INN 64th Executive Summary

64th Consultation on International Nonproprietary Names

9 July 2017

| Publication

During the 64th INN Consultation, a total of 161 INN requests were discussed, including:

109 new INN requests, including 55 for biological substances
49 outstanding requests
3 previously selected proposed/recommended INN, against which a formal objection or a request of substitution had been raised.

As a result of these discussions, 149 names were selected, which are planned to be published in

List 118 of Proposed INNs (p.INN), while 2 requests were deferred for future discussion. Two

applications were planned to be closed if the requested information is not received on time for review

at the next INN Consultation. Four requests were rejected by the INN Expert Group, as the

substances did not conform to the criteria for INN selection. One INN application already had a

published Recommended INN and two applications were withdrawn. One amendment was planned to

be published in a forthcoming List of p.INN and one request of substitution could not be retained as it

did not conform to the criteria. Four new stems/substems were selected, 6 suffixes were promoted to

the pre-stem list and it was decided to amend the descriptions of two stems.
