But these days, new botanical drugs are in demand. Coming up with them is an important scientific challenge. We introduce two Israeli biotech companies who are successfully meeting that challenge with cutting-edge development efforts.<br><br>In Israel\u2019s Arava region, a company called&nbsp;<strong>Algatech<\/strong>&nbsp;is tapping microscopic algae for a powerful antioxidant called astaxanthin. More than half way across the country, in Yavne, a company called&nbsp;<strong>MediWound<\/strong>&nbsp;is extracting enzymes from pineapple stems to make unique products that can treat burns and chronic wounds. What do the two companies have in common?<br><br>Both are groundbreaking Israeli biotech companies that successfully develop and manufacture original drugs from plant life and market them worldwide \u2013 all with the assistance of the Israel Innovation Authority.<br><br><strong>Dr. Zeev Even-Chen<\/strong>, a member of the Authority\u2019s array of professional evaluators, explains: \u201cUnlike conventional drugs, the medications we call \u2018botanical drugs\u2019 are usually a mix of substances. Some of the substances are plant extracts, but not all of them are. The elements typically act in synergy \u2013 that is, in combination \u2013 to make the active ingredients more effective.\u201d<br><br>Today in the western world, stringent regulations require manufactured drugs to show no significant variation over time in their characteristics or their effect. Additionally, the manufacturing process must meet the pharmaceutical industry\u2019s accepted standards as codified in the guidelines of the FDA (the American Food and Drug Administration). And just like synthetic drugs, plant-extracted drugs also need to be proven effective against a particular disease.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Supplement versus Drug: What&#8217;s the Difference?<\/h3>\n\n\n\n<p>Traditional medicine passed down verbally from generation to generation through centuries of history, uses plant-based substances to treat wounds, pain, and disease. But our ancestors didn\u2019t understand the scientific complexities involved. They didn\u2019t know what quality or ingredients the plant possessed that cured the patient of what ailed them, or how it happened. If a particular plant was found to relieve a headache or stomach ache, for example, people just used it.<br><br>The situation nowadays is entirely different. Developing a botanical drug based on traditional medicine, or based on a particular plant material that is known to contain a family of beneficial substances, requires attention to many details. A company has to know how to formulate the&nbsp;<strong>drug correctly<\/strong>, dispense it accurately, and keep it stable. Not to mention patenting it, respecting regulations, and being economically realistic.<br><strong>Plant-sourced substances can be used to promote human health in three different ways:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>As part of our nourishment (a health food)<\/li>\n\n\n\n<li>As a food supplement<\/li>\n\n\n\n<li>As a drug<\/li>\n<\/ul>\n\n\n\n<p>For each category, the supervision is distinct in both scope and regulations.<br><br>While health foods are relatively simple to understand, the difference between supplements and drugs can be more complicated. When plant products are marketed as dietary supplements, they come with no specific medical guidelines. They claim only to be \u201cbeneficial to health\u201d in a general sense, and like any other food, they simply need to provide proof that they aren\u2019t toxic. Dietary supplements do not, and must not, come with a promise to heal any illness or disease.<br><br>On the other hand, if a product is approved as a botanical drug, it comes with clear medical guidelines for use just as any other approved drug does.<br><br>Regulation lays down absolute restrictions for botanical drugs: Firstly, since such drugs are a mix of substances, each lot must be tested for compliance with specifications. And there must be a sort of \u2018fingerprint\u2019 showing which lot each purchased dosage belongs to.<br><br>Also, the FDA requires controlled growing conditions \u2014kept stable artificially \u2014 because as seasons change and growing conditions vary, the same plant may not always yield an identical drug. If left to nature, the plant won\u2019t always have the same content and concentration of active and inactive substances.<br><br>These two demands can place a burden on researchers and entrepreneurs who develop botanical drugs. According to Dr. Even-Chen, the number of FDA-approved botanical drugs is small; as well as the number of botanical drugs approved for use in Israel. Israeli regulations have adopted principles of the Food and Drug Administration, and of its European equivalent the European Medicines Agency. As winning approval for botanical drugs remains so difficult, most researchers and entrepreneurs focus on developing and manufacturing food supplements instead. Endorsement for dietary supplements is immeasurably easier to obtain.<br><br>As a result, today\u2019s pharmacy shelves are filled with long rows of products containing active substances \u2013 substances such as lycopene or antioxidant polyphenols \u2013 but the products are sold as dietary supplements, not drugs.