Preclinical development is one of the most critical—and costly—phases in the drug development lifecycle. Yet for many emerging biotech and pharmaceutical companies, this stage can become a bottleneck due to avoidable mistakes. At CALIIRA, we’ve seen firsthand how early missteps can delay timelines, increase burn rates, and reduce investor confidence. In this post, we highlight some of the most common pitfalls in preclinical development and share strategies for avoiding them.
1. Lack of a Clear Preclinical Strategy
The Pitfall:
Many early-stage companies dive into experiments without a well-defined roadmap. This can lead to redundant studies, wasted resources, and gaps in data required for regulatory filings.
How to Avoid It:
Develop a preclinical development plan that aligns with your long-term clinical and regulatory goals. Work with experienced consultants who can help design a strategy that balances speed, risk, and data quality.
2. Inadequate Toxicology Planning
The Pitfall:
Toxicology studies are often rushed or poorly designed, leading to surprises during IND submission or delays in clinical entry.
How to Avoid It:
Engage with toxicologists early in the process. Choose relevant animal models, and ensure your studies meet GLP standards. A robust toxicology package is essential for regulatory clearance and investor confidence.
3. Overlooking CMC (Chemistry, Manufacturing, and Controls)
The Pitfall:
Preclinical teams may deprioritize manufacturing, assuming it’s a downstream concern. This results in formulation issues, batch inconsistencies, or delays in producing clinical-grade material.
How to Avoid It:
Start planning your CMC strategy alongside preclinical studies. Engage with CDMOs early, and ensure your formulations and processes are scalable and compliant with regulatory expectations.
4. Insufficient Documentation and Data Management
The Pitfall:
Disorganized data, missing protocols, or lack of traceability can derail regulatory submissions and complicate future audits or partnerships.
How to Avoid It:
Implement a strong data management system from the start. Maintain well-documented protocols, version control, and audit-ready records. A little upfront organization can prevent costly rework down the road.
5. Ignoring Regulatory Guidance
The Pitfall:
Failing to seek feedback from regulatory agencies can result in misaligned study designs and unexpected IND rejections.
How to Avoid It:
Engage early with regulatory bodies like the FDA through pre-IND meetings. Use their input to refine your preclinical plan. A proactive regulatory strategy helps de-risk your development pathway.
Conclusion
The preclinical stage sets the tone for your entire development program. Avoiding these common pitfalls can accelerate timelines, improve your chances of regulatory success, and demonstrate to investors that your program is built on a strong foundation.
