Phase 1
Recruiting
Conditions
Pancreatic Ductal Adenocarcinoma
Non-small Cell Lung Cancer
Colorectal Cancer
Advanced Solid Tumor
Metastatic Solid Tumor
Interventions
Registration Number
NCT06607185
Lead Sponsor
Eli Lilly and Company
Brief Summary

The main purpose of the study is to assess whether the study drug, LY4066434, is safe and tolerable when administered to participants with locally advanced or metastatic solid tumors with certain KRAS mutations. LY4066434 will be given alone or in combination with other treatments. The study will have 2 parts: monotherapy dose escalation and dose optimization. The study is expected to last up to approximately 5 years.

Primary Outcome Measures
NameTimeMethod
Number of Participants with Dose-limiting Toxicities (DLTs)During the first cycle of LY4066434 treatment (up to 28 days)
Number of Participants with One or More Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug AdministrationUp to approximately 5 years

A summary of TEAEs, SAEs and other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module.
