Clinical Trial Summary

This phase II trial studies how well combination chemotherapy works in treating patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) or favorable histology Wilms tumors (FHWT) that have come back (relapsed). Drugs used in chemotherapy regimens such as UH-3 (vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan) and ICE/Cyclo/Topo (ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan) work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may help doctors find out what effects, good and/or bad, regimen UH-3 has on patients with newly diagnosed DAWT and standard risk relapsed FHWT (those treated with only 2 drugs for the initial WT) and regimen ICE/Cyclo/Topo has on patients with high and very high risk relapsed FHWT (those treated with 3 or more drugs for the initial WT).

Description:

PRIMARY OBJECTIVES: I. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/ carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the event-free survival (EFS) of patients with newly diagnosed stage 4 diffuse anaplastic Wilms tumor (DAWT) as compared to historical controls. II. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the EFS of patients with standard-risk relapsed favorable histology Wilms tumor (SRrFHWT) as compared to historical controls. SECONDARY OBJECTIVES: I. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the overall survival (OS) of patients with newly diagnosed stage 4 DAWT as compared to historical controls. II. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the OS of patients with SRrFHWT as compared to historical controls. III. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the EFS and OS of patients with newly diagnosed stage 2 and 3 DAWT as compared to historical controls. IV. To establish EFS and OS for high-risk (HRrFHWT) and very high risk (VHRrFHWT) relapsed favorable histology Wilms tumor treated with ifosfamide/carboplatin/etoposide alternating with cyclophosphamide/ topotecan. EXPLORATORY OBJECTIVES: I. To describe renal toxicity of ifosfamide/carboplatin/etoposide in HRrFHWT and VHRrFHWT patients using conventional and novel biomarkers of renal toxicity (urine NGAL, cystatin C and Kim1) in the context of the chemotherapy regimens used on this study. II. To collect and bank serial blood and urine samples in patients with newly diagnosed DAWT or relapsed FHWT and tumor tissue in patients with relapsed FHWT, for future analysis. III. To assess the impact of p53 gene and protein expression on outcome for patients with newly diagnosed DAWT. IV. To determine EFS/OS in the subsets of patients with newly diagnosed DAWT or relapsed FWHT who undergo gross total resection at all disease sites at diagnosis or after neoadjuvant chemotherapy. V. To describe the rate of regional lymph node sampling at the time of nephrectomy with the use of a pre-operative surgical checklist for patients with newly diagnosed DAWT. VI. To determine the feasibility of intensity modulated radiation therapy (IMRT) with central quality assurance (QA) monitoring to reduce radiation induced toxicity to the heart, thyroid, breast and solitary kidney for children with lung and liver metastases (part of an overarching aim in this study and across frontline favorable histology Wilms tumor studies). OUTLINE: Patients are assigned to 1 of 2 arms. ARM I (REGIMEN UH-3): CYCLES 1, 5, 7, 10, AND 13: Patients receive vincristine intravenously (IV) via minibag per institutional policy on days 1, 8, and 15. Patients also receive doxorubicin IV over 1-15 minutes and cyclophosphamide IV over 30-60 minutes on day 1.

CYCLES 3, 4, 8, AND 11: Patients receive vincristine IV via minibag per institutional policy on days 1 and 8 and irinotecan IV over 90 minutes on days 1-5. Treatment repeats every 21 days during cycles 3, 4, 8, and 11 in the absence of disease progression or unacceptable toxicity. Patients undergo radiation therapy (RT) at week 7 of cycle 3 as clinically indicated. Patients undergo a computed tomography (CT) scan, a positron emission tomography (PET) scan, a chest x-ray, magnetic resonance imaging (MRI), an abdominal ultrasound, and/or a bone scan throughout the trial. Patients may also undergo blood specimen collection and biopsy throughout the trial.

