Roll-Over Study of Alpelisib (BYL719) for Continued Access and Long-Term Safety.

Официальное название

An Open Label, Multi-center Alpelisib Roll-over Study to Assess Long-term Safety in Participants Who Have Completed a Novartis Sponsored Alpelisib (BYL719) Study and Are Judged by the Investigator to Benefit From Continued Treatment With Alpelisib.

Обзор

The purpose of this study is to provide post-trial access to alpelisib and to assess its long-term safety when administered as a single agent or in combination with other drugs. This study is intended for participants who are currently receiving alpelisib in a Novartis-sponsored clinical trial (parent study) and, in the Investigator's judgment, would benefit from continued treatment with alpelisib.

Подробное описание

Eligible participants are those who are receiving alpelisib, either as a single agent or in combination with other drugs, at the end of one of the following parent studies: CBYL719F12401 (NCT04980833), CBYL719G12301 (NCT04208178), CBYL719C2303 (NCT05038735), CBYL719C1201 (NCT04524000), CBYL719C2201 (NCT04544189), or CLEE011X2107 (NCT01872260).

Participants transition directly from the parent study into this roll-over study without a separate screening period. At enrollment, participants continue treatment with the same combination and the same dose that were administered at the end of the parent study. Study visits, treatment administration, and safety assessments generally follow the schedules used in the parent study.

Participants continue receiving alpelisib until clinical benefit is no longer observed, study treatment is discontinued for safety or other protocol-defined reasons, or another discontinuation criterion is met. Clinical benefit is evaluated by the investigator at scheduled visits.

Safety is monitored throughout the study through the collection of adverse events and serious adverse events. Safety assessments are conducted at regular intervals during treatment in accordance with the study protocol and local clinical practice.

At discontinuation of study treatment, participants complete an end-of-treatment visit. All participants are followed for safety for 30 days after the last dose of alpelisib.
