READ IN FULL
ZELNATE® is a bacterial produced plasmid DNA with a liposome carrier that stimulates the innate immune system in cattle. The innate immune system has been shown to provide a potent, rapid, nonspecific, protective response to infectious agents, such as those that can lead to Bovine Respiratory Disease (BRD). BRD is a serious condition that commonly causes lung lesions, reduced lung capacity, and mortality.
The freeze-dried (desiccate) product is packaged with two sterile diluents. The First Sterile Rehydrator (vial 1) is used to reconstitute the desiccate cake (vial 2), and then transferred to the Final Sterile Solution (vial 3) to achieve the proper concentration for administration.
ZELNATE® is indicated for use as an aid in the treatment of Bovine Respiratory Disease due to Mannheimia haemolytica in cattle 4 months of age or older, when administered at the time of, or within 24 hours after, a perceived stressful event.
IMPORTANT STORAGE CONDITIONS
Store refrigerated (2°C to 8°C).
DO NOT FREEZE.
In Study A, 3 to 4-month-old steers were randomly allocated to receive either ZELNATE® or a negative control (N=32 per group). On Day 0, each group of healthy calves was intramuscularly administered their respective treatment and challenged (intratracheally) with Mannheimia haemolytica. Lung lesion scores were obtained on Day 5. ZELNATE® significantly (p<0.05) reduced lung lesion scores compared to the control group (Figure A).1
In Study B, 3 to 4-month-old steers were randomly allocated to receive either ZELNATE® or a negative control (N=40 per group). On Day 0, each group was challenged (intratracheally) with Mannheimia haemolytica. Twenty-four hours post-challenge (i.e., Day 1), BRD morbidity was observed to be 67.5%. At this time, each group was intramuscularly administered their respective treatment (i.e., in the face of clinical BRD). Lung lesion scores were obtained on Day 5. Among calves that lived until Day 5, ZELNATE® numerically reduced lung lesion scores compared to the control group (data not shown). The cumulative incidence of death, associated with BRD, was 11.3%. The lung lesion scores among dead calves and those living to Day 5 were observed to be 55.3% and 17.6%, respectively. ZELNATE® significantly (p<0.05) reduced mortality compared to the control group (Figure B).2
Figure A: Average lung lesion scores between calves receiving either ZELNATE® or a negative control at the same time as an intratracheal Mannheimia haemolytica challenge. Lung lesion scores reflect those observed on Day 5 post-challenge.
* = statistically significant reduction (p<0.05)
Figure B: Cumulative incidence of mortality between calves receiving either ZELNATE® or a negative control 24 hours after an intratracheal Mannheimia haemolytica challenge. Mortality estimates reflect those observed from the Day of challenge (Day 0) to Day 5 post-challenge.
* = statistically significant reduction (p<0.05)
In conclusion, ZELNATE®, as a stand-alone therapy, has been shown to: 1) significantly reduce lung lesion scores, associated with BRD, when administered in the face of disease challenge (Study A), and 2) significantly reduce the risk of mortality when administered in the face of clinical BRD (Study B).
