A Phase I Study of BR115 for Injection Alone in Subjects With Advanced Solid Malignancies

BR115 for injection will be administered by subcutaneous injection, two doses at the first week of treatment, followed by once per week 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.
