Overview
Brief Summary
The goal of this clinical trial is to test in patients with local advanced/metastatic solid tumors. the main questions it aims to answer are:
- to assess the safety and tolerability of BB-1709.
- to determine the maximum tolerated dose(MTD) and/or the PR2D of BB-1709
Detailed Description
The study consists of two parts: dose-escalation (Phase Ia) and dose expansion (Phase Ib). Phase Ia is a multicenter, open-label, first time in human clinical trial to assess safety, tolerability, pharmacokinetics, immunogenicity, the preliminary anti-tumor activity of BB-1709, and to establish the MTD and/or RP2D of BB-1709 in patients with advanced solid tumors. Phase Ib is to explore one or more RP2Ds to further assess safety, tolerability, pharmacokinetics, immunogenicity, and preliminary anti-tumor activity of BB-1709 in patients with specific types of solid tumor.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Willing and able to provide written informed consent form (ICF) for the trial. Adult patients ≥ 18 years at the time of signing ICF.
- •Histologically or cytologically confirmed unresectable locally advanced or metastatic solid tumors in patients who must have progressed on, be refractory to, or intolerant to prior SOC.
- •At least one measurable lesion as defined per RECIST Version 1.
- •Be able to provide archived or fresh tumor tissue specimens.
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 or
- •Life expectancy ≥12 weeks.
Exclusion Criteria
- •Receiving anti-tumor therapy (systemic anti-tumor therapies, immunotherapy, biotherapy, topic therapy, other investigational product, radiation therapy, or surgery) within 4 weeks prior to the first dose of study treatment; receiving anti-tumor small-molecule agents within 2 weeks or 5 half-lives (whichever is longer) prior to the first dose of study treatment; receiving anti-tumor Chinese traditional medication and herbal remedies within 2 weeks prior to the first dose of study treatment.
- •Prior history of other malignancies within the previous 3 years, except for noninvasive malignancies such as cervical carcinoma in situ, in situ prostate cancer, non-melanomatous carcinoma of the skin, ductal carcinoma in situ of the breast that has been surgically cured.
- •Major surgery or significant traumatic injury within 4 weeks before the first dose of study treatment or not fully recovered from surgery; or surgery planned during the study.
- •Not recovered to baseline or CTCAE v5.0 ≤ grade 1 AEs from prior anti-cancer therapy except for alopecia, or asymptomatic and clinically not significant laboratory abnormalities.
- •Grade 2 or greater peripheral neuropathy (PN) when signing ICF, or history of grade 3 neurotoxicity or PN, or history of treatment discontinuation due to neurotoxicity or PN.
- •Active pneumonitis/interstitial lung disease (ILD), or history of radiotherapy to lung field within 12 months before the first dose of study treatment, or current lung disease with clinical symptoms(e.g., symptomatic chronic obstructive pulmonary disease or dyspnea)
- •Symptomatic or untreated central nervous system (CNS) metastases, or CNS metastases or leptomeningeal disease or carcinomatous meningitis requiring ongoing treatment for CNS metastases, including surgery or radiation therapy or steroids (\>10 mg/day of prednisone or equivalent) and antiepileptic agents.
- •Uncontrolled ascites, pleural effusion or pericardial effusion, as determined by the Investigator.
- •Active autoimmune disease, except vitiligo or cured childhood asthma/allergies that requires no intervention after adulthood, autoimmune-mediated hypothyroidism treated with stable doses of thyroid hormone replacement, or Type I diabetes treated with stable doses of insulin can be excepted.
- •History of organ transplantation (i.e., stem cell or solid organ transplant).
Arms & Interventions
dose escalation
BB-1709 will be administered as an intravenous infusion by Q3W or Q2W as long as they continue to show clinical benefit as judged by the investigator, until disease progression or intolerable toxicity, withdrawal of consent, death, or termination of the study.
Intervention: BB-1709
dose expansion
BB-1709 will be administered as an intravenous infusion by Q3W or Q2W as long as they continue to show clinical benefit as judged by the investigator, until disease progression or intolerable toxicity, withdrawal of consent, death, or termination of the study.
Intervention: BB-1709
