The Battle Over Avastin


The use of Avastin for breast cancer was addressed by the U.S. Food and Drug Administration this week. The outcome was devastating for Roche and an emotional one for many women who believe the FDA is subjecting them to a death sentence.  As usual, there are a variety of perspectives to take into consideration.

The history: In 2008, Avastin was given preliminary approval by the FDA for the treatment of breast cancer on the condition that the company would do more studies to demonstrate its effectiveness. Many women have been successfully treated with Avastin -- a billion dollar drug for Roche.

But when Roche submitted the required follow-up studies in 2010, the data showed that there was no benefit from the drug for treating breast cancer.  Studies did not show significant impact on mortality or  improvement in quality of life.  In addition, the drug was associated with some significant side effects such as high blood pressure and blood clots.

In December, 2010, an FDA panel voted to withdraw the drug's approval as a treatment for breast cancer.  Roche appealed the decision, and earlier this week, an FDA panel hearing the appeal unanimously decided, in a 6-0 vote, to withdraw the drug's indication for breast cancer.  The final decision on whether or not Avastin loses the indication is ultimately up to the FDA Commissioner, Dr. Margaret Hamburg.

Hamburg support of the panel's recommendation is critical. At the same time, this will fuel even more emotion and protests among patients. Here's why:

• From the FDA’s side: The FDA issued a provisional approval with the explicit understanding that the final decision would be based on more conclusive studies. If the FDA maintains the drug's approval despite the lack of scientific data, this would likely impact all of their future decisions to offer provisional approvals for potentially life-saving drugs.
• From the patients' side: Women who have benefited from the medication have clearly voiced their opinion that the doctors and patients, not regulators, should decide whether or not to get potentially life-saving treatment.

An important fact to keep in mind is that Avastin will remain on the market because it is FDA-approved for certain types of lung, colon, kidney and brain cancers. Therefore, Avastin will still be available "off label" for treating breast cancer when patients and their doctors believe that this medication is the best option.  In those situations, the only real barrier to access is financial since expensive drugs used "off-label" are frequently not a covered benefit, and very few women can afford  $80,000 per year out of pocket for Avastin.

Roche is understandably passionate about making this drug available to women, and they will be pursuing additional studies to prove its effectiveness.  But, in the mean time, there is a solution that's not been discussed and doesn't involve beating up on insurance companies: For women who decide (despite the data) that they want or need Avastin, Roche could simply decrease the cost.

What do you think?

  1. Archelle: How do you reconcile these two sentences?

    Many women have been successfully treated with Avastin. AND But when Roche submitted the required follow-up studies in 2010, the data showed that there was no benefit from the drug for treating breast cancer.

    Is Avastin an $80,000/year placebo? Or does the follow up studies measure success differently than patient do?

  2. Maybe I'm dating myself, but exchange Rodney King for Casey Anthony - and Bone Marrow Transplants for Avastin (treatment of breast cancer) ... it feels like we're back in 1992. Tremendous emotion voiced then for a treatment that proved ineffective.

    Archelle, first - catchy title. Second your lucid explanation adds significantly to the issue and the media totally missed it. In response to the anonymous poster above, just because on average the whole cohort did not benefit there may be some individuals who did benefit as well as some individuals who had bad side effects. So many medical studies only share the average outcome - this is the basis for personalized medicine where we use genetics/genomics to identify who is likely to benefit from a drug and who is not. Great piece, Dr. Georgiou!

  4. Your final conclusion is logical and makes sense, assuming that Roche really wants to make Avastin more available to women who want it.
    Since they are a for profit firm, however, their primary mission is to make money, not achieve a social goal.
    My prediction: Roche will not significantly reduce the price for women with breast cancer. That would be tantamount to car companies, like Rolls Royce, reducing the price of their cars for people who insist that having such a car will make driving much safer for them.

  5. Avastin will always remain on the market as it is FDA-approved for certain types of lung, colon, kidney and brain cancers.
    Many women have been successfully treated with Avastin .
