Overview
The duration of the study for a participant will include:
* Screening Period: up to 28 days
* Treatment Period: enrolled and exposed participants will receive continuous treatment until progressive disease (PD), or an occurrence of an unacceptable AE, a withdrawal of consent, or until other permanent discontinuation criteria described in the protocol are met.
The End of Treatment (EOT) visit will occur 30 days ±7 days from the last IMP administration or prior to the initiation of further therapy, whichever occurs first.
The follow-up period will occur until disease progression, the start of new anticancer therapy, death, or withdrawal of participant's consent, whichever comes first.
