[0048] Pharmaceutical preparations for oral administration can be formulated with appropriate and suitable dosages using pharmaceutically acceptable carriers well known in the art. Such carriers enable the drug to be formulated into unit doses of tablets, gel tablets, pills, powders, dragees, capsules, liquids, lozenges, gels, syrups, slurries, suspensions, etc. suitable for patient intake. Oral pharmaceutical preparations can be formulated into solid excipients, optionally grinding the resulting mixture, and if necessary, processing the granular mixture after adding a suitable additional compound to obtain tablets or dragee cores. Suitable solid excipients are carbohydrate fillers or protein fillers, including, for example, sugars, including lactose, sucrose, mannitol or sorbitol; starch from corn, wheat, rice, potatoes or other plants; cellulose, such as methylcellulose, hydroxypropyl methylcellulose or sodium carboxymethylcellulose; and gums, including gum arabic and tragacanth; and proteins, such as gelatin and collagen. Disintegrants or solubilizers such as cross-linked polyvinyl pyrrolidone, agar, alginic acid or its salts (such as sodium alginate) can be added.

[0049] The sugar-coated pill core has a suitable coating, such as a concentrated sugar solution, which can also contain gum arabic, talcum, polyvinyl pyrrolidone, carbomer gel, polyethylene glycol and / or titanium dioxide, lacquer solution and a suitable organic solvent or solvent mixture. Dye or pigment can be added to tablets or sugar-coated pill coatings for identifying products or characterizing the amount (i.e. dosage) of active compounds. The pharmaceutical preparations provided herein and the pharmaceutical preparations for implementing the methods provided herein can also be used orally, for example, using push-in capsules made of gelatin and soft sealed capsules made of gelatin and coatings such as glycerol or sorbitol. Push-in capsules can contain an activating agent mixed with a filler or adhesive (such as lactose or starch), a lubricant (such as talcum or magnesium stearate) and an optional stabilizer. In soft capsules, these activating agents can be dissolved or suspended in a suitable liquid, such as fatty oils, liquid paraffin or liquid polyethylene glycol containing or not containing a stabilizer.

[0050] The aqueous suspension may contain an active agent as provided herein, such as a human antibody or humanized antibody that is capable of specifically binding to the human FcγRI (CD64) receptor at its Fc region but does not bind or substantially binds to other human FcγRs and is capable of specifically binding to the αvβ3 (avb3) polypeptide expressed on the surface of cells (optionally including immune cells), in admixture with excipients suitable for preparing aqueous suspensions. Such excipients include suspending agents (such as sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcellulose, sodium alginate, polyvinylpyrrolidone, tragacanth and gum arabic) and dispersants or wetting agents, such as naturally occurring phosphatides (such as lecithin), condensation products of alkylene oxide and fatty acids (such as polyoxyethylene stearate), condensation products of ethylene oxide and long-chain fatty alcohols (such as heptadecaethyleneoxy hexadecyl alcohol), condensation products of ethylene oxide and partial esters derived from fatty acids and hexitol (such as polyoxyethylene sorbitol monooleate) or condensation products of ethylene oxide and partial esters derived from fatty acids and hexitol anhydrides (such as polyoxyethylene sorbitan monooleate). The aqueous suspension can also contain one or more preservatives (such as ethyl p-hydroxybenzoate or n-propyl p-hydroxybenzoate), one or more coloring agents, one or more flavors and one or more sweeteners (such as sucrose, aspartame or saccharin). The osmotic pressure of the preparation can be adjusted.

