Frequently asked questions about INT2104

What is INT2104 used for?

INT2104 is an investigational gene therapy being studied in adults with B-cell cancers, including non-Hodgkin's B-cell lymphomas and precursor cell lymphoblastic leukemia-lymphoma, that have returned after previous treatment. It is not yet approved for any indication and remains in clinical development.

Who is developing INT2104?

INT2104 is being developed by Gilead Sciences, Inc., which trades on Nasdaq under the ticker GILD. The company is the sponsor of the clinical program evaluating the gene therapy in patients with relapsed B-cell malignancies.

What phase is INT2104 in?

INT2104 is in Phase 1 clinical development. The program has one active trial, and no trials have been completed. The Phase 1 study is designed to investigate the safety of INT2104 infusions in participants aged 18 years and older with B-cell cancers that came back after previous treatment.

What clinical trial is INT2104 in?

INT2104 is being evaluated in the Phase 1 trial NCT06539338, titled a study to investigate safety of INT2104 infusions in participants aged 18 years of age and older who have B-cell cancers that came back after previous treatment. The trial is active but not recruiting, with an estimated enrollment of 10 participants across Australia and Spain.

Is INT2104 FDA approved?

No. INT2104 is an investigational gene therapy and has not been approved by the FDA. It is currently in Phase 1 clinical testing for relapsed B-cell cancers, including non-Hodgkin's B-cell lymphomas, and remains under study for safety and tolerability.
