Tech Transfer, Process Optimization & Troubleshooting
Seamless Tech Transfer, Sustained GMP Performance
Phosphorex ensures a smooth transition from development to GMP manufacturing through our well-established tech transfer playbook. Because we design the formulation and process, we offer critical knowledge that supports our clients and GMP manufacturers in optimizing GMP processes and providing expert troubleshooting to maintain performance, reproducibility, and regulatory confidence throughout the full product lifecycle.
7-Point Tech Transfer Playbook
Successful tech transfer to a GMP manufacturing partner requires more than documentation; it demands structured knowledge transfer, risk mitigation, and technical continuity. The Phosphorex 7-Point Tech Transfer Playbook preserves formulation intent, protects critical quality attributes, and ensures seamless transition to GMP manufacturing with confidence, reproducibility, and regulatory alignment.

Ongoing Process Optimization & Troubleshooting
Process performance does not end at tech transfer. Because Phosphorex designed the formulation and process, our team often collaborates with GMP manufacturers to refine operating parameters, improve robustness, and optimize yield, cycle times, or downstream efficiency. If deviations occur, we can provide rapid root cause analysis, CQA impact assessment, and data-driven corrective strategies to restore consistency while preserving regulatory compliance and product integrity.

THE PHOSPHOREX DRUG DELIVERY ENGINE IN PRACTICE
Clinically Relevant Downstream Process Optimization
Problem
An ionizable lipid chemistry innovator company developing novel LNP systems was interested in developing an effective, scalable downstream process to reliably maintain LNP critical quality attributes. Due to the unique formulation composition, the LNP demonstrated shear sensitivity in standard tangential flow filtration (TFF) protocols.
Solution
Phosphorex optimized the quality of the novel, shear-sensitive LNP formulation after mixing process scale-up and transfer of batch downstream purification from dialysis to tangential flow filtration (TFF) by:
- Determining the optimal TFF membrane chemistry, molecular weight cut-off, and surface area
- Determining the optimal concentration factor before diafiltration
- Optimizing the transmembrane pressure, feed pump flow rate, and column loading
- Optimizing the downstream buffer pH and ionic strength
Outcome
The LNPs resulting from the optimized TFF method demonstrated>90% cargo yield, a mean particle size of 96 nm, a low PDI of 0.11, and an encapsulation efficiency of 92% following successful concentration to the target range. The final TFF method was qualified for batch fabrication to support an NHP study.
