Evolving Influenza Virus Strains

The continuous evolution of influenza virus strains is a major driving force behind the demand for updated medications and vaccines in Japan. Influenza viruses are highly mutable and exhibit significant genetic variability, which results in the frequent emergence of new strains. These genetic shifts, including point mutations and reassortments, can lead to the development of novel virus variants that may bypass the immunity conferred by previous vaccinations or past infections. This constant change in the viral landscape creates a pressing need for new and updated therapeutic and preventive measures. Each flu season, the influenza virus undergoes genetic changes that can alter its antigenic properties. This phenomenon, known as antigenic drift, occurs when small mutations accumulate in the virus’s surface proteins, hemagglutinin (HA) and neuraminidase (NA). These minor changes can lead to the emergence of new strains that are sufficiently different from those that circulated in previous seasons. Consequently, individuals who were previously vaccinated or infected may not have adequate immunity against these new strains, underscoring the need for updated vaccines and antiviral drugs.

In addition to antigenic drift, a more dramatic form of genetic change known as antigenic shift can occur. Antigenic shift involves the reassortment of genetic material between different influenza virus strains, potentially creating a novel influenza subtype with significantly different HA or NA proteins. This can lead to the emergence of pandemic strains to which the population has little pre-existing immunity. Historical examples include the H1N1 pandemic of 2009, which was caused by a new strain resulting from antigenic shift. The potential for such major shifts necessitates ongoing vigilance and rapid response in vaccine and drug development to address emergent threats. Pharmaceutical companies and research institutions play a crucial role in responding to these evolving viral strains. They continuously monitor influenza virus trends through global surveillance networks, such as the World Health Organization’s (WHO) Global Influenza Surveillance and Response System (GISRS). These networks provide real-time data on circulating strains, enabling scientists to identify which virus variants are most likely to dominate in the upcoming flu season. This information is critical for the timely development of vaccines and antiviral medications that are effective against the currently circulating strains.

Key Market Challenges

Resistance to Antiviral Drugs

One of the major challenges facing the Japan Influenza Medications Market is the increasing resistance of influenza viruses to antiviral drugs. Over time, influenza viruses can develop mutations that render existing antiviral medications less effective.

This analysis revisited a previous study that had limitations, including the lack of probabilistic sensitivity analysis and the use of EQ-5D-3L quality of life scores instead of the more current EQ-5D-5L. The earlier study also used a decision tree model that considered only three health conditions. In the updated analysis, new data from a network meta-analysis were incorporated, and a revised decision tree model was constructed to include seven health conditions. Costs were assessed based on the 2020 Japanese medical fee index, including both medical costs and drug prices. Effectiveness was measured using EQ-5D-5L questionnaires for adult patients with recent influenza virus infections over a 14-day period. Deterministic and probabilistic sensitivity analyses were conducted to assess uncertainty. The initial analysis confirmed that oseltamivir was more cost-effective compared to laninamivir, zanamivir, and peramivir, establishing it as the most cost-effective neuraminidase inhibitor. The updated examination further validated that oseltamivir continued to dominate the other neuraminidase inhibitors. Both deterministic and probabilistic sensitivity analyses consistently supported oseltamivir as the most cost-effective option among the four drugs.
