Safety and Efficacy of Loco-regional B7H3 IL-7Ra CAR T Cell in DIPG

Korábbi kezelés

• Serologic status reflecting active HIV, hepatitis B or C infection. Participants who are positive for hepatitis B core antibody, hepatitis B surface antigen or hepatitis C antibody must have negative PCR prior to enrollment.

Más betegség

• Presence of \>= grade 3 cardiac dysfunction or symptomatic arrythmia requiring intervention
• Presence of primary immunodeficiency or bone marrow failure syndrome
• History of active malignancy other than nonmelanoma skin cancer and carcinoma in situ (e.g., cervix, bladder, breast).
• Presence of uncontrolled intercurrent illness including but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, pulmonary abnormalities, or psychiatric illness/social situations that would limit compliance with study requirements.

Laborértékek

• Pregnant or breastfeeding women were excluded from this study because CAR-T-cell therapy may be associated with the potential for teratogenic or abortifacient effects. Women of childbearing potential must have a negative serum pregnancy test. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with CAR-T cells, breastfeeding should be discontinued. These potential risks may also apply to other agents used in this study. Participants of childbearing or child-fathering potential must be willing to practice birth control from the time of enrollment in this study and for four months after receiving CAR-T-cell infusion.
