Maintenance Chemotherapy or Observation Following Induction Chemotherapy and Radiation Therapy in Treating Patients With Newly Diagnosed Ependymoma

November 20, 2023 updated by: Children's Oncology Group

Phase III Randomized Trial of Post-Radiation Chemotherapy in Patients With Newly Diagnosed Ependymoma Ages 1 to 21 Years

The primary aim of this randomized phase III trial was to study whether the addition of maintenance chemotherapy delivered after surgical resection and focal radiation would be better than surgery and focal radiation alone. The trial also studied if patients who received induction chemotherapy and then either achieved a complete response or went on to have a complete resection would also benefit from maintenance chemotherapy. Children ages 1-21 years with newly diagnosed intracranial ependymoma were included. There were 2 arms that were not randomized. One arm studied patients with Grade II tumors located in the supratentorial compartment that were completely resected. One arm studied patients with residual tumor and those patients all received maintenance chemotherapy after focal radiation. Chemotherapy drugs, such as vincristine sulfate, carboplatin, cyclophosphamide, etoposide, and cisplatin, 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. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving chemotherapy in combination with radiation therapy may kill more tumor cells and allow doctors to save the part of the body where the cancer started.

Detailed Description

PRIMARY OBJECTIVE:

I. To determine the event free survival (EFS) and overall survival (OS) of children with completely resected ependymoma treated with post-operative conformal radiation therapy (cRT) and then randomized to receive or not receive four cycles of post radiation maintenance chemotherapy (vincristine, cisplatin, etoposide and cyclophosphamide [VCEC]).

EXPLORATORY OBJECTIVES:

I. To estimate the EFS and OS of children with incompletely resected ependymoma who are unable to achieve a complete response (CR) by post-operative induction chemotherapy or by second surgery who will then be non-randomly assigned to cRT followed by four cycles of maintenance chemotherapy (VCEC).

II. To further evaluate the EFS and OS of children with supratentorial classic ependymoma who achieve a complete resection at first or second resection OR children who achieve a CR to short course induction chemotherapy following first surgery.

III. To evaluate whether the addition of maintenance chemotherapy post-radiation therapy contributes to neurobehavioral morbidity and reduced functional outcomes over time, compared to patients treated with radiation therapy followed by observation alone.

IV. To examine differences in neurobehavioral outcomes and quality of life of children treated with proton beam radiation therapy compared to children treated with conventional radiation delivery techniques.

V. To evaluate biologic prognostic factors in childhood ependymoma by studying molecular groups as defined by deoxyribonucleic acid (DNA) methylation profiling and immunohistochemistry, copy number variants to identify 1q gain in posterior fossa ependymomas, CDKN2A loss (homozygous deletion) in supratentorial ependymomas and specific genetic alterations such as RELA fusions, YAP1 fusions and the H3 K27M mutation on initial tumor samples and correlating these data with clinical outcome.

Va. To explore prognostic molecular signatures and genomic alterations in ependymomas by building upon the data derived from ACNS0121 to correlate biomarkers listed above with World Health Organization (WHO) grade, location, extent of resection, treatment, EFS and OS.

OUTLINE: This is a multicenter study partially randomized phase III study. Patients are randomized or non-randomly treated according to tumor location and extent of surgical resection or post-surgery induction chemotherapy response.

Arm I: Patients with classic histology(WHO Grade II) supratentorial ependymoma who have undergone microscopic gross total resection (GTR1) or achieved CR either after first or second resection or after post-operative induction chemotherapy are assigned to observation. For patients without GTR1, induction chemotherapy is comprised of vincristine intravenously (IV) over 1 minute on days 1 and 8 of cycles 1 and 2, carboplatin IV over 15-60 minutes on day 1 of cycles 1 and 2, and cyclophosphamide IV over 30-60 minutes on days 1-2 of cycle 1 only. Patients also receive etoposide IV over 60-120 minutes on days 1-3 of cycle 2 only. Cycle 1 continues for 3 weeks and cycle 2 continues for 4 weeks in the absence of disease progression or unacceptable toxicity.

