— WHY IS THIS NEEDED?
Teriparatide — recombinant human parathyroid hormone (1-34) for osteoporosis treatment:
• Peptide nature makes it sensitive to degradation (chain truncation) and oxidation (methionine).
• Peptide aggregation can cause immune response (antibody formation), reducing efficacy and safety.
• Administered subcutaneously, often in multi-dose formats, so strict sterility and endotoxin control is mandatory.
• Presence of preservative (meta-cresol) must be in strict range to ensure stability during multi-use.
⚠️ CRITICAL:
• Peptide Content: 0.95–1.05 mg/mL
• Potency: 2500–3500 IU/mg
• Related Peptides (Impurities): ≤ 1.0%
• Oxidized Forms: ≤ 0.5%
• Aggregates/Dimers: ≤ 0.5%
• Endotoxins: ≤ 50 EU/mg (or stricter)
• Sterility: No growth
• Appearance: Clear, colorless
⚠️ Note: Utility focuses on peptide drug specifics. Control of truncated forms (related peptides) and aggregates is a Key Quality Attribute (CQA). High aggregate levels are unacceptable due to immunogenicity risk. Sterility and low endotoxin levels are critical for parenteral administration.

10. QA/QC, CSV and change control
- Before production use, the client records executable version, checksum, specification/monograph version, test CSV, expected JSON and IQ/OQ results.
- Column names must not be changed without updating the validator and test scenarios.
- The source CSV, output.json and utility version should be stored together as an evidence package.
- Any change in control rules must go through change control and repeated OQ scenario verification.
