This phase 1b/2 trial studies how safely the EZH2 inhibitor tazemetostat works with other therapies in various hematological malignancies. Tazemetostat has been found to be a safe and effective drug that works in patients with relapsed refractory (R/R) follicular lymphoma. Giving tazemetostat in combination with other treatments may work better in treating patients with hematological malignancies and may improve disease response and durability of response.
This trial will study how safely the tazemetostat works with other therapies in various hematological malignancies. Hematologic malignancies are cancers that most often begin in the bone marrow or lymph nodes where blood precursors are produced.~They are often called blood cancers and fall into three categories: leukemia, lymphoma and myeloma.~Tazemetostat has been found to be a safe and effective drug that works in patients with follicular lymphoma where the disease has come back after treatment (known as relapsed) and when other treatment no longer works (known as refractory).~Combining tazemetostat with other treatments may work better in treating patients with hematological malignancies and may improve disease response and durability of response.
