Newly released documents uncovered by a watchdog group show that the
University of Florida suspended a research study after the death of two
animals.
The group is now asking for the university and its president to terminate
the program entirely.
The temporary halt comes after university officials found that a study's
principal investigator failed to follow through on "corrective actions"
required by UF's Institutional Animal Care and Use Committee (IACUC) during
research that resulted in the death of two dogs, documents obtained by Stop
Animal Exploitation Now! (SAEN) show.
The dogs were part of a Duchenne muscular dystrophy study in mid-2023, and
each received an adeno-associated virus vector — a form of gene therapy —
administrated directly into the heart.
David Norton, UF's vice president for research, notified Axel Wolff,
director of the Division of Compliance Oversight for the Office of
Laboratory Animal Welfare — part of the National Institutes of Health — of
the suspension in a letter dated Oct. 19, 2022.
“Due to the lack of principal investigator response to the above corrective
actions and concerns over animal welfare and overall protocol adherence, the
IACUC voted to suspend the protocol involved in the adverse event effective
immediately,"
Among the corrective actions required were that the lab and veterinarians
with UF's Animal Care Services division develop a standard operating
procedure for UF's Small Animal Hospital so that the dogs receive better
care. The committee also has required modification to the IACUC protocol to
better outline human endpoints.
Officials for SAEN said the suspension doesn't go far enough at that the
study should be permanently shut down.
“Given the fact that this project has already had violations of federal
regulations sufficient to cause death of two research subjects, and that the
behavior of the Principal Investigator has given rise to 'concerns over
animal welfare and overall protocol adherence,' and that this is
experimentation is in an area wherein significant toxicity to humans has
already been demonstrated, this protocol should be permanently terminated,”
wrote SAEN's co-founder Michael A. Budkie in a letter to the UF President
Ben Sasse.
The suspension follows a report written by Norton to the Office of
Laboratory Animal Welfare that outlined events that ultimately led to the
dogs' deaths. It noted that “the procedure went smoothly and the dogs
recovered well.”
On Aug. 20, however, one of the dogs began to show "abnormal respiratory
signs" after receiving an injection a day earlier. According to UF's report,
the dog was taken to UF's Small Animal Hospital where its condition "rapidly
deteriorated" and it ultimately stopped breathing.
On Sept. 3, another dog involved in the June 24 study suffered an "episode
of regurgitation." Over the following days, the dog developed intermitted
inappetence, fever and abnormal palpitation. The dog was admitted to the
Small Animal Hospital on Sept. 7 for imaging and supportive care. A hiatal
hernia and evidence of pneumonia were discovered during testing. After
receiving treatment, the dog's appetite and fever returned to normal and it
was discharged on Sept. 12.
But just three days later, the dog's fever returned, and suffered from
"respiratory distress." The dog was taken back to the hospital where a
decision was made on Sept. 18 to euthanize the animal.
The university's Institutional Animal Care and Use Committee (IACUC) voted
on Oct. 4 to classify the causes of death as adverse events to the
treatment.
A complaint by SAEN in February alleges that the dog died on Aug. 20 due to
not being treated timely, and that the animal was not adequately observed.
The complaint insists on a full investigation of UF's muscular dystrophy
research and, upon its conclusion, UF be issued the maximum allowable fine
of $12,722 per infraction per animal.
In an emailed response to The Sun regarding the complaint in February, a UF
spokesman said it "is committed to the ethical use of animals in its pursuit
of medical advances that benefit both humans and animals"
"Almost every drug, treatment, medical device, diagnostic tool or cure we
have today was developed with the help of laboratory animals," the statement
continued. "Animal research at UF is governed by a federally mandated
Institutional Animal Care and Use Committee that reviews all requests for
approval to use vertebrate animals and inspects all areas where animals are
housed and used."
University officials say that its Animal Care and Use Program has received
full and continued accreditation from AAALAC International, a nonprofit that
promotes the humane treatment of animals in science.
"Full accreditation serves as a testament to our program’s commitment to
quality and humane animal care, rigorous research practices, and continuous
improvement," UF's statement said.
