Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Male or female children and adolescents aged 2 to <18 years
- Written informed consent provided by parent(s)/legal representative(s) of the pediatric patient and patient's assent if appropriate
- Able to understand and/or follow study instructions alone or with parental assistance
- Diagnosed with the Ewing family of tumors or Rhabdomyosarcoma
- Scheduled to receive 1 of the following CTX regimens (inpatient or outpatient)
-
For the Ewing family of tumors:
- vincristine/ifosfamide/doxorubicin/etoposide (VIDE); with concomitant sodium 2-mercaptoethane sulfonate (MESNA) according to local standards
- vincristine/doxorubicin/cyclophosphamide alternating with ifosfamide/etoposide (VDC/IE); with concomitant MESNA treatment according to local standards
-
For rhabdomyosarcoma:
- vincristine/actinomycin/cyclophosphamide (VAC)
- vincristine/doxorubicin/cyclophosphamide alternating with ifosfamide/etoposide (VDC/IE); with concomitant MESNA treatment according to local standards
- Chemotherapy-naïve
- Body weight ≥15 kg
- White blood cell (WBC) count >2.5 x 109/L, absolute neutrophil count (ANC) ≥1.5 x 109/L, and platelet count ≥100 x 109/L (at screening and prior to CTX)
- For patients aged ≥12 years, Eastern Cooperative Oncology Group (ECOG) performance status ≤2 (See Appendix A.)
- Fertile patients (male or female) must use highly reliable contraceptive measures (i.e. two of the following: oral contraception, implants, injections, barrier contraception, and intrauterine device, or vasectomized/sterilized partners, or sexual abstinence). For purposes of this study, a fertile female patient is any female patient who has experienced menarche and who has not undergone tubal ligation.
- Female patients who have attained menarche must have a negative urine pregnancy test at the screening visit.
Exclusion Criteria:
- Previous exposure to filgrastim, pegfilgrastim or lenograstim or other G-CSFs in clinical development within 6 months prior to the XM22 administration
- Known hypersensitivity to filgrastim, pegfilgrastim or lenograstim or any other G-CSF in clinical development
- History of congenital neutropenia or cyclic neutropenia
- Any illness or condition that in the opinion of the Investigator may affect the safety of the patient or the evaluation of any study endpoint
- Pregnant or nursing women
- Fertile patients who do not agree to use highly reliable contraceptive measures during the entire duration of the study
- Prior bone marrow or stem cell transplant, or prior radiation to ≥25% of bone marrow (e.g. whole pelvic radiation) for any reason, or any therapeutic radiation within the 3 weeks prior to the XM22 dose
- Ongoing active infection or history of infectious disease within 2 weeks prior to the screening visit
- Treatment with lithium at screening or planned during the study.