Patients also receive etoposide IV over 1-2 hours and ifosfamide IV over 2-4 hours on days 1-3. Treatment repeats every 21 days during cycles 1, 2, 4, 5, 7, and 9 in the absence of disease progression or unacceptable toxicity. CYCLES 3, 6, 8, AND 10: Patients receive cyclophosphamide IV over 15-30 minutes and topotecan IV over 30 minutes on days 1-5. Treatment repeats every 21 days during cycles 3, 6, 8, and 10 in the absence of disease progression or unacceptable toxicity. Patients undergo surgery and/or RT during cycles 4, 7, and 10 as clinically indicated. Patients undergo a CT scan, a PET scan, a chest x-ray, MRI, an abdominal ultrasound, and/or a bone scan throughout the trial. Patients may also undergo blood specimen collection and biopsy throughout the trial. After completion of study treatment, patients are followed up every 3 months for years 1-2, every 6 months for years 3-4, and once at year 5.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Incidence of grade 3-5 renal toxicity	Incidence of grade 3-5 renal toxicity during protocol therapy will be monitored for Stratum 4 as part of a prospective safety monitoring plan. At the time of final study analysis, renal toxicity will be described by factors including age, relapse risk group, and timing and association (descriptive) with the exploratory renal toxicity biomarkers.	Up to 30 weeks on average for Stratum 4 only
Other	Collection of blood and urine samples	For all Strata 1-4, serial blood and urine samples will be collected (during protocol therapy, at the end of protocol therapy, and at first relapse) and banked for future analysis such as evaluation of minimal residual disease by assessing levels of circulating tumor-derived deoxyribonucleic acid.	Up to 42 weeks on average for Strata 1-3 and up to 30 weeks on average for Stratum 4
Other	p53 biomarker analysis	For patients with diffuse anaplastic Wilms tumors (DAWT) (Strata 1 and 2), p53 from diagnostic tissue will be assessed, and rates of p53 mutations described overall and within each stratum. Degree of anaplasia as a predictor of p53 mutation status will be analyzed in logistic regression models, and association of p53 status with EFS and OS will be analyzed in Cox regression models, stratified by disease stage. Possible interactions between p53 mutation status and degree of anaplasia in outcome models will be explored.	Based on tissue collected at diagnosis (Strata 1 and 2 only), with outcomes collected up to 5 years after study entry
Other	EFS for patients with gross total disease resection	EFS will be described for newly diagnosed disease stage 2-4 DAWT patients (Strata 1 and 2) and relapsed favorable histology Wilms tumors (FHWT) patients (Strata 3 and 4) who have gross total disease resection prior to enrollment or at the time of delayed nephrectomy following adjuvant chemotherapy. Kaplan-Meier curves will be reported by strata with 95% confidence bands. Potential prognostic factors for these patients will be explored in Cox regression models.	From study entry to the earliest of relapse or disease progression, second malignant neoplasm, or death from any cause, assessed up to 5 years after study enrollment
Other	OS for patients with gross total disease resection	OS will be described for newly diagnosed disease stage 2-4 DAWT patients (Strata 1 and 2) and relapsed FHWT patients (Strata 3 and 4) who have gross total disease resection prior to enrollment or at the time of delayed nephrectomy following adjuvant chemotherapy. Kaplan-Meier curves will be reported by strata with 95% confidence bands. Potential prognostic factors for these patients will be explored in Cox regression models.	From study entry to death due to any cause, assessed up to 5 years after study entry
Other	Association of the number of nodes examined with EFS and OS	The number of lymph nodes examined at the time of primary nephrectomy and number of positive nodes will be collected for all DAWT patients who enroll to Strata 1 or 2. The association of the number of nodes examined with EFS and OS will be explored in Cox regression models stratified by disease stage. For each of these analyses, association will be expressed either as a single hazard ratio if the effect is found to be linear, or as continuous functions on the hazard ratio scale if the effect is found to be non-linear. Similar models will be fit to examine the association between ratio of positive nodes to nodes examined and outcomes. Confidence intervals or bands will be reported for all quantities.	Nodal information from upfront or delayed nephrectomy, with outcomes collected for up to 5 years after study entry
Primary	Event-free survival (EFS)	For Strata 1-3, the primary analysis of EFS will consist of a one-sample, one-sided log rank test versus a historical control cohort (or representative distribution) with stratum-specific type I error levels. For Stratum 4, the primary analysis of EFS is descriptive, but with a desired level of precision to estimate 4-year EFS at the time of the final analysis (2 years after the last patient enrolls).	From study entry to the earliest of relapse or disease progression, second malignant neoplasm, or death from any cause, assessed up to 5 years after study enrollment
Secondary	Overall survival (OS)	For each stratum, OS will be estimated at the same time as the conclusive (interim or final) analysis and reported descriptively with 95% pointwise confidence bands.	From study entry to death due to any cause, assessed up to 5 years after study enrollment
