Job Opportunity

Scientific Director, Pharmaceutical Preformulation

Location: San Diego, CA, US
Department: Technical Operations / CMC
Employment Type: Full Time
Reference Number: 1693382

Job Description Summary

The Scientific Director, Pharmaceutical Preformulation, will be responsible for leading technical activities related to preformulation and developability assessments of new molecular entities (NCE's), and selecting formulation approaches for early-stage clinical trials (FIH, Phase1-2). The scope includes evaluation of novel or established drug-delivery, formulation, or manufacturing process technologies for overcoming product developability challenges (e.g. solubility, permeability, stability, ADME). He/she will serve as a subject matter expert in areas related to preformulation and drug delivery platforms for small-molecule therapeutics.

Your Responsibilities:

  • Lead preformulation activities internally and/or at external contract research organizations. Scope includes oral solid dosage forms as well as parenterals.
  • Develop standard approaches for preformulation screening of NCE's, and design decision-trees to guide formulation selection decisions. Design effective strategies for developing drug product via conventional methods or drug delivery / process technology approaches.
  • Design and implement efficient studies & DOE's to assess product developability risk and demonstrate formulation viability (e.g. screening & optimization of pH, excipient levels, stabilizers).
  • Engage with discovery research & pre-clinical teams for biopharmaceutics assessment of NCE's, pharmaceutical candidate optimization activities, and product developability evaluations. Support preclinical team, as needed, in the development of optimal formulations for toxicology studies.
  • Engage with API process chemistry and material science teams to ensure drug substance with appropriate physico-chemical properties is advanced for product development. Support material characterization efforts - polymorphic form, mechanical attributes, particle size assessment, physicochemical stability, etc.
  • Work cross-functionally with discovery research, clinical, process chemistry, analytical, regulatory, and related teams to achieve program objectives. Author / review study protocols, technical reports, and relevant sections of regulatory documents (e.g. IND, IB, IMPD).
  • Maintain up-to-date scientific knowledge through regular literature review and participation in conferences. Leverage external publications and relevant industry benchmarking metrics to streamline organizational early-to-late stage product development workflows.

What is Required:

  • Doctorate (Ph.D.) or Masters (M.S.) degree in Pharmaceutics, Pharmaceutical Science, Physical Chemistry, or a related discipline, with 10+ years of relevant industry experience, or BS with 15+ years of relevant experience.
  • High competency in preformulation, biopharmaceutics and physicochemical characterization aspects pertinent to small-molecule drug product development.
  • Strong scientific understanding of principals related to physical chemistry and pharmaceutics - including pKa, LogP/LogD, solubility (e.g. pH-solubility profile, solubilization, cosolvents), solid-state (e.g. polymorphism, crystal habit, size, surface characteristics, mechanical properties), molecular optimizations (e.g. salt, hydrate, solvate, co-crystals), degradation pathways (e.g. hydrolysis, oxidation, temperature, light).
  • Adept in material characterization techniques including x-ray diffractometry, spectroscopy (e.g. FTIR, Raman, NMR, MS, UV/VIS etc.), particle and powder characterization, dynamic vapor sorption, mechanical and thermal analyses.
  • In-depth knowledge of proprietary and non-proprietary formulation and process technology approaches for compound enablement (e.g. solubilized formulations, spray dried systems, amorphous drug in polymeric matrices, modified release formulations, permeation enhancers, liposomes, etc.).
  • Experience working with drug discovery & pre-clinical teams to assess product developability. Hands-on experience with GastroPlus or related tools is a plus.
  • Ability to independently design and implement study plans internal or external CDMO sites. Capability to adapt and improvise based on real time results and findings.
  • Exceptional written and verbal communication skills. Ability to lead project teams.
  • Experience in authoring and review of regulatory submissions (e.g. IND, IB, IMPD), protocols and related development reports. Strong understanding of ICH, cGMP, worldwide regulatory requirements and industry best practices.
  • Ability to travel up to 20% domestically and internationally.
