  • 0.9mg/vial

Acute Lymphoblastic Leukemia

Indicated for relapsed/refractory B-cell precursor acute lymphoblastic leukemia

See Dosing Considerations

Cycle 1 for all patients

  • Total dose of inotuzumab: 1.8 mg/m² per 21-day cycle, administered as 3 divided doses
  • Day 1: 0.8 mg/m²
  • Day 8 and 15: 0.5 mg/m²
  • Duration of cycle 1 is 21 days; may extend to 28 days (eg, 7-day treatment-free interval starting on day 21) if patient achieves a complete remission (CR) or complete remission with incomplete hematologic recovery (CRi), and/or to allow recovery from toxicity
  • CR is defined as < 5% blasts in bone marrow and absence of peripheral blood leukemic blasts, full recovery of peripheral blood counts (platelets ≥ 100 × 10^9/L and absolute neutrophil counts [ANC] ≥ 1 × 10^9/L) and resolution of any extramedullary disease
  • CRi is defined as < 5% blasts in bone marrow and absence of peripheral blood leukemic blasts, incomplete recovery of peripheral blood counts (platelets < 100 × 10^9/L and/or ANC < 1 × 10^9/L) and resolution of any extramedullary disease

Patients who achieve a CR or CRi

  • Total dose of inotuzumab is 1.5 mg/m² per 28-day cycle, including a 7-day treatment-free interval starting on day 21, administered as 3 divided doses
  • Day 1, 8, and 15: 0.5 mg/m² IV

Patients who do not achieve a CR or CRi

  • Total dose of inotuzumab is 1.8 mg/m² per 28-day cycle, including a 7-day treatment-free interval starting on day 21 administered as 3 divided doses
  • Day 1: 0.8 mg/m² IV
  • Day 8 and 15: 0.5 mg/m² IV
  • Patients who do not achieve a CR or CRi ≤3 cycles should discontinue treatment

Dosage Modifications

Renal impairment

  • Mild to moderate (CrCl 30-89 mL/min): No dosage adjustment necessary
  • End-stage renal disease (CrCl <30 mL/min) and/or hemodialysis: Safety and efficacy is not established

Hepatic impairment

  • Total bilirubin (≤1.5x ULN) and AST/ALT (≤2.5x ULN): No dosage adjustment necessary
  • Total bilirubin >1.5x ULN and/or AST/ALT >2.5x ULN: Limited safety information; caution with use

Doses within a treatment cycle (eg, Days 8 and/or 15) do not need to be interrupted due to neutropenia or thrombocytopenia but interruptions within a cycle are recommended for non-hematologic toxicities; if dose is reduced due to drug related toxicity, it must not be re-escalated

Hematologic toxicities

  • Baseline absolute neutrophil count (ANC) ≥1 × 10^9/L: If ANC decreases, then interrupt next cycle until ANC ≥1 × 10^9/L; discontinue inotuzumab if low ANC persists for >28 days and is considered an inotuzumab-related toxicity
  • Baseline platelet count >50 × 10^9; /L: If platelet count decreases, then interrupt next cycle if platelet count was ≥50 × 10^9 /L; discontinue inotuzumab if low platelet count persists >28 days and is considered an inotuzumab-related toxicity
  • Baseline ANC>1 × 10^9 /L and/or platelet count <50 × 10^9 /L
    • If ANC or platelet count decreases, then interrupt next cycle of treatment until at least one of following occurs:
    • ANC and platelet count recover to at least baseline levels for prior cycle
    • ANC recovers ≥1 × 10^9 /L and platelet count ≥50 × 10^9 /L
    • Stable/improved disease (based on most recent bone marrow assessment) and ANC and platelet count decrease is correlated to the underlying disease (not considered to be inotuzumab-related toxicity)

Nonhematologic toxicities

  • Venoocclusive disease (VOD) or other severe liver disease: Permanently discontinue
  • Nonhematologic toxicity grade 2 or higher: Interrupt treatment until recovery to
  • Total bilirubin >1.5x ULN and AST/ALT >2.5x ULN
    • Interrupt dosing until recovery of total bilirubin ≤1.5x ULN and AST/ALT ≤2.5x ULN prior to each dose unless due to Gilbert syndrome or hemolysis
    • Permanently discontinue treatment if total bilirubin does not recover ≤1.5x ULN or AST/ALT ≤2.5x ULN
  • Infusion-related reactions
    • Interrupt infusion and institute appropriate medical management; depending on severity of infusion-related reaction, consider discontinuation of infusion or administration of steroids and antihistamines
    • Severe or life-threatening infusion reactions: Permanently discontinue treatment
  • Dose modifications depending on dosing interruption
    • <7 days (within a cycle): Interrupt next dose (maintain a minimum of 6 days between doses)
    • ≥7 days: Omit next dose within current cycle
    • ≥14 days: Once adequate recovery is achieved, decrease total dose by 25% for subsequent cycle; if further dose modifications are required, decrease number of doses to 2 per cycle for subsequent cycles; if dosing modifications are not tolerated, then permanently discontinue treatment

