$PRTA The U.S. FDA has granted Fast Track designation to Bristol Myers Squibb's (NYSE:BMY) BMS-986446, an anti-microtubule binding region-tau (anti-MTBR-tau) antibody in phase 2 for early Alzheimer's disease. The drugmaker said that in preclinical models, the asset led to major reductions in tau uptake and spread, as well as protection against behavioral deficits. "By neutralizing the spread and promoting the clearance of pathological tau, BMS-986446 aims to modify the underlying course of the disease with the ultimate goal of slowing or delaying disease progression," Bristol said in a news release. Bristol is partnered with Prothena (PRTA) on BMS-986446.

$PRTA Idiot bears who kept on saying “CMO resigned” is a bad sign. But they do not understand that the company wants to sell to the highest bidder once all its PD and AD drug candidate concepts are proven. It will be hovering about $10 for some time then will be sold for $2B + ($40 per share), IMHO. I have been saying this for 9 momths now. What is PD and AD market worth? Everyone is getting old and about 1/4 will develop the horrible diseases. 🔥🚀🔥🚀🔥🚀🔥🚀🔥🚀🔥🚀🔥
