The Drug Discovery Dilemma

Finding new medicines is like searching for a needle in a haystack of 400,000 compounds. Traditional drug discovery has been slow, expensive, and unpredictable—but MSKCC is changing that paradigm.

Traditional Timeline

10-15 years from discovery to patient

Repurposing Approach

Significantly reduced development time

Breakthrough: In 2014, MSKCC researchers identified digoxin, a heart medication, as a potential treatment for retinoblastoma through systematic screening 1 .

Drug Repurposing in Action

Assay Development

Researchers designed tests using retinoblastoma cancer cells to identify therapeutic effectiveness 1 .

Primary Screening

The entire chemical library was tested against cancer cells to identify active compounds 1 .

Hit Validation

Initial "hit" compounds were retested to confirm activity and eliminate false positives 1 .

Characterization

Confirmed hits underwent further testing to understand mechanism of action 1 .

Clinical Translation

Digoxin was identified as promising and moved toward clinical application 1 .
