Keep CREDELIO CAT in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.


Precautions:



Lotilaner is a member of the isoxazoline class. This class has been associated with neurologic adverse reactions including tremors, ataxia, and seizures. Neurologic adverse reactions have been reported in cats receiving isoxazoline class drugs, even in cats without a history of neurologic disorders. Use with caution in cats with a history of neurologic disorders.

The safety of CREDELIO CAT has not been established in breeding, pregnant and lactating cats (see Foreign Market Experience).

The effectiveness of CREDELIO CAT against Ixodes scapularis in kittens less than 6 months of age has not been evaluated.


Adverse Reactions:



In a well-controlled U.S. field study, which included 341 cats (228 cats treated with CREDELIO CAT and 113 cats treated with a topical active control), there were no serious adverse reactions.

Contact Information



To report suspected adverse events, for technical assistance or to obtain a copy of the Safety Data Sheet (SDS), contact Elanco US Inc. at 1-888-545-5973.

For additional information about adverse drug experience reporting for animal drugs, contact FDA at 1-888-FDA-VETS or http://www.fda.gov/reportanimalae.


Clinical Pharmacology:



Following oral administration of 26 mg/kg (the maximum labeled dose), peak lotilaner concentrations were achieved in most cats at the 24-hour sampling point. Cats 3 months of age had a shorter elimination half-life (average of 7.5 days) than at 7 months of age (average of 32 days).

Due to reduced drug bioavailability in the fasted state, CREDELIO CAT must be administered with a meal or within 30 minutes after feeding.


Mode Of Action:



Lotilaner is an ectoparasiticide belonging to the isoxazoline group. Lotilaner inhibits insect and acarine gamma-aminobutyric acid (GABA)-gated chloride channels. This inhibition blocks the transfer of chloride ions across cell membranes, which results in uncontrolled neuromuscular activity leading to death of insects and acarines. The selective toxicity of lotilaner between insects and acarines and mammals may be inferred by the differential sensitivity of the insects and acarines’ GABA receptors versus mammalian GABA receptors.


Effectiveness:



In a well-controlled laboratory study, CREDELIO CAT began to kill fleas six hours after administration, with greater than 98% of fleas killed within 12 hours after administration. In another well-controlled laboratory study, CREDELIO CAT demonstrated 100% effectiveness against adult fleas 24 hours after administration or infestation for 35 days.

In a 90-day well-controlled U.S. field study conducted in cats with existing flea infestations of varying severity, the effectiveness of CREDELIO CAT against fleas on Days 30, 60 and 90 compared to baseline was 98.5%,100% and 100%, respectively. Cats with signs of flea allergy dermatitis showed improvement in erythema, papules, scaling, alopecia, dermatitis/pyodermatitis, and pruritus as a direct result of eliminating fleas.

In a well-controlled laboratory study, CREDELIO CAT killed fleas before they could lay eggs, thus preventing subsequent flea infestations after the start of treatment of existing flea infestations for 30 days.

In well-controlled laboratory studies, CREDELIO CAT demonstrated >97% effectiveness against Ixodes scapularis ticks 72 hours after administration or infestation for 31 days.

Palatability: In the U.S. field study, which included 648 doses administered to 225 cats, 21.1% of the doses were voluntarily consumed when CREDELIO CAT was offered by hand, on the floor, or in an empty bowl, an additional 25.8% of doses were voluntarily consumed when CREDELIO CAT was offered with food, and 52.6% of doses required placement of the chewable tablet in the back of the cat’s mouth.

Owners were unable to administer CREDELIO CAT for 0.5% of doses.


Animal Safety:



In a margin of safety study, CREDELIO CAT was administered orally to 24 (8 cats/group) 8-week-old cats at 1, 3 and 5X the maximum labeled dose of 26 mg/kg every 28 days for eight consecutive doses. The 8 cats in the control group (0X) were untreated.

