Source-derived summary

Ridaforolimus (also known as AP23573 and MK-8669; formerly known as deforolimus) is an investigational targeted and small-molecule inhibitor of the protein mTOR, a protein that acts as a central regulator of protein synthesis, cell proliferation, cell cycle progression and cell survival, integrating signals from proteins, such as PI3K, AKT and PTEN known to be important to malignancy. Blocking mTOR creates a starvation-like effect in cancer cells by interfering with cell growth, division, metabolism, and angiogenesis.

It has had promising results in a clinical trial for advanced soft tissue and bone sarcoma.

Commercial arrangements

Ridaforolimus is being co-developed by Merck and ARIAD Pharmaceuticals. On May 5, 2010, Ariad Pharmaceuticals and Merck & Company announced a clinical development and marketing agreement. With this agreement, Ariad received $125 million in upfront payments from Merck and $53 million in milestone payments. Future payments are triggered upon acceptance of the NDA by the FDA with another payment when the drug receives marketing approval. There are similar milestones for acceptance and approval in both Europe and Japan. Other milestone payments are tied to revenue goals for the drug. ARIAD has opted to co-promote ridaforolimus in the U.S. Merck plans to submit a New Drug Application (NDA) for ridaforolimus to the U.S. Food and Drug Administration (FDA) and a marketing application in the European Union in 2011.

Editorial summary

This brief starts where responsible research should: with the source description of “Ridaforolimus” as chemical compound. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—2010, 2011—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Ridaforolimus, chemical and compound can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as chemical compound. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jan 18, 2026. The linked authority identifier is Q2151796. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2010 and 2011.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
