Eli Lilly and Company is conducting a Phase 1a/1b clinical study titled A Phase 1a/1b Study of the Pan-KRAS Inhibitor LY4066434 in Participants With KRAS Mutant Solid Tumors. The study aims to evaluate the safety and tolerability of the investigational drug LY4066434 in patients with locally advanced or metastatic solid tumors with specific KRAS mutations. This research is significant as it explores new treatment avenues for these challenging cancer types.
The study tests LY4066434, a pan-KRAS inhibitor, administered orally. It is being evaluated both as a standalone treatment and in combination with other drugs like Cetuximab and Pembrolizumab, among others, to enhance its efficacy against KRAS mutant tumors.
This interventional study uses a non-randomized, sequential model with no masking, focusing primarily on treatment. The study comprises two parts: monotherapy dose escalation and dose optimization, aiming to refine the dosing strategy for LY4066434.
The study began on October 21, 2024, with an estimated duration of up to five years. The latest update was submitted on August 5, 2025, indicating ongoing recruitment and progress.
The outcome of this study could significantly impact Eli Lilly’s stock performance and investor sentiment, especially if LY4066434 proves effective. Success in this trial could position Eli Lilly as a leader in KRAS-targeted therapies, potentially influencing the competitive landscape in oncology.
The study is currently ongoing, with further details available on the ClinicalTrials portal.
