Announced positive proof of concept data from Phase 1 clinical trial of ELVN-001 in CML, achieving an initial cumulative MMR rate of 44% (7/16) by 12 weeks in response-evaluable patients
Strong balance sheet with $321 million in cash, cash equivalents and marketable securities, which is expected to provide cash runway into late 2026
BOULDER, Colo., May 14, 2024 (GLOBE NEWSWIRE) -- 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 first quarter ended March 31, 2024, and provided a business update, including highlights of pipeline progress.
"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, Enliven's 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."
Corporate Updates
- Entered into a securities purchase agreement for a private investment in public equity (PIPE) financing resulting in gross proceeds of $90 million. The financing, from both new and existing investors, is expected to extend the Company's cash runway into late 2026 and through multiple key milestones for ELVN-001 and ELVN-002.
- Appointed to the Board of Directors, Lori Kunkel, MD, an accomplished industry executive and board member with a track record of success in corporate strategy, clinical development and commercialization.
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).
- Announced positive proof of concept data from the Phase 1 clinical trial evaluating ELVN-001 in patients with CML who are relapsed, refractory or intolerant to available tyrosine kinase inhibitors (TKIs).
- As of the cutoff date of March 18, 2024, 44% (7/16) of response-evaluable patients achieved a cumulative major molecular response (MMR) rate by week 12, and patients with prior exposure to asciminib and/or who were TKI-resistant also demonstrated responses, with a 44% and 40% cumulative MMR rate, respectively. Among response-evaluable patients, all had improved or stable BCR::ABL1 transcript levels by 12 weeks. ELVN-001 was well tolerated with no Grade 3 or higher non-hematologic treatment-related adverse events and no dose reductions reported.
- These data compare favorably to precedent Phase 1 cumulative MMR rates for approved BCR::ABL1 TKIs, particularly given the more heavily pre-treated patient population. Further details can be found here.
- Phase 1b data is expected in 2025 and is expected to include between 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.
- Following U.S. Food and Drug Administration approval of its Investigational New Drug application, the Company activated the first site to evaluate ELVN-002 in combination with trastuzumab +/- chemotherapeutic agents in HER2+ metastatic breast cancer (MBC) and colorectal cancer (CRC). First patient dosing for the combination trial is expected in Q2 2024.
- The combination trial in patients with HER2+ cancers is supported by the initial data from the ongoing monotherapy trial, which includes:
- Investigator reported responses (including unconfirmed) in both HER2+ and HER2 mutant tumors, including in patients who have progressed on Enhertu and patients with brain metastases, at doses that have been well tolerated.
- Importantly, at the clinically predicted optimal monotherapy dose, ELVN-002 had >10x target coverage based on pharmacokinetics in cancer patients and preclinical HER2+ efficacy compared to tucatinib.
- 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.
First Quarter 2024 Financial Results
- Cash Position: As of March 31, 2024, the Company had cash, cash equivalents and marketable securities totaling $320.5 million, which is expected to provide cash runway into late 2026.
- Research and development (R&D) expenses: R&D expenses were $20.0 million for the first quarter of 2024, compared to $11.9 million for the first quarter of 2023.
- General and administrative (G&A) expenses: G&A expenses for the first quarter of 2024 were $6.0 million, compared to $4.5 million for the first quarter of 2023.

Head-to-Head Comparisons
The Company has not performed any head-to-head trials for ELVN-001. As a result, the data referenced in this press release is derived from different clinical trials at different points in time, with differences in trial design and patient populations. As a result, conclusions from cross-trial comparisons cannot be made.
