This invention further relates to methods for treating cancer with potent deciparticle compositions.
[0109] Deciparticle (nanoparticle) 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.
[0110] Deciparticles 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.
[0111] In further aspects, this invention provides deciparticle forms which are stable in blood and exhibit low hemolytic activity.
[0112] In some embodiments, a deciparticle composition of this invention may be used in a method for treating cancer, for immunosuppression in transplantation, or for severe rheumatoid arthritis, or for disorders involving inflammation in a subject in need.
[0113] Deciparticles of this invention can be stable and stored for extended periods.
[0114] 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.
[0115] 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.Docket No. 018988-020W01
[0116] A deciparticle (nanoparticle) 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.
[0117] 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.
[0118] 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.
[0119] Without wishing to be bound by theory, deciparticle size is advantageous because the particles approach the size of biological molecules and begin to behave like a 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.
[0120] 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.
[0121] 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
