Full Press Release Details
Announced positive data from the Phase 1 clinical trial of ELVN-001 in CML, reporting a cumulative MMR rate of 47% with 32% of patients achieving MMR by 24 weeks and demonstrating a favorable safety and tolerability profile across all dose levels
Strong balance sheet with $ 491 million in cash, cash equivalents and marketable securities, which is expected to provide cash runway into the first half of 2029
BOULDER, Colo. , Aug. 13, 2025 /PRNewswire/ -- Enliven Therapeutics, Inc. (Enliven or the Company) (Nasdaq: ELVN ), a clinical-stage biopharmaceutical company focused on the discovery and development of small molecule therapeutics, today reported financial results for the second quarter ended June 30, 2025 , and provided a business update, including highlights of pipeline progress.
"We made tremendous progress this quarter. Notably, we reported updated positive clinical data for ELVN-001, which continue to compare favorably to precedent Phase 1 trials of approved BCR::ABL1 TKIs despite being evaluated in a more heavily pre-treated patient population," said Sam Kintz , Co-founder and Chief Executive Officer of Enliven. "These results reinforce our belief that ELVN-001 could ultimately compete across all lines of CML therapy based on its differentiated efficacy, tolerability and convenience – attributes that position it to be a potential best-in-class therapy for people living with CML. Building on the strength of these findings, we expect to initiate our first Phase 3 pivotal trial in 2026 and remain confident in ELVN-001's potential within the CML treatment landscape. We also strengthened our balance sheet through our recent public offering, which generated gross proceeds of approximately $230 million and extended our cash runway into the first half of 2029."
Pipeline Updates
ELVN-001 is a potent, highly selective, small molecule kinase inhibitor designed to specifically target the BCR::ABL gene fusion, the oncogenic driver for patients with chronic myeloid leukemia (CML).
• In June 2025 , the Company announced positive updated data from the ongoing ENABLE Phase 1 clinical trial evaluating ELVN-001 in patients with previously treated CML ( NCT05304377 ) in an oral presentation at the European Hematology Association (EHA) Congress. As of the April 28, 2025 , cutoff date, 25 of 53 (47%) evaluable patients were in major molecular response (MMR) by 24 weeks, with 13 of 41 (32%) achieving and 12 of 12 (100%) maintaining MMR. ELVN-001 remains well-tolerated across all evaluated doses.
• These data continued to compare favorably to precedent Phase 1 MMRs for approved BCR::ABL1 tyrosine kinase inhibitors (TKIs), particularly given the more heavily pretreated patient population in the ELVN-001 clinical trial. Specifically, the achieved MMR rate by 24 weeks of 32% compares favorably with historical data from less heavily pretreated patients receiving asciminib, which showed achieved MMR rates of 24% in the Phase 1 trial and 25% in the ASCEMBL Phase 3 trial.
• The Company plans to initiate a Phase 3 pivotal trial in 2026.
• As of the April 28, 2025 , cutoff date, 25 of 53 (47%) evaluable patients were in major molecular response (MMR) by 24 weeks, with 13 of 41 (32%) achieving and 12 of 12 (100%) maintaining MMR.
• ELVN-001 remains well-tolerated across all evaluated doses.
• Specifically, the achieved MMR rate by 24 weeks of 32% compares favorably with historical data from less heavily pretreated patients receiving asciminib, which showed achieved MMR rates of 24% in the Phase 1 trial and 25% in the ASCEMBL Phase 3 trial.
Second Quarter 2025 Financial Results
• Cash Position: As of June 30, 2025 , the Company had cash, cash equivalents and marketable securities totaling $490.5 million , which is expected to provide cash runway into the first half of 2029.
