I can completely understand why some people take the view that they'd rather not spend money confirming a disease they don't want to have and for which there is no cure. But I think there are a few aspects that those used to selling a therapeutic may have overlooked.
Firstly, patients for whom Amyvid is relevant are symptomatic. They have something wrong with them which is what motivates them (or their loved one) to seek a consultation. Whether it's Alzheimer's, another form of dementia or some other condition, the physician will start up a diagnostic workup. The news is already likely not to be good. In this situation the patient, caregiver AND physician are looking for more information, a differential diagnosis and a strategy for a likely chronic condition. By this time, ignoring the problem and hoping it's not something bad, is unwise. If you picture yourself in the unenviable position of those experiencing dementia-like symptoms or, like most people who frequent this board, a close relative with these symptoms, you have a sense of urgency about getting an accurate read on the disease. This isn't 100% but it is a lot better than clinical diagnosis alone in some cases. Which brings me to the other reason why this test is a breakthrough:
Whilst Amyvid is not an appropriate test for people who are asymptomatic (yet), for people who present, a proportion will be told that there are no neuritic amyloid plaques and will not have to face Aricept or Namenda and may even have a condition which is not chronic and uncurable. This will be a significant minority and the costs of inappropriate treatment, side effects and unecessary hospitalization for this group will be reduced. Think about it. That is why diagnosis is an important function of our physician and why they do more than "go on a hunch"
According to the literature I have read on Amyvid since we acquired it, the proportion of patients inaccurately diagnosed, based on current expert clinical diagnostic accuracy is up to 1 in 4. In the primary care world where many people are currently diagnosed this could be over a third. This test, combined with clinical review is bound to make a hell of a difference in these cases.
I am not normally swept up by the hype that accompanies our acquisitions. They are often accompanied by broad sweeping language and optimism that is misplaced. But this one may be different. By getting all of us from R&D through to sales and marketing, to look at the healthcare business beyond the next therapeutic tweak, we can potentially catch up with where modern healthcare needs to go. I don't think this will "save Lilly" commercially, but I think as a strategic play it was a bold move and as an aid to the humanitarian crisis which Dementia presents, it is something I as a nearly 20 year Lilly veteran, am proud of.
Good luck to the AD team!
