Preguntas frecuentes
- Que es Complete Response Letter?
- Carta oficial de FDA comunicando que la aplicacion no puede aprobarse en su estado actual. Detalla las deficiencias que deben corregirse. El sponsor puede responder con datos adicionales, solicitar meeting, o retirar la aplicacion. Es practicamente un rechazo que puede reversarse.
- Cual es la diferencia entre NDA y BLA?
- NDA (New Drug Application) para small molecules y algunos peptidos pequenos. BLA (Biologics License Application) para biologicos, incluyendo mayoria de peptidos terapeuticos. BLA tiene requerimientos adicionales de manufacturing, facility licensing, y no tiene generic pathway (solo biosimilar).
- Que es REMS?
- Risk Evaluation and Mitigation Strategy. Plan requerido por FDA cuando los controles normales son insuficientes para asegurar uso seguro. Puede incluir: medication guide, communication plan, elementos para asegurar uso seguro (certificacion de prescriptores, registro de pacientes, farmacias certificadas).
- Como se determina si un peptido es NDA o BLA?
- No hay regla absoluta. Factores: tamano (aprox. 40 aminoacidos es referencia), complejidad, metodo de manufactura. Peptidos sinteticos pequenos a menudo NDA. Peptidos mas grandes, producidos recombinantemente, o con modificaciones complejas tipicamente BLA. Consultar con FDA para determinacion oficial.
