Clinical Trial Registration
In cell therapy, we are currently investigating multiple indications in the axicabtagene ciloleucel and the KTE-C19 development program as well as for our TCR pipeline and second-generation technology. Our areas of research include a variety of blood cancers and solid tumors.
Gilead ensures that applicable clinical trials are registered prior to the first patient being consented for the study. Registration prior to first patient consent is aligned with the International Committee of Medical Journal Editors (ICMJE) guidelines.
