Why this matters
Some study products are controlled drugs. Others are cytotoxics, or biologics needing ultra-cold storage, or radiopharmaceuticals.
For these, national law sits alongside the protocol. Where they differ, the law wins.
Two sets of requirements, both mandatory
The protocol and pharmacy manual describe study handling. National rules describe storage, registers, witnessing and destruction.
You comply with both. A protocol cannot reduce a legal duty. A legal duty does not excuse a protocol one.
Where they conflict, take the stricter one. Then confirm with the sponsor in writing.
Controlled drug registers
Most countries require a bound register. Entries run in sequence. A witness is often needed for destruction.
The register is separate from the accountability log. Both are kept. They must agree. Where they do not, it is a finding under two sets of rules at once.
Never complete a register entry in advance.
Cytotoxic and hazardous preparation
The preparation area, protective equipment, spill steps and waste route are all specified. None is optional for study product.
A dose prepared outside the required area is a deviation. It is also a staff safety issue.
Ultra-cold and specialized storage
Products needing minus seventy storage need monitored freezers. They also need a backup and a written plan for failure.
Know what happens if that freezer fails on a Saturday. If the answer is not written down and rehearsed, it does not exist.
In practice
National law requires witnessed destruction of a controlled study drug. The sponsor requires return instead.
You return it. You record the return in both the register and the accountability log. The witness the law requires signs for the movement.
Satisfying one requirement is not satisfying both.
What this looks like when it goes wrong
A site follows study procedures only. It keeps no national register, because the product is investigational.
A pharmacy inspection finds no register. The finding is regulatory rather than study-related. It affects the site's license, not just the trial.
Key takeaways
- Protocol and national law both apply; the stricter usually governs.
- Keep the controlled drug register and the accountability log, and keep them agreeing.
- Preparation environment requirements are not negotiable for study product.
- Have a written, rehearsed plan for specialized storage failure.
