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

Recruiting now · Phase 1

Conditions studied: Advanced Malignancies

In brief

This is a Phase I, multicenter, open-label, single-arm and first-in-human clinical study of BRY812 for injection. The study objectives are to evaluate the safety, tolerability, pharmacokinetic profile, anti-tumor activity and immunogenicity of BRY812 for injection in patients with advanced malignancies. Patients will receive treatment every 3 weeks until intolerable toxicity, disease progression, pregnancy, withdrawal of informed consent, death, study discontinuation, or withdrawal from the study.

You may qualify if…

(1) Subjects who voluntarily sign the informed consent form, understand the nature, objectives, and procedure of the study and are able to complete the study according to the protocol;
(2) Male or female patients, ≥ 18 years of age (based on the date of signing the informed consent form);
(3) In Phase Ia: patients must have advanced solid tumors confirmed by histopathology and/or cytology, who have failed to respond to standard-of-care (disease progression after treatment) or who could not tolerate standard-of-care, or who could not obtain effective standard-of-care or for whom there was no effective standard-of-care available; (Note: the patient population and inclusion criteria in phase Ib will be determined according to the data of phase Ia);
(4) According to RECIST v1.1 (Response Evaluation Criteria in Solid Tumors), there is at least 1 measurable lesion;
(5) Eastern Cooperative Oncology Group (ECOG) Status 0 to 1;
(6) Adequate organ and bone marrow function (no treatment with cells, growth factors, or transfusions within 14 days prior to the first administration), as defined below:
Hematology: absolute neutrophil count (ANC) ≥ 1.5 × 109/L, platelet count (PLT) ≥ 100 × 109/L, hemoglobin (HGB) ≥ 90 g/L;
Liver function: serum total bilirubin (TBIL) ≤ 1.5 × upper limit of normal (ULN) (except for subjects with Gilbert syndrome, TBIL ≤ 2 × ULN in patients with liver cancer or liver metastases), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN (in patients with liver cancer or liver metastases, ALT or AST ≤ 5 × ULN);
Renal function: creatinine (Cr) ≤ 1.5 × ULN or creatinine clearance (CrCL) (based on Cockcroft-Gault equation) ≥ 60 mL/min;
(7) Expected survival ≥ 12 weeks;
(8) Female subjects with fertility potential must test negative for serum human chorionic gonadotropin (HCG) before they are enrolled in the study. Female subjects with fertility potential or male subjects who have a female partner must agree to maintain no pregnancy plan and take effective contraceptive measures such as condoms from the signing of ICF to 6 months after the last dose of study drug (see Annex 1 for details); females are considered fertile from menarche to menopause (at least 12 months without menstruation) unless they are permanently infertile (through hysterectomy, bilateral salpingectomy, or bilateral oophorectomy).

You may not qualify if…

(2) Subjects who have previously received drugs which target LIV-1;
(3) Subjects who have any active infection requiring systemic therapy by intravenous infusion within 2 weeks prior to the first dose of study drug;
(4) Subjects who have previous or current presence of two or more primary tumors (excluding cured cervical carcinoma in situ, basal cell carcinoma, or squamous cell carcinoma of the skin, and other tumors that have been stable for more than 5 years after treatment);
(5) Subjects who have symptoms of active central nervous system metastases, except those with brain parenchymal metastases assessed as stable by the investigator based on the following conditions:
No seizures within > 12 consecutive weeks with or without the treatment of antiepileptic drugs;
Glucocorticoids are not required;
Two consecutive MRI scans (at least 4 weeks apart) show a stable state on imaging;
Asymptomatic inactive brain metastases are newly identified where two consecutive MRI scans (at least 4 weeks apart) show a stable state on imaging;
The conditions remain stable and asymptomatic for more than 1 month after treatment;
(6) Subjects with serious cardiovascular and cerebrovascular diseases and lung diseases, including but not limited to:
Stroke, intracranial hemorrhage, unstable angina pectoris, congestive heart failure (NYHA class III-IV), myocardial infarction, severe arrhythmias (such as sustained ventricular tachycardia and ventricular fibrillation), congenital long QT syndrome, torsade de pointes, and symptomatic pulmonary embolism within 6 months before enrollment;
Uncontrolled hypertension (at least 2 consecutive measurements of systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥ 100 mmHg);
Echocardiogram (ECHO) or multigated acquisition scan (MUGA) shows left ventricular ejection fraction (LVEF) < 50%;
During the screening period, the mean corrected (by Fridercia's formula) QT interval on three consecutive electrocardiograms is prolonged (> 450 ms in males and > 470 ms in females);
Subjects who have interstitial lung diseases, severe impaired lung function, severe pulmonary fibrosis, radiation pneumonitis, and other lung diseases assessed by the investigator as clinically significant;
(7) Subjects who have active gastrointestinal bleeding or severe intestinal obstruction;
(8) Subjects who have undergone major surgery within 4 weeks prior to the first dose of study drug or are expected to be performed during the study;
