AIDS experts say a study starting in Johannesburg next month could lead to better‚ safer and cheaper HIV treatment.
In the best-case scenario‚ two new drug combinations could by 2019
treat an additional 2-million people without an increase in cost.
Writing in the January issue of the SA Medical Journal‚ 23 experts
express excitement about the possibilities of the study — dubbed Advance
— which will involve 1,100 participants over 96 weeks.
"In an age of escalating medical costs‚ we are seldom presented with a win-win scenario with regard to clinical care‚" they say.
"If successful‚ patients will benefit with a much safer and more
forgiving regimen in a smaller tablet‚ government and other funds will
save money while pharmaceutical producers will have simplified
manufacturing‚ using lower volumes of active … ingredients.
"The clinical studies and registration processes to secure inclusion
of these two new drugs‚ if successful‚ would be a huge South African
victory."
Francois Venter of the Wits Reproductive Health and HIV
Institute said that by mid-2016 South Africa had 3.4-million people on
the world’s largest HIV treatment programme‚ collectively using a
quarter of all generic antiretrovirals available worldwide.
"An
increase in public spending is expected to continue‚ owing in part to
recent changes in antiretroviral therapy initiation guidelines‚" he
said.
"The Department of Health announced its endorsement to
‘treat all’ approaches from September 2016 … theoretically doubling the
number eligible for ART."
With 600,000 people a year expected to
need medication and HIV-positive patients surviving for longer thanks to
the treatment‚ annual costs of R4.9bn were set to reach R6.3bn by 2019.
However‚
two cheaper drugs were being licensed to manufacturers of generic
medication. One‚ dolutegravir‚ had fewer side-effects and higher
virological resistance; the other‚ tenofovir alafenamide‚ was less
harmful to bones and kidneys.
Combining the new drugs with other
medicines "would also substantially reduce the size of the current
tablet‚ making it easier to manufacture‚ while saving on packaging and
storage space".
The aim of the Advance study‚ said Venter‚ was to provide evidence needed to change treatment guidelines.
"Results
may be available by the end of 2018 for Medicines Control Council
registration and Department of Health guidelines and tender processes‚
so that the new regimen can be rolled out from 2019."
The study‚
funded by the US Agency for International Development and the global
health initiative Unitaid‚ has been designed by a multidisciplinary
group of researchers‚ doctors‚ activists‚ donors and public health
specialists. It has backing from the Department of Health and the World
Health Organisation.
"The introduction in South Africa of this new
regimen has the potential to substantially reduce the cost of
first-line ART‚ while also being safer and better tolerated‚ therefore
limiting the need for second-line ART‚" say the experts.
"We
estimate potential cost-savings for South Africa if the studies
demonstrate efficacy and safety‚ and justify the urgency in completing
the study swiftly and transitioning to the new combination without
delay."
