Abstract

INTRODUCTION: The mTOR (mechanistic target of rapamycin, formerly known as mammalian target of rapamycin) kinase is centrally involved in the regulation of cell growth and metabolism in response to intra- and extracellular energetic stimuli and growth factors. The importance of mTOR in health and diseases has fueled the development of molecules that inhibit mTOR signaling, including rapalogs (sirolimus, temsirolimus, everolimus and deforolimus), which complex with FK506-binding protein 12 (FK-BP12) to inhibit mTOR complex 1 (MTORC1) activity in an allosteric manner, or the more recent ATP-competitive mTOR inhibitors (mTORi), which target the catalytic site of the enzyme. However, clinical development of these mTORi has revealed that these drugs produced numerous side effects that could be serious and/or debilitating. Despite pharmacological efforts to develop drugs with an improved safety profile, these side effects are often unpredictable and may frequently preclude the efficiency of mTORi. AREAS COVERED: The objective of this review is to perform a comprehensive survey of the safety profiles of various rapalog-based therapies from the available clinical literature. The authors will discuss the potential mechanisms of these therapies, taking into account the knowledge of the biological pathways regulated by mTOR. EXPERT OPINION: A better prevention and management of mTORi-related side effects requires the identification of alterations in related biological pathways that will help to delineate therapeutic targets.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
