Location: Barcelona - Spain (3 days working from the office and 2 days working from home)

This is what you will do:

As a member of thefast-pacedImmunogenicity Sciences group, you will be involved indevelopingstrategies to address scientific and regulatory priorities that should be integrated to understand and manage immunogenicity-related risks for the successful development ofa diverse pipeline ofbiotherapeutics.This will involveevaluating immunogenicitydata and assessing immunogenicityrisk forT-cell engagers(TCE)and cell and genetherapy programsduring preclinical and clinical phasesand where applicable devising mitigation strategies.Working closely with multiple departmentsacross Alexion and AstraZenecain a matrixedenvironment,you willcoordinate immunogenicity efforts to understand the impact of immunogenicity in non-clinical and clinical settings.

TheImmunogenicitySciencesDirectorwill be part of atalented, creative, collaborative team which is essential for the success of Alexion’s diverse portfolio of clinical trials. The Immunogenicity Sciences group is a globaldepartmentwithin the Clinical development, Regulatoryand Safety(DRS)organization, with colleagueslocatedin US,Canadaand Spain. The Immunogenicity Sciences groupmaintainshigh standardsof bioanalytical, immunology and immunogenicity excellence, leadership, quality, and compliance.

Strong leadership to create an environment and culture that constantly ensures compliance with internal procedures and processes set up by the Immunogenicity Sciences group and with current guidance documents from the FDA, EMA, and other regulatory agencies will be essential. The Director ofImmunogenicity Sciencesis accountable for interactions with regulatory agencies (especially EMAand MHRA) for specific issues on Immunogenicityassays, data interpretation, and for the Immunogenicity portions of IND, IMPD NDA/BLA/MAA, IB,study protocols, SAPs & CSRs, or other regulated documents. The leader willparticipatewith the rest of theclinical assetteam in devising strategies forregulatoryinteractions.

This individual will collaborate closely with Global Project Team Leaders(GPTLs), theTherapeutic-Area specific Clinical and Quantitative Pharmacology leaders,PatientSafety, Toxicologyand Bioanalytical to ensure prioritization are aligned with R&D priorities. Oversight, coaching, and mentoring of clinical team staff and Immunogenicity Sciences projectleadsfor interacting with Global Project Team Leads (GPTLs) and Clinical Project Leaders (CPLs) to enable Immunogenicity support for clinical trials will be essential. This roleis strategic andhas high visibility and high impact, with the ability to grow withinthe Global Immunogenicity Sciences group.

You willbe responsible for:

  • Leading staff for the development of immunogenicity strategies for biologics, siRNA, peptides, gene therapy, cell therapy, TCEand emerging therapeutic modalities, including composition and review of Immunogenicity portions of IND, IMPD NDA/BLA/MAA, IB study protocols, SAPs & CSRs, or other regulated documents.
