What is CA1?
CA1 stands for Conditional Approval-1 and denotes the first conditional approval granted by the Food and Drug Administration (FDA) for VETMEDIN® (pimobendan).
VETMEDIN-CA1 is indicated for the delay of onset of clinical signs of heart failure in dogs with B2, preclinical (asymptomatic with a systolic mitral murmur and evidence of increased heart size) myxomatous mitral valve disease (MMVD).1.
What is the difference between conditional approval and full approval?
For both conditional approval and full approval, the drug company must prove, among other things, that the animal drug is safe when used according to the label. Both VETMEDIN and VETMEDIN-CA1 have extensive data demonstrating product safety.1,3 The difference lies in the effectiveness requirement.
Why is VETMEDIN-CA1 being discontinued?
Because VETMEDIN Chewable Tablets and VETMEDIN Solution have now received full approval by the FDA for the Stage B2 preclinical MMVD indication, the VETMEDIN-CA1 conditional approval status is no longer needed from a regulatory standpoint and is being discontinued.
This marks the first time FDA has granted full approval of an animal drug indication that was initially conditionally approved under the agency’s expanded conditional approval authority.
Can I continue to use my existing inventory of VETMEDIN-CA1?
Yes.
The FDA Center for Veterinary Medicine (CVM) has confirmed that remaining inventory of VETMEDIN-CA1 may continue to be distributed, prescribed, and used according to its approved labeling until existing supplies are exhausted.
What presentations of VETMEDIN-CA1 are available?
1.25 mg and 5 mg oblong half-scored chewable tablets, with 50 tablets per bottle.
