Los Angeles, California

Los Angeles, the "City of Angels" is California's largest city and is second only to New York in population. It is known for the Hollywood entertainment industry, mild climate, bumper-to-bumper traffic, ethnic diversity and considerable leisure and outdoor opportunities. When it comes to health care, this sprawling metropolis has more than 25 hospitals with scores more in the surrounding Los Angeles county. So, there is no shortage facilities for Angelenos to receive general medical services, emergency and acute care, and specialty health care.

Below are some of the best hospitals in the city of Los Angeles, according to U.S. News and World Report. The media company's Best Hospitals rankings helps consumers make decisions about where to find inpatient hospital care in their community and beyond. Los Angeles clinical trials can be found at almost all of them.

UCLA Health

For more than 30 years, the UCLA Health system has been ranked among the country's best in U.S News and World Report's annual review. Within the LA city limits, three UCLA hospitals reside on the UCLA Health main campus in the Westwood section of the city. Ronald Reagan UCLA Medical Center, UCLA Mattel Children's Hospital and UCLA Resnick Neuropsychiatric Hospital:

Ronald Reagan UCLA Medical Center

With more than 1,500 doctors on staff, Ronald Reagan UCLA Medical Center cares for more than 300,000 people a year from greater Los Angeles, California and around the world. It is a general medical and surgical hospital, level one trauma center and teaching facility. US News and World Report has ranked it as the 4th best hospital in the U.S. and first on the West Coast.

WELCOME TO SANTA MONICA CLINICAL TRIALS

Santa Monica Clinical Trials is a private clinical research site located in Los Angeles, California. Our Investigators have over 20 years of experience and are engaged in numerous phase II-IV clinical research trials, including drug and medical device studies. Participation does not require proof of medical insurance. All trials are conducted under FDA guidance and regulations.

If you or a loved one suffers from one of these disorders, take the next step and contact a member of our study team today! No medical insurance needed. Compensation for time & travel may be available upon inquiry.

Current trials, prader-willi syndrome.

Prader-Willi Syndrome (PWS) is a congenital syndrome that affects many systems of the body. Common early signs of PWS include muscle weakness, feeding difficulties, and behavioral disturbances. Patients may also experience excessive daytime sleepiness (EDS), making it difficult to perform everyday activities and negatively affecting their mood. The purpose of this study is to evaluate the efficacy and safety of the study medication on daytime sleepiness in those with Prader-Willi Syndrome.

Children at School

Narcolepsy is a chronic neurological disorder that affects the brain's ability to regulate sleep-wake cycles. Those with narcolepsy experience excessive daytime sleepiness despite feeling well-rested upon waking. Individuals might have frequent, uncontrollable bouts of sleep. Depending on the type of narcolepsy, symptoms may also include sudden muscle weakness causing patients to go limp. This study will explore the efficacy and safety of an oral study medication in promoting wakefulness in those with narcolepsy type 1 (NT1) or narcolepsy type 2 (NT2).

Sleeping in Green Sheets

IDIOPATHIC HYPERSOMNIA

Idiopathic hypersomnia (IH) is a rare neurological disorder which is characterized primarily by excessive sleep and excessive daytime sleepiness. This study will look at safety and efficacy of the oral investigational drug in promoting wakefulness for those with idiopathic hypersomnia.

Sleeping with Eye Mask

SLEEP APNEA

Obstructive Sleep Apnea (OSA) is a common and serious sleep disorder in which breathing is repeatedly interrupted during sleep. OSA occurs when the airway collapses as you breathe in. This can cause breathing to be paused from several seconds to over a minute. 

While many people use continuous positive airway pressure (CPAP) machines to manage their OSA, these systems can be cumbersome and awkward for some. The LunAIRo study involves an investigational oral medication for people who have OSA. The investigational medication will be taken daily at bedtime. 

research studies los angeles

SLEEP DISTURBANCES IN INDIVIDUALS WITH AUTISM SPECTRUM DISORDER

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that is associated with persistent deficits in social communication, restricted/repetitive behaviors, among other symptoms. Sleep disruption in individuals with ASD is higher than in healthy controls with a documented prevalence of up to 80%. The purpose of this study is to evaluate the effectiveness and safety of the study medication on sleep in individuals with autism spectrum disorder.

Kids in Preschool

MOTION SICKNESS

Motion sickness is a common condition affecting about 30% of the population. Common symptoms of motion sickness include nausea, vomiting, stomach awareness, pallor, headache, sweating, dizziness, a sensation of warmth and drowsiness. The purpose of the study is to evaluate the effectiveness of an investigational drug on symptoms associated with motion sickness and to assess the safety of the investigational drug.

