Lanreotide, sold under the brand name Somatuline among others, is a medication used in the management of acromegaly and symptoms caused by neuroendocrine tumors, most notably carcinoid syndrome. It is a long-acting analogue of somatostatin, like octreotide.

Contents

Lanreotide (as lanreotide acetate) is manufactured by Ipsen. It is available in several countries, including the United Kingdom, Australia and Canada, and was approved for sale in the United States by the Food and Drug Administration (FDA) on August 30, 2007. [2]

Medical uses

Lanreotide is used in the treatment of acromegaly, due to both pituitary and non-pituitary growth hormone-secreting tumors, and the management of symptoms caused by neuroendocrine tumors, particularly carcinoid tumor - no longer called this. It's a 30-year-old term before they realised that the tumours were actually malignant cancer not simply tumours which can be non-cancerous, tell your doctor/ocologist/surgeon to update his knowledges and VIPomas. In the United States and Canada, lanreotide is only indicated for the treatment of acromegaly. In the United Kingdom, it is also indicated in the treatment of thyrotrophic adenoma, [3] a rare tumor of the pituitary gland which secretes TSH.

Lanreotide also shows activity against non-endocrine tumors, and, along with other somatostatin analogues, is being studied as a possible general antitumor agent. [4] [5]

In December 2014, the US FDA approved lanreotide for the treatment of people with unresectable, well or moderately differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs). [6]

It is used for polycystic liver disease.[ medical citation needed ] It has also been shown that it reduces the volume by 264mls on average.[ medical citation needed ]

Side effects

The main side effects of lanreotide treatment are mild to moderate pain at the injection site and gastrointestinal disturbances, such as diarrhea, nausea and vomiting. Isolated cases of gallstone formation have been associated with use of lanreotide, particularly over long periods of time. [3]

Pharmacology

Lanreotide is a synthetic analogue of somatostatin, a naturally occurring inhibitory hormone which blocks the release of several other hormones, including growth hormone, thyroid-stimulating hormone (TSH), insulin and glucagon. Lanreotide binds to the same receptors as somatostatin, although with higher affinity to peripheral receptors, and has similar activity. However, while somatostatin is quickly broken down in the body (within minutes), [7] lanreotide has a much longer half-life, and produces far more prolonged effects.[ medical citation needed ]

Formulations

Lanreotide is available in two formulations: a sustained release formulation (sold under the trade name 'Somatuline LA'), which is injected intramuscularly every ten or fourteen days, [3] and an extended release formulation (UK trade name 'Somatuline Autogel', or 'Somatuline Depot' in the US), which is administered subcutaneously once a month. [8]

Self-assembling properties

Lanreotide has been shown to spontaneously self-assemble into monodisperse nanotubes of 24.4 nm diameter [9] and has been thereafter used as a fruitful and versatile model system in several biophysical studies.[ citation needed ]

<span class="mw-page-title-main">Growth hormone</span> Peptide hormone, that stimulates growth

Growth hormone (GH) or somatotropin, also known as human growth hormone in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. GH also stimulates production of Insulin-like growth factor 1 (IGF-1) and increases the concentration of glucose and free fatty acids. It is a type of mitogen which is specific only to the receptors on certain types of cells. GH is a 191-amino acid, single-chain polypeptide that is synthesized, stored and secreted by somatotropic cells within the lateral wings of the anterior pituitary gland.

A major organ of the endocrine system, the anterior pituitary is the glandular, anterior lobe that together with the posterior lobe makes up the pituitary gland (hypophysis) which, in humans, is located at the base of the brain, protruding off the bottom of the hypothalamus.

<span class="mw-page-title-main">Somatostatin</span> Peptide hormone that regulates the endocrine system

Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin inhibits insulin and glucagon secretion.

Pituitary adenomas are tumors that occur in the pituitary gland. Most pituitary tumors are benign, approximately 35% are invasive and just 0.1% to 0.2% are carcinomas. Pituitary adenomas represent from 10% to 25% of all intracranial neoplasms and the estimated prevalence rate in the general population is approximately 17%.

Octreotide, sold under the brand name Sandostatin among others, is an octapeptide that mimics natural somatostatin pharmacologically, though it is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone. It was first synthesized in 1979 by the chemist Wilfried Bauer, and binds predominantly to the somatostatin receptors SSTR2 and SSTR5.

A carcinoid is a slow-growing type of neuroendocrine tumor originating in the cells of the neuroendocrine system. In some cases, metastasis may occur. Carcinoid tumors of the midgut are associated with carcinoid syndrome.

Carcinoid syndrome is a paraneoplastic syndrome comprising the signs and symptoms that occur secondary to neuroendocrine tumors. The syndrome is caused by neuroendocrine tumors most often found in the gut releasing biologically active substances into the blood causing symptoms such as flushing and diarrhea, and less frequently, heart failure, vomiting and bronchoconstriction.

<span class="mw-page-title-main">Neuroendocrine tumor</span> Medical condition

Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine (hormonal) and nervous systems. They most commonly occur in the intestine, where they are often called carcinoid tumors, but they are also found in the pancreas, lung, and the rest of the body.

Somatostatinomas are a tumor of the delta cells of the endocrine pancreas that produces somatostatin. Increased levels of somatostatin inhibit pancreatic hormones and gastrointestinal hormones. Thus, somatostatinomas are associated with mild diabetes mellitus, steatorrhoea and gallstones, and achlorhydria. Somatostatinomas are commonly found in the head of pancreas. Only ten percent of somatostatinomas are functional tumours [9], and 60–70% of tumours are malignant. Nearly two-thirds of patients with malignant somatostatinomas will present with metastatic disease.

Pegvisomant, sold under the brand name Somavert, is a growth hormone receptor antagonist used in the treatment of acromegaly. It is primarily used if the pituitary gland tumor causing the acromegaly cannot be controlled with surgery or radiation, and the use of somatostatin analogues is unsuccessful, but is also effective as a monotherapy. It is delivered as a powder that is mixed with water and injected under the skin.

An octreotide scan is a type of SPECT scintigraphy used to find carcinoid, pancreatic neuroendocrine tumors, and to localize sarcoidosis. It is also called somatostatin receptor scintigraphy (SRS). Octreotide, a drug similar to somatostatin, is radiolabeled with indium-111, and is injected into a vein and travels through the bloodstream. The radioactive octreotide attaches to tumor cells that have receptors for somatostatin. A gamma camera detects the radioactive octreotide, and makes pictures showing where the tumor cells are in the body, typically by a SPECT technique. A technetium-99m based radiopharmaceutical kit is also available.

Acromegaly is a disorder that results in excess growth of certain parts of the human body. It is caused by excess growth hormone (GH) after the growth plates have closed.

Other symptoms may include joint pain, thicker skin, deepening of the voice, headaches, and problems with vision. Complications of the disease may include type 2 diabetes, sleep apnea, and high blood pressure.
