Biogen’s ENDEAR clinical trial results

Hopefully Emma begins her Spinraza treatments on Tuesday, 10/31… Halloween.

The following is from the Biogen pamphlet, “Unlock Her Inner Star”.


SPINRAZA may help improve motor milestone development

Infants taking SPINRAZA showed significant motor milestone improvements early on (day 183) in comparison with untreated infants.

ENDEAR was a well-controlled, 13-month, phase 3 clinical study with 2:1 randomization, meaning two-thirds of the individuals received SPINRAZA and one-third was untreated. The study was ended early as a result of clinically meaningful benefits seen in the planned interim analysis at day 183. All individuals were then moved into open-label extensions for further clinical study.

The interim analysis assessed the proportion of “responders,” or individuals with improvement in motor milestones, according to Section 2 of Hammersmith Infant Neurological Examination (HINE).

Crawling: 8%                                                           Crawling: 0%
Standing: 8%                                                           Standing: 0%
Walking: 0%*                                                          Walking: 0%*

* Individuals in this study were  not of an age at which a healthy infant would typically be expected to walk.

SPINRAZA has been shown to increase the amount of SMN protein produced by SMN2 genes.



Remember that our little Miss Emma sports THREE SMN2 genes!