Ocean

DELAYED SLEEP-WAKE PHASE DISORDER

Delayed sleep–wake phase disorder (DSWPD) is a chronic dysregulation of a person's circadian rhythm (biological clock), compared to those of the general population and societal norms.  People with DSWPD generally fall asleep some hours after midnight and have difficulty waking up in the morning. However, they find it very difficult to wake up in time for a typical school or work day. If they are allowed to follow their own schedules, e.g. sleeping from 4:00 am to 1:00 pm, their sleep is improved and they may not experience excessive daytime sleepiness. The purpose of this study is to evaluate the efficacy and safety of an investigational medication compared to placebo for this condition.

California Paid Clinical Trials

Match to clinical trials, popular cities.

Kaiser Permanente houses over 6,000 physicians in southern California and it is also one of the largest research centers on the state. On its clinical trial division, Kaiser Permanente conducts clinical trials of almost every specialty funded by pharmaceutical companies, government, and foundations.

The Cedars-Sinai Medical Center located in Los Angeles is one of the largest research centers owned and operated by a private hospital in the United States. Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.

There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.

Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.

In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.

Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future. The following lists of trials are broken down by condition, and to find a specific clinical trial in your area click through to clinicaltrials.gov.

2024 Hanson-Thorell Family Research Awards Launch New Studies to Improve Alzheimer’s Disease and Sarcopenia Treatments

Home » 2024 Hanson-Thorell Family Research Awards Launch New Studies to Improve Alzheimer’s Disease and Sarcopenia Treatments

USC Leonard Davis School professors are launching studies to examine treatments and potential treatments for Alzheimer’s disease and sarcopenia.  As recipients of the 2024 Hanson-Thorell Family Research Awards, Assistant Professor Michelle Keller and Research Assistant Professor Hiroshi Kumagai each received $25,000 for one-year pilot projects aiming to improve how these two common age-related conditions might be treated and potentially lower the costs for doing so.

Keller’s study looks at new Alzheimer’s therapies and seeks to explore how doctors decide whether to prescribe them, which factors influence their decisions, and how patients from various backgrounds perceive the value and risks of these treatments.

Alzheimer’s disease is a growing health concern in the U.S., especially among older adults, with the number of affected individuals expected to nearly triple by 2050. New drugs like lecanemab offer hope by slowing disease progression, but they come with serious risks, including brain swelling and bleeding, and are very expensive. Doctors and patients must carefully weigh the benefits against these risks and costs.

“This decision-making is particularly complex for people from diverse racial and ethnic backgrounds, who may have different perspectives on the risks due to factors like health literacy, access to care, and trust in the medical system,” said Keller. “Findings from this pilot study will be used as the basis for a future proposal to the National Institutes of Health and I am so grateful to have received this award to jump-start my research in this important area.”

Keller’s goal is to understand how different health systems are using new Alzheimer’s drugs and to create better ways for doctors and patients to talk about the risks and benefits of these medications. She says the research could also hold policy implications by highlighting the challenges people face in getting treatment and how much it might cost both nationally and in individual states.

Kumagai’s proposal introduces a newly discovered mitochondrial protein protein called PUTZ, that may play a role in sarcopenia, or age-related muscle loss, a major but under-researched area in aging science. The study will also investigate whether blocking this protein could be a new way to treat the condition. Sarcopenia and related frailty lead to higher health risks and cost the U.S. healthcare system about $40 billion each year.

“This research could pave the way for new treatments that not only improve health outcomes but also reduce healthcare costs,” said Kumagai. “I am so appreciative of the Hanson-Thorell family’s generosity in allowing me to advance research in this area.”

Kumagai will also evaluate whether exercise can protect against the harmful effects of PUTZ and will test this by having young and older mice, with and without the PUTZ gene, exercise on a running wheel and then check their muscle size and strength.

“The hope is that these experiments will provide essential information that could lead to a bigger, long-term project focused on developing treatments that block PUTZ to help prevent frailty and muscle loss in aging,” said Kumagai.

The Hanson-Thorell Family Research Award recognizes the importance of innovative research and encourages young scientists to push the boundaries of their fields. The award, supported in part by Board of Councilors Chair Shari Thorell and her husband Bob, originated with funding from Shari’s father and former Board of Councilors Chairman Al Hanson.

New genetic research points to Wuhan animal market as origin of COVID pandemic, study says

Vehicles idle in an open warehouse surrounded by people in surgical masks.

  • Copy Link URL Copied!

