Phase 1 — Testing in a small group (usually 20–80 people) to find a safe dose and watch for side effects.
This is a Phase 1 trial testing BCD-261, a new experimental medication, in healthy volunteers. Researchers want to learn how safe this medication is, how the body processes it, and how the immune system responds to it. The study gives participants a single injection and watches carefully for any side effects.
Before any medication can be tested in patients with a disease, researchers must first confirm it is safe in healthy people. This trial is the earliest stage of testing this medication to find the right dose and identify any safety concerns.

Participants receive a single injection under the skin and then visit the clinic multiple times over several months for blood tests and safety check-ups. The study has two stages: in Stage 1, different groups of participants receive gradually increasing doses to find the safest amount, and in Stage 2 (if the medication is safe enough), more participants receive two specific doses chosen based on Stage 1 results. The entire study lasts about 4 months.
