Enliven Therapeutics Reports Second Quarter Financial Results and Provides a Business Update

Enliven Therapeutics, Inc. (Enliven or the Company) (Nasdaq: ELVN), a clinical-stage precision oncology company focused on the discovery and development of next-generation small molecule kinase inhibitors, today reported financial results for the second quarter ended June 30, 2024, and provided a business update, including highlights of pipeline progress.

“The second quarter of 2024 marked another period of significant progress for both of our parallel lead programs, ELVN-001 and ELVN-002,” said Sam Kintz, MBA, Enliven’s Co-founder and Chief Executive Officer. “We began dosing patients in the Phase 1b arm for ELVN-001 and in two combination trials for ELVN-002. Additionally, an abstract updating the data from the ongoing Phase 1a trial for ELVN-001 has been accepted for presentation at the upcoming ESH-iCMLf Conference in September.”

Pipeline Updates

ELVN-001 is a potent, highly selective, potentially best-in-class small molecule kinase inhibitor designed to specifically target the BCR-ABL gene fusion, the oncogenic driver for patients with chronic myeloid leukemia (CML).

• The first patient was dosed in the Phase 1b arm of the clinical trial evaluating ELVN-001 in patients with CML that is relapsed, refractory or intolerant to available tyrosine kinase inhibitors (TKIs).
• The Company announced positive proof of concept data from the Phase 1a clinical trial in April of this year, and an abstract with updated Phase 1a data was accepted for presentation at the European Society of Hematology International CML Foundation 26th Annual John Goldman Conference on CML taking place September 27-29 in Prague, Czech Republic.
• Additional Phase 1 data is expected in 2025 and is planned to include approximately 60-100 patients across various lines of therapy with significant follow-up.

ELVN-002 is a potent, highly selective, central nervous system penetrant and irreversible HER2 inhibitor with activity against wild type HER2 and various HER2 mutations.

• The first patient was dosed in the Phase 1a trial evaluating ELVN-002 in combination with trastuzumab +/- chemotherapeutic agents in patients with HER2+ metastatic breast cancer (MBC) and colorectal cancer (CRC).
• Additionally, the first patient with HER2+ MBC was dosed in the exploratory Phase 1a arm evaluating ELVN-002 in combination with ado-trastuzumab emtansine (Kadcyla®), an approved HER2 antibody drug conjugate.
• Phase 1 monotherapy data and initial Phase 1a combination data are expected in 2025.

Second Quarter 2024 Financial Results

• Cash Position: As of June 30, 2024, the Company had cash, cash equivalents and marketable securities totaling $312.4 million, which is expected to provide cash runway into late 2026.
