ciclesonide and apaflurane

The pathology of asthma has clarified that the inflammatory process in the pulmonary airways of the asthmatic patients determines asthma symptom activity primarily. Among the anti-inflammatory agents currently available to treat asthma, glucocorticoids are the most effective, and the topically active agents, inhaled corticosteroids (ICS) are the most efficient. In Japan, two ICS are commercially available: beclomethasone dipropionate (BDP) and fluticasone propionate(FP). Both agents have been widely used and their clinical efficacy (BDP vs FP at half the microgram dose of the BDP) are largely comparable. In order to bring asthmatic patients maximal benefits of the ICS, enhancing treatment compliance and giving educations (including how to use the ICS) are mandatory. New ICS, which have better drug delivery and be topically more potent, will be available.

A hypotonic aqueous nasal spray of ciclesonide is indicated for the treatment of allergic rhinitis (AR). A new nasal aerosol formulation of ciclesonide containing a hydrofluoroalkane propellant delivered via a metered-dose inhaler (CIC-HFA) is currently in clinical development as a potential treatment for AR.. To study the efficacy and safety of once-daily administration of CIC-HFA 80 or 160 μg compared with placebo in subjects 12 years and older with seasonal AR (SAR).. Subjects 12 years and older with a ≥ 2-year history of SAR were randomized in a placebo-controlled, double-blind, parallel-group, multicenter study to receive CIC-HFA 80 or 160 μg or placebo once daily in the morning for 2 weeks. Changes from baseline in reflective total nasal symptom scores (rTNSSs), instantaneous TNSSs (iTNSSs), and reflective total ocular symptom scores (rTOSSs) in subjects with a baseline rTOSS of ≥ 5.00 were evaluated. Treatment-emergent adverse events were monitored throughout the study.. Seven hundred seven subjects were randomized. From baseline, CIC-HFA 80 or 160 μg demonstrated 15.1% and 16.0% reductions in rTNSSs (P < .0001, 3.7% for placebo), 14.3% and 15.4% reductions in iTNSSs (P < .0001, 3.9% for placebo), and 15.7% and 15.0% reductions in rTOSSs (P < .001, 6.8% for placebo). The overall incidence of treatment-emergent adverse events was low and comparable between the CIC-HFA and placebo groups.. In this study, once-daily treatment with CIC-HFA 80 or 160 μg demonstrated statistically significant improvements in nasal and ocular symptoms of SAR. Both doses of active treatment were well tolerated.

Aerosol-based corticosteroid nasal formulations may be preferred over current aqueous nasal sprays by some patients because they traditionally cause less pharyngeal and anterior nose runoff.. To determine the optimal dose, safety, and tolerability of ciclesonide hydrofluoroalkane nasal aerosol in patients with seasonal allergic rhinitis (SAR).. Patients 12 years or older with a history of SAR received ciclesonide hydrofluoroalkane nasal aerosol to a total dose of 75, 150, or 300 microg or placebo once daily (half dose per nostril) for 2 weeks. The primary efficacy assessment was patient-reported average morning and evening reflective (24-hour) total nasal symptom scores (rTNSS). Secondary efficacy assessments included patient-reported average morning and evening instantaneous TNSS (iTNSS), patient-reported morning iTNSS, physician-assessed nasal signs and symptom severity, and Rhinoconjunctivitis Quality of Life Questionnaire responses. Safety and tolerability were also assessed.. Ciclesonide hydrofluoroalkane nasal aerosol demonstrated a statistically significantly greater reduction from baseline in average morning and evening rTNSS (24-hour) vs placebo, with treatment differences as follows: 0.81 (P = .001; 300 microg), 0.90 (P < .001; 150 microg), and 0.66 (P = .01; 75 microg). Improvements in average morning and evening iTNSS and patient-reported morning iTNSS were also significantly improved regardless of dose (P < or = .003 for all ciclesonide groups vs placebo). The incidence of treatment-related adverse events was low (< 1.6% for all) and similar among groups.. Ciclesonide hydrofluoroalkane nasal aerosol demonstrated statistically significant improvements in SAR symptoms vs placebo. On the basis of comparable efficacy and safety profiles observed for all doses, these results suggest that the 75-microg and 150-microg doses of ciclesonide hydrofluoroalkane appear appropriate for further evaluation of efficacy.

