Novartis sickle-cell drug gets U.S. FDA approval
By John Miller and Carl O'Donnell (Reuters) - Novartis AG on Friday won U.S. approval for its experimental sickle cell disease drug, Adakveo, making it the first of several proposed new therapies designed to offer lasting relief for patients with the debilitating blood disease to get U.S. regulatory clearance

The biologic drug, also known as crizanlizumab, was shown in trials in its high-dose formula to cut sickle cell pain crises nearly by half to 1.63 incidents annually from 2.98 in those getting a placebo. The Food and Drug Administration's approval came nearly two months ahead of its due date for a decision in January.
Novartis has forecast that the drug's annual sales will top $1 billion (£781.49 million), much of which will likely come from U.S. government payers such as Medicare and Medicaid.
The drug is the first to offer patients with sickle cell disease targetted relief from pain crises, a common symptom of sickle cell disease, which often also causes swelling, infections, and vision problems. Current treatments, which include blood transfusions, drugs that increase haemoglobin, and pain medicines, only alleviate symptoms as they arise.
Novartis' drug may soon face competition from Voxelotor, a once daily pill developed by Global Blood Therapeutics Inc
Other potential cures for the disease that would alter genetic mutations responsible for blood cell sickling are also undergoing clinical trials run by drugmakers including Bluebird Bio Inc
About 100,000 people in the United States, most of African descent, suffer from the disease in which their red blood cells are sickle-shaped, leading to episodes of intense pain, infections and deadly strokes.

By Robin Emmott and John Irish | BRUSSELS/PARIS BRUSSELS/PARIS France and Germany will agree to a U.S. plan for NATO to take a bigger role in the fight against Islamic militants at a meeting with President Donald Trump on Thursday, but insist the move is purely symbolic, four senior European diplomats said.The decision to allow the North Atlantic Treaty Organization to join the coalition against Islamic State in Syria and Iraq follows weeks of pressure on the two allies, who are wary of NATO confronting Russia in Syria and of alienating Arab countries who see NATO as pushing a pro-Western agenda."NATO as an institution will join the coalition," said one senior diplomat involved in the discussions. "The question is whether this just a symbolic gesture to the United States
BEIJING Chinese President Xi Jinping on Wednesday called for greater efforts to make the country's navy a world class one, strong in operations on, below and above the surface, as it steps up its ability to project power far from its shores.China's navy has taken an increasingly prominent role in recent months, with a rising star admiral taking command, its first aircraft carrier sailing around self-ruled Taiwan and a new aircraft carrier launched last month.With President Donald Trump promising a US shipbuilding spree and unnerving Beijing with his unpredictable approach on hot button issues including Taiwan and the South and East China Seas, China is pushing to narrow the gap with the U.S. Navy.Inspecting navy headquarters, Xi said the navy should "aim for the top ranks in the world", the Defence Ministry said in a statement about his visit."Building a strong and modern navy is an important mark of a top ranking global military," the ministry paraphrased Xi as saying.
