  • Will Acomplia help with the obesity in America?

    Since its most likely going to be legalized in another yr or two. Also reports very few side effects. Who knows it may become the #1 supplement for no obese people also.

    Acomplia (Rimonabant) - Investigational Agent for the Management of Obesity

    Under development by Sanofi-Aventis, Acomplia (rimonabant) is a selective CB1 endocannabinoid receptor antagonist indicated for the treatment of obesity.

    It works by blocking endogenous cannabinoid binding to neuronal CB1 receptors. Activation of these receptors by endoegenous cannabinoids, such as anadamide, increases appetite. It is the only endocannabinoid receptor antagonist in clinical development and thus offers a unique therapeutic approach to appetite control and weight reduction.

    The drug also has potential as a treatment for smoking cessation because the endocannabinoid system is involved in the body's response to tobacco dependence.

    Sanofi-Aventis filed for regulatory approval with the US FDA and European EMEA in April 2005 and was optimistic that approval would be secured in time for a 2006 launch. However, in February 2006, the FDA declined to issue final approval until a number of issues (unspecified) were resolved.

    Use of Acomplia as a treatment to aid weight loss received a letter of approval from the FDA but its use to aid smoking cessation was considered 'not approvable'. Analysts remain optimistic that Acomplia will eventually be approved for weight loss but that it is unlikely to reach the market before 2007 at the earliest.

    Recently published data confirm the drug’s efficacy in sustaining weight loss but also suggest that subjects treated with Acomplia may have higher rates of psychiatric side effects, such as anxiety and depression, than placebo recipients.
    OBESITY PREDISPOSES TO SERIOUS ILLNESS

    Obesity is now the most common nutritional disorder in western industrialised countries. Defined as a body mass index of greater than 30, it arises from the accumulation of excess fat in the body from overconsumption of fatty foods. Prevalence of obesity in the US and Europe has reached epidemic levels. Data from the World Health Organisation's MONICA project show that in some parts of Europe over 70% of men aged 55-64 years are clinically obese or overweight (BMI >25) and almost 70% of women in this age group. One in five of all Americans is obese and one in three overweight. Furthermore, increasing rates of childhood obesity are likely to exacerbate the trend towards increasing obesity in adulthood.

    There is a strong association between obesity and increased risk of cardiovascular disease and diabetes and possibly certain cancers, such as breast and colorectal cancer. The dramatic rise in the incidence of type 2 diabetes is due largely to the increased prevalence of obesity. Increases in body weight lead to changes in blood lipid and cholesterol levels, predisposing to increased risk of atherosclerosis.
    THERAPEUTIC APPROACHES TO TREATMENT OF OBESITY

    Not surprisingly, the growing prevalence of obesity has stimulated the search for drugs to treat this condition. Various therapeutic strategies have been explored, including:

    * Serotonin and noradrenaline reuptake inhibitors (anorectic agents)
    * Lipase inhibitors
    * ß 3-adrenoreceptor agonists
    * Leptin agonists
    * Melanocortin-3 agonists

    Sanofi-Aventis' approach is completely different to the above. It developed from the knowledge that cannabis smokers often experience extreme hunger pangs, which cannabis smokers refer to as "the munchies". Sanofi-Aventis worked on the premise that if cannabinoids stimulate appetite, blocking cannabinoid receptors in the brain might reduce appetite. The central cannabinoid (CB1) receptors are believed to play a role in controlling food consumption and the phenomena of dependence / habituation. To develop suitable drugs against this target, the human cannabinoid receptor was first cloned and then expressed in cells. Compounds with potential inhibitory activity against this receptor were then screened for inhibitory activity. Rimonabant emerged from this screening process as a potent CB1 receptor antagonist. Preclinical animal studies subsequently showed that it could reduce consumption of fats and sugars, which contribute to weight gain.
    PHASE III DATA HIGHLIGHT EFFICACY AND SAFETY

    The promising preclinical findings with Acomplia (rimonabant) have been confirmed in a series of clinical studies, including pivotal phase III trials involving over 6,000 obese subjects that were carried out in both the US and Europe.

    Two-year data from the phase III multicentre Rimonabant In Obesity (RIO) trials, which compared rimonabant at doses of 5mg and 20mg with placebo with respect to weight reduction and prevention of weight gain, showed that the positive results seen after a year's treatment were sustained over the full two-year trial period. Consistent with the one-year data, the results showed that overweight and obese patients taking rimonabant 20mg/d achieved significant reductions in body weight, waist circumference (an indicator of abdominal obesity) and improved lipid and glycaemic profiles compared with placebo recipients. Rimonabant also had a significant impact on metabolic CVD risk factors, greater than that expected by weight loss alone.

    Efficacy and safety in long-term use is important feature of any antiobesity drug. Some potential antiobesity medications have proved effective in the first six months of treatment only to lose effectiveness as subjects develop resistance to treatment. Data from the RIO trials suggest rimonabant is effective for maintaining weight loss for periods of at least two years. Long-term safety is also a major concern. In the US, the FDA generally requires two years of safety data before approving antiobesity drugs. Results from the phase III RIO trial programme suggest rimonabant is well tolerated in long-term use. Among patients who were randomly assigned to continue their first-year treatment for a second year, 6.7%, 8.3% and 6.0% discontinued from the placebo, rimonabant 5mg and 20mg groups respectively.

    The ongoing phase IIIb trial programme for rimonabant includes studies in patients with diabetes (SERENADE), dyslipidaemia (ADAGIO) and cardiovascular disease (STRADIVARIUS, AUDITOR, CRESCENDO).

    MARKETING COMMENTARY

    The market for weight-reducing drugs has had a somewhat chequered history, characterised by major product withdrawals. Although the statistics suggest a market with enormous opportunity, pharmaceutical companies have so far been unable to capitalise on the need for antiobesity agents. Only two drugs are approved for long-treatment of obesity. They are the lipase inhibitor orlistat, the leading medicine for weight reduction, and sibutramine. Use of both products has been limited by side effects.

    In the prevailing market there is a clear opportunity for an effective and well tolerated antiobesity drug. Potentially, Acomplia may fulfill this role.

    The problem with any drug or surgery aimed to cure obesity is that it relies on the person to follow it's guidelines, dosings, etc. Yeah it'll be great that it will help with the hunger aspect and even help quit smoking, but that doesn't mean people will actually do that. People overeat, binge, etc, for many reasons.. and I believe the least of which is physically associated. I feel obesity is as much a psychological issue as a physical. It is an issue of laziness, willpower, genetics, fear, depression, and something that society has both conditioned and rejected.

      Awesome. I heard about this a while back and knew it was only a matter of time before significant progress was made. Now it’s just up to the government and federal regulators to accept this sort of treatment, I suppose.

        do we need another reason to slack off and hope science can help us get out of the beanbag we have become?

        aust. aint that far behind, if anyone comes over and sees my scorch/basic cuts etc and i make the mistake of telling them its a fat burner, the eyes light up, they ask me where to buy it then proceed to down there scorch and marz bar combo.

        its a joke!

          Sounds like a nice substitute for plastic surgery, being of benefit to the wealthy

              Serious? Even affordable for the socio-economically disadvantaged? What kind of prices are we looking at? Or will they be subsidised..?

                You can get a 15day supply from a website for like 60$ and thats most likely because its not even out yet so they are going to charge more

                  Amen. The only thing that will cure obese people is themselves, we don't need a goddamn pill to fix something they do to theirselves, if they are that weak, I suppose they should suffer the consequences
