$PRTA Is there data readout before December 20? I ask this because I noticed something strange and peculiar with the December options.

$PRTA when do we anticipate data release for birtamimab in stage IV amyloidosis? Bit skeptical of company due to issues with prasinezumab.

User Image barlaw Posted - 1 month ago

$SAVA So how ‘bout this guy Dr. Masilah? Runs Neuroscience at NIA/NIH for many years, in charge of billions of research $s and directing drug development to his areas of interest. He’s now accused of fraud in scores of papers over many years — in the AD/PD spaces, mostly about MABS and alpha synuclein. So Prothena ($PRTA) only gets their feathers ruffled a bit when the Science article comes out 9/27. Their P2 drug is the one most closely spawned from Masilah’s tainted tenure (he was just fired), and it hasn’t even shown much promise. So while Wang’s misdeeds pale in comparison to Masilah’s, the therapeutic candidate Simufilam is brutalized by organized short/distort efforts for years. It’s sure hard to come away with the notion that Simu is destined to be a fail when you compare these two market reactions to research misconduct. But oh, PRTA has a BP sponsor, so it’s apples and oranges. Make no mistake, Simu is seen as a massive threat to the status quo, that being: “BP rules”.

$PRTA Prothena's prasinezumab linked to apparently huge fraud. The real reason for the CMO to leave? Prasinezumab worthless? https://www.science.org/content/article/research-misconduct-finding-neuroscientist-eliezer-masliah-papers-under-suspicion
