CHICAGO — Ten patients at Penn Medicine have been cured of the Hepatitis C virus (HCV) following lifesaving kidney transplants from deceased donors who were infected with the disease. The findings point to new strategies for increasing the supply of organs for the nation’s more than 97,000 patients who are awaiting kidney transplants – often for as many as five or more years.

In 2016, Penn Medicine launched an innovative clinical trial to test the effect of transplanting kidneys from donors with HCV into patients currently on the kidney transplant waitlist who do not have the virus, and who opt in to receive these otherwise unused organs. Recipients were then treated with an antiviral therapy in an effort to cure the virus. Early data from the study were presented today by David S. Goldberg, MD, MSCE, an assistant professor of Medicine and Epidemiology in the Perelman School of Medicine at the University of Pennsylvania, at the 2017 American Transplant Congress in Chicago, and were simultaneously published in the New England Journal of Medicine.  

“We started this trial in the hopes that, if successful, we could open up an entirely new pool of donor organs, and effectively transplant hundreds, if not thousands, more patients who are awaiting a lifesaving organ,” Goldberg said. “Historically, Hepatitis C-infected kidneys were often discarded, and were thought to be damaged or too ‘high-risk.’ Our pilot data demonstrate the ability to cure the contracted virus following transplantation in this patient population. If future studies are successful, this may be a viable option for patients who may otherwise never see a transplant.”

Goldberg, who co-led the study with Peter Reese, MD, MSCE, an assistant professor of Medicine and Epidemiology at Penn and chair of the Ethics Committee for the United Network of Organ Sharing (UNOS), approached and enrolled participants who relied on dialysis treatments to stand in for their damaged kidneys. Participants were between 40 and 65 years of age and had been waiting for a transplant for at least a year and a half. A three-step process of education and consent was used during pre-enrollment to ensure patients, and their loved ones were provided with a comprehensive understanding of the risks. Once enrolled, and as organs became available, the team performed HCV donor genotyping during the allocation process, selecting only kidneys that were considered “high quality.”

In the first phase of the study, to date, 10 patients have received transplants using the protocol. On average, patients received a transplant 58 days after enrolling in the trial—some in as quickly as 11 days, while others waited for over 100 days. At three days after surgery, patients were tested for HCV, and all 10 tested positive for the disease. Next, the participants were treated with the standard 12-week course of elbasvir/grazoprevir, commonly known as Zepatier, a recently-approved and highly effective oral medication prescribed to eradicate HCV. All 10 patients have been cured of their contracted HCV.

“For so long, HCV was a virus with a very negative stigma associated with it, especially among physicians. So it was interesting to see that patients were quick to jump at the chance to get this transplant, despite the possibility that they could get Hepatitis C permanently,” Reese said. “Going into the study, we knew it was a possibility that some or all of the patients would contract HCV, and that they could have the disease for the rest of their lives if we were unsuccessful. But for these patients, getting off of dialysis and getting back to their normal lives was very much worth the risk.”

Following the early positive results, the research team was granted an extension of their study, which will allow them to transplant and treat an additional 10 patients—20 patients in total.

The research team is designing a new clinical trial that will study this same approach in patients who are heart transplant recipients, and in the future they hope to examine the efficacy of this approach in liver and lung transplants. Researchers note there is a need for longer and larger trials to continue evaluating the effectiveness of HCV-positive to HCV-negative transplantation followed by antiviral therapy in a broader population.

Additional Penn Medicine experts involved in this study span disciplines including infectious diseases, transplantation surgery, gastroenterology, hepatology, and pathology and laboratory medicine, including Deirdre Sawinski, Roy Bloom, Raj Reddy, Emily Blumberg, Jennifer Trofe-Clark, Vivianna Van Deerlin, Midhat Farooqi, Peter Abt, Matthew Levine, Paige Porrett, Susanna Nazarian, Ali Naji, Maureen McCauley, and Anna Sicilia. The study is supported by a research grant from the Merck Investigator Initiated Studies Program, and Merck supplied the antiviral drugs used in the study.

Penn Medicine is one of the world's leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation's first medical school) and the University of Pennsylvania Health System, which together form a $6.7 billion enterprise.

The Perelman School of Medicine has been ranked among the top five medical schools in the United States for the past 20 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $392 million awarded in the 2016 fiscal year.

The University of Pennsylvania Health System's patient care facilities include: The Hospital of the University of Pennsylvania and Penn Presbyterian Medical Center -- which are recognized as one of the nation's top "Honor Roll" hospitals by U.S. News & World Report -- Chester County Hospital; Lancaster General Health; Penn Wissahickon Hospice; and Pennsylvania Hospital -- the nation's first hospital, founded in 1751. Additional affiliated inpatient care facilities and services throughout the Philadelphia region include Good Shepherd Penn Partners, a partnership between Good Shepherd Rehabilitation Network and Penn Medicine.

Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2016, Penn Medicine provided $393 million to benefit our community.
