FDA defines ‘controlled correspondence’ as ‘correspondence submitted to the agency, by or on behalf of a generic drug manufacturer or related industry, requesting information on a specific element of generic drug development.’ The agency adds that ‘controlled correspondence does not include citizen petitions, petitions for reconsideration, or requests for stay.’

The agency has also agreed to set certain goals for the timelines within which it will respond to requests. These include that:

• FDA will respond to 70% of controlled correspondence within 4 months from the date of submission in fiscal year (FY) 2015
• FDA will respond to 70% of controlled correspondence within 2 months from the date of submission in FY 2016
• FDA will respond to 90% of controlled correspondence within 2 months from the date of submission in FY 2017
• If the controlled correspondence requires input from the clinical division, one additional month will be added to the goals outlined above
