Official title
A Phase 1/2A, Open Label Dose Escalation and Expansion Study of Orally Administered CA-4948 as a Monotherapy in Patients With Acute Myelogenous Leukemia or Myelodysplastic Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a multicenter, open-label, Phase 1/2a dose escalation and expansion study of orally administered emavusertib (CA-4948) monotherapy in adult patients with AML or higher- risk Myelodysplastic Syndrome (hrMDS). Patients enrolling in the Phase 1 dose escalation of the study must meet one of the following criteria prior to consenting to the study: * Relapse/refractory (R/R) AML with FMS-like tyrosine kinase-3 (FLT3) mutations who have been previously treated with a FLT3 inhibitor * R/R AML with spliceosome mutations of splicing factor 3B subunit 1 (SF3B1) or U2AF1 * R/R hrMDS with spliceosome mutations of SF3B1 or U2 small nuclear RNA auxiliary factor 1 (U2AF1) * Number of pretreatments: 1 or 2 The Phase 2a Dose Expansion will be in 3 Cohorts of patients: 1. R/R AML with FLT3 mutations who have been previously treated with a FLT3 inhibitor; 2. R/R AML with spliceosome mutations of SF3B1 or U2AF1; and 3. R/R hrMDS (Revised International Prognostic Scoring System \[IPSS-R\] score \> 3.5) with spliceosome mutations of SF3B1 or U2AF1. All patients above have had ≤ 2 lines of prior systemic anticancer treatment. In previous versions of this protocol there was a Phase 1b portion of the study, in which patients with AML or hrMDS received CA-4948 in combination with venetoclax. This part of the study is no longer open for enrollment.
