Erwinase for Patients With Relapsed/Refractory Acute Lymphoblastic Leukemia (ALL) (IND 104224)

• Status: Terminated
• Trial end date: 2010-06-04
• Target enrollment: 0
• Participant gender: All

Summary

This is a phase I study using the Erwinia form of asparaginase in place of the E. coli form using a standard re-induction regimen (Vincristine, Dexamethasone, Doxorubicin) for patients with relapsed ALL who have developed an allergy to the E. coli formulation. This study will administer the drug intravenously instead of the usual intramuscular route. The dose of Erwinia will be escalated in the absence of dose limiting toxicity. Patients must have first or second relapse ALL with a history of prior systemic reaction to E. coli asparaginase.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Therapeutic Advances in Childhood Leukemia Consortium
• Treatments: Asparaginase; BB 1101; Cytarabine; Dexamethasone; Dexamethasone 21-phosphate; Dexamethasone acetate; Dexrazoxane; Doxorubicin; Methotrexate; Razoxane; Vincristine

Criteria

Inclusion Criteria The eligibility criteria listed below are interpreted literally and cannot be waived.

1. Age Patients must be >1 and < 21 years of age when enrolled onto this study.

2. Diagnosis Patients must have relapsed or refractory ALL with a M3 marrow (marrow blasts >25%) who have had no more than two prior therapeutic attempts. Patients with CNS 1, 2, or 3 or testicular disease are eligible. (See section 11.3 for CNS definitions)

3. E. coli Asparaginase Allergy Patients must have a history of prior systemic allergic reaction to E. coli asparaginase (native or pegylated), such as urticaria, wheezing, or anaphylaxis. Local reactions are not sufficient.

4. Performance Level Karnofsky > 50% for patients > 10 years of age and Lansky > 50% for patients < 10 years of age.

5. Prior Therapy Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.

1. Patients may be in first or second relapse and should not have received more than 2 induction attempts (including frontline therapy).

2. Prior anthracycline exposure: Patients must have less than 400mg/m2 lifetime exposure of anthracycline chemotherapy.

3. Stem Cell Transplant (SCT): Patients are eligible after allogeneic stem cell transplant as long as patients are not actively being treated for graft-versus-host-disease (GvHD).

4. Patients may have received previous therapy using intramuscular (IM) Erwinase. Patients who have received Erwinase intravenously will be excluded.

6. Reproductive Function

1. Female patients of childbearing potential must have a negative urine or serum pregnancy test confirmed prior to enrollment.

2. Female patients with infants must agree not to breastfeed their infants while on this study.

3. Male and female patients of child-bearing potential must agree to use an effective method of contraception approved by the investigator during the study.

Exclusion Criteria

1. Prior Stroke Patients with a prior history of asparaginase associated stroke are excluded. Patients with a history of other asparaginase related deep-venous thromboses (including intra-cranial thromboses without evidence of stroke or hemorrhage) are eligible.

2. Down Syndrome Patients with Down Syndrome will be excluded.

3. Prior Pancreatitis Patients with prior history of Grade 2 or greater asparaginase-induced symptomatic pancreatitis will be excluded.

4. Renal Function Patients will be excluded if their serum creatinine is > 1.5 x the upper limit of normal for age at the institution's laboratory.

5. Liver/Pancreatic Function

Patients will be excluded if their lab results are as follows:

1. Direct bilirubin > 1.5x the institutional ULN for age. A total bilirubin result that is less than 1.5 times the institutional ULN for age may be used for eligibility if a direct bilirubin result is not available.

2. SGPT (ALT) > 4 x institutional ULN

3. Amylase or Lipase > 2 x institutional ULN

6. Cardiac Function Patients will be excluded if their shortening fraction by echocardiogram is less than the institutional normal for age or an ejection fraction by MUGA is less than the institutional normal for age.

7. Infection Patients will be excluded if they have an active uncontrolled infection.

8. Patients planning on receiving other investigational agents while on this study. (An investigational agent is defined as any drug not currently approved for use in humans.)

9. Patients planning on receiving other anti-cancer therapies while on this study.

10. Patients who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study.

11. Patients who have started protocol therapy prior to enrollment. Patient may still enroll if IT therapy was given within 72 hours of study enrollment as part of the diagnostic lumbar procedure.
