Oliver Sacks has terminal cancer. If you have not yet read his heart-warming Op-Ed piece in the New York Times and if you only have five-minutes to spare, then I suggest you read his essay rather than this blog about “experiments of nature” in drug discovery. In his essay, Dr. Sacks concludes with the poignant sentence: “Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and adventure.

Why do I start this week’s blog about articles of the week with this reference? I do so because of two additional – and seemingly unrelated – items from this week: (1) a brief Twitter exchange with David Shaywitz, Derek Lowe, and others that “few people at public biopharmas write interesting stuff, vs consultant-and-PR-driven banality”; and (2) an article in the New York Times Magazine about how Twitter posts can get you into trouble with your employer (see here).

So why do I blog, tweet, etc. given the potential risk? I enjoy the public exchange of ideas because, as Dr. Sacks write, that is the essence of our “sentient being”. I enjoy a network of inter-related ideas for which I can create unique connections.…

I have had many of my non-genetic physician colleagues comment to me: “We practice personalized medicine every day.  It’s called basic patient care!”  Their point: physicians see patients and make decisions about the best course of treatment based on patient preferences.  For example, one RA patient may prefer to have a drug infusion once per month and another patient may prefer to take a pill each day. 

The Nature Medicine article emphasizes  “the idea that molecular information improves the precision with which patients are categorized and treated“.  While personalized medicine might say “patient X with disease Y should get drug Z”, precision medicine says “patient X has a subset of disease Y — actually, disease Y3, not disease Y1, Y2 or Y4 — and patients with disease Y tend to respond more favorably to drug Z”.  Said another way bt Charles Sawyers, an oncologist at the Memorial Sloan-Kettering Cancer Center in New York: “we are trying to convey a more precise classification of disease into subgroups that in the past have been lumped together because there wasn’t a clear way to discriminate between them“.…
