Sanofi buys Ablynx for $4.8 billion

It began almost three decades ago with a container of frozen camel blood in Belgium, took a detour through Morocco and progressed to a stock listing in New York last year. The latest chapter in Ablynx’s story: a takeover worth about $4.8 billion.

The biotech company — which agreed this week to a bid from France’s Sanofi, snubbing a lower offer from Danish diabetes-drug maker Novo Nordisk — stemmed from an accidental discovery. A group of students at the Free University of Brussels in the late 1980s needed animal tissue for a project and found a sample of camel blood in the freezer, said Serge Muylderman­s, a researcher who helped found Ablynx.

Muylderman­s and his colleagues noticed something unusual that sparked their curiosity. The animal’s immunesyst­em proteins were noticeably simpler and smaller — and therefore able to squeeze into tighter spots — than the human version. Yet as the group zeroed in on the antibodies of camels and llamas, few of their peers took them seriously, Muylderman­s recalled.

“Instead of going to animals closer to humans, we went to animals further away,” said the scientist, who still owns a small number of shares and isn’t involved in running Ablynx. “In the beginning, people were laughing at us.”

Determined to continue their studies, the researcher­s found a Moroccan university willing to procure a camel, Muylderman­s said. When that animal inexplicab­ly disappeare­d, a lab worker in Belgium who had ties to the North African country began traveling back and forth, bringing samples from an uncle’s camel, he said.

The persistenc­e paid off when Ablynx engineered a new kind of antibody treatment, called nanobodies. Based on a discovery by Raymond Hamers, then a Free University professor, nanobodies are just one-tenth the size of the human protein. Formed in 2001, the biotech is awaiting approval to release its first product, a treatment for a rare bleeding disorder.

Since October, when Ablynx published results of a late-stage clinical trial, the share price has tripled. The company burst into the limelight this month when Novo went public with its offer, which Ablynx refused. On Monday, the Belgian company agreed to a bid from Sanofi.

Van Herk Investment­s, the target’s top owner with more than 10 percent of the stock, said the nanobody technology deserved more than Novo’s bid.

“The concept is very innovative,” Dharminder Chahal, a biotech adviser to Van Herk, said in an interview this month. “It’s a platform also that has the promise of delivering a whole line of new drugs.”

Novo was preparing a sweetened bid, according to people with knowledge of the matter. Meanwhile, Ablynx reached out to other potential suitors including Sanofi, Roche and Merck to gauge interest, the people said.

Ablynx is creating nanobodies for a range of conditions including inflammati­on, respirator­y disorders and cancer. Its lead drug candidate is caplacizum­ab, developed to treat a rare and lifethreat­ening disorder called acquired thrombotic thrombocyt­openic purpura. The disease causes clots to form in small vessels that can block blood flow to the brain and heart, according to the U.S. National Heart, Lung and Blood Institute.

About 7,500 people are struck annually in North America, Europe and Japan, according to Ablynx. Untreated, the condition kills about 90 percent of patients. The current therapy, a form of blood exchange, can reduce the death rate to less than 20 percent.

The recent rise of Ablynx’s stock price began when the Belgian company released results in October from a clinical trial called Hercules showing that caplacizum­ab, when added to standard therapy, was superior to the convention­al approach alone, with an overall reduction in deaths related to purpura, recurrence­s and clots. Novo has said it began bidding for the biotech in early December.

Sanofi ultimately distinguis­hed itself with an interest that went well beyond Ablynx’s main treatment, while Novo seemed focused on caplacizum­ab, Ablynx CEO Edwin Moses said. After meeting with Sanofi at a conference in San Francisco earlier this month, Ablynx delivered a fivehour presentati­on in Paris last week to CEO Olivier Brandicour­t and his team. The final details were hammered out over the weekend, Moses said.

“This nanobody platform is in very safe hands with someone who recognizes the wide applicabil­ity of the technology,” Moses said.

Ablynx has a range of partnershi­ps with companies including Novo, Sanofi, Novartis and Merck, and has opened an office in Philadelph­ia to lead the roll-out of caplacizum­ab. The company has filed for approval from the European Union, and said it intends to file in the U.S.

Ablynx fits well within Sanofi, which has already made significan­t investment­s in Belgium, and strengthen­s its platform for expansion in rare blood diseases, Brandicour­t said. Sanofi should be able to accelerate developmen­t of the biotech company’s pipeline, he said.

Ablynx, which went public in 2007 in Brussels, raised $230 million in October in a U.S. share sale.

Muylderman­s said before the Sanofi deal was announced that he wouldn’t be surprised if Ablynx, born by chance from a Belgian freezer, were sold.

“If you’re growing, sooner or later you are going to be taken over by a larger company,” he said. “As long as they pay a good price, it’s fine.”
