Overview of Rapport Therapeutics

Company Background

Rapport Therapeutics is a clinical‐stage biotechnology company that has quickly emerged as a pioneer in the field of precision neuromedicine. Founded upon revolutionary discoveries in receptor biology, the company builds upon the foundational work of its scientific founders—most notably, discoveries pertaining to receptor‐associated proteins (RAPs) that modulate receptor expression and function within discrete regions of the brain. These early breakthroughs, initially spearheaded by renowned researchers such as Dr. David Bredt, have provided the scientific impetus for developing a novel technological platform that emphasizes precision over the traditionally broad‐spectrum approach of current therapies. This approach was validated through years of preclinical research and translational efforts, allowing the company to build a highly innovative discovery engine.

Since its inception, Rapport Therapeutics has attracted significant attention and investment from major financial backers such as Third Rock Ventures, ARCH Venture Partners, and Johnson & Johnson Innovation—signals that underscore both the market potential and the scientific rigor of its platform. The company not only successfully completed its initial public offering (IPO) and subsequently raised substantial capital to advance its clinical programmes, but has also steadily expanded its board, advisory network, and management team with leaders possessing extensive experience from industry titans including Pfizer, Janssen, Cubist Pharmaceuticals, and others. This strategic consolidation of talent and capital underpins Rapport Therapeutics’ ability to focus on a set of high-impact central nervous system (CNS) disorders, positioning it at the intersection of groundbreaking science and the urgent need for improved therapies.

Mission and Vision

At its core, the mission of Rapport Therapeutics is to develop transformational precision neuromedicines that address the significant unmet needs in CNS disorders.
