Management Comments

• 'We are very pleased with the continued progress of ELVN-001 and the data that was just released in the EHA abstract,' said Sam Kintz, Co-founder and Chief Executive Officer of Enliven.
• Management believes the efficacy, safety, and tolerability data of ELVN-001 consistently compare favorably to the approved BCR::ABL inhibitors.

Industry Context

Enliven Therapeutics is developing small molecule therapeutics in the competitive biopharmaceutical industry, focusing on precision oncology. The company's lead candidate, ELVN-001, targets CML, while ELVN-002 targets HER2-positive cancers. The company's decision to focus on ELVN-001 and seek strategic alternatives for ELVN-002 reflects a strategic prioritization of resources in a challenging funding environment for biotech companies.

Comparison to Industry Standards

• The reported MMR rate of 44% for ELVN-001 in heavily pre-treated CML patients compares favorably to precedent Phase 1 trials of approved BCR::ABL1 tyrosine kinase inhibitors (TKIs).
• However, direct comparisons are limited due to differences in trial design and patient populations.
• Companies like Novartis (Tasigna), Bristol Myers Squibb (Sprycel), and Pfizer (Bosulif) have established TKIs in the CML space, setting a high bar for efficacy and safety.
• Enliven's $290 million cash position provides a competitive advantage, allowing for continued clinical development and strategic flexibility.

Stakeholder Impact

• Shareholders may react positively to the promising clinical data for ELVN-001 and the extended cash runway.
• Employees may experience uncertainty due to the planned discontinuation of ELVN-002 development.
• Patients with CML may benefit from the potential advancement of ELVN-001 as a treatment option.
• The decision to discontinue ELVN-002 may impact suppliers and partners involved in that program.

Next Steps

• Enliven will present updated data from the Phase 1 ENABLE clinical trial of ELVN-001 at the EHA 2025 Congress in June.
• Enliven will host a webcast and conference call on June 13, 2025, to discuss the updated data.
• The company plans to explore strategic alternatives for the ELVN-002 program.
• The company is preparing for the potential start of a pivotal trial for ELVN-001 in 2026.
