Responsibilities:

• Conduct analysis and characterization of peptides using various analytical techniques.
• Ensure that all critical analytical parameters for peptides — such as purity, identity, and content — are properly defined and validated.
• Confirm the use of appropriate, validated methods for batch verification, including HPLC, LC-MS, and NMR.
• Oversee stability studies according to ICH guidelines to ensure the peptide maintains integrity in its solid form.
• Set and maintain acceptance criteria for release testing, aligned with regulatory and internal quality standards.
• Review and approve the CMO’s manufacturing processes, including:

          Use of excipients, if applicable.

• Define Critical Quality Attributes (CQAs) and Critical Process Parameters (CPPs) relevant to solid-state peptides — such as residual solvents, moisture content, and solid form stability.
• Ensure appropriate controls are in place to detect impurities or degradation, such as aggregation, oxidation, deamidation, and racemization.
• Review and approve the analytical methods used by the CMO to ensure they meet regulatory and scientific standards.
• Oversee identity testing (to confirm correct amino acid sequence) and impurity profiling.
• Ensure that all testing and controls at the CMO are performed under GMP-compliant conditions.
• Participate in batch record review and deviation management, including the evaluation of borderline or out-of-specification results.
• Monitor ongoing trend analysis to identify potential quality or process issues early.
