Study Details

Study Description

Brief Summary

The trial proposed to evaluate the efficacy and safety of an inotuzumab ozogamicin followed by an age-adapted intermediate intensive consolidation therapy and maintenance treatment in patients with acute lymphoblastic leukemia older than 56 years

Condition or Disease Intervention/Treatment Phase
  • Drug: Inotuzumab ozogamicin
Phase 2

Detailed Description

Despite recent advances especially in younger patients, the prognosis of elderly patients with ALL remains dismal with a 5-year survival rate of around 20%, even after intensive chemotherapy.

Inotuzumab ozogamicin (PF-05208773; CMC-544) is an antibody-targeted intravenous (IV) chemotherapy agent composed of an anti-CD22 antibody linked to calicheamicin, a potent cytotoxic antitumor antibiotic.

After a prephase treatment, induction therapy will be based on inotuzumab ozogamicin and intrathecal therapy only. After a maximum of three cycles, patients will receive an age adapted intermediate dose consolidation chemotherapy based on the backbone of the German Multicenter Study Group for adult ALL (GMALL). This will be followed by a conventional maintenance therapy. All patients will be followed for cytological response, minimal residual disease and safety parameters.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Induction Therapy with Inotuzumab Ozogamicin

Patients will receive up to 3 cycles Inotuzumab with applications on day 1, 8 and 15 in each cycle. First dose will be 0.8 mg/m² on Day 1. All subsequent doses will be 0,5 mg/m².

Drug: Inotuzumab ozogamicin
Patients will receive standard of care chemotherapy (consolidation and maintenance) after Inotuzumab Ozogamicin.

Outcome Measures

Primary Outcome Measures

  1. Event free survival (EFS) at 12-months follow-up [At 12 months]

    An event is any of the following: persisting bone marrow blasts (more than 5% leukemic blasts) after two cycles of inotuzumab ozogamicin, relapse or death.

Secondary Outcome Measures

  1. Complete hematological remission [42 days]

    The rate of complete hematological remission after inotuzumab ozogamicin induction treatment

  2. MRD response after induction treatment [42 days]

    The rate of patients being negative for minimal residual disease (defined by RQ-PCR for at least one leukemia-specific IG/TR gene rearrangement or leukemia specific genetic aberration with a sensitivity of at least 10-4) after induction treatment

  3. Relapse free survival [two years]

    Relapse free survival after two years

  4. Molecular relapse [two years]

    The proportion of patients with molecular relapse

  5. Overall survival [two years]

    Overall survival after two years

  6. Death during induction [42 days]

    Death during induction

  7. Death in complete remission [up to 2 years]

    Death in complete remission

Eligibility Criteria

Criteria

Ages Eligible for Study:
56 Years to 74 Years
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  1. Male or female patients, ≥56 years of age and fit for therapy

  2. Newly diagnosed acute lymphoblastic leukemia (>25% marrow blasts, assessed by morphology; i.e. M3 marrow)

  3. Leukemic blasts must have CD22 surface expression of a least 20%, assessed by local/institutional flow cytometry of a bone marrow aspirate sample (assessment of CD22 via the reference lab for immungenetics is strongly recommended). In the case of an inadequate aspirate sample (dry tap), flow cytometry of peripheral blood specimen may be substituted if the patient has circulating blasts; alternatively, CD22 expression may be documented by immunohistochemistry of a bone marrow biopsy specimen

  4. No previous ALL-specific treatment with the exception of corticosteroids and/or single dose vincristine and/or a maximum of three doses of cyclophosphamide (cumulative dose of 600mg/m2) and the standard prephase treatment

  5. With or without documented CNS involvement

  6. Adequate liver function, including total serum bilirubin <2.0 x ULN unless the patient has documented Gilbert syndrome, and aspartate and alanine aminotransferase (AST and ALT) <2.5 x ULN If organ function abnormalities are considered due to leukemic infiltration of the liver, total serum bilirubin must be < 2.5 x ULN and AST/ALT <5 x ULN

  7. Serum creatinine <1.5 x upper limit of normal (ULN) or any serum creatinine level associated with a measured or calculated creatinine clearance of >40 mL/min

  8. WHO performance status ≤ 2

  9. Signed written inform consent

  10. Inclusion in GMALL registry

Exclusion Criteria:
  1. Philadelphia-chromosome or BCR-ABL positive ALL

  2. Burkitt's or mixed phenotype acute leukemia based on the WHO 2008 criteria

  3. Peripheral absolute lymphoblast count >10,000/μL after pre-phase treatment and before start of study medication

  4. Known systemic vasculitis (e.g. , Wegener's granulomatosis, polyarteritis nodosa, systemic lupus erythematosus), primary or secondary immunodeficiency (such as HIV infection or severe inflammatory disease)

  5. Current or chronic hepatitis B or C infection as evidenced by hepatitis B surface antigen and anti-hepatitis C antibody positivity, respectively, or known seropositivity or human immunodeficiency virus (HIV)

  6. Major surgery within <4 weeks before entry on study

  7. Unstable or severe uncontrolled medical condition (e.g., unstable cardiac function or unstable pulmonary condition)

  8. Concurrent active malignancy other than non-melanoma skin cancer, carcinoma in situ of the cervix, or localized prostate cancer that has been definitely treated with radiation or surgery; patients with previous malignancies are eligible provided that they have been disease free for >2 years

  9. Cardiac function, as measured by left ventricular ejection fraction (LVEF) that is less than 45%, or the presence of New York Heart Association (NYHA) stage III or IV congestive heart failure

  10. Myocardial infarction <6 months before randomization

  11. History of clinically significant ventricular arrhythmia, or unexplained syncope not believed to be vasovagal in nature, or chronic bradycardic states such as sinoatrial block or higher degrees of AV block unless a permanent pacemaker has been implanted

  12. Uncontrolled electrolyte disorders that can confound the effects of a QTc prolonging drug (e.g., hypokalemia, hypocalcemia, hypomagnesemia)

  13. History of chronic liver disease (e.g., cirrhosis) or suspected alcohol abuse

  14. History of hepatic veno-occlusive disease (VOD) or sinusoidal obstruction syndrome (SOS)

  15. Administration of live vaccine <6 weeks before randomization

  16. Evidence of uncontrolled current serious active infection (including sepsis, bacteremia, fungemia) or patients with a recent history (within 4 months) of deep tissue infections such as fasciitis or osteomyelitis

  18. Pregnant females; breastfeeding females; males and females of childbearing potential (a woman is considered of childbearing potential (WOCBP) i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile e.g. after hysterectomy or bilateral ovariectomy. Please refer to chapter 12.4 Contraceptive Requirements.) not using highly effective contraception or not agreeing to continue highly effective contraception for women at least 8 months an for men at least 5 months after the last dose of investigational product

  19. Participation in other studies involving investigational drug(s) (Phase I-IV) within 4 weeks before study inclusion

  20. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
