I can't ascertain the status of PRE-084. Is it one of the approved treatments? Someone will know, I didn't dig too deep. I did find this interesting tidbit:
"Our first data obtained with PRE-084 provide a useful tool to screen other potential clinical candidates with agonistic activity at the Sig-1R. Indeed, comparing the effects given by sev - eral doses of different Sig-1R agonists with the ones shown by the effective dose of PRE-084 will help to find the therapeutic window of the tested compounds. In the last years several studies also reported anti-amnesic and neuroprotective effects of Sig-1R ligands in animal models of AD (Maurice and Su, 2009). Clinical trials in patients with AD are now ongoing (further informations can be found at www.anavex.com), and the aim for the future is to accelerate the steps from preclinical to clinical trials also on PD patients." http://lup.lub.lu.se/luur/download?func=downloadFile&recordOId=4944782&fileOId=7616470 §AVXL
