Canine Melanoma Vaccine, DNA
The vaccine aids in extending survival times of dogs with stage II or stage Ill oral melanoma and for which local disease control has been achieved (negative local lymph nodes or positive lymph nodes that were surgically removed or irradiated).
• The vaccine is packaged in a box containing four single-dose vials. This package of four vials is sufficient for the initial series of vaccinations required to treat one dog.
• The vaccine is administered in a 0.4 mL dose volume using the VET JET® transdermal vaccination system. Refer to the device package insert for instructions on vaccinating with the device.
• The site of injection for all size dogs is into the muscle of the medial thigh just caudal to the femur.
• Initial treatment requires administration of four doses of vaccine at two week intervals.
• A booster dose should be administered at six month intervals.
vet jet® transdermal vaccination system
For use with ONCEPT® Canine Melanoma Vaccine
The VET JET system consists of two parts - the VET JET device and a nozzle assembly consisting of a vial adapter (for transfer of the vaccine), and a nozzle and plunger. When the VET JET is activated, a spring propels the vaccine at a very high speed out a tiny hole in the tip of the nozzle, through the skin, and into the tissue below. After the injection, the nozzle is removed and discarded. The VET JET is then ready to be prepared for the next injection.
Before you begin, make sure you have each of the following:
LOAD AND FILL THE NOZZLE
The nozzle, plunger, and adapter are pre-assembled into a single unit collectively referred to as the nozzle assembly. If not already assembled, insert the plunger into the nozzle and the nozzle into the luer lock of the adapter.
Place the vaccine vial on a stable surface.
Attach the nozzle assembly to the vaccine vial. Make sure the adapter is firmly pressed onto the vial cap. Push the plunger all the way into the nozzle, forcing air into the vial.
Insert the adapter/nozzle assembly (with vaccine vial attached) firmly into the end of the injector. A soft click may be audible as the nozzle is inserted. However, the nozzle is not yet locked into place at this point.
While pushing down on the nozzle, turn the nozzle clockwise a quarter of a turn until it is locked in place as indicated on the device. The syringe lock button should go down as the syringe is inserted and there will be a distinct audible click after turning the nozzle indicating the nozzle has been seated and is locked in place. The nozzle must be in the locked position before proceeding. Note: When the syringe is locked into place properly it cannot easily be removed without pressing the syringe lock button. If the nozzle does not lock into place easily, do not proceed. Discard the nozzle and try again with a new one.
IMPORTANT NOTE: The nozzle must be firmly locked into place before proceeding. Verify that the nozzle is locked by pulling on the nozzle. There should be virtually no movement of the nozzle in relation to the device.
Gripping the VET JET body in one hand, turn the winding knob clockwise until it stops.
AT THIS POINT THE INJECTOR IS ACTIVATED.
Important Note: Once the injector is activated, do not touch the activator button until you are ready to administer vaccine. Do not attempt to remove the nozzle from the injector once the device is activated without carefully following the instructions for removing the nozzle set forth in Section 11.
Do not point at people or animals.
Verify that the activator button has popped out, exposing the red indicator line.
With injector activated and pointed up (vaccine vial inverted), turn the dose knob counterclockwise to withdraw the vaccine. Vaccine will enter into the nozzle as the dial is turned.
If you see air bubbles in the nozzle, push them back into the vial by turning the winding knob clockwise. Then refill the nozzle again by turning the winding knob counter-clockwise.
Once air bubbles have been removed, set to the desired dose. The dose of ONCEPT Canine Melanoma Vaccine, DNA is 0.4 ml.
Remove the adapter and vial from the nozzle. The nozzle with vaccine will remain attached to the injector.
Be sure to properly dispose of the vaccine vial and unused contents in accordance with label directions and appropriate medical procedures.
Once again verify that the nozzle is locked firmly into place before proceeding with the injection.
GIVING THE INJECTION
Use aseptic technique when administering vaccines. Use appropriate animal restraint techniques standard in veterinary practice for vaccination. The injection site for ONCEPT® Canine Melanoma Vaccine, DNA is over the muscles of the medial thigh caudal to the femur. Firmly hold the injector with nozzle perpendicular to the injection site. Press firmly against the skin and press the activator button. Hold the injector firmly in place until the vaccine has been delivered. (count 1 second)
REMOVING THE NOZZLE
Press the nozzle lock button and turn the nozzle counterclockwise to unlock.
