Biotech Company Struggling to Convince Doctors to Treat Burns with Pineapples
The story of Nasdaq-listed MediWound began with a German doctor, who searched for a way to treat the wounds of Wehrmacht soldiers stationed in North Africa

Founded in 2001 in Yavne, 18 miles south of Tel Aviv, MediWound develops, manufactures and commercializes treatments for severe burns and chronic wounds. The company’s flagship product is a pineapple enzyme-based treatment used for the removal of dead tissue from burn wounds called NexoBrid.
The gel preparation kit is compiled of two vials, one containing enzymes from powdered pineapple tree trunks, the other containing a water-based gel. The two are designed to be combined just before application on the skin. The gel is effective in removing only the dead tissue, possibly minimizing the need for surgical procedures.MediWound CEO Gal Cohen narrates a picturesque odyssey that led to the solution’s development. It began when German military doctor called Jerry Klein who was stationed in North Africa in World War Two. Dr. Klein searched for an effective, non-surgical way to treat the multitudes of burn wounds he encountered on the frontlines, before being captured by allied forces. A prisoner of war, Dr. Klein fell in love with a U.S. military nurse and followed her to the U.S. when the war ended. In the U.S. Dr. Klein met an American doctor, and the two began collaborating in the research of the medicinal properties of pineapple enzymes when applied to burns. The research evolved throughout the 1960s and 1970s, but the two were unable to isolate and control the levels of enzymes well enough to assure a consistent, marketable medication can be produced. Israeli plastic surgeon Lior Rosenberg took on Mr. Klein’s research after meeting him at a conference in Switzerland in the 1980s. For over two decades Mr. Rosenberg researched and experimented with pineapple enzyme-based treatments. At one time the head of the department of plastic surgery at Soroka University Medical Center in Israel’s southern city Be’er Sheva in Israel’s south, Mr. Rosenberg founded MediWound in 2001. “It took us 12 years from the moment we founded the company to receive marketing approval,” Gal Cohen, Mediwound CEO said in an interview with Calcalist Tuesday. NexoBrid was approved for marketing in Europe in 2012 and Israel in 2013.
“Evidenced-based clinical studies and growing experience reported by numerous experts treating patients in routine and mass casualty events demonstrate that NexoBrid will play a major role in the future of burn care,” said Albert Wu, Chief Executive Officer of Holy Stone.
In addition to Europe and South America, NexoBrid is also marketed in Japan, South Korea, and India.MediWound still awaits FDA approval. The company expects to begin a U.S. Phase III clinical trial and a pediatric Phase III study next year. All of NexoBrid U.S. research and registration process is funded by federal agency Biomedical Advanced Research and Development Authority (BARDA). In July, BARDA increased the funding for MediWound by $32 million, for a total of $56 million. In 2014 the company started trading on Nasdaq. In its March 2014 IPO, the company was traded at a price of $14 per share, with a market value of $265 million. Today it is traded for $5 per share, with a market value of $130 million. The company has raised $170 million to date, $100 million of which were in public offering. In September, the company raised $22 million for a stage three trial for a second product, ExcharEx, used to treat chronic and severe wounds. The stage three trial is set to take place next year in the U.S. Like NexoBrid, ExcharEx is also based on patented enzyme technology. Since NexoBrid was approved for marketing in Europe in 2012, Mediwound saw limited revenues. In the first half of 2017, the company reported $1.2 Million in revenues and had an operational loss of $7.4 million. This year, Mediwound sold about 5000 kits of NexoBrid, valued at a few hundred dollars each. The company’s revenues in 2015 and 2016 amounted only to several hundred thousand, causing an operational loss of $22 million in 2015 and $19 million in 2016. Mr. Cohen suggests that the main challenges NexoBrid is facing are the slow pace in which treatment protocols get changed, and the bureaucracy involved in obtaining insurance coverage for the drug. Still, he said, there is no surgical capacity to treat burn victims from multiple casualty incidents, not in Israel or anywhere else in the world, which should ultimately spell success for MediWound. Oppenheimer & Co Inc.’s biotech analyst Akiva Felt agrees. “NexoBrid is well positioned to gain a substantial share of the burn treatment market, due to its many advantages and its impressive clinical effectiveness,” he said.
