Definitions
- the present application relates to amorphous form of a complex of valsartan and Sacubitril, known as LCZ-696.
- the present application relates to amorphous solid dispersion of a complex of valsartan and Sacubitril, known as LCZ-696.
- US Patent No. 8877938 discloses a crystalline form of supramolecular complex of valsartan and Sacubitril. It is known in the literature as LCZ-696 (Tetrahedron Letters 53, 2012, 275-276).
- the US'938 patent characterizes the crystalline form of LCZ-696 by XRD having peaks at 4.5, 5.5, 5.6, 9.9, 12.8, 15.7, 17.0, 17.1 , 17.2, 18.3, 18.5, 19.8, 21 .5, 21 .7, 23.2, 23.3, 24.9, 25.3, 27.4, 27.9, 28.0 and 30.2 °2 ⁇ . But the US'938 patent does not provide the XRD figure of the said compound.
- Tetrahedron Letters 53, 2012, 275-276 discloses the XRD figure of LCZ-696.
- Amorphous material generally offers interesting properties such as higher dissolution rate and solubility than crystalline forms, typically resulting in improved bioavailability.
- An amorphous form of cefuroxime axetil is a good example for exhibiting higher bioavailability than the crystalline form.
- One aspect of the present application relates to process for preparing amorphous form of LCZ-696 comprising:
- step b) optionally filtering the un-dissolved particles; (c) removing the solvent from the filtrate of step b) by suitable technique;
- Another aspect of the present application relates to amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier.
- Yet another aspect of the present application relates to amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier that can be characterized by a PXRD pattern substantially as illustrated in Figure 2 or Figure 3 or Figure 4 or Figure 5 or Figure 6.
- Still another aspect of the present application relates to a process for preparing amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier or mixture thereof comprising:
- Another aspect of the present application relates to a process for preparation of amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier or mixture thereof comprising:
- Another aspect of the present application relates to a process for preparation of amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier comprising mixing amorphous LCZ-696 with one or more pharmaceutically acceptable carrier.

Description
AMORPHOUS SOLID DISPERSION OF LCZ-696
FIELD OF INVENTION
The present application relates to amorphous form of a complex of valsartan and Sacubitril, known as LCZ-696. The present application relates to amorphous solid dispersion of a complex of valsartan and Sacubitril, known as LCZ-696.
BACKGROUND OF INVENTION
US Patent No. 8877938 discloses a crystalline form of supramolecular complex of valsartan and Sacubitril. It is known in the literature as LCZ-696 (Tetrahedron Letters 53, 2012, 275-276). The US'938 patent characterizes the crystalline form of LCZ-696 by XRD having peaks at 4.5, 5.5, 5.6, 9.9, 12.8, 15.7, 17.0, 17.1 , 17.2, 18.3, 18.5, 19.8, 21 .5, 21 .7, 23.2, 23.3, 24.9, 25.3, 27.4, 27.9, 28.0 and 30.2 °2Θ. But the US'938 patent does not provide the XRD figure of the said compound. Tetrahedron Letters 53, 2012, 275-276 discloses the XRD figure of LCZ-696.
It has been disclosed earlier that the amorphous forms in a number of drugs exhibit different dissolution characteristics and in some cases different bioavailability patterns compared to crystalline forms [Konne T., Chem pharm Bull., 38, 2003(1990)]. Typically, the more crystalline the pharmaceutical agent, the lower is its bioavailability or vice varsa, reducing the degree of crystallinity has a positive effect on bioavailability. Amorphous material generally offers interesting properties such as higher dissolution rate and solubility than crystalline forms, typically resulting in improved bioavailability. An amorphous form of cefuroxime axetil is a good example for exhibiting higher bioavailability than the crystalline form.
Hence, there remains a need for alternate solid forms of LCZ-696 and processes for preparing them.

Any temperature and vacuum conditions can be used as long as there is no increase in the impurity levels of the product due to decomposition.
Suitable techniques which can be used for the distillation include, but not limited to, distillation using a rotary evaporator device such as a rotavapor, spray drying, agitated thin film drying ("ATFD"), and the like. Specifically, techniques providing a rapid solvent removal may be utilized to provide the desired amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier. More specifically, distillation using a rotavapor device such as a rotavapor or a spray drying technique may be used for the isolation of amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier.
The solid may be collected using techniques such as by scraping, or by shaking the container, or other techniques specific to the equipment used. The isolated solid may be optionally further dried to afford amorphous solid dispersion of LCZ-696.
Drying may be suitably carried out using any of an air tray dryer, vacuum tray dryer, fluidized bed dryer, spin flash dryer, flash dryer and the like. The drying may be carried out at atmospheric pressure or above, or under reduced pressures, at temperatures less than about 120°C, less than about 100°C, less than about 80°C, or any other suitable temperatures. The drying may be carried out for any time period required for obtaining a desired product quality, such as from about 30 minutes to about 24 hours, or longer.
The obtained amorphous solid dispersion of LCZ-696 may optionally be subjected to a particle size reduction procedure to produce desired particle sizes and distributions. Milling or micronization may be performed before drying, or after the completion of
drying of the amorphous solid dispersions. Equipment that may be used for particle size reduction include, but not limited to, ball, roller, and hammer mills, jet mills and the like.
Another aspect of the present application relates to a process for preparation of amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier comprising mixing amorphous LCZ-696 with one or more pharmaceutically acceptable carrier. The mixing may be carried out by any known methods in the art. Specifically, the mixing may be carried out by blending.

The amorphous solid dispersion of the present application may be easily formulated into a pharmaceutical composition comprising LCZ-696 along with one or more pharmaceutically acceptable excipients. Pure amorphous form of LCZ-696 is highly hygroscopic in nature and has a tendency to absorb large amounts of moisture even at 30% RH/25 °C, as observed in DVS and humidification studies. It has been seen that pure amorphous form of LCZ-696 absorbs about 8% moisture within 3 hours at 30% RH/25 °C and becomes a sticky material . On increasing the relative humidity of the environment further, pure amorphous form of LCZ-696 becomes deliquescent. Hence, pure amorphous form of LCZ-696 may not be suitable for developing a pharmaceutical composition comprising LCZ-696. On the other hand, it was observed that in amorphous solid dispersion of LCZ-696 of the present application, the pharmaceutically acceptable carrier stabilizes
the amorphous LCZ-696 by acting as a protective barrier. It was observed by DVS and humidification studies that the amorphous solid dispersion of LCZ-696 with one or more pharmaceutically acceptable carrier of the present application is stable up to 60% RH/25 °C. Hence, amorphous solid dispersion of LCZ-696 with silicon dioxide may be easily formulated into a pharmaceutical composition comprising LCZ-696.
