About

This was an open label, three way study in participants with symptomatic allergic rhinitis. The following 3 treatments were administered to each subject during dosing periods 1, 2 and 3, respectively:

Treatment A: Single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) on Day 1 of Period 1.
Treatment B: Single intranasal dose of oxymetazoline hydrochloride followed by a single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) 30 minutes later on Day 1 of Period 2.
Treatment C: Seven days of treatment with intranasal fluticasone propionate (between Periods 2 and 3) followed by a single intranasal dose of 30 mg ketorolac tromethamine (one 15 mg spray into each nostril) on Day 1 of Period 3.

Subjects remained resident in the Clinical Unit from Day 1 until the morning of Day 2 in each period and there was a washout period of 2 to 7 days between periods. A post study medical was performed within 7 days of Period 3.

The objectives of this study were:

To assess the pharmacokinetics (PK) of intranasal ketorolac in participants with symptomatic allergic rhinitis.
To assess the effects of a single dose of intranasal oxymetazoline hydrochloride on the pharmacokinetics and tolerability of intranasal ketorolac in participants with symptomatic allergic rhinitis.
To assess the effects of chronic administration of fluticasone propionate on the bioavailability and tolerability of intranasal ketorolac in participants with symptomatic allergic rhinitis.

Inclusion criteria

Male or female volunteers, aged between 18 and 65 years inclusive
Participant had a history of allergic rhinitis for which treatment had been required at least 3 days out of 7 within the last 3 months. Subjects who were symptomatic of allergic rhinitis but were not currently using therapy because they had found it ineffective may have been included
Participant was otherwise considered to exhibit general good health, in the opinion of the Investigator
Participants may have had known medical conditions that were considered "stable" and not expected to interfere with the study outcome or to be adversely affected by their involvement in the study. This was determined by the Investigator at the time of screening by the following:
- A pre-study physical examination with no clinically significant abnormalities
- Vital signs within normal ranges or outside the normal range but not deemed clinically significant in the opinion of the Investigator
- An electrocardiogram (ECG) with no clinically significant abnormalities
- Full medical history
Participant had bilateral patent nasal airways at screening as assessed by the Investigator
Participant had a body mass index (BMI) between 19 and 29 kg/m2
Female participants of child bearing potential:
- Must have had a negative urine pregnancy test prior to entry into the study
- Must not have been breast feeding
All female participants of child bearing potential and all male participants with female partners of child bearing potential must have consented to use a medically acceptable method of contraception (oral or implanted contraceptive hormones with combined use of barrier contraception, condom or diaphragm with spermicidal agent, intrauterine device, menopausal [defined as last menstrual period >12 months ago] or surgical sterilization) throughout the study period and for a minimum of 4 weeks or 1 full menstrual cycle prior to inclusion
Participant must have been able to provide written informed consent
Participant's pre-study clinical laboratory findings were within normal range or if outside of the normal range not deemed clinically significant in the opinion of the Investigator
Glomerular filtration rate >75 mL/minute as calculated using the Cockroft-Gault calculation for creatinine clearance

Exclusion criteria

Any known allergy or sensitivity to ketorolac tromethamine, oxymetazoline hydrochloride, fluticasone propionate or formulation ingredients
Any history of co-existing nasal polyps, NSAID sensitivity and asthma
Daily use of an intranasal decongestant medication
Allergic reaction to aspirin or other NSAIDs
Current upper respiratory tract infection or other respiratory tract condition that could have interfered with the absorption of the nasal spray or with the assessment of AEs
Use of any non-prescribed drug in the 72 hours prior to study drug administration and during the study. Paracetamol use was not allowed within the 24 hours prior to Day 1 of each period. NSAIDs were restricted for at least 3 days or 5 half-lives, whichever was longer, prior to dosing on Day 1 of Period 1, and must not have been used throughout the study. Current prescribed medications were not discontinued prior to entry into the study or during study participation, unless known to interact with ketorolac as per the product information (injectable)
Any suspicion of rhinitis medicamentosa (chronic daily use of topical decongestants)
Use of a monoamine oxidase inhibitor in the 14 days prior to study entry
Positive serum test for human immunodeficiency virus (HIV) or hepatitis B or C at screening
Positive serum alcohol test at screening or on entry into the study
Positive urine drug screen for any non-prescribed drugs of abuse (DOA) at screening or on entry into the study
Clinically significant abnormality on screening laboratory tests
History of cocaine use
Concurrent use of ritonavir or other potent CYP3A4 inducers or inhibitors.
Blood donation within 30 days of beginning study participation
Active peptic ulcer disease, gastrointestinal bleeding or perforation, or a history of peptic ulcer disease or gastrointestinal bleeding
