Metronomic Treatment in Children and Adolescents With Recurrent or Progressive High Risk Neuroblastoma
- Conditions
- Recurrent Neuroblastoma
- Interventions
- Drug: metronomic therapy
- Registration Number
- NCT02641314
- Lead Sponsor
- University of Cologne
- Brief Summary
Neuroblastoma is the second most frequent cause for death from cancer in childhood. Already one year after diagnosis of recurrence from high risk neuroblastoma, 75% of the patients experience further progression.
Metronomic therapy is targeting not only the tumor cell, but also the tumor supplying vasculature and the interactions between Tumor and immune cells. The toxicity is expected to be low due to the low (but continuous) dosing of drugs.
The study investigates the tolerance and the efficacy of a new combination of five drugs consisting of propranolol (antiangiogenetic, anti-neuroblastic), Celecoxib (modulating immune response, ant-neuroblastic), cyclophosphamide (antiangiogenetic, anti-neuroblastic), etoposide (antiangiogenetic, anti-neuroblastic), and vinblastin (antiangiogenetic, anti-neuroblastic). Vinblastin is scheduled every 14 days intravenously, all other drugs are applied daily throughout 365 days (except etoposide for 4x3 weeks). The efficacies of each of the drugs have been demonstrated in vitro and in vivo in animal studies. All drugs have been used in children for other conditions. From those experiences low toxicities and a favorable Quality of life are expected.
- Detailed Description
Neuroblastoma relapses during or after intensive therapy most likely result from the presence of primary or acquired drug resistance. Therefore, new therapeutic modalities for salvage therapies are urgently needed.
The historical Kaplan-Meier curves of 218 unselected high risk patients after the first recurrence (from CR) or after the first progression (from PR/SD) demonstrate a 1 year event free survival rate of 25.2 ± 2.9% and a 1 year overall survival rate of 42.7 ± 3.3%.
Today cancer is widely considered as a multicomponent disease. One novel strategy likely to target the complexity of tumor cells and tumor environment is metronomic scheduling of anticancer treatment or "metronomic treatment" (MT). Low doses of chemotherapeutic drugs are continuously administered to cancer patients. The higher frequency and lower dose targets distinct aspects of cancer's functionality. Effects on tumor-angiogenesis, anti-cancer immunity and tumor stroma have been shown. Additionally low-dose metronomic treatment is often combined with modern antiinflammatory or antiangiogenic drugs, which specifically interact e.g. in tumor growth or angiogenesis pathways.
The rationale of this trial is the efficacy of metronomic therapy in heavily pre-treated refractory neuroblastoma patients.This trial protocol proposes a metronomic schedule of low dose chemotherapy with cyclophosphamide, etoposide and vinblastine, in combination with propranolol, a non-selective blocker of β adrenergic receptors and celecoxib, a selective cyclooxygenase type 2 (COX-2) inhibitor.
Patients enrolled in this study may benefit for two reasons. In the palliative situation, metronomic treatment may result in disease stabilization (SD) and a significant improvement of the quality of life (QOL) of patients e.g. by the decrease of pain through the treatment. For this reason, QOL including pain module is assessed as a separate secondary objective/ outcome measure. In the case of tumor response (PR, CR), the patients may qualify for a subsequent treatment approach aiming at further disease stabilization or even a long-term benefit.
