Patients Enrolled
Inclusion: Adults (≥18) with advanced/metastatic solid tumors (RECIST 1.1-measurable), ECOG 0-1, life expectancy ≥12 weeks, adequate organ function, willingness for biopsies, and contraception compliance. Exclusion: Prior MMAE-ADC therapy, platinum-refractory disease, active CNS metastases, Grade≥2 neuropathy/corneal disease, uncontrolled infections (HIV/HBV/HCV), recent anticancer therapies (chemotherapy within 2 weeks, antibodies within 4 weeks, radiotherapy within 2-4 weeks), immunosuppression, or significant comorbidities (cardiovascular, interstitial lung disease, bowel obstruction). Pregnancy, breastfeeding, or unresolved toxicities (>Grade 1) also exclude participation.

Administration Dosage
LNCB74 is an antibody drug conjugate being evaluated as a potential treatment for participants with advanced solid tumors. Participants will receive LNCB74 into the vein (IV; intravenously) in 21-day dosing cycles. Participants will continue treatment in the absence of unacceptable toxicities and unequivocal disease progression.

NCT Number NCT06774963  Clinical Status PHASE1
Clinical Description
A Phase 1, Open-label, Dose Escalation and Dose Expansion Study for LNCB74, a B7-H4 Targeted Antibody Drug Conjugate, as Monotherapy in Participants With Advanced Solid Tumors
Primary Endpoint
The study aims to evaluate the safety and tolerability of LNCB74 over 24 months, assessing incidence of AEs, SAEs, DLTs, discontinuations, and deaths per NCI CTCAE v5.0. Additionally, it seeks to determine the RP2D (based on MTD, MAD, and cumulative safety/PK data) and define the maximum tolerated/feasible dose.
Other Endpoint
Efficacy measures include ORR, DOR, DCR, and PFS at 6/24 months (per RECIST 1.1), alongside correlations between B7-H4 expression (via central IHC) and clinical outcomes (ORR, DOR, DCR, PFS). Pharmacokinetics (Tmax, AUC, T1/2, Cmax) are evaluated across multiple cycles (Days 1-15, Cycles 1-9). Immunogenicity (anti-drug antibodies) is monitored for 24 months.
