Triamcinolone Acetonide in the Treatment of Perennial Allergic Rhinitis: A post hoc Analysis of Quality of Life during a Phase III Study.

ABSTRACT:

Introduction

Allergic rhinitis (AR) is a disease that affects ≤24% of people in Russia, significantly impairing quality of life (QoL). Intranasal corticosteroids, such as triamcinolone acetonide (TAA), are considered effective drugs for treatment. A post hoc analysis of data (phase III NASANIF trial) examined weekly QoL changes in patients receiving TAA for the treatment of perennial AR (PAR).

Methods

NASANIF (NCT03317015) was a double-blind, parallel group, multicenter, prospective, noninferiority, phase III clinical trial. Patients with PAR were randomized (1:1) to receive TAA or fluticasone propionate (FP) for 4 weeks. Here, a post hoc analysis measures QoL using a shortened Rhinoconjunctivitis Quality of Life Questionnaire (miniRQLQ). Differences in miniRQLQ score were evaluated using a mixed linear model and descriptive statistics. A subgroup analysis was performed in patients with a previous diagnosis of allergic conjunctivitis.

Results

Of 260 patients eligible for randomization, 128 each completed treatment with TAA or FP. Overall and individual domain scores progressively improved and were significantly different versus baseline at week 4 in both treatment groups: LS mean difference TAA: -30.92 (95% CI [-33.01 to -28.83]), p < 0.001, and FP: -31.13 (-33.23 to -29.04), p < 0.001. In both arms of the subgroup, there was a significant reduction in eye symptoms. There was no significant difference between the TAA and FP treatment groups in any analyses.

Conclusions

TAA is effective in improving overall and individual domains of QoL in patients with PAR, over 4 weeks. Patients with a previous diagnosis of allergic conjunctivitis experienced significant improvements in QoL related to the resolution of these symptoms.

Project description:IntroductionOsteoarthritis (OA) is common and its prevalence is increased in military service members. In a phase 3 randomized controlled trial (NCT02357459), a single intra-articular injection of an extended-release formulation of triamcinolone acetonide (TA-ER) in participants with unilateral or bilateral knee OA demonstrated substantial improvement in pain and symptoms. Bilateral knee pain has emerged as a confounding factor in clinical trials when evaluating the effect of a single intra-articular injection. Furthermore, unilateral disease is frequently first to emerge in active military personnel secondary to prior traumatic joint injury. In this post hoc analysis, we assessed efficacy and safety of TA-ER in a subgroup of participants with unilateral knee OA.MethodsParticipants ≥ 40 years of age with symptomatic knee OA were randomized to a single intra-articular injection of TA-ER 32 mg, TA crystalline suspension (TAcs) 40 mg, or saline-placebo. Average daily pain (ADP)-intensity and rescue medication use were collected at each of weeks 1-24 postinjection; Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)-A (pain), WOMAC-B (stiffness), WOMAC-C (function), and Knee Injury and Osteoarthritis Outcome Score Quality of Life (KOOS-QoL) were collected at weeks 4, 8, 12, 16, 20, and 24 postinjection. Adverse events (AEs) were assessed throughout the study. Participants with unilateral knee OA were selected for this analysis.ResultsOf 170 participants with unilateral OA (TA-ER, N = 51; saline-placebo, N = 60; TAcs, N = 59), 42% were male and 89% were white. TA-ER significantly (p < 0.05) improved ADP-intensity vs. saline-placebo (weeks 1-24) and TAcs (weeks 4-21). TA-ER significantly (p < 0.05) improved WOMAC-A vs. saline-placebo (all time points) and TAcs (weeks 4, 8, 12, 24). Consistent outcomes were observed for rescue medication, WOMAC-B, WOMAC-C, and KOOS-QoL. AEs were similar in frequency/type across treatments.ConclusionTA-ER provided 5-6 months' pain relief that consistently exceeded saline-placebo and TAcs, suggesting that TA-ER injected intra-articularly into the affected knee may be an effective non-opioid treatment option. Although the participants included in this analysis did not fully represent the diverse demographics of active service members, the substantial unmet medical need in the military population suggests that TA-ER may be an important treatment option; additional studies of TA-ER in active military patients are needed.Trial registrationClinicalTrials.gov NCT02357459.FundingFlexion Therapeutics, Inc.

