⛔ FDA Black Box Warning

WARNING: HEPATOTOXICITY, INCLUDING HEPATIC VENO-OCCLUSIVE DISEASE (VOD) (ALSO KNOWN AS SINUSOIDAL OBSTRUCTION SYNDROME) and INCREASED RISK OF POST-HEMATOPOIETIC STEM CELL TRANSPLANT (HSCT) NON-RELAPSE MORTALITY WARNING: HEPATOTOXICITY, INCLUDING HEPATIC VENO-OCCLUSIVE DISEASE (VOD) (ALSO KNOWN AS SINUSOIDAL OBSTRUCTION SYNDROME) and INCREASED RISK OF POST- HEMATOPOIETIC STEM CELL TRANSPLANT (HSCT) NON-RELAPSE MORTALITY See full prescribing information for complete boxed warning. • Hepatotoxicity, including fatal and life-threatening VOD occurred in patients who received BESPONSA. ( 5.1 ) • A higher post-HSCT non-relapse mortality rate occurred in patients receiving BESPONSA ( 5.2 ) HEPATOTOXICITY, INCLUDING VOD • Hepatotoxicity, including fatal and life-threatening VOD occurred in patients with relapsed or refractory acute lymphoblastic leukemia (ALL) who received BESPONSA. The risk of VOD was greater in patients who underwent HSCT after BESPONSA treatment; use of HSCT conditioning regimens containing 2 alkylating agents and last total bilirubin level ≥ upper limit of normal (ULN) before HSCT were significantly associated with an increased risk of VOD. • Other risk factors for VOD in patients treated with BESPONSA included ongoing or prior liver disease, prior HSCT, increased age, later salvage lines, and a greater number of BESPONSA treatment cycles. • Elevation of liver tests may require dosing interruption, dose reduction, or permanent discontinuation of BESPONSA. Permanently discontinue treatment if VOD occurs. If severe VOD occurs, treat according to standard medical practice [see Dosage and Administration (2.3) and Warnings and Precautions (5.1) ]. INCREASED RISK OF POST-HSCT NON-RELAPSE MORTALITY • There was higher post-HSCT non-relapse mortality rate in patients receiving BESPONSA, resulting in a higher Day 100 post-HSCT mortality rate [see Warnings and Precautions (5.2) ] .

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary Based on its mechanism of action and findings from animal studies [see Clinical Pharmacology (12.1) , Nonclinical Toxicology (13.1) ] , BESPONSA can cause embryo-fetal harm when administered to a pregnant woman . There are no available data on BESPONSA use in pregnant women to inform a drug-associated risk. In rat embryo-fetal development studies, inotuzumab ozogamicin caused embryo-fetal toxicity at maternal systemic exposures that were ≥ 0.4 times the exposure in patients at the maximum recommended dose, based on AUC [see Data ] . Advise patients of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies are 2–4% and 15–20%, respectively. Data Animal Data In embryo-fetal development studies in rats, pregnant animals received daily intravenous doses of inotuzumab ozogamicin up to 0.36 mg/m 2 during the period of organogenesis. Embryo-fetal toxicities including increased resorptions and fetal growth retardation as evidenced by decreased live fetal weights and delayed skeletal ossification were observed at ≥ 0.11 mg/m 2 (approximately 2 times the exposure in patients at the maximum recommended dose, based on AUC). Fetal growth retardation also occurred at 0.04 mg/m 2 (approximately 0.4 times the exposure in patients at the maximum recommended dose, based on AUC). In an embryo-fetal development study in rabbits, pregnant animals received daily intravenous doses up to 0.15 mg/m 2 (approximately 3 times the exposure in patients at the maximum recommended dose, based on AUC) during the period of organogenesis. At a dose of 0.15 mg/m 2 , slight maternal toxicity was observed in the absence of any effects on embryo‑fetal development.
