Conditions: Sarcoma
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 154
Healthy volunteers: no

Brief summary:
This open-label two-arm study will assess the safety and efficacy of a combination of bevacizumab + standard chemotherapy with standard chemotherapy alone as active comparator in childhood and adolescent patients with metastatic rhabdomyosarcoma or non-rhabdomyosarcoma soft tissue sarcoma. Patients will be randomized to receive bevacizumab + standard chemotherapy or standard chemotherapy alone. Treatment will consist of 9 x 3-week cycles of induction treatment (standard chemotherapy with or without bevacizumab 7.5 mg/kg iv on day 1 of each cycle) followed by 12 x 4-week cycles of maintenance treatment (standard chemotherapy with or without bevacizumab 5 mg/kg iv on days 1 and 15 of each cycle). The anticipated time on study treatment is 1-2 years.

Detailed description:

Arms:
arm 1: Participants received continuous IV infusion of bevacizumab (7.5 mg/kg every 3 weeks) on Day 1 of 3-week cycles followed by induction chemotherapy (4 cycles of IVADo-containing chemotherapy followed by 5 cycles of IVA-containing chemotherapy) as per institutional practice for a total of 9 cycles during induction treatment phase. As per the investigator decision, local therapy (radiotherapy and /or surgery) was expected to start after 4 weeks of the last bevacizumab administration in the induction phase and resumed to bevacizumab in the maintenance phase at least 4 weeks after the last dose of local therapy. During maintenance treatment phase, participants received IV infusion of bevacizumab (5 mg/kg every 2 weeks) followed by vinorelbine- and cyclophosphamide-containing chemotherapy (as per institutional practice) on Days 1 and 15 of 4-week cycles for a total of 12 cycles. arm 2: Participants received 9 cycles of induction chemotherapy (4 cycles of IVADo-containing chemotherapy followed by 5 cycles of IVA-containing chemotherapy administered every 3 weeks as per institutional practice. As per the investigator evaluation, participants had option to undergo local therapy (radiotherapy and /or surgery) during last 3 cycles of IVA (i.e. from Cycle 6 to Cycle 9). During maintenance treatment phase, participants received vinorelbine- and cyclophosphamide-containing chemotherapy (as per institutional practice) on Day 1 and 15 of 4-week cycles for a total of 12 cycles.

Interventions: intervention 1: Standard chemotherapy intervention 2: bevacizumab [Avastin]
Intervention descriptions: intervention 1: As prescribed intervention 2: 7.5 mg/kg iv on day 1 of 9 x 3-week cycles, followed by 5 mg/kg iv on days 1 and 15 of each 4-week cycle
