A study that will check the safety, tolerability and effectiveness of the study drug (OMN6), as well as how the body responds to it after a single day of treatment, compared to patients who received a matching placebo.
EU CTIS ID: 2025-524200-29-00
What this study is testing
To evaluate the safety and tolerability and PK profile of single day dose-escalating OMN6 vs placebo in participants with HABP or VABP associated with ABC.
- Therapeutic exploratory (Phase II)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- 1. A signed informed consent form (ICF).
- 10. Background Antibiotic Therapy (BAT) including one or more of the following active BAT drugs: Meropenem, Ampicillin/Sulbactam and/or Colistin, is considered adequate empiric treatment for HABP/VABP based on local epidemiology.
- 2. Male or female participants 18 years or older at the time of signing informed consent.
- 3. Meeting the following clinical diagnosis criteria for HABP or VABP (refer to the protocol)
- 4. Participants with pneumonia Suspected or Confirmed to be associated with ABC Infection of the lungs (refer to the protocol)
- 5. Estimated glomerular filtration rate (eGFR) calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation: a. Sub-Cohort A (first sub-cohort at each dose level): eGFR >50 ml/min b. Sub-Cohort B (second sub-cohort at each dose level): eGFR 30–50 ml/min
You likely can't join if
- 1. Liver dysfunction - defined as the presence of one or more of the following laboratory abnormalities in baseline specimens: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, total bilirubin level >3 times the upper limit of normal (ULN), and/or platelet count <40,000/μL.
- 10. Immunosuppression resulting from the presence of an immunocompromising condition or receipt of treatment with immunosuppressant medication. Conditions and medications include: hematologic malignancy on active chemotherapy or biologics or treated by CAR-T cell therapy, bone marrow/stem cell transplant, receiving medication for rejection of transplantation and long-term use of systemic corticosteroids (systemic equivalent to ≥ 20 mg/day prednisone for ≥ 2 weeks).
- 11. Any condition or circumstance that, in the opinion of the Investigator, would compromise the participant’s safety or the quality of the study data.
- 12. Received another investigational drug or device within 30 days prior to study enrollment.
- 13. Known or confirmed active co-infection caused by other Gram-negative bacteria resistant to all BAT options is excluded.
- 14. The need for any additional or adjunctive non-study-specific antibiotic therapy (other than BAT) intended for the treatment of HABP or VABP.

- 6. Women of childbearing potential (WOCBP) (i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy) must have a negative serum pregnancy test within 72 hours prior to randomization.
- 7. Participating WOCBP must be willing to consistently use at least one highly effective method of contraception from Screening until EOS. Male participants, with female partners of childbearing potential, must be willing to use barrier methods of contraception and to refrain from donating sperm until EOS.
- 8. Acute Physiology and Chronic Health Evaluation II (APACHE II) score between 10 and 24 inclusive, or a Sequential Organ Failure Assessment (SOFA) score between 5 and 10 inclusive, at the time of diagnosis of infection. Participants not treated in an intensive care unit may be enrolled if they have a quick SOFA (qSOFA) score ≥ 2.
- 9. A chest X-ray or computed tomography (CT) assessed during Screening, or a previous chest radiograph or CT obtained within 96 hours prior to randomization showing the presence of new or progressive infiltrate(s) suggestive of bacterial pneumonia.
What rules you out
- 1. Liver dysfunction - defined as the presence of one or more of the following laboratory abnormalities in baseline specimens: aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, total bilirubin level >3 times the upper limit of normal (ULN), and/or platelet count <40,000/μL.
- 10. Immunosuppression resulting from the presence of an immunocompromising condition or receipt of treatment with immunosuppressant medication.

- 15. The need for any additional non-study specific therapy with drugs known to have significant interactions with BAT that could present a safety concern (e.g. valproic acid in participants receiving meropenem).
- 16. Concurrent infections in another site of the body that require either systemic, IV, or oral antibiotic therapy with activity against aerobic Gram-negative pathogens other than BAT.

- 3. Participants are excluded if they have received treatment with any BAT drug for more than 24 consecutive hours during the period from 14 days to 72 hours prior to the start of study treatment (Day 1). A single course lasting ≤24 hours during this period is permitted and does not result in exclusion.

History of any known hypersensitivity to Ampicillin/Sulbactam or Colistin or to carbapenems, or severe hypersensitivity to any other type of β-lactams other than cephalosporins and carbapenems (unless patient has previously received ampicillin-sulbactam or carbapenems without a significant adverse event).
