Idiotypic vaccination has already proved capable (in responding patients) of: biological efficacy, that is the capacity of inducing an idiotype- and tumor-specific immune response (Kwak LW et al. NEJM 1992); clinical efficacy, that is the capacity of inducing specific immune responses able to kill in vivo follicular lymphoma cells that had survived pre-vaccine chemotherapy (Bendandi M et al. Nature Med 1999): clinical benefit, that is the capacity of prolonging survival of responding patients (Inoges et al. JNCI 2006). Now, we want to test whether it is also capable of contributing to the ultimate goal of preventing relapse indefinitely in responding patients.
