ChangeWave Research Report:

Trends in Diabetes Treatments and Obesity

Overview

During the week of January 17-23, 2007, we surveyed Alliance healthcare members on trends in diabetes treatments and obesity, including the drugs Exubera, Byetta (Exenatide) and Januvia. A total of 137 doctors participated.

(A) Inhaled Insulin (Exubera)

Bottom Line. The outlook for Inhaled Insulin remains positive. Doctor respondents believe two-thirds of their existing diabetes patients would prefer inhalable insulin rather than the injectable form. They also estimate four-in-five newly diagnosed patients would prefer inhalable insulin.

The findings onExubera –the only form of inhalable insulin currently available –were positive, with 48% of doctors saying they’re Very or Somewhat Likely to recommend it to their diabetes patients over the next year. We note that 19% say they’re Veryor Somewhat Unlikely to recommend it.

(B) Byetta (Exenatide) and Januvia

Bottom Line: In a consensus estimate, doctors say 9% of their type 2 diabetes patients currently use Byetta, but they believe 15% will begin using it over the next 12 months. Turning to recently approved Januvia, the consensus is that 8% of type 2 diabetes patients have already inquired about Januvia, and 14% will begin using it over the next 12 months.

We note that doctors rank Glucophage (12%), Glyberide (11%) and Glucotrol (10%) as the treatments most likely to be displaced by Januvia within their practice.

(C) Obesity

Bottom Line: The findings point to a risingnumber of obese patients, with three-quarters (75%) of doctors reporting an increase within their practice over the past year. Moreover, 64% say there has been an increase in the number of dangerously or morbidly obese patients over the past year.

  • Top Weight Control Drugs Recommended. Xenical (28%) and Meridia (22%) are the top weight controldrugs doctor respondents recommend to their obese patients, followed by Adipex (15%) and Ionamin (15%).
  • Most Effective Drugs. Doctors consider Xenical (11%) to be the most effective weight control drug they recommend, followed by Adipex (9%) and Meridia (8%).
  • Weight Control Products. Weight Watchers (44%) is the top weight control product/ diet that doctors have recommended to obese patients over the past 12 months. A Low-Carb Diet (35%) ranks second, followed by a Low Fat Diet (32%). Similarly, these remain the top products/diets doctors say they’ll recommend over the next 12 months.

(6B) Question Asked: Why?

A Sample of Alliance Member Responses:

(a) Xenical (11%)

  • Doctor DR.32051 writes, “Clinical trial results.”
  • Doctor JOH89542 writes, “I find it a very good product which gives significant results.”
  • Doctor MED63234writes, “Compliance and degree of weight loss.”
  • Doctor BOY70648 writes, “Easy compliance.”
  • Doctor NAL80131 writes, “Forces patients into a low fat diet.”
  • Doctor STE3218writes, “Stops absorption of fat, but time to meal sensitive and causes diarrhea. None of the treatments overly effective.”
  • Doctor NIN8017 writes, “Actually none really, all put weight on again after stopping, minimal weight loss on rx and horrid GI side effects with Orlistat, there is no real substitution for eating less and exercising more.”

(b) Adipex (9%)

  • Doctor LEO7024 writes, “Suppresses appetite more smoothly and effectively.”
  • Doctor AFA3665 writes, “Suppresses appetite leading to significant weight loss along with fewer side effects.”
  • Doctor RBH82876 writes, “Part of the previously wildly successful Phen-Fen regimen of years past.”
  • Doctor DOC03757 writes, “Most effective weight loss; few side effects. Limited by length of treatment.”
  • Doctor REP44662 writes, “Patients seem to be the most compliant with this med.”
  • Doctor DR.4072 writes, “Adipex for individuals without cardiac issues or with GI issues and Xenical for individuals without GI issues and with cardiac issues – decreases appetite over the long term although Fastin does develop a tolerance and Xenical in addition to the fat soluble binding does teach patients how much fat they can safely eat over their body weight – based on personal prescribing experience and research studies.”

(c) Meridia (8%)

  • Doctor YOR67603 writes, “Seems to control appetite better.”
  • Doctor OCE43646 writes, “Decreased appetite continues if Meridia continued long term, but better drugs in pipeline, and GI bypass remains gold standard for morbidly obese.”
  • Doctor PAU3772 writes, “We have seen significant weight losses.”
  • Doctor SMC61289writes, “Meridia's better tolerated, however all of the treatments are much less effective than bariatric surgery.”
  • Doctor BUC85235 writes, “Good compliance.”

(d) Ionamin (5%)

  • Doctor FRU28890 writes, “Cheap, well-tolerated, and safe.”
  • Doctor MIK3319 writes, “It inhibits appetite and increases metabolism, or so it seems.”
  • Doctor MJB75931writes, “Despite stimulant risk people lose weight they just can’t keep it off.”
  • Doctor MES04968 writes, “Patients report appetite suppression and exhibit weight loss over the short term.”
