What is GS-441524? A Guide to Treating FIP in Cats

For years, a diagnosis of FIP (Feline Infectious Peritonitis) in cats was heartbreaking. There was little hope for treatment, and euthanasia often became the only option. But since 2019, thanks to groundbreaking research by Professor Niels Pedersen and his team at UC Davis in California, a promising treatment called GS-441524 has changed the outlook for cats with FIP.

Here's a guide to understanding this treatment, its effectiveness, and what it could mean for cats in the UAE facing an FIP diagnosis.

What is GS-441524?

GS-441524 is an antiviral medication specifically developed to target coronaviruses, including the one responsible for FIP. It acts as a nucleoside analogue, which essentially interferes with the virus's replication process, preventing it from spreading further in the body. This drug is the plasma metabolite of remdesivir, a medication known for treating certain human coronaviruses, making GS-441524 a close relative in antiviral treatments.

GS-441524’s Journey to FIP Treatment

Although GS-441524 was initially created by Gilead Sciences for respiratory conditions in humans, it showed potential for treating cats with FIP. In 2017, Professor Pedersen’s team began clinical trials using this drug on cats suffering from FIP, with promising results.

Early Trials and Key Findings

In Professor Pedersen's first clinical trials:

  • 31 cats with FIP were treated.
  • These cats received 2 mg/kg of GS-441524 daily for 12 weeks.
  • Of these 31 cats, 80% survived and were considered cured, a breakthrough in FIP treatment.

Unfortunately, some cats relapsed and required additional rounds of treatment at a higher dose. The trials concluded that 4 mg/kg per day was the minimum dose for cats with FIP, which provided stronger results and reduced relapse rates.

Recommended Dosages for Different Types of FIP

Dosage recommendations have evolved based on the type of FIP and the cat's symptoms:

  • Abdominal wet FIP: 6 mg/kg per day
  • Pleural or pericardial wet FIP: 8 mg/kg per day
  • Dry FIP: 6-8 mg/kg per day
  • Ocular FIP: 8 mg/kg per day
  • Neurological FIP: 10 mg/kg per day

These doses are starting points, but they may need to be adjusted based on how the cat responds. Cats that show only partial improvement might require a higher dose for effective treatment.

Understanding Treatment and Monitoring

  1. Starting Treatment: GS-441524 treatment typically lasts for 12 weeks. During this period, it’s crucial to monitor the cat’s health closely, looking for any symptoms that indicate a need for dosage adjustment.

  2. Post-Treatment Observation: After completing the initial 12 weeks, an observation period of 12 weeks follows to monitor for any relapses.

  3. Adjustments in Dosage: If the cat does not respond fully, the dosage may be increased. However, lowering the dosage is not recommended as it may lead to a relapse.

Finding FIP Treatment in the UAE

Though GS-441524 has not yet received official licensing in any country, including the UAE, some clinics and networks support treatment for FIP-positive cats. The FIP Warriors® network also provides support, helping pet owners find reputable sources for treatment. You can also check Petsguide.ae, which lists various veterinary clinics and resources across the UAE that might guide you to reliable assistance.

First Aid for FIP

Since FIP is a fast-progressing disease, acting quickly is essential:

  1. Consult Your Vet: Work with a vet familiar with FIP and its management.
  2. Strengthen Immune Health: Ensure the cat has supportive nutrition and hydration.
  3. Follow Dosage Guidelines: Stick to the GS-441524 dosing as recommended and don’t miss doses.
  4. Monitor Symptoms Closely: Any relapse symptoms should prompt an immediate discussion with your vet.
