Black Box 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 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. 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.

Pharmacology

Mechanism of Action

• Inotuzumab ozogamicin is a CD22-directed antibody-drug conjugate (ADC). Inotuzumab recognizes human CD22. The small molecule, N-acetyl-gamma-calicheamicin, is a cytotoxic agent that is covalently attached to the antibody via a linker. Nonclinical data suggest that the anticancer activity of inotuzumab ozogamicin is due to the binding of the ADC to CD22-expressing tumor cells, followed by internalization of the ADC-CD22 complex, and the intracellular release of N-acetyl-gamma-calicheamicin dimethylhydrazide via hydrolytic cleavage of the linker. Activation of N-acetyl-gamma-calicheamicin dimethylhydrazide induces double-strand DNA breaks, subsequently inducing cell cycle arrest and apoptotic cell death.

Structure

Pharmacodynamics

• During the treatment period, the pharmacodynamic response to BESPONSA was characterized by the depletion of CD22-positive leukemic blasts.

Cardiac Electrophysiology

• In a randomized clinical study in patients with relapsed or refractory ALL, increases in QTcF of ≥ 60 msec from baseline were measured in 4/162 patients (3%) in the BESPONSA arm and 3/124 patients (2%) in the Investigator's choice of chemotherapy arm. Increases in QTcF of > 500 msec were observed in none of the patients in the BESPONSA arm and 1/124 patients (1%) in the Investigator's choice of chemotherapy arm. Central tendency analysis of the QTcF interval changes from baseline showed that the highest mean (upper bound of the 2-sided 90% CI) for QTcF was 15.3 (21.1) msec, which was observed at Cycle 4/Day 1/1 hour in the BESPONSA arm.

Pharmacokinetics

• The mean Cmax of inotuzumab ozogamicin was 308 ng/mL. The mean simulated total AUC per cycle was 100,000 ng∙h/mL. In patients with relapsed or refractory ALL, steady-state drug concentration was achieved by Cycle 4. Following administration of multiple doses, a 5.3 times accumulation of inotuzumab ozogamicin was predicted by Cycle 4.

Distribution

• N-acetyl-gamma-calicheamicin dimethylhydrazide is approximately 97% bound to human plasma proteins in vitro. In humans, the total volume of distribution of inotuzumab ozogamicin was approximately 12 L.

Elimination

• The pharmacokinetics of inotuzumab ozogamicin was well characterized by a 2-compartment model with linear and time-dependent clearance components. In 234 patients with relapsed or refractory ALL, the clearance of inotuzumab ozogamicin at steady state was 0.0333 L/h and the terminal half-life (t½) was 12.3 days. Following administration of multiple doses, a 5.3 times accumulation of inotuzumab ozogamicin was predicted by Cycle 4.

Metabolism

• In vitro, N-acetyl-gamma-calicheamicin dimethylhydrazide was primarily metabolized via nonenzymatic reduction. In humans, N-acetyl-gamma-calicheamicin dimethylhydrazide serum levels were typically below the limit of quantitation.

Specific Populations

• The effect of intrinsic factors on inotuzumab ozogamicin pharmacokinetics was assessed using a population pharmacokinetic analysis unless otherwise specified. Age (18 to 92 years of age), sex, and race (Asian versus non-Asian [Caucasian, Black, and Unspecified]) had no clinically significant effect on the pharmacokinetics of inotuzumab ozogamicin. Body surface area was found to significantly affect inotuzumab ozogamicin disposition. BESPONSA is dosed based on body surface area.

Patients with Renal Impairment

• The clearance of inotuzumab ozogamicin in patients with mild renal impairment (creatinine clearance [CLcr; based on the Cockcroft-Gault formula] 60–89 mL/min; n=237), moderate renal impairment (CLcr 30–59 mL/min; n=122), or severe renal impairment (CLcr 15–29 mL/min; n=4) was similar to patients with normal renal function (CLcr ≥90 mL/min; n=402). The safety and efficacy of inotuzumab ozogamicin in patients with end stage renal disease with or without hemodialysis is unknown.

Patients with Hepatic Impairment

• The clearance of inotuzumab ozogamicin in patients with mild hepatic impairment (total bilirubin ≤ULN and AST > ULN, or total bilirubin >1.0–1.5 × ULN and AST any level; n=150) was similar to patients with normal hepatic function (total bilirubin/AST ≤ULN; n=611). There is insufficient data in patients with moderate and severe hepatic impairment (total bilirubin >1.5 ULN).

Drug Interactions

• In vitro

• Effect of Metabolic Pathways and Transporter Systems on BESPONSA

• N-acetyl-gamma-calicheamicin dimethylhydrazide is a substrate of P-glycoprotein (P-gp).

• At clinically relevant concentrations, N-acetyl-gamma-calicheamicin dimethylhydrazide had a low potential to:

• Inhibit cytochrome P450 (CYP 450) Enzymes: CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4/5.

• Induce CYP450 Enzymes: CYP1A2, CYP2B6, and CYP3A4.

• Inhibit UGT Enzymes: UGT1A1, UGT1A4, UGT1A6, UGT1A9, and UGT2B7.

• Inhibit Drug Transporters: P-gp, breast cancer resistance protein (BCRP), organic anion transporter (OAT)1 and OAT3, organic cation transporter (OCT)2, and organic anion transporting polypeptide (OATP)1B1 and OATP1B3.

• At clinically relevant concentrations, inotuzumab ozogamicin had a low potential to:

• Inhibit CYP450 Enzymes: CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4/5.

