As the data collection methods have extreme influence over the validity of the research outcomes, it is considered as the crucial aspect of the studies

Contract Research Organizations (CROs) are an important part of the pharmaceutical company with respect to pharmaceutical drug development. In an increasingly complex clinical trial development and regulatory constraints environment, high-quality and evidence-based strategies have never been as important as they are now. One of the strategies that CROs can take advantage of about enhancing their clinical strategy is using meta-analysis. Meta-analysis is aggregating the data from multiple studies to reach robust, statistically meaningful conclusions and provides a more holistic understanding of treatment effect.[1]
This article will look at how CROs can utilize meta-analysis to streamline trial design, enhance patient and community recruitment, provide a development framework for regulatory submission, and occur faster drug development timeframes.
In the ever-increasing competitive environment of the pharmaceutical industry, CROs have the challenge of providing data that is both reliable and actionable. To respond to the ever-increasing demands of regulatory bodies and stakeholders, CROs must provide:

Even with the expertise of CROs, there are still challenges that exist with clinical trials:
FIG 2: Clinical Trial Costs by Phase and Therapeutic Area
This figure shows the variation in trial costs across phases and therapeutic areas, reflecting challenges like study variability and small sample sizes.
Meta-Analysis Benefit | Definition | % Benefit |
Statistical Power and Precision | The advantage of combining data is the increased sample size, which gives greater accuracy and reduced chance of false results. | 30% |
Improved Precision and Confidence | Pooling data will improve the statistical confidence (i.e., minimizing the risk of false positives/negatives). | 25% |
Identifying Small Effects | Potential to identify a small treatment effect that would not be statistically significant in any one trial. | 20% |
Subgroup Analysis | Allows for analysis of subgroups (e.g. age, comorbidities) to derive treatment relevance. | 15% |
A personalized medicine approach | Likely to improve treatment for targeted patient population.[2] | 10% |
Safety Assessment | Allows us to pool adverse events to identify rare or longer-term safety risks. | 10% |
Evaluating durability of treatment effects | Ability to assess durability of treatment effects. | 5% |
Benefit-risk profile | Allows for comparison of efficacy versus safety and provide support for determining benefit-risk profile. | 15% |
Positioning a New Treatment Purpose | Allows us to compare new treatments to existing therapies in support of approval process. | 5% |
Table 1: shows you that meta-analysis boosts clinical strategies by enhancing statistical power, precision, safety, and the benefit-risk profile.

Best Practices for Conducting Meta-Analysis
For a Contract Research Organization (CRO), the meta-analysis can be an important method that can significantly increase a clinical strategy. Meta-analysis can increase statistical power by combining information in many studies, detail subgroup analyses, improve safety, and enhance the benefit-risk assessment of treatments.[5] For a CRO, the addition of meta-analysis into clinical trials and regulatory submissions will advance the speed of drug development and further strengthen the case for approval. Embracing a foundation based on evidence allows for better risk management, improved clinical strategy, and the development of richer, more meaningful, and actionable insights and advice for pharmaceutical companies while speeding the rate to market for new therapies.
