The Committee for Medicinal Products for Human Use adopted a positive opinion recommending a variation to the marketing authorization for the drug Zytiga. The new indication is for the treatment of metastatic castration-resistant prostate cancer in asymptomatic or mildly symptomatic men after failure of androgen deprivation therapy when chemotherapy is not yet clinically indicated. A new contraindication of severe hepatic impairment was also adopted. Detailed conditions of use will be described in updated product information published after European Commission approval of the variation.
