Pediatric Initiatives • Pediatric Research Equity Act, December 3, 2003 • Best Pharmaceuticals for Children Act, January 4, 2002 Both laws are intended to support and encourage drug development in the pediatric population
PREA studies are mandatory • BPCA studies are voluntary
Why Both PREA and BPCA? • Distinction between the scope of studies requested under BPCA and required under PREA • PREA specific to indication in submission • BPCA can ask for “off-label” indications • Sildenafil Citrate (Viagra) • Pediatric studies required by the Pediatric Rule were waived • Written Request was issued
Pediatric Research Equity Act (PREA) • Became law December 3, 2003 • PREA is the codification of the 1998 Pediatric Rule • Drugs and Biologics affected • Not applicable to drugs with Orphan Designation
PREA • One of two laws intended to promote the study of drugs and biologics in pediatric patients • Studies prevent pediatric patients from being a “study of one” • Studies in the pediatric population are REQUIRED, but only for the indication that was studied in adults
PREA • Pediatric Assessment required for certain applications unless waived or deferred • Draft Guidance recently issued (9/7/05)
PREA • Pediatric Assessment contains • data adequate to assess the safety and effectiveness of the drug or biological product, and • data to support dosing and administration for each pediatric subpopulation
PREA • Assessment required for applications: • New ingredient • New indication • New dosage form • New dosing regimen • New route of administration
Full Waiver Waiver granted when: • Necessary studies impossible or highly impracticable; • Strong evidence suggests the drug or biologic would be ineffective or unsafe; or • Product does not represent a meaningful therapeutic benefit over existing therapies AND is not likely to be used in a substantial number of pediatric patients
“Substantial Number” • PREA does not define substantial number • FDA generally has considered 50,000 patients to be a substantial number • FDA will take into consideration the nature and severity of the condition when making this determination
Partial Waiver Partial Waiver is a special waiver for a pediatric age group (i.e. less than 6 months of age) and is granted when: • The criteria for a full waiver applies to that age group; or • Reasonable attempts to produce a pediatric formulation necessary for that age group have failed
Full and Partial Waiver Labeling Requirement: • If full or partial waiver is granted because there is evidence that the drug or biologic would be ineffective or unsafe, that information must be included in the label
Deferral • A deferral is granted when a pediatric assessment is needed, but permits submission of the pediatric assessment after submission of NDA/BLA • Reasons for deferral • Drug or biologic is ready for approval in adults; • Need additional safety data; or • There is another appropriate reason for deferral
PREA • Not as flexible as BPCA • Indications for required pediatric studies are limited to the indications in a given submission • An assessment would be waived under PREA in submissions for the treatment of a condition that occurs only in adults • Prostate, breast cancer
Best Pharmaceuticals for Children Act (BPCA) • Became law January 4, 2002 • Renewed authority (FDAMA) to grant six months of marketing exclusivity to Sponsors who conduct and submit studies in response to a Written Request. • Includes an additional mechanism for obtaining information for the use of off-patent drugs in pediatric patients
Goal • The goal of both PREA and BPCA: • Obtain information from studies about the use of medications in the pediatric population. • Obtain studies for both common and rare conditions. • Disseminate information about the safe and efficacious use of medications in children.
PREA vs. BPCA PREA • Studies mandatory • Required studies only on drug/indication under review • Studies for orphan indications not required • Applies to drugs and biologics • Sunsets October 1, 2007 BPCA • Studies voluntary • Studies on entire active moiety • WR may be issued for orphan indications • Applies only to drugs • Sunsets October 1, 2007