<br><br>Another example, turmeric, has long been recognized as an active agent against non-bacterial inflammations. Several companies sell capsules of turmeric extract as a food supplement. Garlic and onion pills are also sold as dietary supplements. There are various types of algae from which all sorts of active materials are extracted and sold as food supplements.<br><br>\u201cOccasionally it happens that from a botanical source, they isolate an active substance that can be used as a drug. Then its chemical structure can be analyzed and then researchers need to find how to obtain an identical but synthetic substance, in case the botanical material it isn\u2019t always available \u2014 or merely to work more naturally and comfortably under regulation,\u201d explains Dr. Even-Chen.<br><br>For example, the drug Taxol, which is used in chemotherapy for breast cancer, was first discovered in the bark of the Pacific yew tree. To extract enough of that substance, someone would have to plant yew forests across the Amazon. Instead, they identified the molecular structure of the active agent, and today the drug is chemically synthesized without the yew trees.<br><br>\u201cThe industry in Israel is very creative, and it turns out many studies,\u201d Dr. Even-Chen says in conclusion, \u201cwhether the goal is producing \u2018botanical foods\u2019 that are spiked with active substances or whether it\u2019s new technologies in the life sciences from the Technion and other institutes.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Algae \u2013 An Oasis in the Desert<\/h3>\n\n\n\n<p>Algatech, a biotech firm established in 1998, develops and manufactures active substances from microscopic algae. The microalgae are grown in a closed, sustainable, environmentally friendly system that harnesses the nourishment of desert sunlight.<br><br>Algatech is a global leader in the manufacture and supply of one of the most powerful antioxidants in existence \u2013 astaxanthin, a natural substance based on a one-celled species of microalgae called Haematococcus Pluvialis. The material is marketed under the brand name AstaPure.<br><br>Microalgae are extremely adaptable microorganisms that grow in a variety of locations and are naturally rich in a wide range of healthy and beneficial substances. To date, scientists have identified some thirty thousand different species of microscopic algae that produce unique and potentially useful chemicals. Products based on micro algae have a broad variety of unique applications in the food industry as nutritional supplements, as drugs, and in cosmetics. However, not very many species are being used for practical and commercial purposes due to practical concerns. Commercial growers of microalgae need to find a delicate balance between the necessary growing technology, the available growing location, and the desired final product. The task demands time, capital, and versatility.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"596\" height=\"447\" src=\"https:\/\/innovationisrael.org.il\/en\/wp-content\/uploads\/sites\/3\/2023\/03\/Extraordinary-Extracts.jpg\" alt=\"\" class=\"wp-image-2651\" srcset=\"https:\/\/innovationisrael.org.il\/en\/wp-content\/uploads\/sites\/3\/2023\/03\/Extraordinary-Extracts.jpg 596w, https:\/\/innovationisrael.org.il\/en\/wp-content\/uploads\/sites\/3\/2023\/03\/Extraordinary-Extracts-300x225.jpg 300w\" sizes=\"(max-width: 596px) 100vw, 596px\" \/><\/figure><\/div>\n\n\n<p><br>&nbsp;<\/p>\n\n\n\n<p>As&nbsp;<strong>Hagai Stadler<\/strong>, CEO of Algatech, explains, the company was founded by members of Kibbutz Ketura in the Negev who sought an economically viable path compatible with the Zionist vision of settling the Negev and making the desert bloom. The kibbutz wisely found ways of leveraging the desert climate by turning its apparent disadvantages \u2013 isolation and active solar radiation \u2013 into advantages. Thus, the establishment of APC (Arava Power Company), which has become one of Israel\u2019s largest solar energy companies, as well as Algatech, one of the world\u2019s most advanced factories in the manufacture of active substances extracted from microalgae. The Algatech factory extends across a broad area of closed photobioreactor systems containing more than 600 kilometers of glass tubes, all fully monitored throughout the production process. The company\u2019s initial technology was developed at Ben-Gurion University\u2019s Microalgal Biotechnology Laboratory by Prof. Sammy Boussiba, one of the world\u2019s foremost researchers in the field. Professor Boussiba still serves as head of the laboratory.<br><br>The growing process proceeds in several stages, using both clean rooms and open spaces. In the initial \u201cgreen stage,\u201d the algae benefit from optimal conditions for growth and reproduction. During the next stage, the \u201cred stage,\u201d the algae\u2019s comfort is \u201cviolated\u201d as growers introduce more stressful growing conditions. In response to the stress, the algae boost their production of the pigment astaxanthin, which turns the algae red.<br><br><strong>Efrat Kat<\/strong>, Algatech VP of Marketing &amp; Sales, explains: \u201cThe moment the algae experience stress, they produce astaxanthin, which allows them to survive under extreme conditions. In nature, the algae are found in cisterns and puddles, and the stress comes when the water is gone. The drying algae turn into cysts and create astaxanthin to survive until the next rainy season. Astaxanthin is the same pigment that makes salmon salmon-colored. Studies say that it\u2019s also the reason salmon can survive swimming upstream for hundreds of kilometers without food. Astaxanthin is anti-inflammatory, and it\u2019s one of the most powerful antioxidants in nature. More than 400 clinical and paraclinical studies demonstrate that astaxanthin is good for our health, and research has only begun.