- Patients must have a site of disease amenable to biopsy, and be a candidate for tumor biopsy. Patient must be willing to undergo a new tumor biopsy at baseline or at molecular pre-screening if applicable, and during therapy on this study. For patients in the phase II part of the study, exceptions may be granted after documented discussion with Novartis. After a sufficient number of paired biopsies are collected, the decision may be taken to stop the collection of biopsies.
