mTOR Inhibitors currently exhibits a proliferating pipeline with approximately 30 drug candidates, According the study published by P&S Intelligence
The mechanistic/mammalian target of rapamycin (mTOR) is a serine threonine protein kinase, that belongs to the phosphatidylinositol-3-kinase-related kinase family. Molecules in this family have more than 2,500 amino acids, and they harbor a kinase domain at their C-terminals. It has been observed that the increasing prevalence of cancer along with its high healthcare cost, globally, has been driving the growth of mTOR inhibitors pipeline. For instance, the number of people living beyond cancer diagnosis reached around 14.5 million in 2014 and is expected to increase to 19 million, by 2024. In 2010, approximately $125 million was spent on cancer care in the U.S., and it is expected to reach $156 million, by 2020.
Other factors strengthening the mTOR inhibitors pipeline include smoking, obesity unhygienic food, and allergy. The study analyzed that mTOR inhibitors therapeutics pipeline comprises approximately 30 drug candidates in different stages of development.
Insights on pipeline segments
According to the research findings, most of the drug candidates that act as mTOR inhibitors are being developed as small molecules, further supported by the fact that small molecules have several advantages such as it can be manufactured with production rate higher than any other molecule types.
Positive Clinical Results of mTOR Inhibitors Therapeutics Candidates
The positive clinical results of mTOR inhibitors drug candidates is a key factor driving the pipeline growth. For instance, F. Hoffman-La-Roche AG has developed a drug candidate, ipatasertib, that acts as mTOR inhibitors. The Phase II clinical results (Study ID: NCT02162719) of the drug candidate were published in the Lancet Oncology journal. It has been observed that progression-free survival was longer in patients who received ipatasertib as compared in those who received placebo.
Technological Advancements for mTOR Inhibitors Therapeutics Drug Development
Most of the companies are developing innovative technologies for the synthesis or production of mTOR inhibitors. For instance, PHusis Therapeutics Inc. is using its computational modeling platform namely, PHuDock, that identify inhibitors of proteins which promotes the growth of cancer cells. Using PHuDock, X-ray structural information and surface plasmon resonance spectroscopic measurements of selected drug-like molecules, PHusis is rapidly and efficiently identifying agents involving toxicity studies, that selectively inhibit the activity of a number of these cancers driving proteins. PHuDock is applied to lead identification and optimization, as well as to predict the compounds off-target properties and toxicity, therefore delivering novel and highly effective agents with low toxicity.
These technologically advanced platforms enable the players in the pipeline to develop effective new therapies rapidly, that are cost effective and potentially have lower risk of toxicity, and relative to traditional approaches. Thus, these technological advancements act as a key driver for the pipeline growth.
Some of the key players involved in the development of mTOR inhibitors therapeutics include F. Hoffman-La-Roche AG, Pfizer Inc., and resTORbio Inc.
