Company Description
Enliven Therapeutics, Inc. (Nasdaq: ELVN) is a clinical-stage biopharmaceutical company based in Boulder, Colorado. According to the company, Enliven is focused on the discovery and development of small molecule therapeutics with a precision oncology approach that aims to help people live longer and live better. Its discovery process combines insights into clinically validated biological targets with differentiated chemistry to design potentially first-in-class or best-in-class therapies.
Business focus and therapeutic area
Enliven operates in the pharmaceutical preparation manufacturing industry within the broader manufacturing sector. The company describes its strategy as addressing existing and emerging unmet medical needs using precision oncology to improve survival and overall well-being. Its programs are centered on small molecule kinase inhibitors designed against specific oncogenic drivers in cancer.
Key clinical program: ELVN-001 in chronic myeloid leukemia
The company’s lead product candidate is ELVN-001, a potent, highly selective small molecule kinase inhibitor designed to specifically target the BCR::ABL gene fusion, which Enliven describes as the oncogenic driver for patients with chronic myeloid leukemia (CML). ELVN-001 is characterized by the company as a selective active-site tyrosine kinase inhibitor (TKI) with a mechanism of action that is complementary to allosteric BCR::ABL1 inhibitors.
Enliven states that ELVN-001 was designed to have activity against the T315I mutation, the most common BCR::ABL1 mutation, and mutations known to confer resistance to allosteric BCR::ABL1 inhibitors. The company has also highlighted data in CML patients with atypical BCR::ABL1 fusion transcripts, including e13a3, e19a2 and e1a3, a subgroup that it notes represents a growing unmet need and can be resistant to certain TKIs.
ENABLE Phase 1 program
Enliven is conducting the ENABLE study (NCT05304377), a Phase 1 clinical trial of ELVN-001 in patients with previously treated CML. The trial includes dose escalation and expansion components (Phase 1a/1b) and is designed to evaluate safety and tolerability and to determine a recommended dose for further clinical evaluation in patients with CML with and without T315I mutations that are relapsed, refractory or intolerant to TKIs. Secondary endpoints include pharmacokinetics, major molecular response (MMR) assessed by central quantitative reverse transcriptase polymerase chain reaction, duration of MMR, BCR::ABL1 transcript levels and complete hematologic response.
In reported Phase 1 and Phase 1b data from ENABLE, Enliven has described encouraging clinical activity and a favorable safety and tolerability profile across evaluated doses of ELVN-001. In heavily pretreated CML patients, including those who had received multiple prior TKIs such as asciminib and ponatinib, the company has reported cumulative MMR rates by 24 weeks and deep molecular responses, while noting that all evaluable patients who were in MMR at enrollment maintained or deepened their response in the Phase 1b cohorts. The company also reported that no maximum tolerated dose had been identified within the tested range and that no new safety signals had been observed in the Phase 1b cohorts.
Clinical development trajectory
Enliven has outlined a development path for ELVN-001 that includes additional Phase 1 data presentations and regulatory interactions to support dose selection and the design of a planned Phase 3 pivotal trial in CML. The company has stated that it is preparing for the initiation of a Phase 3 trial (ENABLE-2) and has referenced interest from clinical sites in multiple geographies. Enliven has also reported that ELVN-001 data have been featured in oral and poster presentations at major hematology and oncology meetings, including the European Hematology Association (EHA), the Society of Hematologic Oncology (SOHO), the European Society of Hematology International Chronic Myeloid Leukemia Foundation (ESH-iCMLf), the German, Austrian and Swiss Societies for Hematology and Medical Oncology (DGHO), the Japanese Society of Hematology (JSH), and the American Society of Hematology (ASH).
Precision oncology and discovery approach
Across its communications, Enliven emphasizes a precision oncology approach that seeks to match small molecule therapeutics to well-characterized biological drivers of disease. The company describes its discovery engine as combining deep insights into clinically validated targets with differentiated chemistry to design therapies that it characterizes as potentially first-in-class or best-in-class. This approach is intended to address both existing and emerging unmet needs in oncology, including patient subgroups such as those with atypical fusion transcripts or resistance-conferring mutations.
Corporate and capital markets profile
Enliven’s common stock trades on the Nasdaq under the ticker symbol ELVN. The company has reported completing underwritten public offerings of common stock and pre-funded warrants, with gross proceeds described in its press releases, and has indicated that these financings contribute to a cash runway it expects to extend into a future multi-year period. Enliven has also disclosed the adoption of a 2025 Inducement Equity Incentive Plan and the grant of inducement stock options to its President and Chief Executive Officer in connection with his appointment, as described in its Form 8-K filing.
Leadership and governance developments
Through SEC filings and press releases, Enliven has reported leadership changes aligned with its transition toward late-stage development and potential commercialization. An 8-K filing describes the appointment of Richard Fair as President and Chief Executive Officer and a member of the board of directors, and the transition of co-founder Samuel Kintz to the role of Head of Pipeline. The company has also announced the appointment of Scott Garland to its board of directors as it prepares for the next phase of development and commercialization of ELVN-001.
Regulatory disclosures and financial reporting
Enliven files periodic and current reports with the U.S. Securities and Exchange Commission (SEC), including Form 10-K annual reports, Form 10-Q quarterly reports, and Form 8-K current reports describing material events such as clinical updates, financial results, leadership changes and equity plans. In its quarterly press releases, the company provides selected condensed consolidated financial information and discusses research and development and general and administrative expenses, net loss, cash, cash equivalents and marketable securities, and other balance sheet items.
Position within the biopharmaceutical landscape
Within the biopharmaceutical sector, Enliven characterizes itself as a company focused on precision oncology and small molecule kinase inhibitors. Its lead program, ELVN-001, targets a well-established oncogenic driver in CML and is being evaluated in heavily pretreated patient populations, including those with resistance-associated mutations and atypical fusion transcripts. The company’s communications emphasize the potential for ELVN-001 to address unmet needs in CML and its intention to advance the program into pivotal-stage development.
