Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This phase I study will use Continual Reassessment Method (CRM) to establish a maximum tolerated dose (MTD) of DT2219ARL. Up to 3 dose levels will be tested with an additional dose level (-1) if dose level 1 proves too toxic. The goal of CRM is to identify the dose level which correspondences to a desired toxicity rate of 33% or less using grade 3 or 4 capillary leak syndrome and any grade 3 or greater toxicity attributed to DT2219ARL as the targeted toxicity (based on CTCAE version 4).
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Approximately 15 months after the last patient was enrolled under the original study plan, the protocol was redesigned by the Masonic Cancer Center at the University of Minnesota, building on the experience of the 1st 15 patients enrolled through the Texas centers. To increase efficiency, the study design was changed from the standard 3 x 3 dose escalation to a Continuous Reassessment Method (CRM) model testing 3 doses levels (40, 60, and 80 ug/kg) with an added feature of a dose level -1 (30 ug/kg) in the event dose level 1 proves too toxic. The maximum tolerated dose will be identified once 20 evaluable patients are enrolled.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Disease refractory to conventional therapy and other therapies of higher priority
* Age ≥ 12 years
* Karnofsky Performance status of ≥ 60% or, if less than 16 years of age, Lansky Play Score of ≥ 60 (appendix II)
* Patients must have recovered from effects of prior therapy - at least 2 weeks should have elapsed since the last dose of chemotherapy; however patients who have recovered from the effects of previous treatment and have a \>50% rise in peripheral blast count (confirmed twice) or \> 50% growth of lymph nodes are immediately eligible - Patients who have relapsed following autologous or allogeneic BMT are eligible
* In order to prevent tumor lysis syndrome, leukemia patients must have a peripheral blast count under 50 x 109/L. This should be achieved with hydroxyurea cytoreduction, prior to starting DT2219ARL as follows - patients with peripheral blasts and a WBC \>50 x 109/L, give hydroxyurea 1-5 g daily for up to 5 days to reduce WBC below 50 x 109/L
* Adequate organ function within 14 days (30 days for cardiac and pulmonary) of treatment start defined as:
* Creatinine: ≤ 1.5 x upper limit of institutional normal (ULN)
* Hepatic: SGOT (AST) or SGPT (ALT) \< 2.5 x ULN and total bilirubin \</= 1.5 x ULN
* General health: Serum albumin ≥ 3.0g/dL
* Pulmonary: PFTs \> 50% if symptomatic or prior known impairment
* Cardiac: LVEF by ECHO or MUGA ≥ 40%
* Agrees to stay within the Twin Cities metropolitan area (i.e. within 30 miles of the study center) for the duration of the treatment (at least 24 hours after the last dose) and 2) have a capable caregiver
* Women of childbearing potential and men should be advised and agree to practice effective methods of contraception during the course of study
* Voluntary written consent
Exclusion Criteria
* Presence of active CNS leukemia. CSF with \<5 WBC/uL will not exclude the patient
* Presence of any uncontrolled systemic infection
* Documented uncontrolled seizure disorder or abnormal neurological examination - a seizure disorder controlled with medication (i.e. no seizures in the previous 6 months) will not exclude a patient
* Documented penicillin or cephalosporin allergies
* Pregnant or lactating - Women of child bearing potential must have a negative pregnancy test within 14 days of study treatment start
