| Cleavage & Disulfide Folding | TFA cleavage cocktail optimization, scavenger screening, and air/guided oxidative folding condition development. |
| Early Purification & Counterion Screening | Preparative RP-HPLC method screening and initial counterion selection (acetate vs. chloride). |
| IND-Enabling CMC Support | Racemization profiling, deletion peptide mapping, forced degradation, and IND CMC package prep. |
| Clinical Phase I | Early Clinical Manufacturing |
| GMP Upstream & Cleavage | Tech transfer, scale-up of SPPS cycles, raw material amino acid qualification, and crude peptide isolation. |
| GMP Purification & Salt Exchange | Multi-step RP-HPLC purification, TFA-to-acetate counterion exchange, and batch lyophilization execution. |
| Analytical Release & Control | LC-MS identity confirmation, chiral HPLC amino acid analysis, residual TFA testing, and GMP release. |
| Clinical Phase II | Process Characterization & Optimization |
| Process Robustness & QbD | DoE studies on coupling temperature, racemization risk points, resin substitution rates, and cleavage parameters. |
| Purification & Isolation Scale-Up | Optimization of column loading capacity, solvent recycling strategy, and isolation/lyophilization parameters. |
| Reference Standards & Characterization | Primary peptide reference standard qualification, secondary structure assessment (CD/NMR), and stability studies. |
| Clinical Phase III | Registration Readiness |
| Commercial Process Lock | Finalization of SPPS batch parameters, resin/reagent specs, folding limits, and Master Batch Records. |
| Analytical Method Validation | ICH Q2 validation for RP-HPLC purity, chiral purity, TFA/acetate assay, MS identity, and bioburden/endotoxin. |
| Regulatory & Raw Material Security | Critical amino acid building block supplier qualification, CTD Module 3 authoring, and NDA/MAA filing. |
| Commercialization | Process Validation & Launch |
| Process Performance Qualification | PPQ campaign execution (≥3 consecutive batches), aggregation tracking, and process consistency validation. |
| Commercial Supply & Testing | Routine commercial release, lyophilization capacity validation, cold-chain distribution, and launch readiness. |
| Lifecycle Management | Continued process verification (CPV), yield improvement, green chemistry solvent optimization, and post-approval updates. |
