Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A Phase II, Multicenter, Open-Label Trial of DB-1311 in combination with BNT327 or DB-1305 in Participants with Advanced/Metastatic Solid Tumors

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a phase II, multicenter, open-label, two-part trial designed to evaluate the safety and preliminary efficacy of DB-1311 in combination with BNT327 or DB-1311 in combination with DB-1305 in targeted participants.

Participants with recurrent, progressive as well as advanced, metastatic hepatocellular carcinoma (HCC), cervical cancer (CC), melanoma, head and neck squamous cell carcinoma (HNSCC), platinum-resistant ovarian cancer (PROC) or non-small cell lung cancer (NSCLC) are eligible to participate in the trial.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adults aged ≥ 18 years or acceptable age according to local regulations at the time of voluntarily signing informed consent.
* At least one measurable lesion as assessed by the Investigator according to RECIST v1.1 criteria.
* Has a life expectancy of ≥ 3 months.
* Has an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-1
* Has adequate organ function within 7 days prior to enrollment/randomization,
* Has adequate treatment washout period prior to the first dose of trial treatment.

* For HCC patients: Histological/cytological confirmed diagnosis of HCC or clinically confirmed diagnosis of HCC; Has a Child-Pugh class A liver score.
* For CC patients: Has persistent, recurrent or metastatic cervical cancer with squamous cell, adenocarcinoma, or adenosquamous histology
* For Melanoma patients: Histologically or cytologically confirmed diagnosis of unresectable Stage III or metastatic melanoma.
* For PROC patients (Cohort A): Participants must have a confirmed diagnosis of OC, primary peritoneal cancer, or fallopian tube cancer, all of which with high-grade serous histology. Patients must have platinum-resistant disease.
* For HNSCC patients: Histologically or cytologically confirmed recurrent (recurrent disease that is not amendable to curative treatment with local/ or systemic therapies)/ (disseminated) HNSCC of the oral cavity, oropharynx, hypopharynx, and larynx that is considered incurable by local therapies.
* For NSCLC patients: Pathologically documented Stage IIIB or IIIC NSCLC not amenable for radical surgery or definitive chemoradiation or Stage IV NSQ NSCLC. Not harboring an EGFR-sensitizing mutation or ALK gene rearrangements or other onco-driver gene mutations

Exclusion Criteria

* 1\. Prior treatment with B7H3 targeted therapy.
* Prior treatment with antibody-drug conjugate with topoisomerase inhibitor.
* Is a candidate to locoregional treatment with potential to induce complete or near complete response and prolonged tumor control, per investigator's assessment.
* Has an uncontrolled concomitant or intercurrent illness, that in the opinion of the investigator, contra-indicates trial participation, limits compliance with trial procedures or substantially increases the risk of incurring AEs.
* Has uncontrolled or significant cardiovascular disease. Has clinically uncontrolled pleural effusion, ascites or pericardial effusion requiring drainage, peritoneal shunt, or cell-free concentrated ascites reinfusion therapy.
* Has a history of (non-infectious) ILD/pneumonitis.
* Any autoimmune, connective tissue or inflammatory disorders.
* Has spinal cord compression or clinically active central nervous system (CNS) metastases.
* Has unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to Grade ≤1 or baseline.
