Summary:The present invention relates to a lyophilization process for preparing a teverelix-TFA lyophilizate, said process comprises the following steps: a) providing a lyophilization suspension by mixing teverelix and trifluoroacetate at a molar ratio sufficient for providing an microcrystalline teverelix-TFA suspension without formation of a gel, and b) lyophilizating the lyophilization suspension, thereby providing a teverelix-TFA lyophilizate. The process provides the possibility of obtaining a "pure" teverelix-TFA lyophilizate i.e. without any undesirable residues in the composition. La présente invention concerne un procédé de lyophilisation permettant de préparer un lyophilisat de teverelix-TFA, ledit procédé comprenant les étapes suivantes : a) obtenir une suspension de lyophilisation en mélangeant du teverelix et du trifluoroacétate dans un rapport molaire suffisant pour obtenir une suspension microcristalline de teverelix-TFA sans formation d'un gel, et b) lyophiliser la suspension de lyophilisation, produisant ainsi un lyophilisat de teverelix-TFA. Le procédé permet d'obtenir un lyophilisat de teverelix-TFA "pur", c'est-à-dire sans résidus indésirables présents dans la composition.
