Our Pipeline

We are leaders in Long-Acting Drug Delivery Technology

Our focus is clear. We are working to continue to develop and commercialize pharmaceutical-grade innovative products that set an excellent standard of care in protecting laboratory animal welfare.

Fidelis understands the ethical and scientific importance of providing the highest-quality analgesics to protect the welfare of laboratory animals and limit variability in research results.

Product Development

With one product already successfully commercialized and being used throughout the U.S., we’re committed to leading the industry with quality-driven therapeutics and additional innovations for all animals, small and large, using our proprietary extended-release technology.
Research Capabilities
Fidelis has developed a research platform with proprietary extended-release technology proven to provide up to 72 hours of therapeutic levels (clinical analgesia) with one injection. This technology is triple patent-protected.

Important Safety Information
For Rats, Mice, and Ferrets:
Only administer Ethiqa XR® by subcutaneous injection. Ethiqa XR is not intended for intravenous, intra-arterial, intrathecal, intramuscular, or intra-peritoneal injection. 

Do not use in animals with pre-existing respiratory compromise.

Do not house rats on wood chip-type bedding after administration of Ethiqa XR. Pica involving wood chip type bedding can be lethal.

Ethiqa XR may cause sedation, decreased blood pressure, decreased heart rate,
decreased gastrointestinal mobility, and respiratory depression. Use caution with
concomitant administration of Ethiqa XR with drugs that cause respiratory depression. Animals should be monitored for signs of decreased cardiovascular and respiratory function when receiving Ethiqa XR. 

The safety of Ethiqa XR has not been evaluated in pregnant, lactating, neonatal, or
immune-compromised animals.
For Humans:

Not for use in humans. Keep out of reach of children and pets.

Ethiqa XR contains buprenorphine, a Schedule III controlled substance with an
abuse potential similar to other Schedule III opioids, which may lead to overdose and death.

Ethiqa XR should be handled appropriately to minimize the risk of misuse, abuse,
addiction, and criminal diversion, including restriction of access, the use of accounting procedures, and proper disposal methods as appropriate to the laboratory setting and as required by law.

Ethiqa XR should only be handled and administered by a veterinarian, veterinarian
technician, or laboratory staff trained in the handling of potent opioids. Wear protective clothing when administering Ethiqa XR to avoid direct contact with human skin, eyes, oral, or other mucus membranes which could result in absorption of buprenorphine and adverse reactions.

For more information, consult the Prescribing Information including the Boxed Warning.


Abuse Potential
ETHIQA XR contains buprenorphine, an opioid that exposes humans to risks of misuse, abuse, and addiction, which can lead to overdose and death. Use of buprenorphine may lead to physical dependence. The risk of abuse by humans should be considered when storing, administering, and disposing of ETHIQA XR. Persons at increased risk for opioid abuse include those with a personal or family history of substance abuse (including drugs or alcohol) or mental illness (e.g., depression).

Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression may occur with accidental exposure to or with misuse or abuse of ETHIQA XR. Monitor for respiratory depression if human exposure to buprenorphine occurs. Misuse or abuse of buprenorphine by swallowing, snorting, or injecting poses a significant risk of overdose and death.

Accidental Exposure
Because of the potential for adverse reactions associated with accidental exposure, ETHIQA XR should only be administered by veterinarians, veterinary technicians, or laboratory staff who are trained in the handling of potent opioids. Accidental exposure to ETHIQA XR, especially in children, can result in a fatal overdose of buprenorphine.

Risks From Concurrent Misuse or Abuse with Benzodiazepines or Other CNS Depressants

Concurrent misuse or abuse of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death.
