Please Participate in Short Market Research Survey Regarding ERT Infusions.

The National MPS Society has recently partnered with Engage Health, a market research company who is interested in learning more about the perceptions of patients and their caregivers regarding the administration of enzyme replacement therapy (ERT) infusions. The objective of this research is to better understand the logistics involved in getting infusions and patients’ thoughts about those logistics.

If you are a patient or the parent of a patient who receives ERT and are interested in participating in this short survey please click here. The survey will take less than 10 minutes to complete, and no preparation is required. As compensation for your time, a donation will be made to the National MPS Society or other patient association of your choice.

Thank you for your consideration.
