This clinical trial is focused on studying treatments for people with advanced cancers and certain immune system diseases. The study involves a medication called parsaclisib, which is being tested either on its own or in combination with other treatments. These additional treatments include itacitinib, ruxolitinib, ibrutinib, and tafasitamab. The purpose of the study is to continue providing treatment and to monitor the safety of these medications in participants who have been part of previous studies involving parsaclisib.
Participants in this study will continue to receive their treatment as they have been, and the study will observe how they respond to the medication over time. The study will not introduce any new treatments but will focus on maintaining the current treatment regimen. The study aims to ensure that participants continue to benefit from the treatment and to gather information on any side effects they may experience.
The study is designed to be open-label, meaning that both the participants and the researchers know which treatments are being administered. This approach helps in closely monitoring the effects of the treatment and ensuring the safety of the participants. The study will continue until the estimated end date, allowing researchers to collect comprehensive data on the long-term effects and safety of the treatments being studied.
