SAN DIEGO (KGTV) — The Department of Defense has awarded a San Diego biotech company up to million to help develop a next-generation drug to fight COVID-19.Sorrento Therapeutics calls the drug a “rapid countermeasure” against the disease, one that might serve as a vaccine substitute in certain populations or a critical stopgap tool if the virus mutates.“With this, we have a new platform potentially that can respond very quickly to any type of emerging threat,” said CEO Dr. Henry Ji.Sorrento is trying to become the first company to develop an approved DNA-encoded monoclonal antibody treatment. The approach is similar to the experimental monoclonal antibody treatment used on President Trump, but Sorrento’s concept is a more advanced version that offers several benefits.Sorrento’s drug is designed to be used as either a treatment in infected patients or a fast-forming layer of defense in healthy people. The company said its solution should be cheaper and easier to deploy than existing monoclonal antibodies, while offering vaccine-like protective effects that last for several months rather than just two or three weeks.Antibodies are one of the body’s key defense mechanisms. They seek out pathogens and bind to them, marking the invader for destruction like ground troops marking an enemy base for an airstrike. In some cases, antibodies can even neutralize an invader themselves by blocking its method of entry into cells.Monoclonal antibodies are antibodies designed by scientists to neutralize a pathogen. They are hand-picked, genetically modified super antibodies that are cloned in labs.However, the process of growing these super soldiers in the lab is difficult, transporting them requires a cold chain, and as a result, monoclonal antibodies are among the most expensive drugs in the world.Instead of giving people an infusion of pre-made antibodies, Sorrento’s idea is to give people a shot of DNA that instructs some of their cells to churn out perfectly pre-designed antibodies.“It's much easier to make enough DNA to treat a large number of people than it is to make enough protein to treat a large number of people. That’s just a fact about manufacturing,” said Dr. Robert Allen, Sorrento’s chief scientific officer on the project.Dr. Allen said the company is hopeful the drug will induce cells to make protective antibodies for six months or more.This DNA approach to an antibody treatment has never been approved for any disease but other companies are working on their own versions of it. Another biotech with ties to San Diego, Inovio Pharmaceuticals, became the first company to test this approach in humans in 2019 for a drug targeting the Zika virus.Sorrento’s approach is similar to the way DNA vaccines work, but it cuts out intermediary steps and jumpstarts the production of antibodies, rather than leaving the production of antibodies up to the body’s immune system. The result is that protective antibodies can start circulating in days after injection rather than weeks, the company said.“What this is capable of doing is it bypasses the need for the immune system,” said Dr. Mark Brunswick, Sorrento’s senior vice president for regulatory affairs.The drug is unlikely to replace a vaccine in most situations because vaccines can produce other defense mechanisms like T-cells that work in conjunction with antibodies. But the drug might work better than a vaccine for the elderly and others with weakened immune systems who are unable to produce a robust number of antibodies on their own, Brunswick said.Still, the company still has a lot of pre-clinical work and testing to go. Sorrento is hoping to have the drug ready for human trials in four to six months.By then, vaccines from Pfizer and Moderna will likely be widely available, but Dr. Ji said the world needs to prepare for the possibility this virus will mutate.“When you vaccinate hundreds of millions, potentially billions of people, the virus is under tremendous evolution pressure,” he said. “It will escape. It’s guaranteed that the virus is going to mutate and escape all of the vaccines we’re trying to create.”If it does, he said Sorrento will be ready to rapidly deploy its DNA-based countermeasure. 4223

SAN DIEGO (KGTV) - The International Olympic Committee and Japanese government made an historic announcement Tuesday to postpone the 2020 summer Olympic games in Tokyo due to the coronavirus.Tuesday, Japanese Prime Minister Shinzo Abe confirmed on Twitter that the Tokyo Olympic and Paralympic games have been delayed until no later than summer 2021.The announcement left several San Diegan Olympic hopefuls dashed of any immediate Olympic dreams."It's kind of hard to wrap your head around it because you have been training so long for this one moment," Allison Halverson said back in Februaray.Her tone changed Tuesday."I was kind of like, 'Ok. That's good to know.' Now I can kind of refocus and figure out how to train for that," Halverson said.Swimmer Michael Chadwick says the lack of open pools is sidelining any training, making competition right now even less of a possibility."Too much has happened too quickly for us to really understand what the ramifications of it all are," Chadwick said. "We as athletes cannot expect to make a push right now, physically, it's just impossible. Especially with not having a pool open."A new date for the postponed games has not been announced. 1199

