Role Summary

Senior Scientist, Translational Biomarkers will design, develop and validate biomarker assays to support clinical safety and efficacy studies; ensure regulatory compliance with ICH Q2 guidelines; manage transfer and validation of biomarker assays at CROs; contribute to translational plans addressing MOA, pharmacokinetics and pharmacodynamics; collaborate with Clinical Operations, Data Management and Biometrics to advance data acquisition and analyses; oversee scientific projects and potentially supervise associate scientists.

Responsibilities

  • Design, develop, validate and execute robust fit-for-purpose clinical biomarker assays to support secondary and exploratory endpoints in clinical safety and efficacy studies.
  • Ensure biomarker methods are compliant with ICH Q2 guidelines and meet regulatory standards.
  • Manage the transfer, bridging and validation of biomarker assays at CROs.
  • Contribute to biomarker plans and strategies for addressing key translational questions such as MOA, pharmacokinetics and pharmacodynamics of drug candidates.
  • Collaborate with external partners, Clinical Operations, Clinical Data Management and Biometrics to advance data acquisition and analyses of clinical trial data.
  • Analyze, interpret, prepare and present data summaries, communicate next steps and provide recommendations to internal teams and stakeholders.
  • Contribute to regulatory document preparation such as clinical protocol, regulatory responses, and submissions.
  • Identify, evaluate and integrate new technologies to support evolving translational biomarker strategies.
  • Write and review SOPs, technical protocols and reports.
  • May supervise associate scientists and support their professional development.

Qualifications

  • PhD in immunology, immuno-oncology, molecular and cellular biology or related field.
  • 5+ years of biomarker experience in the pharmaceutical industry.
  • Strong understanding of various technology platforms and datasets used to support clinical biomarker assays for early to late-phase clinical trials.
  • Strong technical expertise in developing, validating and implementing clinical biomarker, immunological, molecular and gene expression assays including multi-parameter flow cytometry (>12 colors), immunohistochemistry (IHC), droplet digital PCR (ddPCR), RNA isolation/sequencing, gene expression with platforms such as Nanostring.
  • Subject Matter Expert (SME) on validation of analytical methods per ICH Q2 guidelines.
  • Strong data analysis capabilities of high-dimensional data using FlowJo or data packages such as Cytobank; knowledge of R and/or Python is preferred.
  • Experience managing CROs and ensuring high-quality, timely delivery of biomarker data, with understanding of ICH/GCP and regulatory requirements.
  • Strong problem-solving skills and ability to independently oversee scientific projects, rigorously analyze and interpret scientific data with attention to detail.
  • Effective communication skills, with the ability to present complex data to diverse audiences.
  • Experience working in a GCLP regulated environment and extensive knowledge of GLP/GCP compliant studies.
