Definitions
- the present invention relates to crystalline forms of [1,1 ’-Biphenyl] -3 -carboxamide, N- [(l,2-dihydro-4,6-dimethyl-2-oxo-3-pyridinyl)methyl]-5-[ethyl(tetrahydro-2H-pyran-4- yl)amino]-4-methyl-4’-(4-morpholinylmethyl)-, hydrobromide and process for its preparation thereof.
- Tazemetostat hydrobromide is chemically known as [1,1 ’-Biphenyl] -3-carboxamide, N- [(l,2-dihydro-4,6-dimethyl-2-oxo-3-pyridinyl)methyl]-5-[ethyl(tetrahydro-2H-pyran-4-yl) amino]-4-methyl-4’-(4-morpholinylmethyl)-, hydrobromide (1:1) represented by the following structural formula.
- Tazemetostat is a selective, orally bioavailable, small molecule inhibitor of the enhancer of zeste homolog 2 (EZH2), a histone methyltransferase.
- EZH2 is the catalytic subunit of the polycomb repressive complex 2, catalyzing mono, di-, and trimethylation of lysine 27 of histone H3, which leads to repression (transcriptional regulation) of certain important gene sets such as tumor suppressors, differentiation markers, cell cycle regulators, and apoptotic machinery.
- Tazemetostat is approved in US as TAZVERIK tablet for oral administration for the treatment of adults and pediatric patients aged 16 years and older with metastatic or locally advanced epithelioid sarcoma not eligible for complete resection.
- Tazemetostat is disclosed in US8410088 B2 and this patent also discloses process for the preparation of Tazemetostat trihydrochloride.

- Polymorphism is the occurrence of different crystalline forms of a single compound and it is a property of some compounds and complexes. Thus, polymorphs are distinct solids sharing the same molecular formula, yet each polymorph may have distinct physical properties. Therefore, a single compound may give rise to a variety of polymorphic forms where each form has different and distinct physical properties, such as different solubility profiles, different melting point temperatures and/or different x-ray diffraction peaks. Since the solubility of each polymorph may vary, identifying the existence of pharmaceutical polymorphs is essential for providing pharmaceuticals with predicable solubility profiles. It is desirable to investigate all solid state forms of a drug, including all polymorphic forms, and to determine the stability, dissolution and flow properties of each polymorphic form.
- Polymorphic forms of a compound can be distinguished in a laboratory by X-ray diffraction spectroscopy and by other methods such as, infrared spectrometry. Additionally, polymorphic forms of the same drug substance or active pharmaceutical ingredient, can be administered by itself or formulated as a drug product (also known as the final or finished dosage form), and are well known in the pharmaceutical art to affect, for example, the solubility, stability, flowability, tractability and compressibility of drug substances.
