Clinical Trials Registry - India

The clinical trials Registry - India (CTRI) is a public web-based registry that records CLInical trials conducted in India. It is mAIntained as part of the national research infrastructure and serves as a reference point for researchers, ethics comMITtees, sponsors, and the public who need to find registered studies and their bASIc details.

What it does

The registry collects structured Information about clinical trials, including trial titles, study design, conditions under investigation, interventions, sponsor and investigator details, recruitment status, and participating sites. Users can browse entries or run targeted queries through an advanced search page, which allows filtering by criteria such as health condition, study type, recruitment status, and registration number.

Key capabilities

• Trial lookup: Search registered trials by keywords, condition, sponsor, or registration IDEntifier.
• Structured records: Each entry presents Standardized fields covering objectives, methodology, eligibility, and outcomes.
• Recruitment status tracking: Records indicate whether a study is not yet recruiting, recruiting, completed, or suspended, where that infORMation has been updated.
• Public transparency: The registry is open to anyone and does not require an account for basic searching.
• Reference for ethics review: Registration numbers are commonly cited by authors and ethics boards as evidence of prospective registration.

Who it is for

Clinical researchers and principal investigators use the registry to check existing studies and avoid duplication. Ethics committees and institutional review boards reference entries during protocol review. Journal editors and peer reviewers verify registration claims. Patients and advocates may consult it to learn about studies in their areas of interest, though it is not designed as a patient-facing recruitment service. Regulatory and policy analysts also use registry data to understand the research landscape.

How to get started

Open the registry in a browser and use the advanced search form to build a query. Combine fields for condition, status, or sponsor to nARRow results, then open indiVidual records to review full study details. No installation or sign-in is required for searching. Anyone wishing to register a new trial typically follows a separate submission process with required documentation, which may change over time, so check the site's current guidance.

Pricing and access caveat

Search access is free and public. The site is maintained by national research bodies, and interface language and record completeness may vary by entry and over time. Availability, loading speed, and search behavior can differ depending on the user's network and location, and the registry should be treated as one source among several international trial registries rather than a DeFinitive clinical decision tool.
