db, Today's selling was almost all retail, and I think that much was profit taking. The big negative in yesterday's data was the final phase I/II data for Panretin. The delta is very close to that required for approval, and a failure to get approval would be LGND (ALRIZ) first stumble. The interim data was 30% vs 9% for a delta of 21%. The final data was 27% vs 16% for a delta of 11%. LGND (ALRIZ) felt that about 1/4 of the control lesions (untreated) showed evidence of treatment, so the true result would be 27% vs 12% for a delta of 15% which is what was required (but its still very close). The independent review of the controls indicates that they are at or below 10%, so assuming they don't change, a response from 25% or more of the patients would provide the necessary delta. LGND (ALRIZ) is increasing the population by 35 which I suspect will make the delta statistically significant which will add to the approval arguement and make the result publishable. I thnk LGND will come through, but I'm sure that many are uncomfortable with the latest data. I haven't had a chance to look at the early data and suspect that the response was slightly better at the more optimal concentration which would be used in the phase III study. It also would have been nice to have had the leptin deal done. When I made my original prediction in November, I thought that there was a good chance that at least one deal would be announced. Reuter's indicates that it will happen this month, but I'm sure many would like to see the terms. There were however, several pluses. I just looked at LGND's latest summary sheet, and ALRT256 isn't even listed. I had seen the earlier in vitro data, but it is encouraging that the in vitro data translates into two well established animal models (db/db and ob/ob) for diabetes and obesity (which is what db and ob stand for). The ALRT256 response was stronger than Targretin and its nice to have a well defined back-up (I suspect Targretin trials will happen first since it has already successfully completed phase I trials and is in several phase II or phase III trials). The anti-retinoids should also be interesting. Like anti-estrogens (Droloxifene, Raloxifene, Idoxifene, Tamoxifen, CP-366,156), these compounds may have several applications. The receptor specific retinoid also has obvious clinical indications with fewer side effects. Thus, there was a good deal of good news presented and I think that the sell-off is largely technical. Many short term traders have hopped aboard and moved the price very far very fast and many of the big boys missed the boat. Its not unusual for the MMs to work the price lower, so the big boys can hop aboard. Yesterday LGND's accumualtion distribution rating returned to "A", so there have obviously been many buyers lately. The ratcheting down of the price today has been due to burst of 1000 share trades and its hard to tell if they were buys or sells because they all happened at about the same time. Its hard to call the price that the big boys will come on board, but there was plenty of good news and much more to come, so I don't think they will miss the boat again and I expect the big boys to be the primary force behind a major upturn.