Project description:BackgroundIntra-articular corticosteroids are commonly used for pain relief in patients with knee osteoarthritis. Simultaneous intra-articular corticosteroid (CS) knee injections may be beneficial for the ~80-90% of patients who present with, or develop, bilateral knee osteoarthritis, but concurrent injections may increase systemic CS exposure and data on safety/tolerability are lacking. Triamcinolone acetonide extended release (TA-ER) has shown decreased systemic triamcinolone acetonide exposure compared with traditional triamcinolone acetonide crystalline suspension (TAcs) after a single knee injection in patients with knee osteoarthritis. This phase IIa study was designed to assess the safety and systemic triamcinolone acetonide exposure following injections of TA-ER or TAcs into each knee of patients with bilateral knee osteoarthritis.MethodsPatients (⩾40 years) meeting American College of Rheumatology criteria for knee osteoarthritis in both knees received concurrent single intra-articular injections of TA-ER 32 mg or TAcs 40 mg into each knee (total: 64 mg and 80 mg, respectively) and were followed for 6 weeks. Safety was evaluated based on treatment-emergent adverse events (TEAEs). Blood samples for pharmacokinetic analysis were collected pre-injection, and at the following postinjection time points: 1, 2, 3, 4, 5, 6, 8, 10, 12, and 24 h, and days 8, 15, 29, and 43.ResultsBaseline characteristics were balanced between patients randomly assigned to TA-ER (n = 12) or TAcs (n = 12). Both treatments were well tolerated with comparable TEAE profiles. Peak plasma triamcinolone acetonide concentrations (Cmax) were lower following bilateral TA-ER injections [geometric mean, 2277.7 pg/ml (95% CI, 1602.13-3238.04)] compared with bilateral TAcs injections [7394.7 pg/ml (2201.06-24,843.43)], with median times to Cmax (Tmax) of 4.5 and 6.5 h, respectively.ConclusionsIn patients with bilateral knee osteoarthritis, intra-articular injection of TA-ER into both knees was well tolerated. Consistent with pharmacokinetic profiles observed after a single knee injection, plasma triamcinolone acetonide concentrations were lower after bilateral TA-ER injections compared with the higher and more variable concentrations observed after bilateral TAcs injections.Clinicaltrialsgov identifierNCT03378076.

Project description:Background:Allergic respiratory diseases such as allergic rhinitis (AR) and allergic asthma (AA) are common conditions that can influence sleep and daytime functioning. However, the significance of this impact is unclear-particularly in perennial allergy sufferers. This study investigates the impact of perennial allergy on sleep, daily activities and productivity. Methods:Adults with self-reported or physician-diagnosed perennial AR aged ≥ 18 years were recruited in Denmark, France, Germany and Sweden. Allergy sufferers were identified using online panels closely matching national population characteristics for each country. Impact on sleep, work, productivity and activity (by the Work, Productivity and Activity Index) were analysed. Descriptive analyses were conducted. Results:In total, 511 subjects with perennial AR (47.4% also with seasonal allergy) completed the survey. Most subjects (77.5%) had a physician-diagnosis of AR; 46.4% were diagnosed with both AA and AR. Most subjects (65.2%) reported sensitisation to house dust mites. Of all subjects, 66.0% reported sleep problems. Subjects with sleep problems woke, on average, 3.8 times per night, with 92.0% taking 15+ min to fall asleep (22.2% took 60+ min). Upon waking at night, 40.8% struggled to get back to sleep, and 69.2% had difficulties waking in the morning due to tiredness. Disturbances in daily functioning due to sleep issues were reported in 85.5-95.0% of subjects with sleep problems across all aspects investigated. Overall work and activity impairment were 53.3% and 47.1%, respectively. Sleep issues were more frequent (78.1% vs 54.7%) in those diagnosed with both AR and AA compared to AR alone, and more burdensome, with a greater impact on daily functioning (47.0% vs 33.3%) and impairment in work and activity (62.0% and 54.9% vs 39.3% and 35.2%, respectively). Of all subjects, 20.5% were receiving AIT at the time of the survey; of these, 36.4% reported moderate or great improvement in sleep due to allergy treatment. Conclusions:In perennial AR sufferers, sleep problems are common and impact on daily functioning, with results indicating a greater burden in those with both AR and AA compared to AR alone.
