Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ranged 18-70 years (including the boundaries) when signed informed consent form (ICF)
• Has a life expectancy of ≥ 3 months
• Phase Ia: patients with advanced malignant solid tumor who:
• have progressed on or are intolerant to standard therapy, or
• no standard therapy exists
• Phase Ib disease specific Cohorts:
• Cohort 1: Platinum-resistant advanced high-grade serous ovarian cancer, fallopian tube cancer or primary peritoneal cancer.Platinum resistance was defined as progression or recurrence within 6 months after the last dose of platinum. Patients with primary platinum refractory disease are excluded
• Cohort 2: Metastatic triple-negative breast cancer
• Based on most recently analyzed biopsy or other pathological specimens, TNBC was confirmed histologically or cytologically
• Patients have received at least 2 previous systemic chemotherapy regimens for local advanced/metastasis disease. If the patients in the early phase develop into unresectable locally advanced or metastatic disease within 12 months after adjuvant or neoadjuvant chemotherapy, the regimens will be regarded as one of the previous systemic chemotherapy regimens
• Cohort 3: Patients with other advanced solid tumor types who failed from standard therapy or no standard therapy exists or intolerant to the existing treatment, such as: Esophageal squamous cell carcinoma, Non-triple-negative breast cancer, head and neck squamous cell carcinoma, lung squamous cell carcinoma, gastric adenocarcinoma, colon cancer, cervical cancer, endometrial cancer, and so on
• Cohort 4: Other types of ovarian cancer that are resistant to platinum (clear cell carcinoma and/or low-grade serous carcinoma, etc.)
• Has an Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1
• At least 1 measurable tumor lesion according to RECIST v1.1
• Archived tumor tissue samples available or fresh tumor biopsy samples available
• FOLR1 and/or TRPV6 receptor expression tested positive by the central laboratory
• The time window from the last administration of previous anti-tumor therapy to the first administration of CBP-1008 in this study was at least 28 days. No other trial drugs or experimental instruments was used or other clinical trials were conducted within 28 days before the start of trial drugs
• According to the NCI-CTCAE 4.03 version, the acute toxicity of any previous treatment, surgery or radiotherapy must have been alleviated to grade 0 or 1
• Adequate hematologic status (without receiving blood transfusion and growth factor support within 2 weeks before enrollment), defined as:
• Absolute neutrophil count (ANC) ≥ 1.5× 109/L
• Platelet count ≥ 90 × 109/L
• Hemoglobin (Hb) ≥ 95 g/L
• Adequate hepatic function, defined as:
• Serum total bilirubin (TBIL) ≤ 1.5× ULN, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5× ULN if no demonstrable liver metastases (ALT and AST ≤ 3.0× ULN in the presence of liver metastases)
• Adequate renal function, defined as:

You may not qualify if…

• Concurrent malignancy(ies) within 3 years prior to screening other than adequately treated cervical carcinoma-in-situ, skin cancer of basal cell or squamous cell carcinoma, local prostate cancer after radical operation, ductal carcinoma in situ after radical operation
• History of epilepsy
• Active or symptomatic central nervous system metastasis and / or cancerous meningitis with the exception of, asymptomatic or stable brain metastases
• History of congestive heart failure of the New York Heart Association Functional Classification III/IV, unstable angina pectoris, persistent atrial fibrillation, ventricular arrhythmia or conduction block; with risk factors for, or are receiving medications known to prolong QT interval, refractory hypertension (except hypertension patients whose blood pressure is controlled below 140 / 90mmHg by drugs)
• Significant surgical interventions within 21 days prior to the first dose of CBP-1008 or with ongoing post-operative complications
• Radiotherapy administrated within 21 days prior to the first dose of CBP-1008
• Interstitial lung disease, non-infectious pneumonia or a history of poorly controlled systemic diseases, including diabetes, hypertension, pulmonary fibrosis, acute lung disease, etc
• Active infections requiring systemic treatment, active viral hepatitis or active tuberculosis
• Pericardial effusion with important clinical significance
• Clinically uncontrolled pleural effusion or ascites requiring drainage within 1 month before administration
• ≥level 2 Peripheral neuropathy, according to NCI CTCAE 4.03 criteria
• For subjects with lung squamous cell carcinoma, there was hemoptysis within 28 days prior to the first dose of CBP-1008 (hemoptysis volume ≥ 2.5ml each time)
• A history of gastrointestinal perforation and / or complete intestinal obstructio within 6 months prior to the first dose of CBP-1008
• There is higher risk of bleeding or fistula caused by the adjacent organs of esophageal lesions (large artery or trachea) invaded by the tumor. Subjects after endotracheal stent implantation
• Foods or drugs known as potent or moderate CYP3A inhibitors or potent CYP3A inducers which has been used 10 days before the first dose or is expected to use
• Female subject who are pregnant or breastfeeding or considering pregnancy
• Any medical situation assessed by the researcher may increase the patient's safety risk, limit study compliance or interfere with study evaluation
• Alcoholism within 3 months prior to the first dose of CBP-1008
• Known drug abuse within 6 months before signing ICF
• Human immunodeficiency virus infection (HIV-1/2 antibody positive), active hepatitis B virus (HBV) infection，hepatitis C virus (HCV) infection (HCV antibody positive) or syphilis infection. Active hepatitis B was defined as HBV DNA ≥ upper limit of laboratory normal reference range
