Apterna’s lead programme begins with a focused, high-need patient group: liver cancer patients whose tumours may be technically removable, but whose liver reserve is too poor to tolerate surgery. By starting where the clinical need is most urgent and the treatment gap is most severe, the programme is designed to create a clear path to proof of concept in a setting where no medicine currently restores the liver function needed to reopen curative options.
Liver-Targeted Delivery
Precision RNA therapeutics for hepatic disorders
Focusing on Conditions of Highest Unmet Need
Many of the most serious diseases remain undertreated because therapies cannot reach the right organ at effective concentrations, or because patients in advanced stages cannot tolerate available regimens safely.
Validated RNA Chemistry
Proven molecular modalities paired with clinically validated, organ-selective delivery
Precision Targeting
Direct delivery to hepatocytes to maximise on-target effect
Reduced Toxicity
Lower systemic exposure to support tolerability in fragile patient populations
Apterna’s platforms are built to address the delivery barrier that limits RNA medicine. Our initial focus is liver-related disease, where obesity, alcohol use, and chronic inflammation drive a growing global burden, and CNS-involved oncology, where effective treatment remains constrained by the blood-brain barrier.
Restoring Liver Health Where It Matters Most
Liver disease is one of the fastest-growing contributors to global morbidity and mortality. Because the liver governs metabolism, detoxification, and inflammatory signalling, dysfunction can rapidly destabilise multiple organ systems and restrict access to life-extending therapies.
Spectrum of Liver Disease Progression
Fatty Liver (Steatosis)
MASH (Steatohepatitis)
Fibrosis
Cirrhosis
Decompensated Cirrhosis and HCC Risk
Liver Failure
Liver failure occurs when the liver loses its ability to perform essential metabolic and synthetic functions. In patients with cirrhosis or severe hepatic injury, treatment options are extremely limited.
Unmet Need:
• 30-40% of patients with primary liver cancer present with severe dysfunction
• Current drugs contraindicated due to hepatic toxicity
• Only palliative care available for many patients
• Current drugs contraindicated due to hepatic toxicity
• Only palliative care available for many patients
Apterna's Focus:
Restore liver function to make patients eligible for standard therapies, extending life expectancy and quality of life.
Hepatocellular Carcinoma
HCC is the most common form of primary liver cancer, frequently developing on a background of cirrhosis, NASH, or viral hepatitis. Global incidence is rising due to the obesity and diabetes epidemic.
Unmet Need:
- • 40% of HCC patients have underlying liver failure
- • Prevents use of chemotherapy, immunotherapy, or surgery
- • Median survival as short as three months
Apterna's Focus:
Improve hepatic function to enable combination with existing cancer treatments, addressing a gap no current therapy fills.
Fatty Liver Disease
Hepatic steatosis arises when excessive fat accumulates in the liver, existing in alcohol-related (ARLD) and metabolic dysfunction-associated (MASLD) forms.
Unmet Need:
• Affects 1 in 4 adults globally
• No approved pharmacological treatment
• Limited efficacy of lifestyle modification
• No approved pharmacological treatment
• Limited efficacy of lifestyle modification
Apterna's Focus:
Modulate metabolic pathways to reduce liver fat and prevent progression to cirrhosis or cancer.
NASH / MASH
MASH is the inflammatory, fibrotic form of fatty liver disease, representing a major public health challenge linked to obesity and metabolic syndrome.
Unmet Need:
• Global therapeutics market remains underdeveloped
• Candidate therapies failed due to poor liver specificity
• Systemic toxicity limits treatment options
• Candidate therapies failed due to poor liver specificity
• Systemic toxicity limits treatment options
Apterna's Focus:
Direct liver action addressing metabolic and inflammatory processes driving NASH, demonstrating improvements in key biomarkers.
Extending Precision RNA Delivery Beyond the Liver
Many aggressive cancers have a high propensity to spread to the brain. Once metastasised, these cancers become extraordinarily difficult to treat because most drugs cannot cross the blood-brain barrier. Apterna’s liver-first strategy also supports broader metabolic care by improving hepatic resilience and enabling safer initiation, escalation, and durability of GLP-1R+ therapy in real-world patients.
Blood-Brain Barrier Penetration
Systemic RNA delivery to CNS tissue
Unmet Need
- ~33% of aggressive breast/lung cancer patients develop brain metastases
- Median survival <6 months after brain metastases diagnosis
- Conventional therapies have limited BBB penetration
Apterna's Brain Platform
- Systemic, non-invasive RNA delivery to CNS
- Effective biodistribution across BBB
- Licensing opportunities for CNS developers
A Focused Entry Point with Broader Liver Disease Relevance
Apterna’s disease-area strategy begins where the unmet need is sharpest and the clinical impact could be most immediate: patients whose liver reserve is too poor to access potentially curative surgery. This gives the programme a tightly defined first setting in which functional liver recovery could change what becomes possible for patients.
From that focused starting point, the same therapeutic logic is intended to extend across the wider liver disease continuum. In the business plan, this means a staged expansion from surgical unlock into cirrhosis and transplant avoidance, and over time into the much larger fatty liver and obesity-related liver market. This approach allows Apterna to begin with a clear proof-of-concept pathway while building relevance across a substantially broader long-term opportunity.
Platform Vision
By enabling precise control over where and how RNA drugs act, Apterna’s platform opens new frontiers for the entire field of nucleic acid medicine.
A Vision for Accessible RNA Medicine
Apterna’s ultimate goal is to make RNA therapy safe, targeted, and accessible. By focusing on delivery systems that are chemically defined, non-viral, and compatible with standard manufacturing, we aim to keep costs manageable and ensure broad patient access.
