Mayo Clinic's Center for Regenerative Biotherapeutics is collaborating with the biotech firm HepaTx on an experimental therapy to regenerate tissue in patients with late-stage liver disease. This new technology takes mesenchymal stem cells from adipose (fat) tissue and coaxes them to function like hepatocyte (liver) cells. The purpose of the collaboration is to move this technology to early clinical trials and study its effect on people with liver damage from alcohol-related hepatitis.

Mesenchymal stem cells are adult stem cells that have been well studied and have been shown to be safe in humans.

Mayo Clinic brings to the collaboration expertise in regulatory affairs, clinical trials, product development and biomanufacturing. HepaTx brings a new cell technology directed toward a disease with few therapeutic options. Together they will work to advance the engineered liver cells to first-in-human safety studies.

"Our goal in working with industry is to quickly bring a pipeline of cell-based therapeutics to patients with unmet needs," says Julie Allickson, Ph.D., chief technology officer at Mayo Clinic's Center for Regenerative Biotherapeutics. "This is a very exciting opportunity to pair Mayo Clinic's know-how with a new discovery aimed at improving the health, lives and therapeutic outcomes for patients."

A new cell-based therapy for liver disease

Excessive alcohol use damages and eventually destroys liver cells, causing inflammation that can lead to abdominal pain, scarring and liver failure. Alcoholic hepatitis is one type of chronic liver disease that affects 20-40% of heavy drinkers.

In the early stage of liver disease, treatment is aimed at managing the symptoms through a combination of small molecule drugs and quitting drinking. However, in later stages, cell and tissue damage are often irreversible. People with end-stage liver disease may need an organ transplant to survive.

The engineered liver cell technology from HepaTx is so new that it has never been manufactured on a large scale for patients. That's where the Center for Regenerative Biotherapeutics process development experts come in. They develop standard operating procedures —a blueprint of sorts — for biomanufacturing in Mayo Clinic's state-of-the-art current Good Manufacturing Practice (cGMP) facilities. CGMP refers to a set of practices that ensures a new therapy meets strict quality control and quality assurance standards for medicines made from living sources such as cells.

"We engage with investigators at proof of concept. We guide the technology through process development to identify any gaps in safety that could delay regulatory approval for a clinical trial," says Dr. Allickson. "Our biomanufacturing infrastructure is based on industry best practices, which positions us well to work with outside collaborators to advance a new therapy toward market approval for patients."

Mayo Clinic will lead the early clinical trials in which patients with alcohol-related hepatitis will be infused with the engineered liver cells. The research will focus on safety and effectiveness of this cell replacement therapy in repairing late stage disease.

Working with industry collaborators that are aligned with Mayo Clinic values is a strategic priority for the Center for Regenerative Biotherapeutics.

Mayo Clinic has a financial interest in the technology referenced in this article. Mayo Clinic will use any revenue it receives to support its not-for-profit mission in patient care, education and research.

A recent study suggests that severe alcohol-related liver disease is on the rise, especially in young adults. There appears to be an increase in those who are at greater risk of cirrhosis, liver cancer and death, according to the study published in JAMA. And the potential cause is binge drinking.

Binge drinking is a pattern of drinking where a male consumes five or more drinks within two hours or a female consumes at least four drinks within two hours. Heavy drinking can cause hepatic steatosis, or increased fat in the liver, and alcoholic hepatitis, or inflammation of the liver. Over time, heavy drinking can cause cirrhosis, which is scarring and destruction of liver tissue.

In this Mayo Clinic Radio podcast, Dr. Doug Simonetto, a Mayo Clinic gastroenterologist and hepatologist, will discuss diagnosis and treatment options for liver disease. Also on the program, Dr. Hector Villarraga, a Mayo Clinic cardiologist, will explain the growing field of cardio-oncology. And Dr. Yonas Geda, a Mayo Clinic neurologist, will share how lifestyle factors can affect brain health.

EXPERT ANSWERS
Is there any link between cellphones and cancer?
The possible connection between cellphones and cancer is controversial. Many years' worth of studies on cellphones and cancer have yielded conflicting results. Learn more from Dr. Edward Creagan, an emeritus Mayo Clinic oncologist.

What's the best frequency for aerobic workouts?
Any type of aerobic activity contributes to cardiovascular fitness. Even dividing up your activity time, such as a few five-minute walks spread throughout the day, offers aerobic benefits. And longer, less frequent sessions of aerobic exercise have no clear advantage over shorter, more frequent sessions of activity. Learn more from Dr. Edward Laskowski, a Mayo Clinic physical medicine and rehabilitation specialist and co-director of the Mayo Clinic Sports Medicine Center.

HEALTH TIP OF THE WEEK
Too sick to exercise?
The common cold doesn't have to keep you on the sidelines. Mild to moderate exercise is usually OK if your symptoms are all above the neck, such as a runny nose, nasal congestion, sneezing or a minor sore throat. However, if your symptoms are below the neck, such as chest congestion, a hacking cough or an upset stomach, delay your workout. And don't exercise if you have a fever, fatigue or widespread muscle aches.