Pull the nozzle off the injector.
Pull out the plunger stem. Discard the nozzle and plunger stem.
After an injection, store the VET JET with the winding knob unwound to reduce pressure on the device spring.
If vaccine will not draw down:
• Remove the nozzle from the vial adapter and connect again.
• Make sure the nozzle is firmly seated in the injector (Step 3).
• Make sure nozzle is firmly connected to the vial adapter.
• If you still experience difficulties, replace nozzle.
If a very loud noise occurs when you press the activator button, you may have dry discharged the Injector - this means there was a large amount of air or no fluid in the nozzle.
• Make sure you have fluid in the nozzle by drawing down dose slowly.
• Change nozzle and vial adapter when appropriate.
If you need to deactivate the injector:
• Make sure the winding knob is turned fully to the clockwise position.
• PRESS AND HOLD the activator button while turning the winding knob counterclockwise at least 1 full turn.
• The injector is now deactivated.
• Not for use in humans.
• Use proper technique for administering injections. Do not position the device nozzle directly over a vessel. Although intravascular injection via jet injection is reported to be extremely unlikely, injecting over a vessel may produce an adverse effect or render the injection ineffective. Adverse reactions may occur which include, but are not limited to, perforation, bruising, swelling, or tenderness.
• When administering the vaccine, hold the device at a 90° angle to the site. Push the tip of the nozzle firmly into the injection site and stabilize the injection site with the “free” hand to prevent movement until all vaccine has been delivered. Failure to do this could result in a small laceration/bruise at the site of the injection.
• When the filled nozzle is locked in the device, the medication will be expelled from the device when the activator button is pressed. If the device’s activator button is accidentally pressed, the fluid stream is capable of penetrating soft tissue even from a distance of a few centimeters. Do not point the injector toward people or animals.
• Do not place any object or fingers inside the nozzle end of the device.
• Do not attempt to administer an injection without being certain that the nozzle is properly locked into place. Attempts to inject without locking the nozzle may result in forcible ejection of the nozzle and risk of injury to patient or operator. Please see full instructions.
• Always be certain that the nozzle is filled with liquid before discharging the injector.
• DO NOT DISCHARGE THE INJECTOR WITHOUT FLUID IN THE NOZZLE. This may result in damage to the injector or breakage of nozzle assembly.
• Use the injector as specified. Do not eject vaccine into the air or onto an animal’s haircoat. Administer vaccines at the appropriate site specified for the product.
• Only use this injector to administer vaccines that are formulated for administration with the VET JET. Failure of proper administration can result in failure to protect the patient against the target disease(s).
• When the injector is activated, use caution to avoid pressing the activator button until you are ready to administer the vaccine.
• Do not attempt to remove the nozzle from an activated injector. See deactivation instructions (Helpful Hints).
• Do not immerse the injector in water or other solutions.
• If you suspect any malfunction, please call Merial Technical Services at 1-888-Merial1, option 3 for assistance.

• A transient, low-grade fever may be observed in some dogs.
• Transdermal injection has been associated with injection site pain, swelling, and bruising. Please see device label for complete information.
Mode Of Action
• Each dose contains plasmid DNA that expresses the gene coding for human tyrosinase.
• Tyrosinase protein is over expressed on melanoma cells.
• Upon injection, the DNA is taken up by muscle cells which then express the human tyrosinase protein.
• The human tyrosinase protein is different enough from the canine tyrosinase protein that it will stimulate an immune response, yet similar enough to the canine tyrosinase that the immune response is effective against canine melanoma cells which express tyrosinase.
Precautions And Contraindications
• There are no known contraindications for the use of this product in dogs with oral melanoma.
• Store at 2-7°C (35-45°F). Do not freeze. Use entire contents when first opened.
• In rare instances, administration of vaccines may cause lethargy, fever, and inflammatory or hypersensitivity types of reactions. Treatment may include antihistamines, anti-inflammatories, and/or epinephrine.
