Recommendation: The mycoplasma testing performed ---------------------------- appears adequate. There are no issues regarding mycoplasma testing to prevent approval of the BLA.

Review Summary 
On 08/07/07 I was asked to consult on the mycoplasma testing for the subject BLA. On 9/14/07 I initiated my review of the submission. On 9/21/07, I consulted with Ms. Clara Lin of OCBQ/DMPQ/PRB and Dr. Vladimir Chizhikov, OVRR/DVP/LMD regarding mycoplasma testing on -----------------------------------------------------. Consultation resulted in the conclusion that viral harvest (allantoic fluid prior to inactivation) is not required to be tested for mycoplasma (regulation and points to consider require mycoplasma testing for viral harvests made from in vitro cell cultures) for inactivated vaccines produced in eggs. Although mycoplasma can be cultured in allantoic fluid, the viral inactivation step would also inactivate mycoplasma. However, we agreed it is prudent to test the working viral seed (and also the master seed virus) for mycoplasma. CSL is performing mycoplasma testing ---------------------.
