ClinConnect Summary

This clinical trial is studying how two medications, ANT3310 and meropenem (often used to treat infections), behave in the lungs of healthy adults. Researchers want to understand how these medications are absorbed and distributed in the body when given through an intravenous (IV) infusion. Participants will undergo a procedure called bronchoalveolar lavage (BAL), which involves using a thin, flexible tube to collect fluid from their lungs, allowing the researchers to compare how the medications work in the bloodstream versus in the lungs.

To be eligible for the study, participants need to be healthy adults aged 18 to 55, with a normal body weight and no significant medical conditions. They should be able to provide informed consent, meaning they understand the study and agree to participate. During the trial, participants can expect to have medical assessments, including blood tests and monitoring their vital signs. This study is not currently recruiting participants, but it's important for potential volunteers to be aware of the strict health criteria to ensure safety during the trial.

Eligibility criteria

• Inclusion Criteria:
• • Capable of giving signed informed consent in compliance with the requirements and restrictions listed in the ICF and in the protocol.
• • Participants must be 18 to 55 years of age, both inclusive, at the time of signing the informed consent.
• • Body mass index (BMI) within the range 18.0-32.0 kg/m2 (both inclusive) and body weight \> 50.0 kg (110 Ibs) at Screening.
• • Contraceptive use by women or men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
• • Healthy participants as defined by absence of evidence of any active or chronic disease following a detailed medical and surgical history, 12-lead ECG, vital signs, physical examination, spirometry at Screening (FEV1 \> 80% of predicted), and clinical laboratory tests at Screening and Day -1.
• • Healthy participants with vital signs at Screening and Day -1 within the normal ranges: tympanic body temperature: ≥ 35.5°C and ≤ 37.5°C; resting pulse rate ≥ 50 beats per minute (bpm) and ≤ 100 bpm; systolic blood pressure (SBP) ≥ 90 and ≤ 139 mmHg, diastolic blood pressure (DBP) ≥ 50 and ≤ 89 mmHg, taken in supine position after resting at least 5 minutes. On Day -1, blood pressure and pulse rate need to be within the normal ranges or not clinically significant range, as per investigator's judgement.
• • Individualized estimated glomerular filtration rate (eGFR): \[(CKD-EPI ÷ 1.73) × BSA\] ≥ 90 mL/min and \< 160 mL/min for males or \< 150 mL/min for females at Screening.
• • Sufficient venous access for i.v. infusion and PK samplings.
• Exclusion Criteria:
• • History of any clinically relevant gastrointestinal, renal, hepatic, bronchopulmonary, neurological, psychiatric, cardiovascular, endocrine, hematologic, neuromuscular or allergic disease(s), metabolic disorder, cancer (may have had basal or squamous cell carcinoma of skin or cervix so long as surgically removed or deemed cured by cryotherapy, laser therapy, conization, etc, with stability for the past two years).
• • History or presence of chronic pulmonary disease.
• • Medical disorder, condition, or history of such that would - in the opinion of the Investigator - compromise the participant's ability to participate in this study.
• • Presence of any acute illness, including febrile illness with temperature \> 37.8°C (\> 100.0°F), within 7 days of Baseline (Day -1 to Day 1).
• • Known severe allergies, non-allergic drug reactions, or multiple drug allergies requiring intranasal or systemic corticosteroids during any time of the year or history of any anaphylactic reaction.
• • Known hypersensitivity to meropenem and or ANT3310 or any of the excipients of the infusion solution.
• • Known history of clinically significant hypersensitivity or urticaria, or severe allergic reaction to β-lactam antibiotics (i.e., penicillin, cephalosporin, carbapenem, or monobactam).
• • History of significant bleeding within the past 3 months.
• • History of COVID-19 within three (3) months prior to Screening.
• • History of epilepsy (or known seizure disorder), brain lesions or other significant neurological disorders.
• • History of Gilbert syndrome.
• • History of any severe antibiotic-associated superinfections, such as Clostridium difficile colitis and/or frequent fungal vaginal infections.
• • Contraindications to bronchoalveolar lavage or suspected intolerability to medications necessary for bronchoscopy, hypoxemia, reactive airway disease or asthma, unstable angina or acute myocardial infarction in the last 6 months, heart failure, and severe hemostatic alterations. Anatomical or anticipated technical difficulties that would prevent bronchoscopy or BAL procedure. Allergies to lidocaine.
