. On 18 May 2017, the European Medicines Agency recommended the refusal of the marketing authorisation for the medicinal product, intended for the treatment of anorexia, cachexia or unintended weight loss in patients with non-small cell lung cancer. Helsinn requested a re-examination of the initial opinion. After considering the grounds for this request, the European Medicines Agency re-examined the opinion, and confirmed the refusal of the marketing authorisation on 14 September 2017. The European Medicines Agency concluded that the studies show a marginal effect of anamorelin on lean body mass and no proven effect on hand grip strength or patients’ quality of life. In addition, following an inspection at clinical study sites, the agency considered that the safety data on the medicine had not been recorded adequately. Therefore, the agency was of the opinion that the benefits of anamorelin did not outweigh its risks.
