A contract research organization (CRO) is a company hired by a drug, vaccine or device maker (the sponsor) to run some or all of its clinical research work — such as trial planning, site monitoring, data management, drug safety, biostatistics, medical writing and regulatory submissions. The sponsor can hand over tasks but stays responsible for the trial under ICH-GCP. In India, CROs must register with CDSCO’s Central Licensing Authority under rules in force since 1 April 2025. CROs are among the largest employers of CRAs, data managers and drug safety associates.
Key takeaways
- A CRO runs clinical research tasks for a sponsor, project by project.
- Sponsors can delegate work to a CRO but stay accountable (ICH-GCP).
- India now requires CRO registration (Form CT-07B, valid 5 years, from 1 April 2025).
- CROs differ from SMOs, which support trial sites and investigators.
- Entry CRO jobs: CTA, CRA trainee, Clinical Data Coordinator, Drug Safety Associate.

What is a contract research organization?
A new medicine needs many experts for a few years: monitors, data staff, safety experts, statisticians and writers. Hiring all of them is costly. So the sponsor (the firm that owns the product) hires a contract research organization (CRO) to do some or all of the work.
The global trial rulebook, ICH-GCP, says a CRO does trial tasks for the sponsor under a contract. The 2025 version, ICH E6(R3), uses a wider term, service provider. It also covers labs, scan centres and other vendors. Either way, the sponsor can hand over tasks but stays responsible for patient safety and good data.

Types of CROs
- Full-service CROs — run whole trials across many countries (e.g. IQVIA, ICON, Parexel, Syneos Health, Fortrea, Thermo Fisher’s PPD, Medpace).
- Functional service providers (FSPs) — supply teams for one function, such as data management, safety or programming.
- Niche or specialist CROs — focus on one area, such as oncology, devices, or bioavailability/bioequivalence (BA/BE) studies.
- Indian CROs — include BA/BE and clinical CROs such as Veeda Clinical Research, Lambda Therapeutic Research and Cliantha Research, and research services firms like Syngene.
New rules for contract research organizations in India
Until recently, India had no separate rules for CROs. Their names only had to appear in the trial plan. In September 2024, the Health Ministry changed the New Drugs and Clinical Trials Rules, 2019 and added a chapter on CROs.

Definition
A CRO is a body to which a sponsor delegates trial or BA/BE study tasks.

FAQs
What is a contract research organization?
A company hired by a pharma, biotech or device sponsor to run some or all of its clinical research tasks, such as monitoring, data management, drug safety, statistics and regulatory work.
What is the difference between a CRO and an SMO?
A CRO works for the sponsor and runs trial tasks across many sites. An SMO works with hospitals and investigators to help run the trial at the site, usually providing CRCs.
Do CROs need registration in India?
Yes. Under the 2024 amendment to the NDCT Rules, 2019, CROs must register with CDSCO’s Central Licensing Authority (Form CT-07B) from 1 April 2025. Registration is valid for five years.
Is the sponsor still responsible if a CRO runs the trial?
Yes. Under ICH-GCP the sponsor can delegate tasks but keeps overall responsibility for participant safety and data reliability, and must oversee the CRO.
Which CROs operate in India?
Global CROs such as IQVIA, ICON, Parexel, Syneos Health, Fortrea and Thermo Fisher (PPD), and Indian CROs such as Veeda Clinical Research, Lambda Therapeutic Research and Cliantha Research.
How do I get a job in a CRO?
Build the basics (ICH-GCP, trial documents, EDC or safety tools) through a focused course, then apply for CTA, CRA-trainee, data coordinator or drug safety roles. Freshers often start in data or safety teams.
