Vincristine and Irinotecan With or Without Temozolomide in Children and Adults With Refractory/Relapsed Rhabdomyosarcoma

Phase 2
Completed
Conditions
RHABDOMYOSARCOMA
Interventions
Drug: Vincristine, Irinotecan
Drug: Vincristine, Irinotecan, Temozolomide
Registration Number
NCT01355445
Lead Sponsor
Centre Oscar Lambret
Brief Summary

This is an international open-label, randomized, multicenter phase II study of VIT and VI for the treatment of patients with recurrent or refractory rhabdomyosarcoma. The study will evaluate the safety and efficacy of these combinations in patients with recurrent or refractory rhabdomyosarcoma.

Detailed Description

The dose of vincristine will be 1.5 mg/m² or 0.05 mg/kg for patient ≤ 10 kg (maximum 2 mg) and will be administered by direct intravenous infusion on day 1 and 8 of each course, before irinotecan.

The dose of irinotecan will be 50 mg/m²/d. Irinotecan will be given intravenously over 1 hour on days 1-5 of each course, one hour following the administration of temozolomide.

In the absence of any contraindication (ie known allergies), treatment with oral cefixime 8 mg/kg once daily (maximum daily dose 400 mg) is recommended and will be started 2 days before chemotherapy until day 7.

Temozolomide will be given according to the randomization. The starting dose of temozolomide will be 125 mg/m²/d. The dose of temozolomide will be escalated to 150 mg/m²/day at cycle 2 for patients who do not experience \> grade 3 toxicity of any kind. Temozolomide will be given orally, on an empty stomach, on days 1 through 5 of each course.

Dose reductions and/or administration delays will be performed using specific predefined rules to accommodate individual patient tolerance of treatment and to maintain optimal dose intensity.

    • Patient affiliated with a health insurance system. Applicable for French patients only Written informed consent of patient and/or parents/guardians

  • PRIOR or CONCURRENT THERAPY :

    • More than 3 weeks since prior radiation therapy to the site of any progressive lesion that will be identified as a target lesion to measure tumor response
    • At least 3 weeks since prior myelosuppressive therapy (6 weeks for nitrosourea. 2 weeks for vincristine, vinblastine, vinorelbine or low dose cyclophosphamide)
    • No concurrent enzyme-inducing anticonvulsants (EIAC), including phenytoin, phenobarbital or carbamazepine

Primary Outcome Measures
NameTimeMethod
Objective tumour response and progression in each treatment arm.at least 6 weeks (two cycles of treatment)

The primary efficacy endpoint is defined as the proportion of patients who had a documented complete or partial tumour response occurring after the first 2 cycles of treatment which must be confirmed by a follow-up objective tumour assessment obtained within 4-5 weeks after the initial documentation.

Secondary Outcome Measures
NameTimeMethod
To assess the duration of tumor response in each treatment armDuring all the study

The duration of tumour response is defined as the time from first documentation of objective tumour response to the first objective or clinical documentation of progression

To determine the time to tumor progression in each treatment armDuring all the study

The time to tumor progression: the time from the date of first treatment administration to the date of first objective or clinical documentation of tumour progression or death due to any cause

To assess the time to treatment failure in each treatment armBefore 1 year

The time to treatment failure is defined as the time from the date of first treatment administration to the first documentation of tumour progression, discontinuation of study treatment before one year, or death, whichever occurs first

To assess the overall survival in each treament armDuring all the study

The overall survival is defined as the time from the date of first treatment administration to date of death

To assess the safety profile and tolerability in each treatment armDuring all the study

Safety parameters include adverse events and haematology and blood chemistry assays.

Safety evaluations will include characterization of the frequency and severity of adverse events, complete blood cell counts with differential, serum chemistries and electrolytes, and change in weight and body surface area (BSA).
