Официальное название

MEPENDAX: Phase I/II Study of Axitinib (Inlyta®) and Oral Metronomic Etoposide for Pediatric Children and AYA Refractory/Relapsing Medulloblastoma and Ependymoma

Обзор

It is an open multicentric phase I/II trial with axitinib (Inlyta®) and metronomic delivery of etoposide for children, adolescent and young adults (AYA) with refractory/ relapsing solid tumors. It is a two-stage trial: First stage: To determine the Maximum Tolerated Dose (MTD) of the combination of axitinib and oral metronomic etoposide for patient with medulloblastoma or ependymoma Second stage: Extension cohort evaluating the preliminary efficacy at the recommended dose for the phase II (RDP2) of the combination. The 2nd stage will start after a meeting of independent data monitoring committee (IDMC). Two cohorts of 9 patients with ependymoma and medulloblastoma Patients treated at first stage won't be included in the second stage.

• Hemoglobin ≥ 8.0 g/dL (transfusion is allowed) Cardiac function
• Shortening fraction (SF) >29% and left ventricular ejection fraction (LVEF) ≥50% at baseline, as determined by echocardiography (mandatory only for patients who have received cardiotoxic therapy).

Renal and hepatic function

• Total bilirubin < 1.5 x ULN
• Alanine aminotransferase (ALT)/ Aspartate aminotransferase (AST)/ < 2.5 x ULN

• Able to comply with scheduled follow-up and with management of toxicity.
• Females of child bearing potential must have a negative serum pregnancy test within 7 days prior to initiation of treatment.
• Sexually active patients must agree to use adequate and appropriate contraception (in accordance with Clinical Trials Facilitation and Coordination Group (CTFG) recommendations) while on study drug and for 6 months after stopping the study drug.
• Patient able to comfortably swallow capsules.

• Patient affiliated to a social security regimen or beneficiary of the same according to local requirements.

Non-inclusion Criteria

• Chemotherapy within 21 days of day 1 from the start of study treatment. This period can be shortened in the case of treatment with vincristine (2 weeks) and extended to 6 weeks in the case of treatment with nitrosureas. The period is set to 5 half-lives in the case of targeted therapies or metronomic chemotherapy. The period is set to 2 weeks after bevacizumab administration. Evidence of > Grade 1 recent CNS hemorrhage on the baseline MRI or scan.
• Impairment of gastrointestinal (GI) function or GI disease that may significantly alter drug absorption of oral drugs (e.g., ulcerative diseases, uncontrolled nausea, vomiting, diarrhea, or malabsorption syndrome).

• Known active viral hepatitis or known human immunodeficiency virus (HIV) infection or any other uncontrolled infection.
• Presence of any NCI-CTCAE v5 grade ≥ 2 treatment-related extra-hematological toxicity with the exception of alopecia, ototoxicity or peripheral neuropathy.
• Known congenital immunodeficiency.
• Radiotherapy within the 2 months preceding D1 of the start of study treatment. Palliative RT on a non-target lesion is allowed up to 1 weeks before beginning of treatment.
• Major surgery within 21 days of the first dose. Gastrostomy, ventriculo-peritoneal shunt, endoscopic ventriculostomy, tumor biopsy and insertion of central venous access devices are not considered major surgery, but for these procedures, a 48 hour interval must be maintained before the first dose of the investigational drug is administered.
• Bleeding disorder.
