Herpes Treatments 2023
The U.S. Centers for Disease Control and Prevention (CDC) says there is no cure for herpes as of 2023. However, the use of antiviral medicine shortens herpes outbreaks. According to Technavio, there were about 15 vendors in the herpes treatment market. According to FMI data, the size of the global herpes labialis treatment market might increase from US$ 1.13 billion in 2023 to US$ 1.79 billion by 2033. In addition, the Acyclovir product segment reported a significant market share (50.44%) in retail pharmacy.
Acyclovir is U.S. FDA-approved to decrease pain and speed the healing of sores or blisters in people with varicella, herpes zoster, and first-time or repeat genital herpes outbreaks. Acyclovir is also sometimes used to prevent outbreaks of genital herpes in people who are infected with HSV. Acyclovir is in a class of antiviral medications called synthetic nucleoside analogues. However, Acyclovir (valacyclovir 500 mg) will not cure genital herpes and may not stop the spread of genital herpes to other people.
Zydus Cadila commercializes Acyclovir Ointment USP (US RLD Zovirax), 5%. The first onset of genital herpes is treated with this medication. Those with weakened immune systems can also use it to treat lip and skin herpes infections that are not life-threatening.
Cipla Ltd. offers antiviral medicines treating viral infections like herpes labialis, herpes simplex, shingles, and genital herpes infection called ACIVIR 200 DT and ACIVIR 400 DT tablets.
Herpes Treatment Candidates 2023
AiCuris's Pritelivir (AIC316) is a potent inhibitor of HSV replication that belongs to a new chemical class and acts via a novel mechanism of action. In contrast to currently used nucleoside analogues, Pritelivir does not require activation by viral enzymes and can thus protect uninfected cells. On March 1, 2023, a clinical study suggested Pritelivir was safe and well tolerated, up to 600 mg following single and up to 200 mg following multiple once-daily doses. Considering a therapeutic dose of 100 mg once daily, pritelivir demonstrated a favorable safety, tolerability, and pharmacokinetic profile in healthy subjects to support further development. However, Pritelivir does not cure herpes.
Laboratoire Boreaderme Inc. and Ecogene 21 announced in September 2020 that they are focused on a Phase 2 clinical study to evaluate the safety profile of BOR15001L7 to docosanol 10% for managing cold sores in patients with recurrent herpes labialis.
A study published in May 2023 found that a molecule can effectively treat the lesions accompanying shingles and suggests the molecule may also work against the viruses that cause oral and genital herpes.
Herpes Tests 2023
The WHO announced in July 2023 that a new report on the Diagnostics Landscape for Sexually Transmitted Infections highlights diagnostics available to support scale-up of screening for STIs, including herpes. The U.S. Preventive Services Task Force published in February 2023 recommendations on screening for genital herpes infection in asymptomatic adults and adolescents, including pregnant individuals. Mylab Discovery Solutions in India launched the PathoDetect™ HSV Type 1& 2 Detection kit, a multiplex real-time PCR test that detects and differentiates HSV-l and HSV-2 in a single tube. And LabCorp Herpes Simplex Virus Types 1/2, DNA PCR.
Genital herpes is caused by herpes simplex virus type 1 (oral) and type 2, a common sexually transmitted disease (STD) associated with substantial health losses. To advance research to understand and address HSV infection, the U.S. National Institutes of Health (NIH), in September 2023, established the Strategic Plan for Herpes Simplex Virus Research 2023-2030. This plan aligns with ongoing national efforts, including the Sexually Transmitted Infections (STI) National Strategic Plan. A study published in 2023 estimated 0.05 lifetime quality-adjusted life years lost per incident infection, equivalent to losing 0.05 years or about 18 days of life for one person with perfect health.
A study published in October 2023 identified that increased serologic titers of herpes simplex virus 2 were associated with reduced whole-brain cortical thickness, and a combined score of HSV-2 and C. pneumoniae displayed an additive effect on reduced cortical thickness. These findings suggest HSV-2 seropositivity may contribute to accelerated brain aging, possibly resulting in an increased vulnerability to cognitive impairment and neurodegenerative disease in aging populations.
As of 2023, the U.S. FDA has not approved a herpes vaccine candidate.
