All-cause mortality rate
28±2 days after randomization.
Peak concentration (Cmax)
72 hours before the first dose; 30 minutes before the first dose, at the end and 2, 4, 6, 8 hours after dose on day 4; 30 minutes before the second dose; 30 minutes before the first dose on day 10.
- +1 more secondary outcomes
Study Arms (2)
Colistimethate sodium for Injection + Meropenem
EXPERIMENTALIntravenous infusion of colistimethate sodium for injection for 7-14 days. Meropenem intravenous infusion once every 8 hours or 12 hours.
Coly-Mycin® M Parenteral + Meropenem
ACTIVE COMPARATORIntravenous infusion of Coly-Mycin® M Parenteral for 7-14 days. Meropenem intravenous infusion once every 8 hours or 12 hours.
Interventions
Colistimethate Sodium for Injection is the Prodrug of Polymyxin E, which is hydrolyzed into Polymyxin E after entering the human body to play a bactericidal role.Polymyxin selectively acts on gram-negative aerobic bacteria with hydrophobic outer membrane, leading to cell death by destroying the cell membrane.
Meropenem is a broad-spectrum carbapenem antibiotic that inhibits the synthesis of bacterial cell walls by penetrating the cell wall and reaching its target, the penicillin-binding protein, to ultimately produce antibacterial effects.
Coly Mycin M is the originally marketed colistimethate sodium for injection.
Eligibility Criteria
You may qualify if:
- Age ≥ 18 years old (based on the signing time of the informed consent form).
- The subject (or their guardian) voluntarily signs an informed consent form.
- Cultivate a Gram negative bacterium identified as carbapenem resistant within 5 days before or during the screening period (mainly including carbapenem resistant Enterobacteriaceae, carbapenem resistant Acinetobacter baumannii, and carbapenem resistant Pseudomonas aeruginosa), and the Gram negative bacteria showed drug resistance to carbapenems in vitro drug sensitive test. In this study, gram-negative bacteria resistant to carbapenems also included strains with bacterial drug sensitivity displayed as "intermediate", that is, resistant bacteria include strains that are intermediate and resistant to carbapenem antibiotics.
- Within 72 hours before randomization, for those who have previously received empirical antimicrobial treatment, the duration of antimicrobial treatment (excluding polymyxin antibiotics) does not exceed 24 hours or the treatment exceed 48 hours but the infection symptoms/signs still exist or become worsen.
- HAP/VAP subjects are required to meet:
- Patients with acute pulmonary parenchymal infection who have been hospitalized for more than 48 hours or discharged for less than 7 days, or have received mechanical ventilation through oral or nasal tracheal intubation for at least 48 hours;
- Chest X-ray examination (or computed tomography) obtained within 72 hours before randomization shows new infiltrating lesions or progression of existing lesions;
- Individuals with at least 2 of the following clinical symptoms/signs:
- New occurrence cough;
- Produce purulent sputum or tracheal secretions;
- The auscultation results are accord with pneumonia/lung consolidation (such as wet rale, dry rale, bronchial breath sound, egophony, dull percussion note);
- Difficulty in breathing, shortness of breath (respiratory rate\>25 breaths/minute), or hypoxemia (oxygen saturation\< 90% when breathing indoor air at standard atmospheric pressure or arterial blood oxygen partial pressure (PaO2) obtained through arterial blood gas (ABG)\<60 mmHg);
- The oxygenation index (arterial partial pressure of oxygen/percentage of inhaled oxygen concentration (PaO2/FiO2)) deteriorates, requiring urgent changes in ventilator support status or changes in positive end expiratory pressure ventilation volume.
- Within 72 hours before the first dose of study drug, the subject is required to take appropriate respiratory specimens (such as sputum, respiratory secretions, culture samples, etc.)
- With at least one of the following evidence of systemic inflammatory reactions:
- +29 more criteria
You may not qualify if:
- Individuals who currently have epilepsy/myasthenia gravis or have a history of seizures (excluding febrile seizures in childhood)/myasthenia gravis history.
- Individuals undergoing hemodialysis or peritoneal dialysis.
- Invasive aspergillosis, mucormycosis, or other invasive fungal diseases.
- Current patients complicated with other infections, including endocarditis, osteomyelitis, central nervous system infection (such as meningitis, brain abscess, infection after cerebrospinal fluid shunt or shunt device infection), artificial joint infection, and active tuberculosis.
- It is currently complicated with refractory septic shock, and there was still persistent hypotension after sufficient fluid resuscitation or pressure therapy before randomization.
- Evidence of obvious liver disease or dysfunction, including known acute viral hepatitis or hepatic encephalopathy.
- Individuals with immunodeficiency or low immune function, including but not limited to: human immunodeficiency virus infection, hematological malignancies, bone marrow transplantation, immunosuppressive therapy, systemic corticosteroid therapy (defined as a daily dose equivalent to prednisone ≥ 20 mg and a course of treatment\>14 days).
- Individuals with any laboratory test abnormalities during the screening period: aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) are 5 times higher than the upper limit of normal, or AST and/or ALT are 3 times higher than the upper limit of normal and total bilirubin is 1.5 times higher than the upper limit of normal, or neutrophil count is less than 1.0× 10\^9/L or platelet count\<60 ×10\^9/L; Creatinine clearance rate ≤ 50 ml/min.
- According to the clinical judgment of the researchers, the expected survival period is less than 1 month.
- Individuals with allergic reactions to polymyxin or carbapenems.
- Subjects who require more than 2 systemic antibiotics for the treatment of Gram negative bacterial infections.
- Patients with acute physiology and chronic health (APACHE II) scores greater than 30.
- HAP/VAP subjects need to exclude:
- Patients with lung diseases that can interfere with treatment response evaluation, (such as cystic fibrosis, granulomatous diseases, pulmonary fungal infections, or recent pulmonary embolism);
- Individuals with lung abscess, empyema, or obstructive pneumonia;
- +16 more criteria
