History or evidence of active tuberculosis (TB) 7. Any uncontrolled medical illness or unstable treatment ot therapy. |
1. Antecedentes de reacción alérgica o sensibilidad importante a cualquier componente del fármaco del estudio, de reacción anafiláctica a cualquier producto (p. ej., alimentos o picaduras de abeja) o de una reacción importante a cualquier producto que contenga IgG. 2.