SAN DIEGO (KGTV) - Supporters of the newly passed California Prop 17, which restores the right to vote to felons on parole, believe the vote outcome may help improve public safety.For the first time in some three decades, Mancy Thompson, 56, was allowed to cast a vote in a presidential election, recently sending in his mail-in ballot from his La Mesa home."Elated. I felt like,'Yes!'" said Thompson.For decades, the answer had been "no."In 1987, high on cocaine and heroin, the active-duty Marine shot and killed a bystander during a bar fight in Oceanside. After pleading guilty and serving more than 23 years in prison, he was released on parole in 2011.He graduated from a reentry program at the local nonprofit Second Chance, and has held down jobs ever since, including positions at the nonprofit. He was on parole for seven years and not legally allowed to vote."If I am disenfranchised, I'm no longer connected. I don't have value to myself, family or community, because they don't have to listen to you," said Thompson.When he got off parole, his right to vote was restored. That right that will now be granted to some 50,000 state parolees, thanks to the passage of Prop 17.Thompson says it can help remove the stigma of the past."Now I have a right to be heard and participle in the democratic process. It's huge," said Thompson.Prop 17 supporters point to a recent parole commission report that found felons with voting rights were less likely to commit future crimes. Opponents say the right to vote shouldn't be granted until parolees have proven they're rehabilitated and allowing the parolees to vote denies justice to victims.Prop 17 passed with an unofficial 59% of the vote."If we want to help them reengage their community and be better versions of themselves ... part of that integration is being able to vote," said Thompson. 1856

  

SAN DIEGO (KGTV) - Surveillance video captures a burglar on the move inside a popular restaurant in Mira Mesa, and his crimes may be escalating.Inside the kitchen of T.P. Bahn Bao on Camino Ruiz, the staff is busy making steamed Vietnamese buns, days after an unappetizing discovery. "Scared, anxiety, disbelief," said Travis Nguyen, who owns the restaurant.When she got in on Thursday morning, she found loose change all over and the drawer of the cash register gone. The surveillance video revealed what happened. Just before 3 a.m., a figure is seen crouched low, shining a flashlight into the restaurant. After a few moments, the man pries open the door and walks in."It appeared he used a homemade tool to break the panic bar. It took him only a few seconds to get in," said Lon Holliday of Convoy Street Locksmith, the company that repaired the door.In the video, the man quickly heads to the cash register, removes the drawer and about 0 in cash."He knows what he's doing. I think he's done this before," said Nguyen. After the thief is done in the front - and with a loud security alarm going off - the intruder heads towards the kitchen, where he looks around. He then goes into the walk-in cooler. He apparently doesn't like what he sees and takes off."He's in and out of the restaurant in under two minutes. He's quick," said Nguyen. It's an elusive quality residents in the a nearby neighborhood are familiar with. Amid of a rash of porch and package thefts, one homeowner sent 10news video of a man on a bike she saw stealing a car jack from a porch two weeks ago. The man does resemble the intruder. If it's the same man who broke into the restaurant, he's getting bolder."You never know what he can do. Not only stealing stuff, he might be so desperate he might hurt people, too. Needs to be caught," said Nguyen.Anyone with information on the case is asked to call San Diego Police at 619-531-2000. 1926

  

SAN DIEGO (KGTV) — The County of San Diego is preparing to step up enforcement efforts on businesses flouting public health orders, taking the reins from local agencies like the San Diego Police Department that have virtually stopped issuing tickets to violators.Despite thousands of complaints about violations to the county's 211 hotline, data from the San Diego Police Department shows the agency has issued 168 citations for health order violations since the pandemic shutdowns began. Ninety-one percent of those citations came in April.Since then, citations decreased to 12 in May, 3 in June, and zero in July. Violating the public health order is a misdemeanor punishable by up to a ,000 fine or six months in jail.“As these health orders continue to change it makes it really difficult for law enforcement,” said SDPD Lt. Shawn Takeuchi.Since April, 211 received 9,382 complaints about public health order violations. During that span the county’s two largest law enforcement agencies, the Sheriff’s Department and SDPD, issued 312 citations combined.Lt. Takeuchi said you have to look back at the public health orders over time: in March, beaches and parks were closed and non-essential businesses were shut down. By April, it was easy to spot violators and expect they knew the rules.“It was a real black and white area,” he said.But then in late May, restrictions eased up, businesses started reopening, and Takeuchi said the regulations were less obvious. The mask ordinance, for example, only applies when an individual is within six feet of a non-household member. Determining whether groups of people walking the street are members of a household is highly impractical, he said.“When the county rules started to morph, we needed to understand them and we needed to make sure people understood them. So we always undertook an effort to educate first,” he said.Since then, the public health orders have been modified several times -- at least three times in July alone -- and Lt. Takeuchi said the department has had to embark on a new education campaign each time.“You've seen the San Diego Police Department really back off on enforcement because we think that the County Health Officer is really in a better position to ensure compliance of what they've deemed the egregious or the bad actors,” he said.This week, the county announced it would take on a more central role with enforcement, bringing on staff to more rapidly investigate cases like the one at The Gym in Pacific Beach, and opening a new compliance hotline.The new hotline and email system will replace the existing 211, so tipsters can speak directly with a county employee. 2664
