The U.S. Department of Defense has awarded a substantial grant of $11.9 million to the Oregon State University (OSU) College of Pharmacy, with the aim of developing advanced drug delivery technologies specifically designed to protect military personnel from various health threats encountered in combat areas. This ambitious project is spearheaded by nanomedicine researcher Gaurav Sahay, who holds dual appointments at OSU and the Oregon Health & Science University, highlighting the collaborative nature of this endeavor.
DARPA’s Hermes Program
Fueling this initiative is the Defense Advanced Research Projects Agency (DARPA), which channels its support through the Hermes program. The primary objective of this program is to discover innovative and efficient methods of delivering therapeutic agents throughout the body while minimizing toxicity. Named after Hermes, the messenger of the gods and guardian of travelers in Greek mythology, the program underscores the deliverance of vital information and protection, reflecting its mission to enhance health outcomes for military personnel by leveraging cutting-edge technology.
Innovative Drug Delivery Methods
Central to DARPA’s Hermes program is the exploration of pioneering techniques for drug delivery. This initiative identifies and develops groundbreaking methodologies that ensure therapeutic agents reach their target destinations within the body with greater precision and reduced adverse effects. These advancements are essential for addressing the complexities and risks associated with conventional drug delivery systems. By focusing on innovative drug delivery methods, DARPA aims to enhance the efficacy and safety of treatments, contributing to the well-being of those in military service while setting new benchmarks in pharmaceutical research.
Focus on mRNA Delivery
A significant aspect of the research under this program is the intracellular delivery of messenger RNA (mRNA) to various cell and tissue types. This focus is driven by the potential of mRNA therapies to revolutionize the treatment of diseases and conditions that are otherwise difficult to address with traditional pharmaceuticals. Sahay and his team will delve into the utilization of lipid nanoparticles as carriers of mRNA, building on the success of similar technologies used in the development of coronavirus vaccines. This approach aims to mitigate the negative side effects and challenges associated with broad systemic delivery, optimizing the therapeutic impact while minimizing harm.
Lipid Nanoparticles: The Core Technology
Composition and Function
At the heart of this research are lipid nanoparticles, which serve as the primary vehicles for delivering mRNA to targeted cells. These nanoparticles are composed of lipids—organic compounds found in oils and waxes—crafted into particles ranging in size from one- to 100-billionths of a meter. Their minuscule size allows for efficient encapsulation of large, complex biologics, facilitating their transport across cellular barriers. The development of novel platforms and formulations capable of effectively encapsulating and protecting these biologics is crucial. This ensures that they reach their intended intracellular destinations and exert their therapeutic effects where they are needed the most.
Immune System Response
A critical aspect of the project involves understanding and mitigating unwanted immune system responses. Ensuring that the therapeutic cargo within nanoparticles reaches its intended cellular destination without triggering adverse immune reactions is paramount to the success of these advanced drug delivery systems. Researchers will investigate the interactions between lipid nanoparticles and the immune system, aiming to refine the formulations to be both safe and effective. By addressing these immunological challenges, the team hopes to create a robust delivery system that can be widely implemented in various medical contexts, offering reliable protection and treatment options.
Practical Applications and Goals
Administration Methods
The practical applications of this research are far-reaching, with significant implications for public health and military preparedness. One of the key goals is to develop methods for administering these nanoparticles via inhalation or subcutaneous injection. These routes of administration are designed to provide rapid and effective protection against a range of threats, including infectious diseases, ionizing radiation, and chemical and biological agents. The versatility and efficacy of these administration methods represent a significant advancement in the deployment of nanotechnology for health protection, enhancing the readiness and resilience of military personnel in combat environments.
OSU’s Esteemed Position
The recognition and funding from DARPA highlight Oregon State University’s esteemed position in the field of intracellular drug delivery. For Gaurav Sahay and his team, this award is seen as the culmination of a decade’s worth of pioneering work in lipid nanoparticles and mRNA delivery. Their collaborative efforts at the Center for Innovative Drug Delivery and Imaging (CIDDI) have laid a strong foundation for this project, showcasing OSU’s leadership and expertise in this cutting-edge field. The continued support and investment underscore OSU’s vital role in advancing medical research and technology, particularly in the context of nanomedicine.
Collaborative Efforts and Expertise

This team comprises experts from various disciplines, including Adam Alani, Oleh Taratula, Olena Taratula, Conroy Sun, and Yulia Eygeris from OSU, as well as Jon Hennebold and Ben Bruwitz from the Oregon National Primate Research Center. Additionally, members from Rare Air Health, Inc. contribute their specialized knowledge and skills, creating a robust and dynamic collaborative environment. This multidisciplinary approach ensures that the project benefits from a wide range of perspectives and expertise, enhancing its potential for success and innovation.
Project TALARIA
The project has been aptly named TALARIA—an acronym for tailored, adaptive lipid nanoparticles for aerosolization and intramuscular administration. This name reflects the focused efforts and innovative strategies developed by the research team. TALARIA represents the culmination of extensive research and development, underscoring the promising potential of these advanced technologies to address critical health challenges. The collaboration among these esteemed researchers and institutions highlights the importance of teamwork in pushing the boundaries of science and technology, ultimately driving progress in the field of nanomedicine.
Broader Implications and Future Trends
