New antibody drug HB0043 gets first human safety check
NCT ID NCT06999083
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested the safety and tolerability of a single dose of HB0043, a lab-made antibody that targets two inflammatory proteins (IL-17A and IL-36R), in 52 healthy adults aged 18 to 55. Participants received either the drug or a placebo, and researchers monitored for side effects and how the drug moved through the body. Since this is an early Phase 1 trial, it does not test whether the drug treats any disease—only that it is safe enough to study further.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- HB0043 (a bispecific antibody targeting IL-17A and IL-36R)
- What this could lead to
- If successful, this could pave the way for future studies of HB0043 in inflammatory diseases like psoriasis or arthritis.
- What could go wrong
- This is an early Phase 1 trial in healthy volunteers, so it only tests safety and dosing—not whether the drug works for any disease. Side effects are possible.

Normal ECG, blood pressure, respiratory rate, temperature and heart rate, unless the investigator considers any abnormality to be not clinically significant. 7. Informed consent must be obtained for all subjects enrolled into the study. Exclusion Criteria: Subjects who meet any of the following criteria will be excluded from study entry: 1. History of clinically significant cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, psychiatric or neurological disease. 2. Current or history of malignancy. 3.

Donation of plasma within 7 days prior to dosing or donation or loss of 500 mL or more of whole blood within 8 weeks prior to dosing 8. Had a vaccination with a live attenuated vaccine within 1 months prior to dosing. 9. Subjects at risk for tuberculosis (TB), specifically subjects with: * Current clinical, radiographic or laboratorial evidence of active TB; * Positive interferon-γ release assay (IGRA) test. 10. Positive test at screening for any of the following infectious disease tests: Hepatitis B, surface antigen (HBsAg), Hepatitis C virus antibody (HCV Ab), Human immunodeficiency virus antibody (HIV Ab). 11. History of clinically significant opportunistic infection (e.g., invasive candidiasis or pneumocystis pneumonia). 12. A helminth parasitic infection diagnosed within 6 months prior to screening that has not been treated with, or has failed to respond to, standard of care therapy. 13.

History of drug abuse within 1 year prior to screening, or use of soft drugs (such as marijuana) within 3 months prior to the screening, or hard drugs (such as cocaine, phencyclidine, and crack) within 1 year prior to screening. Positive drug screen (cocaine, methamphetamine, phencyclidine, and Tetrahydrocannabinol) at screening or Day -1. 16. History of regular alcohol consumption exceeding 14 drinks/week for female subjects or 21 drinks/week for male subjects (1 drink = 5 ounces \[150 mL\] of wine or 12 ounces \[360 mL\] of beer or 1.5 ounces \[45 mL\] of hard liquor) within 6 months before screening. Positive Breath Alcohol Test at screening or Day -1. 17. Current cigarette smoker (cigarettes or e-cigarettes) who smoke over 5 cigarettes/day within 3 months prior to screening. 18. Mental condition rendering the subject incapable of understanding the nature, scope, and possible consequences of the study. 19. Pregnant or Breasting feeding subject. Women with positive pregnancy test (hCG). Or subjects who plan to donate sperms or eggs, from dosing until at least 6 months after last dose of investigational medicine. 20. Adults under guardianship and people with restriction of freedom by administrative and legal decisions. 21. Unlikely to comply with the clinical study protocol, e.g. uncooperative attitude, inability to return for followed-up visit, and improbability of completing the study. 22.
