The American Society of Hematology's 59th annual meeting continues through Tuesday in Atlanta. Although stocks reacted to the presentation of abstracts in early November, the full presentation elicited incremental reaction, with the direction and magnitude of the moves dependent on the market perception of the data presented.
Here's a list of 10 biotech stocks that moved in reaction to their respective presentations at the ASH:
1. bluebird bio
Bluebird bio Inc BLUE and partner Celgene Corporation CELG announced updated results from the ongoing multicenter Phase 1 study of bb2121 anti-BCMA CART cell therapy in patients with late-stage relapsed or refractory multiple myeloma. The results showed a 94 percent overall response rate in patients in active dose cohorts.
Cantor Fitzgerald's Elemer Piros said the data provided a strengthened profile for the therapy. Piros ascribes a "high" 60-percent probability of success for the program. Bluebird could share peak sales of $2.6 billion by 2026 with partner Celgene, the analyst said.
Bluebird shares closed up 17.91 percent at $201.80 Monday and Celgene was up 1.91 percent to $108.
2. Global Blood Therapeutics
Global Blood Therapeutics Inc GBT said it would present the results of a Phase 2a study of the once-daily oral therapy voxelotor used to treat adolescents with sickle cell disease at the ASH. The results showed increased hemoglobin levels and increased measures of hemolysis at 16 weeks, with a median hemoglobin change of 1.1 g/dL, reduced symptoms at 16 weeks and a favorable tolerability profile in adolescents.
The company is also scheduled to make six additional presentations on the sickle cell disease program.
Global Blood Therapeutics closed down 2.02 percent at $44.78 Monday.
3. Spark Therapeutics
Spark Therapeutics Inc ONCE presented preliminary data on SPK-8011, a treatment candidate for hemophilia A, which showed a 100-percent reduction in annualized bleeding rate, or ABR, and a 98-percent reduction in annualized infusion rate, or AIR, in the first four participants.

The data also pointed to a potential biomarker of response to SY-1365 and synergistic activity with a BCL2 inhibitor in preclinical models of acute myeloid leukemia, or AML.
In a separate release, the company said the Phase II data of SY-1425 showed biological and clinical activity as a single agent in genomically defined AML and myelodysplastic syndrome, or MDS.
