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:

Gauchers disease 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.

Sanofi French pharmaceutical company

Sanofi S.A. is a French multinational healthcare company headquartered in Paris, France. It is the world's fifth-largest pharmaceutical company by prescription sales. Originally, the corporation was established in 1973 and merged with Synthélabo in 1999 to form Sanofi-Synthélabo. In 2004, Sanofi-Synthélabo merged with Aventis and renamed to Sanofi-Aventis, which were each the product of several previous mergers. It changed its name back to Sanofi in May 2011. The company is a component of the Euro Stoxx 50 stock market index. Genzyme is a fully owned subsidiary of Sanofi and the world’s third-largest biotechnology company.

Fabry disease Rare human genetic lysosomal storage disorder

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, 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.

Glycogen storage disease type II Medical condition

Glycogen storage disease type II, also called Pompe disease, is an autosomal recessive metabolic disorder which damages muscle and nerve cells throughout the body. It is caused by an accumulation of glycogen in the lysosome due to deficiency of the lysosomal acid alpha-glucosidase enzyme. It is the only glycogen storage disease with a defect in lysosomal metabolism, and the first glycogen storage disease to be identified, in 1932 by the Dutch pathologist J. C. Pompe.

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). Pharming is also known as molecular farming, molecular pharming or biopharming.

Vertex Pharmaceuticals American pharmaceutical company

Vertex Pharmaceuticals, Inc. is an American biopharmaceutical company based in Boston, Massachusetts. It was one of the first biotech firms to use an explicit strategy of rational drug design rather than combinatorial chemistry. It maintains headquarters in South Boston, Massachusetts, and three research facilities, in San Diego, California, and Milton Park, near Oxford, England.

Dornase alfa

Dornase alfa is a highly purified solution of recombinant human deoxyribonuclease I (rhDNase), an enzyme which selectively cleaves DNA. Dornase alfa hydrolyzes the DNA present in sputum/mucus of cystic fibrosis patients and reduces viscosity in the lungs, promoting improved clearance of secretions. This protein therapeutic agent is produced in Chinese hamster ovary cells.

Glucocerebrosidase

β-Glucocerebrosidase is an enzyme with glucosylceramidase activity that is needed to cleave, by hydrolysis, the beta-glucosidic linkage of the chemical glucocerebroside, an intermediate in glycolipid metabolism that is abundant in cell membranes. It is localized in the lysosome, where it remains associated with the lysosomal membrane. β-Glucocerebrosidase is 497 amino acids in length and has a molecular weight of 59,700 Daltons.

Imiglucerase is a medication used in the treatment of Gaucher's disease.

Genzyme Company

Sanofi Genzyme is an American biotechnology company based in Cambridge, Massachusetts. Since its acquisition in 2011, Genzyme has been a fully owned subsidiary of Sanofi. In 2010, Genzyme was the world’s third-largest biotechnology company, employing more than 11,000 people around the world. As a subsidiary of Sanofi, Genzyme has a presence in approximately 65 countries, including 17 manufacturing facilities and 9 genetic-testing laboratories. Its products are also sold in 90 countries.

Approved by the United States Food and Drug Administration (FDA) on 27 April 2017, this is the first treatment for a neuronal ceroid lipofuscinosis of its kind, acting to slow disease progression rather than palliatively treat symptoms by giving patients the TPP1 enzyme they are lacking.
