Hypothesis
Can buccal punch biopsies serve as effective pharmacodynamic biomarkers in drug development?
Conclusion
Buccal punch biopsies can effectively quantify key biomarkers for assessing drug effects in cancer treatment.
Supporting Evidence
- 100% of volunteers stated they would undergo the biopsy procedure again.
- Markers such as total pRb and phospho-pRb showed good signal detection.
- Biopsy procedures were well tolerated with minimal adverse events.
Takeaway
Doctors took small samples from the inside of people's cheeks to see how cancer drugs work, and everyone said it was okay to do again.
Methodology
Two open nonrandomised studies were conducted with healthy male volunteers to assess tolerability and biomarker detection in buccal biopsies.
Potential Biases
Potential bias due to the nonrandomized design and the specific demographic of healthy male volunteers.
Limitations
The study was limited to healthy male volunteers, which may not represent responses in females or cancer patients.
Participant Demographics
Healthy male volunteers aged approximately 45 years.
