New chemo timing strategies aim to outsmart aggressive childhood cancer
NCT ID NCT04388839
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests four different chemotherapy schedules in children and adults with a rare, aggressive muscle cancer that has spread. Participants choose from a first-strike approach, a first-strike followed by maintenance, an adaptive schedule, or standard chemo. The goal is to see which timing works best to delay cancer return and improve survival.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Participants must have a new histologic diagnosis of rhabdomyosarcoma * Participants must have FISH, PCR or other molecular confirmation of PAX/FOXO1 fusion per institutional standards * Participants must have sufficient tissue (up to 10 unstained FFPE) for correlative testing * All participants must have distant metastatic disease; either biopsy positive or PET avid extranodal or distant nodal lesions determined by the investigator to be metastatic disease. Patients with a single distant metastatic site that has been excised prior to study entry are eligible * No prior systemic chemotherapy * Participants enrolled to Arm B, maintenance, must be able to take oral cyclophosphamide. Note: enteral administration of cyclophosphamide is allowable. * Males and females of reproductive potential may not participate unless they have agreed to the use of, at minimum, two methods of contraception during and after treatment or abstinence. * Women of childbearing potential should adhere to contraception for a period of 4 months after completion of systematic chemotherapy administration * Men who are sexually active with women of child bearing potential should adhere to contraception for a period of 4 months after completion of systematic chemotherapy administration * All patients and/or their parents or legal guardians must have the ability to understand and the willingness to sign a written informed consent or assent document. Exclusion Criteria: * Participants with regional lymph nodes as the only site of disease are not eligible. Distant nodal sites alone are eligible * Participants who are receiving any other investigational agents for rhabdomyosarcoma are ineligible * Participants must not be receiving any additional medicines being given for the specific purpose of treating cancer. Alternative medications including, but not limited to cannabis based products would not be a reason for exclusion * Participants are ineligible if they have uncontrolled intercurrent illness including, but not limited to: * ongoing or active infection not expected to resolve with current antibiotic plan * cardiac arrhythmia * psychiatric illness/social situations that would limit compliance with study requirements * Patients who are pregnant or breastfeeding are not eligible because there is no available information regarding human fetal or teratogenic toxicities. Females of childbearing potential must have a negative serum or urine pregnancy test within 24 hours of starting protocol therapy. * Participants who are considered unable to comply with the safety monitoring requirements of the study are not eligible
