Gilvetmab:
Product Grant Program Annoucement

As a key pillar of oncology therapeutics, the field of immunotherapy has brought drastic and inspiring changes to the landscape of cancer care.
Chief among the immunotherapeutic modalities is that of checkpoint inhibition. We at Merck Animal Health eagerly anticipate the positive impact of checkpoint inhibitors like gilvetmab on our veterinary patients but appreciate that numerous questions remain in veterinary medicine about the optimal clinical scenarios for use of checkpoint inhibitors. That is why we are pleased to support our Gilvetmab Product Grant Program, offering independent researchers a supply of gilvetmab to focus some of your research efforts on checkpoint inhibition. A summary of the grant program details may be found below.
We appreciate everything you do day in and day out for the benefit of your patients. Thank you for allowing us to help you advance the field of veterinary oncology.

Cycle 3
September 25th , 2025 – January 31st, 2026
Decision announcement
March 2nd, 2026
Product Grant Only
Provides gilvetmab product at no cost; does not provide monetary funding for research activities.
24-Month Project Timeline
All research must be completed within two years from enrollment of first patient.
Funding Requirement
Recipients must secure and demonstrate adequate funding for their study within 6 months of award notification.
Patient Enrollment Deadline
Must begin enrolling patients within 3 months of obtaining funding.
Final Data Presentation
Complete data must be presented to Merck Animal Health at grant completion (publication encouraged but at recipient’s discretion).
Review Process:
Applications are reviewed by an external committee of veterinary oncology experts (medical, surgical, and radiation oncologists) with no Merck Animal Health affiliation or conflicts of interest. Final selection is made by a Merck Animal Health committee with clinical veterinary medicine and research expertise.
Selection Criteria:
- Clinical Relevance – Priority given to proof-of-principle and proof-of-concept studies with readily measurable outcomes that address practical questions in veterinary oncology
- Feasibility – Clear strategy for expedient case accrual, appropriate study design, and ability to complete within 24 months
- Investigator Qualifications – Adequate facilities, research experience, and required approvals (IACUC, etc.)
- Strong Evidence Base – Robust background research grounded in immune checkpoint inhibitor literature
- Secured Funding – Priority to projects with identified funding sources to support research activities
Award recipients must complete Progress Reports every 6 months and present the complete data to Merck Animal Health at the completion of the grant period. Though strongly encouraged, the decision to publish the data is at the discretion of the Award Recipient.
Please see the Gilvetmab Grant Program Details for more information.
Merck Animal Health reserves the right in its sole discretion to modify or terminate the program at any time
Program Eligibility
Projects must be conducted in the United States of America, excluding its territories and possessions.
Eligibility:
Open to veterinary oncologists boarded by the ACVIM or ECVIM, and other board-certified veterinary specialists with demonstrable experience in canine cancer treatment, including:
Board-Certified Veterinary Medical Oncologists
Board-Certified Veterinary Radiation Oncologists
Board-Certified Veterinary Surgical Oncologists
Board-Certified Veterinary Internal Medicine Specialists (with acceptable evidence of canine cancer experience)
Board-Certified Veterinary Dermatologists (with acceptable evidence of canine cancer experience)
Eligible organizations include academic institutions, nonprofits, and for-profit entities.
Private specialty practices and academic institutions are strongly encouraged to consider collaboration for ease of case accrual.
Study Guidelines:
Granted product should be used in a clinical application seeking to better understand the role of checkpoint inhibitors in different clinical scenarios including but not limited to: evaluation of different doses or with different dosing schemes; with, prior to, or after adjunct therapeutics; or in the scenario of evaluation of biomarkers. All information must be collected and evaluated by the Investigator. Merck Animal Health maintains the responsibility to ensure that the Investigator who receives a grant for any extra-label use (ELU) will use the product in accordance with the appropriate oversight and record keeping (ie, require owner consent, provide for reporting of adverse events).
Ethical Conduct:
Where applicable, evidence of approval by an institutional animal care and use committee (IACUC) will be required. For those institutions without a formal IACUC, we require evidence of completion of a course on Good Clinical Practice (GCP) for Veterinary Clinical Trials, and a signed statement of ethical treatment of animals.

Important Information
When considering a research proposal that would include gilvetmab (Canine PD-1 Monoclonal Antibody Cancer Immunotherapeutic) you should be aware of the most common side effects. During clinical studies in dogs with MCT, the most common (> 10% of gilvetmab treated dogs) adverse events (described and graded following the VCOG consensus document on common terminology for adverse reactions following chemotherapy or biologic antineoplastic therapy in dogs and cats) included: lethargy/fatigue/general performance, reduced appetite, elevated ALP and ALT, diarrhea, and vomiting. In dogs with melanoma, the most common adverse events were lethargy/fatigue/general performance, reduced appetite, vomiting, and weight loss. In addition, less commonly, infusion associated reactions were seen. These reactions included edema of the face and limbs, mild injection site swelling or discoloration, pallor, increased respiratory rate, anaphylaxis, and hypotension. Treatment of signs of anaphylaxis may be indicated, depending on the nature and severity of the reaction. For severe or life-threatening infusion-related reactions, stop infusion and permanently discontinue treatment.
The phenomenon of pseudoprogression, which is an increase in the size of the primary tumor, or the appearance of a new lesion followed by tumor regression, is well documented in people treated with immune checkpoint inhibitors. Two dogs in the melanoma treatment group displayed growth patterns that could be considered consistent with pseudoprogression. It is important to consider this phenomenon in dogs that experience increase in tumor size to prevent discontinuation of therapy when not indicated. It is believed that the best way to discern between pseudoprogression and tumor growth would be obtaining a biopsy.
There are no special handling requirements for gilvetmab, though it does require intravenous infusion over at least 30 minutes and pretreatment with diphenhydramine.
Adverse Event Reporting
It will be the responsibility of the Award Recipients, or other veterinary staff involved, to report adverse events to Merck Animal Health at 1-800-224-5318 or via the Adverse Event Reporting Form provided to Award Recipients.
Adverse event reporting
