Shortages = revenue
Spectrum is benefiting from a shortage of a generic called leucovorin, a less pure version of its Fusilev. In the first quarter, revenue increased 160% year over year.
This would seem to be a temporary one-time benefit, but the shortages are continuing. The Food and Drug Administration still says Teva Pharmaceuticals
In addition to gaining an immediate market share, the longer the shortages go on, the better it is for Spectrum. The more experience doctors have with Fusilev, the more likely they are to stick with the drug after full leucovorin availability resumes.
Once a patient starts on Fusilev, doctors aren't likely to switch patients mid-treatment even if leucovorin is available. In addition to the old adage "if it aint broke, don't fix it," which goes double when you're treating cancer, the drugs are used at different doses -- Fusilev is more purified than leucovorin -- so switching between the two increases the likelihood of a dosing error.
Fusilev is more expensive than leucovorin, but since the drugs treat cancer, patients and doctors are likely to be less concerned with the cost than they would for a chronic condition where the prescription had to be refilled monthly.
Bioscan no more
Spectrum's other drug, Zevalin, has struggled to gain traction despite good efficacy data in part because it was difficult to prescribe. Doctors had to give an initial test dose of the drug and run a bioscan to see where it went before the therapeutic dose could be delivered.
Spectrum recently gained FDA approval to remove the bioscan requirement, which should make it more appealing to prescribe. Spectrum has work to do to get out the message to lymphoma doctors, but there seems to be upside with Zevalin if Spectrum can do it.
I admit this is one of those negatives that's actually a positive. I can't fault someone for looking at this article and deciding Spectrum isn't worth investing in: The specialty pharma business is rather boring.
Spectrum essentially buys drugs that no one else is interested in, trying to reap revenues that justify their bargain-basement prices. The obvious benefit is that it can keep R&D costs relatively low.
Zevalin, for instance, was originally developed by Biogen Idec because the drug is a radioactive molecule linked to the same antibody as Biogen's Rituxan. Cell Therapeutics
Fusilev arrived in a similar manner, purchased from Targent, and wasn't discovered internally.
There's risk investing in these types of drugs, but when a company gets a hit, it can be very lucrative. ViroPharma
Spectrum's management has been doing it long enough that their skills shouldn't be underestimated.
