Primary Responsibilities Include:

Clinical Development Strategy & Study Leadership:

• Serve as a clinical science lead or key clinical science contributor for assigned studies, partnering with the study medical director to support study strategy, design, execution, data interpretation, and reporting.
• Provide scientific input into study design, patient population, eligibility criteria, endpoints, biomarkers, assessments, visit schedules, and data collection strategies to ensure trials are scientifically sound, operationally feasible, and aligned with program objectives.
• Interpret emerging clinical data and translate findings into clear recommendations for study conduct, clinical development strategy, internal governance discussions, regulatory interactions, and external scientific communications.
• Maintain current knowledge of rare disease, neuromuscular disease, genetic medicine, oligonucleotide therapeutics, clinical trial innovation, regulatory expectations, competitive developments, and relevant scientific literature.

Clinical Trial Execution & Cross-Functional Collaboration:

• Partner closely with Clinical Operations, Biostatistics, Data Management, Pharmacovigilance, Regulatory Affairs, Translational Medicine, Medical Affairs, Quality, CROs, vendors, and other stakeholders to support high-quality study execution.
