LONDON (AFX) - Antisoma PLC announced that R1549, its lead drug formerly known as Pemtumomab, has failed to meet its primary endpoint in a Phase III study in ovarian cancer.

The group, which specialises in the development of novel products for the treatment of cancer, said that the outcome for R1549-treated patients appeared no better than those of patients in the comparative arm of the SMART (Study of Monoclonal Antibody RadioimmunoTherapy) trial.

"Given these findings, it is unlikely that development of R1549 will continue," Antisoma said in a statement today.

The group is co-developing a number of drugs, including R1549, with Swiss pharmaceutical group Roche under the broad strategic alliance formed in November 2002.

"The outcome of this study will have no impact on our growth outlook and we remain committed to our long-term relationship with Antisoma, which is based upon multiple products," William Burns, Head of Roche's Pharmaceuticals Division said.

"Drug development is a high-risk endeavour and such results are not unexpected in the development of novel treatment modalities," he added.

Going downnow at 8p.got any paint left?

Got out yesterday Tabby with a small profit. I see the dog stock is down again today
I may join you for a punt on the dog when it gets to 6p

Why am I not surprised you got out yesterday at a small profit?do you beat yourself at cards as well?as they say at a corrida de toros.thats a lot of bullshit!

Got in on this one this morning at 8.25 oversold IMHO Wont keep for long though

What part of wont keep for long do you not understand. This from a person who against all supports the dog of the year.

As our resident expert on BLNX do you think I should get in on the dog when it gets to SP 6p

So let us get this straightyou got in yesterday at 8p ...claiming the stock was oversoldit ended the day at 8p.so to concluded 8p was good value and 8p wasnt.I get it you could run 26 miles with ease but dont do marathons because the last couple of hundred yards takes it out of you.

Got in at 8.25 got out at 9.75 made enough to pay your council rent for a year.

All we need now is Cynic on board and it will fly

Tabby Invesco Limited upped holding by 5,000,000 plus and three director buys in the last 30 mins.

Nice 8% profit in one day Tabby

Think I may take my profit ahead of USA none farm payroll data due later today. As they say a grand in the hand is worth two in bush.

With the large spreadI dont know where you are going to get anywhere near 8%

Did not buy on spreadbet, purchased 10,000 paid 0.5 tax and 12.50 broker fee
Bought @ 5.58 sold @ 6.00
