Colombia-Made CAR-T cells put to the test against stubborn blood cancers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Recent Major Surgery: Major surgery within the last 4 weeks prior to lymphodepletion. 9. Prior Malignancies: History of cancer within the last two years prior to screening, except for appropriately locally treated malignancies considered in complete remission with minimal risk of requiring systemic therapy during the study (squamous or basal cell skin cancer, breast carcinoma, bladder carcinoma, cervical carcinoma in situ, low-grade prostate cancer Gleason \\\<= 6). 10.

Metabolic / Renal: Poorly controlled diabetes mellitus despite adequate therapy; acute kidney disease requiring dialysis. Other Safety Contraindications: Any condition that, in the principal investigator's judgment, contraindicates participation due to safety or protocol compliance concerns. 15. Active Infectious Diseases: Active infections including tuberculosis, active hepatitis B (positive viral load), hepatitis C (positive viral load), or HIV seropositivity. 16. Cognitive / Psychiatric Conditions: Medical, psychiatric, or cognitive conditions that compromise the subject's capacity to understand information, make autonomous decisions, sign informed consent, or adhere to protocol requirements. 17.
