Is this trial a fit for you?

Likely a 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.

Probably 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.

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.

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 gone: 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.
