Future Outlook

The company expects its cash runway to extend into late 2026. Phase 1b data for ELVN-001 is expected in 2025. First patient dosing for the ELVN-002 combination trial is expected in Q2 2024. Phase 1 monotherapy data, Phase 1a/b Herceptin combination data in HER2+ CRC, and initial Phase 1a combination data in HER2+ MBC are expected in 2025.

Management Comments

• The first quarter of 2024 was a pivotal quarter for Enliven.
• We released positive proof of concept data from our Phase 1 clinical trial of ELVN-001, which was a significant milestone for the Company said Sam Kintz, MBA, Enlivens Co-founder and Chief Executive Officer.
• We are thrilled by the initial ELVN-001 data, particularly the tolerability profile and evidence of activity in heavily pre-treated patients, including in patients with asciminib-resistant chronic myeloid leukemia.
• We also continued to advance our trials of ELVN-002, including the activation of the first site to evaluate ELVN-002 in combination with trastuzumab in patients with HER2+ cancers, which we believe is an area of significant unmet need for patients.
• Additionally, we extended our cash runway into late 2026 thanks to the support of new and existing investors.

Industry Context

The announcement highlights Enliven's progress in the competitive oncology space, particularly in developing targeted therapies for CML and HER2+ cancers. The positive data for ELVN-001 positions it as a potential competitor to existing tyrosine kinase inhibitors. The focus on combination therapies for HER2+ cancers aligns with current trends in oncology treatment.

Comparison to Industry Standards

• The 44% MMR rate for ELVN-001 in heavily pre-treated CML patients compares favorably to precedent Phase 1 cumulative MMR rates for approved BCR::ABL1 TKIs, though direct comparisons are limited due to differences in trial design and patient populations.
• While specific head-to-head trials are not available, the data suggests ELVN-001 could be a best-in-class treatment option.
• The development of ELVN-002 as a HER2 inhibitor with CNS penetration and activity against various HER2 mutations positions it against competitors like tucatinib, with the company claiming >10x target coverage based on pharmacokinetics in cancer patients and preclinical HER2+ efficacy compared to tucatinib.

Management Changes

Stakeholder Impact

• Shareholders benefit from the positive clinical data and extended cash runway.
• Employees are likely to be positively impacted by the company's progress and financial stability.
• Patients with CML and HER2+ cancers may benefit from the development of new treatment options.
• Investors are likely to be encouraged by the company's progress and future prospects.

Next Steps

• First patient dosing for the ELVN-002 combination trial is expected in Q2 2024.
