About this study
Official title: 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
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
BlinatumomabDrug
Also called AMG 103
Blinatumomab will be administered as a subcutaneous (SC) injection.
| Study group | Role | What they receive |
|---|---|---|
| Dose Escalation Phase: Blinatumomab Subcutaneous Formulation 1 (SC1) | Experimental | Cohorts 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. Receives: Drug: Blinatumomab |
| Dose Expansion Phase: Blinatumomab SC1 | Experimental | Up 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. Receives: Drug: Blinatumomab |
| Ph-IIC: Clinical PK Evaluation of SC Blinatumomab Formulations | Experimental | 1 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. Receives: Drug: Blinatumomab |
| Ph-IIR: Efficacy of SC Blinatumomab in Participants with R/R B-ALL | Experimental | The efficacy of SC blinatumomab (in the SC2 formulation) will be evaluated in adults and adolescents with R/R B-ALL. Receives: Drug: Blinatumomab |
| Ph-IIM: Efficacy of SC Blinatumomab in Participants with MRD+ B-ALL | Experimental | The efficacy of SC blinatumomab (in the SC2 formulation) will be evaluated in adults and adolescents with MRD+ B-ALL. Receives: Drug: Blinatumomab |

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.

| Arm | Type | Receives |
|---|---|---|
| Dose Escalation Phase: Blinatumomab Subcutaneous Formulation 1 (SC1) | Experimental | Drug: BlinatumomabCohorts 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 | Experimental | Drug: BlinatumomabUp 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 | Experimental | Drug: Blinatumomab1 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 | Experimental | Drug: BlinatumomabThe 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 | Experimental | Drug: BlinatumomabThe efficacy of SC blinatumomab (in the SC2 formulation) will be evaluated in adults and adolescents with MRD+ B-ALL. |

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Blinatumomab in people with B Cell Precursor Acute Lymphoblastic Leukemia, run by Amgen at 109 sites in 20 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 18 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 28 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 109 sites in China, United States, Spain, Australia, France and 15 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose Escalation Phase: Number of participants who experience dose limiting toxicities (DLTs) (time frame: Up to 29 days). The study lists 11 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04521231, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2026.