Dosing Considerations

Premedication with a corticosteroid, antipyretic, and antihistamine is recommended prior to dosing

Observe patient during and for at least 1 hr post infusion for infusion-related signs/symptoms

Prior to initial dose, in patients with circulating lymphoblasts, cytoreduction with a combination of hydroxyurea, steroids, and/or vincristine is recommended to achieve a peripheral blast count ≤10,000/mm³

Patients proceeding to hematopoietic stem cell transplantation (HSCT): Duration of inotuzumab treatment is 2 cycles; patients who do not achieve CR or CRi and minimal residual disease (MRD) negativity after 2 cycles may consider a third cycle

Patients not proceeding to HSCT: Additional cycles may be administered; not to exceed 6 cycles

                • Risk of myelosuppression; complications, including infections and bleeding/hemorrhagic events, observed; monitor complete blood cell counts prior to initiating; monitor for signs/symptoms of infection, bleeding/hemorrhage, or other effects of myelosuppression during treatment; if necessary, administer prophylactic anti-infectives and use surveillance testing during and after treatment
                • Management of severe infection, bleeding/hemorrhage, or other effects of myelosuppression, including severe neutropenia or thrombocytopenia, may require dosing interruption, dose reduction, or permanent discontinuation

                Infusion-related reactions

                • Infusion-related reactions may occur; premedicate with a corticosteroid, antipyretic, and antihistamine prior to dosing
                • Monitor closely during and for at least 1 hr after the end of infusion for potential onset of infusion-related reactions (eg, fever, chills, rash, or breathing problems); interrupt infusion and institute appropriate medical management if an infusion-related reaction occurs
                • See Dosage Modifications

                Pregnancy

                Pregnancy

                Based on its mechanism of action and findings from animal studies, inotuzumab can cause embryofetal harm when administered to a pregnant woman; no available data for use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage

                If used during pregnancy, or if patient becomes pregnant while taking inotuzumab, advise patient of the potential risk to a fetus

                Animal data

                • In rat embryofetal development studies, inotuzumab ozogamicin caused embryofetal toxicity at maternal systemic exposures that were ≥0.4 times exposure in patients at maximum recommended dose, based on AUC; pregnant rats received daily IV doses of inotuzumab ozogamicin up to 0.36 mg/m² during organogenesis; embryofetal toxicities, including increased resorptions and fetal growth restriction, as evidenced by decreased live fetal weights and delayed skeletal ossification, were observed at ≥0.11 mg/m² (~2 times the exposure in patients at maximum recommended dose, based on AUC); fetal growth restriction also occurred at 0.04 mg/m² (~0.4 times the exposure in patients at the maximum recommended dose, based on AUC)

                Females and Males of Reproductive Potential

                • Based on findings in animals, inotuzumab may impair fertility in males and females of reproductive potential
                • Pregnancy testing
                  • Verify the pregnancy status of females of reproductive potential prior to initiating inotuzumab
                • Contraception
                  • Advise females of reproductive potential to avoid becoming pregnant while receiving inotuzumab
                  • Advise females of reproductive potential to use effective contraception during treatment with inotuzumab and for at least 8 months after the last dose
                  • Advise males with female partners of reproductive potential to use effective contraception during treatment with inotuzumab and for at least 5 months after the last dose

                Lactation

                Unknown if distributed in human breast milk

                No data on presence of inotuzumab ozogamicin or its metabolites in human milk, its effects on breastfed infant, or effects on milk production

                Because of potential for adverse reactions in breastfed infants, advise women not to breastfeed during treatment with inotuzumab and for at least 2 months after the last dose

                Pregnancy Categories

                A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                NA: Information not available.

                Pharmacology

                Mechanism of Action

                CD22-directed antibody-drug conjugate (ADC) recognizes human CD22; small molecule, N-acetyl-gamma-calicheamicin, is a cytotoxic agent that covalently attaches to antibody via a linker

                Nonclinical data suggest anticancer activity of inotuzumab ozogamicin is due to binding of ADC to CD22-expressing tumor cells, followed by internalization of ADC-CD22 complex, and ultimately activating N-acetyl-gamma-calicheamicin 19 dimethylhydrazide, which induces double-strand DNA breaks, subsequently inducing cell cycle arrest and apoptotic cell death

                Absorption

                Peak plasma concentration: 308 ng/mL

                AUC: 100,000 ng·h/mL

                Steady-state drug concentration was achieved by cycle 4

                Distribution

                Protein bound: 97%

                Vd: ~12 L

                Metabolism

                N-acetyl-gamma-calicheamicin dimethylhydrazide was primarily metabolized via nonenzymatic reduction

                Elimination

                Clearance, steady state: 0.0333 L/h

                Half-life: 12.3 days
