Overview
Brief Summary
The purpose of this study is to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D), safety and toxicity, and pharmacokinetics (PK) of ixazomib administered intravenously in combination with multiagent reinduction chemotherapy in pediatric participants with relapsed/refractory ALL or LLy.
Detailed Description
29-Apr-2020 Enrollment of new patients into this study has been paused due to the COVID-19 situation. The duration of this pause is dependent on the leveling and control of the COVID-19 pandemic. The drug being tested in this study is called Ixazomib. Ixazomib is being tested to determine the MTD or RP2D of intravenous ixazomib when administered in combination with multiagent chemotherapy (reinduction therapy) in pediatric participants with relapsed or refractory ALL or relapsed/refractory LLy. The study will enroll approximately 18 participants. Doses of ixazomib will be escalated according to a standard 3+3 dose escalation schema. Participants aged \>= 1 year will receive the starting dose of 1.0 mg/m\^2 and participants aged \<1 year will receive the starting dose of 0.03 mg/kg. Ixazomib will be administered in combination with multiagent reinduction therapy. The dose escalation phase will determine the MTD and/or RP2D of ixazomib. Dose escalation will be based on the observed safety and tolerability data. Participants aged \<1 year will be assessed separately and will not contribute to the dose escalation assessment. This multi-center trial will be conducted in the United States and Spain. The overall time to participate in this study is approximately 30 months. Participants will be followed up to Day 60 after the first dose of study drug for a follow-up assessment.

Eligibility Criteria
Inclusion Criteria
- •Diagnosis of relapsed/refractory ALL with or without extramedullary disease, including central nervous system (CNS)2 (\<5 white blood cell \[WBC\]/mcL\] in the cerebrospinal fluid \[CSF\] with blasts) and CNS3 (\>=5 WBC/mcL in the CSF with blasts), or relapsed/refractory LLy. Participants with mixed-phenotype ALL or mature (Burkitt-like) leukemia are excluded.
- •Relapsed/refractory ALL must have \>=5% blasts in the bone marrow by morphology.
- •Relapsed/refractory LLy participants must have measurable disease documented by clinical, radiologic, and histologic criteria.
- •A Karnofsky performance status of \>=50% (for participants aged \>16 years) and a Lansky performance status of \>=50% (for participants aged \<=16 years).
- •Adequate organ function.
- •Failure of 1 or more therapeutic attempts.
- •Full recovery from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy before entering this study, as follows:
- •Cytoreduction with hydroxyurea: Hydroxyurea can be initiated and continued for up to 24 hours before the start of protocol therapy.
- •Cytotoxic therapy: At least 14 days must have elapsed since the completion of the last dose of chemotherapy, except intrathecal (IT) chemotherapy and/or maintenance therapy, such as vincristine (VCR), mercaptopurine, methotrexate, or glucocorticoids. There is no waiting period for those relapsing on maintenance therapy.
- •Hematopoietic stem cell transplantation (HSCT): Participants who have relapsed after HSCT are eligible, provided they have no evidence of acute or chronic graft-versus-host disease (GVHD), are not receiving GVHD prophylaxis or treatment, and are at least 90 days posttransplant at the time of enrollment.
Exclusion Criteria
- Not provided
Arms & Interventions
Ixazomib
Ixazomib, injection, intravenously, once on Days 1, 4, 8, and 11 in a single 29-day treatment cycle in combination with multiagent reinduction therapy. Participants \>= 1 year will receive the starting dose of 1.0 milligram per square meter (mg/m\^2) and \<1 year will receive the starting dose of 0.03 milligram per kilogram (mg/kg). The dose escalation phase will determine the MTD or RP2D of Ixazomib. Dose of Ixazomib will be escalated based on the observed safety and tolerability data.
Intervention: Ixazomib
Outcomes
Primary Outcomes
Number of Participants with Dose-limiting Toxicities (DLT) During Reinduction Chemotherapy
Time Frame: Up to Day 29
DLT: Grade 4 nonhematologic toxicity after first dose of ixazomib and is probably/definitely attributable to the ixazomib treatment regimen, with exceptions, example fever/infection with/without hospitalization, fatigue and gastrointestinal symptoms, hypofibrinogenemia, metabolic/laboratory abnormalities that resolve to less than or equal to(\<=)Grade 2 within 7 days. Any Grade 3/4 nonhematologic toxicity after first dose of ixazomib that is possibly/probably/definitely attributable to the ixazomib treatment regimen and results in omission of subsequent dose of chemotherapy, with exception of fever/infection. Hematologic toxicities: Failure to recover a peripheral absolute neutrophil count (ANC) ≥0.5\*10\^9 per liter (/L) and a platelet count ≥50\*10\^9/L due to documented bone marrow hypoplasia (cellularity \<10 20%) within 42 days after the beginning of systemic chemotherapy without evidence of active disease by bone marrow evaluation or active infection.
Cmax: Maximum Observed Plasma Concentration for Ixazomib
Time Frame: Day 1 pre-dose and at multiple time points (up to 72 hours) post-dose and Day 11 pre-dose and at multiple time points (up to 264 hours) post-dose
AUCt: Area Under the Plasma Concentration-time Curve From Time 0 to Time t for Ixazomib
Time Frame: Day 1 pre-dose and at multiple time points (up to 72 hours) post-dose and Day 11 pre-dose and at multiple time points (up to 264 hours) post-dose