[0051] Oil-based drugs are particularly suitable for administering hydrophobic active agents (e.g., anti-αvβ3 (avb3) antibodies) for implementing the methods provided herein. Oil-based suspensions can be prepared by suspending the active agent in a vegetable oil (such as peanut oil, olive oil, sesame oil, or coconut oil) or a mineral oil (such as liquid paraffin) or a mixture of these oils. See, for example, U.S. Pat. No. 5,716,928 (see also U.S. Pat. No. 5,858,401), which describes the use of essential oils or essential oil components to improve the bioavailability of orally administered hydrophobic drug compounds and reduce the variability of the compound between and within individuals. The oil suspension may contain a thickener, such as beeswax, hard paraffin, or cetyl alcohol. Sweeteners may be added to provide a palatable oral preparation, such as glycerol, sorbitol, or sucrose. These preparations may be preserved by the addition of antioxidants (such as ascorbic acid). As an example of injectable oily solvents, see Minto (1997), "Journal of Pharmacology and Experimental Therapeutics" (J.Pharmacol.Exp.Ther.), Vol. 281, pp. 93-102. The pharmaceutical preparations provided herein can also be in the form of oil-in-water emulsions. The oil phase can be a vegetable oil or mineral oil as described above or a mixture of these oils. Suitable emulsifiers include naturally occurring gums (such as gum arabic and tragacanth), naturally occurring phospholipids (such as soybean lecithin), esters or partial esters derived from fatty acids and hexitol anhydrides (such as sorbitan monooleate) and condensation products of these partial esters with ethylene oxide (such as polyoxyethylene sorbitan monooleate). The emulsifier can also contain sweeteners and flavors, such as sweeteners and flavors in syrup and elixir preparations. Such preparations can also contain a demulcent, a preservative or a coloring agent.

[0052] In practicing the embodiments provided herein, the drug compound can also be administered by intranasal, intravenous (IV), intramuscular, sublingual, intraocular and intravaginal routes, including suppositories, insufflations, powders and aerosol formulations (for steroid inhaler examples, see Rohatagi (1995), Journal of Clinical Pharmacology (J. Clin. Pharmacol.), Vol. 35, pp. 1187-1193; Tjwa (1995), Ann. Allergy Asthma Immunol., Vol. 75, pp. 107-111). Suppository formulations can be prepared by mixing the drug with a suitable non-irritating excipient, which is solid at room temperature but liquid at body temperature and will therefore melt in the body to release the drug. Such materials are cocoa butter and polyethylene glycol.

[0053] In practicing the embodiments provided herein, pharmaceutical compounds formulated as applicator sticks, solutions, suspensions, emulsions, gels, creams, ointments, pastes, jellies, paints, powders, and aerosols can be delivered transdermally via a topical route.

[0054] In the implementation of the embodiments provided herein, the drug compound can also be delivered as a microsphere to slowly release in vivo. For example, slow subcutaneous release microspheres can be administered by intradermal injection; see Rao (1995), "Journal of Biomaterials Science: Polymer Edition" (J.Biomater Sci.Polym.Ed.), Vol. 7, pp. 623-645; as a biodegradable and injectable gel formulation, see, for example, Gao (1995), "Pharmaceutical Research" (Pharm.Res.) Vol. 12, pp. 857-863, 1995; or as a microsphere for oral administration, see, for example, Eyles (1997), "Journal of Pharmacy and Pharmacology" (J.Pharm.Pharmacol.), Vol. 49, pp. 669-674.

[0055] In the implementation of the embodiments provided herein, the drug compound can be administered parenterally, such as by intravenous (IV) administration or by administration into a body cavity or organ lumen. These preparations can include an active agent solution dissolved in a pharmaceutically acceptable carrier. Acceptable solvents and solvents that can be used are water and Ringer's solution (a kind of isotonic sodium chloride). In addition, sterile fixed oils can be used as solvents or suspension media. For this reason, any mild fixed oil can be used, including synthetic monoglycerides or diglycerides. In addition, fatty acids such as oleic acid can also be used to prepare injectable preparations. These solutions are sterile and generally do not contain undesirable substances. These preparations can be sterilized by conventional, well-known sterilization techniques. These preparations can contain pharmaceutically acceptable auxiliary substances required for close physiological conditions, such as pH regulators and pH buffers and toxicity regulators, such as sodium acetate, sodium chloride, potassium chloride, calcium chloride, sodium lactate, etc. The concentration of the active agent in these preparations can vary widely, and will be mainly based on fluid volume, viscosity, body weight, etc., according to the selected specific mode of administration and the needs of the patient. For IV administration, the preparation can be a sterile injectable preparation, such as a sterile injectable aqueous or oily suspension. The suspension can be prepared using those suitable dispersants or wetting agents and suspending agents. The sterile injectable preparation can also be a suspension in a non-toxic parenteral acceptable diluent or solvent, such as 1,3-butanediol solution. Administration can be by push injection or continuous infusion (e.g., introduced into a blood vessel substantially uninterruptedly over a specified period of time).

