A Roll Over Study of Alectinib in Patients With Anaplastic Lymphoma Kinase (ALK)-Positive or Rearranged During Transfection (RET)-Positive Cancer

The purpose of this study is to provide continued treatment with alectinib or crizotinib as applicable to participants with ALK- or RET positive cancer who were previously enrolled in any Roche-sponsored alectinib study and who are deriving continued clinical benefit from alectinib or crizotinib in the parent trial at the time of parent trial closure.
