ASCO Wrap-Up: A Summary of This Week’s Cancer R&D Headlines

subscribers that the competition leaves Dendreon little margin for error (after it has made quite a few errors in the past two years already). “Dendreon is not dead yet,” Miller wrote. “It could be soon if management doesn’t get it precisely right.”

Better understanding of cancer biology is paving the way for better drugs

Reuters’ Deena Beasley had an encouraging macro story about how the number of cancer drug applications to the FDA is rising, with 20 expected this year. Last year, 10 of the 30 new drugs the FDA approved were for cancer, including a couple that were approved in tandem with diagnostics that select patients with genetic profiles that make them most likely to benefit. “There is greater understanding of some of the disease processes,” said Richard Pazdur, the head of the FDA’s cancer drug office, in an interview with the financial wire service.

The rise of immunotherapy continues

Treatments that find a way unleash the body’s immune system to fight tumors are hot. There are lots of different ways of going about this task, and one of the newer ones is through aiming at a molecular target known as PD-1. This target, as Bloomberg’s Robert Langreth put it, acts like an “off-switch” for the immune system, which tumors cleverly keep in place to allow them to thrive. By hitting the PD-1 target, researchers at Bristol-Myers Squibb hope to unleash the power of the immune system to fight cancer cells as if they were any other foreign invader, like a virus. Merck is also among the pharma companies in pursuit of drugs to fight cancer via the PD-1 route, according to this ASCO preview story by my Xconomy colleague Arlene Weintraub.

Mid-cap biotech companies are driving much of the innovation in cancer drug R&D

While the average citizen might only be able to recognize a few major drug companies by name—Pfizer, Merck, GlaxoSmithKline et. al—much of the innovation on display at ASCO was coming from mid-sized biotech companies. Most cancer drugs have an effect that diminishes with time, but Cambridge, MA-based Ariad Pharmaceuticals (NASDAQ: ARIA) showed that its ponatinib for chronic myeloid leukemia gets more effective as patients are followed up longer. Seattle Genetics (NASDAQ: SGEN) won FDA approval last year for the first truly effective “empowered antibody” for a couple rare lymphomas, and it showed more data at ASCO this year that said the drug can shrink tumors for a majority of patients, even in a tough “re-treatment” setting among relapsed patients. South San Francisco-based Onyx Pharmaceuticals (NASDAQ: ONXX) had “kind of so-so” data to report on its new regorafenib for colorectal cancer, in the words of JP Morgan analyst Cory Kasimov. But the data was much more impressive for carfilzomib (Kyprolis) in newly diagnosed multiple myeloma patients, where it was generating significant tumor shrinkage rates for 89-96 percent of patients, Kasimov wrote.

And that’s really just scratching the surface. Sunnyvale, CA-based Pharmacyclics (NASDAQ: PCYC) showed its drug, designed to hit a target called Btk, was able to achieve meaningful tumor shrinkage for 81 percent of patients with chronic lymphocytic leukemia in a small study, while only 12 percent reported moderate to severe side effects. South San Francisco-based Exelixis (NASDAQ: EXEL) showed a raft of data presentations for its drug that’s designed to work against multiple types of cancer, by blocking a cancer master switch and cutting off blood flow to tumors.

Cambridge, MA-based Aveo Oncology (NASDAQ: AVEO) presented results from a pivotal trial of its kidney cancer drug, and it announced another bold bet at ASCO, saying it plans to compare its treatment head-to-head against a rival from Pfizer in another study in which patients will get to decide which treatment they prefer. Aveo is clearly betting that since its drug has shown a milder side effect profile—prompting fewer dose reductions or interruptions—that patients will choose its drug. RBC’s Kantor called it “A Welcome and Aggressive Marketing Move for AVEO.”

Cancer Diagnostics On the Move

While most of the headlines go to makers of cancer drugs, drugs, drugs—where most of the money is—there are some quite interesting things happening in the world of cancer diagnostics. Cambridge, MA-based Foundation Medicine, a startup backed by Third Rock Ventures and Kleiner Perkins Caufield & Byers, rolled out its product that looks at an array of 200 genes implicated in cancer, which it combines with published scientific literature into a report which is supposed to help doctors select the right drug for an individual patient’s type of cancer. Redwood City, CA-based Genomic Health (NASDAQ: GHDX) had a number of studies to discuss about its Oncotype DX test, which it uses to predict whether certain forms of cancer are likely to recur, and whether patients are likely to respond to a round of chemotherapy.

These diagnostic companies, like drug companies, are under pressure to show that their products are worth their escalating price tags. That makes meetings like ASCO extra-important to them, as they seek to amass bulletproof data sets to show the value of their products. Those debates still feel like they are in the early days, and they will rise in prominence at future ASCOs.
