MENLO PARK, Calif., April 01, 2016 (GLOBE NEWSWIRE) -- Versartis, Inc. (NASDAQ:VSAR), an endocrine-focused biopharmaceutical company that is developing somavaratan (VRS-317), a novel, long-acting form of recombinant human growth hormone (rhGH) for growth hormone deficiency (GHD), announced that adherence data from its ongoing Extension Study of somavaratan in children with GHD will be presented today in a late-breaker poster presentation at the Endocrine Society's 98th Annual Meeting & Expo (ENDO 2016), in Boston, MA. Eric Humphriss, MBA, Vice President of Clinical Operations at Versartis, will discuss the results at the Late Breaker poster session (poster LBFri-01) on Friday, April 1, 2016 from 1:15 p.m. – 3:15 p.m. Eastern Time (ET).
Children diagnosed with GHD are treated for an average duration of seven years with daily injections of rhGH, which is currently the only available therapy for GHD in the US and Europe. Treatment adherence is a known burden for GHD patients; non-compliance with daily injections has been reported in up to 66-77% of adults and children with GHD. Studies have also shown that lack of adherence can negatively impact treatment outcome.
Jay Shepard, Chief Executive Officer, commented, “We are greatly encouraged by these results that show better than 99% adherence using a twice-monthly dosing regimen in the at-home setting. The strong adherence data from the ongoing somavaratan Extension Study highlight the potential for improving patient treatment experiences, and potentially outcomes, with a longer acting form of treatment.”
Highlights from Poster Presentation
- With at-home dosing and over 1600 doses administered at the 3.5 mg/kg twice-monthly dose and schedule, dosing adherence was 99.6%.
- Adherence for all dosing schedules over 18 months of at-home therapy resulted in 99.7% adherence.
- This study provides evidence that somavaratan has the potential to improve long-term adherence to growth hormone treatment in children with GHD.
The Extension Study is a long-term safety study that was initiated in March 2014 as patients completed the Phase 1b/2a clinical trial evaluating somavaratan therapy in treatment-naive, pre-pubertal GHD children. At-home dosing was initiated at the beginning of the Extension Study. For assessment of treatment adherence, dosing events were reported by the caregiver using a smartphone-compatible electronic patient-reported outcome diary (eDiary). The eDiary was programmed to provide both assigned injection volume and timing of injection. Caregivers used the eDiary to report injection volume administered and date of administration.
A Phase 3 trial (called VELOCITY) comparing 3.5 mg/kg twice-monthly somavaratan to daily rhGH using the eDiary to monitor treatment adherence is ongoing (NCT02339090).