\u201d<br><br>Kat adds: \u201cManufacturers of nutritional supplements in more than 40 countries buy astaxanthin from us as a raw material. Our biggest markets are Japan, the US, and Europe. We also sell to large industrial companies, including Fujifilm Holdings in Japan \u2013 a huge corporation. Fujifilm decided to make astaxanthin its flagship product, and it launched a line of astaxanthin cosmetics and nutritional supplements. Now it\u2019s one of Japan\u2019s leading companies in that market.\u201d<br><br>\u201cProducing natural substances out of algae is complex,\u201d Stadler continues, \u201cYou need many capabilities- biological, technical, engineering, processing, extraction, QA +QC, regulatory compliance, patent expertise, marketing channels, and profound market understanding. The process is very involved. It takes time, knowledge and capital \u2013 as well as quite a bit of luck. Today, Algatech is working at various universities to develop more substances. In years to come, we plan to commercialize some of the new active substances we\u2019ve developed in recent years.<br><br>\u201cEach type of algae is a world unto itself. It calls for its own growing technologies and know-how. At Algatech we\u2019re multidisciplinary, we\u2019re experienced, we have various techniques for growing and processing algae, and most important is our team of specialists \u2013 world-class marine biologists, biotechnologists, chemists, operators, and technicians. With all these strings to our bow, we can reach high efficiency and a good R&amp;D success rate for new algae products.\u201d<br><br>\u201cMicroalgae are where the food chain starts,\u201d Stadler says. \u201cThey\u2019re primordial. Over the years they\u2019ve had to compete with bacteria, mold, and other entities to get food, so they\u2019ve developed mechanisms and components that help them stay alive. Some of those components can help humanity meet future challenges and improve the health and welfare of both people and animals.<br><br>\u201cIn the 2030s, we could be looking at a 40% shortage of protein. But by now we have algae that contain more than fifty percent protein, including all the amino acids humans require. So, some of the world\u2019s major corporations are interested. With advanced technologies, an industry can turn algae into the chief supplier of protein in the coming decade.<br><br>\u201cAlgatech is a member company of the EU FoodConnects consortium. That\u2019s a \u20ac1.5 billion consortium for developing new food sources, and the issue of protein takes a central place there. PepsiCo, Nestl\u00e9, Roquette, and Dohler are all in the consortium too.\u201d<br><br>During the development process, Algatech carried out projects with the backing of the Chief Scientist at the Israel Innovation Authority. \u201cWe owe our successes, to a large extent, to the Israel Innovation Authority, to Ofra Lotan at the head of it, and to its professional staff, for supporting Algatech in recent years. We have to give credit to the Authority\u2019s staff for taking us seriously, and for all they\u2019ve invested in assessing and reviewing our projects. The assistance from IIA is what has led Algatech to the impressive achievements we have made,\u201d Stadler stresses. \u201cThis year we intend to launch a new product, algae extract, that tackles fatty liver disease and metabolic syndrome. The product took years of complex, costly development, and our ability to reach this point, just inches from the finish line, is largely thanks to the faith and financial support of the Israel Innovation Authority.<br><br>\u201cThe processes involved in R&amp;D are not trivial; they demand lots of ability, research effort, and financial investment. Algatech is considered a world leader in microalgae today, and a source of pride in the field of Israeli technology. In the southern Arava, Algatech is a chief provider of jobs and an engine of economic growth. If it\u2019s going to continue expanding as a cutting-edge business with a genuine power to contribute to global welfare \u2013 while located in one of the country\u2019s most remote regions \u2013 government support is necessary. We hope that the Israel Innovation Authority will continue to help our company in our future research and development projects.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Innovation in the Operating Room<\/h3>\n\n\n\n<p>MediWound is an Israeli biotech company that develops and markets unique products based on enzymes extracted from the stems of pineapple plants \u2013 for the treatment of burns and chronic wounds. From fully developing and manufacturing drugs at its sterile production plant in Yavne to directly marketing them worldwide, it is among the few Israeli companies that independently manage the entire value chain for their products. In keeping with the current trend in the medical world, MediWound seeks to replace surgical and traumatic treatment of burns with topical, non-invasive treatment.