "Score of PACS progression reversal"

Description:

People with COVID-19 might have sustained post-infection sequelae, known as Post-Acute Covid Syndrome (PACS). A recent consensus definition by an international panel of 265 patients, clinicians, researchers, and WHO staff suggests that post-COVID-19 condition occurs in individuals with a history of probable or confirmed SARS-CoV-2 infection, usually 3 months from the onset, with symptoms that last for at least 2 months and cannot be explained by an alternative diagnosis. Common symptoms include fatigue, shortness of breath, and cognitive dysfunction and generally have an impact on everyday functioning.

The role of immune dysregulation in PACS is indirectly supported from the findings of the SAVE-MORE randomized clinical trial, in which patients with moderate and severe COVID-19, were 1:2 randomized to treatment with placebo or anakinra once daily for 10 days. The primary endpoint was the distribution of the frequencies of patients in the 11 points of the WHO clinical progression scale (CPS) by day 28. Patients' follow-up until day 90 showed significant reduction of the incidence of PACS; this was 24.4% among placebo-treated patients and 15.7% among patients treated with anakinra.

After the end of the SAVE-MORE trial, the understanding of the immune activation of PACS and the development of tools for the evaluation of patients have become the main aims of the Hellenic Institute for the study of sepsis (HISS) group. More precisely, patients with medical history of COVID-19 pneumonia during three separate time periods and matched comparators for age, sex, comorbidities, and state of vaccination were followed up and evaluated for PACS. Main findings can be summarized as follows:

1. For at least one year after acute COVID-19 there is considerable immune dysregulation involving both the innate and the adaptive responses.

2. Patients with PACS may be classified into four main phenotype clusters: fatigue involving 70.8%, respiratory cluster involving 33.2%, systemic symptoms involving 17.7% and other symptoms involving 26.1%.

3. The risk for progression into PACS was significantly lower among patients treated with anakinra in the acute stage (odds ratio 0.59, p: 0.017) showing a role of IL-1 for the progression into PACS.

4. Patients with fatigue bring distinct immunotype compared to the respiratory cluster.

5. IP-10 (interferon-gamma-induced protein-10) at levels more than 250 pg/ml has sensitivity 99.3%, specificity 90.9%, positive predictive value (PPV) 97.9% and negative predictive value (NPV) 97.6% for the diagnosis of the post acute COVID immune dysregulation.

PRECISION is a proof-of-concept, randomized clinical trial (RCT) aiming to evaluate the efficacy and safety of anakinra in patients with PACS in improving the clinical and immunological state over 4 to 8 weeks as measured by a composite endpoint, namely, the "Score of PACS progression reversal".

10. Known active tuberculosis (under treatment) or latent tuberculosis (by positive tuberculin test)

11. Oral or IV intake of corticosteroids at a daily dose equal or greater than 0.4 mg/kg prednisone for a period greater than the last 15 days.

12. Any anti-cytokine biological treatment the last one month

13. Severe hepatic failure defined as Child-Pugh stage of 3

14. End-stage renal failure necessitating hemofiltration or peritoneal hemodialysis

15. Pregnancy or lactation. Women of child-bearing potential will be screened by a urine pregnancy test before inclusion in the study
