New FDA Authorization Broadens Zoetis Screwworm Treatment Options
By Chelsea Dinterman
Zoetis Inc. has received conditional approval for the 100 mL vial size of its Dectomax-CA1 Injectable for the prevention and treatment of New World screwworm (NWS). The 250 mL and 500 mL vial sizes were granted conditional approval last October. Dectomax-CA1 is currently the only nonprescription product conditionally approved by the U.S. Food and Drug Administration (FDA) for NWS treatment. The conditional approval applies to beef cattle, female dairy cattle less than 20 months of age, pregnant beef cows, newborn calves, and bulls. Dectomax-CA1 is not for use in calves to be processed for veal. Dectomax-CA1 is not for use in female dairy cattle 20 months of age or older, except under the conditions of the recently granted Emergency Use Authorization (EUA).
Emergency Use Authorization
The FDA has granted and EUA for use of Dectomax/Dectomax-CA1 in dairy cattle, horses, sheep, pigs, and deer, allowing for the products use in the following situations:
- The prevention and treatment of infestations caused by Cochliomyia hominivorax larvae (myiasis) in dairy cattle (lactating dairy cows with a 468-hour milk withdrawal period, dry dairy cows, and replacement dairy heifers 20 months of age and older), except for calves to be processed for veal.
- The prevention of infestations caused by Cochliomyia hominivorax larvae (myiasis) in deer, swine, and sheep, except for lactating sheep.
- The prevention of infestations caused by Cochliomyia hominivorax larvae (myiasis) in horses at least one year old.
“We continue to work with [the Center for Veterinary Medicine] to find product solutions that may be safe and effective for use in additional species,” said Mike Lormore, director of cattle and pork technical services at Zoetis, in a news release. “The recent conditional approval and emergency use authorization will enable additional producers, veterinarians and animal caretakers to implement prevention and treatment procedures to help protect against NWS.”
