Is any phase 4 ongoing study for an alternative manufacturing process for privigen hereafter referred to as the high yield process?

I don’t have enough provided information to confirm whether any Phase 4 study is currently ongoing for Privigen (human immune globulin) using an alternative manufacturing process described as the “high yield process.”

If you share either:
- the study registry identifiers (e.g., ClinicalTrials.gov NCT number(s)), or
- the sponsor/company name and the exact study title wording you’re referring to,

I can verify whether it is Phase 4 and whether it specifically uses the high-yield manufacturing process.
