Protalix BioTherapeutics is an Israeli pharmaceutical company that manufactures a plant-based enzyme, taliglucerase alfa, which has received U.S. Food and Drug Administration approval for the treatment of Gaucher disease.

Corporate history

Protalix BioTherapeutics was established in 1993. [3] It was founded by Yoseph Shaaltiel, who received his Ph.D. in Plant Biochemistry from the Weizmann Institute in Israel and served in the Biology Department of the Israel Defense Forces' Biological and Chemical Center. [4] One of the earliest and largest investors in the company was Phillip Frost. [5] Protalix has two Nobel Prize winners (Chemistry) in its Scientific Advisory Board, Roger Kornberg Ph.D and Prof. MD. Aaron Ciechanover.

In its early days Protalix operated out of a warehouse in the town of Qiryat Shemona in northern Israel. [6] On July 19, 2005, Protalix Biotherapeutics announced the closing of a $5.3 million private placement of its series C preferred stock. [7] Protalix entered into a partnership agreement with Teva Pharmaceutical Industries in 2006 for the development of two proteins [8] and in 2009 signed a collaboration agreement with Pfizer for the development and commercialization of its taliglucerase alfa treatment. [9] Also in 2009, Protalix reported that Frost & Sullivan presented the company with its 2009 European Orphan Diseases Market Product Innovation of the Year Award. [10] In 2011 Protalix announced that the U.S. Food and Drug Administration had approved the company's manufacturing facility in Karmiel. [11]

Protalix initially became a public company through a reverse merger process with Orthodontix, a company which was at the time traded "over the counter" on the NASDAQ. [12] This merger was completed on December 31, 2006, and is notable as one of the largest reverse mergers executed, valuing the joint entity at almost $1 billion. [13] It subsequently applied for a listing on the AMEX, and sold 10 million shares in a public offering.

Products

Protalix has been using cultured plant cells to manufacture biopharmaceuticals. As of 2017, Protalix has one FDA approved product sold by Pfizer in the U.S. and currently developing four products:

Deoxyribonuclease refers to a group of glycoprotein endonucleases which are enzymes that catalyze the hydrolytic cleavage of phosphodiester linkages in the DNA backbone, thus degrading DNA. The role of the DNase enzyme in cells includes breaking down extracellular DNA (ecDNA) excreted by apoptosis, necrosis, and neutrophil extracellular traps (NET) of cells to help reduce inflammatory responses that otherwise are elicited. A wide variety of deoxyribonucleases are known and fall into one of two families, which differ in their substrate specificities, chemical mechanisms, and biological functions. Laboratory applications of DNase include purifying proteins when extracted from prokaryotic organisms. Additionally, DNase has been applied as a treatment for diseases that are caused by ecDNA in the blood plasma. Assays of DNase are emerging in the research field as well.

<span class="mw-page-title-main">Gaucher's disease</span> Medical condition

Gaucher's disease or Gaucher disease (GD) is a genetic disorder in which glucocerebroside accumulates in cells and certain organs. The disorder is characterized by bruising, fatigue, anemia, low blood platelet count and enlargement of the liver and spleen, and is caused by a hereditary deficiency of the enzyme glucocerebrosidase, which acts on glucocerebroside. When the enzyme is defective, glucocerebroside accumulates, particularly in white blood cells and especially in macrophages. Glucocerebroside can collect in the spleen, liver, kidneys, lungs, brain, and bone marrow.

Fabry disease, also known as Anderson–Fabry disease, is a rare genetic disease that can affect many parts of the body, including the kidneys, heart, brain, and skin. Fabry disease is one of a group of conditions known as lysosomal storage diseases. The genetic mutation that causes Fabry disease interferes with the function of an enzyme that processes biomolecules known as sphingolipids, leading to these substances building up in the walls of blood vessels and other organs. It is inherited in an X-linked manner.

These pancreatic problems may be due to cystic fibrosis, surgical removal of the pancreas, long term pancreatitis, pancreatic cancer, or MODY 5, among others. The preparation is taken by mouth.

Pharming, a portmanteau of farming and pharmaceutical, refers to the use of genetic engineering to insert genes that code for useful pharmaceuticals into host animals or plants that would otherwise not express those genes, thus creating a genetically modified organism (GMO).
