pre Assignment Details
Accrual process was slow due to various reasons including multiple screen failures for reasons including inability to perform integral biomarker testing for TP53 mutation status due to \<5% plasma cells in bone marrow biopsy at screening, TP53 mutation detected, not having measurable disease, and low creatinine clearance below eligibility threshold. 35 patients were consented, of those16 patients were eligible and dosed.
recruitment Details
Study opened to accrual on 10/2017 at 6 sites across ETCTN network (MD Anderson, UC Davis, UT San Antonio, UT Austin, University of Utah, Weill Cornell). Study closed to accrual 07/2024 due to uncertain development plan of MDM2 inhibitors in myeloma and slow accrual after discussion with NCI CTEP leadership and study industry collaborator, Kartos Therapeutics.
