Outcomes after 8 years of eliglustat therapy for Gaucher disease type 1: Final results from the Phase 2 trial.

Eliglustat is a first-line oral therapy for adults with Gaucher disease type 1 (GD1) and poor, intermediate or extensive CYP2D6-metabolizer phenotypes (>90% of patients). We report the final results of a Phase 2 trial and extension (NCT00358150) in previously untreated adult GD1 patients who had splenomegaly with thrombocytopenia and/or anemia and received 50 or 100 mg eliglustat tartrate (equivalent to 42 or 84 mg eliglustat) twice daily for 8 years. In total, 19 of 26 patients completed the trial. After 8 years of eliglustat, mean spleen and liver volumes decreased by 69% and 34%, respectively. Mean hemoglobin concentration and platelet count increased by 2.2 g/dL and 113%, respectively. All patients met at least 3 of 4 therapeutic goals established for patients on long-term enzyme replacement therapy. Mean final values for patients with severe splenomegaly (n = 6), moderate-to-severe anemia (n = 6), or severe thrombocytopenia (n = 8) were similar to patients with milder disease at baseline and within long-term therapeutic goal thresholds. Biomarker median percent changes from baseline were -91% for chitotriosidase, -87% for CCL18, -92% for glucosylsphingosine, and -80% for plasma glucosylceramide. Mean lumbar spine T-score increased by 0.96, moving from the osteopenic to the normal range. Mean quality-of-life scores, mostly below normal at baseline, moved into ranges seen in healthy adults. Eliglustat was well-tolerated; 98% of adverse events were mild or moderate and 94% were considered unrelated to treatment. Clinically meaningful improvements in all parameters continued or were maintained over 8 years, with the largest margins of improvement seen in the most severely affected patients.

Non-Hodgkin lymphoma comprises a heterogeneous group of haematological malignancies, classified according to their clinic, anatomic-pathological features and, lately, to their molecular biomarkers. Despite the therapeutic advances, nearly half of the patients will die because of this disease. The new diagnostic tools have been the cornerstone to design recent therapy targets, which must be included in the current treatment guidelines of this sort of neoplasms by means of clinical trials and evidence-based medicine. In the face of poor diagnoses devices in most of the Mexican hospitals, we recommend the present diagnose stratification, and treatment guidelines for non-Hodgkin lymphoma, based on evidence. They include the latest and most innovative therapeutic approaches, as well as specific recommendations for hospitals with limited framework and therapy resources.
