Overcoming the Challenges of Rapid Hit Identification in Drug Discovery

The Race Against Time in Biotech Innovation

In the fast-paced world of drug discovery, venture-backed biotech companies are under immense pressure to deliver breakthroughs swiftly. With investors eager for progress and patients waiting for new therapies, the need to rapidly identify high-quality hits for novel targets is more critical than ever. Yet, this urgency often collides with the complexities of modern drug development, where traditional methods may fall short.

The Complexities of Novel Targets and Modalities

Today’s therapeutic landscape is evolving with unprecedented speed. Biotechs are exploring uncharted territories—novel targets, new therapeutic modalities like RNA therapeutics and molecular glues, and complex biological systems. While these advancements hold great promise, they also present unique challenges:

• Lack of Established Protocols: Novel targets often lack established assays or screening methods, requiring custom development from scratch.
• Complex Biological Interactions: New modalities involve intricate mechanisms of action that standard assays may not adequately capture.
• Data Quality Demands: High-throughput screening generates vast datasets, but without precision and reliability, this data can lead to false leads and wasted resources.

The Implications of Delayed Hit Identification

Delays in the hit identification phase can have cascading effects throughout the drug development pipeline. Extended timelines not only consume valuable resources and capital, putting additional strain on budgets, but they can also lead to a competitive disadvantage, as slow progress may result in falling behind competitors working on similar targets or indications. Furthermore, venture capital firms expect timely milestones, and delays can strain these critical relationships, ultimately impacting future funding.

Leveraging Strategic Biotech-CRO Partnerships

To navigate these challenges, many biotechs are turning to Contract Research Organisations (CROs) that offer specialised expertise and technologies. A partnership mentality is crucial—not just outsourcing tasks but collaborating closely to achieve shared goals.

Benefits of a Collaborative CRO Relationship

Benefits of a Collaborative CRO Relationship encompass several key advantages. First, CROs can work with you to develop bespoke assays that address the specific nuances of your target, including protein production and quality control. Additionally, you can leverage cutting-edge platforms like the Ulysses^® automation platform for high-throughput and high-precision screening without the need for capital investment. Moreover, CROs often have multidisciplinary teams composed of biochemists, data scientists, and assay development specialists, providing insights that might be beyond your in-house capabilities. Lastly, these organizations offer flexible and scalable resources, allowing you to adjust the scope and scale of your projects quickly in response to new data or strategic shifts.

Real-World Example: Accelerating Hit Identification Through Partnership

Consider a biotech company working on a challenging enzyme target with no existing assays. By partnering with a CRO like Arctoris, they collaborated to develop custom assays, designing and validating an assay tailored to their target’s unique properties, which enabled accurate measurement of activity. They also created bespoke automation utilizing the Ulysses® platform, allowing them to screen thousands of compounds in full dose-response mode, dramatically reducing the time required while immediately generating a large-scale, rich dataset. The precision of the automated systems further reduced variability, leading to more reliable hit identification with robust Z’ scores consistently above 0.7. This partnership ultimately enabled the biotech to identify viable hits in a fraction of the time it would have taken independently, conserving resources and fulfilling investor expectations.

Navigating Unexpected Challenges Together

In drug discovery, unexpected challenges are the norm rather than the exception. A strong CRO partnership facilitates rapid problem-solving by providing immediate access to a broader knowledge base when unforeseen issues arise, such as assay interference or compound instability. This collaborative relationship also allows for strategic adjustments, enabling teams to pivot project focus based on emerging data without significant delays, such as adjusting screening strategies according to initial hit profiles. Additionally, when both parties are outcome-oriented and committed to project success, it permits dynamic resource reallocation at short notice, allowing the science to guide the project and maintaining momentum.

Conclusion: Building Success Through Collaboration

Accelerating hit identification is not just about technology—it’s about relationships. By fostering a partnership mentality with a CRO, biotechs can navigate the complexities of modern drug discovery more effectively. Together, they can turn challenges into opportunities, leading to successful outcomes that benefit all stakeholders.
