Onyx Pharmaceuticals (ONXX) Sees New Product Upside

Onyx Pharmaceuticals (ONXX) was one of the few stocks that were up today, closing up $0.63 to $37.86. Still, it is well beneath it's 52-week high of $45.90.

Management thinks the full year will be non-GAAP EPS positive, based largely on a $160 million payment from Bayer this quarter. Bayer sells Onyx's Nexavar for kidney and liver cancer, splitting the after-costs profits. The $160 million was to buy-out the rights for Nexavar in Japan, which has been ramping up to be a lucrative market because of the high incidence of liver cancer there. This was part of a larger deal to end litigation for a Nexavar-related drug, Regorafenib. Under the settlement Onyx will get 20% royalties if the drug makes it to market.

Regorafenib recently had positive Phase III data for metastatic colorectal cancer. Like Nexavar, it appears it may be a useful therapy for a variety of cancers.

The predicted annual positive non-GAAP results were hard to predict before the deal announcement because in most quarters so far Onyx's own operating expenses have been sufficient to wipe out the receipts from Bayer. For Q1 non-GAAP net loss was $14.2 million, for Q2 net loss was $27.2 million, and for Q3 net loss was $19.5 million. One reason for the net losses is that both Bayer and Onyx have been spending large sums on running Nexavar through a set of clinical trials that have shown it may be effective for other forms of cancer, and to strengthen its role in liver caner. If you subtract out the research and development (R&D) costs, in most quarters Onyx would have shown a profit. Onyx has started recruiting patients for Nexavar Phase III trials for breast cancer and thyroid cancer, and has Phase II trials underway in colorectal and ovarian cancer.

Fortunately Onyx Pharmaceuticals has been able to maintain a high cash balance despite the regular losses, ending Q3 2011 at $530 million. Assuming the $160 million payment is a Q4 event, cash at the end of the year should approach $675 million.

I would not expect Regorafenib revenue until at least 2013, and like any drug it could fail for a currently unknown reason.

Carfilzomib is still the key to Onyx's value in the 2012 to 2015 time frame. Carfilzomib is a proteasome inhibitor that had positive data for relapsed and refractory multiple myeloma in a Phase IIb trial. In fact the data was good enough that it is being submitted to the FDA for approval. At the same time two Phase III trials have been initiated. More detailed data from the Phase IIb trial will be presented at the American Society of Hematology (ASH) Annual Meeting, December 10-13, 2011. While there is an outside possibility carfilzomib will not gain FDA approval, the main question is when it will get approval.

If both Regorafenib and carfilzomib are approved by the FDA, the nature of Onyx's model will change. It should be possible, starting in 2013, to have a vigorous R&D program to continue expanding the indications for Nexavar, carfilzomib and other pipeline candidates without actually throwing the bottom line into the red.

I believe that there is always risk in biotechnology stocks from competition, the need for FDA and other national medical agency approvals, and from failure to execute.

However, with expanded indications for Nexavar, plus likely revenues from carfilzomib and royalties on Regorafenib, in the next few years Onyx should become a highly profitable company. I do not think the current stock price reflects full value.

Disclosure: I am long Onyx Pharmaceutical. I have no plans to sell or buy ONXX in the immediate future.
