Workplan #3
RTC Process Development and Analytical Methods WORK PLAN SUMMARY
Objective
Determine operating conditions for RTC mixing and filtration that provide a robust process for preparing sterile, homogeneous ready-to-coat (RTC) formulation. Following these experiments, the process and parameters for preparing RTC should be finalized.
Some method development efforts are also addressed below.
Background
[*]
Process efficiency is currently about [*]%. Variations in filtration media and devices will be investigated to improve this number.
Scope
Observed response variables for the mixing experiments are average content, variance of the content, and viscosity. Two mixing methods will be investigated: [*] (the current method) and [*], a [*] method [*]. For [*], three times ([*], [*], [*] min) prefiltration and four times ([*], [*],[*],[*] minutes) postfiltration will be tested. For [*], three times will be investigated prefiltration ([*], [*], [*] minutes) and four times postfiltration ([*], [*], [*], and [*] minutes). To investigate the effect of the RTC concentration, mixing will be performed with [*]% and [*]% bulk drug substance (w/w). The current manufacturing process uses [*]% w/w.
Materials
[*] g BA058
Miscellaneous lab supplies
* Confidential Treatment Requested by the Registrant. Redacted Portion Filed Separately with the Commission.
Procedure
For each mixing technique, the prefiltration experiments will be performed. The best prefiltration mixing time will be used for the postfiltration experiments. The procedure will be repeated for the two concentrations of BA058.
The average and variance of the content will be determined by taking multiple samples from each mixing experiment and assayed using a validated HPLC method (Method-07-001836). Viscosity of the RTC following each experiment will be tested using a Rheosense m-VROC.
Each experiment will use [*] mL of RTC ([*] g of bulk drug substance). [*]. The [*] g figure is considerably larger than previously quoted. The previous quote assumed material could be saved by using the RTC from the mixing experiments to begin the coating process experiments. Of course, unused RTC from this work will be saved for future use.
To determine the optimal approach to sterile filtration, a solution of BSA will be prepared with a viscosity similar to that of the current RTC. This solution will be used to test filtration setups for easy of use and efficiency. Once a suitable configuration is found, it will be tested by sterile filtering RTC and checking for changes in viscosity, purity, and content.
