简要总结
This is a multicenter, open label, first in human (FIH) study of inlexisertib as monotherapy, and in combination with trametinib, binimetinib, or sotorasib in participants with advanced or metastatic solid tumors with RAS/MAPK pathway mutation.

- •Any other clinically significant comorbidities.
- •For participants receiving inlexisertib and trametinib combination or inlexisertib and binimetinib combination: previous treatment with trametinib or binimetinib that resulted in treatment discontinuation due to intolerability as a result of an adverse event (AE) that was considered related to trametinib or binimetinib.
- •For participants receiving inlexisertib and sotorasib combination in Dose Escalation Part 1: previous treatment with sotorasib that resulted in treatment discontinuation due to intolerability as a result of an adverse event (AE) that was considered related to sotorasib.
- •For participants receiving inlexisertib and sotorasib combination: Use of proton pump inhibitors (PPIs) and H2 receptor antagonists that cannot be discontinued 3 days prior to the start of study drug administration.
