A Study to Evaluate ELU001 in Patients With Solid Tumors That Overexpress Folate Receptor Alpha (FRα)

The study had two parts: Part 1 Dose Escalation Safety Study to identify the maximum tolerated dose (MTD) and/or the recommended phase 2 dose (RP2D), and Part 2 Tumor Group Expansion Cohort(s) where specific cancer types will be evaluated for efficacy and safety at the RP2D. Part 1, subjects with cancer types with a high likelihood of having FRα overexpressing tumors based on historical data, specifically, ovarian, endometrial, colorectal, gastric, gastroesophageal junction, triple negative breast, or non-small cell lung cancers, or cholangiocarcinoma, will be enrolled in a basket clinical study. Retrospective analysis of folate receptor alpha (FRα) expression status will be determined. Part 1 is currently closed for further recruitment. Part 2 Stage 1 of a Simon's Two-Stage design, tumor group expansion cohorts, each consisting of subjects with cancer types studied as part of the basket in Part 1. Part 2 is closed for recruitment.
