You may experience side effects from JEMPERLI

JEMPERLI is a medicine that may treat certain cancers by working with your immune system. JEMPERLI can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.

In study participants receiving JEMPERLI + carboplatin and paclitaxel (CP), 19% stopped taking JEMPERLI completely and 37% had their treatment interrupted due to side effects.
