Phase 1 Study of LNCB74 Antibody Drug Treatment for Advanced Solid Tumors Including Ovarian, Breast, Endometrial, Biliary Tract, and Non-Small Cell Lung Cancer

What this Trial Is About

Researchers are evaluating LNCB74, an antibody drug conjugate, in participants with advanced solid tumors including ovarian, breast, endometrial, biliary tract, and non-small cell lung cancers. This phase 1, open-label study aims to determine the safety, tolerability, and the recommended dose for future studies by escalating doses and expanding treatment in selected tumor types. The study is sponsored by NextCure, Inc. and focuses on participants with measurable disease and adequate organ function. Participants will receive LNCB74 intravenously every 21 days in two parts Part 1 involves dose escalation to find the maximum tolerated dose or recommended phase 2 dose, with additional safety and biomarker assessments. Part 2 involves dose expansion and optimization to further evaluate safety, tolerability, anti-tumor activity, and pharmacodynamics in a more uniform group of participants. Treatment continues unless unacceptable side effects or clear disease progression occur. During the study, participants will undergo regular safety and response evaluations including tumor assessments, biomarker analysis, and pharmacokinetic measurements. Key outcomes include safety, tolerability, response rates, and progression-free survival over up to 24 months. Blood samples will be taken to study drug levels and immune response. Participants are monitored closely for adverse effects and effectiveness, with a minimum life expectancy of 12 weeks required to join.
