| Patients Enrolled |
Eligible adults (≥18) have advanced solid tumors (measurable per RECIST 1.1/RANO 2.0), ECOG 0-1, LVEF ≥50%, and adequate organ function. Exclusions: prior B7-H3/TOP1-ADC therapy, uncontrolled cardiac/pulmonary conditions (e.g., CHF, ILD), active infections (HBV/HCV exceptions), untreated CNS metastases, or unresolved Grade ≥2 toxicity. Contraception is mandatory (7 months for females, 4 for males). Cohort-specific criteria apply (e.g., SCLC: prior platinum therapy; CRPC: progression per PCWG3).

| Clinical Description | A Phase 1/2a, Multicenter, Open-Label, First in Human Study to Assess the Safety, Tolerability, Pharmacokinetics, and Preliminary Antitumor Activity of DB-1311 in Subjects With Advanced/Metastatic Solid Tumors | ||||
| Primary Endpoint |
The Phase 1 study assesses DLTs (first 21 days), MTD/RP2D determination (over 12 months), and safety profile (TEAEs/SAEs per CTCAE v5.0 over ~1 year). Phase 2a evaluates ORR by RECIST 1.1 (non-CRPC/non-GBM), PCWG3 (CRPC bone metastases), or RANO 2.0 (GBM), alongside continued safety monitoring.
|
||||
| Other Endpoint |
Key secondary endpoints include ORR, DOR, DCR, TTR, PFS, OS (tracked for ~1 year), and PSA dynamics in CRPC. PK parameters (AUC, Cmax, Tmax, Ctrough) are analyzed over 8 cycles (21 days/cycle), alongside ADA prevalence/incidence. Tumor response criteria vary by cohort (RECIST 1.1, PCWG3, RANO 2.0).
