ELVN-001’s Safety Profile Consistent with High Selectivity for ABL1
| |
• |
|
ELVN-001 was generally well-tolerated, consistent with its high selectivity. |
| |
• |
|
6% of patients discontinued due to adverse events. |
| |
• |
|
The majority of treatment-emergent adverse events (TEAEs) were Grade 1 or 2. |
| |
• |
|
Grade ≥3 TEAEs were reported in 53/158 (34%) patients overall; with thrombocytopenia (6%), neutropenia (6%) and lipase elevation (6%) as the most common. |
| |
• |
|
At the biologically optimal dose of 80 mg QD (n=62), Grade ≥3 TEAEs were reported in 15/62 (24%) patients, with thrombocytopenia (6%) being the only Grade ≥3 TEAE reported in >5% of patients. |
Key Outcomes from the End-of-Phase 1 Meeting with the FDA
| |
• |
|
80 mg QD selected as the recommended dose for Phase 3 ENABLE-2 trial. |
| |
• |
|
ENABLE-2 is expected to enroll patients with CML previously treated with one or more TKIs, and to be randomized to receive either ELVN-001 or physician’s choice of an ATP-competitive TKI. |
| |
• |
|
Additional details of the Phase 3 trial design are expected to be finalized following further discussions with the FDA, including at a planned End-of-Phase 2 meeting anticipated in the third quarter of 2026. |
Cautionary Note Regarding Forward-Looking Statements
This Current Report on Form 8-K contains forward-looking statements (including within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended) concerning the Company and other matters that involve substantial risks and uncertainties. These statements may discuss goals, intentions and expectations as to future plans, trends, events, results of operations and financial condition, or otherwise, based on current beliefs of the management of the Company, as well as assumptions made by, and information currently available to, management of the Company. Forward-looking statements generally include statements that are predictive in nature and depend upon or refer to future events or conditions, and include words such as “may,” “will,” “should,” “would,” “expect,” “anticipate,” “plan,” “likely,” “believe,” “estimate,” “project,” “intend,” and other similar expressions or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Statements that are not historical facts are forward-looking statements. Forward-looking statements in this Current Report on Form 8-K include, but are not limited to: statements regarding the potential profile, activity, selectivity, safety, tolerability, efficacy, differentiated attributes, therapeutic benefit and potential best-in-class or complementary profile of ELVN-001 to allosteric inhibitors; the interpretation of data from the ongoing ENABLE trial, including MMR rate, safety and tolerability data; comparisons to historical or precedent clinical trial results; the timing, content and availability of additional clinical data and presentation materials; the continued conduct, design, objectives, endpoints, dose selection and future clinical evaluation of ELVN-001, including the planned ENABLE-2 Phase 3 trial, the potential timing of initiation of ENABLE-2, the potential timing and outcome of further FDA discussions and the finalization of additional Phase 3 trial design details; and statements by the Company’s Chief Medical Officer and Dennis Kim, M.D., Professor of Medicine, Department of Medical Oncology and Hematology at the Princess Margaret Cancer Centre, Canada. Forward-looking statements are based on current beliefs and assumptions that are subject to risks and uncertainties and are not guarantees of future performance. Actual results could differ materially from those contained in any forward-looking statement as a result of various risks and uncertainties, including, without limitation: the potential for interim, topline and preliminary results from the Company’s clinical trials to materially change as additional patient data become available or following more comprehensive review; the potential for results from the ongoing or any future clinical trial of ELVN-001 to differ from the results of earlier trials of ELVN-001; ELVN-001 failing to demonstrate sufficient safety, efficacy, tolerability, durability, differentiated attributes or therapeutic benefit in current or future clinical trials; risks associated with unexpected events during the remainder of the ENABLE trial, including serious adverse events, toxicities, dose reductions, discontinuations or other undesirable side effects;
