MD 2009 – Influenza – Next Generation
Anti Virals
 Background
The emergence of Oseltamivir (Tamiflu®) resistant viruses has
highlighted the need for the development of new anti viral drugs (CDC
March, 2009)

Drug Resistance
- Oseltamivir (Tamiflu) - ≥ 95% resistance to Tamiflu reported to
seasonal influenza H1N1
- Concerns Tamiflu resistant strains genetically combine with other flu
strains, e.g. Influenza A (H1N1 – 09)/swine flu or H5N1 (avian) with
greatly increased risk of lethal pandemic. Tamiflu resistance to swine flu
(H1N1) now noted.

Incidence
Each year in the U.S.
- 5% to 20% of population may get the flu
- About 36,000 people die from post flu related causes and up to
500,000 die world wide
6
MD 2009 Influenza Anti Virals

Clinical Need

Seasonal Influenza
- 5% to 10% world population infected
- Increasing drug resistance
- ‘Flu vaccines often inadequate

Pandemic influenza threat
- New ‘flu viruses
- No/low population immunity
- Governments stockpile
- Tamiflu resistance appearing worldwide
Influenza A (H1N1-09/swine flu) virus has resulted from
triple recombination of human, avian and swine influenza
viruses (NEJM , April 2009)
7
MD 2009 Influenza Anti Virals
Capability
Key scientific staff :





Design & synthesis (with others) of the 1st and 2nd generation
anti flu drug – neuraminidase inhibitors
Patents granted over 1st and 2nd generation anti flu drugs –
neuraminidase inhibitors
Are uniquely placed to develop next generation anti virals
Over past months conducted research, planning & design for
“next generation” anti ‘flu drugs
Wen-Yang Wu awarded National Clunies Ross National and
Scientific Award for his contribution to Australian science (2000)
e.g. design and synthesis zanamivir (Relenza).

MD 2009 Influenza Anti Virals
Key Advantages
Flu drug candidates: New Design, different mode of action.
 With resultant
 Improved therapeutic performance





Improved Anti Viral Potency
Reduced side effect profile
Protects against flu strains not included in vaccine(s)
Provides potential for efficacy against avian and swine influenza strains
Provides alternative therapeutic for those in whom vaccination is contra
indicated
No existing antiviral has all of these characteristics
