Here are some important updates on the Herceptin in India. As I previously reported in my blog about facts about divisional patent applications viz. 3272/KOLNP/2008 and 3273/KOLNP/2008 rejection and negative hype by media.
Now interestingly the basic patent IN205534 on which above divisional are based is lapsed because of non-payment of annuity fees as of 03.05.2013. However Section 53 of the Patents Act reads with Rule 80 allows the Patentee to pay the same within the extended period not more than six months, if the request for such extension of time is made in Form-4. But this request should be made before the expiry of last date of renewal ie 03.05.2013. Patentee still can restore the patent under Rule 60, but patentee has to be able to give the Patent Office a good enough reason to allow the restoration application. Already this patent is under post grant opposition filed by Glenmark. So it seems quite difficult path ahead for Genentech if they wish to restore the patent because Glenmark most likely to oppose the restoration.
And Roche (Genentech) said that it has no plans to seek a restoration of the patent. The decision to let the patent lapse was part of a new strategy it wants to follow in the local market for the high-value biological drug. “Regular reviews of our patent portfolio are a routine business practice. In this connection, Roche has come to the conclusion not to pursue Indian patent for trastuzumab”.
Herceptin contributes close to Rs 127 crore to Roche’s annual turnover, according to industry estimates. Roche’s decision of giving up its patent is a smart move, say IP experts as there is no Indian company manufacturing this drug due to the complex science involved. So, even after giving up the patent, Roche will be the only company that will be manufacturing this drug, and the company knows it. While the patent for Trastuzumab may no longer be in force, it is important to note that there are currently no approved biosimilars of Trastuzumab in India.
But latest news about Biocon launching the biosimilar of Herceptin could change the game. As announced by Ms. Shaw, Biosimilar version is in phase III studies and they intend to launch in India by end of March 2014. She has not disclosed the price but it would be much cheaper than the current price of Herceptin in India. Herceptin’s price, at around Rs 1 lakh a vial in 2011, was lowered to Rs 92,000 last year and then further Rs 72,000. Treatment cost with Herceptin may be reduced to about half with the launch of the drug’s cheaper version
Apart from Biocon, two other Indian firms, namely Dr. Reddy’s Laboratories and Intas Pharmaceuticals are planning to launch their own version of Herceptin biosimilars.
