Founded in 2015 by a group of eminent scientists including David Elliot Shaw, Matthew P. Jacobson, Dorothee Kern, Mark Murcko, Alexis Borisy, and Jakob Loven, Relay Therapeutics was established with the vision to push the boundaries of drug discovery through technology integration. Beginning as a company with a focus on merging disparate scientific disciplines, Relay has evolved by continuously expanding its suite of computational and experimental capabilities. Over the years, notable strategic investments such as the acquisition of ZebiAI have further bolstered its ability to harness machine learning in drug discovery, marking a significant milestone in its evolution. This historical trajectory illustrates the company’s commitment to innovation and its willingness to embrace new technologies that can catalyze breakthroughs in precision medicine.

Research and Development Focus

Key Therapeutic Areas
Relay Therapeutics has established its research and development (R&D) focus around two primary therapeutic areas:

1. Targeted Oncology:
A significant portion of their R&D is centered on the discovery and development of small molecule therapies targeting various cancers. Their primary focus is on designing inhibitors for mutated protein targets, such as fibroblast growth factor receptor 2 (FGFR2) and phosphoinositide 3 kinase alpha (PI3Kα). For instance, RLY-4008, an oral FGFR2 inhibitor, is being evaluated in a first-in-human clinical trial specifically targeting FGFR2-altered solid tumors including cholangiocarcinoma—a bile duct cancer recognized for its challenging treatment landscape. Moreover, RLY-2608 targets multiple oncogenic PI3Kα mutations, demonstrating the company’s dedication to addressing mutations that have long been considered intractable by conventional drug discovery strategies.

2. Genetic Diseases:
In addition to oncology, Relay Therapeutics extends its precision medicine approach to address genetic disease indications. By understanding protein dynamics and using the Dynamo platform, the company aims to create highly selective inhibitors that can modulate pathways implicated in congenital disorders and other genetic conditions. This dual focus supports a diversified pipeline while leveraging the same underlying technological principles to potentially impact multiple disease domains.

These therapeutic areas are chosen not only because of the significant unmet medical needs but also due to the inherent challenges they present. Traditional approaches have frequently fallen short of successfully addressing the complex biology of these diseases, thereby creating opportunities for Relay’s platform to demonstrate its potential through improved target engagement and reduced off-target toxicity.

Technologies and Platforms
The cornerstone of Relay Therapeutics’ innovation is its proprietary Dynamo™ platform. This cutting-edge platform integrates an array of computational and experimental approaches with the following key features:

1. Computational Protein Dynamics:
By leveraging high-resolution structural data, the Dynamo platform uses sophisticated algorithms to simulate protein motion. Understanding the dynamic behavior of proteins is critical to identifying novel binding sites and designing inhibitors that can effectively modulate a target’s function. This dynamic perspective marks a departure from traditional static approaches and allows Relay to tackle protein targets previously deemed challenging.

2. Machine Learning and Artificial Intelligence:
The integration of artificial intelligence is a critical element of Relay’s strategy. The acquisition of ZebiAI, a company specializing in machine learning for drug discovery, has allowed Relay to harness vast experimental datasets, such as those from DNA-encoded libraries (DELs), to enhance predictions of drug-like chemical starting points. This acquisition further accelerates the cycle time for compound optimization and increases the robustness of candidate selection.

3. Integrated Experimental Approaches:
Complementing its advanced computational techniques, Relay employs high-throughput experimental methods to validate predictions and refine models iteratively. This dual approach of computation followed by experimental confirmation ensures high fidelity in the transition from candidate discovery to clinical validation.

4. Platform Synergies:
The Dynamo platform sits at the intersection of several disciplines, including computational biology, biochemistry, and medicinal chemistry. It enables the company to quickly iterate on insights and adapt to new data, continuously improving the predictive power of their systems. Such integration is vital for creating a flexible and scalable drug discovery engine that can address diverse targets spanning oncology and genetic diseases.
