Summary

This early-phase study is testing the safety of a new drug called BIIB142 in 78 healthy adults. Participants receive either the drug or a placebo, in single or multiple doses, to see how the body handles it and whether it causes any side effects. The study is split into two parts: Part A tests a single dose, and Part B tests daily doses for 14 days.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
BIIB142
What could go wrong
This is an early phase 1 trial in healthy volunteers, so it only tests safety and how the drug moves through the body. There is no disease being treated, so success here does not guarantee any future treatment benefit.
