A test of a new medicine in people is called a clinical trial. Every step must be recorded to the standard a drug regulator demands:
- who was enrolled in the trial
- which patients got the medicine, and which got a dummy, decided at random so the comparison is fair
- what dose each patient received, and when
- what happened to each patient, including what patients report themselves
The software that records all this, assigns the patients at random, ships the medicine to each hospital and collects what patients report is a large industry. Much of it is built in India. India also does a large share of the world's work on trial data and its statistics, called biostatistics. The buyers are drug companies, and the firms that run trials for them.
This Market Segment covers the software. The firms that run trials for drug companies, with their own software, are covered in Market Segment 25.4, Contract research organisations (CROs).
Every company named here has posted software engineering jobs in India. Famous companies that don't actively hire software engineers in India are left out.

Back to the trial of the skin cream from the start of this Market Segment. Its data comes from 200 hospitals, and must end up in one place, clean and checked.

What happens to each patient
Designing the trial
Three companies covered mainly in other Market Segments are here too:
The slowest part of most trials is finding patients who qualify. AI models now read hospitals' records to find them. They also draft the trial's plan, called the protocol, and its changes, and clean the trial's data as it arrives. Regulators are writing the rules for AI in trials, while the industry is already adopting it.
