New Zealand HIV Patients Given Hope

New Zealand HIV Patients Given Hope

With New Medication

New Zealand HIV patients who were facing a bleak future, will now have a new treatment option thanks to ISENTRESSTM (raltegravir) being approved for use in New Zealand yesterday.

Dr Simon Briggs, Infectious Diseases Physician at Auckland City Hospital, says, "This is great news for people with HIV infection, and for the doctors treating them, as there is a real need for new HIV treatments in New Zealand."

ISENTRESS is used in combination with other HIV medications and is for patients whose HIV has developed resistance to a number of the existing HIV treatments. In New Zealand there are approximately 40 people who are in this position. The availability of ISENTRESS is timely as some of these patients have been waiting for new HIV treatments for a long time. The next few years will see increasing numbers of patients requiring ISENTRESS.

ISENTRESS is the first in a new class of medications called integrase inhibitors. It works by preventing HIV viral DNA inserting into human DNA thereby blocking the ability of the virus to replicate and infect new cells.

Eamonn Smythe, National Positive Health Manager for the New Zealand AIDS Foundation, also welcomed the registration of ISENTRESS in New Zealand. "ISENTRESS becoming available here is extremely good news for people living with HIV as we haven't had a new class of medication since the introduction of FUZEON, which has to be injected rather than taken as a tablet.

"Resistance to current HIV therapies in treatment-experienced patients is one of the leading challenges in effective HIV treatment. Without access to new classes of medication, people may build resistance to current therapies and unless new classes of medications are developed, the long term quality of health for those living with the virus may be jeopardised." added Mr Smythe.

While in New Zealand HIV is not as prevalent as in other parts of the world, in 2007 one hundred and fifty six new cases were diagnosed. Of those, 31 men and 29 women were infected through heterosexual contact although most acquired HIV overseas.

ISENTRESS has been developed by Merck & Co Inc., known in New Zealand as Merck Sharp & Dohme (MSDNZ). MSDNZ Managing Director, Alister Brown, says, "ISENTRESS has taken 14 years to develop but it has arrived just as New Zealand starts to see a need for new treatments.

"This medication is funded by the Government in Australia and the United Kingdom and is showing very positive results. We are waiting on PHARMAC to review our application for funding and hope that we will soon be able to offer ISENTRESS to all New Zealanders who would benefit from it." Ends
