Even Bloomberg admits: China’s Curing Cancer Faster and Cheaper Than Anywhere Else
Zhang Haitao was a basketball-loving teenager who dreamed of going to a specialized sports high school when he got a pain in his right arm that just wouldn’t go away. It turned out to be acute lymphoblastic leukemia.
The discovery set Zhang and his family, from a village deep in the mountains of southwestern China's Sichuan province, on a journey familiar to most cancer patients — a revolving door of hospital visits, blood tests and three rounds of chemotherapy. It was then that Zhang’s doctor suggested a last-ditch option: an experimental gene therapy being trialed by a Chinese startup called Gracell Biotechnology Ltd.
After spending three weeks in the hospital in May — during which white blood cells were removed from his body, genetically engineered, and then infused back in — an analysis of Zhang’s bone marrow in June showed his body was clear of cancer.

Seven months later, monthly medical tests conducted at a hospital in the nearby Chinese metropolis of Chongqing show he remains cancer free.
“I don’t remember much about the treatment as I had a fever throughout,” said Zhang, who’s now almost 16 and spends his days playing video games and texting his friends. “It seems like a new solution that will give people hope.”

The therapy Zhang received was Chimeric Antigen Receptor-T cells, known as CAR-T, and it’s being hailed as one of the most exciting developments in the quest to cure cancer. First developed by Israeli scientist Zelig Eshhar in the 1980s, CAR-T re-works the genes of the body’s own immune cells so that they actively seek out and destroy cancer cells. While it’s been embraced by researchers and drugmakers around the world, perhaps nowhere is CAR-T having more impact — and being pushed dangerously close to its limits — than in China, home to the world’s biggest cancer population and some of the most ambitious experiments.
How CAR-T Works
CAR-T works by supercharging T-cells, the body’s main line of defense against disease, so that they latch onto and destroy cancer. In clinical trials, leukemia patients who failed to respond to other therapies have shown remission rates of over 90% within two months of treatment.
Though drug giants Novartis AG and Gilead Sciences Inc. have been marketing CAR-T globally since 2017, it’s expensive. The process of engineering an individual’s cells in a laboratory and then replicating them has also meant that some patients with more aggressive cancers can die waiting for treatment.
That’s where Gracell’s therapy was revolutionary. Instead of the two to three weeks taken by current treatments from American and European drug makers, the Shanghai-based company — set up by a group of veteran Chinese cell-therapy researchers — is churning out cancer-killing immune cells overnight.
And they’re doing it much cheaper in some cases than global pharmaceutical giants. Gracell has developed a process using genetic engineering that speeds up the cell production stage, according to founder William Cao Wei. Gracell plans to price its CAR-T treatment for about 500,000 yuan ($71,000), well below the $475,000 price tag for Novartis’ Kymriah, the Swiss company’s CAR-T therapy used to treat the type of blood cancer that Zhang had. A similar treatment from Gilead, based in Foster City, California, costs $373,000.
The aging population and a raft of lifestyle factors mean that more new cancer patients are emerging in China than anyplace else in the world, giving the country a significant stake in the global fight to find a cure. Emboldened by the government’s push to become a scientific superpower and to dominate the field of genetics, Gracell and other Chinese biotech startups are racing ahead, with China likely to approve CAR-T for widespread use as early as next year. Up for grabs is a market for cancer drugs and experimental treatments that has exploded to $133 billion a year worldwide, according to life sciences researcher Iqvia Institute.
“There can be both cooperation and competition between us and CAR-T developers in developed markets,” said Cao, who is also Gracell’s chief executive officer. “But there will definitely be competition.”
