Endeavor Pharmaceuticals

Endeavor BioMedicines is a clinical-stage biotechnology company that launched in 2021, co-founded by CEO John Hood, Ph.D., and Chief Scientific Officer Miguel de los Rios, Ph.D. The company focuses on developing precision medicines for life-threatening diseases, particularly in oncology and fibrosis. Dr. Hood is a serial entrepreneur in the California life sciences community, having previously founded and led Impact Biomedicines, which was acquired by Celgene for $7 billion in 2018. His career includes co-discovering the now-approved drug fedratinib. Dr. de los Rios has over two decades of experience in the pharmaceutical industry, with a focus on developing novel therapeutics.

Endeavor's business model centers on acquiring and developing promising drug candidates that have originated elsewhere. The company's revenue generation is tied to the successful clinical development and eventual commercialization or partnership of its assets. It operates by raising capital through venture financing to fund its intensive research and development activities. Endeavor has successfully raised significant capital, including a $62 million Series A in 2021, a $101 million Series B in 2022, and an oversubscribed $132.5 million Series C in 2024, which is intended to fund operations through 2026.

The company's lead product candidate is ENV-101 (taladegib), an orally administered small molecule inhibitor of the Hedgehog signaling pathway. This pathway, when abnormally activated, is a key driver in the progression of fibrotic diseases and certain cancers. ENV-101 was initially developed by Eli Lilly and later acquired by Endeavor from Roche. The primary focus for ENV-101 is the treatment of idiopathic pulmonary fibrosis (IPF), a progressive and fatal lung disease with limited treatment options. Unlike current standards of care that only slow disease progression, clinical trial data for ENV-101 has shown the potential to not only improve lung function but also reverse key measures of lung fibrosis. The therapy has received Orphan Drug Designation in both the U.S. and the European Union for IPF.

Endeavor's pipeline also includes a second candidate, ENV-501, a next-generation HER3-targeting antibody-drug conjugate (ADC) for the treatment of solid tumors. This asset was acquired from Hummingbird Bioscience. ENV-501 is engineered to deliver a potent payload directly to cancer cells while minimizing off-target toxicity. By developing a portfolio of targeted therapies for diseases with high unmet medical needs, Endeavor aims to offer treatments that can potentially reverse the course of disease rather than just manage symptoms.
