Insights

Deforolimus, an analog of Rapamycin, shows promise as an anticancer drug. This mTOR inhibitor is effective against various cancers, with ongoing Phase III trials for sarcoma treatment.

Area of Science:

  • Oncology
  • Pharmacology
  • Molecular Biology

Background:

  • The mechanistic target of rapamycin (mTOR) is a key target for cancer therapy.
  • Rapamycin (RAP) was the first mTOR inhibitor, but its poor solubility and stability limit its clinical use.
  • Development of RAP analogs is crucial for effective anticancer drug delivery.

Purpose of the Study:

  • To present preclinical and clinical data on deforolimus (AP23573), a novel mTOR inhibitor.
  • To highlight deforolimus's potential as an anticancer agent, particularly for sarcoma.

Main Methods:

  • Review of preclinical studies evaluating antiproliferative activity.
  • Summary of Phase I and II clinical trial outcomes for deforolimus.
  • Discussion of ongoing Phase III clinical trials in sarcoma patients.

Main Results:

  • Deforolimus demonstrated significant antiproliferative activity in preclinical models.
  • Phase I and II trials showed encouraging results in various tumor types, including sarcoma.
  • A Phase III trial for sarcoma is currently underway, indicating promising therapeutic potential.

Conclusions:

  • Deforolimus is a promising mTOR inhibitor with demonstrated efficacy in preclinical and early clinical studies.
  • Its favorable profile supports its continued investigation as a novel anticancer therapeutic.
  • Deforolimus holds potential for treating challenging malignancies like sarcoma.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
