## About Relay Therapeutics

## Company Overview
- **One-liner**: Relay Therapeutics is a clinical-stage precision medicines company that uses its Dynamo® platform to visualize protein motion and drug previously intractable targets, with an initial focus on precision oncology and genetic disease.
- **Entity Type**: Public (NASDAQ: RLAY)
- **Headquarters**: Cambridge, Massachusetts, United States
- **Founded**: 2016
- **Founders**: Not publicly listed as individual founders; the company was launched by Third Rock Ventures.

## Core Business
- **Primary industry/industries**: Biotechnology, Precision Oncology, Genetic Disease Therapeutics
- **Target customers**: Patients with specific cancer mutations (e.g., PI3Kα, FGFR2, NRAS) and rare genetic diseases (e.g., Fabry disease, PROS); partners are healthcare providers, clinical trial sites, and regulatory bodies.
- **Mission or purpose statement**: "We aim to drug the undruggable." The company is laser-focused on bringing life-changing medicines to patients by visualizing protein motion to discover new therapeutics.

## Products & Services
- **Dynamo® Platform**: A proprietary drug discovery platform that integrates long-timescale molecular dynamics (MD) simulations, cryo-electron microscopy (cryo-EM), and other biophysical techniques to visualize protein motion and identify novel drug binding sites. This is the core technology enabling all pipeline programs.
- **Zovegalisib (RLY-2608)**: A clinical-stage, allosteric, pan-mutant and isoform-selective PI3Kα inhibitor. It is designed to overcome the toxicity of orthosteric inhibitors by sparing wild-type PI3Kα. Currently in a Phase 3 trial (ReDiscover-2) for HR+/HER2- PI3Kα-mutated advanced breast cancer and a Phase 1/2 trial for PROS and vascular anomalies.
- **Lirafugratinib (RLY-4008)**: A selective FGFR2 inhibitor. In December 2024, global development and commercialization rights were out-licensed to Elevar Therapeutics.
- **RLY-8161**: A first-in-class, NRAS-selective inhibitor designed to address the liabilities of pan-RAS inhibitors. Currently in a Phase 1/2 trial for NRAS-mutant melanoma and other solid tumors.
- **Fabry Disease Program**: An investigational non-inhibitory chaperone designed to stabilize the αGal enzyme without inhibiting its activity, potentially offering a chronic treatment option for Fabry disease. Currently in IND-enabling studies.

## Market Standing
- **Valuation/Market Cap**: $909.1 million (as of mid-2026) [linkedin.com](https://www.linkedin.com/company/relay-therapeutics-inc.)
- **Key Metric**: Annual Revenue of $15.4 million (pre-commercial, primarily from collaboration/grants) [linkedin.com](https://www.linkedin.com/company/relay-therapeutics-inc.)
- **Total Funding**: $1.8 billion (including IPO and follow-on offerings) [linkedin.com](https://www.linkedin.com/company/relay-therapeutics-inc.)
- **Notable Investors/Partners**: Third Rock Ventures (founding investor), Nextech Invest, Elevar Therapeutics (out-license partner for lirafugratinib).

## Competitive Advantages
- **Dynamo® Platform Moat**: The company's core differentiator is its ability to use long-timescale molecular dynamics simulations to visualize protein motion. This allows them to drug targets (like allosteric sites on PI3Kα and NRAS) that are "undruggable" with traditional static-structure approaches.
- **Selectivity & Tolerability**: Their lead asset, zovegalisib, is designed to be a pan-mutant, isoform-selective PI3Kα inhibitor. This selectivity for mutant over wild-type PI3Kα is a key advantage over first-generation orthosteric inhibitors, potentially offering better efficacy and chronic tolerability.
- **First-in-Class Potential**: RLY-8161 is described as the first NRAS-selective inhibitor, addressing a major unmet need in NRAS-mutant cancers by sparing KRAS and HRAS, which are responsible for the toxicity of pan-RAS inhibitors.

## Strategic Focus
- **Advancing Late-Stage Pipeline**: The primary focus is on executing the Phase 3 ReDiscover-2 trial for zovegalisib in breast cancer and expanding its potential in vascular anomalies (PROS).
- **Expanding Pipeline**: Advancing RLY-8161 (NRAS) through Phase 1/2 and moving the Fabry disease program toward clinical trials.
- **Platform Validation**: Continuing to use the Dynamo® platform to discover new drug candidates for previously intractable targets, thereby validating the platform's broader potential beyond current pipeline assets.
