The news of the FDA breakthrough designation came alongside the release of abstracts from companies presenting data at the upcoming American Society of Clinical Oncology (ASCO) annual meeting in early June.

Previously, GlycoMimetics reported that use of GMI-1271 alongside chemotherapy in AML patients resulted in higher than expected remission rates and lower than expected mortality rates. The ongoing phase 1/2 trial is in its second phase, and in March, management announced its making progress toward completing enrollment in its trial.

On Thursday, management shared additional insight into GMI-1271's efficacy. The company continues to see better than expected results and the overall response rate in 42 evaluable patients was 50%. The mortality rate at the 30-day and 60-day marks was 0% and 7%, respectively, and the median overall survival in the Phase 1 portion of the study was 7.6 months.

Management also reported a 71% remission rate in a cohort of patients age 60 and up who were treatment naive.

Now what

There's an important unmet need for new approaches to battling AML, so it's not too surprising that investors are applauding this data. However, there are no givens when it comes to clinical-stage trials, so investors might want to keep some of their expectations in check until we get the full data read out. GlycoMimetics expects to wrap up enrollment in the relapsing and refractory cohort of the study sometime in the middle of this year.
