Natco seeks Pfizer nod for drug clone
5 JAN, 2011, 06.31AM IST, KHOMBA SINGH,Economic times
NEW DELHI: Natco Pharma has sought a voluntary licence from Pfizer to
make and sell copies of the US company's HIV medicine in India, a
first step to a provision that permits firms to legally make patented
drugs of other companies.
Natco sent a notice to the US drugmaker in November saying Pfizer's
drug was too expensive for HIV patients in India, and that Natco can
sell its own product at about one-fifth the price, two people with
direct knowledge of the development told ET.
This is the first step in what is known in pharma industry as
Compulsory Licensing(CL), a provision that allows generic drugmakers
to make and sell low-cost version of a patented drug under certain
conditions. Natco is the first company to initiate the process for CL
in the country and this will be a big test case for application of the
provision in India.
In all probability, Pfizer will reject Natco's request saying that it
has spent huge amount of money to develop the drug, the first person
said, asking not to be named. "This will be the acid test and set a
precedent for the use for CL to make medicines affordable for masses
in India," he said. Natco executives declined to comment while Pfizer
did not reply to an e-mail query. The Hyderabad-based Indian company
has also informed the government about its notice to Pfizer, a senior
commerce ministry official who has seen a copy of the notice said.
Pfizer has time till May to reply, as Indian patent law allows an
innovator company to respond within six months of receiving a notice
for voluntary license. If it does not allow Natco to make cheap drugs,
the Indian pharma company can approach the government for CL, that
will allow it to sell a lowpriced version of the drug after paying
royalty to Pfizer.
The government can invoke the provision after three years of the grant
of the patent under certain conditions such as the product is not
available at an affordable price for public or the patent holder fails
to launch the product within a stipulated time.
Pfizer's HIV drug maraviroc sold under the brand Celsentri costs
about . 65,000 for a month dosage, said Natco in its notice to the
world's largest drugmaker. The Indian company has said it can make a
copy that will cost . 15,000 a month to HIV patients, the commerce
ministry official said. Pfizer got the patent for maraviroc in January
2007, one of the first HIV drugs to be patented in India. The
country's drug regulator had given marketing approval for maraviroc
tablets (150mg & 300mg) in November 2009, its website said. According
to Jayanti Patel a Mumbai based stockist for Pfizer and vice president
of the city's Wholesalers' Association, the drugmaker had imported a
few samples of Celsentri mainly for clinical trials and is not
currently available with stockists.
The fate of the case this year and the government's response could
shake up foreign drugmakers' ability to sell high priced patented
products in India. Global innovator companies have been opposed to the
CL provision . "Proposals to promote the use of CL could inhibit
technological development in the sector in India and thereby undermine
efforts to make medicines and other products widely available to
patients," Tapan Ray , director general of Organisation of
pharmaceutical producers of India , had said in its response to a
government's discussion note regarding the use of CL in last
September. OPPI, the lobby body of innovator companies in India, said
that sales of patented products account for much less than 1% of the
Indian Pharmaceutical market.
Although four years ago, Natco had unsuccessfully tried to seek CL for
Pfizer's cancer drug to be sold in Nepal no local drugmaker has tried
to invoke the provision in India as they say the process is not well
crafted. India adopted a new patent regime in 2005 that introduced the
provision of CL but has various loose ends.
C M Gulati, editor, of monthly medical journal MIMS said that CL can
be given for several patented drugs in India but most of the local
companies with the expertise to make such complicated drugs cannot
apply. Half of the leading companies have been taken over by foreign
firms while the others have marketing alliance with global innovators,
he said. "The remaining lot have a secret desire to be taken over and
want to avoid any confrontation with a potential buyer," Mr Gulati said.
The provision of CL has been used in countries such as Thailand,
Brazil and South Africa. In all these nations the provision was used
for HIV medicines, the commerce ministry has said in its discussion
note. India has an estimated 2.3 million people living with HIV.
