FAQ
Frequently asked questions
What is comparator sourcing?
Comparator sourcing is the procurement of reference-listed drugs (RLDs) and active comparators used as the benchmark treatment in a clinical trial. GNH USA sources these direct from innovators and OEMs, with full chain-of-custody documentation.
Can GNH USA source comparators from Rest-of-World (RoW) and emerging markets?
Yes. We source comparators from regulator-approved markets worldwide, including RoW and emerging markets. This can significantly reduce the cost of trial supply while maintaining equivalence and full documentation.
Do you supply biologics and biosimilar reference products?
Yes. Our comparator supply covers small molecules, biologics and biosimilar reference products, as well as rescue medication, co-medication and analytical samples.
How is product integrity maintained during shipping?
Every comparator ships through a WHO GDP-compliant supply chain, with validated cold-chain packaging where required and a full source-to-site audit trail.
How do I request a comparator sourcing quote?
Send a sourcing enquiry with the molecule, strength, form, pack size and quantity you need. GNH USA will respond with availability, lead time and pricing.
