Core Responsibilities

Primary Functions

Lead the design and authoring of clinical study protocols, informed consent forms, and study-specific operational documents; ensure scientific rationale, objectives, endpoints, inclusion/exclusion criteria, and statistical considerations are clear, feasible, and aligned with the development plan.
Own clinical development strategy and provide input to the clinical development plan (CDP) by synthesizing preclinical and clinical data, therapeutic landscape, and regulatory expectations to define trial designs that de-risk development and optimize clinical readouts.
Serve as the clinical scientific lead for sponsored trials, acting as the primary scientific liaison to cross-functional teams (regulatory, safety, biostatistics, data management, pharmacovigilance, medical affairs, CMC) to align on objectives, analysis plans, and submission strategy.
Provide end-to-end trial oversight for Phase I–III studies, including study start-up, site selection/qualification, enrollment monitoring, protocol compliance, interim analyses, and study close-out activities to ensure timelines and quality metrics are met.
Manage CRO selection, contracting, and oversight activities: develop SOWs, negotiate deliverables, implement governance, conduct status & quality reviews, and ensure CRO performance meets company expectations and regulatory requirements.
Lead risk-based monitoring and quality oversight activities, review monitoring reports and clinical data trends, and implement corrective and preventive actions (CAPA) to maintain data integrity and patient safety.
Draft, review, and finalize clinical study reports (CSRs), integrated summaries, and clinical sections of regulatory submissions (IND/IMPD, CTA, NDA/MAA) in collaboration with regulatory and medical writing teams.
Oversee safety signal assessment and SAE reporting workflows in partnership with pharmacovigilance; contribute clinical context for safety narratives, benefit-risk assessments, and labeling discussions.
Collaborate with biostatistics to develop SAPs, randomization schemes, sample size justifications, and interim analysis plans; interpret statistical outputs and incorporate findings into clinical strategy.
Lead protocol amendment planning and implementation, providing scientific rationale, impact assessments, and communication plans to sites, regulators, and stakeholders.
Develop and execute site engagement and enrollment strategies: conduct feasibility assessments, support investigator meetings, provide scientific training to sites, and monitor site performance to optimize recruitment and retention.
Prepare and present program status updates, clinical development rationales, and regulatory strategies to internal governance committees, executive leadership, and external advisory boards.
Drive clinical data review and medical monitoring activities: perform medical review of adverse events, queries, and clinical endpoint adjudication to ensure robust safety and efficacy assessments.
Support product positioning and clinical evidence generation by designing sub-studies, biomarker analyses, PK/PD studies, and exploratory endpoints that add value to regulatory and payer discussions.
Mentor, coach, and develop junior clinical scientists and CRAs; define performance objectives, provide feedback, and lead training on protocol, GCP, and clinical development best practices.
Ensure compliance with global regulatory requirements and Good Clinical Practice (GCP); prepare for and support regulatory inspections, clinical trial audits, and remedial action plans when required.
Participate in commercial and lifecycle planning discussions by providing clinical evidence strategy, post-marketing study design input, and real-world evidence opportunities to support product adoption.
Lead cross-functional troubleshooting during operational or scientific challenges (e.g., slow enrollment, data quality issues, unexpected safety findings) and implement mitigation plans to preserve study integrity and timelines.
Contribute to scientific communication efforts including abstracts, posters, manuscripts, and congress presentations; collaborate with medical affairs and publication teams to disseminate study results.
Develop and manage study budgets and timelines for assigned programs; monitor cost drivers, support forecasting, and escalate budget or resource risks appropriately.
Evaluate and integrate novel trial designs (adaptive, basket, umbrella, decentralized trials) and digital health technologies to increase efficiency, recruitment, and patient-centricity where appropriate.

Secondary Functions

Support ad-hoc scientific requests from business development, licensing, and strategic partnerships by providing clinical input, feasibility assessments, and due diligence summaries.
Contribute to the development and maintenance of standard operating procedures (SOPs), templates, and tools to streamline clinical study execution and ensure consistency across programs.
Participate in vendor qualification processes for labs, central readers, imaging vendors, and biomarker partners; ensure assay validity and vendor compliance.
Assist in investigator selection and site contract negotiations by providing clinical criteria, feasibility insights, and oversight of investigator brochures and study-specific training materials.
Collaborate with data management and clinical operations to define data cleaning strategies, query resolution processes, and ensure timely database lock readiness.
Engage with patient advocacy groups and investigators to capture patient-centric endpoints and improve recruitment materials and informed consent processes.
Support post-marketing commitments and phase IV study designs, including observational studies and registries, to meet regulatory and commercial evidence needs.
Participate in cross-functional process improvement initiatives to reduce cycle times (e.g., protocol development, IND submission preparedness, study start-up).
Facilitate investigator meetings, steering committee meetings, and data safety monitoring board (DSMB) interactions by preparing agendas, presentations, and scientific briefing materials.
Monitor evolving scientific literature and competitive landscape to refine trial hypotheses, comparator selection, and endpoint relevance.
