Interventions

  • Apatinib, Irinotecan, Temozolomide — DRUG
    In the Phase I stage, apatinib was administered using a 3+3 dose escalation design with three dose cohorts. The IT regimen was maintained at fixed doses, with patients receiving up to 8 cycles of chemotherapy. The recommended Phase II dose (RP2D) was determined from the Phase I dose-escalation phase. In the Phase II stage, the study included an apatinib combination therapy phase and an apatinib maintenance therapy phase. During the combination therapy phase, apatinib was administered at the RP2D in combination with the IT regimen (at fixed doses) for up to 8 cycles. In the maintenance therapy phase, apatinib was administered orally as a single agent at the RP2D until disease progression or intolerable toxicity occurred.

Study Details

The survival rate of recurrent and refractory neuroblastoma is low and the prognosis is poor. Apatinib mesylate is a highly selective small-molecule vasoendothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor. Apatinib mesylate has been shown to be safe and effective in recurrent or refractory pediatric neuroblastoma in Sun Yat-sen University Cancer Center. Apatinib mesylate combined with IT regimen is expected to further improve the efficacy and survival rate of recurrent or refractory neuroblastoma.

Arms

  • Experimental: The first dose level
    The first dose level of apatinib combined with fixed-dose 5-day courses of irinotecan (50 mg/m²/dose infused IV 90 min) plus temozolomide (150 mg/m²/dose infused IV 90 min) for up to 8 courses.
  • Experimental: The second dose level
    The second dose level of apatinib combined with fixed-dose 5-day courses of irinotecan (50 mg/m²/dose infused IV 90 min) plus temozolomide (150 mg/m²/dose infused IV 90 min) for up to 8 courses.
  • Experimental: The third dose level
    The third dose level of apatinib combined with fixed-dose 5-day courses of irinotecan (50 mg/m²/dose infused IV 90 min) plus temozolomide (150 mg/m²/dose infused IV 90 min) for up to 8 courses.
  • Experimental: Phase 2: The RPIID group
    Based on the Phase I stage of apatinib, the recommended phase II dose was administered in combination with the IT regimen every three weeks for up to 8 cycles, followed by maintenance therapy with apatinib until tumor progression recurrence or unacceptable toxicity.
