Study Summary

This trial is studying how well tazemetostat works in treating patients with brain tumors, solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have come back or do not respond to treatment and have EZH2, SMARCB1, or SMARCA4 gene mutations.

Who is the study for?
This trial is for patients with relapsed or refractory advanced solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with specific gene mutations (EZH2, SMARCB1, SMARCA4). Participants must have measurable disease and recovered from previous cancer therapies. They need adequate blood counts and organ function and can't have had prior EZH2 inhibitor treatment.Check my eligibility
What is being tested?
The trial tests Tazemetostat's effectiveness in stopping tumor growth by blocking a protein called EZH2. It targets patients whose cancers haven't responded to other treatments and who carry certain genetic mutations that may be affected by this drug.See study design
What are the potential side effects?
Potential side effects of Tazemetostat include fatigue, nausea, vomiting, constipation, decreased appetite and weight loss. There might also be changes in liver enzymes or blood cell counts leading to an increased risk of infections.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Who is eligible to sign up for this clinical trial?

"This research project seeks to enrol 20 children aged between 12 months and 21 years who have been diagnosed with rhabdoid tumour. In addition, the participants must satisfy numerous conditions: bone marrow infiltration except that detected by MIBG scan for neuroblastoma; malignant fluid accumulations (e.g., ascites or pleural effusions); inclusion in APEC1621SC and a designated therapy plan based on actionable mutations; lesions only identified through nuclear medicine studies aside from those concerning neuroblastoma; heightened tumor markers found within plasma samples or cerebrospinal fluid (CSF); previously irradiated areas not showing evident"

Answered by AI

Does the research protocol include individuals aged fifty and older?

"Participants between the ages of 12 months and 21 years are welcome to partake in this study."

Answered by AI

Can you provide an overview of the research that has been conducted with Tazemetostat?

"At the moment, 20 trials for Tazemetostat are in progress with two of them being classified as Phase 3. Marshfield, Wisconsin is one of 1302 locations where research on this medication is conducted."

Answered by AI

Is this an original or unprecedented trial?

"Research on Tazemetostat began in 2015, spearheaded by Epizyme Inc. with a sample size of 250 participants. This initial study allowed for the drug to progress through Phase 2 and gain approval from respective medical boards. Currently, there are 20 live trials located across 21 countries and 533 cities worldwide researching this medication's efficacy."

Answered by AI

What side effects have been associated with the use of Tazemetostat?

"The safety of Tazemetostat was evaluated and rated a 2, as this is currently in Phase 2 clinical trials. This suggests that there is evidence to support the drug's safety but no data validating its efficacy yet."

Answered by AI

How many participants are the researchers accepting into this trial?

"Unfortunately, no participants are currently being sought for this study. The trial was first posted on July 24th 2017 and last updated November 16th 2022. For those searching other trials, there is a total of 5678 clinical studies recruiting patients afflicted with rhabdoid tumor and 20 investigations seeking enrollees to be administered Tazemetostat."

Answered by AI

At how many outposts is this investigation obtainable?

"This clinical trial is occurring in 100 different medical facilities, including the University of Wisconsin Hospital and Clinics in Madison, Ascension Saint Vincent Indianapolis Hospital in Indianapolis, and Children's Hospital and Medical Center of Omaha in Omaha."

Answered by AI

Is this experiment actively seeking participants at the moment?

"This trial has now closed its recruitment window, having first been posted on July 24th 2017 and most recently updated November 16th 2022. However, if you are seeking another clinical study to join there are 5678 studies looking for rhabdoid tumour patients and a further 20 trials recruiting participants who will be treated with Tazemetostat."
