A Study of Ifinatamab Deruxtecan for Relapsed Small Cell Lung Cancer

This study is testing a drug called Ifinatamab deruxtecan (I-DXd) for people with small cell lung cancer (SCLC) that has come back (relapsed). It compares I-DXd to treatments your doctor might typically choose, such as Topotecan, Amrubicin, or Lurbinectedin. The main goals are to see if I-DXd can shrink tumors (objective response rate) and help people live longer (overall survival) over about 5 years. Adults aged 18 and older can join. The study is currently unclear on its status and plans to enroll 540 participants.

Study design
This interventional study plans to enroll 540 participants. It compares Ifinatamab deruxtecan to other standard treatments for relapsed small cell lung cancer.
What's involved
You would receive Ifinatamab deruxtecan intravenously (into a vein) on Day 1 of each 21-day cycle, or one of the standard treatments as decided by your doctor. Your tumor response and survival will be measured for up to approximately 5 years.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed from the date of randomization to the date of death due to any cause, up to approximately 5 years.

    OS is defined as the time interval from the date of randomization to the date of death due to any cause.
