Summary of Clinical Use Click here for help
Vistusertib (AZD2014) is being evaluated in more than 10 Phase 2 clinical trials, for various cancers. Indications include advanced/metastatic breast cancers, glioblastoma multiforme, metastatic clear cell renal carcinoma, (metastatic) squamous non-small cell lung cancer, advanced ovarian cancer and advanced gastric adenocarcinoma. Current investigations favour a combination based approach, for example vistusertib and durvalumab in bladder cancer (Phase 1 NCT02546661) and vistusertib plus rituximab in relapsed/refractory diffuse large B cell lymphoma (Phase 2 NCT02752204). Having shown promise in preclinical animal models of ovarian cancer [8] a combination of vistusertib plus paclitaxel was advanced to human trial in patients with high grade serous ovarian and squamous non-small cell lung cancers. Phase 1 results from this trial (NCT02193633) were published by Basu et al. (2018) [1]. In both cancer types the dual therapy regimen achieved a median progression-free survival of 5.8 months (note: the daily vistusertib dose had to be reduced by half, to 25mg, to manage toxicities in the lung cancer patients).

Mechanism Of Action and Pharmacodynamic Effects Click here for help
Vistusertib's anti-cancer effect is achieved by inhibition of mTOR complexes, and at least in part, by resultant inhibition of downstream ribosomal protein S6 kinase B1 (p70S6K) which is a kinase that is involved in promoting protein synthesis, cell growth, and cell proliferation, and which is associated with human cancers.
