00:00Today on Forbes, meet India's self-made biologics brewmaster billionaire.
00:07Kieran Mazumdar Shah's booming drug business started not in a laboratory, but in a tin-roofed shed in Bangaluru,
00:15the city formerly known as Bangalore, and the capital of the southern Indian state of Karnataka.
00:21Inside, the 25-year-old was using the knowledge she had learned studying beer brewing in Australia
00:26to ferment enzymes for customers like Ocean Spray Cranberry Juice.
00:31Originally, she had wanted to be like her father, who was the head brewmaster at United Breweries,
00:36the big Indian firm now owned by Heineken and famous for its Kingfisher beer.
00:41But it was 1978, and she couldn't find a job. No one wanted to hire a woman as a brewer.
00:48Distraught and disillusioned, Mazumdar Shah put her education to another use, making enzymes for industrial uses.
00:55In partnership with an Irish entrepreneur who owned a company called Biocon,
01:00and who was looking to expand to India, she set up shop inside that hot shed.
01:05She says, quote,
01:06I call myself an accidental entrepreneur.
01:10The business became successful enough that Unilever bought it in the 1980s,
01:14along with its Irish parent.
01:16Mazumdar Shah stayed on to run the unit from Bangaluru until 1998,
01:21when she and her late husband, John Shaw, bought back Unilever's steak for about $2 million.
01:27It was a steal.
01:28She would eventually sell the enzymes business to Denmark's Novozymes for $115 million in 2007.
01:35By then, she had bigger things in mind.
01:38In 2000, Biocon began brewing up pharmaceuticals, starting with insulin.
01:43Insulin is a type of so-called biologic, or a drug derived from a living source.
01:49Traditionally, a modified version of E. coli bacteria in insulin's case.
01:54Biocon uses yeast.
01:56The company's India base enabled it to make these biologics cheaper than big western pharma outfits.
02:02Insulin is one of the simplest biologics,
02:05which are increasingly used to treat everything from cancer to immune system disorders.
02:09More complicated biologics like gene therapies and monoclonal antibodies are difficult to make,
02:16and extremely expensive.
02:18One drug for children with spinal muscular atrophy, for instance,
02:21costs more than $2 million for the one-dose treatment.
02:25It's an enormous market, but exactly how big is impossible to say.
02:30Biologics accounted for $324 billion in spending at list prices in 2023,
02:36according to healthcare research firm IQVIA.
02:39But that number doesn't account for the significant rebates
02:42that branded drug makers often offer to keep their market share,
02:46lowering what insurers and patients pay, but obfuscating total costs.
02:51While a butler serves tea at her Manhattan apartment,
02:54which is adorned with landscapes by Scottish artists George Devlin and Archie Forrest,
02:59Mazumdar Shah says,
03:01These are very complex, expensive drugs,
03:04and therefore it's important that companies like ours focus on affordable access.
03:10Mazumdar Shah, now 72 years old,
03:13started out in the Indian market, but now sells drugs globally,
03:16and is increasingly focused on the US and Canada,
03:19which represents some 40% of its biologic sales.
03:23She realized early that finding a cheaper way to make such complex,
03:26life-saving drugs not only made them more accessible, but was also good business.
03:32Today, Biocon, which is publicly traded in India,
03:36brings in $1.9 billion in revenue by selling dozens of generic drugs and so-called biosimilar medications.
03:44The company also does contract research for other companies through its publicly traded subsidiary, Syngine.
03:49While Forbes' self-made women list includes only women from the United States,
03:55Mazumdar Shah would easily make the top 20 were she American.
03:59She is one of the world's wealthiest self-made female entrepreneurs,
04:03with a fortune that Forbes estimates to be $3.2 billion.
04:08The biggest part of her empire is a majority-owned private subsidiary called Biocon Biologics,
04:13which focuses on biosimilars and represents nearly 55% of the parent company's revenue.
04:20Akin to what generics are for chemically synthesized drugs,
04:23these cheaper alternatives mimic biologic drugs.
04:27As with generics, companies like Mazumdar Shah's are allowed to develop biosimilars
04:31after a brand-name drug's patents expire.
04:35Though biosimilars are much more expensive to make than generics,
04:39requiring more than $100 million to develop,
04:41they can drastically reduce patient costs.
04:45IQVIA estimates biosimilars have saved the U.S. healthcare system
04:48$36 billion at list prices since 2015.
04:53With 118 more biologic drugs set to lose patent protection by 2035,
04:59the market for their cheaper mimics could be about to boom.