ARM II: Patients with supratentorial ependymoma (Grade II without GTR1 or Grade III) or any infratentorial ependymoma who have undergone gross or near total resection (GTR or NTR) or achieved CR either after first or second resection or after post-operative induction chemotherapy are randomized to undergo conformal radiotherapy over 6-7 weeks followed by maintenance chemotherapy. Maintenance chemotherapy comprised of vincristine IV on days 1, 8, and 15 of cycles 1-3 only, etoposide IV over 60-120 minutes on days 1-3, cisplatin IV over 1-8 hours on day 1, and cyclophosphamide IV over 30-60 minutes on days 2-3. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients without GTR or NTR at enrollment require induction chemotherapy (see Arm I) and possibly second surgery before randomization.

ARM III: Patients with supratentorial ependymoma (Grade II without GTR1 or ST Grade III) or any infratentorial ependymoma (Grade II or III) who have undergone gross or near total resection or achieved CR either after first or second resection or after post-operative induction chemotherapy are randomized to undergo conformal radiotherapy over 6-7 weeks and then undergo observation. Patients without GTR or NTR at enrollment require induction chemotherapy (see Arm I) and possibly second surgery before randomization.

ARM IV: Patients with subtotal resection after induction chemotherapy (see Arm I) and second surgery are non-randomly assigned to Arm II treatment.

After completion of study therapy, patients are followed up every 4 months for 5 years, and then annually thereafter.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

1 year to 21 years (Child, Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients must be newly diagnosed with histologically confirmed intracranial ependymoma; patients with classic ependymoma (WHO II) or anaplastic ependymoma (WHO III) are eligible, as are various subtypes described as clear cell, papillary, cellular or a combination of the above
  • There is no minimum performance level; children with ependymoma may suffer neurologic sequelae as a result of their tumor or surgical measures taken to establish a diagnosis and resect the tumor; in the majority of cases, there is neurologic recovery; neurologic recovery is not likely to be impeded by protocol therapy
  • REGULATORY: All patients and/or their parents or legal guardians must sign a written informed consent
  • REGULATORY: All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met

Exclusion Criteria:

  • Patients with evidence of metastatic disease will be excluded; any evidence of non-contiguous spread beyond the primary site as determined by pre or post-operative magnetic resonance (MR) imaging of brain, pre or post-operative MR imaging of the spine, and post-operative cerebrospinal fluid (CSF) cytology obtained from the lumbar CSF space (the requirement for lumbar CSF examination may be waived if deemed to be medically contraindicated); CSF cytology from a ventriculostomy or permanent ventriculoperitoneal (VP) shunt that reveals the presence of tumor cells is indicative of metastatic disease
  • Patients with a diagnosis of spinal cord ependymoma, myxopapillary ependymoma, subependymoma, ependymoblastoma, or mixed glioma are NOT eligible
  • No prior treatment other than surgical intervention and corticosteroids; patients are allowed to have had more than one attempt at resection prior to enrollment

Participant Group / Arm
Intervention / Treatment
Experimental: Arm I (chemotherapy, observation)
Patients with classic histology(WHO Grade II) supratentorial ependymoma who have undergone microscopic gross total resection (GTR1) or achieved CR either after first or second resection or after post-operative induction chemotherapy are assigned to observation. For patients without GTR1, induction chemotherapy is comprised of vincristine intravenously (IV) over 1 minute on days 1 and 8 of cycles 1 and 2, carboplatin IV over 15-60 minutes on day 1 of cycles 1 and 2, and cyclophosphamide IV over 30-60 minutes on days 1-2 of cycle 1 only. Patients also receive etoposide IV over 60-120 minutes on days 1-3 of cycle 2 only. Cycle 1 continues for 3 weeks and cycle 2 continues for 4 weeks in the absence of disease progression or unacceptable toxicity.
