Oligonucleotides (ONs), short synthetic strands of nucleotides—the fundamental units of DNA and RNA—are rapidly emerging as groundbreaking agents in molecular medicine. Unlike conventional drugs that often target downstream symptoms, ONs intervene at the genetic level by delivering precise molecular instructions that modulate gene expression. By selectively binding to RNA, these molecules can inhibit the production of deleterious proteins directly responsible for pathological conditions such as cancer and chronic inflammatory diseases, thus halting disease progression at its root.

Despite their revolutionary potential, oligonucleotide therapies face critical challenges that hinder their widespread clinical adoption. Chief among these are their inherent instability within biological systems, making them susceptible to rapid degradation by nucleases in the bloodstream. Additionally, achieving effective and targeted delivery to the appropriate cell types remains difficult due to physiological barriers. Compounding these issues, off-target effects and immune system activation sometimes cause adverse reactions. The new ON-TRACT project is laser-focused on overcoming these hurdles by developing novel stabilization methods, optimized delivery vehicles, and safety-enhancing formulations.

The ON-TRACT consortium’s multi-disciplinary approach leverages expertise from synthetic chemistry, chemical engineering, molecular biology, and clinical sciences to develop robust oligonucleotide platforms capable of precise targeting and sustained activity. Advanced chemical modifications of the oligonucleotide backbone and sugar-phosphate moieties are being engineered to enhance nuclease resistance while preserving or improving hybridization affinity for target RNA sequences. These semi-synthetic nucleic acid analogues aim to prolong therapeutic half-life and reduce immunogenicity.

Efficient intracellular delivery is another cornerstone of the ON-TRACT research agenda. The project explores innovative carriers such as lipid nanoparticles, conjugated peptides, and polymer-based nanoparticles that can navigate the complex cellular microenvironment. These vectors are designed to facilitate the endosomal escape of ONs, ensuring their bioavailability within the cytoplasm or nucleus where gene regulation occurs. Researchers are carefully tuning the physicochemical properties of these carriers to optimize biodistribution and minimize off-target interactions or toxicity.

A particularly transformative dimension of ON-TRACT is its commitment to sustainability and ethical experimentation. Rather than relying on animal models, the project adopts cutting-edge organoid technology, cultivating three-dimensional mini-organs from patient-derived stem cells. These organoids faithfully recapitulate human tissue architecture and function, enabling high fidelity preclinical assessment of oligonucleotide efficacy and safety. This paradigm not only accelerates translational research but also aligns with evolving regulatory and ethical standards prioritizing reduction of animal use.

Training the next generation of life science innovators is integral to the ON-TRACT endeavour. Fourteen doctoral candidates distributed across academic, industrial, and clinical partner institutions in multiple European countries—including the UK, Sweden, France, Poland, Belgium, and Italy—will receive rigorous interdisciplinary education. Their research projects will span fundamental nucleic acid chemistry, formulation science, delivery system engineering, and translational oncology, preparing them to be leaders in the burgeoning fields of nucleic acid therapeutics and precision medicine.

The therapeutic focus of ON-TRACT spans several critical diseases with high unmet medical need, including lung cancer, hematological malignancies such as blood cancers, and chronic inflammatory conditions. These complex diseases often elude existing drug modalities due to genetic heterogeneity and dynamic pathological mechanisms. By harnessing the molecular specificity of oligonucleotides, the project aims to tailor treatments that are not only highly effective but also minimize systemic toxicity, heralding a new era of personalized medicine.

The University of Southampton spearheads this effort, collaborating closely with distinguished partners such as the University of Cambridge, Karolinska Institute, AstraZeneca, Centre Nationale de la Recherche CNRS, and others, reflecting a robust European research network. Together, the consortium pools diverse expertise and cutting-edge technologies to push oligonucleotide science from the bench to bedside, addressing major challenges that have so far limited clinical impact.

This initiative complements Southampton’s involvement in the INT2ACT consortium, which focuses on nucleic acids (NAs) broadly as diagnostic and therapeutic tools. While INT2ACT advances nucleic acid applications across multiple disease spectra, ON-TRACT zeroes in on refining oligonucleotide stability, delivery, and safety specifically for cancer and chronic inflammation. This symbiotic relationship between projects amplifies scientific progress and accelerates pipeline development for nucleic-acid-based medicines.

The future envisioned by ON-TRACT could radically alter current paradigms in oncology and immunomodulation, providing patients with targeted treatments capable of rewiring their genetic circuitry. As oligonucleotide therapies gain traction, the promise of durable remissions, fewer side effects, and tailored therapeutic regimens becomes increasingly attainable. These advances are poised to reshape healthcare by aligning molecular precision with patient-specific biology.

In addition to their therapeutic promise, oligonucleotide technologies hold wider implications for sustainable pharmaceutical manufacturing. ON-TRACT explores greener synthesis methods to reduce environmental impact, including enzymatic synthesis and minimization of hazardous reagents. This sustainability focus aligns with global trends for eco-friendly drug production and responsible innovation, ensuring that progress benefits both health and planetary wellbeing.

In summary, the ON-TRACT project represents a bold and comprehensive effort to overcome longstanding barriers in oligonucleotide therapeutics. By integrating cutting-edge chemistry, advanced delivery science, ethical model systems, and extensive training initiatives, the consortium is laying the groundwork for transformative treatments for cancer and chronic inflammatory diseases. With its multisectoral European collaboration and visionary scientific agenda, ON-TRACT is positioned to accelerate the arrival of next-generation precision medicines that target the genetic origins of disease with unprecedented accuracy and safety.

