Hypothesis

NVP-BEZ235 may have significant efficacy in the treatment of PIK3CA wild-type colorectal cancer.

Conclusion

NVP-BEZ235 treatment results in significant regression of PIK3CA wild-type colonic tumors.

Supporting Evidence

  • In vitro treatment of CRC cell lines with NVP-BEZ235 resulted in decreased cell viability.
  • In vivo treatment of colonic tumor-bearing mice with NVP-BEZ235 resulted in a 43% decrease in tumor size.
  • Longitudinal tumor surveillance showed a significant difference in tumor growth between control and treated groups.

Takeaway

This study shows that a drug called NVP-BEZ235 can help shrink tumors in mice with a type of colon cancer that doesn't have a specific mutation.

Methodology

The study involved in vitro and in vivo experiments using human colorectal cancer cell lines and a genetically engineered mouse model.
