Why Geron Shares Doubled
Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.
What: Shares of biotechnology company Geron gained as much as 116% this morning after its experimental bone marrow disorder drug helped patients in a study.
So what: In the 18-patient Mayo Clinic study of Geron's imetelstat, 44% experienced clinical improvement, partial remission, or complete remission, triggering plenty of optimism over the drug's blockbuster potential. To be sure, The Street's biotech expert Adam Feuerstein noted that only bone marrow and blood responses were reported -- no clinical or symptomatic responses -- suggesting that Mr. Market might be overreacting to the data.
Now what: Geron will post updated results next month at the American Society of Hematology meeting in New Orleans.
"The current study signifies the potential value of telomerase-based treatment strategies in MF and identifies imetelstat as an active drug in that regard," the study's abstract reads. "The association between response and spliceosome mutations suggests a broader application for the drug in myeloid malignancies."
For lucky Geron shareholders waking up to today's whopping gain, however, taking some dough off the table seems prudent given the seemingly reasonable skepticism surrounding the initial abstract.
