Exact Sciences jumps by 30% on Cologuard deal with Pfizer. (22 Aug 2018) Shares of diagnostics and research firm Exact Sciences Corp (EXAS $37-$65-$72), maker of the Cologuard cancer screening test (and that cute little talking box from the commercials), surged 30% following the announcement that the company was teaming up with Pfizer (PFE) to promote DNA screening. Under the terms of the three-year deal, Pfizer will co-promote the Cologuard test beginning in the fourth quarter. In return, Exact Sciences will share a portion of the gross profits from the sale of the kits and pay some of the marketing expenses incurred. There are few things that a man over 50 wants to do less than get a colonoscopy, which is why this sort of DNA testing will continue to become increasingly popular. Shares of EXAS have been all over the place during the last few months, hitting a high of $71.60 in June, followed by a bottoming-out at $47.85 in early August, and then the current run-up to $65 today.

Former high-flying CEO of Theranos charged with massive fraud by SEC
(15 Mar 2018) She was on the cover of magazines and heralded as the new medical superstar; now, Theranos CEO Elizabeth Holmes, whose net worth was once touted at $4.5 billion, is worth zero (according to Forbes) and is being charged by the SEC with massive fraud. Holmes' blood-testing company seemed to offer a panacea: one simple blood test could predict a host of ailments from a simple drop of blood. The company had contracts with the likes of Walgreens (WBA), and the sky seemed to be the limit. Then, after one of the company's labs was uncovered for faking results, the roof caved in. The sad fact is, Holmes honestly believed in the work her company was doing, and her intelligence (she was a President's Scholar at Stanford) was never in question. The pressure to produce results, however, led the company to make the unforgivable choices. If they hadn't falsified the results and stretched the truth about a US military contract, they may not have attracted the same level of investment, but they would still be in business, and Ms. Holmes' net worth would not be zero. |

New Alzheimer's blood test could detect the disease decades before symptoms arise
(05 Mar 2018) While no cures or vaccines exist for Alzheimer's, a new blood test being developed could identify the disease's onset decades before an individual shows any symptoms. Last summer, researchers at Washington University in St. Louis completed a study showing that a simple blood test could identify the presence of a sticky protein, called amyloid beta, in the brain. An accumulation of these plaques in the brain is believed to be a major factor in the disease's formation and development. Two months ago, a joint Japanese/Australian team published a study about a blood test showing a 90% effectiveness rate in identifying the nefarious protein. The test uses mass spectrometry to detect the amyloid beta. The blood test would represent an enormous milestone on the road to eliminating the disease. |

Researchers working on a $500 blood test which could detect eight types of cancer before symptoms arise
(23 Jan 2018) A group of scientists and researchers led by a team at Johns Hopkins School of Medicine are working on a revolutionary new blood test which could identify eight different types of cancer before any symptoms have become evident. The new blood test, called CancerSEEK, would cost just $500 and would look for target cells from lung, breast, ovarian, and colorectal cancers, among others. While the test has proven very effective on a study group of over 1,000 volunteers known to have a form of the disease, it also effectively ruled out nearly the same number of healthy individuals. In other words, the rate of "false positives" were much lower using CancerSEEK as compared to conventional detection methods. For five of the eight types of cancer detected by CancerSEEK, there are currently no screening tests available. The next step? A new, large-scale trial using up to 10,000 healthy individuals. If this trial goes as expected, CancerSEEK will be well on its way to becoming commercially available. For more information, visit Johns Hopkins School of Medicine. |
