“When the generics come in there will be a huge price war,” he said. “There is a huge demand for these drugs at the right price.”
In the US, Israeli drugmaker Teva in June launched a generic version of Victoza, a Novo Nordisk diabetes drug based on liraglutide, the same active ingredient as Saxenda.
The introduction of generic versions of Saxenda could prove a “dry run for semaglutide”, the active ingredient in Ozempic and Wegovy, said Christopher Sharp, an intellectual property lawyer at Pinsent Masons.
Sharp said there was likely to be strong competition from generics companies interested in developing GLP-1s “because the prize is so high”.
Biocon and other large Indian generic producers including Cipla, Dr Reddy’s, and Sun Pharmaceuticals Industries have been eagerly awaiting the erosion of Novo Nordisk’s exclusivity on GLP-1s.
The Danish company’s patents for semaglutide, the active ingredient in its blockbuster weekly Ozempic and Wegovy treatments, will begin to expire across Asia, Africa and the Americas from 2026 and from 2030 in the US.
Wegovy and Ozempic powered Novo Nordisk to record sales in 2023.
The global market in GLP-1s is expected to grow to over $140 billion ($229.7b) by 2030 from under $40b in 2023, according to GlobalData, a data provider.
Experts say entry of generic competition can typically result in a loss of around 80% of the market share of the original supplier, and falls in drug prices of about 20-30%.
Novo Nordisk’s sales of Saxenda are already down 36% in the first half of 2024.
The drug must be injected daily and is less effective than once-weekly treatments such as Wegovy and rival Eli Lilly’s Mounjaro.
Novo Nordisk declined to comment. The Danish company is currently focused on increasing supply of semaglutide to meet runaway demand in the US and existing markets and to introduce it to new countries.
“They don’t have enough manufacturing capacity,” said Prashant Nair, director at Mumbai-based Ambit Capital. “[That] is something Indian companies can provide and if that happens then India and other emerging markets can open up.”
India is expected to be a core driver of GLP-1 sales for the country’s generic drug sector, the world’s biggest.
The World Health Organisation estimates 77m Indian adults suffer from type 2 diabetes and government health surveys show almost one in four are overweight or obese.
India’s government has also announced it will subsidise the manufacturing of diabetes and weight-loss treatments once the patent for semaglutide expires in the country in 2026.
“There’s been some government push,” said Joydeep Ghosh, a partner at Deloitte India.
“There are several serious large-sized Indian generics players who are well-positioned even now.”
Srikanth Mahadevan, a director at Deloitte focused on healthcare, said sales of weight-loss drugs in India were estimated to be just a tenth of those in the US, but that would change once the country introduced semaglutide treatments.
India was going to be a “huge market given how big the patient base is”, Mahadevan said.
