About ELVN-001

ELVN-001 is a potent, highly selective, small molecule kinase inhibitor designed to specifically target the breakpoint cluster region – Abelson (“BCR-ABL”) gene fusion, the oncogenic driver for patients with chronic myeloid leukemia (“CML”). It targets the ATP-binding site of the ABL1 kinase domain and binds to a unique P-loop “folded-in” active conformation of ABL1, creating a narrow selectivity tunnel. 

As a highly selective ATP-competitive inhibitor, ELVN-001 is differentiated from other ATP-competitive inhibitors in that it avoids off-target activity that may cause adverse events. With this potential additional safety margin, ELVN-001 may be optimally dosed to drive better efficacy. Additionally, ELVN-001 potentially represents a complementary option to allosteric BCR-ABL inhibitors (e.g., asciminib) due to its distinct mechanism of action and high selectivity which may play an increasingly important role in the standard of care for CML. Specifically, ELVN-001 was designed to have activity against emerging mutations known to confer resistance to allosteric TKIs, including asciminib. ELVN-001 was also designed to be a more attractive option for patients with comorbidities, on concomitant medications or desiring more freedom from stringent administration requirements. 

ELVN-001 is currently being evaluated in the Phase 1 ENABLE clinical trial in heavily pretreated patients with CML, and we plan to initiate ENABLE-2, a 2L+ Phase 3 pivotal trial in the second half of 2026. The most recent data is available on the Program Presentation & Publications section of the website.
