Pharmaceutical compositions comprising a macromolecular pharmaceutical agent in micellar form are disclosed. The micelles are formed from an alkali metal alkyl sulfate, and at least one additional micelle-forming compound as described in the specification. An alkali metal salicylate and a pharmaceutically acceptable edetate are also included in the composition. Micelle size ranges between about 1 and 10 nanometers. Methods for making and using the compositions are also disclosed.

This invention discloses compositions of chloroquine-coupled active agents such as therapeutic antibodies or insulin, including methods for their preparation. The prior art has shown that chloroquines given as free drug in high enough concentration, enhances the release of various agents from cellular endosomes into the cytoplasm. The purpose of these compositions is to provide a controlled amount of chloroquine at the same site where the drug is delivered, thereby reducing the overall dosage needed. The compositions comprise a chloroquine substance coupled to a drug directly or through a variety of pharmaceutical carrier substances. The carrier substances include polysaccharides, synthetic polymers, proteins, micelles and other substances for carrying and releasing the chloroquine compositions in the body for therapeutic effect. The compositions can also include a biocleavable linkage for carrying and releasing the drug for therapeutic or other medical uses. The invention also discloses carrier compositions that are coupled to targeting molecules for targeting the delivery of chloroquine substances and antibody or insulin to their site of action.

The present invention relates generally to novel, selectable hybrid polypeptides useful as agents for the treatment and prevention of metabolic diseases and disorders which can be alleviated by control plasma glucose levels, insulin levels, and/or insulin secretion, such as diabetes and diabetes-related conditions. Such conditions and disorders include, but are not limited to, hypertension, dyslipidemia, cardiovascular disease, eating disorders, insulin-resistance, obesity, and diabetes mellitus of any kind, including type 1, type 2, and gestational diabetes.

Expression systems are disclosed for the direct expression of peptide products into the culture media where genetically engineered host cells are grown. High yield was achieved with novel vectors, a special selection of hosts, and/or fermentation processes which include careful control of cell growth rate, and use of an inducer during growth phase. Special vectors are provided which include control regions having multiple promoters linked operably with coding regions encoding a signal peptide upstream from a coding region encoding the peptide of interest. Multiple transcription cassettes are also used to increase yield. The production of amidated peptides using the expression systems is also disclosed.

Peptides having at least 2 amino acids and no more than 15 amino acids are provided. The peptides comprise amino acid sequence X-Y or Y-X, wherein X is an aromatic amino acid and Y is any amino acid other than glycine. Also provided are pharmaceutical compositions and kits including such peptides as well as methods using same for diagnosing and treating amyloid associated diseases.

The present invention relates to compositions and methods for transdermal drug delivery comprising formulating a phosphatidylcholine carrier composition containing the drug and applying the composition to the skin.

Pharmaceutical formulations and methods are provided for the sustained delivery of a pharmaceutical agent to a patient by injection, by oral administration or by topical administration. The injectable formulation includes porous microparticles which comprise a pharmaceutical agent and a matrix material, wherein upon injection of the formulation a therapeutically or prophylactically effective amount of the pharmaceutical agent is released from the microparticles for at least 24 hours. The oral formulation includes porous microparticles which comprise a pharmaceutical agent and a matrix material, wherein a therapeutically or prophylactically effective amount of the pharmaceutical agent is released from the microparticles for at least 2 hours following oral administration. The topical formulation includes porous microparticles which comprise a pharmaceutical agent and a matrix material, wherein a therapeutically or prophylactically effective amount of the pharmaceutical agent is released from the microparticles for at least 2 hours following topical administration.

Methods are provided for purifying peptides and proteins by incorporating the peptide or protein into a diketopiperazine or competitive complexing agent to facilitate removal of one or more impurities from the peptide or protein. Formulations and methods also are provided for the improved transport of active agents across biological membranes, resulting for example in a rapid increase in blood agent concentration. The formulations include microparticles formed of (i) the active agent, which may be charged or neutral, and (ii) a transport enhancer that masks the charge of the agent and/or that forms hydrogen bonds with the target biological membrane in order to facilitate transport. In one embodiment insulin is administered via the pulmonary delivery of microparticles comprising fumaryl diketopiperazine and insulin in its biologically active form. This method of delivering insulin results in a rapid increase in blood insulin concentration that is comparable to the increase resulting from intravenous delivery.

This invention relates to modified nucleic acid compositions encoding cell-penetrating polypeptides to provoke an innate immune response in a cell and methods of delivering protein-binding partners to target cells.

The present invention is directed to methods and devices for delivering an active agent formulation to the lung of a human patient. The active agent formulation may be in dry powder form, it may be nebulized, or it may be in admixture with a propellant. The active agent formulation is delivered to a patient at an inspiratory flow rate of less than 17 liters per minute. The bioavailability of the active agent was found to increase at these flow rates when compared to inspiratory flow rates of 17 liters per minute or more.

To address the issue of degradation by enzymatic reactions to proteins and peptides, polyethylene glycol (PEGylation) of the proteins and peptides has been established. PEGylated proteins and peptides have increased plasma half-lives and reduced immunogenicity. To further improve and extend the plasma half-life of desired protein or peptide therapeutics, a novel branched molecule of PEG possessing three PEGs with a single point of attachment is designed in this invention disclosure.

Pharmaceutical compositions that include a drug and/or drug-oligomer conjugate, a fatty acid component and a bile salt component, or a bile salt component without a fatty acid component are described. The drug can be covalently coupled to an oligomeric moiety. The fatty acid component and the bile salt component, when together, can be present in a weight-to-weight ratio of between 1:15 and 15:1 or any value between. Methods of treating diseases in a subject in need of such treatment using the pharmaceutical compositions of this invention are also provided, as well as methods of providing such pharmaceutical compositions.

A method for treating a patient to promote bone growth, comprising: administering to the patient a therapeutic amount of a bone remodeling agent effective to stimulate bone growth, and a dietary supplement comprising calcium and phosphorus, in a therapeutic amount effective to prevent a deficiency in the amount of calcium or phosphorus available for bone growth.

The invention is directed to methods of promoting neurogenesis by contacting neuronal tissue with neurogenesis modulating agents. Novel methods for treating neurological disorders using neurogenesis modulating agents are disclosed.

Solid pharmaceutical compositions suitable for the oral delivery of pharmacologically active agents, e.g. peptides, comprising a therapeutically-effective amount of a pharmacologically active agent; a crospovidone or povidone; and a delivery agent for said pharmacologically active agent are disclosed. The compositions provide excellent oral bioavailability of pharmacologically active agents, particularly calcitonin.
