More information on how the drug compares to diet and exercise, orlistat and sibutramine with regards to cost effectiveness is needed from manufacturers Sanofi Aventis, claimed NICE in a draft technology appraisal issued last week.
NICE also wants an assessment of the drug using the 5 per cent weight loss continuation rule to treatment with rimonabant at three, six, nine and 12 months.
Jeni Wilson, head of communications at Sanofi Aventis said: 'The consultation document represents the preliminary feedback of the appraisal committee and is not formal guidance on this technology.
'The preliminary thoughts of the committee may change after consultation.'
