Brief Summary

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

This is a dose-escalation and dose-expansion Phase 1/2a trial to evaluate the safety and tolerability of DB-1310 in subjects with advanced solid tumors.

Detailed Description

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

This is a multicenter, open-label, multiple-dose, FIH Phase 1/2a study. Phase 1 adopts the standard "3+3" design to identify: the MTD and/or RP2D of DB-1310 as monotherapy, the RCD\_A of DB-1310 in combination with trastuzumab or approved trastuzumab biosimilar and the RCD\_B of DB-1310 in combination with Osimertinib; Phase 2a is a dose expansion phase to confirm the safety, tolerability and explore efficacy in selected malignant solid tumors treated with DB-1310 as monotherapy or in combination with trastuzumab or approved trastuzumab biosimilar or in combination with Osimertinib.

11. Has clinically significant corneal disease.
12. Know human immunodeficiency virus (HIV) infection.
13. Subjects have active viral (any etiology) hepatitis are excluded. However, subjects with positive hepatitis B surface antigen (HBsAg) who have the HBV DNA (viral load) below the lower limit quantification or HBV DNA titer \< 1000 cps/mL or 100 IU/mL per local testing and are not currently on viral suppressive therapy may be eligible and should be discussed with the Sponsor's Medical Monitor. However, subjects with a history of hepatitis C virus (HCV) infection who have completed curative antiviral treatment and have the HCV RNA below the lower limit of quantification per local testing are eligible for study entry.
14. Is a lactating mother (women who are willing to temporarily interrupt breastfeeding will also be excluded), or pregnant as confirmed by serum pregnancy tests performed within 7 days prior to Cycle 1 Day 1.
15. Has clinically active brain metastases, defined as untreated and symptomatic, or requiring therapy with steroids or anticonvulsants to control associated symptoms. However, subjects with asymptomatic central nervous system (CNS) metastases who are radiologically and neurologically stable for at least 4 weeks following CNS-directed therapy, and who are on stable or decreasing doses of corticosteroids equivalent to ≤10 mg/day prednisone are eligible for study entry.
16. Has unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to NCI-CTCAE version 5.0, grade ≤ 1 or baseline. Subjects with chronic Grade 2 toxicities (e.g., Grade 2 neuropathy) may be eligible based on the discussion and agreement between Investigator and Sponsor.
17. Has multiple primary malignancies within 3 years before enrollment, except adequately resected non-melanoma skin cancer (e.g., resected basal or squamous cell skin cancer), curatively treated in-situ disease (e.g., carcinoma in situ of the cervix or breast), other solid tumors curatively treated (e.g., superficial bladder cancer), or contralateral breast cancer.
18. Has substance abuse or any other medical conditions that would increase the safety risk to the subject or interfere with participation or evaluation of the clinical study in the opinion of the investigator.
19. Has known hypersensitivity to either the drug substances or inactive ingredients in the drug product.
