Amylin Pharmaceuticals, Inc. is a biopharmaceutical founded in 1987 that was based in San Diego, California. The company was engaged in the discovery, development, and commercialization of drug candidates for the treatment of diabetes, obesity, and other diseases. Amylin produced three drugs: Symlin (pramlintide acetate), Byetta (exenatide) and Bydureon (exenatide extended release).
In 1987, Amylin Pharmaceuticals was co-founded by Howard E. Greene Jr., former CEO of San Diego biotech pioneer Hybridtech, to develop a treatment for diabetes from a synthetic analog of amylin. [3] Amylin was discovered by researchers at Oxford University earlier that year. [4] Greene served as CEO from 1987 to 1996. Amylin completed its IPO in 1992.[ citation needed ]
Amylin, in its natural form, is sticky, clumping on needles and forming little rocks[ clarification needed ] in the pancreas. To create a synthetic version that was more reliable and easy to work with, researchers at Amylin Pharmaceuticals altered amino acids in the molecule. The result was a new drug named pramlintide. [5]
In 1995, Amylin Pharmactietucals signed an agreement with Johnson & Johnson's LifeScan division to further develop pramlintide. [6] A Phase II study made public in January 1997 showed that pramlintide was safe to mix with leading short-acting and intermediate-acting commercial insulin products, with preliminary results suggesting it might improve glycemic control. [7]
Initial Phase III trial results released in August 1997 demonstrated statistically significant results for type 1 (juvenile-onset) diabetes, helping modestly to improve glucose control without increasing the risk of hypoglycemia (low blood sugar) while also improving weight and cholesterol levels. In patients with adult-onset type 2 diabetes, pramlintide showed significant benefits at six months but not after 12 months. [8] In March 1998, seven months before the next trial data were due, Johnson & Johnson terminated its partnership with Amylin.[ citation needed ]
Joseph C. Cook Jr., a 28-year veteran at Eli Lilly & Co. and an Amylin board member since 1994, came out of retirement in 1998, taking the title of chief executive officer. Cook reduced the company's workforce by 75 percent to conserve cash and raised capital from investors to keep Symlin moving through the regulatory pipeline. [4]
In October 2001, Amylin received an approvable letter for Symlin from the FDA, requiring additional clinical data addressing concerns of severe hypoglycemia in type 1 diabetics. [9] In December 2003, the FDA issued a second approvable letter requesting further clinical data to identify a patient population and method of use for Symlin where there is no increased risk of significant hypoglycemia or where there is an added benefit that clearly counterbalances any potential for increases in episodes of hypoglycemia. [10] In March 2005, Symlin was approved by the FDA for use in diabetics who have difficulty maintaining glycemic control. [11]
In October 1996, Dr. John Eng licensed to Amylin exendin-4, a peptide he had isolated in the venom of a Gila monster. [12] Exendin-4 is similar to the human gut hormone GLP-1, which is responsible for regulating insulin and glucagon release. [13] Unlike human GLP-1, however, exendin-4 has a half-life of several hours, making it a much better drug candidate. [12] Amylin developed exenatide, a synthetic version of exendin-4. In 2002, Eli Lilly signed an agreement with Amylin for $325 million to partner in development of exenatide. [14] In May 2005, Byetta (commercial name for exenatide) was approved in the United States. [15]
In July 2012, Bristol-Myers Squibb announced it would acquire Amylin Pharmaceuticals for $5.3 billion. [16] As part of the acquisition, AstraZeneca made a $3.4 billion cash payment to make Amylin a wholly owned subsidiary within the existing BMS/AZ joint venture in diabetes. [17] In April 2013, Bristol-Myers Squibb announced it would close Amylin's San Diego operations by the end of 2014 and merge the Amylin manufacturing facility in West Chester, Ohio, and all field-based sales personnel into Bristol-Myers Squibb operations. [18] [19]
In December 2013, AstraZeneca purchased the Bristol-Myers Squibb share of the diabetes joint venture, and as a result, became the sole owner of all former Amylin products and business, including the manufacturing facility in West Chester, Ohio. [20] [21]
On February 4, 2014, the U.S. FDA approved Myalept (metreleptin), an analog of human leptin, [22] as replacement therapy to treat the complications of leptin deficiency, in addition to diet, in patients with congenital generalized or acquired generalized lipodystrophy. [23] Metraleptin was originally developed at Amylin Pharmaceuticals. [24] In November 2014, Aegerion Pharmaceuticals made a $325 million cash payment to AstraZeneca to acquire and commercialize metreleptin. [25]
Drugs used in diabetes treat diabetes mellitus by decreasing the glucose level in the blood. With the exception of insulin, most GLP receptor agonists, and pramlintide, all are administered orally and are thus also called oral hypoglycemic agents or oral antihyperglycemic agents. There are different classes of hypoglycemic drugs, and their selection depends on the nature of diabetes, age, and situation of the person, as well as other factors.

Glucagon-like peptide-1 (GLP-1) receptor agonists, also known as GLP-1 analogs, GLP-1DAs or incretin mimetics, are a class of drugs that reduce blood sugar and energy intake by activating the GLP-1 receptor. They mimic the actions of the endogenous incretin hormone GLP-1 that is released by the gut after eating.
Acquired generalized lipodystrophy is a rare skin condition that appears during childhood or adolescence, characterized by fat loss affecting large areas of the body, particularly the face, arms, and legs. There are 4 types of lipodystrophy based on its onset and areas affected: acquired or inherited, and generalized or partial. Both acquired or inherited lipodystrophy present as loss of adipose tissues, in the absence of nutritional deprivation. The near-total loss of subcutaneous adipose tissue is termed generalized lipodystrophy while the selective loss of adipose tissues is denoted as partial lipodystrophy. Thus, as the name suggests, AGL is a near-total deficiency of adipose tissues in the body that is developed later in life. It is an extremely rare disease that only about 100 cases are reported worldwide. There are three main etiologies of AGL suspected: autoimmune, panniculitis-associated, or idiopathic. After its onset, the disease progresses over a few days, weeks, months, or even in years. Clinical presentations of AGL are similar to other lipodystrophies, including metabolic complications and hypoleptinemia. Treatments are also similar and mainly supportive for symptomatic alleviation. Although HIV- or drug-induced lipodystrophy are a type of acquired lipodystrophy, its origin is very specific and distinct hence is usually not discussed with AGL.
Insulin degludec (INN/USAN) is an ultralong-acting basal insulin analogue that was developed by Novo Nordisk under the brand name Tresiba. It is administered via subcutaneous injection once daily to help control the blood sugar level of those with diabetes. It has a duration of action that lasts up to 42 hours, making it a once-daily basal insulin, that is one that provides a base insulin level, as opposed to the fast- and short-acting bolus insulins.
Metreleptin, sold under the brand name Myalept among others, is a synthetic analog of the hormone leptin used to treat various forms of dyslipidemia.