[0056] The pharmaceutical compounds and preparations provided herein and the pharmaceutical compounds and preparations for implementing the methods provided herein can be lyophilized. Also provided are stable lyophilized preparations including compositions provided herein, which can be prepared by lyophilizing a solution including a medicine provided herein and a filler (e.g., mannitol, trehalose, raffinose and sucrose or a mixture thereof). A method for preparing a stable lyophilized preparation can include lyophilizing a solution of a sodium citrate buffer solution of about 2.5 mg / mL protein, about 15 mg / mL sucrose, about 19 mg / mL NaCl and pH greater than 5.5 but less than 6.5. See, for example, U.S. Patent Application No. 20040028670.

[0057] Compositions and preparations provided herein and compositions and preparations for implementing the methods provided herein can be delivered by using liposomes. By using liposomes, especially when the liposome surface carries a ligand specific to the target cell or preferentially targets a specific organ, people can focus on delivering the active agent to the target cell in the body. See, for example, U.S. Patent No. 6,063,400; U.S. Patent No. 6,007,839; Al-Muhammed (1996), Journal of Microencapsulation (J. Microencapsul.), Vol. 13, pp. 293-306; Chonn (1995), Contemporary Biotechnology Review (Curr. Opin. Biotechnol.), Vol. 6, pp. 698-708; Ostro (1989), Am. J. Hosp. Pharm., Vol. 46, pp. 1576-1587.

[0058] The formulations provided herein and the formulations for implementing the methods provided herein can be used for preventive treatment administration and / or therapeutic treatment administration. In therapeutic applications, the composition is administered to a subject already suffering from a condition, infection or disease in an amount sufficient to cure, alleviate or partially prevent the clinical manifestations of the condition, infection or disease and its complications ("therapeutically effective amount"). For example, in alternative embodiments, the pharmaceutical compositions provided herein are administered in an amount sufficient to treat or improve advanced cancers (such as drug-resistant cancers expressing αvβ3 polypeptides on their cell surfaces) or to kill cancer stem cells (CSCs) expressing αvβ3 polypeptides on their cell surfaces. The amount of the pharmaceutical composition sufficient to achieve this is defined as a "therapeutically effective dose". The dosage regimen and amount (i.e., "dosage regimen") effective for this use will depend on a variety of factors, including the stage of the disease or condition, the severity of the disease or condition, the general health status of the patient, the patient's physical condition, age, etc. When calculating the patient's dosage regimen, the mode of administration is also taken into account.

[0059] The dosage regimen also takes into account pharmacokinetic parameters well known in the art, i.e., absorption rate, bioavailability, metabolism rate, clearance rate, etc. of the active agent (see, e.g., Hidalgo-Aragones (1996), J. Steroid Biochemistry and Molecular Biology). (1996), Pharmazie, Vol. 51, pp. 337-341; Fotherby (1996), Contraception, Vol. 54, pp. 59-69; Johnson (1995), J. Pharm. Sci., Vol. 84, pp. 1144-1146; Rohatagi (1995), Pharmazie, Vol. 50, pp. 610-613; Brophy (1983), Eur. J. Clin. Pharmacol., Vol. 24, pp. 103-108; the latest by Remington, supra). The prior art allows the clinician to determine the dosage regimen for each individual patient, active agent, and disease or condition being treated. The guidance provided for similar compositions used as pharmaceuticals can be used to determine whether the dosing regimen (ie, dosage schedule and dosage level) for practicing the methods provided herein is correct and appropriate.

[0060] According to the dosage and frequency required and tolerated by the patient, single or multiple administrations of the preparation can be given. The preparation should provide a sufficient amount of active agent to effectively treat, prevent or improve the condition, disease or symptom as described herein. For example, an exemplary pharmaceutical preparation for oral administration of a composition provided herein or a composition for implementing the method provided herein can be administered at a daily dose of about 0.1 μg to 0.5 μg, to about 20 μg, about 50 μg, about 100 μg or about 1000 μg or more μg per kg body weight per day. In an alternative embodiment, the dosage used is about 1 mg to about 4 mg per kg body weight per day per patient. Compared with oral administration, a lower dose can be used to enter the bloodstream, enter the body cavity or enter the lumen of an organ. Substantially higher doses can be used in topical or oral administration or by powder, spray or inhalation administration.
