BAL2420 safety and dosing in healthy adults

A First-in-Human, Randomized, Dose-escalation, Double-blind, Placebo-controlled Study to Investigate Safety, Tolerability, and Pharmacokinetics of BAL2420 Administered to Healthy Adult Subjects

Phase 1 Interventional Basilea Pharmaceutica · NCT07500181

This trial will test how safe BAL2420 is and how the body absorbs and clears different single and repeated doses in healthy adult volunteers.

What this trial studies

Basilea is conducting a randomized, double-blind, placebo-controlled Phase I study of BAL2420 in healthy adult volunteers to characterize safety, tolerability, and pharmacokinetics. Part A uses single ascending doses while Parts B and C use multiple ascending doses, with each cohort randomized to BAL2420 or matched placebo. Serial blood sampling, ECGs, and laboratory safety tests will be used to measure pharmacokinetics and detect adverse events. The study is conducted at an early clinical site in Groningen with sponsorship from Basilea and support from CARB-X.

Who should consider this trial

Good fit: Ideal candidates are healthy adult volunteers who meet entry criteria (for example, BMI 18–30 kg/m2 and body weight >50 kg) and have no active illness, significant medical history, or recent use of excluded medications.

Not a fit: Patients with active infections, significant comorbidities, or those needing immediate antibiotic therapy are unlikely to receive direct clinical benefit from this early safety study.

Why it matters

Potential benefit: If successful, BAL2420 could become a new treatment option for severe infections caused by Gram-negative bacteria, especially where resistance limits current choices.

How similar studies have performed: Testing safety and pharmacokinetics of investigational antibiotics in healthy volunteers is a standard early-phase approach that has supported development of several approved antibacterial drugs, though BAL2420 itself remains investigational.
