A Study Evaluating Subcutaneous Versus Intravenous Blinatumomab in Newly Diagnosed Adults With B-cell Precursor Acute Lymphoblastic Leukaemia

Официальное название

A Phase 3, Open-label, Randomized, Controlled Trial of Subcutaneous Versus Intravenous Blinatumomab in Newly Diagnosed Adults With Philadelphia Chromosome Negative B-cell Precursor Acute Lymphoblastic Leukaemia

Обзор

The main objective of this trial is to demonstrate that subcutaneous (SC) blinatumomab in conjunction with chemotherapy (Arm B) is non-inferior to continuous intravenous infusion (cIV) blinatumomab in conjunction with chemotherapy (Arm A) in overall survival (OS) in newly diagnosed participants with Philadelphia chromosome (Ph) negative B-cell precursor acute lymphoblastic leukemia (B-ALL) who are in complete remission (CR) or CR with incomplete peripheral count recovery (CRi) after induction.

Критерии исключения

Other Medical Conditions

• Isolated extramedullary disease.
• History or presence of clinically relevant central nervous system (CNS) pathology or event such as epilepsy, childhood or adult seizure, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, psychosis.
• Current autoimmune disease or history of autoimmune disease with potential CNS involvement.
• History of other malignancy within the past 3 years, except for malignancy treated with curative intent with low risk for recurrence. Exceptions include:

• Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease.
• Adequately treated cervical carcinoma in situ without evidence of disease.
• Adequately treated breast ductal carcinoma in situ without evidence of disease.
• Prostatic intraepithelial neoplasia without evidence of prostate cancer.
• Adequately treated urothelial papillary noninvasive carcinoma or carcinoma in situ.
• Known infection with human immunodeficiency virus (HIV) or chronic infection with hepatitis B or hepatitis C virus.
• Participant with symptoms and/or clinical signs and/or radiographic and/or sonographic signs that indicate an acute or uncontrolled chronic infection, any other concurrent disease or medical condition that could be exacerbated by the treatment or would seriously complicate compliance with the protocol.

Prior/Concomitant Therapy • Prior cancer chemotherapy/immunotherapy for this newly diagnosed B-ALL before the start of protocol-required therapy with the exception of intrathecal (IT) chemotherapy or pre-phase chemotherapy. Localized radiation for pain or disease control is allowed.

Prior/Concurrent Clinical Trial Experience

•Currently receiving a trial intervention, or less than 30 days or 5 half-lives if known (whichever is later) since ending a trial intervention in another investigational device or drug trial.

Other Exclusions

• History or evidence of any other clinically significant disorder, condition, or disease that, in the opinion of the investigator, would pose a risk to participant safety.
• Female participants of childbearing potential unwilling to use contraception.

• Male participants unwilling to abstain from donating sperm.
• Participant has known sensitivity to any of the products or components to be administered during dosing.
• Participant considered unlikely to be available to complete all protocol-required study visits or procedures, and/or to comply with all required study procedures (eg, Clinical Outcome Assessments) to the best of the participant and investigator's knowledge; exception - unavailability of a patient-reported outcome (PRO) in the participants' preferred/native language is not prohibitive to enrollment for eligible participants.
