This invention further relates to methods for treating cancer with potent deciparticle compositions.

[0120] Deciparticle compositions can be composed of an amphiphilic compound complexed with auxiliary compounds such as biologically active molecules. For example, an auxiliary compound can be a therapeutic agent.

[0121] Deciparticles (nanoparticles) of this invention can be much smaller, sometimes about 1 / 10ththe size, of conventional “nanoparticles” used for treating cancer. The potency of deciparticles of this invention can advantageously exceed that of conventional “nanoparticle” therapies.

[0122] In further aspects, this invention provides deciparticle forms which are stable in blood and exhibit low hemolytic activity.

[0123] Deciparticles of this invention can be stable and stored for extended periods.

[0124] Deciparticles of this invention create a new regime of size and molecular mass for therapeutics. Deciparticles can be prepared with discrete amphiphilic molecules of this disclosure complexed with active agents.

[0125] As used herein, the term deciparticle can refer to small particles formed from discrete amphiphilic molecules of this disclosure contacted with one or more drug molecules.

[0126] A deciparticle composition of this invention can also be lyophilized to a solid lyophile form. A solid lyophile form made from a deciparticle composition can be reconstituted to form a suspension of deciparticles.

[0127] Because the deciparticle compositions can achieve surprisingly small size particles, typically 1 / 10ththe size of conventional nanoparticles, the deciparticle compositions can provide increased mass transport of drug through blood vessel walls.

[0128] Deciparticles of this invention can be used in a pharmaceutical composition containing a pharmaceutically-acceptable carrier and / or excipients. A pharmaceutical composition can be prepared in a conventional manner.

[0129] Without wishing to be bound by theory, deciparticle size is advantageous because the particles approach the size of biological molecules and begin to behave likeDocket No. 018988-025WO1a molecular drug. Deciparticles can circulate in the body largely undetected by the immune system and penetrate biological barriers, entering cells and even nuclei.Cellular uptake of deciparticles can be inversely size-dependent because of ultrasmall size, where smaller particles have increased uptake. Endocytosis pathways depend on size so that clathrin-mediated pathways dominate for 5-50 nm. Key physicochemical features can be controlled by size. For example, renal filtration, where 2-4 nm PEG-silica or PEG-Au are rapidly cleared in urine.

[0130] This disclosure relates to the discovery that deciparticles provide properties not available to larger particles such as typical liposomes and micelles. Deciparticles are not lost to renal filtration. Deciparticles can have increased cellular uptake and reduced immunogenicity.

[0131] As used herein, trademark protection for the term DECIPARTICLES has been applied for in the U. S. and under the Madrid Agreement has been granted in many countries.Deciparticle compositions and properties

[0216] In some embodiments, deciparticles (nanoparticles) were formed by mixing acetone solutions of an amphiphile compound and a drug compound together to achieve a final concentration of 2 mg / mL for drug and 20 mg / mL for amphiphile, a ratio of 1: 10. The ratio can be varied over a wide range, for example, from 1: 100 (0.01% drug) to 1:1.5 (40% drug). The solvent acetone can be evaporated with vacuum to produce a dry film composed of isolatedDocket No. 018988-025WO1deciparticles. The isolated deciparticles can be reconstituted with 60°C deionized water. The isolated deciparticles can optionally be incubated at 60°C for about 10 minutes before or after the reconstitution step. The absence of free drug molecules can be confirmed by the absence of any white solid precipitate in the film or turbidity in the reconstituted suspension.

[0217] In this method, isolated deciparticles can be prepared so that all of the active drug compound is within the deciparticles. This ensures that measurements of activity or potency relate directly to the deciparticles.

[0218] A pertinent method for making a deciparticle composition of this disclosure can include any or all of the following steps:-mixing one or more therapeutic agents in an organic solvent;-contacting an amphiphilic compound with therapeutic agents in an organic solvent;-mixing or vortexing the organic solvent;-filtering the deciparticle composition in the organic solvent to remove particles or aggregates larger than 15 nm, or 30 nm, or 75 nm, or 100 nm;-removing residual organic solvent and / or agents from the deciparticle composition.

[0219] In some embodiments, deciparticles were formed by the following steps: dissolving one or more amphiphiles in an organic solvent;contacting one or more auxiliary taxane compounds with the one or more amphiphiles in the organic solvent;adding water or buffered water containing a cryoprotective compound slowly to the water-solvent mixture, thereby obtaining a suspension of deciparticles;mixing the water-solvent mixture;filtering the water-solvent mixture, thereby obtaining a sterilized suspension of deciparticles;lyophilizing the water-solvent mixture to obtain a deciparticle composition.

[0220] In further embodiments, compositions of deciparticles may comprise:a suspension of deciparticles in a pharmaceutically-acceptable water-solvent mixture; and a cryoprotective compound added to the water-solvent mixture.

[0221] In some embodiments, deciparticles were formed by the following steps: freezing a suspension of deciparticles; and lyophilizing the frozen composition.

[0223] In some embodiments, isolated deciparticles can be prepared so that all of the auxiliary taxane compounds are within the deciparticles. This ensures that measurements of activity or potency relate directly to the deciparticles.

[0224] A pertinent method for making a deciparticle composition of this disclosure can include any or all of the following steps:

[0225] -mixing one or more auxiliary taxane compounds in an organic solvent;-contacting an amphiphilic compound with auxiliary taxane compounds in an organic solvent; -mixing or vortexing the organic solvent;-filtering the deciparticle composition in the organic solvent to remove impurities, particles or aggregates larger than 15 nm, or 30 nm, or 75 nm, or 100 nm, and optionally to sterilize the composition;-removing residual organic solvent from the deciparticle composition.

[0226] In certain embodiments, clinical lots can be made in a 2-7 day process. An amphiphile such as Compound 111 and one or more active agents such as everolimus or paclitaxel can be dissolved in ethanol. The ingredients can be solubilized into lactose and water for injection to form deciparticles. The process can be conducted under yellow light and utilize amber vials to minimize active agent degradation. The deciparticles product can be filter-sterilized. Fill / finish operations can be done in a temperature-controlled environment with98% filling weight accuracy. The deciparticles everolimus product can be reconstituted to a final concentration of 4 mg / mL for intravenous administration. Upon reconstitution, the product can yield monodisperse deciparticles that meet sterility and particle-size specifications. The product can remain within specifications for at least one month at 5°C storage and for at least 24 hours of in-use stability at 25°C. The process can be scaled to over 10 g, sufficient for Phase 1 clinical supply.Docket No. 018988-025WO1Methods for using deciparticle compositions
