Stopped: Terminated by Amgen Limited
An add-on phase II trial within the ALL SCTped 2012 FORUM with the primary objective to determine whether the use of Blincyto in paediatric patients with B-lineage ALL and pre- and/or post-transplant MRD could induce MRD-negativity in patients who were MRD-positive before and/or after allogeneic HSCT. The study protocol entitled "A Phase II Study of Blincyto (Blinatumomab) in Children with CD19+ B-lineage Acute Lymphoblastic Leukemia (ALL) and Minimal Residual Disease (MRD)-Positivity before or following first Allogeneic Hematopoetic Stem Cell Transplantation (HSCT) in complete remission (CR1, CR2, CR3)" was included in the ALL SCTped 2012 FORUM Protocol Appendix 1b. According to protocol, 15 mcg/m2/day of Blincyto is given in continuous intravenous infusion over a 28-day cycle. Starting day for patients who are MRD-positive before HSCT is between day +60 and day +100 and for patients who become MRD-positive post HSCT it is between day +60 and day +360 post HSCT. Patients are evaluated for response at day +28 (+4 days) (bone marrow morphology and MRD analysis - defined by PCR/FLOW-techniques) after start of Blincyto-treatment at the end of first Blincyto infusion and at regular post-TX-checks (according to FORUM: days +28, +60, +100, +180 and +360 after HSCT). The protocol was approved in 10 countries (Austria, Belgium, Czech Republic, Denmark, France, Italy, Norway, Poland, Slovakia and Spain) participating ALL SCTped 2012 FORUM study. Overall, 3 patients were treated with Blincyto (2 in Oslo and 1 in Copenhagen). However, the Investigator Initiated Research Agreement was terminated by Amgen on 26 April 2022, leading to an early termination of the study, which was approved with the last protocol amendment.

Rate of MRD-negativity
Timeframe: Patients may receive 2 cycles of treatment. A single cycle of treatment is 28 days (4 weeks) of continuous infusion. Each cycle of treatment is separated by a 14 day (2 weeks) treatment-free interval.
