(ECNS) -- A Chinese-American scientist has developed a drug injected into the muscle that can provide up to three months of protection against contracting HIV, and Hong Kong University hopes to cooperate with the team on clinical trials, Hong Kong-based Ming Pao said Thursday.

David Ho, a virologist at the Aaron Diamond AIDS Research Center in the United States, and his team have tested the drug on macaque monkeys, which can protect them from repeated intra-rectal infections of the deadly SHIV, a hybrid of the human and monkey AIDS virus.

The efficacy and safety of the drug have not been tested in humans, but Ho said the drug may be maintained at an adequate level for about three or four months.

The study has been published in the US journal Science.

The team plans to recruit 175 volunteers this year in the US, South Africa, Brazil and other places, the newspaper said, and they will carry out group tests in Beijing and Africa next year.

Chen Zhiwei, director of the AIDS Institute at Hong Kong University, said he will talk to Dr. Ho and his team about the clinical trials.

An official from the Hospital Authority of Hong Kong said Hong Kong intends to introduce the drug in the future.

A total of 559 new cases of HIV infections were reported in Hong Kong in 2013, the highest annual figure since Hong Kong's first case was diagnosed in 1984, according to official data.
