Biocon has scored an early win among its peers with the UK approval for the first generic version of liraglutide injectible, which is losing patent protection in November. The weight loss drug, sold under the brand name Saxenda by patent holder Novo Nordisk A/S, is among the first of the groundbreaking medications in this category to lose patent protection.

While Saxenda is far less effective for weight loss than later iterations like Wegovy and Ozempic, its generic version is just the beginning of a jackpot that drugmakers like Biocon are awaiting. “My leadership team and organisation is ensuring that we do not give up the lead position we have now,” CEO Siddharth Mittal said in an interview.

Another 15 peptide formulations are under development, of which one or two drugs will seek regulatory approval this year, he said. Biocon has also filed applications before the US and European regulators for liraglutide.

The company, helmed by Kiran Mazumdar Shaw, is leading the charge among Indian drugmakers — the world’s largest supplier of generic medicines — as they race to grab a slice of the obesity drugs market. The global frenzy around these medicines has already lured sector giants Sun Pharmaceutical Industries, Dr. Reddy’s Laboratories Ltd., and Cipla, who are also developing their anti-obesity drugs.

Weight loss drugs have already produced record profit for innovative pharmaceutical companies from Novo Nordisk to Eli Lilly & Co. The gold rush is set to spread to generic makers like India’s biggest players when patents expire in the coming years on Ozempic and Wegovy, allowing cheaper copies of the medication to flood the market and plug supply gaps.

Novo Nordisk’s Ozempic and Wegovy are made with the same active ingredient, semaglutide, while Eli Lilly’s tirzepatide drug is sold as Zepbound. These, along with liraglutide, are part of a class of medications called glucagon-like peptide 1, or GLP-1, agonists.

Biocon is building capability “to take advantage of what could be a very, very strategic peptide opportunity with GLPs at the centre,” group CEO Peter Bains told analysts in November. 

‘Very complementary’

The loss of exclusivity for GLPs will create a multibillion dollar market over the next 10 years and this opportunity was “very complementary” to Biocon’s current biologics business, according to Bains.

In the UK, Mittal said the company will wait for the publicly-funded, National Health Services, to float a tender to launch its liraglutide injectible. Biocon’s UK application was filed through its European partner, Zentiva SA. The total addressable UK market opportunity for GLP-1 in diabetes and weight loss is $425-million, according to a statement on 27 March by Biocon.

Despite the weight-loss segment being a rage globally, these drugs are yet to make a wide scale appearance in India whose 1.4 billion-plus population is rapidly getting more affluent and obese.

Novo Nordisk, which only sells its semaglutide-based pill Rybelsus in India, is planning to introduce injectables Wegovy and Ozempic in 2026, Reuters reported in February. Eli Lilly is conducting clinical trials in India for weight-loss pill, orforglipron. 

Biocon has not yet filed for liraglutide approval in India and it is working with the local drug regulators to see if the requirement of a clinical trials can be waived, Mittal said. The company is also looking for a partner to market its obesity drugs in India after it sold its branded formulations business to Eris Lifesciences Ltd. last month.

Over the next 20 years, “this is a very attractive space”, Mittal said. The UK approval shows that Biocon can confidently “capture the opportunity in the coming years”.
