MannKind Corporation, based in Valencia, California, is a biopharmaceutical company focusing on the discovery, development, and commercialization of therapeutic products for diseases such as diabetes and cancer. The company, while founded in February 1991, took its present form in 2003 as a merger of three companies owned by Alfred E. Mann, named after its founder. Mann has invested approximately $900 million in his company. One of the former companies, Pharmaceutical Discovery, was purchased in 2001 from Solomon Steiner; with that purchase MannKind acquired the Technosphere molecule and Medtone Inhaler, upon which was developed its lead product, Afrezza , which was under review by the U.S. Food and Drug Administration . Previously led by Mann in his position as chief executive officer, Mannkind's board announced the appointment of Hakan Edstrom as CEO on January 12, 2015 as Mann has transitioned to the role of executive chairman.

Compositions and methods have been developed for transporting compounds across membranes with little or no toxicity and, when targeted through the appropriate routes of administration (i.e., lung, gastrointestinal (GI) tract), little or no immune stimulation. The compositions can mediate cellular delivery of compounds that would otherwise not enter cells and enhance the intracellular delivery of compounds that would otherwise enter cells inefficiently. The methods are carried out by contacting a proximal face of a lipid bilayer or membrane (e.g. the surface of an intact cell) with a complex containing a compound (e.g., a therapeutic agent) and a diketopiperazine (DKP). DKP and the compound are non-covalently associated with each other or covalently bound to each other.


Methods are provided for promoting the adsorption of an active agent to microparticles by modifying the structural properties of the active agent in order to facilitate favorable association to the microparticle.


Methods are provided for drying a particle. Specifically, there is provided a spray-dried diketopiperazine-insulin particle formulation having improved aerodynamic performance and in which the active agent is more stabile and efficiently delivered as compared to that of the lyophilized diketopiperazine-insulin formulation. The dry powders have utility as pharmaceutical formulations for pulmonary delivery.


The present disclosure relates to an improved device and methods for adapting to a laser diffraction apparatus used for measuring particle size distribution and density of the plume of a powder composition emitted from a dry powder inhaler.

Compounds which directly inhibit IRE-1 activity in vitro, prodrugs, and pharmaceutically acceptable salts thereof. Such compounds and prodrugs are useful for treating diseases associated with the unfolded protein response or with regulated IRE1-dependent decay (RIDD) and can be used as single agents or in combination therapies.
