|Phase III Data for Teva’s QNASL® (beclomethasone dipropionate) Demonstrate Efficacy Profile in Pediatric Patients with Seasonal Allergic Rhinitis|
Additional Phase III Data Show Long-Term Ocular Safety Profile and Support Device Functionality and Reliability
In a two-week, randomized, double-blind, placebo-controlled study, 715 patients with SAR, aged 6-11 years, received once-daily treatment with QNASL® 80 mcg, 160 mcg or placebo. The primary endpoint, the results for which were previously released1, showed significantly greater (p<0.001) improvement in nasal symptoms compared with placebo for both QNASL® 160 mcg and 80 mcg over the two-week treatment period. Additional data reported today further support the efficacy of once-daily dosing with QNASL®. The data show greater (p<0.001) improvements from baseline in patient-reported AM and PM reflective total nasal symptom scores (rTNSS) and patient-reported AM and PM instantaneous total nasal symptom scores (iTNSS) with QNASL® 160 mcg and 80 mcg as compared with placebo (p<0.01). Furthermore, physician-assessed nasal symptom scores (PNSS) show greater improvement in patients receiving QNASL®160 mcg and 80 mcg as compared with placebo (-.096, 95% CI: -1.4, -.05, P<0.001 [80 mcg]); (-.072, 95% CI: -1.2, -.02, P=0.004 [160mcg]). QNASL® was generally well-tolerated in children with a safety profile similar to that of placebo.
“QNASL is a much-needed treatment option for the millions of adults and adolescents suffering from the burdensome symptoms of allergic rhinitis,” said Dr.
Highlights from a study evaluating ocular safety following long-term (52-week) treatment of QNASL® (beclomethasone dipropionate) 320 mcg once-daily were also presented at ACAAI. The primary endpoint, which was previously reported2, showed statistically significant improvements in patient-reported 24-hour rTNSS in patients with PAR, aged 12 years and older, over the first 30 weeks of treatment. Data presented today demonstrate that at 30 and 52 weeks, there were no clinically important differences in intraocular pressure (IOP), which refers to the fluid pressure within the eye, between QNASL® and placebo. If IOP increases beyond the normal range of 10-20 mmHg, patients are at an increased risk of developing glaucoma; however, during treatment with QNASL®, IOP remained within normal range (<21 mmHg) in 94 percent of patients. Treatment with QNASL® had a minimal impact on lens opacities development or progression and there were no reports of development of cataracts during the study. Physician-assessed nasal symptom scores in this study show greater improvement from baseline across 30 and 52 weeks of treatment (-0.63, 95% CI: -1.1, -0.2, P=0.005 [week 30]); (-0.60, 95% CI: -1.0, -0.2, P=0.008 [week 52]).
QNASL® is the first nasal aerosol spray to be available with an integrated dose counter that numerically displays every actuation. Evaluations were conducted to assess the accuracy and reliability of the device. To evaluate the safety and efficacy profile of QNASL®, a six-week, randomized, double-blind, placebo-controlled study was conducted in 474 patients with PAR, aged 12 years and older. As previously published in the Allergy & Asthma Proceedings3, the study showed significantly greater improvement in average patient-reported AM and PM rTNSS compared to placebo. Additional data from this study presented at ACAAI demonstrate the performance, functionality and reliability of the integrated dose counter based on daily patient recordings of actuations and dose counter readings. Agreement between subject recordings, measured by a Nasal Device Performance Diary, and dose counter readings was assessed by discrepancies in the following categories: fire not count, count not fire, count unknown fire and count up unknown fire. Of 41,891 subject-reported actuations, only 159 discrepancies were reported in the diary versus the counter. Nearly 80 percent (79.1) of subjects reported 0 discrepancies, 9.4 percent reported only one discrepancy and 6.4 percent reported just two discrepancies. The dose counter had an overall discrepancy rate of 0.38/100 actuations (0.41 [BDP nasal aerosol group]; 0.34 [placebo group] and the discrepancy rate of fire not count was also low (0.09/100 actuations). These results further suggest that the reliable dose counter will help patients track their remaining medication and help to determine when to replace their device.
“The data presentations at ACAAI further emphasize the safety and efficacy profile of QNASL for the treatment of seasonal and year-round nasal allergies,” said
ABOUT QNASL® (BECLOMETHASONE DIPROPIONATE)
QNASL® Nasal Aerosol is a prescription corticosteroid medication that treats seasonal nasal and year-round nasal allergy symptoms in adults and adolescents 12 years of age and older. It is administered as a nonaqueous or "dry” spray delivered by hydrofluoroalkane (HFA), an environmentally friendly propellant. QNASL® Nasal Aerosol contains beclomethasone dipropionate, which is a man-made (synthetic) corticosteroid. Corticosteroids are natural substances found in the body that reduce inflammation. When QNASL® Nasal Aerosol is sprayed into the nose, it helps reduce the nasal symptoms of allergic rhinitis (inflammation of the lining of the nose), such as stuffy nose, runny nose, itching and sneezing. It is not known whether QNASL® (beclomethasone dipropionate) Nasal Aerosol is safe and effective in children under 12 years of age.
IMPORTANT SAFETY INFORMATION
In clinical studies, nosebleeds and nose ulcers were more common in patients treated with QNASL Nasal Aerosol than patients who received placebo. Some nosebleeds were more severe in patients treated with QNASL Nasal Aerosol than in patients who received placebo. Tell your healthcare provider if you start to have nosebleeds or nasal ulcers after using QNASL Nasal Aerosol.
Thrush (Candida), a fungal infection in your nose, mouth, or throat may occur. Tell your healthcare provider if you have any redness or white colored patches in your mouth or throat.
You should avoid using QNASL Nasal Aerosol until your nose is healed if you have a sore in your nose, you have had recent surgery on your nose or if your nose has been injured, because QNASL Nasal Aerosol may cause slow wound healing.
Some people who use corticosteroids may have eye problems such as increased pressure in the eye (glaucoma) or cataracts. If you have a history of glaucoma or cataracts or have a family history of eye problems, you should have regular eye exams while you use QNASL Nasal Aerosol.
Serious allergic reactions can happen in people taking QNASL Nasal Aerosol. Stop using QNASL Nasal Aerosol and call your healthcare provider right away or get emergency help if you experience shortness of breath or trouble breathing, skin rash, redness, swelling, severe itching, or swelling of your lips, tongue or face.
People are more likely to get infections if they have immune system problems or use drugs, including corticosteroids, which may weaken the body’s ability to fight infections. Avoid contact with people who have infections like chickenpox or measles while using QNASL Nasal Aerosol. Speak to your healthcare provider before using QNASL Nasal Aerosol if you have tuberculosis or untreated fungal, bacterial, or viral infections, or eye infections caused by herpes. Symptoms of an infection include: fever, pain, aches, chills, feeling tired, nausea and vomiting.
A condition in which the adrenal glands do not make enough steroid hormones may occur. Symptoms can include tiredness, weakness, dizziness, nausea and vomiting. Tell your healthcare provider if you experience these symptoms.
Children taking QNASL Nasal Aerosol should have their growth checked regularly, since corticosteroids may slow growth in children.
The most common side effects with QNASL (beclomethasone dipropionate) Nasal Aerosol are nasal discomfort, nosebleeds, and headache.
Tell your healthcare provider if you have any side effect that bothers you or that does not go away.
These are not all of the possible side effects of QNASL Nasal Aerosol. For more information, ask your healthcare provider or pharmacist.
You are encouraged to report negative side effects of prescription drugs to the
