| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| •	Evidencia de documento de consentimiento informado firmado y fechado personalmente, indicando que el paciente ha sido informado de todos los aspectos pertinentes del ensayo. •	Paciente que al menos haya recibido una dosis de fármaco de estudio y haya finalizado su participación en algún estudio controlado y aleatorizado de Fase 2B o 3 o un estudio abierto (estudio de calificación) de CP-690,550 para el tratamiento de la AR.

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| •	Episodios de trastorno linfoproliferativo (TLP) confirmado por el patólogo local. •	Episodios de linfoma confirmado por el patólogo local.
 •	Episodios de trastorno linfoproliferativo (TLP) confirmado por el patólogo central.
 •	Episodios de linfoma confirmado por el patólogo central.
 •	Episodios de infección importante, definida como infección grave u oportunista.

Un ejemplo de infección oportunista que no se calificaría de grave sería una candidiasis esofágica tratada ambulatoriamente con medicación oral.
 •	Estado funcional evaluado mediante la puntuación del Cuestionario de Valoración de la Salud –Índice de Incapacidad (HAQ DI).
