It involves using cells from his own immune system

Cancer Treatment With Gene Editing Underway

Canada Goose sale Shaorong Deng is sitting up in bed at the Hangzhou Cancer Hospital waiting for his doctor. Thin and frail, the 53 year old construction worker’s coat drapes around his shoulders to protect against the chilly air. Canada Goose sale

Deng has advanced cancer of the esophagus, a common form of cancer in China. canada goose uk outlet He went through radiation and chemotherapy, but the cancer kept spreading.

Now he’s back at the hospital to get an experimental treatment. It involves using cells from his own immune system, known as T cells, after they have been taken out of his body and genetically altered in a lab by the gene editing tool called CRISPR.

Canada Goose online «I consider canada goose coats myself very lucky,» Deng says through an interpreter as a nurse finishes taking his blood pressure. Canada Goose online

Just then, the door swings open, and the nurse canada goose uk black friday rushes back in. She’s cradling a clear plastic pouch filled with yellowish fluid. She hangs the pouch above Deng’s bed, attaches one end of an intravenous tube to the bottom, and slides a Canada Goose online long needle at the other end into Deng’s arm.

Deng stares at the IV as millions of genetically modified immune system cells slowly drip into his body. The infusion will take at least an hour.

canada goose coats «I Canada Goose Coats On Sale can only hope it will completely completely get rid of the cancer,» Deng says. canada goose coats

Deng is participating in what Wu says is the most advanced study in China testing CRISPR in sick people. government

canada goose deals In contrast, only one CRISPR cancer study has been approved in the United buy canada goose jacket cheap States, and it’s only just now starting to look for the first patient to treat. canada goose deals

canada goose clearance sale «China is starting to pull ahead of other parts of the world maybe for the time in regards to biomedicine,» says Hallam Stevens, an anthropologist at the Nanyang Technological University in Singapore who studies Chinese bioscience. «They’ve been really investing heavily in it over the last couple of decades and canada goose store it’s starting to pay off in a uk canada goose outlet big way.» canada goose clearance sale

canada goose black friday sale The treatment Wu is testing involves taking a sample of blood from each patient. A lab at a biotech company two hours away buy canada goose jacket by bullet train extracts T cells from the blood. Scientists then use CRISPR to knock out a gene in the T cells known as PD 1. This engineering feat modifies the T cells so that they Canada Goose Online zero in on and uk canada goose attack the cancer cells, once they’re infused back into each patient. canada goose black friday sale

Deng was returning to the hospital to receive his second infusion of gene edited T cells. When he first arrived canada goose outlet at the hospital about a month ago, he was so weak he needed a wheelchair. But Deng says he started feeling cheap Canada Goose better soon after his first infusion.

Canada Goose Jackets «I feel very stable,» Deng says. «I was weak in the limbs canada goose factory sale before and now I am not weak anymore.» Canada Goose Jackets

buy canada goose jacket cheap It’s still too early to draw firm conclusions about how effective the treatment will be or what the full extent of side effects from it. Deng is one of just 21 patients with advanced, incurable cancer canada goose uk shop of the esophagus that Wu has treated so far with CRISPR edited T cells. buy canada goose jacket cheap

But Wu says about 40 percent of the patients appear to have responded. One patient is still alive almost a year later.

There’s no randomized comparison group in this study. But usually, such patients would have no cheap canada goose uk hope, Wu says. «If they have not received this treatment they will die most of them will die in three to six months,» he says.

canada goose coats on sale Wu says he’s writing up the results for Canada Goose Outlet a scientific publication, but these results have not yet been peer reviewed or published. canada goose coats on sale

So far, Wu says the only side effects have canada goose clearance been mostly minor an occasional fever or rash. Nine patients in the study have died, but Wu says that was from their cancer, not the treatment. One patient discontinued treatment because of a high fever. The rest appear to be stable or in «partial remission,» Wu says. They are undergoing monthly treatments.

«As a cancer doctor, you see many deaths,» Wu says. «So it’s good to be part of this.»

«China sees biomedicine as one way it canada goose black friday sale can compete with the West and show off its technological prowess and scientific chops in the 21st century,» Stevens says. «It’s also something that’s Canada Goose Parka going to be critical for keeping China’s population healthy in the 21st century.»

Less skeptical about science

canada goose In general, medical research in China isn’t as stringently regulated as in the West, Stevens says. «It begins at a different starting point,» he says. canada goose

canada goose store In the West, there is a history of awareness about the dangers of medical experimentation run wild, he says, going back to the Nazi era and also the notorious syphilis study at Tuskegee University in Alabama, where doctors withheld treatment from black men for decades. canada goose store

buy canada goose jacket «Rather than having the starting point being: ‘This could be dangerous or this could be risky for people and we need to take that concern uppermost,’ » Stevens says. «They start with the canada goose coats on sale premise: ‘This is going to be beneficial for China.’ » buy canada goose jacket

Canada Goose Outlet Wu says his study was allowed to Canada Goose sale begin after being approved by a Canada Goose Jackets single nine member hospital committee in just two months. He says the committee included a lawyer, a bioethicist, nurses, doctors, a journalist, a representative of cancer patients and a representative of the public. Canada Goose Outlet

canada goose clearance «Chinese patients want to be cured very much,» Wu says. «There’s a Chinese saying: A living dog is better than a dead lion. So patients are willing to try new cures. That’s why the ethics committee and the lab are very positive about this.» canada goose clearance

But the less stringent oversight makes doctors and bioethicists worry that some Chinese doctors may be rushing ahead too quickly, possibly putting patients at canadian goose jacket risk.

canadian goose jacket «My concern is: Are we really ready? There so much about CRISPR that we don’t understand,» says Lainie Ross, a bioethicist at the University of Chicago. «We could be doing more harm than benefit. We need to very, very cautious. This an incredibly powerful tool.» canadian goose jacket

Canada Goose Parka Ross noted that there are already drugs available that work that harness the immune system in the same way as Wu is trying to use CRISPR Canada Goose Parka.
