E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to assess the pharmacokinetics (PK) of a single subcutaneous (SC) injection of XM22, 100 μg/kg body weight (BW), in children with Ewing family of tumors or rhabdomyosarcoma. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to assess the pharmacodynamics (PD), efficacy, safety, tolerability, and immunogenicity of this single dose in the same patient population. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female children and adolescents aged 2 to <18 years
2. Written informed consent provided by parent(s)/legal
representative(s) of the pediatric patient and patient's assent if
appropriate, before screening procedures are initiated
3. Able to understand and/or follow study instructions alone or with parental assistance
4. Diagnosed with the Ewing family of tumors or rhabdomyosarcoma
5. Scheduled to receive 1 of the following chemotherapy regimens
(inpatient or outpatient)
• For the Ewing family of tumors:
- vincristine/ifosfamide/doxorubicin/etoposide (VIDE); concomitant treatment with sodium 2-mercaptoethane sulfonate (MESNA) according to local standards
- vincristine/doxorubicin/cyclophosphamide alternating with
ifosfamide/etoposide (VDC/IE); concomitant treatment with MESNA according to local standards
• For rhabdomyosarcoma:
- vincristine/actinomycin/cyclophosphamide (VAC); concomitant treatment with MESNA according to local standards
- vincristine/doxorubicin/cyclophosphamide alternating with
ifosfamide/etoposide (VDC/IE); concomitant treatment with MESNA according to local standards
-ifosfamide, vincristine and actinomycin D (IVA); concomitant treatment with MESNA according to local
standards
6. Body weight ≥15 kg for the 2 highest age strata and ≥12.5 kg for patients in the lowest age stratum
8. White blood cell (WBC) count >2.5 x 10(9)/L, absolute neutrophil count (ANC) ≥1.5 x 10(9)/L, and platelet count ≥100 x 10(9)/L (at screening and prior to CTX).
9. For patients aged ≥12 years, Eastern Cooperative Oncology Group (ECOG) performance status ≤2
10. 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.
11. Female patients who have attained menarche must have a negative urine pregnancy test at the screening visit.

E.4 | Principal exclusion criteria |
1. Previous exposure to filgrastim, pegfilgrastim or lenograstim or
other G-CSFs in clinical development within 6 months prior to the XM22 administration
2. Known hypersensitivity to filgrastim, pegfilgrastim or lenograstim or any other G-CSF in clinical development
3. History of congenital neutropenia or cyclic neutropenia
4. 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
5. Pregnant or nursing women
6. Fertile patients who do not agree to use highly reliable contraceptive measures during the entire duration of the study
7. Prior bone marrow or stem cell transplant, or prior radiation to ≥25% of bone marrow (eg, whole pelvic radiation) for any reason, or any therapeutic radiation within the 3 weeks prior to the XM22 dose
8. Ongoing active infection or history of infectious disease within 2
weeks prior to the screening visit
9. Treatment with lithium at screening or planned during the study. |
