ABT-751 With Chemotherapy for Relapsed Pediatric ALL

Stopped early · Phase 1/Phase 2

Conditions studied: Recurrent Pediatric ALL, Relapsed Pediatric ALL, Acute Lymphoblastic Leukemia, Refractory Pediatric ALL

In brief

This is a phase I/II study of an investigational drug called ABT-751, produced by Abbott Laboratories, given in combination with chemotherapy drugs used to treat acute lymphoblastic leukemia (ALL) that has come back (recurred). The phase I portion of this study is being done to find the highest dose of ABT-751 that can be given safely in combination with other chemotherapy drugs. A safe dose is one that does not result in unacceptable side effects. After a safe dose for ABT-751 given with chemotherapy has been found, the study will add additional patients to find out if ABT-751 (given at the maximal safe dose) when given with additional chemotherapy is an effective therapy for the treatment of children with relapsed ALL. It is expected that approximately 15-35 children and young adults will take part in this study.

Who can join

Age: any, up to 21. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age Patients must be < 21 years of age when enrolled onto this study. T2005-001 Protocol version 6/27/2007 17
• Diagnosis
• Patients must have relapsed or refractory ALL with a M3 marrow (marrow blasts >25%) without clinical evidence of testicular disease or laboratory evidence of CNS disease defined as CSF WBC > 5 cells/microliter and blasts. (See Appendix I for method of evaluating traumatic lumbar punctures.) Patients in early first relapse (defined as a patient who relapses less than 36 months from their initial remission [CR1]) are eligible for the phase I portion of the trial.
• Performance Level Karnofsky > 60% for patients > 10 years of age and Lansky > 60% for patients < 10 years of age.
• Prior Therapy Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.
• Prior anthracycline exposure: Patients must have less than 300mg/m2 lifetime exposure of anthracycline chemotherapy. (See Appendix III for calculation criteria)
• Stem Cell Transplant (SCT): Patients are eligible 6 months after allogeneic stem cell transplant as long as patients are not actively being treated for graft-versus-host-disease (GvHD).
• During the phase I portion of the trial, there is no limit on the number of prior treatment regimens.
• During the phase II portion of the trial, patients must have had two or more prior therapeutic attempts defined as:
• Persistent initial disease after two induction attempts, or
• Relapse after one-reinduction attempt (2nd relapse), or
• Persistent disease after first relapse and initial re-induction attempt (Patients in any first relapse are not eligible for the phase II portion of the study)
• During the phase II portion of the trial, patients must have no more than 3 prior therapeutic attempts and it must be at least 6 months since the last treatment with a "VPLD" induction/re-induction regimen.
• Reproductive Function
• Female patients of childbearing potential must have a negative urine or serum pregnancy test confirmed prior to enrollment and within 48 hours of starting therapy.
• Female patients with infants must agree not to breastfeed their infants while on this study.
• Male and female patients of child-bearing potential must agree to use an effective method of contraception approved by the investigator during the study and for 3 months following completion of therapy.

You may not qualify if…

• Drug Allergies
• Patients will be excluded if they have allergies to the following drugs:
• Asparaginase products
• Sulfa containing medications
• Renal Function Patients will be excluded if their serum creatinine is > the upper limit of normal (ULN) for age at the institution's laboratory.
• Liver/Pancreatic Function
• 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.
• SGPT (ALT) > 4 x institutional ULN
• Grade 3 or greater pancreatitis as defined by the CTCAE v3.0
• Amylase or Lipase > 2 x institutional ULN
• Cardiac Function Patients will be excluded if their shortening fraction by echocardiogram is less than 30%.
• Infection Patients will be excluded if they have an active, uncontrolled infection.
• Patients with grade 2 or greater motor or sensory neuropathy per CTC 3.0 criteria.
• Patients with grade 2 or greater Ileus (neuroconstipation) per CTC 3.0 criteria.
• Patients currently being treated with coumadin.
• Patients currently being treated with colchicines.
• 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.)
• Patients planning on receiving other anti-cancer therapies while on this study.
• Patients who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study.
• Patients who, based on BSA and current dose level, require a daily dose of ABT-751 that is less than 25mg per day.
• Patients who have started protocol therapy prior to enrollment. Patient may still enroll if IT Ara-C or IT MTX were given within 48 hours of study enrollment as part of the diagnostic lumbar procedure. These patients will not participate in the CSF PK portion of the study.
