Brief Summary

Flonoltinib Maleate as a JAK/FLT3 dual target inhibitor, previous pharmacological experiments showed that the IC50 inhibition of JAK2 kinase was as low as 0.8 nM, while the IC50 inhibition of JAK1, JAK3 and TYK2 kinases was 26 nM, 39 nM and 2 nM, respectively, and the IC50 of FLT3 kinase was 15 nM. It has high inhibitory activity for JAK2 kinase and good selectivity for JAK family.Multiple pharmacodynamic models evaluating the anti-inflammatory effect of Flonoltinib Maleate showed that Flonoltinib Maleate showed better therapeutic effect than the clinical drug Ruxolitinib with lower toxicity.

Study Groups

FM+SOC

Group Type: EXPERIMENTAL

SOC

Intervention Type: DRUG

In this study, the standard treatment plan (SOC) for COVID-19 in the Department of Respiratory and Critical Care Medicine was used as the best accessible treatment, and the treatment plan principle was based on the latest national guidance document ("Expert Recommendations for Clinical Treatment of Severe Novel Coronavirus Infection Caused by Omicron Variant"; "Diagnosis and Treatment Plan for Novel Coronavirus Infection (Trial Version 10)"; "Diagnosis and Treatment Plan for Severe Cases of Novel Coronavirus Infection (Trial Fourth Edition)"). In this study, the drug flunotinib maleate (FM) 100mg is a class of JAK inhibitors of anti-inflammatory therapy of SOC as standard clinical treatment regimen, and will be used in combination with SOC according to the judgment of the investigator.

Adults with any of the following are defined as critically ill with COVID-19: respiratory failure requiring mechanical ventilation; Appearance of shock; Other organ failure requires ICU monitoring; Severe and critical cases of novel coronavirus infection, collectively referred to as "severe cases". Severe cases can also be managed as severe cases if pneumonia caused by novel coronavirus infection does not meet the diagnostic criteria for severe cases: age > 65 years old, incomplete full vaccination, and more serious chronic diseases (including hypertension, diabetes, coronary heart disease, chronic lung disease, malignant tumors, and immunocompromise, etc.)

3. Patients with risk of progression before enrollment: at least one inflammatory index greater than the upper limit of normal (IL-6, CRP, d-dimer, LDH, ferritin≥ULN) within 2 days;

4. willing and/or able to comply with research-related procedures and assessments;

5. Those who can understand and agree to participate in this research and sign the informed consent form;

Exclusion Criteria

1. Known or suspected allergy to the test drug and its excipients;

2. Are receiving cytotoxic or biological therapy (such as TNF inhibitors, IL-1 inhibitors, IL-6 inhibitors (tocilizumab, adalimumab, etc.), T cell or B cell targeted therapy (rituximab, interferon, etc.), or Janus kinase (JAK) inhibitors, except for this study.

3. Have received convalescent new coronary pneumonia plasma or intravenous human immunoglobulin; have received clearly effective COVID-19 virus neutralizing antibodies;

4. In addition to the new crown infection, there are other serious infections, suspected serious bacteria, fungal viruses, active tuberculosis, NTM, etc.

5. Known positive for HIV antibody, positive test for active hepatitis B virus (HBsAg positive, HBV-DNA positive or ≥1000 copies/mL), anti-HCV antibody or HCV-RNA positive;

6. Have received a live vaccine within 1 week prior to screening, or are expected to be vaccinated during the study period.

7. Severe liver disease (total bilirubin (TBIL) ≥ 3 times the upper limit of normal value, alanine aminotransferase (ALT), aspartate aminotransferase (AST) ≥5 times the upper limit of normal value);

8. Those with severe renal insufficiency (glomerular filtration rate ≤ 30 mL/min/1.73 m2) or receiving continuous renal replacement therapy, hemodialysis, peritoneal dialysis;

9. Blood routine: neutrophil count < 1.0×109/L, lymphocyte count < 0.2×109/L, platelet < 30×109/L, hemoglobin < 60g/L;

10. Patients with malabsorption syndrome, or any other condition that affects gastrointestinal absorption, requiring intravenous nutrition or unable to take oral medications;

11. Invasive respiratory support or advanced life support, such as ECMO, is required.

Patients who have suffered from malignant tumors in the past 5 years and are currently uncontrolled; (13) Patients who participated in other new drugs or medical devices within 1 month before screening and took the investigational drug and used the investigational device; (14) Pregnant or lactating female patients, female patients with fertility and male patients who refuse to use contraception during the trial and within 6 months after the end of the test; (15) having taken a strong CYP3A inhibitor (such as ketoconazole, clarithromycin, itraconazole) or a strong CYP3A4 inducer (rifampicin) within two weeks before the first dose; (16) Patients with congenital coagulation abnormalities, such as patients with a history of multiple thrombosis and bleeding diseases; (17) Alcohol dependence or drug abuse; The researchers believe that patients with rapid disease progression are unlikely to survive for at least 48 hours after screening; or other factors that are not suitable for participation in the trial。
