ENB Therapeutics

ENB Therapeutics is a clinical-stage biopharmaceutical company focused on addressing the significant challenge of drug resistance in cancer therapy. The firm was co-founded by Sumant Ramachandra, a seasoned pharmaceutical executive with experience at companies like Pfizer and Baxter, and Zachary Hornby. Ramachandra's background in drug development and corporate strategy, combined with Hornby's expertise in business development and operations, provided the foundational leadership for the company's mission.

The company's core focus is the development of treatments that can overcome resistance to immunotherapy, a problem observed in a substantial portion of cancer patients. ENB Therapeutics operates within the oncology market, specifically targeting the multi-billion dollar immunotherapy sector. Its business model centers on the research, clinical development, and eventual commercialization of proprietary drug candidates. Revenue generation is anticipated through partnerships, licensing agreements with larger pharmaceutical companies, and ultimately, sales of its approved therapies.

ENB's lead product candidate is ENB-001, a first-in-class small molecule inhibitor of the endothelin B receptor (ETBR). This receptor is often overexpressed in various tumor types, contributing to immune suppression and limiting the effectiveness of immunotherapies like PD-1 inhibitors. By blocking the ETBR pathway, ENB-001 is designed to increase the infiltration of T-cells into the tumor microenvironment, thereby making tumors more susceptible to attack by the immune system. The company has advanced ENB-001 into a Phase 1/2 clinical trial, investigating its safety and efficacy in combination with Merck's KEYTRUDA® (pembrolizumab) for patients with platinum-resistant ovarian cancer. This product received Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) in 2016 for melanoma, a status that provides market exclusivity and other development incentives. The company is also developing a companion diagnostic to identify patients whose tumors overexpress the ETBR pathway, allowing for a more targeted and potentially more effective treatment approach across various cancer types.
