Preladenant (SCH-420814) is an adenosine A(2A) receptor antagonist with a high affinity and very high selectivity for adenosine A(2A) receptors, which is being developed by Merck & Co Inc (following its acquisition of Schering-Plough Corp) for the potential treatment of Parkinson's disease. Preclinical studies in rodent and primate models of parkinsonism demonstrated that preladenant can reverse the motor impairments induced by dopamine depletion or antagonism. Phase I and II clinical trials indicated that preladenant was well tolerated. Moreover, preladenant met its major endpoints by reducing OFF time and increasing ON time in l-DOPA-treated patients with Parkinson's disease, without worsening dyskinesias. Therefore, preladenant may have considerable utility for the treatment of Parkinson's disease, as well as the parkinsonian side effects of dopamine D2 receptor antagonists. As research has suggested that adenosine A(2A) receptor antagonists are active in animal models of effort-based decision making, it is possible that preladenant could also be useful for treating energy-related symptoms, such as fatigue, psychomotor retardation and anergia in patients with parkinsonism or depression. At the time of publication, phase III clinical trials were recruiting patients with Parkinson's disease.</p>","PeriodicalId":55031,"journal":{"name":"Idrugs","volume":"13 10","pages":"723-31"},"PeriodicalIF":0.0,"publicationDate":"2010-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29313253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A common mechanism of multidrug resistance used by residual tumor cells involves the expression of the ATP-binding cassette (ABC) transporters.

Iniparib, either alone or in combination with chemotherapy, had significant antitumor activity in preclinical studies in vitro and in vivo. Phase I clinical trials in patients with solid tumors demonstrated that treatment with iniparib was associated with minimal toxicity. Encouraging results were observed in a randomized phase II clinical trial, which demonstrated that the addition of iniparib to gemcitabine and carboplatin led to an improvement in clinical benefit rate, progression-free survival and overall survival in patients with metastatic triple-negative breast cancer (TNBC) compared with gemcitabine and carboplatin alone. A phase III clinical trial to test the survival benefit of iniparib in combination with gemcitabine and carboplatin in metastatic TNBC has completed accrual. Another phase III clinical trial will evaluate the overall survival of patients with newly diagnosed stage IV squamous NSCLC treated with gemcitabine and carboplatin with or without iniparib.
