In a presentation at the American Society for Microbiology’s annual meeting, the oral administration of a commercially available probiotic bacterial strain was found to improve dry eye disease in an animal model.

The company noted tanfanercept did not demonstrate statistical significance in either of the primary outcome measures of improvement in central corneal staining score or in improvement in Eye Dryness Score assessed at week 8 in subjects with dry eye disease, compared to vehicle. However, tanfanercept did demonstrate a highly statistically significant improvement on one of the secondary outcome measures, Schirmer testing of tear volume.
