About this study
Official title: Memantine to Preserve Memory and Neurocognition Following Craniospinal Irradiation- A Randomised Controlled Trial (MEMENTO)
The goal of this clinical trial is to evaluate the role of memantine in preservation of memory and neurocognition in patients undergoing craniospinal irradiation. Participants will be randomised into two arms and the interventional arm will receive memantine along with the standard treatment. Researchers will compare the neurocognitive tests of participants in both the arms to see if memantine leads to significant preservation of memory and cognition post radiation therapy.
Read the detailed description
Craniospinal irradiation (CSI) involving radiation (RT) of brain and spine, along with tumor-bed boost with or without chemotherapy, is the current standard treatment for medulloblastoma and other primitive embryonal tumors of the central nervous system (CNS). The delayed side effects following CSI include memory loss, hearing and balance difficulties, hormonal imbalance, and secondary cancers. Decline in memory severely affects the quality of life in long term survivors of these diseases. Hence, various strategies are being tried to prevent it. Memantine has been proven to effectively prevent the memory decline induced by RT. It is FDA-approved for Alzheimer's disease and is widely used in the children for several developmental disorders. With this study, we are trying to investigate the role of memantine in patients receiving CSI to prevent memory decline.
After screening for the study, eligible patients will be randomly allocated (by computerised system) to one of the two arms that are described as follows. Patients in the experimental arm (memantine) will be started on memantine, starting dose of the same will be 5mg once daily at bedtime for 1 week, followed by 5mg twice daily for 1 week, and finally increased to the full dose of 10 mg twice daily for 6 months. Patients will continue on radiation and chemotherapy (when indicated) as per schedule. All patients in the study will undergo neurocognitive evaluation, the time points for which will be pre-radiation (baseline), 6 months post-RT, 1-year post-RT, and annually after that for 5 years from radiation. Following completion of RT or treatment, standard follow-up protocols will include a clinical examination 3 monthly for the first 2 years, followed by 6 monthly visits till 5 years post-RT. No additional risk is expected from the current study other than the common side effects of the standard treatment. Based on the results from the study, if primary endpoints are achieved, it will establish the role of memantine in preventing memory decline from CSI, which can be used as a standard treatment measure to help patients in the future.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Memantine Oral Tablet in people with Neurocognitive Dysfunction, run by Tata Memorial Centre at 1 site in India.
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 4 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 9 Apr 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 India. 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?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Tejpal Gupta, MD (02224177000 ext. 6015, drtejpalgupta@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cognitive-deterioration-free survival at 2 years (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06275035, which also lists 3 linked publications.
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 9 Apr 2025.
