RECRUITINGPhase 2INTERVENTIONAL

A Study of Combination Chemotherapy for Patients With Newly Diagnosed DAWT and Relapsed FHWT

Treatment of Newly Diagnosed Diffuse Anaplastic Wilms Tumors (DAWT) and Relapsed Favorable Histology Wilms Tumors (FHWT)

A Study of Combination Chemotherapy for Patients With Newly Diagnosed DAWT and Relapsed FHWT (NCT04322318) is a Phase 2 interventional studying Anaplastic Kidney Wilms Tumor and Recurrent Kidney Wilms Tumor, sponsored by Children's Oncology Group.

About This Trial

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).

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Anaplastic Kidney Wilms Tumor and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 256 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Anaplastic Kidney Wilms Tumor subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: - Patients with newly diagnosed stages 2 - 4 diffuse anaplastic Wilms tumor must be enrolled on APEC14B1, consented to Part A - Eligibility Screening, and have received an initial stratum assignment showing DAWT (if anaplasia first identified at diagnostic, pre-treatment nephrectomy or biopsy) or a final stratum assignment showing DAWT (if anaplasia first noted at delayed nephrectomy) prior to enrollment on AREN1921. Prior enrollment on APEC14B1 is not an eligibility requirement for patients with relapsed favorable histology Wilms tumor. - Patients must be =\< 30 years old at study enrollment - Patients with the following diagnoses are eligible for this study: - Newly diagnosed stages 2 - 4 diffuse anaplastic Wilms tumor as confirmed by central review - Favorable histology Wilms tumor at first relapse. Relapsed FHWT patients must have previously achieved remission for their initial FHWT diagnosis to be eligible for this study. The relapse risk groups are defined as follows, regardless of radiation therapy: - Standard-Risk relapse: Patients who received two chemotherapy agents for frontline therapy; primarily actinomycin D and vincristine - High-Risk relapse: Patients who received three chemotherapy agents for frontline therapy; primarily vincristine, actinomycin D and doxorubicin or vincristine, actinomycin D and irinotecan - Very High-Risk relapse: Patients who received four or more chemotherapy agents as part of initial therapy; primarily regimen M or its variations - Patients with newly diagnosed DAWT must have had histologic verification of the malignancy. For relapsed FHWT patients, biopsy to prove recurrence is encouraged, but not required - Note: For relapsed FHWT patients, an institutional pathology report confirming favorable histology Wilms tumor (from relapse, if available, or from original diagnosis) must be available for upload prior to initiation of protocol therapy ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Who can participate in NCT04322318?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

How do I contact the trial site for NCT04322318?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