There were no clinically-relevant, treatment-related effects on physical and neurologic examinations or gross pathology. Dry food consumption was reduced in male cats in all treated groups compared to control cats. Body weights of male cats in the 3X group were less than the control male cats. Vomiting occurred post-dosing in cats in all groups, including the control group, but was increased in the 5X group. At multiple time points, neutrophil counts were decreased (750-2710/μL; low end of normal: approximately 2800/μL) in cats in all treated groups compared to control cats, including in a cat in the 3X group that died during anesthesia to obtain the electrocardiogram (ECG). From Days 28 to 92, two and three female cats in the 3X and 5X group, respectively, had elevations in blood urea nitrogen (BUN) at least at one time point (37-43 mg/dL; high end of normal: 36 mg/dL). Three cats each in the control, 1X and 5X groups and six cats in the 3X group had minimal, usually unilateral, tubular regeneration of the kidneys. One cat each in the control, 1X and 5X groups and four cats in the 3X group had minimal generalized lymphoid depletion of the thymus. Four of the five cats in the two high-dose groups (3X and 5X) with the thymus changes also had neutropenia at 25% or more of the time points.

Blood concentrations of lotilaner confirmed systemic exposure in all cats administered lotilaner, although the exposure was less than dose proportional.


Storage Information:



Store at 15-25°C (59 -77°F), excursions permitted between 5 to 40°C (41 to 104°F).


How Supplied:



CREDELIO CAT is available in two chewable tablet sizes for use in cats: 12 and 48 mg lotilaner. Each chewable tablet size is available in color-coded packages containing 1 chewable tablet. The 48 mg chewable tablet size is also available in color-coded packages containing 3 or 6 chewable tablets.

        Risk-Benefit Consideration for Cats on Other Isoxazolines:

        If a cat is currently receiving another isoxazoline product for routine ectoparasite control, veterinarians should consider administering CREDELIO CAT to cats diagnosed with NWS myiasis based on a risk-benefit assessment and the emergency nature of NWS myiasis treatment.

        Information Supporting Emergency Use Authorization

        Based on the scientific evidence available to FDA, including data from published scientific literature, it is reasonable to believe that CREDELIO CAT may be effective for the treatment of infestations caused by NWS (Cochliomyia hominivorax) larvae (myiasis) in cats and kittens, and the known and potential benefits of CREDELIO CAT outweigh the known and potential risks.

        A study conducted by Han and Yasmin

        Han, HS, Yasmin, L (2020). Chrysomya bezziana (Diptera: Calliphoridae) infestation in two Malaysian cats treated with oral lotilaner. Vet Dermatol, 31:335-e87.

        evaluated the effectiveness of lotilaner

        Same formulation as CREDELIO CAT.

        for the treatment of naturally acquired Old World screwworm (OWS, Chrysomya bezziana) myiasis in cats in Malaysia. Two client-owned cats with active myiasis caused by Chrysomya bezziana larvae were enrolled. The cats included a 3-year-old male intact cat with a wound on the left hind paw and a 9-year-old male neutered cat with a wound on the right cervical neck region. Both cats received a single oral administration of lotilaner at doses of either 6 or 26 mg/kg body weight, following the dose bands for the approved flea and tick indications. The study was a case report and did not include a control group.

        After treatment, both cats were hospitalized for 10 and 11 days and wounds were cleansed and flushed with saline solution until re-epithelization occurred. The study demonstrated 100% larvicidal effectiveness against OWS (Chrysomya bezziana) at 24 hours post-treatment in both cats. There were no adverse reactions during the study.

        A study conducted by do Vale et al.

        do Vale TL, Costa AR, Miranda LM, Silva GF, Silva NCS, Lima TB, Chaves DP, Sager H, Lasmar PVF, Costa-Junior LM. Efficacy of lotilaner against myiasis caused by Cochliomyia hominivorax (Diptera: Calliphoridae) in naturally infested dogs. Parasit Vectors. 2023;16(1):86.