<br><br><strong>NexoBrid<\/strong>, an innovative drug developed by MediWound, makes it possible to treat burn wounds through the removal of injured tissue within hours, all in the patient\u2019s hospital bed and without harming healthy skin. Such treatment saves the patient many operations and potential scars. The drug is likely to play a significant role in mass-casualty incidents where a hospital\u2019s capacity to perform operations is severely limited. In such scenarios, swift medical intervention is critical.<br><br>The company\u2019s CEO, Gal Cohen, relates the story of MediWound: \u201cProfessor Lior Rosenberg founded the company. He\u2019d been at an international conference where an American doctor, named Gerald Klein, gave a talk about treating burns using enzymes from the stem of the pineapple plant. At that time, such an idea flew in the face of conventional medical wisdom. So Dr. Klein purposely burned himself, and he invited members of the audience to check him after several hours and see what the treatment did. Professor Rosenberg accepted the invitation. The results he witnessed made him want to research this particular enzyme, and from his research, MediWound was established in 2000. For more than a decade, the company has overseen NexoBrid\u2019s development. It\u2019s been a painstaking project, but NexoBrid has proven itself in a series of trials on hundreds of patients around the world. It\u2019s safe and efficient, it\u2019s revolutionary, and we\u2019ve won approval to market it.\u201d<br><br>The company\u2019s two flagship products, NexoBrid and EscharEx, are founded on MediWound\u2019s patented enzymatic technology and are considered breakthroughs in medicine. The enzymes are extracted from pineapple plants through an intricate, unique, and controlled process. The products help efficiently break down certain proteins found in injured tissue, without causing harm to the healthy skin. The enzymes can also contribute to lessening the intensity of the inflammation process \u2013 a process that, if it persists, can cause scarring. Thus, the enzymes reduce the number of scars among patients.<br><br>The company\u2019s vision: Optimal treatment that is swift, efficient, and non-surgical, for patients everywhere.<br><br>NexoBrid is a breakthrough because among the products based on botanical proteins, it is one of the few approved for use as a biological drug, and because of the enormous analytical challenge involved in ultimately bringing it to market. NexoBrid has been approved for marketing in Europe and Israel as a novel orphan drug (a drug that only a small number of patients need) for removing dead tissue found on medium to severe burns.<br><br>The drug comes in gel form, and a single application removes burned tissue without harming healthy skin. Clinical trials have proven that it significantly reduces the frequency and extent of operations and scars. NexoBrid is expected to serve as an essential tool in treating victims of mass-casualty incidents where currently the hospitals have too few operating rooms and surgeons for simultaneously treating all the burn victims. Already, NexoBrid is being used by hundreds of doctors in treating patients at dozens of burn centers worldwide. The drug has been approved for use by the EMA (European Medicines Agency) and is marketed across Europe, Israel, and Argentina. Numerous health agencies elsewhere are testing it. In light of NexoBrid\u2019s capabilities, the US government has agreed to finance the drug\u2019s continued development in the US and, to be prepared for mass-casualty incidents, it will build an inventory before approval.<br><br>The second product,&nbsp;<strong>EscharEx<\/strong>, is an advanced drug for removing dead tissue from chronic and hard-to-heal wounds. The drug can aid in the treatment of diabetic ulcers, venous insufficiency ulcers, hard-to-heal wounds, and other afflictions. It is intended for use in conjunction with other existing products in the chronic wound market which require a clean wound surface to achieve complete healing.<br><br>EscharEx is designed to treat chronic wounds that cause patients great suffering and even disability. The number of patients with such injuries increases year on year as the population ages and as diabetes and obesity, two causes of chronic wounds, become more frequent. The product has undergone a successful trial on two chronic wound patients. MediWound, with the support of the Israel Innovation Authority, continues to advance the development of EscharEx to obtain approval for commercial use in this growing market.<br><br>Aside from those two drugs, the company has begun developing another product (also based on pineapple enzymes), administered via injection for patients who suffer from connective tissue disorders such as severe scarring.&nbsp;<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"645\" height=\"405\" src=\"https:\/\/innovationisrael.org.il\/en\/wp-content\/uploads\/sites\/3\/2023\/03\/Extraordinary-Extracts-2.jpg\" alt=\"\" class=\"wp-image-2653\" srcset=\"https:\/\/innovationisrael.org.il\/en\/wp-content\/uploads\/sites\/3\/2023\/03\/Extraordinary-Extracts-2.jpg 645w, https:\/\/innovationisrael.org.il\/en\/wp-content\/uploads\/sites\/3\/2023\/03\/Extraordinary-Extracts-2-300x188.jpg 300w\" sizes=\"(max-width: 645px) 100vw, 645px\" \/><\/figure><\/div>\n\n\n<p><\/p>\n\n\n\n<p>Dr. Yaron Shoham treats victims of burn incidents in Romania using NexoBrid (courtesy)<br><br>\u201cThe Israeli pharma industry has developed some unique drugs, but NexoBrid is one of the few that have been approved for commercial use.
