After reviewing the summary adverse event report data highlighting a shocking number of deaths associated with Omontys, (discussed here), we followed-up with the FDA to request more information. Given the sheer volume of adverse events reported, the FDA could only partially fulfill our request thus far. Below is a brief summary of the case narratives that we have received. We are waiting on additional case studies and intend to follow-up on them once we receive them. The cases below paint a very grim picture for Omontys showing that severe adverse reactions resulting in death occurred despite prompt medical attention, and in two cases (9238609 and 9154117), to patients receiving second doses of Omontys. The FDA data, combined with the lack of commentary about Omontys on Fresenius' (NYSE:FMS) or Takeda's (OTCPK:TKPHF) latest earnings calls and the cash burn at Affymax (OTCPK:AFFY), all lead us to believe that the end is near for Affymax.

Reading between the tea leaves
On 10/31/13, Takeda held its fiscal 2Q'14 earnings call in which there was no mention of Omontys. Omontys is not mentioned anywhere in the earnings presentation and the only sign that it still exists is in a footnote in the data book with the following statement: "An investigation into the root cause of the reactions was initiated and is ongoing." This is exactly the same language Takeda used in a 6/20/13 letter to the EMA and very similar to language that was used in February. With no update, no mention in the primary presentation, and the same vague language about a purported investigation, it sounds like little progress has been made.
On 11/5/13, Fresenius Medical Care hosted its 3Q earnings call in which there was no mention of Omontys returning to market, and in fact, a significant portion of Q&A was devoted to discussing how soon Fresenius would be able to introduce Roche's drug, Mircera, into its U.S. dialysis centers (Mircera is a drug that is already FDA approved, Fresenius has experience administering it in Europe, and it is a drug that has similar dosing benefits to Omontys in that it is dosed once every two weeks without the same negative side effects). When asked about the timing of bringing Mircera to its U.S. centers, Fresenius' CEO said "I really can't give you much comment on that at the moment. It would be inappropriate. But we know how we would do it. So, let me leave it at that." Given the substantially similar dosing benefits, but lack of negative side effects, it is likely that the introduction of Mircera in the U.S. could spell the end for the commercial viability of Omontys in the U.S., and AFFY acknowledges as much, saying "If Mircera enters the U.S. market, we believe it will be in direct competition with Omontys, if Takeda is able to reintroduce the product, because of Mircera's ability to be long-acting; therefore, it could potentially limit the market for Omontys."
Also on 11/5/13, Affymax filed its 10-Q for the period ending 9/30 making no mention of forward progress or a timeline for resolution of the Takeda managed Omontys investigation. Additionally, the financial statements showed SG&A expenses burned through approximately $2mm in the quarter -- despite most restructuring actions and the associated costs having been completed in prior periods - and a cash balance of less than $7mm at the end of the quarter. Given the rate of cash burn, the administrative costs the company would bear in a bankruptcy, the outstanding litigation as well as potential future product liability claims, we believe the end is near for Affymax. Importantly, in the event that the Omontys investigation remains ongoing, we expect Affymax to file for bankruptcy well before it runs out of cash so that Affymax can insure it has enough cash available to navigate bankruptcy. Accordingly, we believe a bankruptcy filing could come as soon as January, at which time cash may be below $5 million.
We remain short AFFY with a price target of $0.44 per share, but the most likely outcome is that the stock is worthless. Our target price is based on a probability weighted basis whereby we assign a 90% probability to Omontys being worthless, and a 10% probability to the upside case of $4.38 per share, implying a $0.44 expected value (assumptions discussed in greater detail here). However, we believe that the data overwhelmingly shows Omontys is unsafe, too many bridges have been burned (FDA, dialysis centers, nephrologists, patients who suffered adverse reactions), and the hurdles for reintroduction are far too high. Therefore the most likely outcome is that Omontys never comes back and the company is worthless.
