HIV, hepatitis B and C and tuberculosis (TB) can each be treated
for less than $90 a year where generic drugs can be made available, Dzintars
Gotham of Imperial College, London, reported at the 9th International
AIDS Society Conference on HIV Science (IAS 2017) in Paris on Tuesday.
The findings come from an analysis of the prices paid for
the raw materials that are used to make drugs for the treatment of each
disease, and the costs of manufacturing each product.
Although the cost of antiretroviral treatment has fallen
dramatically since generic manufacturers first began to manufacture versions of
antiretroviral drugs in India in 2001, generic products have not been available
in all countries due to patent restrictions. Over the next few years it will begin
to be possible to provide first-line treatment for HIV using generic drugs as
patents expire on some of the key drugs used in HIV treatment.
The cost of treating other diseases remains extremely high
in most countries, and is affected not only by patent restrictions, but also by
the ability of governments to negotiate competitive prices. Dr Gotham said that
the cost of treating hepatitis C with a 12-week course of sofosbuvir and
daclatasvir ranges from $108 in India and $174 in Egypt, to $11,598 in Australia,
$29,361 in Brazil and $47,972 in Argentina.
To achieve global targets for HIV treatment and viral
suppression, hepatitis C elimination and reducing the burden of TB
and drug-resistant TB, large increases in the number of people
treated for each disease will be necessary. Cutting the prices paid for
medicines will be essential if countries are to afford large treatment
programmes for HIV or viral hepatitis.
In particular, countries that are seeking to move to
treat-all targets will have to have keep up with the growth in newly-infected
people, Dr Andrew Hill of Liverpool University told a symposium on how to
reduce drug costs. The number of people who will need HIV treatment is likely
to grow at a rate of 800,000 a year, from 30 million in 2017 to 36.4 million in
2025, he pointed out, while the current rate of hepatitis C infections means
that the global burden of disease will remain the same at current treatment
levels up to 2030, the target date for elimination of hepatitis C.
To find out what scope might exist for further price
reductions, Dzintars Gotham and researchers from Howard University, Washington
DC, St Stephen’s AIDS Trust, London, the University of Liverpool and the
University of Cambridge looked at costs of shipments of active pharmaceutical
ingredients (API), the raw material of drug manufacture, in and out of India.
Until November 2016 information on the value of shipments of
APIs was freely available from the India customs service. The research group
used these costs and added manufacturing costs calculated from a range of
published and unpublished sources, and added a 10% profit margin. Their prices
did not include the costs of bioequivalence studies for regulatory approval or
transport.
They compared their calculated costs to the lowest prices currently available from generic manufacturers according to the Médecins Sans Frontières 2016 guide to antiretroviral drug costs.
They
found that there is scope for further reductions in the costs of
several widely used antiretroviral drugs in lower and lower-middle
income countries, and also showed how far higher-income countries can
expect to reduce treatment costs as antiretroviral drugs begin to go off
patent over the next few years.

High-quality regimens for the treatment of each
disease can now be produced for less than $90 per course of treatment or
per year, and there is no need for governments or donors to pay more,
provided that intellectual property restrictions can be overcome.
Countries and donors should aim for a new $90-$90-$90 target on HIV,
viral hepatitis and TB drug prices if the current global targets for
disease elimination are to be achieved, he concluded.
The lack of accurate information on current prices – and
potential future prices – is deterring governments and donors from scaling up
treatment for hepatitis C, speakers at the symposium on drug pricing agreed.
“Donors need to understand just how cheaply these drugs can
be made. It’s misleading for Gilead to say that they can offer sofosbuvir for
$900 when we’ve shown that it can be made for $90,” said Andrew Hill.
“One of the most important things we have to do is re-frame
[the debate about hepatitis C drug prices]. The focus on $1000 a pill has done
us a disservice with donors. We need to be talking about a $150 course of
treatment,” said Dr Margaret Hellard of the Burnet Institute, Melbourne
Governments also need to adopt a tougher stance in price
negotiations and start thinking in terms of their strategic aims for public
health, several panellists argued.
“One of the jobs of government should be negotiating hard
for the best price and not just accepting the price offered,” said Margaret
Hellard. “We need our governments to make strong and brave decisions on behalf
of their people.”