        evaluated the effectiveness of CREDELIO (lotilaner) for the treatment of naturally acquired NWS myiasis in dogs in Brazil. Eleven client-owned dogs with active myiasis caused by Cochliomyia hominivorax larvae were enrolled based on lesion severity and larval burden. All dogs received a single oral administration of CREDELIO using the dose bands for the approved flea and tick indications. The study did not include a control group. After treatment, the dogs were kept in individual kennels with a removable tray. The dogs were observed 2- and 6-hours post-treatment, at which times expelled larvae were collected and quantified. At 24 hours post-treatment, the remaining larvae were mechanically removed from the wound and counted. The study demonstrated 100% overall effectiveness (number of expelled live and dead larvae and dead larvae mechanically removed) against Cochliomyia hominivorax larvae at 24 hours post-treatment with expulsion of larvae of 80.5% and 93% at 2 and 6 hours after treatment, respectively. The mean larvicidal effectiveness was 41.1% at 24 hours. There were no adverse reactions during the study.

        There are several limitations of the data supporting the benefits of CREDELIO CAT for the treatment of NWS infestations, as the available study in cats was conducted against a different parasite species (OWS). The Han and Yasmin study was conducted in a limited population of two cats naturally infested with Old World screwworm (Chrysomya bezziana) in Malaysia, and the inferential value to the United States population and NWS species is unknown. Additionally, the case report design, lack of a control group, and demonstrated effectiveness in a different parasite species (Chrysomya bezziana vs. Cochliomyia hominivorax) limits the ability to define a pure treatment effect. The do Vale et al. study was conducted in a limited population of eleven naturally infested dogs in Brazil, and the inferential value to cats is unknown; however, the study used the approved lotilaner dose for the flea and tick indications. In that study, the primary mechanism of action against Cochliomyia hominivorax appears to be live larval expulsion. Additionally, the use of mechanical removal coupled with the lack of a control group confound the ability to define a pure treatment effect.

        The available clinical data supporting the effectiveness of CREDELIO CAT against OWS (Chrysomya bezziana) larvae, and the effectiveness data for lotilaner in dogs against NWS, along with the established safety profile, support the potential benefit of CREDELIO CAT in the authorized patient population for the treatment of infestations caused by NWS larvae.

        Contraindications:

        There are no known contraindications for the use of CREDELIO CAT.

        Warnings:

        Not for human use. Keep this and all drugs out of the reach of children. Keep CREDELIO CAT in a secure location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose.

        Precautions:

        Lotilaner is a member of the isoxazoline class. This class has been associated with neurologic adverse reactions including tremors, ataxia, and seizures. Neurologic adverse reactions have been reported in cats receiving isoxazoline class drugs, even in cats without a history of neurologic disorders. Use with caution in cats with a history of neurologic disorders.

        The safe use of CREDELIO CAT in breeding, pregnant, or lactating cats has not been evaluated (see Foreign Market Experience on package insert).

        The safety of CREDELIO CAT has not been evaluated in cats less than 8 weeks of age or less than 2.0 lbs.

        Adverse Reactions:

        Refer to the package insert for full prescribing information, including Animal Safety, Adverse Reactions, and Post-Approval Experience.

        As described in the Letter of Authorization, veterinary facilities and veterinarians must report all SERIOUS ADVERSE EVENTS* potentially related to CREDELIO CAT use under this EUA (1) by contacting Elanco US Inc. at 1-888-545-5973, (2) by downloading and submitting Form FDA 1932a available at https://www.fda.gov/reportanimalae, or (3) contacting FDA at 1-888-FDA-VETS to request this form.

            Additional Information for Client (e.g., Animal Owner):

            The lifecycle for C. hominivorax is as short as 21 days and wounds can be rapidly infested. Proper wound care and management practices are essential for preventing NWS myiasis. Cats may become reinfested following treatment.

            Clients should be advised that:

            • Gloves should be worn if cleaning the wound or the cat’s bedding or disposing of larvae.
            • Cats should be housed to prevent exposure to NWS flies until wounds have fully healed.
            • Live larvae may exit the wound and be deposited on bedding or areas where the cat sits or lies after treatment.
            • If expelled larvae are seen, clients should place the larvae in a sealed container with rubbing alcohol.
            • If there is worsening of the wound, the client should contact the veterinarian.
            • How Supplied:
