KT-413

KT-413 achieves concurrent degradation of these proteins by functioning as both a heterobifunctional degrader and a molecular glue. Based on the demonstrated activity and safety of KT-413 in preclinical studies, a phase 1 clinical trial in B-cell lymphomas, including MYD88 mutant ABC DLBCL, is currently underway.

Initial clinical data with KT-413 demonstrate degradation of IRAK4 and Ikaros/Aiolos in PBMC and tumor. It is anticipated that higher doses will achieve the predicted degradation profile in tumors that may confer clinical benefit in MYD88-mutant patients. Dose escalation is ongoing, and analyses from additional patients will be presented at the meeting.

Furthermore, based on new genetic classifications, co-mutations in MYD88 and CD79 (C5 and MCD subgroups) are associated with an inferior survival after standard R-CHOP. Enrollment in the Phase 1a portion of the KT413-DL-101 study is ongoing. NCT05233033.

Background: Based on new genetic classifications, co-mutations in MYD88 and CD79B (C5 and MCD subgroups) are associated with an inferior survival after standard R-CHOP. Preclinical studies highlight the potential of IRAKIMiDs as a therapeutic approach for the treatment of MYD88MT DLBCL. KTX-582 demonstrates preferential activity in MYD88MT ABC-DLBCL. Single agent venetoclax demonstrated varying potency in ABC-DLBCL cell lines, irrespective of MYD88 mutational status.
