Summary This is a Phase II, multicenter, open-label, single arm, 2-stage study of tazemetostat 800 mg BID (twice daily) and 1600 mg QD (once daily). Subjects will be screened for eligibility within 21 days of the planned date of the first dose of tazemetostat and enrolled into one of 8 cohorts: Cohort using tazemetostat 800 mg BID Cohort 1 (Closed for enrollment): MRT, RTK, ATRT, and selected tumors with rhabdoid features, including small cell carcinoma of the ovary hypercalcemic type [SCCOHT], also known as malignant rhaboid tumor of the ovary [MRTO] Cohort 2 (Closed for enrollment): Relapsed or refractory synovial sarcoma with SS18-SSX rearrangement Cohort 3 (Closed for enrollment): Other INI1 negative tumors or any solid tumor with an EZH2 gain of function (GOF) mutation, including: epithelioid malignant peripheral nerve sheath tumor (EMPNST), extraskeletal myxoid chondrosarcoma (EMC), myoepithelial carcinoma, other INI1-negative malignant tumors with Sponsor approval (e.g., dedifferentiated chordoma) any...

Most tumours that start in the pituitary gland are adenomas which are non cancerous (benign). Some pituitary tumours make extra hormones that can cause symptoms. They are sometimes called neuroendocrine tumours. Very rarely, several members of the same family have a pituitary gland tumour. We know from research that there can be a gene that is abnormal in some of these families. Researchers want to study this and other genes to understand more about how these tumours develop. In this study, they will take blood samples from people who have a pituitary gland tumour, and from other family members. The aim of the study is to identify genes that play a part in the development of pituitary gland tumours. Please note - you won’t get any direct benefit from taking part in this study, nor will it affect any treatment you have. But may it help people in the future.

Brief Summary The overall aim of this project is to improve the outcome of patients diagnosed with ependymoma by improving and harmonising the staging and the standard of care of this patient population and to improve the investigators understanding of the underlying biology thereby informing future treatment. The program will evaluate new strategies for diagnosis (centralized reviews of pathology and imaging) and new therapeutic strategies in order to develop treatment recommendations. Patients will be stratified into different treatment subgroups according to their age, the tumour location and the outcome of the initial surgery. Each subgroup will be studied in a specific randomised study to evaluate the proposed therapeutic strategies. Stratum 1: The aim of the stratum 1 is to evaluate the clinical impact of 16-week chemotherapy regimen with VEC-CDDP following surgical resection and conformal radiotherapy in terms of progression free survival in patients who are > 12 months and <...

The study PNET 5 MB has been designed for children with medulloblastoma of standard risk (according to the risk-group definitions which have been used so far; e.g. in PNET 4). With the advent of biological parameters for stratification into clinical medulloblastoma trials, the ß-catenin status will be the only criterion according to which study patients will be assigned to either treatment arm PNET 5 MB - LR or to PNET 5 MB - SR, respectively. The initial diagnostic assessments (imaging, staging, histology, and tumor biology) required for study entry are the same for both treatment arms.

The PNET 5 study has been designed for children and young people aged from 3 yrs to 22 yrs with standard risk medulloblastoma who have undergone surgery to remove the primary tumour. The presence of biological markers of the WNT medulloblastoma disease subgroup (mutation of the beta¬catenin gene, or presence of the beta¬catenin protein and loss of chromosome 6) and aged < 16 defines the patient as Low Risk biological profile. The presence of the WNT markers and aged 16 and over, or the absence of the WNT markers defines the patient as Standard Risk biological profile. Low risk group patients will receive reduced doses of radiotherapy (compared to previous study PNET 4) to the brain and spine every day for 10 days, together with boost doses to the primary tumour for a further 20 days. Maintenance chemotherapy will consist of 6 cycles of Regimen A alternating with 6 cycles...