A new analysis of genetic material gathered from a live-animal market in Wuhan in the early weeks of the COVID-19 pandemic strengthens the case that the outbreak originated there when the coronavirus jumped from infected animals to humans, scientists said.

The findings , reported the journal Cell, do not identify any specific infected animal that brought the SARS-CoV-2 virus to a Chinese city inhabited by more than 11 million people. Nor do they definitively prove that the Huanan Seafood Wholesale Market was Ground Zero for a pandemic that has resulted in more than 7 million deaths .

But the genetic evidence shows the market met the conditions necessary to spark an outbreak and makes it increasingly difficult to explain how the coronavirus could have emerged from a laboratory, a farm or even from another of the city’s four live-animal markets, the study authors said.

“It’s like if a gorilla virus emerged in San Diego and first hit people who worked at the San Diego Zoo and lived nearby, then spread later more widely,” said Michael Worobey , an evolutionary biologist at the University of Arizona who worked on the study. “It would not be difficult to reason that it very likely came from the gorillas at the zoo.”

The root cause of the pandemic has been hotly debated since its early days. Wuhan is home to a government laboratory where scientists study coronaviruses similar to SARS-CoV-2, a fact that prompted politicians , national security experts , late-night talk show hosts and many scientists — including Worobey — to question whether the virus had leaked from the lab.

Compelling though the argument may be, hard evidence to support the leak hypothesis has been lacking. Meanwhile, more information has come to light that has persuaded scientists with expertise in relevant fields that the virus that causes COVID-19 originated in animals, just like the viruses that cause SARS, MERS and influenza.

The new results continue that trend, said Dr. Dominic Dwyer , a member of the international task force that investigated the pandemic’s origins for the World Health Organization.

“You put all of these origin hypotheses on the table, and then some of them become stronger as you get evidence,” said Dwyer, a medical virologist at the University of Sydney and Westmead Hospital in Australia who wasn’t involved in the latest work. “This paper has more evidence that supports the animal origin through the Huanan market.”

Fresh look at earliest COVID cases points to live-animal market as most likely source

A close analysis of Wuhan’s earliest COVID-19 cases points to a live-animal market as the most likely source of the novel coronavirus, a study argues.

Nov. 18, 2021

The analysis published Thursday was based on genetic data gleaned from hundreds of samples gathered in and around the Huanan market collected by researchers from the Chinese Center for Disease Control and Prevention soon after the market was shut down on Jan. 1, 2020. The Chinese team detected the coronavirus in 74 of the environmental samples they tested, according to their report last year in the journal Nature.

Worobey and his colleagues dug deeper into that data. Using two distinct gene-sequencing techniques, they looked for pieces of SARS-CoV-2 as well as for DNA from animals and people.

Then they plotted what they found on a map of the sprawling market, allowing the team to reconstruct how a few initial infections could have ballooned into a global health emergency.

Among 585 samples gathered in early January 2020, the ones that contained the coronavirus were clustered in the southwestern section of the market. That happened to be the area where wild animals were held in cages for sale.

“The market covers a couple of acres, and this comes down to one corner of the market, and to a couple of stalls,” Dwyer said. “That fits with an animal origin. If it was coming from people wandering around the market, you’d find it everywhere.”

One market stall “stood out,” the study authors wrote. It had evidence of SARS-CoV-2 in multiple places: on at least one cart, on an iron container, on the ground, and on a machine used to remove hair and feathers. The researchers dubbed it “wildlife stall A.”

Another 60 samples were taken from the market’s drainage system at the end of January 2020. The researchers found genetic evidence of the coronavirus in four of them, including one in front of wildlife stall A.

That drain was still testing positive for SARS-CoV-2 in mid-February. So were two drains downstream from it that could have been contaminated by runoff from wildlife stall A, the researchers wrote.

New studies say Wuhan market is the only ‘plausible’ source of COVID-19 pandemic

Two new studies build on evidence that the coronavirus that causes COVID-19 jumped to humans in a Wuhan market, and did so twice.

July 26, 2022

The samples from the stall that contained the coronavirus also contained DNA from a variety of animals, including dogs, rabbits, hoary bamboo rats, Malayan porcupines and masked palm civets. The most abundant DNA was from raccoon dogs, and some was detected in a nearby garbage cart that also tested positive for the virus.

The closest-known relatives to SARS-CoV-2 that exist in the wild are coronaviruses that circulate in horseshoe bats in southern China, Laos and Vietnam and in pangolins from southern China. But no DNA from bats or pangolins turned up in any of the Huanan market samples.

