Puma Biotech Makes Big Breakthrough In Breast Cancer Treatment

Shares of Puma Biotechnology Inc (NASDAQ: PBYI) soared higher by more than 70 percent on Monday after the U.S. Food and Drug Administration posted briefing documents ahead of the regulatory body's review of Puma's PB272 (neratinib) for the extended adjuvant treatment of HER2-positive early stage breast cancer, which is scheduled for Wednesday.

The FDA's Oncologic Drugs Advisory Committee is an independent panel of experts that evaluates data relating to the safety and efficacy of investigational cancer treatments. The committee then makes its recommendations to the FDA although these comments are not binding in the FDA's ultimate decision-making process.

The FDA's report spans more than 150 pages and may be difficult for average investors to decipher. The main conclusion from the report was that the company's study showed statistically significant improvement in patients who were treated with neratinib versus a placebo.

The Street's biotechnology expert Adam Feuerstein‏ tweeted following the release that the report was void of any "landmines" at represents a "win for bulls."
