Can herbs and viruses beat Drug-Resistant pneumonia?
NCT ID NCT07338123
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial tests a Chinese herbal formula (Yiqi Huoxue Jiedu) combined with bacteriophages—viruses that target specific bacteria—in 240 people with severe pneumonia caused by drug-resistant germs. The goal is to see if the combination clears the infection faster and lowers death rates. Because it's a very early study, results are uncertain and mainly check safety and basic effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Yiqi Huoxue Jiedu formula (herbal) and bacteriophages (viruses that kill bacteria)
- What this could lead to
- If it works, this could point toward a new treatment for severe pneumonia caused by drug-resistant bacteria, potentially reducing death rates.
- What could go wrong
- This is a very early (Phase 1) trial, so it may not show clear benefits. The combination of herbal medicine and phages is experimental, and risks are not yet well understood.

Inclusion Criteria: * Patients who meet the diagnostic criteria for severe pneumonia caused by drug-resistant Gram-negative bacilli and conform to the TCM syndrome differentiation of Qi deficiency, toxin accumulation and blood stasis syndrome; patients confirmed by rapid on-site microbiological evaluation (M-ROSE), clinical microbial culture and drug susceptibility testing (based on the drug susceptibility test results of our hospital or other Grade A tertiary hospitals) to be infected with multidrug-resistant Klebsiella pneumoniae, Acinetobacter baumannii or Pseudomonas aeruginosa; aged 18 to 85 years old; patients or their family members agree to cooperate with the collection of upper and lower respiratory tract specimens, consent to bronchoscopy plus bronchoalveolar lavage, and agree to receive nebulized inhalation of bacteriophage therapy; patients or their family members have fully read, understood and signed the informed consent form. Exclusion Criteria: * Women who are pregnant or lactating; patients with immunodeficiency; patients receiving immunosuppressive therapy or suffering from immunodeficiency diseases; patients who have received mechanical ventilation for more than 60 days prior to enrollment; patients with active pulmonary tuberculosis, lung abscess, or Grade D chronic obstructive pulmonary disease (COPD); patients with incomplete sampling or clinical data; patients with known allergies to bacteriophage products or the components of Yiqi Huoxue Jiedu Formula; patients judged by the researchers as unsuitable for participation in this study.
