`
`This week has been a great week for L-715:
`•definitive proof of concept was achieved in the Phase IB study (this is restricted and confidential information)
`•Cannpaign I was completed, producing a grand total of 95 kg of L-715 after 10 months of constant piloting (pending
`release assays)
`.Crystallization/drying improvements led to delivery of large (50 um) particles to Pharnn R&D for further development of
`the direct compression formulation
`
`Lots of people not included on this mailing list need to be thanked for the success of the campaign as a whole.
`Regarding crystallization/drying improvements between PPB#1-2 and PPB#2/3-2 I would like to make a few
`acknowledgments. First, thanks to Beth Fisher and Al Wieczorek who were instrumental in the design and execution of
`the UOPS drying studies. Thanks are also due to the SSO facilities staff (particularly Dan, Mike and Steve Van Cleat) for
`d usting the cobwebs off of DR-90G. Without the Sumnnix in working order in the SSO we wouldn't have been able to
`support Pharm R&D in their development of the optimal formulation for Phase IIB. Thanks are also due to our Physical
`Measurements colleagues who analyzed numerous PSD, TG and XRD samples this week and last.
`
`I have enclosed our weekly for further discussion of this week's drying studies and PP performance.
