A Phase I Study of BRY812 for Injection Alone in Subjects With Advanced Malignancies

BRY812 for injection will be administered by intravenous drip, tentatively once per cycle spanning 3 weeks on D1 of each cycle until intolerable toxicity, disease progression, pregnancy, withdrawal of informed consent, death, study discontinuation or withdrawal from the study. The dose of each administration will be calculated based on the weight measured prior to such administration. The dosing regimen (dosing frequency and interval) for subsequent study may be adjusted based on prior data. The intravenous drip should last for ≥ 90 min for the first dose and may be adjusted to ≥ 30 min for subsequent doses if the first dose is tolerable.
