How Biotechs Can Streamline Their Preclinical Research Timelines

The drug development process is one that is long, complex, and expensive, involving multiple phases of research, testing, and regulatory oversight.

As a researcher, it's essential to understand the drug development process and recognize how preclinical studies influence its progress. Preclinical research plays a pivotal role in shaping the success of drug development by mitigating risks, establishing efficacy, and guiding clinical trial design.

At Mispro, we help researchers run their own studies, offering affordable, flexible, and fully supported in vivo research solutions. Our state-of-the-art contract vivarium facilities and expert services accelerate preclinical timelines and ensure high-quality results.

For researchers running their own studies, here’s what to know about the preclinical research timelines and how to navigate the preclinical phase in drug development efficiently and effectively at a contract vivarium facility.

How Long Does Preclinical Research Take?

At Mispro, our IACUC team reports that the preclinical research process takes anywhere from a few months to over a year. Expectations for timelines can vary widely depending on the study:

• Pharmacokinetics/Pharmacodynamics (PK/PD) studies typically take about 28 days, including dosing and blood/tissue collections.
• Small molecule studies usually run 4–8 weeks after animal acclimation.
• Gene therapy studies tend to be quicker, averaging 1–2 months.
• Immunology studies are among the longest, lasting 4+ months because of disease induction and immune response tracking.
• Oncology studies often take 3+ months, with some extending to 9–12 months due to tumor growth and monitoring.

Common Reasons for Preclinical Research Timeline Delays

Preclinical research is a pass/fail process that aims to fail fast in order to move forward efficiently. These studies help establish a strong foundation for clinical trials, bringing the drug candidate closer to market approval while minimizing risks and optimizing timelines.

Here are a few factors that can affect preclinical research timelines:

1. Study Design & Complexity
2. Field of Study
3. Early Failures
4. Animal-Related Factors
5. Regulatory & Administrative Process
6. Scheduling & Facility Availability
7. Biotech Readiness
8. Study Execution & Success

Read more about each reason below:

1. Study Design & Complexity

The overall complexity of your study has a major impact on your timeline. Simple PK/PD studies with clear collection time points often take 4–8 weeks, while more complex models like tumor or disease progression studies can stretch into several months. The type of data you’re collecting also shapes the schedule. Some studies require monitoring over time to hit specific biological milestones before proceeding.

2. Field of Study

Different research areas come with different timelines. Gene therapy studies tend to move quickly and may wrap in as little as a month. In contrast, oncology studies typically last 3 months or more, as tumor growth and response must be observed over time. Immunology studies are often the most time-consuming, with durations of 4 months or longer, due to complex immune responses and extended observation periods.

Average Preclinical Timeline by Research Area

• Gene Therapy: ~1 month. Fastest; straightforward studies
• PK/PD: ~4-8 weeks. Structured, predictable
• Oncology: ~3 months+. Tumor growth adds variability
• Immunology: ~4+ months. Complex, high variability

3. Early Failures

Early failures in drug development can significantly extend timelines, but catching issues early through preclinical testing helps prevent costly setbacks later. Around 25% of studies don’t run as expected—often due to factors like study design, unexpected findings, or operational issues like animal delivery errors or health concerns—not due to the facility itself.

“Failing fast” in preclinical studies is crucial for minimizing delays and reducing costs in drug development. By identifying issues early, such as flaws in study design, unexpected findings, or operational problems like animal delivery errors, researchers can quickly adapt and adjust their approach.

4. Animal-Related Factors

Animal sourcing marks the starting point of most preclinical timelines. Delays can occur due to limited availability of specific strains, high demand, or biosecurity concerns that require quarantine or additional health screening. Compatibility between animal source and study requirements is critical; misalignment can lead to reordering or protocol adjustments.

5. Regulatory & Administrative Process

Depending on species used and/or federal/state/local regulations, regulatory approval may be required for starting in vivo studies. Institutional Animal Care and Use Committee (IACUC) review timelines vary, however experienced IACUCs can generally approve submissions within 30 days. There may be other permits, licensing, etc. that may impact study timelines, such as DEA licensing, MTAs, etc.

6. Scheduling & Facility Availability

Timing access to vivarium space depends on facility operations and scheduling protocols. In shared-use facilities, study start dates often hinge on room availability and prior commitments. The period between finalizing legal agreements and initiating a study can also be affected by how quickly space opens up and how ready the sponsor is to proceed.

7. Biotech Readiness

One of the most overlooked preclinical timeline factors is internal preparedness. If you're missing necessary materials, equipment, or haven't trained your team yet, your study will be delayed. Back-ordered components and gaps in staffing—especially in early-stage biotechs—can cause studies to start late or stall midstream. Planning ahead and clearly understanding what’s required to begin can save weeks.

8. Study Execution & Success

While many studies proceed as planned, it's not uncommon for ~25% to face unexpected challenges or early termination. Factors include protocol deviations, unanticipated results, or shifts in project direction. While early failure is sometimes inevitable in exploratory work, identifying issues early through strong study design and oversight can reduce downstream disruption.

Why Contract Vivarium Right Option for Preclinical Research

Let’s take a closer look at the options for preclinical research available to Biotechs.

In-House Vivarium

Building your own vivarium for preclinical research involves high costs, ongoing maintenance, and regulatory compliance, which can extend timelines. It also requires skilled staff and significant time, with challenges in scaling and adapting to new technologies slowing progress.

Contract Research Organizations (CROs)

Outsourcing preclinical studies to a CRO can slow progress by removing control from your team and introducing delays caused by misaligned priorities and limited scheduling flexibility. Ultimately, a lack of control can cause delays and less certainty in the results, slowing down the process.

Contract Vivarium

A contract vivarium gives researchers control over their studies, access to full support and equipment, and the flexibility to move quickly. It’s a cost-effective way to accelerate timelines, adapt to setbacks, and generate stronger data to guide clinical trial design.

Contract vivariums provide the perfect balance of control, flexibility, and speed, making them the best choice for biotech companies looking to accelerate preclinical research.

How Biotechs Can Speed Up The Preclinical Research Process

To get the most value from a Contract Vivarium facility, biotech companies should understand the role of a CV, and be prepared to take ownership of their own research. At Mispro, we’re here to help you efficiently run your own preclinical studies. We’re more than just lab space – we offer support services to help you run your studies.

Education on the Contract Vivarium Process

Misaligned expectations between clients, especially those from CRO backgrounds, and Contract Vivariums can lead to confusion and delays. Ensure your team understands CV processes to streamline operations. Mispro provides onboarding and support to ease this transition.

Make Sure You’re Ready to Lead Your Own Studies

While many biotech teams have strong scientific backgrounds, they may lack hands-on in vivo study experience. Equip your team with skills like injection techniques and study design to confidently manage your research. Mispro offers training to fill knowledge gaps and ensure smooth execution.

Mispro can help fill common knowledge gaps, including:

• Injection techniques
• Study design planning
• Proper equipment ordering
