Our Goals

Opportunity

Due to rising rates of antibiotic resistance, common infections are increasingly spiraling into life-threatening crises. A lack of new antibiotics in the drug development pipeline means that we are losing the race against bacterial infections, leaving an urgent gap in care for patients. Filling that gap could save millions of lives annually – and redefine a multi-billion market that remains largely underserved

01.

Global Infection Toll

Acute infections—pneumonia, peritonitis, febrile neutropenia — kill millions of people annually, making them one of the world’s leading causes of death. Most patients require hospitalization, and many deteriorate into intensive care. Mortality can reach 15–45 % within the first month. Survivors often endure repeat admissions, organ damage, cognitive fog, and bills exceeding $30,000.

02.

Antibiotics Losing Ground

These grim outcomes unfold despite widespread antibiotic use. Bacteria are evolving faster than antibiotic drug pipelines can replenish them. The WHO warns that within 15–20 years many current antibiotics will be completely ineffective. Without new treatment options, once-routine infections may become untreatable.

03.

Critical Care Gap

ICUs overflow and budgets strain as clinicians exhaust existing treatment options. When antibiotics falter, care teams have no reliable fallback and must rely on expensive and invasive supportive care procedures. Patients and families bear lifelong physical, cognitive, and financial burdens. A resistance-proof therapy would instantly redefine the standard of care.

04.

Vast Market Upside

Treatments for acute infections already cost tens of billions of dollars annually. Breakthrough modalities capable of circumventing resistance could capture a significant portion of that spend. First movers can also address chronic complications that can arise post-infection, currently without treatment. Rarely do humanitarian impact and compelling returns align so clearly.

Our Solution

Resolve Nanotherapeutics uses RNA delivered by lipid nanoparticle technology to rapidly amplify the body’s ability to clear bacterial toxins. This reduces the damaging inflammation associated with acute infections and improves survival by preventing serious complications such as organ damage. This host-focused strategy works on ALL types of bacteria regardless of antibiotic resistance profile and does not have a clear mechanism by which bacteria could evolve resistance.

Host-Focused Strategy

We have studied how the body naturally clears infections and amplify that defence. By dialling up the body’s toxin-clearance pathway, our therapy neutralises every bacterium—sensitive or resistant—without touching the microbe itself. With no direct pressure on pathogens, resistance cannot emerge. Broad-spectrum protection, zero resistance risk.

Genetic Validation Proof

People born with genetic mutations that "turn-on" this toxin-clearance pathway survive sepsis up to 25 % more often. Human genetics and animal studies converge on the same life-saving targets, giving us a uniquely de-risked starting point to develop RNA drugs. Nature has effectively run the first trial. We’re translating that proof into medicine.

Precise RNA Delivery

Clinically proven lipid nanoparticles deliver RNA straight into liver cells, switching target genes on or off within hours. This RNA delivery platform is highly programmable and easy to scale. A single i.v. dose can quickly and potently ramp up the toxin clearance pathway when patients need it most.

Our Technology

RNA-based therapeutics can be programmed to turn “on” or “off” any therapeutic target protein in the right cells in a rapid and clinically relevant timescale.

Natural Immunity

Our LNP‑RNA therapy switches "on" the body’s toxin‑clearing system. This amplifies the body's own innate defences and helps to flush bacterial toxins that accumulate during severe infection. Patients recover faster with less organ damage.

Broad Spectrum

By boosting the immune system of the host, not attacking microbes, our therapy works on every bacterial species, sensitive or resistant, addressing mixed ICU infections without driving new resistance.

Novel Druggability

Validated gene targets switch "on" or "off" within hours through plug‑and‑play LNP‑RNA, enabling the targeting of biological pathways that cannot be targeted by traditional small molecule approaches.

Novel · Broad Spectrum · Effective

Our host-focused LNP-RNA therapy has already cut mortality in resistant pneumonia models—showing how a single dose can outflank pathogenic bacteria and protect fragile lungs.

Jim Russell, MD. - Co-Founder and Board Chair

Dr. Russell has 43 years experience doing research on severe infections. His main focus has been discovery of biomarkers and novel therapeutics.  Dr. Russell has pivoted to research on community-acquired pneumonia (CAP), the commonest cause of sepsis, a more homogeneous condition than sepsis for mechanistic and drug discovery.  He was a founder of Sirius Genomics and Cyon Therapeutics. He is the #1 global expert in septic shock research (Expertscape; 326 publications. H index 93). He has led trials in septic shock and COVID-19, and during and after the COVID pandemic he secured $7M CIHR, St. Paul’s Foundation and other funding for the CAPtivate program (27 publications) and has raised $23.5M as a co-investigator. He has extensive experience with murine and human sepsis and was a co-discoverer of the central role of PCSK9 in severe infections.
