AboutParabilisMedicines

ParabilisMedicines is a clinical-stage biopharmaceutical company dedicated to creating extraordinary medicines for patients with serious diseases by unlocking biologically important targets longconsidered undruggable.The company has pioneered a new class of alpha-helical peptides – Helicons™ – capable of modulating intracellular proteins that have historically been beyond the reach of conventional medicines. The company’s lead investigationalmedicine,zolucatetide, is the first and only direct inhibitorof theβ-catenin:TCFinteraction,a central node in theWnt/β-catenin pathway that haseluded drug developersfor decades.Zolucatetideis being evaluated in the clinic across multipleWnt/β-catenin-driven diseases, including desmoid tumors, familial adenomatous polyposis (FAP)anda rangeofothersolid tumor indications. Beyondzolucatetide,Parabilisis advancing additionalHelicon-basedprograms focused on other challenging targetswhere we believeourmedicines could have life-altering impact.

You will partner closely with medicinal chemists, pharmacologists, toxicologists, and external CRO partners to integrate ADME, PK, and PK/PD insights, proactively identify and mitigate development risks, and advance novel therapeutics from early discovery through development candidate nomination.

Key responsibilities:

• Provide strategic leadership for peptide DMPK across multiple discovery programs, establishing ADME strategy and ensuring alignment with program milestones, development objectives, and broader portfolio priorities.
• Lead the design, interpretation, and integration of in vitro and in vivo ADME/PK studies to drive lead optimization, development candidate nomination, and progression into IND-enabling development.
• Serve as a DMPK subject matter expert and strategic partner to medicinal chemistry, pharmacology, toxicology, and other cross-functional functions, integrating DMPK data to influence chemical design and prioritize novel chemical matter with favorable drug-like and translational properties.
• Identify and proactively address key DMPK risks, knowledge gaps, and development challenges, establishing fit-for-purpose strategies to enable program progression.
• Provide scientific oversight of external CROs and partners, ensuring high-quality execution of DMPK studies within program timelines and budgets.
• Present DMPK strategies, integrated data assessments, human translation considerations, and risk/benefit recommendations to project teams and senior leadership to inform key investment and development decisions.
• Provide DMPK leadership for regulatory strategy and submissions, including IND/NDA, Investigator Brochures, briefing documents, and responses to regulatory authorities.
• Co-lead the development and implementation of AI-enabled DMPK workflows and digital solutions to streamline operations, accelerate data analysis and integration, and enable faster, data-driven decision-making across discovery and development programs.
