Enliven (NASDAQ: ELVN) shares updated ELVN-001 CML data and FDA Phase 3 alignment
Rhea-AI Filing Summary
Enliven Therapeutics announced updated positive Phase 1 data for its CML drug candidate ELVN-001 and reported key outcomes from an End-of-Phase 1 meeting with the FDA. In Phase 1b, overall major molecular response (MMR) reached 54% in evaluable patients and 61% in the 80 mg once-daily cohort by week 24, with 100% of patients who achieved MMR maintaining it. Response rates by 24 weeks were higher in patients treated earlier in their TKI sequence, including those previously on asciminib. The safety profile was described as favorable and consistent with ELVN-001’s high selectivity, based on 161 enrolled patients and a median treatment duration of 35 weeks. Enliven and the FDA reached alignment on 80 mg once daily as the recommended Phase 3 dose and on a second-line-or-later patient population for the planned ENABLE-2 pivotal trial, which the company expects to initiate in the second half of the year.

Insights
Phase 1 CML data look encouraging, with FDA alignment on Phase 3 design.
Enliven reported updated Phase 1 ENABLE results for ELVN-001 in previously treated CML. Overall MMR was 54% in Phase 1b and 61% in the 80 mg cohort by 24 weeks, with all patients who reached MMR maintaining it at that timepoint.
The program now has safety and tolerability data from 161 patients with a median treatment duration of 35 weeks, supporting use of 80 mg once daily. The data include responses across multiple prior TKI lines and in patients previously treated with asciminib.
Importantly, Enliven and the FDA agreed on 80 mg QD and a 2L+ population for the planned ENABLE-2 Phase 3 trial, expected to start in the second half of the year. Future disclosures from ENABLE and ENABLE-2 will be central to understanding ELVN-001’s potential role in CML treatment.
