New drug SPH9788 begins first human safety tests
NCT ID NCT06839131
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial is testing the safety of a new drug called SPH9788 in 94 healthy Chinese adults aged 18 to 45. Participants will receive either the drug or a placebo, and researchers will monitor for side effects and how the drug moves through the body. The goal is simply to see if it is safe enough to study further—not to treat any disease.
