What this Trial Is About

Researchers are evaluating BSY001 for injection in healthy adults aged 18 to 50 years to assess its safety, tolerability, and how the body processes the drug. This Phase I clinical trial includes two parts: a single-dose study and a multiple-dose study. The study is randomized, double-blind, and placebo-controlled to carefully monitor the effects of BSY001 compared to placebo. It is sponsored by China National Biotec Group Company Limited. The first part, BSY001-A, involves giving single ascending doses of BSY001 or placebo in five groups ranging from 37.5 mg to 300 mg. Each group receives one dose followed by blood tests and safety checks, with dosing of higher groups starting only after safety is confirmed. The second part, BSY001-B, enrolls 30 participants who receive 200 mg of BSY001 or placebo twice daily for 14 days under close hospital supervision, with regular blood sampling and safety assessments. Participants will undergo screening and then receive either BSY001 or placebo according to their group. Blood samples are collected at multiple time points to study how the drug behaves in the body. Safety is assessed through physical exams, vital signs, lab tests, electrocardiograms, and monitoring for side effects. The study lasts through dosing and follow-up periods, with detailed evaluation of drug levels and tolerability up to 20 days after dosing.

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Single-Dose Treatment

Duration - Up to 10 days per dose group

Participants receive a single dose of BSY001 or placebo in one of five ascending dose groups. Pharmacokinetic blood samples and safety assessments are collected. Tolerability is assessed on Day 4 for each dose group before the next dose group begins.

Multiple visits including Day 1 dosing and follow-ups on Days 4 and 10

Multiple-Dose Treatment

Duration - 14 days

Participants receive 200 mg of BSY001 or placebo every 12 hours for 14 consecutive days under centralized management with scheduled blood sample collection and safety assessments.

Daily visits during hospitalization for dosing and assessments

Follow-up

Duration - Up to 10 days after dosing for single-dose cohorts; up to 6 days after dosing for multiple-dose cohort

Participants are monitored for safety and tolerability after completion of dosing, including laboratory tests, physical exams, and vital signs assessments.

Follow-up visits on Days 10 and 20 as applicable
