Summary

The purpose of this study is to investigate whether Bevacizumab (an anti-VEGF monoclonal antibody) added to a backbone chemotherapy regimen (Temozolomide, Irinotecan-Temozolomide or Topotecan-Temozolomide) demonstrates activity in children with relapsed or refractory neuroblastoma. Also, to investigate whether the addition of Irinotecan or Topotecan to Temozolomide increases the activity of chemotherapy.The primary objective of the study is the best response (Complete Response or Partial Response) while trial treatment, within 18 or 24 weeks depending on the arm of the trial the participant is randomised to. Secondary endpoints are assessing the side effects, the length of time before progression (Progression Free Survival) and overall survival (OS).

This trial will address two important questions:

  • does targeting blood vessel development using bevacizumab, (a monoclonal antibody against the Vascular Endothelial Growth Factor (VEGF)), add to the effect on a tumour when used with existing chemotherapy, compared to the effect of the existing chemotherapy alone (temozolomide)? NOTE- This question has been completed.
  • does the addition of a second chemotherapy drug (irinotecan or topotecan) increase the effect on a tumour compared to the effect of one alone (temozolomide) NOTE - This question has been completed.
  • does the addition of dinutuximab beta added to a backbone chemotherapy (temozolomide or temozolomide + topotecan) increase the effect of backbone alone.

Patients aged 1-21 years of age with relapsed or refractory high-risk neuroblastoma are randomised to one of two treatment arms: temozolomide-topotecan (TTo) or dinutuximab beta-temozolomide-topotecan (dBTTo). Temozolomide (T), irinotecan-temozolomide (IT), bevacizumab-T (BT), BIT (bevacizumab-IT), bevacizumab-temozolomide-topotecan (BTTo) and dinutuximab beta-temozolomide (dBT) are now closed to recruitment.

Description

This is an international open-label, randomised, multicentre phase II trial of temozolomide irinotecan, with or without bevacizumab, for the treatment of patients with relapsed or refractory neuroblastoma. The study will evaluate the safety and activity of these combinations.

Patients will be registered into the trial and randomised at the same time to one of the following two arms (approximately 30 patients per arm):

TTo: Temozolomide + Topotecan dBTTo: Dinuximab beta + Temozolomide + Topotecan

Arms which have now closed to recruitment:

dBT: Dinutuximab beat + Temozolomide Closed 28 ]Jan 2020 T: Temozolomide - Closed 28 Jan 2020 BT: Bevacizumab + Temozolomide - Closed 7 Feb 2019 IT: Irinotecan + Temozolomide - Closed 21 June 2018 BIT: Bevacizumab + Irinotecan + Temozolomide - Closed 21 June 2018 BTTo: Bevacizumab + Temozolomide + Topotecan - Closed 7 Feb 2019

Randomisation will be via a secure on-line computer-based system at the Cancer Research Clinical Trial Unit (CRCTU), University of Birmingham, United Kingdom (UK) and patients will be allocated in a 2:1 ratio. Minimisation will be used to ensure balance across the arms for the important prognostic factors as described by London et al. [10]: a) relapsed, refractory disease, b) early (< 18 months), late relapse (18 months) and c) measurable versus evaluable disease (i.e. disease evaluated according to RECIST versus disease detectable only by MIBG scanning with or without bone marrow involvement as detected by local morphology) Patients will receive treatment for 6 courses, lasting 24 weeks.

Patients with a response (CR, PR) or stable disease (SD) while on the BEACON-Neuroblastoma trial will receive 6 cycles of trial treatment. If the patient has achieved a satisfactory response (i.e. CR, PR or SD) with acceptable toxicity, treatment may be extended beyond 6 cycles (up to 12 cycles) after discussion with the Sponsor and the Chief Investigator (CI).

In addition, patients randomised to TTo may recieve an optional regimen of dinutuximab beta + topotecan + cyclophosphamide (up to 6 cycles).

Relapsed: any relapsed or progressed high-risk neuroblastoma
Refractory high risk disease: Lack of adequate response to frontline therapy that precludes the patient from proceeding to consolidation therapies
Measurable disease by cross sectional imaging (RECIST) or evaluable disease
Age 1 to 21 years
Informed consent from patient, parent or guardian
Performance Status:Lansky 50%, Karnofsky 50% or Eastern Cooperative Oncology Group 3 (Patients who are unable to walk because of paralysis, but who are able to sit upright unassisted in a wheelchair, will be considered ambulatory for the purpose of assessing performance score)
Life expectancy of 12 weeks
No bone marrow disease: Platelets 75 x 10^9/L (unsupported for 72 hours), absolute neutrophil count 0.75 x10^9/L (no G-cerebrospinal fluid support for 72 hours), Haemoglobin 8 g/dL (transfusions allowed) Bone marrow disease: Platelets 50 x10^9/L (unsupported for 72 hours), absolute neutrophil count (ANC) 0.5 x 10^9/L (no granulocyte colony stimulating factor (G-CSF) for 72 hours), Haemoglobin 8 g/dL (transfusions allowed)
