Memory Pharma extended it's gains from Monday today on news that it's leading Alzheimer's drug candidate MEM1003. MEMY is trading up in late afternoon action 47 cents a share (thats up almost 20%) at $2.83. Monday MEMY traded up over 44%. The company has fully enrolled it's phase IIa clinical trial for MEM1003 which means a, they found enough people to run the study with mild to moderate disease; b, it tells investors that the company has confidence in the drug and will rather quickly know whether or not there is efficacy.
MEM1003 is a drug that targets L-type calcium channels in patients with Alzheimer's. Ongoing research strongly suggests that aging alters brain Ca2+ regulation, resulting in impaired neuronal function and, eventually, neurodegeneration.
Voltage-dependent Ca2+ currents and potentials are enhanced in neurons of aged experimental animals, and apparently are mediated by an increase in the membrane density of L-type voltage-sensitive Ca2+ channels. In addition, selective L-VSCC antagonists and other Ca2+ blockers can counteract the effects of aging on several aspects of neuronal and/or behavioral function, implying that channel activity may be necessary for the aging changes.
MEM1003 selectively blocks these channels and could help regulate calcium flow.
