Highlight of Business Operations:

Obesity is a chronic disease condition that affects millions of people and often requires long-term or invasive treatment to promote and sustain weight loss. In the National Health and Nutrition Examination Survey, or NHANES, conducted for 2007-2008, 68% of adults in the United States (72.3% of men and 64.1% of women) were classified as overweight, defined as a body mass index, or BMI >25, and 33.8% were obese (BMI >30). Data from NHANES also found that almost 17% of school children were obese and almost 32% were overweight for the 2007-2008 time period. Obesity in children is defined as having a BMI at or above the 95th percentile and being overweight is defined as having a BMI at or above 85th percentile. The percentage of American men and women classified as overweight and obese has more than doubled since 1962. Researchers fear that the percentage of American adults that are obese could climb as high as 43% in the next ten years.

The EQUATE study met the co-primary endpoints by demonstrating weight loss with both the full-dose and mid-dose of Qnexa were significantly greater than the individual drug components and placebo. Patients treated with full-dose and mid-dose Qnexa had an average weight loss of 9.2% and 8.5% respectively, as compared to weight loss of 1.7% reported in the placebo group (ITT-LOCF p<.00001). Average weight loss was 19.8 pounds and 18.2 pounds in the treatment arms as compared to 3.3 pounds in the placebo group. Qnexa was well-tolerated, with no reported drug-related serious adverse events in the study. The proportion of patients losing 5% or more of their initial body weight was 66% for full-dose, 62% for mid-dose and 15% for placebo (ITT-LOCF p<0.0001).

The EQUIP study met the co-primary endpoints by demonstrating that patients treated with full-dose and low-dose Qnexa had an average weight loss of 11.0% and 5.1% respectively, as compared to weight loss of 1.6% in the placebo group (ITT-LOCF p<0.0001). Average weight loss was 37 pounds and 18 pounds with full-dose Qnexa and low-dose Qnexa, respectively, as compared to 6 pounds in the placebo group. The proportion of patients losing 5% or more of their initial body weight was 67% for full-dose, 45% for low-dose and 17% for placebo (ITT-LOCF p<0.0001).

The CONQUER study also met the co-primary endpoints by demonstrating that patients treated with full-dose and mid-dose Qnexa had an average weight loss of 10.4% and 8.4%, respectively, as compared to weight loss of 1.8% in the placebo group (ITT-LOCF p<0.0001). Average weight loss was 30 pounds and 24 pounds with full-dose Qnexa and mid-dose Qnexa, respectively, as compared to 6 pounds in the placebo group. The proportion of patients losing 5% or more of their initial body weight was 70% for full-dose, 62% for mid-dose and 21% for placebo (ITT-LOCF p<0.0001).

Fasting plasma glucose levels were reduced in patients treated with Qnexa from 176 mg/dL to 133 mg/dL, as compared to a decrease from 171 mg/dL to 145 mg/dL for the placebo group (p=0.02). Over 56 weeks, patients treated with Qnexa also lost 9.4% of their baseline body weight, or 20.5 pounds, as compared to 2.7%, or 6.1 pounds, for the placebo group (p<0.0001). Sixty-five percent of the Qnexa patients lost at least 5% of their body weight as compared to 24% in the placebo group (p<0.001), and 37% of the Qnexa patients lost at least 10% of their body weight as compared to 9% of patients in the placebo group (p<0.001). Patients treated with Qnexa had reductions in blood pressure, triglycerides and waist circumference. Both treatment groups had a study completion rate greater than 90%.

Despite a mean baseline HbA1c level of 8.8%, 53% of the patients treated with Qnexa were able to achieve the ADA recommended goal of 7% or lower, versus 40% of the patients in the placebo arm (p<0.05). The incidence of hypoglycemia in the treatment and placebo arms were similar (12% and 9%, respectively). Patients in the Qnexa arm experienced no treatment-related serious adverse events.
