04/08/2022

Announcement of Patent Grant (Patent Grant) for 5-Aminolevulinic Acid (5-ALA) for Treatment and Prevention of COVID-19

We are pleased to announce that Nagasaki University*1 (1-14 Bunkyo-machi, Nagasaki City, President: Shigeru Kawano; hereinafter “Nagasaki University”) and NeoPharma Japan Co., Ltd.*2 (6-2-6 Kojimachi, Chiyoda-ku, Tokyo, CEO: Satoshi Kawada; hereinafter “NPJ”) have obtained a patent for the treatment and prevention of COVID-19 using 5-aminolevulinic acid (5-ALA).

【Patent Details】

Publication Number: Japanese Patent Laid-Open No. 2022-8060(P2022-8060A)

Title of Invention: Agent for Treatment and/or Prevention of Novel Coronavirus Infection (COVID-19)

Publication Date: January 13, 2022 (2022.1.13)

 

【Overview】

COVID-19, which was first reported in December 2019, is a novel pneumonia caused by the novel coronavirus, SARS-CoV-2. As a result of rapid increases in patient numbers worldwide, over 150,000 deaths have been reported. In Japan, the spread of COVID-19 has been observed since early 2020, and various research institutions have been conducting studies on the virus causing COVID-19.

Until now, Professor Kiyoshi Kita, Head of the Graduate School of Tropical Medicine and Global Health at Nagasaki University, and NPJ have been focusing on the functionality of 5-ALA in developing treatments for malaria. In the process, they anticipated the effects of 5-ALA against SARS-CoV-2 and started research on COVID-19.

As a result, they demonstrated that 5-ALA powerfully inhibits the infection of SARS-CoV-2 in cultured cells. This antiviral effect was observed without significant cytotoxicity in both human and non-human cells*4 and has been confirmed against various variants, including the Delta variant*5. Recently, concentration-dependent inhibitory effects against the Omicron variant were confirmed in cell-based tests*6. Utilizing these joint research results, a patent application was filed and has now been granted. It is expected that 5-ALA will be used as a material for tackling COVID-19 in the future.

*3 5-Aminolevulinic Acid (5-ALA)

Humans, animals, and plants maintain their vital functions by producing energy within cellular organelles called mitochondria. 5-aminolevulinic acid (5-ALA) plays a crucial role in the functioning of mitochondria. 5-ALA ultimately converts into a substance called “heme” within the mitochondria. Heme is an essential component of “cytochromes,” proteins necessary for energy production. Furthermore, 5-ALA has been safely used in health foods, cosmetics, pet supplements, feed, and fertilizer for over a decade. 5-ALA has also been approved as a diagnostic drug for visualizing brain tumors and bladder cancer in the field of cancer. Additionally, 5-ALA is known to enhance mitochondrial function, and a phase III clinical trial led by Saitama Medical University is currently underway to investigate its effects on mitochondrial diseases.
