The Role

We are seeking a strategic, hands-on Associate Director, Regulatory Affairs to lead regulatory project teams and submission activities across assigned development programs. We seek a candidate who thinks innovatively and has deep expertise in early development (Pre-IND/IND) and Phase II proof-of-concept (PoC) strategy, coupled with a strong foundation in global regulatory planning for psychiatry and neurology therapies. This role requires equal emphasis on shaping preclinical-to-clinical transitions and aligning late-phase pathways towards approval, ensuring seamless integration of regulatory requirements across the development lifecycle.

Qualifications:

Bachelor’s degree required; advanced degree in a scientific discipline preferred.

7+ years in global regulatory affairs, including expertise in early development (Pre-IND/IND) and late-phase strategy for CNS therapies.

Relevant hands-on experience leading IND/CTA and/or NDA/MAA submissions.

Proven success in:

Leading Pre-IND or INTERACT meetings and IND/CTA submissions for psychiatry/neurology programs.

Designing Phase II PoC studies with validated endpoints.

Preparing Phase III-ready protocols and health authority interactions (FDA EOP2, scientific advice, Pre-NDA).

Deep knowledge of global regulatory frameworks and eCTD submission standards.

Practical, applied fluency in FDA/EMA neuroscience guidelines and ICH standards.

Proficiency with publishing and document management tools (e.g., Veeva, Smartsheet, Office Timeline Pro)
