Clinical Trial Summary

This is a Phase I/Ib study in which the safety of the combination therapy of RMC-4630 and LY3214996 in the treatment of KRAS mutant cancers will be studied.

Description:

This is a phase I / Ib study in which the safety of the combination therapy of RMC-4630 and LY3214996 in the treatment of KRAS mutant cancers colorectal cancer (CRC), non-small cell lung cancer (NSCLC) and pancreatic ductal adenocarcinoma will be studied.

The phase I dose-escalation study is designed to identify the recommended phase 2 dose (RP2D) of the combination regimen of RMC-4630 (SHP2-inhibitor) plus LY3214996 (ERK-inhibitor) in patients with KRASm CRC, NSCLC or PDAC.

The phase Ib expansion cohort is designed to further characterize the safety of the selected dose from the first stage of the study and to explore the clinical activity of RMC-4630 in combination with LY3214996 in patients with metastatic KRASm PDAC.

16. Patients with cardiac comorbidities (myocardial infarct within 6 months of study start, NYHA class = III, congestive heart failure or instable angina pectoris), uncontrolled hypertension (systolic blood pressure > 160 mm Hg and/or diastolic pressure > 90 mm Hg), prolonged QT interval(> 440 ms for men, > 460 ms for women) or patients who have had a stroke within 6 months prior to start study.

17. Other severe, acute, or chronic medical or psychiatric condition, laboratory abnormality active infections that may increase the risk associated with study participation or study drug administration or that may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for the study.

18. Patients with pulmonary embolisms or deep venous thrombosis (DVT) within 3 months prior to start

19. Known hypersensitivity to one of the study drugs or excipients.

20. Baseline diarrhea and/or any condition that would impair absorption of oral agents

21. Patient with a history or findings of central or branch retinal artery or venous occlusion with significant vision loss or other retinal diseases that cause current visual impairment or would likely cause visual impairment over the time period of the study, as assessed by an ophthalmologist.
