Types of Clinical Trials – Based on Investigational Product.

Investigational Product

A pharmaceutical form of an active ingredient or placebo being tested or used as a reference in a clinical trial, including a product with a marketing authorization when used or assembled (formulated or packaged) in a way  different from the approved form, or when used for an unapproved indication, or when used to gain further  information about an approved use.

In simple terms – Investigational Product or IP is the medicine/treatment on which a clinical trial is conducted. Based on what Investigational Product is used, clinical trials can be classified as follows.


Chemical Entity Clinical Trials.

These are clinical trials conducted on Allopathy medicines. Chemical Entities can be NCE (New Chemical Entity) which means a newly discovered Allopathy medicine. They can also be FDC (Fixed Dose Combination) i.e. combinations of various drugs in one tablet – multiaction tablets.


Medical Devices Clinical Trials.

As per CDSCO, Medical Devices can be classified as follows based on risk.

Class A: Low Risk: Eg: Thermometers, Tongue depressors.

Class B: Low-Moderate Risk: Eg: Hypodermic needles.
