Sanofi's (SNY) Genzyme Reports Continued Endpoint Improvement for Eliglustat Tartrate in Phase 2 Trials
Up)
Genzyme, a Sanofi company (NYSE: SNY), announced today four-year follow-up data from patients enrolled in the phase 2 clinical trial for its investigational oral therapy for Gaucher disease type 1 known as eliglustat tartrate. Sustained or further improvements were observed across all endpoints, including markers of bone disease, at the four-year timepoint. The results will be presented for the first time this week at the Lysosomal Disease Network WORLD Symposium in San Diego, Calif.
Eliglustat tartrate, a capsule taken orally, is being developed to provide a convenient treatment alternative for adult patients with Gaucher disease type 1, and to offer a broader range of treatment options for patients and physicians to achieve individual therapeutic goals. Genzyme’s Cerezyme® (imiglucerase for injection), the standard of care for patients with Gaucher disease type 1, is administered through intravenous infusions.
Genzyme previously reported that the 52-week phase 2 trial of eliglustat tartrate had met its primary composite endpoint: a clinically meaningful response in at least two of three endpoints (improvements in spleen size, hemoglobin and platelet levels) in individual patients. Patients have continued to receive eliglustat tartrate in the extension portion of the study for over four years. The data from patients on eliglustat tartrate after four years indicate continued or stabilized improvements across all endpoints.
In the phase 2 study, the most common adverse events reported in greater than two patients through four years of treatment included viral infections (six patients), urinary tract and upper respiratory tract infections (four patients each), and nasopharyngitis, sinusitis, arthralgia, pain in extremity, headache, increased blood pressure, abnormal nerve conduction study, abdominal pain, and diarrhea (three patients each). Ten drug-related adverse events, including one serious event, were reported in eight patients. All related events were mild in severity.
Genzyme has also fully enrolled all three phase 3 trials for the oral therapy. Combined, these trials represent the largest clinical program ever focused on Gaucher disease, with participating sites in over 30 countries. In total, more than 350 patients are enrolled in the phase 3 studies.
