Improving Regulatory Transparency for New Medical Therapies Act - Amends the Controlled Substances Act to require any proceedings for the issuance, amendment, or repeal of a rule of the Attorney General for the classification of a controlled substance that are initiated at the request of the Secretary of Health and Human Services (HHS) to control a drug or other substance not previously scheduled, where the Secretary has recommended the drug or other substance be placed in schedule II, III, IV, or V, to be commenced not later than 120 days after receipt of written recommendations from the Secretary. Requires the final rule to be issued not later than 60 days after the date on which both the public comment period has closed and the new drug is the subject of an approved new drug application, unless a hearing on the proposed rule is granted by the Attorney General.
