Senior Principal Scientist, DMPK

Who We Are:

Cogent Biosciences is a publicly traded biotechnology company focused on developing novel precision therapies to treat a broad range of patients with unmet medical needs. Cogent’s lead program, bezuclastinib, is designed to selectively and potently inhibit exon 17 mutations found within the KIT receptor tyrosine kinase, including KIT D816V. KIT D816V is responsible for driving a rare and serious condition called Systemic Mastocytosis, and exon 17 mutations are also found in patients with gastrointestinal stromal tumors (GIST), a type of cancer with strong dependence on oncogenic KIT signaling. Bezuclastinib has exhibited promising initial data across all three trials: APEX in AdvSM, SUMMIT in NonAdvSM and PEAK in GIST, including an encouraging safety profile across 600+ patients in single-agent and combination dosing.

The Role: This position works with a fast-paced team in Drug Discovery and Development to provide scientific direction and strategy across the DMPK department by being an expert in the design, execution, and interpretation of in vitro ADME and in vivo PK experiments. The successful candidate will utilize their strong knowledge of ADME/PK to collaborate cross-functionally with in-house medicinal chemistry, pharmacology, and toxicology teams and outside CROs, functioning as the DMPK lead for small molecule drug discovery projects. Critical thinking, independence, and innovative problem-solving are hallmarks of the position.

Responsibilities:

• Lead and implement evolving DMPK strategies within the department, program team, and work across disciplines to advance small molecule oncology therapeutics toward the clinic.

• Apply literature, cutting-edge techniques, and critical thinking to solve problems within DMPK with high independence.

• Design, conduct, and supervise the analysis of in vitro and in vivo DMPK studies.

• Interpret bioanalytical and PK results and perform NCA PK modeling.

• Develop LC-UV-MS/MS analytical methods to quantitate compounds, metabolites, and biomarkers in biological fluids.

• Manage interactions with CROs to support program team objectives.

• Conduct written and verbal scientific presentations to project teams.

• Prepare data and reports as needed for dose prediction, IND, and other regulatory needs.

• Good written and oral communication skills, including timely electronic laboratory notebook entries, group presentations, and meeting administration.

• Proven work ethic, competence, enthusiasm, problem-solving, and team focus.

Qualifications:

Education:

PhD in Drug Metabolism, Pharmaceutical Sciences, Toxicology, Pharmacokinetics, Pharmacology, Biochemistry, Biology, Chemistry or other relevant field. Other non-PhD degree applicants with similar area of focus will be considered with significant years of industrial experience and demonstrated breadth of DMPK knowledge.

Experience:
• PhD in a scientific discipline, or MS with 8 years of experience, or BS with 10 years of experience.
• Expertise performing quantitative bioanalysis in various biological matrices using LC-MS/MS instrumentation.
• In vitro ADME exposure, in vivo PK and PK modeling.
• Working together with a project team to identify clinical candidates a plus.
• Contributions to the preparation of FDA regulatory documents a plus.

Knowledge/Skills/Abilities:
• Critical thinking, problem solving, independence, cross-discipline awareness, multi-tasking in a fast-paced environment.
• Strategic thinking to implement effective tactics quickly.
• Scientific and technical knowledge around pharmacokinetics, formulation, drug metabolism, drug transporters and enzyme kinetics.
• Working in-depth knowledge of ADME/DMPK and relationships of in vitro and in vivo assays
• Strong knowledge of LC-MS/MS instrumentation, troubleshooting, method development and analysis of biological fluids and tissues, preferably on Sciex QQQ platform.
• Non-compartmental PK modeling, metabolite identification, in vitro ADME and in vivo assay development, drug formulation, project presentations, meeting supervision, and report writing.
• Human dose prediction, process automation via software or robotics is a plus.

Salary Range:

$150,000 - 175,00 USD

Target Bonus: 15%

Exact compensation will vary based on skills, experience, and location.
