A Complete Guide to NDCT Rules, 2019 for Clinical Trials in India

India’s regulatory landscape for clinical trials underwent a major transformation with the introduction of the New Drugs and Clinical Trials (NDCT) Rules, 2019. Implemented by the Central Drugs Standard Control Organization (CDSCO), these rules provide a streamlined, transparent, and well-defined framework for the conduct of clinical trials, ethics approval, safety monitoring, and marketing authorisation of new drugs. This tutorial offers an in-depth overview of the NDCT Rules, helping sponsors, investigators, and regulatory professionals comply effectively with Indian clinical research regulations.

What Are NDCT Rules, 2019?

The NDCT Rules, 2019 replaced the previous patchwork of notifications and guidelines with a unified rule set under the Drugs and Cosmetics Act, 1940. Their goal is to promote ethical research, protect trial participants, and expedite drug development through regulatory clarity and global alignment.

Applicability of NDCT Rules:

• All new drug and investigational new drug applications
• Bioavailability and bioequivalence (BA/BE) studies
• Clinical trials conducted in India
• Ethics committee registration and oversight
• Manufacture or import of investigational products

Classification of Clinical Trials:

Clinical trials under the NDCT Rules are divided into phases similar to international guidelines:

• Phase I: First-in-human studies assessing safety and dosage
• Phase II: Efficacy and side-effect evaluation in patients
• Phase III: Large-scale testing for effectiveness and adverse reactions
• Phase IV: Post-marketing surveillance and risk assessment

Key Stakeholders and Responsibilities:

1. Sponsors: Must submit applications through SUGAM portal and ensure GCP compliance, insurance coverage, compensation, and periodic reporting.
