CROs are crucial in cancer research for several reasons: 1. Expertise and Resources: CROs have specialized knowledge and resources that can accelerate the pace of cancer research. 2. Regulatory Compliance: They ensure that studies comply with stringent regulatory requirements set by agencies like the FDA and EMA. 3. Cost-Effectiveness: Outsourcing to CROs can be more cost-effective than conducting research in-house, particularly for smaller biotech companies. 4. Global Reach: Many CROs have a global presence, which is essential for conducting multi-center clinical trials that require a diverse patient population.
