First look: can a new drug candidate pass early safety tests in humans?
NCT ID NCT07736638
First seen Jul 30, 2026 · Last updated Aug 04, 2026 · Updated 3 times
Summary
This early-stage trial is testing a single dose of an experimental drug called ABBV-859 in 64 healthy adults. The goal is to see how the body processes the drug, whether it causes side effects, and whether the immune system reacts to it. Participants receive either the drug or a placebo, given as a pill or through an IV. No therapeutic benefit is expected — the study is purely about safety and basic drug behavior.

Inclusion Criteria: * Participants must voluntarily sign and date an informed consent, approved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB), prior to the initiation of any screening or study-specific procedures. * Body Mass Index (BMI) is \>= 18.0 to \<= 32 kg/m2 after rounding to the tenths decimal at screening. BMI is calculated as weight in kg divided by the square of height measured in meters. * A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile and a 12-lead Electrocardiogram (ECG). Exclusion Criteria: * History of epilepsy, any clinically significant cardiac, respiratory (except mild asthma as a child), renal, hepatic, gastrointestinal, hematologic, endocrine, immunological, pulmonary, metabolic, neurological or psychiatric disease or disorder, or any uncontrolled medical illness. * History of any clinically significant sensitivity or allergy to any medication or food. * History of or active medical condition(s) or surgical procedure(s) that might affect gastrointestinal motility, pH, or absorption \[e.g., Crohn's disease, celiac disease, gastroparesis, short bowel syndrome, gastric surgery (except pyloromyotomy for pyloric stenosis during infancy), cholecystectomy, vagotomy, bowel resection, etc.\]. * Evidence of dysplasia or history of malignancy (including lymphoma and leukemia) other than successfully treated non-metastatic cutaneous squamous cell, basal cell carcinoma or localized carcinoma in situ of the cervix. * History or evidence of active Tuberculosis disease or latent Tuberculosis infection.