• Induce CYP450 Enzymes: CYP1A2, CYP2B6, and CYP3A4.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

• Formal carcinogenicity studies have not been conducted with inotuzumab ozogamicin. In toxicity studies, rats were dosed weekly for 4 or 26 weeks with inotuzumab ozogamicin at doses up to 4.1 mg/m2 and 0.73 mg/m2, respectively. After 26 weeks of dosing, rats developed hepatocellular adenomas in the liver at 0.73 mg/m2 (approximately 2 times the exposure in patients at the maximum recommended dose, based on AUC).

• Inotuzumab ozogamicin was clastogenic in vivo in the bone marrow of male mice that received single doses ≥1.1 mg/m2. This is consistent with the known induction of DNA breaks by calicheamicin. N-acetyl-gamma-calicheamicin dimethylhydrazide (the cytotoxic agent released from inotuzumab ozogamicin) was mutagenic in an in vitro bacterial reverse mutation (Ames) assay.

• In a female fertility and early embryonic development study, female rats were administered daily intravenous doses of inotuzumab ozogamicin up to 0.11 mg/m2 for 2 weeks before mating through Day 7 of pregnancy. An increase in the proportion of resorptions and decrease in the number of viable embryos and gravid uterine weights were observed at the 0.11 mg/m2 dose level (approximately 2 times the exposure in patients at the maximum recommended dose, based on AUC). Additional findings in female reproductive organs occurred in repeat-dose toxicology studies and included decreased ovarian and uterine weights, and ovarian and uterine atrophy. Findings in male reproductive organs occurred in repeat-dose toxicology studies and included decreased testicular weights, testicular degeneration, hypospermia, and prostatic and seminal vesicle atrophy. Testicular degeneration and hypospermia were nonreversible following a 4-week nondosing period. In the chronic studies of 26-weeks duration, adverse effects on reproductive organs occurred at ≥0.07 mg/m2 in male rats and at 0.73 mg/m2 in female monkeys.

Clinical Studies

Patients With Relapsed or Refractory ALL – INO-VATE ALL

• The safety and efficacy of BESPONSA were evaluated in INO-VATE ALL (NCT01564784) a randomized (1:1), open-label, international, multicenter study in patients with relapsed or refractory ALL. Patients were stratified at randomization based on duration of first remission (< 12 months or ≥ 12 months, salvage treatment (Salvage 1 or 2) and patient age at randomization (< 55 or ≥ 55 years). Eligible patients were ≥ 18 years of age with Philadelphia chromosome-negative or Philadelphia chromosome-positive relapsed or refractory B-cell precursor ALL. All patients were required to have ≥ 5% bone marrow blasts and to have received 1 or 2 previous induction chemotherapy regimens for ALL. Patients with Philadelphia chromosome-positive B-cell precursor ALL were required to have disease that failed treatment with at least 1 tyrosine kinase inhibitor and standard chemotherapy. Table 1 shows the dosing regimen used to treat patients.

• Among all 326 patients who were randomized to receive BESPONSA (N=164) or Investigator's choice of chemotherapy (N=162), 215 patients (66%) had received 1 prior treatment regimen for ALL and 108 patients (33%) had received 2 prior treatment regimens for ALL. The median age was 47 years (range: 18–79 years), 276 patients (85%) had Philadelphia chromosome-negative ALL, 206 patients (63%) had a duration of first remission < 12 months, and 55 patients (17%) had undergone a HSCT prior to receiving BESPONSA or Investigator's choice of chemotherapy. The two treatment groups were generally balanced with respect to the baseline demographics and disease characteristics.

• All evaluable patients had B-cell precursor ALL that expressed CD22, with ≥ 90% of evaluable patients exhibiting ≥ 70% leukemic blast CD22 positivity prior to treatment, as assessed by flow cytometry performed at a central laboratory.

• The efficacy of BESPONSA was established on the basis of CR, the duration of CR, and proportion of MRD-negative CR (< 1 × 10-4 of bone marrow nucleated cells by flow cytometry) in the first 218 patients randomized. CR, duration of remission (DoR), and MRD results in the initial 218 randomized patients were consistent with those seen in all 326 randomized patients.

• Among the initial 218 randomized patients, 64/88 (73%) and 21/88 (24%) of responding patients per EAC achieved CR/CRi in Cycles 1 and 2, respectively, in the BESPONSA arm, and 29/32 (91%) and 1/32 (3%) of responding patients per EAC achieved a CR/CRi in Cycles 1 and 2, respectively, in the Investigator's choice of chemotherapy arm.

• Table 8 shows the efficacy results from this study.

This image is provided by the National Library of Medicine.

• Among the initial 218 patients, as per EAC assessment, 32/109 patients (29%) in the BESPONSA arm achieved complete remission with partial hematologic recovery (CRh; defined as <5% blasts in the bone marrow, ANC > 0.5 × 109/L, and platelet counts > 50 × 109/L but not meeting full recovery of peripheral blood counts) versus 6/109 patients (6%) in the Investigator's choice of chemotherapy arm, and 71/109 patients (65%) in the BESPONSA arm achieved CR/CRh versus 25/109 patients (23%) in the Investigator's choice of chemotherapy arm.

• Overall, 79/164 patients (48%) in the BESPONSA arm and 35/162 patients (22%) in the Investigator's choice of chemotherapy arm had a follow-up HSCT.

• Figure 1 shows the analysis of overall survival (OS). The analysis of OS did not meet the pre-specified boundary for statistical significance.
