The Food and Drug Administration (FDA or Agency) is announcing the availability of recommendations for a new permitted daily exposure (PDE) for the residual solvent triethylamine and a revised PDE for the residual solvent methylisobutylketone. The PDEs were developed according to the methods for establishing exposure limits included in the guidance for industry entitled ``Q3C Impurities: Residual Solvents.'' The recommendations were prepared under the auspices of the International Council for Harmonisation (ICH), formerly the International Conference on Harmonisation. The document is intended to recommend acceptable amounts for the listed residual solvents in pharmaceuticals for the safety of the patient.

SUPPLEMENTARY INFORMATION:

I. Background

    In recent years, many important initiatives have been undertaken by 
regulatory authorities and industry associations to promote 
international harmonization of regulatory requirements. FDA has 
participated in many meetings designed to enhance harmonization and is 
committed to seeking scientifically based harmonized technical 
procedures for pharmaceutical

[[Page 34538]]

development. One of the goals of harmonization is to identify and then 
reduce differences in technical requirements for drug development among 
regulatory agencies.
    ICH was organized to provide an opportunity for harmonization 
initiatives to be developed with input from both regulatory and 
industry representatives. FDA also seeks input from consumer 
representatives and others. ICH is concerned with harmonization of 
technical requirements for the registration of pharmaceutical products 
for human use among regulators around the world. The six founding 
members of the ICH are: The European Commission; the European 
Federation of Pharmaceutical Industries Associations; the Japanese 
Ministry of Health, Labour, and Welfare; the Japanese Pharmaceutical 
Manufacturers Association; CDER and CBER, FDA; and the Pharmaceutical 
Research and Manufacturers of America. The Standing Members of the ICH 
Association include Health Canada and Swissmedic. Any party eligible as 
a Member in accordance with the ICH Articles of Association can apply 
for membership in writing to the ICH Secretariat. The ICH Secretariat, 
which coordinates the preparation of documentation, operates as an 
international nonprofit organization and is funded by the Members of 
the ICH Association. The ICH Assembly is the overarching body of the 
Association and includes representatives from each of the ICH members 
and observers.
    In the Federal Register of December 24, 1997 (62 FR 67377), FDA 
published a notice announcing the availability of the ICH guidance for 
industry entitled ``Q3C Impurities: Residual Solvents.'' The guidance 
makes recommendations as to what amounts of residual solvents are 
considered toxicologically acceptable for some residual solvents. Upon 
issuance in 1997, the text and appendix 1 of the guidance contained 
several tables and a list of solvents categorizing residual solvents by 
toxicity, classes 1 through 3, with class 1 being the most toxic. The 
ICH Quality Expert Working Group (EWG) agreed that the PDE could be 
modified if reliable and more relevant toxicity data were brought to 
the attention of the group and the modified PDE could result in a 
revision of the tables and list.
    In 1999, ICH instituted a Q3C maintenance agreement and formed a 
maintenance EWG (Q3C EWG). The agreement provided for the revisitation 
of solvent PDEs and allowed for minor changes to the tables and list 
that include the existing PDEs. The agreement also provided for new 
solvents and PDEs that could be added to the tables and list based on 
adequate toxicity data. In the Federal Register of February 12, 2002 
(67 FR 6542), FDA briefly described the process for proposing future 
revisions to the PDE. In the same notice, the Agency announced its 
decision to delink the tables and list from the Q3C guidance and create 
a stand-alone document entitled ``Q3C: Tables and List'' to facilitate 
making changes recommended by ICH, available at https://www.fda.gov/downloads/drugs/guidancecomplianceregulatoryinformation/guidances/ucm073395.pdf. The ``Q3C: Tables and List'' has been updated as of 
January 2017 to include the recommended PDE for triethylamine and 
methylisobutylketone.
    In the Federal Register of October 16, 2015 (80 FR 62537), FDA 
published a notice announcing the availability of draft recommendations 
for the PDEs for two solvents, trimethylamine and methylisobutylketone, 
according to the maintenance procedures for the guidance entitled ``Q3C 
Impurities: Residual Solvents,'' available at https://www.fda.gov/ucm/groups/fdagov-public/@fdagov-drugs-gen/documents/document/ucm073394.pdf. The notice gave interested persons an opportunity to 
submit comments by December 15, 2015. After consideration of the 
comments received and revisions to the guidance, a final draft of the 
recommendations was submitted to the ICH Assembly and endorsed by the 
regulatory agencies in November 2016.
    The guidance provides a new PDE for the solvent trimethylamine and 
a revised PDE for the solvent methylisobutylketone. In addition, the 
data used to derive the PDEs are summarized. Revisions made to the 
final guidance as a result of comments include a modification of the 
PDE for methylisobutylketone from 22.6 milligrams (mg)/day to 45 mg/day 
based on reconsideration of the severity of effects identified in rat 
studies and the human relevance of effects identified in mouse 
carcinogenicity study. The recommendation to place methylisobutylketone 
into class 2 remains. The ``Q3C: Tables and List'' has been updated as 
of January 2017 to include the recommended PDE for triethylamine and 
methylisobutylketone.
    This guidance is being issued consistent with FDA's good guidance 
practices regulation (21 CFR 10.115). The guidance represents the 
current thinking of FDA on ``Q3C Impurities: Residual Solvents.'' It 
does not establish any rights for any person and is not binding on FDA 
or the public. You can use an alternative approach if it satisfies the 
requirements of the applicable statutes and regulations.
