    Phase I Dose Escalation and Expansion Study of Tazemetostat in Combination With Topotecan and Pembrolizumab in Recurrent Small Cell Lung Cancer

    Summary: This phase I trial tests the safety, side effects, and best dose of tazemetostat in combination with topotecan and pembrolizumab in treating patients with small cell lung cancer that has come back after a period of improvement (recurrent). Tazemetostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as topotecan, work in different...

    Symphony-1: A Phase 1b/3 Double-Blind, Randomized, Active-Controlled, 3-Stage, Biomarker Adaptive Study Of Tazemetostat Or Placebo In Combination With Lenalidomide Plus Rituximab In Subjects With Relapsed/Refractory Follicular Lymphoma

    Summary: The participants of this study would have relapsed/refractory follicular lymphoma. Follicular lymphoma is a type of blood cancer. It is referred to as 'relapsed' when the disease has come back after a period of improvement after that follows a treatment regimen and 'refractory' when treatment no longer works. Stage 1 of this trial will study the safety and the level that adverse effects of each of...

    A Phase I, Open-label Multi-dose Pharmacokinetic and Safety Study of Oral Tazemetostat in Subjects With Moderate and Severe Hepatic Impairment With Advanced Malignancies

    Summary: This main aim of this trial will be to study the blood levels (known as pharmacokinetics) of the study drug tazemetostat. The pharmacokinetics of the study drug in participants with advanced solid tumors and moderate or severe hepatic (liver) impairment will be compared with participants with advanced malignancies and normal hepatic function. An advanced malignancy is a cancer that has recurred (c...

    Phase Ib/II Study of Safety and Efficacy of EZH2 Inhibitor, Tulmimetostat, and PD-1 Blockade for Treatment of Advanced Non-small Cell Lung Cancer

    Summary: This is an open label, single arm, phase Ib/II clinical trial of checkpoint blockade, pembrolizumab and EZH2 inhibitor, tulmimetostat combination therapy for patients with advanced non-small cell lung cancer who have progressed from front or second-line treatment. Patients will be enrolled at multiple Veterans Affairs Medical Centers.

    Phase II, Single Arm, Open Label, Study of the Combination of Pembrolizumab and Tazemetostat to Overcome Immune Tolerance Following ASCT or CAR T-Cell Therapy in Patients With Aggressive B-Cell Non-Hodgkin's Lymphoma

    Summary: This phase II trial tests how well pembrolizumab and tazemetostat work to treat patients who have received autologous stem cell transplantation (ASCT) or chimeric antigen receptor (CAR) T cell therapy for aggressive non hodgkins lymphoma. A monoclonal antibody, such as pembrolizumab, is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an...

    A Phase 1b Study of Tazemetostat in Combination With Zanubrutinib and Anti-CD20 Monoclonal Antibody in Relapsed or Refractory Indolent B-cell Non-Hodgkin Lymphomas (TARZAN Trial)

    Summary: The purpose of this clinical trial is to learn if the study drug Tazemetostat combined with Zanubrutinib and anti-CD20 monoclonal antibody is safe and effective in treating patients with relapsed or refractory indolent B-cell non-Hodgkin lymphoma.

    Phase 1/Expansion Study of Tazemetostat Plus Belinostat for the Treatment of Relapsed or Refractory Lymphoma

    Summary: This phase I trial tests the safety, side effects, and best dose of combination therapy with tazemetostat and belinostat in treating patients with lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Tazemetostat is in a class of medications called EZH2 inhibitors. The EZH2 gene provides instructions for making a type of enzyme ca...

    Randomized Phase II Study of the Addition of Targeted Therapeutic Agents to Tafasitamab-Based Therapy in Non-Transplant-Eligible Patients With Relapsed/Refractory Large B-Cell Lymphoma

    Summary: This phase 2 trial studies the side effects and best dose of tazemetostat and zanubrutinib in combination with tafasitamab and lenalidomide, and to see how well these combinations work in treating patients with large B-cell lymphoma that returned or did not respond to earlier treatment. Tazemetostat is in a class of medications called EZH2 inhibitors. It helps to stop the spread of cancer cells. Z...

    TAZNI: A Phase I/II Combination Trial of Tazemetostat With Nivolumab and Ipilimumab for Children With INI1-Negative or SMARCA4-Deficient Tumors

    Summary: This research study involves a combination of three drugs given together as a possible treatment for malignant rhabdoid tumor, atypical teratoid rhabdoid tumor, epithelioid sarcoma, chordoma or other tumors that are deficient in one of two possible proteins, either INI-1 (SMARCB1) or SMARCA4. The names of the study drugs involved in this study are: * Tazemetostat (TAZVERIK) * Nivolumab (OPDIVO) * ...

    Phase I Study to Evaluate Safety and Tolerability of Tazemetostat in Relapsed/Refractory Peripheral T-cell Lymphoma

    Summary: Tazemetostat is an oral EZH2 inhibitor which has been FDA approved for adult patients with relapsed or refractory (R/R) follicular lymphoma (FL) whose tumors are positive for an EZH2 mutation as detected by an FDA-approved test and who have received at least 2 prior systemic therapies, and for adult patients with R/R FL who have no satisfactory alternative treatment option. We propose a study to e...

    A Feasibility Trial of Tazemetostat Plus CAR T Cell Therapy in B-cell Lymphomas

    Summary: This is a clinical trial to evaluate the feasibility and safety of giving tazemetostat followed by standard of care CAR T cell infusion in previously treated diffuse large b-cell lymphoma (DLBCL), follicular lymphoma (FL), and mantle cell lymphoma (MCL). The investigators hypothesis is that this combination has the potential to significantly improve the ability of CART cells to recognize and kill ...
