Position Overview:

The Biostatistics Lead (Respiratory) will be a key member of several teams responsible for leading the development and conduct of statistical analyses contributing to the submission of publications and presentations arising from Sanofi-Genzyme-sponsored clinical studies, including Phase 3 and 4 studies, and exploratory analyses. This position supports Global Medical Affairs and marketed products, and the analyses will be mostly exploratory/post-hoc and oriented toward the needs of Respiratory (including, but not limited to, asthma and chronic rhinosinusitis with nasal polyposis) therapeutic area-related conferences, and health care provider and payer audiences.

The Biostatistics Lead will provide strategic input to cross-functional teams led by Medical Affairs who develop, select, and prioritize new exploratory/post-hoc analyses to meet specific strategic goals, and to teams who develop the abstracts and manuscripts. The ideal candidate will come with relevant disease area expertise to contribute significantly to the strategic planning for brand plans associated with medical and scientific communications. The successful candidate will furthermore be fully accountable for performing, QC'ing, and fine-tuning the chosen analyses, plus explaining and interpreting findings for internal colleagues, management, and external authors — this is a leadership and hands-on role. Statistical approaches and methods will require innovative and customized approaches. The Biostatistics Lead would also be responsible for the tracking documents and file archives for analysis plans, programming code, output, and associated reports. They will collaborate closely with internal statistics leaders and cross functional teams, as well as with alliance partner companies, as relevant, and the work of external biostatistics and programming contractors. As strong partnership across several stakeholders is key to the success of this role, it is important to have excellent communication skills and be fully comfortable in working with colleagues who are not co-located.

This is an exciting opportunity to be part of an active, high profile, high-impact Medical Affairs Team, and to perform interesting and complex statistical analyses in support of key products.

Key Responsibilities:

Major duties and responsibilities will include, but are not limited to, the following:

  • Understand existing studies, datasets, and analyses well enough to inform team members and guide strategy for future analyses. Harmonize statistical strategies and methods across departments.

This covers leadership across all activities including developing analysis specifications/plans, performing hands-on statistical programming when needed, and/or supervising external contractors responsible for analysis and programming. Analyses might be pre-planned or post-hoc, hypothesis testing or hypothesis generating, intended for dissemination or exploratory in nature. Present and/or explain findings to team members, internal managers, and/or external authors and experts. Validate inferences. Help craft listings and tables needed for abstracts, posters, slide decks, and manuscripts.

  • Co-lead forums/meetings when the focus is on analytical/data concepts, and support brainstorming and prioritization of the required post-hoc analysis. A critical need is to bring in disease area expertise and knowledge to these discussions, although these can be assimilated on the job.

  • Influence and contribute significantly to the strategic planning for brand plans associated with medical and scientific communications, aligning with the strategic imperatives.

  • Provide consultation, input, and guidance to cross-functional groups charged with development and submission of manuscripts, posters, slide presentations, and abstracts.

  • Establish and maintain collegial and collaborative relationships with cross-functional group members, Medical Affairs leaders, alliance partners, colleagues in worldwide affiliate countries, external medical writers, external experts, and authors.

  • Work with Publication Leads and team members to respond in a timely manner to journal editor and reviewer comments.

  • Review draft abstracts and manuscripts according to deadlines, and, when appropriate, serve as an author. In some cases, develop abstracts in close collaboration with external medical writers. Serve as the Publication Team’s expert on statistical methods sections.

  • As needed, support statistical analysis needs for dossier and/or response document submissions to HTA/payer bodies and independent therapeutic reviews (e.g. ICER).

  • Assign tasks and supervise the work of external contract statisticians and programmers, as well as internal resources.

  • As needed, provide consultant-level support for feasibility determinations for HEOR/HEVA studies, and consult regarding primary and secondary endpoints.

  • Maintain expertise in current statistical methods and standards relevant to pharma and biotech industry applications.
