Positive Data from Arena Pharmaceuticals' Pivotal BLOOM Trial Demonstrate that Lorcaserin Significantly Improved Markers of Cardiovascular Risk and Glycemic Parameters and was not Associated with Depression or Suicida...(based on a normal Body Mass Index or BMI...),Health

based on a normal Body Mass Index, or BMI, of 25. In addition to the previously announced improvements in glycemic parameters, including fasting glucose, fasting insulin and HOMA-IR, lorcaserin patients also achieved highly significant improvements in HbA1C over one year of treatment (p<0.0001). The greatest improvements were observed in patients with abnormal baseline values.

Quality of Life, as assessed by the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire, also improved to a significantly greater extent in the lorcaserin group than the placebo group at Week 52 (p<0.005). Lorcaserin patients achieved improvements over placebo in all subscores of the IWQOL-Lite, including physical function, self esteem, sexual life, public distress and work.

In addition to the previously announced tolerability data, today's presentation also reported that lorcaserin demonstrated no increase in depression or suicidal ideation compared to placebo. Depression and suicidal ideation were monitored prospectively using the Beck Depression Inventory-II (BDI-II) and by adverse event reporting. At Week 52, 18.0% of lorcaserin patients and 16.1% of placebo patients reported at least a five-point improvement from baseline in BDI-II. A smaller number of lorcaserin patients had increases in the BDI-II total score as compared to placebo. Adverse events related to depression and their total rates at Year 1 for patients who took lorcaserin or placebo, respectively, were 3.1% and 3.0%. In addition, cumulative incidence of suicidal ideation was prospectively evaluated by administration of the BDI-II Questionnaire and did not differ between the lorcaserin and placebo groups at each measurement through two years of treatment.
