A Study of Subcutaneous Blinatumomab Administration in Participants With R/R and MRD+ B-ALL
A Phase 1/2 Open-label Study to Investigate the Safety, Efficacy, and Pharmacokinetics of Administration of Subcutaneous Blinatumomab for the Treatment of Adults and Adolescents With Relapsed or Refractory B Cell Precursor Acute Lymphoblastic Leukemia (R/R B-ALL) and Minimal Residual Disease Positive (MRD+) B-ALL

Brief Summary
The Phase I part of the study aims to evaluate the safety, efficacy, and tolerability of subcutaneous (SC) blinatumomab for treatment of Relapsed or Refractory B cell Precursor Acute Lymphoblastic Leukemia (R/R B-ALL), to determine the maximum tolerated dose (MTD), and recommended phase 2 dose(s) (RP2D) of SC administered blinatumomab. The Phase II part of the study will evaluate the safety, efficacy, and tolerability of SC blinatumomab for treatment of R/R B-ALL and Minimum Residual Disease Positive (MRD+) B-ALL in participants 12 years old and greater. It will also conduct a clinical pharmacokinetic (PK) evaluation of SC1 and SC2 blinatumomab formulations.

Study Arms (5)
Dose Escalation Phase: Blinatumomab Subcutaneous Formulation 1 (SC1)
EXPERIMENTALCohorts of at least 3 adult participants with R/R B-ALL will be treated with escalating doses of blinatumomab to determine the maximum tolerated dose (MTD). The MTD will be defined as the dose for which the estimate of the toxicity rate from an isotonic regression (Yan et al, 2017) is closest to the target toxicity rate. Safety, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy will be assessed.
Dose Expansion Phase: Blinatumomab SC1
EXPERIMENTALUp to 4 cohorts of adult participants with R/R B-ALL will be enrolled at different dose levels to support identification of the RP2D. Each cohort will aim to further assess safety, pharmacokinetics (PK), pharmacodynamics (PD), and efficacy.
Ph-IIC: Clinical PK Evaluation of SC Blinatumomab Formulations
EXPERIMENTAL1 cohort of adult participants will be enrolled into the Ph-IIC arm. The clinical PK evaluation cohort (Ph-IIC) will be conducted to compare the PK of SC1 and SC2 formulations at the preliminary RP2D determined from the dose expansion phase, in participants with R/R B-ALL.
Ph-IIR: Efficacy of SC Blinatumomab in Participants with R/R B-ALL
EXPERIMENTALThe efficacy of SC blinatumomab (in the SC2 formulation) will be evaluated in adults and adolescents with R/R B-ALL.
Ph-IIM: Efficacy of SC Blinatumomab in Participants with MRD+ B-ALL
EXPERIMENTALThe efficacy of SC blinatumomab (in the SC2 formulation) will be evaluated in adults and adolescents with MRD+ B-ALL.
Interventions
Blinatumomab will be administered as a subcutaneous (SC) injection.

- Time Frame
- Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.
- Access Criteria
- Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors. If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications. Further details are available at the URL below.
