Thanks for the report on the annual meeting. The most important facts that you report are the responses on the Neuropathic Pain trial. These are important because this is the indication that will produce the greatest revenues for NTII. In addition, these results are really encouraging. The pretreatment pain levels are substantially higher in this Phase IIB trial than occurred in the earlier Phase II trial (60 vs. 45 on the 100 point scale). So, prior to treatment, the patients in the Phase IIB trial are suffering to a greater extent than in the first trial. Yet, the response to memantine is to reduce pain to a comparable level (mid 30s). This is a very significant reduction in pain level; cutting it virtually in half. This level of reduction is beyond what one might expect for a placebo effect. So, it strongly suggests that memantine is working well to relieve their suffering. The magnitude of the effect is important because it indicates that the results may not only be statistically significant, but also clinically significant. In the long run, after approval, this translates into marketability. If I were a Neuropathic Pain sufferer, I would surely want to be taking a medication that could cut my pain in half and let me rest at night. That level of comfort would be worth quite a lot to me. Today was another good day for NTII stock price. I was expecting a small pullback from the 2 1/2 level as usually occurs after a nice run up. But, instead it continues its rise on high volume. It's movement is very impressive and these Phase IIB results may be the main reason for the strength. Best regards John de C