Raccoon dogs, masked palm civets, hoary bamboo rats and Malayan porcupines have transmitted bat coronaviruses before , the study authors noted. Could they have done so in Wuhan, they wondered?

It is unclear whether bamboo rats or Malayan porcupines can be infected with SARS-CoV-2, the study authors wrote. There is no hard evidence that masked palm civets can catch the virus, but cell lines from the animals were susceptible in laboratory experiments .

Raccoon dogs, on the other hand, are known to catch and transmit SARS-CoV-2 . And they were the most abundant animal in wildlife stall A.

The researchers dug into the raccoon dog DNA to see if they could have come from southern China, where they might have crossed paths with bats. They couldn’t tell, but they were able to rule out a connection to raccoon dogs that lived on fur farms in northern China.

Worobey and his colleagues also studied non-SARS-CoV-2 animal viruses that were detected in wildlife stalls to see if they offered clues about where the infected animals had come from.

A kobuvirus that infected civets in the Huanan market was closely related to a virus detected in animals sold in Sichuan and Guangxi provinces, which are closer to the territory of horseshoe bats and pangolins. And a betacoronavirus that infected bamboo rats had a close relative on a bamboo rat farm in Guangxi, one of two southern provinces where market vendors were known to have sourced the animals.

“These findings suggest some movement of infected animals from southern China to Wuhan, a trade conduit that could have also led to the emergence of SARS-CoV-2,” the study authors wrote.

Nailing this down will require more sleuthing, including field work to collect samples from animals in China, said Florence Débarre , an evolutionary biologist at the French National Centre for Scientific Research in Paris and the study’s senior author. Worobey said he plans to continue this line of inquiry.

Dwyer praised the effort to determine where the animals in the market had come from — and by extension, how the virus could have gotten to the market.

Forty-one people with pneumonia-like symptoms have so far been diagnosed with the new virus in Wuhan, with one of the victims dying on January 8, 2020, the central Chinese city's health commission said on its website.

Opinion: I called for more research on the COVID ‘lab leak theory.’ Here’s what I found out

Contrary to conclusions by the Department of Energy and the FBI, the science on the pandemic’s origins stacks up in favor of a jump from animals to humans.

March 8, 2023

A second line of evidence also supports the hypothesis that the pandemic had a so-called zoonotic origin, scientists said.

Among the samples collected at the Huanan market on Jan. 1, 2020, the researchers were able to identify four nearly complete SARS-CoV-2 genomes. One of them was from so-called lineage A, and the other three were from the closely related lineage B.

The researchers weren’t able to tell whether those viruses were shed by animals or people, but the lineage A sample came from a stall where a worker sought medical attention in mid-December 2019. Although that was weeks before COVID-19 had been recognized as a disease, a report from the World Health Organization later described the worker as a suspected early patient.

Confirming the presence of both lineages in the market allowed the team to compare their genomes and work backward to figure out when the two strains diverged, and what their most recent common ancestor looked like. They came up with six candidates, some of them more plausible than others.

There was a 99% probability that one of the four most likely candidates was correct, and those four all had something important in common: They were “equivalent or identical” to the most recent common ancestor for the pandemic as a whole, said study leader Alexander Crits-Christoph , an independent computational microbiologist.

That’s what they would expect to find if the outbreak began at the Huanan market, the study authors said. In that scenario, an animal or animals infected with the virus arrived at the market in November or early December. The virus then spread among animals held in close quarters indoors, as well as to their human handlers. Those conditions would have given the virus the multiple chances it needed to establish itself in people and begin spreading among its new hosts in a densely populated city.

A timeline of COVID-19’s first weeks in Wuhan

A timeline of COVID-19’s early weeks in China, beginning with the emergence of the first patient on or around Nov. 18.

On the other hand, it’s getting more difficult to fit all of this evidence into a coherent story that has the coronavirus entering China via imported frozen food (as the Chinese government has claimed) or escaping from a virology lab with lax biosecurity protocols (as some members of the U.S. intelligence community have proposed), Dwyer said.

“We’ve had nothing added to support the lab leak or the frozen food theories,” he said. “It just continues to strengthen the animal and market hypothesis.”

Considering that the pandemic began in a city with a virology lab where scientists study coronaviruses, it makes sense to ask whether that’s more than a coincidence and to wonder whether incriminating evidence is being covered up, DéBarre said.

“Many of us were extremely open to this idea,” she said. “But then data have accumulated, and they all go in the same direction — they all point to the market.”

“In science you very rarely have final answers,” she added. “You say, ‘Given all the data we have, this looks like the most likely interpretation.’”
