Title:

Phase 1/2a study of the IRAK4 inhibitor CA-4948 as monotherapy or in combination with azacitidine or venetoclax in patients with relapsed/refractory (R/R) acute myeloid leukemia or lyelodysplastic syndrome.

Excerpt:
This is an open-label, phase 1/2a dose escalation and cohort expansion trial (NCT04278768). In phase 1 Dose Escalation, patients with R/R AML or HR-MDS are treated with CA-4948 monotherapy...Of 43 patients starting before Sept 30th, 2021, 14 had SF3B1, U2AF1 or FLT3 mutations and demonstrated more promising efficacy...CA-4948 is well tolerated and effective in heavily pretreated AML and HR-MDS patients, especially in those with U2AF1/SF3B1/FLT3 mutations.

Title:

TAKEAIM LEUKEMIA- A PHASE 1/2A STUDY OF THE IRAK4 INHIBITOR EMAVUSERTIB (CA-4948) AS MONOTHERAPY OR IN COMBINATION WITH AZACITIDINE OR VENETOCLAX IN RELAPSED/REFRACTORY AML OR MDS

Published date:
05/12/2022
Excerpt:
In the 7 spliceosome-mutated HR-MDS patients, 57% reached marrow CR, including 1 with RBC transfusion independence and 1 proceeding to HSCT. One of the three FLT3-mutated AML reached CR, and 2 became FLT3-negative. Among the 29 patients without SF3B1/U2AF1/FLT3 mutations, 1 reached CR and 2 PR. Phase 1b and Phase 2a are ongoing. RNA-seq on selected samples showed decrease in relative expression of IRAK4-long isoforms with response to emavusertib. Emavusertib is well tolerated and effective in heavily pretreated AML and HR-MDS patients, especially in those with U2AF1/SF3B1/FLT3 mutations.
