Event Agenda

Below is the 2016 Agenda outlining speakers and topics discussed at the 10th Annual Extractables & Leachables conference in Dublin.

Tuesday 8 November

Tuesday 8 November

  1. Workshop: Leachable Risk Assessment: A structured approach to meet regulatory expectations

    Led by representatives from Smithers Rapra, Baxter Healthcare and GlaxoSmithKline

    The workshop will focus on leachable risk assessment and therefore a pre-read package on the basics of extractable and leachable with send to delegates in advance of this course, enabling the workshop to devote more time on the technical risk assessment process. The workshop is designed to give practical experience of performing a technical risk assessment to evaluate exposure risk to patients from leachables derived from container closure or manufacturing materials and then use extractable and/or leachable testing as risk reduction activities to meet regulatory expectations.

    It will consist of a mixture of short  presentations and predominately an interactive element performing a risk assessment on a fictitious medical product.  The facilitators from Smithers Rapra, Baxter Healthcare and GSK will assist in the workshop and give the presentations.

    The presentations will cover the concepts and themes associated with a science led risk based approach to extractable and leachable testing and its close alignment to concepts of quality by design and lifecycle management aligned to guidance of Drug Product Development (ICHQ8) and Quality Risk Management (ICHQ9).

    Interactive element will cover:

    • Risk identification (cause and effect)
    • Risk evaluation & analysis (knowledge gathering and scoring)
    • Risk reduction (Extractable and/or leachable testing)

    The workshop will cover the entire day and will include a light lunch. Please ensure you include your role in extractables and leachables when booking your ticket so teams can be assigned with a diverse mixture of people.

    *Please note, if you register to attend the workshop you will be unable to attend the site visit to NIBRT.

    Finishes at 5.30pm.

  2. Site Visit: NIBRT

    To celebrate the 10th anniversary of Extractables & Leachables Europe, we'll be visiting NIBRT's Dublin facility. This is the first time ever that a site visit has taken place as part of the E&L Europe conference!

    Taking place before the 2-day conference on Tuesday 8th November 2016 from 14:00 - 17:00, this is the perfect way to kick off your Extractables & Leachables conference experience.

    As part of the site visit, participants will take part in an interactive tour of the bioprocessing pilot plant, with access to all production areas.  This will give visitors a good understanding of the process flow and the equipment involved in the bioprocessing industry. 

    The site visit will include a light lunch.

    • Chemical modifications to single amino acids of a biological in extreme cases may cause adverse effects such as immunological response, but at least diminish product quality
    • We propose a screening approach using model substrates similar to the OCED TG442C guideline for testing in-chemico skin sensitation
    • First results of an LC-MS screening study with different rubber stopper extracts indicate different propensity of different materials to potentially modify amino acids in proteins

  3. Networking Lunch

  4. The Fate of Leachables During Biotechnology Drug Substance Downstream Processing

    Michael Jahn | Head Forensic Chemistry, Drug Product Services of Lonza

    • Clearance of organic and elemental model compounds in a mAb formulation was investigated for ultrafiltration / diafiltration and protein-A affinity liquid chromatography using trace analytical methods.
    • Clearance of organic model compounds was depending on their polarity (high clearance for polar compounds; low clearance for un-polar compounds). Elemental model compounds showed variable clearance.
    • Theoretical prediction of clearance factors for downstream processing steps based on ideal clearance behaviour leads to too optimistic estimation of the fate of leachables.

    Alicja Sobantka | Expert for Material Qualification of Octapharma

    • Extractable profiles of peroxide- and Platinum-cured silicone tubing used in pharmaceutical production are compared

    • Under comparable conditions Platinum-cured silicone tubing release significantly lower amounts of largely non-toxic extractables compared to peroxide-cured silicone tubing
    • Platinum-cured silicone tubing should be preferred over peroxide-cured silicone tubing, especially in high-risk manufacturing steps where no further reduction of extractables is expected such as sterile filtration and filling
