Clinical Trial Summary

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.

• 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

• Anemia due to unexplained or known gastrointestinal bleeding

• Renal impairment or a risk for renal failure due to volume depletion.

• History of asthma or any other chronic pulmonary disorder, with the exception of childhood asthma and asymptomatic asthma, which were assessed individually by the Principal Investigator

• Current tobacco use or a past history of smoking > or = 5 pack-years within the last 5 years

• A history of any other clinically significant, unstable medical problem, which in the opinion of the Investigator would have interfered with study participation

• Participation in another investigational drug study within 30 days of study entry, or 5 times the half-life of the investigational drug, whichever was longer

• Positive test for Helicobacter pylori (H. pylori) at screening
