    Meeting Minutes

    2022-10-19: Minutes of Biomarkers SIG October 2022 meeting

    We had a very productive October meeting, and 18 SIG members joined the call.

    Deepak Parashar gave a great presentation about “Predictive biomarker enrichment designs in Phase II clinical trials”. This started with a nice introduction on the topic and was followed by the latest on state-of-the-art research on that topic.

    The next few months are going to be busy for the PSI Biomarkers SIG as Nicole Krämer and Guillaume Desachy will be attending the PSI Strategy Day 2022 in November and the whole group is getting ready for our January 2023 Webinar as well as for a PSI Biomarkers SIG session at PSI in June 2023!

    The PSI Biomarkers SIG meets monthly, on the third Wednesday of each month from 9AM CET to 10AM CET. The next meeting is scheduled for November 16th.


    Please contact us if you would like to join the SIG!


    2022-09-21: Minutes of Biomarkers SIG September 2022 meeting

    We had a very productive September meeting, and 16 SIG members joined the call.

    How to use interpretable AI to generate biomarker features from multi-modal data? This was the topic of a presentation by one of the participants, followed by a lively discussion.

    Our first PSI/EFSPI Webinar on Biomarkers will take place in Q1 2023!
    You can look forward to three presentations on our current priority topics:

    • Biomarker-based Designs
    • Machine Learning for Biomarker Analysis
    • Identification of publicly-available datasets to create a data repository

      The PSI Biomarkers SIG meets monthly, on the third Wednesday of each month from 9AM CET to 10AM CET. The next meeting is scheduled for October 19th.


      Please contact us if you would like to join the SIG!


      2022-07-20: Minutes of Biomarkers SIG July 2022 meeting

       

      We had a lively July meeting, with 12 participants joining the discussion despite the summer break.

      After introducing several new members to the group, we planned

      • a joint meeting with the Subgroup SIG on subgroup identification and predictive methods for biomarker data.
      • a collaboration with the Visualization SIG and their Wonderful Wednesdays session. To identify an exciting visualization challenge, our sub stream “Data repository of publicly available biomarker data” will be very helpful.

      We plan to have presentations from SIG members on the two other sub streams “Machine Learning for Biomarker Analysis” and “Biomarker-based Designs” in the upcoming meetings.

      The PSI Biomarkers SIG will meet on a monthly basis the third Wednesday of each month from 9AM CET to 10AM CET. The next meeting is scheduled for August 17th.


      Please contact us if you would like to join the SIG!




      2022-06-22: Minutes of Biomarkers SIG June 2022 meeting

      We had our third meeting of the Biomarkers SIG, with 15 participants discussing biomarker-related topics.

      One of the members of the Biomarkers SIG shared an overview of subgroup identifications methods and how these can be used in the context of biomarkers, be they prognostic or predictive.

      The Biomarkers SIG also debriefed on the PSI Conference 2022 and is grateful for the support coming from PSI, EFSPI and the whole community.

      The Biomarkers SIG is now organizing itself in sub-working groups, focusing on the following topics:

      1. Machine Learning for Biomarker Analysis
      2. Biomarkers-based designs
      3. Building a data repository of publicly-available biomarker data

      The PSI Biomarkers SIG will meet on a monthly basis the third Wednesday of each month from 9AM CET to 10AM CET. The next meeting is scheduled for July 20th.


      Please contact us if you would like to join the SIG!


      2022-05-19: Minutes of Biomarkers SIG May 2022 meeting

      We had our second meeting of the Biomarkers SIG, with 14 participants discussing biomarker-related topics.

      Based on our brainstorming session during the kick-off, we identified three areas that we want to focus on during the next months:

      (1)    Machine Learning for Biomarker Analysis

      (2)    Biomarker-based designs

      (3)    Identification of publicly-available datasets to create a data repository

      Our goal for this year is to organize a webinar later this year.

      Further, we plan to work on a data repository with biomarker data. This can be used for benchmarking and evaluation of statistical methods.

      The PSI Biomarkers SIG will meet on a monthly basis the third Wednesday of each month from 9AM CET to 10AM CET. Due to PSI, the next is however postponed to June 22nd.

      Please contact us if you would like to join the SIG!



      2022-04-20: Minutes of kick-off meeting

      We kicked off the PSI Biomarkers SIG on April 20th with 12 enthusiastic participants, coming from both academia and the private sector.

      After brief introductions, we collectively brainstormed on subjects of interest for this SIG, using a virtual board.  

      To give all SIG members the possibility to contribute, the virtual board will remain open until May 4th and we will then send a poll to PSI Biomarkers SIG members to choose specific topics to be explored in the months to come.

      The group discussed short-term and mid-term goals. These include a poster presentation at PSI 2022 in June 2022 and the possibility to organize a PSI webinar with 2 to 3 biomarkers-related topics in Q3/Q4 2022.

      The PSI Biomarkers SIG will meet on a monthly basis the third Wednesday of each month from 9AM CET to 10AM CET. The next meeting is scheduled for May 18th.

      Upcoming Events

      To be announced

      The PSI / EFSPI Biomarkers Special Interest Group has been formed with the aim of developing knowledge and opinions within the statisticians about biomarker usage and the related statistical and study design techniques that are involved. We hope to provide a forum for discussion and the sharing of experiences regarding the use of biomarker data across all stages of pharmaceutical development, in topics such as:

      • Developments in Biomarker Statistical Metholodology related to the pharmaceutical development
      • Statistical issues involving the Translation of biomarkers from pre-clinical in-vivo and in-vitro models
      • The development of the statistical expertise on the  use of Omics (genomics, proteomics, metabonomics  and other multiplexed molecular assay systems) as a means for identifying potential biomarkers
      • Statistical issues relating to Biomarkers of safety and toxicity
      • Statistical Validation  and qualification of biomarkers
      • Biomarkers in clinical development, biomarker clinical study designs, stratification of patient populations, prediction of clinical response, diagnostics and related statistical issues in personalised healthcare 
      • The statistical assessment of benefits and costs of using biomarkers

      If you have experience in one of these other areas, or in biomarker usage in general and would like to participate in the SIG, its committee or a future meeting then please contact Athula Herath ( heratha@medimmune.com). Similarly if you would just like to be kept informed of our activities then please get in touch. More info can be found on our pages in the resources section of psiweb.

      Mailing list and LinkedIn Group

      To keep up to date with the activities of the SIG, contact us to join the mailing list. This will keep you up to date with our events and other interesting pieces of news. Similarly, we have a LinkedIn group where you can start and participate in discussions on biomarker related statistical topics.

      Paper - A Statistician's Perspective on Biomarkers in Drug Development

      The SIG's thoughts and advice have been summarised in a review paper in the 10th anniversary edition of Pharmaceutical Statistics (November/December 2011, Volume 10, issue 6). This paper entitled "A Statistician's Perspective on Biomarkers in Drug Development" provides practical advice to statisticians working in the field. It can be found on the journal website here

      In addition an overview of the publication was also presented at the PSI Journal Club in September 2012. Slides and a recording of the presentation can be found from the PSI Journal Club webpage here.

      A list of biomarker related references from the scientific literature can be found here. This includes many references from the review article, but with further additions too. Weblinks are included in the document.

      Omics Web Resources

      A list of web based resources for those new to 'omics work, including genomics, mass-spec etc is being established. This list can be found here in our resource folders.
