HOW THE DRUG WORKS听
The drug鈥檚 mechanism of action is to insert itself in the COVID-19 virus, said Dr. Mary Ann Galang-Escalona, country medical lead, MSD in the Philippines, in a Tuesday webinar. MSD (known as Merck in the United States and Canada) and Miami-based Ridgeback Biotherapeutics developed the drug, which entered Phase 3 clinical trials this June.听听
鈥淚f you鈥檙e given it early in the course of the disease,鈥 she said, 鈥渋t can cause a viral error catastrophe. It鈥檚 a phenomenon where the drug inserts itself into the body of the virus. What happens is that all copies of that virus become defective, which means the virus will not cause further severity of the disease for that person.鈥澨听
The difference between the pill and a vaccine, Dr. Galang-Escalona explained, is that the pill itself will not trigger an antibody response. 鈥淚t aims to address current infection, but not prevent a future one,鈥 she said.听听听
Those who participate听in听the clinical trial will be given the trial drug or a placebo to take by mouth every 12 hours for five days.听听听
QMMC鈥檚 Dr. Joel M. Santiaguel said volunteers will be monitored via site visits, home visits, and virtual visits for up to seven months.听鈥淲e鈥檒l be getting blood for testing, performing RT-PCR (real time reverse transcriptase-polymerase chain reaction), and interviewing patients for safety issues,鈥 he said.听听听
鈥淧atients can choose to discontinue the trial at any time for any reason,鈥 added Dr. Virginia S. Delos Reyes of the Lung Center, which started its trial on May 17 and has already completed the trial on 15 patients.听听
Worldwide, the clinical trial has already reached 50% of its target number of participants. The panelists hope that the drug will be rolled out within the year.听听
鈥淚t will depend on the interim analysis we are submitting to the Food and Drug Administration for the US鈥檚 Emergency Use Authorization,鈥 Dr. Galang-Escalona said. 鈥淲e are hoping for a merry Christmas.鈥澨听
