A Phase 1a/1b Open-Label Study Evaluating the Safety, Tolerability, Pharmacokinetics, and Efficacy of BBO-11818 in Subjects with Advanced KRAS Mutant Cancers

The purpose of this study is to find the best dose of the study drug, BBO-11818, when used alone (single therapy) and in combination with other standard of care treatments, and to see what effects, good or bad, the study drug has on participants. While the standard of care treatments, pembrolizumab, pemetrexed, cisplatin, carboplatin, and cetuximab are FDA-approved individually, the combination of BBO-11818 with these treatments is considered experimental. The study drug, BBO-11818, has not been approved by the U.S. Food and Drug Administration (FDA). This is the first time that BBO- 11818 has been tested in humans.
