The present invention relates to methods of treating ADAMTS-5-associated diseases and particularly osteoarthritis comprising administering an agent capable of modulating ADMATS-5 activity to a subject afflicted with the disease. The agent is preferably a biaryl sulfonamide compound. The invention is based, in part, on the discovery that transgenic animals that do not express functional ADAMTS-5 show a reduction in the degree of osteoarthritis after the induction of osteoarthritis as compared to WT animals. Furthermore, the ADAMTS-5 transgenic animals have reduced aggrecanase activity in articular tissue as compared to WT animals. These animals are good models for ADAMTS-5-associated diseases, and for screening of drugs useful in the treatment and/or prevention of these diseases. There are no other animal models in which the deletion of the activity of a single gene is capable of abrogating the course of osteoarthritis. Accordingly, these animals also show that osteoarthritis can be prevented and/or treated by administering to a subject an ADAMTS-5 inhibitory agent and particularly an agent capable of inhibiting the aggrecanase activity of ADAMTS-5.
本发明涉及治疗ADAMTS-5相关疾病,尤其是骨关节炎的方法,包括向患有该疾病的受试者施用能够调节ADMATS-5活性的药剂。该药剂优选为双芳基磺酰胺化合物。该发明部分基于这样的发现,即不表达功能性ADAMTS-5的转基因动物在诱导骨关节炎后与WT动物相比,显示出骨关节炎程度的降低。此外,ADAMTS-5转基因动物在关节组织中的聚集素酶活性相对于WT动物也有所降低。这些动物是ADAMTS-5相关疾病的良好模型,可用于筛选对治疗和/或预防这些疾病有用的药物。没有其他动物模型能够通过删除单个基因的活性来消除骨关节炎的进程。因此,这些动物还表明,通过向受试者施用ADAMTS-5抑制剂,尤其是能够抑制ADAMTS-5聚集素酶活性的药剂,可以预防和/或治疗骨关节炎。
