    I think all the stuff about the submission being "hard", "complex", "unique" etc is what has worn thin and is a bit of an excuse. BSI has ample experience with high risk devices, including brachytherapies. And they've been dealing with this OSL device for 5 years since first fast-track! The other fact is it is fast approaching the one year anniversary of the rejection. One year! In that time there was no new data for BSI to assess as far as I'm aware - unless OSL ran off and conducted another trial in that time without telling anyone. I doubt BSI are that slow or incompetent.
    The red flag? Something I'd file in the draw marked things I wish I knew about earlier is the MEDDEV 2.7/1 clinical evaluation guidelines (2016, can be accessed online, with thanks to my contacts). Go to:
    Appendix A.6: " Appraisal of clinical data- examples of studies that lack scientific validity for demonstration of adequate clinical performance and/or safety".

    Subsection d: Lack of adequate controls
    " In the following situations bias or confounding are probable in single arm studies and in other studies that do not include appropriate controls"

    - "when effectiveness studies are conducted with subjects that are likely to take effective co-interventions" -
    [for co-intervention- read aggressive " state of art" chemotherapy in panco]

    " ...….it is generally not adequate to draw conclusions based on direct comparisons with external or historic data (such as drawing conclusions by comparing data from clinical investigations with data from published literature"

    It's there in black and white. So why has OSL pushed the approach it has with BSI (single arm safety study, literature comparison) when it's apparent from MEDDEV that such type of approach wouldn't be acceptable from the beginning?
