About this study
The purpose of this study is to establish the safety and tolerability of simultaneous infusions of 5-Azacytidine and trastuzumab into the fourth ventricle of the brain or resection cavity in patients with recurrent posterior fossa ependymoma and to assess the antitumor activity of simultaneous infusions of 5-Azacytidine and trastuzumab into the fourth ventricle of the brain or resection cavity in patients based upon imaging studies and lumbar cerebrospinal fluid (CSF) cytology.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
5-Azacytidine and trastuzumab infusionDrug
Patients will receive once weekly 10 mg intraventricular 5-Azacytidine infusions for six consecutive weeks followed by observation in the infusion suite for a minimum of 30 minutes and once weekly 21 mg intraventricular trastuzumab infusions for six consecutive weeks followed by observation for a minimum of 2 hour after each infusion for the first 2 infusions. During this monitoring period, temperature, blood pressure, heart rate, and oxygen saturation will be measured. Patients will also have a neurological examination performed to observe for neurological changes. All patients will undergo an MRI of the brain and total spine with and without gadolinium within 7 days after the final 5-AZA and trastuzumab infusion to determine treatment response and to assess for any signal changes in the brain or spine caused by the infusions and they will have a 30 day and a 90 day follow-up assessment by telephone or in person for assessment of outcome measures and safety

| Treatment | Experimental | Not described Receives: Drug: 5-Azacytidine and trastuzumab infusion |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of patients with new neurological deficits
A new neurological deficit will be defined as new cranial neuropathy, change in level of consciousness, motor weakness, gait change or cerebellar finding (ataxia, dysmetria, dysdiadochokinesis) that is attributed by treating physicians to infusions. New neurological deficits graded as Grade 3 or higher after infusions will be defined as serious adverse events (SAE's)
Measured: 7 days after treatment
Secondary outcomes (2)
Change in disease progression as assessed by magnetic resonance imaging (MRI)
Measured: Baseline(before start of treatment),end of treatment (7 days after treatment)
Change in disease progression as assessed by lumbar CSF cytology
Measured: Baseline(before start of treatment),end of treatment (7 days after treatment)

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing 5-Azacytidine and trastuzumab infusion in people with Fossa Ependymoma, run by The University of Texas Health Science Center, Houston at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with new neurological deficits (time frame: 7 days after treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2025.
