Entact Bio is developing a novel class of precision medicines that enhance the function of beneficial proteins. Launched by a founding team deeply rooted in deubiquitylase (DUB) biochemistry, chemical biology, disease biology, and small-molecule drug development, Entact has built its proprietary Encompass™ platform to create enhancement-targeting chimeric (ENTAC™) medicines. ENTACs leverage the natural ability of DUBs to regulate and enhance protein function. By harnessing the power of DUBs, Entact is expanding the universe of treatable diseases and creating new options for patients who are underserved by current therapeutic modalities.

NextCure is a clinical-stage biopharmaceutical company committed to discovering and developing novel, first-in-class immunomedicines to treat cancer and other immune-related diseases by restoring normal immune function. We view the immune system holistically and, rather than target one specific immune cell type, we focus on understanding biological pathways, the interactions of cells and the role each interaction plays in an immune response. Through our proprietary Functional, Integrated, NextCure Discovery in Immuno-Oncology, or FIND-IO, platform, we study various immune cells to discover and understand targets and structural components of immune cells and their functional impact in order to develop immunomedicines. We are focused on patients who do not respond to current therapies, patients whose cancer progresses despite treatment and patients with cancer types not adequately addressed by available therapies.

Cybrexa is a clinical-stage oncology biotechnology company developing novel antigen-independent peptide drug conjugates (ADCs) aimed at combatting a range of cancer types, including ovarian, breast and non-small cell lung cancer. With the potential to disrupt the standard of care, the Cybrexa alphalex™ technology is a novel antigen-independent peptide drug conjugate (PDC) platform that enables targeted delivery of highly potent anticancer treatments and aims to revolutionize the standard of care in oncology. The platform consists of a pHLIP® peptide, linker, and small molecule anti-cancer agent. pHLIP® peptides are a family of pH-Low Insertion Peptides that target acidic cell surfaces. pHLIP® was developed at Yale University and the University of Rhode Island, and is exclusively licensed to pHLIP, Inc. alphalex™ represents the disruptive next generation in tumor targeting. Early clinical trials of the company’s lead candidate, CBX-12, demonstrate robust efficacy signals and tolerability in patients with metastatic cancer. As a privately held company, Cybrexa is led by a management team experienced at building life science companies and driven by scientists with an expertise in drug development and oncology.
