Using canSAR Database to Learn About Cancer Drugs and Targets

Imagine that you heard about a groundbreaking hot new cancer drug on the evening news. And you are curious, and you want to find more about this drug. Where would you turn to? Google? 

Among the search engine hits will be a press release from the company and a multitude of news commentaries and blogposts, all various incarnations of the press release itself. These sources will have a summary of the best results from the Phase 3 clinical trial, promising (maybe self-congratulatory) statements from the CEO or CMO of the company, a paragraph on safety signals and usual disclaimers.

But what if you actually want to know more about the drug target, its biology, chemistry, structural biology, pharmacology, bioactivity (and experimental models) and all kinds of apparently boring (to the investment community) scientific data. 

This "mundane" data is generally scattered in journal articles, conferences abstracts and posters, and patent filings. Now there is an easier way to get a snapshot of this data: via a public database canSAR.

Cost of Cancer Drug Development, 4 Billion. Cost to Patient, 0.1 Million. Benefit, Priceless! Business Model, Unsustainable

I recently rediscovered an article by Forbes's Mathew Herper, "The Truly Staggering Cost Of Inventing New Drugs." In this article, Mathew pegs the true cost of bringing drugs to market at 4 billion dollars.

OncoBrands We Used to Know in 2011

Oncology is one island where biotech investment continues in the sea of shrinking biopharma.  As expected, the current environment is also conducive to oncology biotech companies being lost to mergers and acquisitions.  Sadly, these carefully crafted and nurtured brands will be lost for ever!

Deploying Immunotherapeutic Drones for Cancer

Nearly six scores ago, a Westfield, Connecticut, based bone surgeon, William Coley, injected a mixture of dead Streptococcus pyrogens and dead Serratia marcescens bacteria (called Coley's vaccine or Coley's toxins) in patients' tumors and obtained a near-complete remission.  Nearly a quarter century after his death, the powerful immune stimulant in Coley's vaccine was identified as tumor necrosis factor-alpha (TNF-α) in 1968.  Today, there is a renewed interest in Coley's approach and the immunotherapeutic strategies to control cancer.

28% of Phase III Failures are in Oncology Trials

John Arrowsmith of Thomson Reuters, who described these numbers in a Nature Reviews Drug Discovery article, listed three major reasons for Phase III failures in oncology:

The Prostate Cancer: New drugs in the post “Abiraterone-Jevtana-Provenge” world

The success of three new drugs (Abiraterone, Jevtana and Provenge) for castration-resistant prostate cancer (CRPC) this year, each targeting different pathways, and all showing an overall survival benefit, has raised the bar for those dreaming to join the club.  There is at least one riding the popularity vote, MDV3100, which may complete phase 3 next year.  Still, many struggle and plough through phase  1 and 2.  One way to understand, what may make some of them unique – and the reason they may evolve into serious competition one day – is to lay them out in separate classes or targets.  This is what I have done below.

Cancer drugs RIPed in 2010

Four of the top ten Phase III failures of 2010 that were listed at FierceBiotech on Oct 21st are cancer drugs, and that's a big number!
