Antivirals

Dr. Liotta has helped transform HIV/AIDS from a death sentence to a chronic infection in which patients can live active and productive lives. The Emory University Office of Technology Transfer estimates that about 95% of the people living with HIV/AIDS in the U.S., and many around the world, take or have taken one of the drugs co-invented by Dr. Liotta.

Dr. Liotta is most noted for his invention of emtricitabine and lamivudine, along with Drs. Raymond Schinazi and Woo-Baeg Choi. These two drugs are widely used as crucial components of anti-HIV combination therapies. They played instrumental roles in combating the HIV/AIDS epidemic in the U.S. and curbing the spread of HIV in other regions of the world. Millions of HIV/AIDS patients can live long and near-normal lives because of the discovery of emtricitabine and lamivudine. Emtricitabine, marketed under the name Emtriva®, made possible the first-ever combination therapy for HIV/AIDS as a once-daily pill. It is a component of many combination therapies used to treat HIV/AIDS, including Truvada®, Atripla®, Complera®, Stribild®, Genvoya®, Odefesey®, Biktarvy®, Descovy®, and Symtuza®. In addition to its use as a therapeutic, emtricitabine is also used in combination with other antivirals to protect healthy individuals from acquiring HIV – known as Pre-Exposure Prophylaxis or PrEP. Lamivudine, marketed under the name Epivir®, is a component of multiple combination therapies such as Combivir®, Trizivir®, Epzicom®, Triumeq®, Dutrebis®, and Delstrigo®. Notably, lamivudine also became the first drug approved by the FDA to treat hepatitis B infections. Both emtricitabine and lamivudine are on the World Health Organization’s List of Essential Medicines.

Other Therapeutic Areas

While Dr. Liotta’s most significant impact has come from the HIV/AIDS therapeutics, he has also made important contributions to other therapeutic fronts, such as oncology and neurological diseases. He co-discovered samuraciclib (formerly CT7001), a CDK7 inhibitor for treating hard-to-treat cancers. Samuraciclib is in Phase 2 clinical trials and has been fast-tracked by the FDA for use in two combination therapies to treat certain breast cancers. He also developed Q-122, an oral drug for controlling hot flashes in postmenopausal women, which has completed a Phase 2 clinical trial. In addition, his collaboration with Dr. Stephen Traynelis in Emory’s Department of Pharmacology and Chemical Biology laid the foundation for the discovery of NP-10679. NP-10679 successfully wrapped up its Phase 1 clinical trial and has received Orphan Drug designation from the FDA for treating subarachnoid hemorrhage or bleeding in the space around the brain.

In addition to scientific research and innovations, Dr. Liotta values the power of teaching and mentorship. The training and education of students and junior scientists is an essential component of Dr. Liotta’s career. His laboratory has a strong track record in cultivating the next generation of scientists and innovators. To date, he has mentored and supervised nearly 300 undergraduate and graduate students, postdoctoral fellows, research scientists, and visiting scholars – including ~100 undergraduate students, ~100 graduate students, and ~70 post-graduates.

Dr. Liotta always encourages his students and mentees to think independently. He generously provides them with abundant resources for their research projects and career development. Many alumni from his laboratory have successful careers in a wide array of sectors, including academia, the biotech and pharmaceutical industry, intellectual property law and technology transfer.

As a caring humanitarian, Dr. Liotta has devoted incredible efforts to improving human health worldwide, especially in underserved regions. Over the past twenty years, he initiated a series of outreach activities to cultivate the next generation of African scientists, implementing unique mechanisms to provide them with the scientific skills and business acumen required to address African healthcare needs.

In 2008, Dr. Liotta started iThemba Pharmaceuticals, a South African biotech firm focusing on developing medicines to treat diseases hitting Africa the hardest, such as HIV, tuberculosis and malaria. The company operated under a unique business model: it started out by pursuing contract research work in medicinal chemistry, such as custom synthesis and scale-up synthesis, the revenue from which was then utilized to fund its internal drug discovery efforts. Although a lapse in funding from the South African government led to the shutdown of iThemba Pharmaceuticals, it cultivated many talents in Africa and helped lay the foundation from which a biotechnology industry can grow.In 2008, Dr. Liotta started iThemba Pharmaceuticals, a South African biotech firm focusing on developing medicines to treat diseases hitting Africa the hardest, such as HIV, tuberculosis and malaria.
