I can't believe PH hasn't posted a message yet telling us ERX will close above .0040 Today & to get in before it's to late.(still looking good so far this morning)

He will be over from the Dark side soon Marcel probably to tell us News on the 22nd !! but yes a little tic up this morning :)

smiler,he is and he is right about the date.

read an article while i went out for a coffee, they reckon cause holiday period is coming a lot of stocks will rise, some very sharply

hmmm!!! hope so

rising fast...

Come on PH your off on your party soon and then the sp can shoot up!

good to see this one moving up ahead of results next week.

Hopefully gardyne our patience will be rewarded Some time next week !!

I think we should do well as we are just about back where we were a couple of weeks ago, it would be nice to see it steaderly rise until next friday.

Bid was just at 0.35p when Offer price was only 0.33p work that out?
Must be very keen to get people to sell last thing! IMO.

Nice tick up again today,That 3 In a Row hopefully 4 Monday.

lets see what they say on friday eh!!

a bit worrying that they want to release on the quietest trading day of the year.

or maybe it will be a christmas present

I can do with as well after the bad news i received this weeked

Some serious tree shaking going on!

dont know why laurie, another 4 days to go before news, and I bet we dont get the news until mid-day on friday rather than 7am

Can't understand the slight drop as the 00.0030 are buys

MMs want cheap shares! Seeing if any panic sellers.

If thats the case it has had the oppersite affect as them seems be more people buying than selling

there are some shorters, SCAP and HOODS, althou, I think HOODS have reduced there short position on friday and will close the remaining shorts during the course of this week. SCAPS I think will close at the last minute which could see us SPIKE quite sharply

this is why we went so much on friday, this was published friday

Avalon Pharmaceuticals, Inc. (NASDAQ and NYSE Arca: AVRX), presented a poster detailing the effect of AVN944 on a comprehensive set of genetic and biochemical biomarkers at the American Society of Hematology 48th Annual Meeting. AVN944 demonstrated a statistically meaningful impact on IMPDH and other proteins that are critical to activities in cancer cells, including nucleotide biosynthesis, energy and metabolism, DNA replication, apoptosis and cell cycle control. The data were collected in an ongoing Phase I open-label, repeat dose-escalation study designed to evaluate the safety and tolerability of AVN944 in patients with advanced hematologic malignancies and to determine the optimal dose for Phase II efficacy trials. Further data from an interim analysis of the trial is expected to be available shortly.

"IMPDH is highly upregulated in most hematological cancers and in many solid tumors," said Beverly S. Mitchell, M.D., Deputy Director of the Stanford Comprehensive Cancer Center and George E. Becker Professor of Medicine at Stanford University. "IMPDH plays an essential role in cancer cell synthesis of DNA and RNA, and the inhibition of IMPDH represents a new and potentially important approach to the treatment of cancer."

Analysis of the selected markers in patient samples from the Phase I trial showed a correlation of changes in the expression of these genes to dose level and duration of exposure. Importantly, several of these markers have been shown to reflect a durable, sustained stress response indicative of cancer cell death, particularly in cancer cells from AML patients. Specifically, it was found that the gene HspA1A, a marker of stress response found to correlate with depleted GTP pools in cancer cell lines, is induced within hours upon the first treatment of the drug in patients, even at the trial's lowest doses. Following continued dosing of AVN944, this marker of disease cell stress was elevated even in the absence of circulating levels of the drug between doses. Other genes directly related to IMPDH inhibition showed similar response characteristics.

"AvalonRx, our proprietary gene expression platform, enabled us to identify a set of 34 genes that reflect the mechanism-based activity of AVN944," said David Bol, Ph.D., Senior Vice President of Product and Pharmaceutical Development at Avalon. "These gene markers correlate with the biochemical effects of AVN944 on protein function, which we believe will result in tumor cell apoptosis at the right doses. Our goal for the current Phase I study is to achieve those dose levels in patients. It is very encouraging that we have not seen any drug related adverse events even though we are already seeing biomarker movements consistent with significant inhibition of the IMPDH enzyme. This indicates the potential for a good therapeutic window. Additionally, these data showcase the power of the AvalonRx technology in understanding the pharmacologic, pharmacodynamic and biologic activity of a drug on patients in early clinical studies."

This analysis of the trial data was intended to describe how these biomarkers correlate with biologic activity of the drug in patients as the doses escalate. When comparing patients with different hematologic cancers, examination of the complete set of markers clearly demonstrated the utility of comprehensive gene expression analysis in clinical trials by distinguishing individuals with similar diseases, as well as patients with different malignancies, based on the makeup of their disease prior to drug administration as well as the different nature of the cellular response following drug administration.

About AVN-944

AVN944 is an oral small molecule drug candidate that inhibits inosine monosphospate dehydrogenase (IMPDH), an enzyme that is critical for cells to be able to synthesize guanosine triphosphate (GTP), a molecule required for DNA synthesis and cellular signaling. IMPDH is over expressed in some cancer cells, especially in the case of hematological malignancies. In laboratory experiments, AVN944 has been shown to inhibit IMPDH activity in cells, and suppress pools of GTP. Anticancer activities of IMPDH inhibitors correlate with sustained depletion of GTP pools both in cellular models and in human subjects. AVN944 appears to have a selective effect on cancer cells in that deprivation of GTP in normal cells results in a temporary slowing of cell growth, while GTP deprivation in cancer cells induces cell death, or apoptosis.

Results from preclinical studies of AVN944 indicate that AVN944 inhibited the proliferation of lymphoid and myeloid cells, the principal cells involved in the most common types of human leukemias. In a single-dose, dose-escalation Phase I clinical trial of AVN944 conducted in the United Kingdom in healthy volunteers, AVN944: (1) was well tolerated at all tested doses with no notable side effects; (2) demonstrated good pharmacokinetic properties; and (3) had a significant inhibitory effect on IMPDH enzyme activity. Avalon filed an IND with the FDA in August 2005 and initiated U.S. Phase I clinical trials in January 2006 for the treatment of hematological cancers.
