As I understand it, researchers have determined that they can "distill" a concoction that seems to neutralize the CALR mutation. I assume that these tests have been conducted at the cellular level and not in living organisms, but not a lot of info is available in the article's abstract.
At the risk of being the crochety old lady that I am, let me rain on this parade momentarily. It takes drugs years to crawl through the FDA from this initial research stage before they are approved for use. And we know from countless other examples, such as Jakafi, that cures and new drug treatments are not going to come cheap. Jakafi costs over $10k per month. People I've spoken to who are on it love it. But it can stop working without warning. And it's not yet approved for ET, thus many insurance companies won't pay for it.
So at 63, I don't expect to see a cure in my Future and if there is, I doubt I'll be able to afford it. What I WOULD like to see is better palliative care for the Right Now.
