Phase 1a/1b First-in-Human Study of BG-C9074 Alone and in Combination With Other Anticancer Therapies in Patients With Advanced Solid Tumors
What this study is about
This is a first-in-human, dose finding and dose expansion study to evaluate the safety, tolerability, how the drug moves through the body (PK), how the drug affects the body, and preliminary antitumor activity of BG-C9074 alone and in combination with other anticancer therapies in patients with advanced solid tumors.
View original scientific description
This is a first-in-human, dose finding and dose expansion study to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of BG-C9074 alone and in combination with other anticancer therapies in patients with advanced solid tumors.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Able to provide a signed and dated written informed consent prior to any study-specific procedures, sampling, or data collection.
- Eastern Cooperative Oncology Group (ECOG) Performance Status ≤ 1.
- Participants with selected histologically or cytologically confirmed advanced, metastatic, and unresectable solid tumors who have previously received standard systemic therapy and whose cancer is not amenable to therapy with curative intent, and for whom further treatment is not available or not tolerated. Enrollment will be limited to participants with hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) breast cancer, cholangiocarcinoma (CCA), endometrial cancer, squamous non-small cell lung cancer (NSCLC), triple-negative breast cancer (TNBC), or ovarian cancer. Enrollment in the Japan cohort will be limited to participants with HR+/HER2- breast cancer, TNBC, endometrial cancer, or ovarian cancer.
- ≥ 1 measurable lesion per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1)
- Able to provide an archived tumor tissue sample.
- Adequate bone marrow and organ function.
- Females of childbearing potential must be willing to use a highly effective method of birth control for the duration of the study, and for ≥ 7 months after the last dose of study drug(s).
- Nonsterile males must be willing to use a highly effective method of birth control for the duration of the study treatment period and for ≥ 4 months after the last dose of study drug(s).
Exclusion criteria
- Prior treatment with a B7 homolog 4 (B7H4)-targeting antibody-drug conjugate (ADC) or an ADC with a topoisomerase 1 inhibitor (TOP1i) payload.
- Active leptomeningeal disease or uncontrolled, untreated brain metastasis
- Any malignancy ≤ 2 years before the first dose of study treatment(s) except for the specific cancer under investigation in this study and any locally recurring cancer that has been treated with curative intent (eg, resected basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix or breast).
- History of interstitial lung disease, ≥ Grade 2 noninfectious pneumonitis, oxygen saturation at rest \< 92%, or requirement for supplemental oxygen (including intermittent use) at baseline.
- Uncontrolled diabetes.
- Infection (including tuberculosis infection) requiring systemic (oral or intravenous) antibacterial, antifungal, or antiviral therapy ≤ 14 days before the first dose of study treatment(s). Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
