Listen Later

Summary

Warning: we recorded ANOTHER 40-minute episode on uveal melanoma! But this time we decided *not* to split it into 2 episodes. So dig in for a long one...there's the use of props at the end!

In this conversation, James and Sapna discuss the FOCUS trial and the use of the melphalan hepatic delivery system. The discussion highlights the importance of understanding the differences between infusion and perfusion, the implications of study design on dropout rates, and the future directions for treatment in this area.


Takeaways

The FOCUS trial showed a high dropout rate due to unappealing control arms.

Melphalan hepatic delivery is a new approach for treating uveal melanoma.

Understanding the difference between infusion and perfusion is crucial for treatment efficacy.

Patient selection is key, especially regarding liver involvement.

The objective response rate of 36.3% is significant for this patient population.

Quality of life post-treatment has improved compared to previous methods.

The study design faced challenges due to high dropout rates.

Future studies may need to consider alternative endpoints for efficacy.

The treatment requires a specialized care team for administration.

Overall survival data is still pending for the new treatment approach.