Until now, much of artificial intelligence’s contributions to healthcare have largely been confined to retrospective analyses or theoretical models, leaving a vast potential unfulfilled in direct clinical application. However, led by Professor Dean Ho, Director of the Institute for Digital Medicine (WisDM) at NUS Medicine, the research team has deployed the CURATE.AI platform in a real-world clinical setting—specifically at the National University Cancer Institute, Singapore (NCIS). Their system employed continuous monitoring of two hallmark cancer biomarkers, carcinoembryonic antigen (CEA) and cancer antigen 125 (CA125), across a cohort of 10 patients diagnosed with advanced solid tumors to develop personalized digital twins. These digital twins serve as intimate virtual replicas of individual patients’ tumor biology and therapeutic responses, enabling precise real-time calibration of chemotherapy doses.

By meticulously analyzing the dynamic biomarker fluctuations in response to varying chemotherapy doses, the CURATE.AI platform guided clinicians to adjust treatment regimens with unprecedented precision. Remarkably, over a treatment period spanning from August 2020 to September 2022, 97.2% of the AI-recommended dose modifications were adopted by clinicians. The adjustments led, on average, to approximately 20% lower drug doses in some patients, spotlighting the promising potential to not only maintain therapeutic efficacy but also reduce chemotherapy-induced toxicity and associated healthcare costs.

Traditional oncology often relies on standardized dosing protocols derived from population averages, largely overlooking the considerable heterogeneity in patient responses and tumor evolution during the course of treatment. This limitation presents a pressing challenge as tumor physiology and drug sensitivity are far from static, varying significantly over time within each patient. CURATE.AI circumvents this challenge by harnessing patient-specific, longitudinal clinical data—integrating drug type, administered dose, and objective biomarker responses—to construct an evolving digital pharmacodynamic model. This model empowers the selection of an optimal chemotherapy dose tailored to the patient’s unique, contemporary tumor landscape.

Professor Dean Ho emphasized the innovative nature of this approach, highlighting that many extant AI systems are constrained by reliance on population-level static datasets or retrospective analyses. By contrast, CURATE.AI dynamically responds to individual patient data in real time, effectively capturing intra-patient variability and the continuous metabolic interplay between chemotherapeutic agents and tumor cells. This represents a crucial paradigm shift, enabling iterative, adaptive treatment optimization and heralding the onset of truly precision-guided oncology.

The clinical lead, Associate Professor Raghav Sundar, underscored the translational importance of this study. He reflected on the historical challenge faced by oncologists striving for personalized chemotherapy dosing due to the lack of suitable tools to objectively and dynamically tailor drug regimens. The CURATE.AI trial’s promising findings lay important groundwork for future expansive randomized controlled trials, poised to rigorously evaluate the platform’s efficacy and safety relative to standard-of-care protocols. The clinical implications extend beyond dosing precision, promising to mitigate adverse drug reactions and enhance patient quality of life.

At the core of CURATE.AI’s success lies its sophisticated algorithmic architecture that synergizes Bayesian optimization with mechanistic understanding of cancer biomarker kinetics. Such integration facilitates high-fidelity forecasting of dose-response curves unique to each patient. Furthermore, by repeatedly recalibrating dose selections based on biomarker feedback, the AI system adapts seamlessly to tumor evolution and drug resistance mechanisms that often undermine long-term chemotherapeutic success.

Beyond the study’s immediate oncology focus, the researchers are optimistic about the wider applicability of the CURATE.AI platform across diverse therapeutic domains. Preliminary adaptations are underway to extend its functionalities into immunotherapy regimens, hypertensive medication titration, and interventions designed to enhance healthspan within the longevity medicine landscape. This versatility underscores CURATE.AI’s foundational potential to revolutionize personalized dosing strategies well beyond its initial cancer cohort.

A vital insight from this work, highlighted by co-author Nigel Foo, is the recognition that therapeutic data efficacy is contingent not merely on volume, but on strategic, context-sensitive acquisition. By synchronizing incremental drug dose changes with concomitant biomarker trajectories, CURATE.AI capitalizes on temporal data richness, exposing nuanced pharmacodynamic interactions that are otherwise obscured in traditional clinical datasets. The concept of digital twins crystallizes this insight, enabling a feedback loop of data-driven, patient-specific care planning.

This research represents one of the first tangible illustrations of an AI-driven platform being integrated into everyday clinical treatment decisions, moving beyond the laboratory or theoretical sphere into the practical domain where patients benefit directly. The feasibility trial lays a robust foundation for subsequent multi-center trials with larger sample sizes designed to scrutinize the platform’s reproducibility and impact on long-term clinical outcomes such as progression-free survival and overall survival.

Published recently in the distinguished journal npj Precision Oncology, the findings position CURATE.AI at the frontier of next-generation oncology therapeutics. While conventional cancer care largely depends on pre-defined dosing schemas resistant to mid-course alterations, CURATE.AI epitomizes an adaptive, continuously learning system. Such agility aligns with the emerging understanding of cancer as a highly heterogeneous and time-variant disease, necessitating equally dynamic treatment strategies.

Ultimately, the success of this AI-enabled personalized dosing platform holds profound implications for healthcare economics. By potentially lowering drug dosages without compromising efficacy, CURATE.AI could alleviate the financial burden on healthcare systems and patients alike while limiting exposure-related toxicities that diminish patients’ quality of life. This dual advantage represents a compelling incentive for accelerating regulatory approval processes and clinical adoption worldwide.

As the oncology community grapples with escalating complexity in cancer management and burgeoning molecular data streams, CURATE.AI exemplifies the transformative convergence of digital health technologies with precision medicine. Its ability to deliver individualized, evidence-based treatment adjustments in real time crystallizes the promise of AI not merely as an analytical tool, but as a direct driver of improved patient outcomes in routine clinical care.
