Will the library be available to everyone?
The agency does not plan to share the library at this time. If industry and the agency see value in sharing the library in
the future, FDA will conform to any provisions in the MTAs.
Will others be able to contribute to the spectral library?
FDA prefers to obtain excipients directly from manufacturers or distributors to be certain of their identity and provenance
of the manufacturer and/or manufacturing site to minimize the possibility that a contaminated or subpar quality excipient
is included in the library. As far as contributing spectral entries into the spectral database, FDA will not be accepting
How will the materials be used and/or evaluated?
Both Raman and NIR spectra of the excipients received will be generated without further testing or qualification of the material.
As the scope of this effort is to establish a spectral library database, FDA does not plan to perform quality testing.
Would there be a time factor for the samples (i.e., would the manufacturer need to send samples every year)?
For most samples, this step would not be required. However, manufacturers could send new samples if they felt a process or
raw material change could affect the spectrum of their material.
