Very positive and confident statements were made about the results of the study in this interview. I see the following piece of information provided in this interview very assuring:
The people recruited were actually recently diagnosed breast cancer patients. Based on interim results on first five patients they demonstrated:
1. No safety issues with the imaging agents
2. Even though it's too early to say whether imaging agent is being effective, the initial observations are giving good indication that this is moving in the right direction, so will continue the study aiming to get to between 10-15 patients.
3. Based on what they have seen so far they have already started to make plans towards what the next steps for the study might look like.
