We have a wonderful relationship with PM Modi, India: US

May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.

Paris, Apr 24: The worldwide death toll from the coronavirus pandemic crossed 190,000 on Friday, with nearly two-thirds of the fatalities in Europe, according to an AFP tally compiled from official sources at 0740 GMT.

A total of 190,089 people have died and 2,698,733 been infected since the virus emerged in China in December. The hardest hit continent is Europe, with 116,221 deaths and 1,296,248 cases.

The country with the most deaths is the United States with 49,963, followed by Italy with 25,549, Spain with 22,157, France with 21,856 and Britain 18,738.

New Delhi, Feb 1: Activist Sharjeel Imam's mobile phone and laptop along with some anti-CAA posters have been seized from his house in Bihar's Jehanabad and rented flat in Vasant Kunj, police said on Friday.

Imam was arrested by the Delhi Police's Crime Branch from Jehanabad in a sedition case and he is being questioned by police for his alleged inflammatory speeches in Aligarh and at the Jamia Millia Islamia University here.

During investigation, a laptop and a desktop belonging to Imam were recovered from his rented flat at Vasant Kunj, Deputy Commissioner of Police (Crime) Rajesh Deo said.

His mobile phone was recovered from his house at his native place in Jehanabad's Kako area on the instance of his brother, he said.

Imam had prepared anti-CAA and anti-NRC pamphlets with "misleading and intimidating facts" and then distributed them in various mosques, the copy of which have been recovered, police said.

The shop from where he made photocopies of the pamphlets has also been identified, they added.

Imam was arrested on Tuesday. He was brought to Delhi on Wednesday and produced at the residence of Chief Metropolitan Magistrate Purushottam Pathak in the evening amid tight security after which police were granted his five-day custody.

The PhD scholar at the Jawaharlal Nehru University's Centre for Historical Studies has been booked for sedition and other charges in several states after videos of his alleged inflammatory speeches, made during protests against the Citizenship (Amendment) Act (CAA), were circulated on the social media.

An FIR was registered against Imam by the Delhi Police on January 25 under IPC sections 124A (sedition) and 153A (promoting or attempting to promote disharmony or feelings of enmity on grounds of religion, race, place of birth, residence, language, caste or community or any other ground whatsoever) among others.
