More than half of a group of severely ill COVID-19 patients improved after receiving an experimental antiviral drug, although there is no way to know the odds of that happening without the drug, because there was no comparison group, doctors said on Friday.
The results published in the New England Journal of Medicine are the first in COVID-19 patients for remdesivir.
The Gilead Sciences drug has shown promise against other coronaviruses in the past and in lab tests against the one causing COVID-19, which has claimed more than 100,000 lives.

No drugs have been approved for treating the disease. At least five large studies are testing remdesivir, and the company also has given it to more than 1,700 patients on a case-by-case emergency basis.
Friday’s results are on 53 of those patients, ages 23 to 82, hospitalized in the US, Europe, Canada and Japan. Thirty-four of them were sick enough to require breathing machines.
All were given the drug intravenously for 10 days or as long as they tolerated it.
After 18 days on average, 36 patients, or 68 percent, needed less oxygen or breathing machine support.
Eight others worsened. Seven patients died, nearly all of them older than 70.
The 13 percent mortality rate is lower than seen in some other reports, but no true comparisons can be made without a study rigorously testing the drug in similar groups of patients, the authors said.
A dozen patients had serious problems, but it was not clear whether they were from the drug or their disease. Those included septic shock and trouble with kidneys and other organs. Four discontinued treatment because of health problems they developed.
“It looks encouraging,” said Elizabeth Hohmann, an infectious disease specialist at Massachusetts General Hospital who is helping lead one of the studies testing the drug.
The problems that occurred were not unexpected given the disease, she said.
Derek Angus, critical care chief at the University of Pittsburgh Medical Center who was not involved with the research, said the recovery rate is good, but “there is no way of knowing from this series if remdesivir was helpful.”
“We cannot draw definitive conclusions from these data, but the observations from this group of hospitalized patients who received remdesivir are hopeful,” said lead author Jonathan Grein, director of hospital epidemiology at Cedars-Sinai Medical Center in Los Angeles, in a statement from Gilead.
The Foster City, California-based company provided the medication and also helped analyze the results.
Results from more rigorous studies are expected by the end of this month.

‘NO SECURITY RISK’: The Railway Bureau reassured the public that the technicians’ activities were limited to technical guidance and did not involve sensitive systems The Railway Bureau yesterday said it had invited eight Chinese technicians to assist with an airport MRT construction project. The bureau issued the confirmation after an Internet user said Chinese nationals had entered the construction zone of Taiwan Taoyuan International Airport’s Terminal 3 project. They asked why “individuals from an enemy state” were allowed access to such a major national infrastructure project, which raised serious concerns over Taiwan’s industrial safety, sensitive systems and information security. The bureau’s Northern Region Engineering Branch Office said subcontractor Taiwan Handle Industrial Co (台灣手把工業) of the Taoyuan airport MRT’s “Contract No. CU05 Project A14 Station Civil, MEP &
A US uncrewed surface vessel (USV) encountered multiple Chinese warships during an autonomous transit of the Taiwan Strait, US defense company Seasats said in a statement on Wednesday. Seasats announced that a Lightfish USV had completed the first autonomous transit of the Taiwan Strait. Over five days, the USV traversed the entire length of the Strait while constantly monitoring surface vessel traffic, the company said. The Lightfish encountered multiple Chinese warships, one of which was a Chinese People’s Liberation Army Navy (PLAN) Type 056 corvette, it said. The Chinese vessels were operating “well within Taiwan’s exclusive economic zone without transmitting their identity via the
‘BOOMING’: ’ The number of partners we have here is incredible. You can see from their stock prices. They’re doing so well, they’re so happy,’ Jensen Huang said Nvidia Corp’s spending in Taiwan has ballooned to about US$150 billion a year, 10 times the US$10 billion to US$15 billion the company spent five years ago, Nvidia chief executive officer Jensen Huang (黃仁勳) said yesterday, suggesting Taiwan’s strategic importance in the global artificial intelligence (AI) supply chain. “Taiwan is the epicenter of the AI revolution. This is where the chips come, packaging comes. This is where the systems are made. This is where AI supercomputers were created,” Huang said at a meeting for the company’s employees in Beitou-Shilin Technology Park (北投士林科技園區) in Taipei, the planned site of Nvidia’s Taipei headquarters. “Taiwan
GREATER REACH? Auto parts and wood products would face tariffs of up to 15%, matching those targeting the EU, Japan and South Korea, Vice Premier said The US has announced that preferential tariff treatment for Taiwan’s non-semiconductor Section 232 goods would take effect retroactively from May 1, the Executive Yuan said yesterday. The US government yesterday posted a notice on the Federal Register’s public inspection Web site previewing tariff concessions for Taiwan under a memorandum of understanding (MOU) on Taiwan-US investment after two months of negotiations. The MOU signed on Jan. 15 stipulated three major preferential tariff arrangements: a 15 percent “reciprocal” tariff rate for Taiwan without stacking most-favored nation (MFN) rates; preferential Section 232 treatment for semiconductors and related products; and preferential Section 232 treatment for non-semiconductor
