Anaplastic Lymphoma Kinase

The researchers are doing this study to see if alectinib in combination with duvelisib is a safe and effective time-limited treatment for people with relapsed or refractory ALK+ anaplastic large cell lymphoma (ALCL). The researchers will test different doses of the study drugs to find the highest doses that cause few or mild side effects in participants. Once they find this dose combination, they will test it in a new group of participants to learn how long the effect of the combination lasts after the end of treatment

The purpose of this study is to estimate the proportion of all adverse events (AEs) including serious adverse events (SAEs) occurring with the use of brigatinib among adult participants who have been administered brigatinib as per the approved indications.
