The listing of specific trials that involve the drug, as is being done on this page, is misleading and seems to convey an impression that these are the "selected" trials. I would recommend a more general link to all avastin http://clinicaltrials.gov/ct2/results?term=&recr=Open&rslt=&type=&cond=&intr=bevacizumab&outc=&lead=&spons=&id=&state1=&cntry1=&state2=&cntry2=&state3=&cntry3=&locn=&gndr=&rcv_s=&rcv_e=&lup_s=&lup_e= trials in ClinicalTrials.gov.

Contradiction

edit

Does Bevacizumab prolong life or doesn't it? The "clinical use" section says

The panel expressed concern that data from the clinical trial did not show any increase in quality of life or prolonging of life for patients

whereas the "costs" section has

Doctors and editorials have criticized the high cost, for a drug that doesn't cure cancer but only prolongs life

--Commutator (talk) 13:52, 26 September 2008 (UTC)Reply

Bevacizumab has been shown to prolong survival in people with colorectal cancer and certain types of lung cancer. In people with breast cancer, it prolongs progression-free survival, but not overall survival. Fvasconcellos (t·c) 11:18, 29 November 2008 (UTC)Reply

Mechanism

edit

It is now believed that Avastin does not block angiogenesis, but actually increases it. This then stabilises the tumour blood vessels, and allows other chemotherapy agents better access to the tumour site, increasing their efficacy. —Preceding unsigned comment added by 91.110.239.180 (talk) 12:08, 4 May 2008 (UTC)Reply

Bevacizumab Chemical Formula

edit

I am interested in the exact english version (name) la of Bevacizumab. So, if somebody knows it, I would appreciate his-her help! — Preceding unsigned comment added by 195.134.99.82 (talk)

The "zumab" part means humanized monoclonal antibody. The actual antibody may not have another name except for tradenames like Avastin and a sequence.Rbcody (talk) 13:23, 27 April 2008 (UTC)Reply

Clinical Trials

edit

I'd like some information on the clinical trials and success of Bevacizumab, or at least a link to some relevant scientific papers. Also, some information on the development of the drug would be useful. This is a much more interesting reference: http://www.wjgnet.com/1007-9327/13/5857.asp. It's a review on targeting angiogenesis as a treatment for cancer. —Preceding unsigned comment added by Sartchy (talkcontribs) 01:42, 21 November 2007 (UTC)Reply

Which VEGF

edit

Could we clarify if it binds only to VEGF-A (like Ranibizumab) or if it binds to more than one of VEGF ? Rod57 (talk) 02:35, 14 December 2008 (UTC)Reply

It's anti-VEGF-A. "VEGF" is still often used to refer to VEGF-A, so most sources just say bevacizumab is an "anti-VEGF antibody". I'll clarify this in the article and add some references. Fvasconcellos (t·c) 15:41, 14 December 2008 (UTC)Reply
Thanks. I see you updated the drugbox. I've updated the intro to match (after checking ref 1). Rod57 (talk) 15:43, 12 December 2009 (UTC)Reply

Should clarify that bevacizumab blocks BINDING of VEGF-A to a particular VEGF receptor isotype, and identify the isotype. —Preceding unsigned comment added by 70.182.58.2 (talk) 22:21, 26 January 2010 (UTC)Reply

Is there a WikiProject for FDA idiocy? I think this is a prime example, along with things like the PPA fiasco, Meridia, etc. I'd like to see compilations of the number of people killed by the FDA bans or lesser actions or threats, compared to the minor risks of certain medications.

does avastin actually do anything good ?

edit

as i understand the clinical data, for the first indication, avastin improves survival in colon cancer by a median of 5 months; in other cases, initial claims have not been backed up by subsequent trials. This raises a question: does avastin actually do anything at all ? If you take a step back, there are lots of drugs, and lots of clinical trials, so the probablility that one drug will eventually show some effect is high; the statisticians are suppposed to take care of this, but the history of clinical trials - again and again, drugs have smaller effects then thought - shows that for whatever reason, the stat people are not effective. so , it could be that avastin does absolutely nothing, except cause side effects and enrich genentech; —Preceding unsigned comment added by 75.67.134.245 (talk) 19:18, 26 December 2010 (UTC)Reply

One problem is, the FDA sets things up to exclude many good medications. Thomas Eleri pointed out that medications are evaluated for FDA approval in a different process from how they are actually employed clincally. This leads to rejection of efficacious medications and inclusion of less effective ones, simply because inappropriate statistical techniques are employed. The FDA really needs to be wiped clean and reworked.71.203.125.108 (talk) 07:39, 28 December 2010 (UTC)Reply
