A new cancer drug known as BLU-667 has moved through phase I human trials, and the results are promising. Taken orally, the drug targets what are known as RET-driven cancers, including types of thyroid and lung cancers, which are normally hard to treat.

RET is a type of receptor tyrosine kinase, and mutations that kick its activity into overdrive are linked to certain kinds of cancer. Among others, RET plays a role in around 50 percent of medullary thyroid cancers, 20 percent of papillary thyroid cancers, and up to two percent of non-small cell lung cancers. These can be treated with conventional methods, although so far success hasn't been stellar.

"There is a critical un-met need for effective drugs against cancers that have the RET alteration, as there are no highly potent inhibitors currently approved specifically for these RET-driven cancers," says Vivek Subbiah, lead researcher on the study. "The current treatments for these cancers are limited to traditional chemotherapy and earlier generations of multiple kinase inhibitors. These options have had limited success with often considerable side effects that significantly impact the patient's quality of life."

BLU-667 works by inhibiting the activity of RET, and it was chosen for further study after it was found to be 100 times more selective for RET, meaning it shouldn't affect the functions of other kinases. It's also been shown to prevent certain genetic mutations that may allow the body to resist this kind of treatment.

For this trial, the team studied 43 patients with advanced tumors that weren't able to be operated on, as well as 26 patients with medullary thyroid cancer, 15 with non-small cell lung cancer, and two with other RET-related cancers. The results were promising, with the researchers saying that BLU-667 seems to be effective and safe for use.

"Tumor reductions and durable responses were observed in most patients, especially those patients whose cancer progressed with chemotherapy and multi-kinase inhibitors," says Subbiah. "Our study reported an overall response rate of 37 percent for RET-driven cancers, with responses of 45 percent for non-small cell lung cancer and 32 percent for medullary thyroid."

The results of the trial were published in the journal Cancer Discovery, and presented at the American Association for Cancer Research Annual Meeting 2018 over the weekend.

In a decade we'll have cancer cured with a pill. Go science!
Looks promising, can only get better from here.
That's great, but it's only a stage one trial. It has some way to go before it 'aces' anything.
Isn't this the premise of the "28 days later" movie? Beside there are Already multiple way to cure cancers... but none that the pharmaceutical industry can profit from and control. "Run from the Cure" Rick Simpson on Youtube is just One example.
If it really works, do you think you would actually hear about it?

Cancer will never be cured. The entire industry is a giant parasitic organism that thrives on having countless charities and events driven around it. What do you think an industry with millions of practitioners are going to do when their biggest cash cows are gone? A typical oncologist who prescribes chemotherapy today makes about $4000 USD per session. The other 6K goes to Glaxo the largest producer of chemo drugs on the planet. I know a doctor with more than 100 patients undergoing chemo sessions doing 1 session a week for six weeks. Do the math.
Jogun-- Beside there are Already multiple way to cure cancers OK, name them- give some links. Rocky Stefano-- Conspiracy theory. Better hope you never get cancer as you don't believe in medical treatments...
