ELVN-001 for the Treatment of Chronic Myeloid Leukemia With and Without T315I Mutation in Japanese Participants

This first-in-human trial with ELVN-001 is a dose escalation study with the primary purpose to identify the recommended dose(s) for expansion (RDEs) of single agent ELVN-001 in chronic phase CML with or without T315I mutations. The safety, tolerability and pharmacokinetic profile of ELVN-001 will be assessed together with an evaluation of changes in BCR-ABL1 transcript. An understanding of the safety profile, PK and preliminary evidence of anti-CML activity will be used to inform future development of ELVN-001 in adults with CML. By virtue of its predicted pharmacological profile ELVN-001 has the potential to be tolerable and achieve a deep molecular response in patients with CML with or without T315I mutations who have failed, or are intolerant to, or not a candidate for, at least 2 prior TKIs.

Inclusion criteria

• BCR::ABL1 positive CP-CML that has failed, or the patient is intolerant to, or not a candidate for, at least 2 prior TKIs.
• ECOG performance status of 0 to 2.
• The patient was born in Japan and both parents and grandparents are Japanese.
• Adequate hematologic, hepatic and renal function.
• Prior bone marrow transplant allowed if ≥ 6 months prior to the first dose of ELVN-001.

Exclusion criteria

• Treatment with anti-cancer or anti-CML therapy within 7 days or 5 half-lives, whichever is longer.
• History of acute tyrosine kinase inhibitor (TKI)-related pancreatitis within 6 months of study entry. Active chronic pancreatitis, or pancreatic disease due to any cause.
• QTc >470 ms.
