Raffaele Colombo: International Nonproprietary Names Proposed List 133 Is Out

Raffaele Colombo, Associate Director of Medicinal Chemistry at Zymeworks, shared a post on X:

“INN Proposed List 133 is out!

Here are the International Nonproprietary Names (INN) for ADCs, along with their targets, payloads, and development codes.

These new names just keep getting easier and easier.

Can’t wait to casually drop lixarkitug samrotecan into conversation!

There are a lot of interesting nuances in those names and structures!

Of note, there are no sponsors’ names in the document, so it is always a puzzle to try to combine INNs with each ADC.

99% confidence level.”
