1. PRODUCT IDENTIFICATION
pPL657 rDNA construct in the glycoprotein galactosyltransferase alpha-1,3 gene (GGTA1) in the hemizygous and homozygous GalSafe®1 lineage of domestic pigs (Sus scrofa domesticus) resulting in undetectable endogenous galactose-alpha-l,3-galactose sugar residues on biological derivatives of the homozygous GalSafe® lineage that are intended to be used as sources of food or human therapeutics including excipients, devices, drugs, or biological products.
- 1
- GalSafe® is the registered tradename for Revivicor’s lineage of pigs and is not itself subject to FDA approval. Rather, the regulated article subject to FDA approval is the intentional genomic alteration (pPL657 rDNA construct), which is contained in the GalSafe® lineage of pigs.
2. WARNINGS AND PRECAUTIONS
2. Food Safety Warnings:
a. To mitigate the potential development of bacterial resistance to aminoglycoside antimicrobial drugs, GalSafe® pigs should not be treated with an aminoglycoside.
b. Other Warnings:
The GalSafe® lineage must only be housed in physically contained facilities specified in the approved application.To report suspected adverse events or request other technical assistance, please contact Customer Support at 540-961-5559 or www.revivicor.com. For additional information about adverse drug experience reporting, contact FDA at 1.888.FDA.VETS or www.fda.gov/reportanimalae.
3. TARGET ANIMAL SAFETY
Data from the GalSafe® lineage demonstrated a lack of adverse effects for the pPL657 rDNA construct in the GalSafe® pigs vs. comparator pigs without an intentional genomic alteration (IGA).
With respect to reproductive outcomes, litter characteristics of GalSafe® pigs were evaluated on a quarterly basis using data collected during 2012-2018. Quarterly means, with standard deviations, and ranges are provided in Table 1 below:

In a study to compare physiological endpoints in GalSafe® pigs vs. comparator pigs (comparators) without an intentional genomic alteration (IGA), blood samples were collected for evaluations. No differences between GalSafe® and comparators were evident based on the following evaluations: serology, CBC (complete blood count) and comprehensive blood chemistry. Values were within expected physiological ranges.4. EFFECTIVENESS
Multiple generations of the GalSafe® line have demonstrated genetic consistency as established through genetic tests for the presence of the pPL657 rDNA construct, pPL657 rDNA sequence fidelity and pPL657 rDNA construct integration site consistency. For multiple consecutive generations, phenotypic consistency has been established based on the undetectable levels of galactose-alpha-1,3-galactose sugar residues on biological derivatives of homozygous GalSafe® pigs.
