London - Generic manufacturers are to be given a free rein
to make cheap copies of Johnson & Johnson's HIV/AIDS drug Prezista for sale
in Africa and other poor countries.
US healthcare group J&J said on Thursday it would not
enforce patents, provided generic firms made high-quality versions of the drug
- known generically as darunavir - for sub-Saharan Africa and Least Developed
Prezista is a relatively new drug used when patients develop
resistance to older antiretrovirals. The need for it was expected to grow
rapidly as more patients in Africa stop responding to existing therapies.
Pharmaceuticals head Paul Stoffels said he expected Indian
drugmakers, in particular, to take advantage of the patent move, adding that
competition among different companies should drive prices down further.
J&J has an existing deal with South African group Aspen
Pharmacare, which makes Prezista at a discounted price of $2.22 per day for
Africa - a fraction of the western market price.
Its decision to act unilaterally on Prezista patents will,
however, disappoint those calling for J&J to share intellectual property
rights in the new Medicines Patent Pool, which aims to streamline generic
production by pooling patents.
"We have chosen to go direct ... we think that is the
best way," Stoffels said in an interview.
"We want to reserve the right to reinforce patents if
people are not providing the right quality of product, for example by bringing
products to market that under-dose."
International drugmakers are under growing pressure to make
medicines more affordable in poor countries, after being attacked for not doing
enough in the past.
J&J ranked second in a new analysis of how companies are
performing in providing access to medicines - an improvement of seven places
from two years earlier, following its purchase of Crucell, which makes vaccines
for the developing world.
