# Withdrawal of Approval of 128 Suitability Petitions
**AGENCY:**
Food and Drug Administration, HHS.
**ACTION:**
Notice.
**SUMMARY:**
The Food and Drug Administration (FDA) is withdrawing approval of 128 suitability petitions. This action is being taken in accordance with the Pediatric Research Equity Act of 2003 (PREA). Prior to PREA's enactment, FDA had approved these suitability petitions to permit abbreviated new drug applications (ANDAs) to be submitted for drugs that had a different active ingredient, dosage form, or route of administration than their reference listed drugs (RLDs). However, these approval decisions are being withdrawn because ANDAs were never submitted and PREA requires that all applications submitted on or after April 1, 1999, for a new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration contain an assessment of the safety and effectiveness of the drug for the claimed indications in relevant pediatric subpopulations unless the requirement is waived or deferred. This action is being taken without prejudice. Any of the suitability petitions may be resubmitted for action by the agency in accordance with current law.
**DATES:**
This notice is effective March 26, 2007.

**SUPPLEMENTARY INFORMATION:**
PREA (Public Law 108-155) was enacted on December 3, 2003. Among other things, section 2 of PREA requires that all drug applications submitted on or after April 1, 1999, for a new active ingredient, new indication, new dosage form, new dosing regimen, or new route of administration contain an assessment of the safety and effectiveness of the drug for the claimed indications in relevant pediatric subpopulations unless the requirement is waived or deferred. As a result, FDA is withdrawing its approval for 128 suitability petitions for which ANDAS were never submitted. The approval decisions, made prior to the enactment of PREA, would have permitted ANDAs to be submitted for certain drugs that have a different active ingredient, dosage form, or route of administration than their RLDs. No ANDAs were submitted for these drugs pursuant to these suitability petitions prior to April 1, 1999, and any such application submitted on or after April 1, 1999, would be required to contain the safety and effectiveness assessments required by PREA, unless waived or deferred. According to § 314.93(e)(1)(i) (21 CFR 314.93(e)(1)(i)), a suitability petition may not be approved if investigations must be conducted to show the safety and effectiveness of the drug product. In addition, according to § 314.93(f), FDA may withdraw approval of a suitability petition if it receives information demonstrating that the petition no longer satisfies the conditions of § 314.93(e). Under PREA, safety and effectiveness investigations in pediatric subpopulations would be required for the drug products proposed by these suitability petitions, unless the requirement is waived or deferred. Therefore, these suitability petitions no longer satisfy the regulatory requirements for approval. Pursuant to § 314.93(f), FDA is withdrawing approval of the 128 suitability petitions listed in the following table:
