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, who has invested approximately $900 million in the firm. 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 (inhalable insulin).  Mann was chief executive officeruntil January 12, 2015 when Hakan Edstrom became ceo and Mann transitioned to executive chairman.
MannKind's corporate headquarters are in Valencia, California. The Afrezza manufacturing facility is in Danbury, Connecticut.
Products and product candidates
Afrezza is an ultra-rapid-acting insulin peaking 12 to 15 minutes following inhalation. The FDA approved Afrezza on June 27, 2014 with a 13-1 vote for type 1 diabetes and 14-0 vote for type 2 diabetes.
On August 11, 2014 MannKind entered into an exclusive global licensing agreement with Sanofi for Afrezza sales. Under the agreement, MannKind received $150 million cash from Sanofi, in exchange for sharing profits and losses of sales of Afrezza, with 65% for Sanofi and 35% for MannKind. 
The firm's oncology drug candidates, MKC1106-PP for prostate and MKC1106-MT for advanced stage melanoma (in phase II study), use the body's immune system (immunotherapy) to target specific melanoma antigen (PRAME) and prostate specific membrane antigen (PSMA).
The firm has stated that it is developing a next generation inhalation technology, a miniature, breath-powered inhaler used in combination with single-use cartridges containing pre-metered doses. Initial pharmacokinetic studies were followed by studies of safety and efficiency involving technosphere formulations of different therapeutic proteins.
In January 2011, a lawsuit was filed against MannKind Corporation alleging that MannKind's stock price was artificially inflated as a result of untrue or materially misleading statements related to MannKind's communications with the FDA about its new product Afrezza, resulting in the Mannkind Co. stock being deemed "toxic". A settlement of $16 million was reached in 2012.
