Official title
MasterKey-01: A Phase 1/2, Open-label, Two-part, Multicenter Study to Assess the Safety, Tolerability, Pharmacokinetics & Antitumor Activity of BDTX-189, an Inhibitor of Allosteric ErbB Mutations, in Patients w/ Advanced Solid Malignancies
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This was a clinical study with an orally administered drug, BDTX-189 in participants with advanced solid tumors that had select mutations or alterations in human epidermal growth factor receptor 2 (HER2/ErbB2) genes or epidermal growth factor receptor (EGFR/ErbB1). The main goals of this study were to: * Find the recommended dose of BDTX-189 that can be given safely to participants * Learn more about the side effects of BDTX-189 * Learn what the body does to BDTX-189 after it has been taken (pharmacokinetics or PK) * Determine the preliminary antitumor activity of BDTX-189 in participants with select allosteric ErbB gene mutations