Ciclesonide, an intranasal corticosteroid, is administered as a prodrug and is converted to the active metabolite, desisobutyryl ciclesonide, in the upper and lower airways. Previous studies have assessed systemic exposure with the ciclesonide hydrofluoroalkane metered dose inhaler (CIC HFA-MDI) and the ciclesonide aqueous nasal spray (CIC-AQ) formulations. However, systemic exposure with ciclesonide HFA nasal aerosol (CIC-HFA) developed for the treatment of allergic rhinitis has not been investigated.. This study compared the systemic exposure of ciclesonide and desisobutyryl ciclesonide after administration of ciclesonide formulated as an aqueous nasal spray, an HFA nasal aerosol, or as an orally inhaled HFA-MDI.. Healthy adults (aged 18-60 years) were randomly assigned in an open-label, singledose, 3-period crossover design to CIC-AQ 300 microg, CIC-HFA 300 microg, or CIC HFA-MDI 320 microg. Serum samples were collected before study drug administration and at 5, 15, and 30 minutes and 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 14, 18, 22, and 24 hours after dosing. The primary pharmacokinetic parameters were AUC(0-infinity) and C(max) of desisobutyryl ciclesonide. Adverse events were elicited by direct questioning of participants throughout the study.. Thirty volunteers were randomly assigned. Most of the volunteers were male (63% [19/30]) and white (83% [25/30]); the mean age was 36 years and mean weight was 68 kg. Concentrations of desisobutyryl ciclesonide were quantifiable (lower limit of quantitation [LLOQ] = 10 ng/L) in the serum samples of only 5 volunteers (of 30) receiving CIC-AQ, and the highest C(max) value of desisobutyryl ciclesonide was 26.7 ng/L (mean C(max), 15.2 ng/L). The AUC(0-infinity) of desisobutyryl ciclesonide for CIC-AQ was below the LLOQ of the bioanalytic assay. Mean C(max) and AUC(0-infinity) of desisobutyryl ciclesonide were 59.1 ng/L and 397.5 ng . h/L, respectively, for CIC-HFA; and 586.2 ng/L and 2685.0 ng . h/L, respectively, for CIC HFA-MDI. Concentrations of the parent compound, ciclesonide, were below the LLOQ in serum samples after administration of CIC-AQ; they were detectable up to 2 hours after administration of CIC-HFA and up to 4 hours after administration of CIC HFA-MDI. Treatment-emergent adverse events occurred with a low frequency in all 3 treatment groups (30% [9/30] overall) and were mild in intensity as determined by the study investigator.. In this study, compared with that of CIC HFA-MDI, the systemic exposure of desisobutyryl ciclesonide was 10-fold lower after administration of CIC-HFA and at least 40-fold lower after administration of CIC-AQ. All treatments were well tolerated.

Inhaled corticosteroids are recognized as first-line therapy in the management of asthma; however, their use may be limited by systemic and local side-effects. Ciclesonide, a novel pro-drug inhaled corticosteroid, is activated in the lungs and is expected to have less systemic and local side-effects. This study evaluated the efficacy and safety of ciclesonide in hydrofluoroalkane (HFA) compared with beclomethasone dipropionate (BDP) in a chlorofluorocarbon (CFC) formulation in adult patients with moderate to severe asthma.. This was a multicentre, randomized, open-label, parallel-group comparative study. The patients were given 800 microg/day of CFC-BDP in the four-week baseline period. After the baseline period, 319 patients were randomly allocated into three groups which, respectively, received HFA-ciclesonide 400 microg/day (without a spacer), HFA-ciclesonide 800 microg/day (without spacer) and CFC-BDP 800 microg/day (with spacer) for the eight-week treatment period. The primary efficacy variable was morning PEF.. The morning PEF increased by 16.02 L/min in the 400 microg HFA-ciclesonide group, 23.98 L/min in the 800 microg HFA-ciclesonide group and 5.91 L/min in the 800 microg CFC-BDP group. Better outcomes were achieved by the use of 800 microg/day of HFA-ciclesonide compared with 800 microg/day of CFC-BDP (P = 0.001). There was no difference in adverse events between the groups.. In adult patients with moderate to severe asthma, 800 microg/day of HFA-ciclesonide was significantly more effective than 800 microg/day of CFC-BDP. Ciclesonide at doses of 400 microg/day and 800 microg/day was safe and well tolerated.

Drug deposition is an important factor that contributes to safety and efficacy outcomes of inhaled steroid therapy. Ciclesonide is a nonhalogenated, inhaled corticosteroid under investigation for the treatment of asthma. Therefore, this study was performed to assess lung deposition of ciclesonide. Technetium-99m (99mTc)-labeled ciclesonide (where the 99mTc-label is physically dissolved in the ciclesonide-hydrofluoroalkane [HFA] solution aerosol) inhaled by healthy volunteers was analyzed by two-dimensional (2-D) and three-dimensional (3-D) imaging to determine lung deposition. Six healthy volunteers inhaled one puff of 40 microg (exactuator, equivalent to 50 microg ex-valve) ciclesonide for 2-D imaging, and two healthy volunteers inhaled 10 puffs of 40 microg ciclesonide for 2-D and 3-D imaging. The ciclesonide aerosol was administered via metered-dose inhaler (MDI) containing HFA-134a as propellant. The ex-actuator mean (+/- standard deviation) deposition of ciclesonide in the lungs was higher (52% +/- 11%) than in the mouth/pharynx (38% +/- 14%). Two-dimensional and 3-D imaging showed that ciclesonide reached all regions of the lung. Mean percent deposition in peripheral regions (47% and 34%) was higher than in lower central regions (17% and 30%), as revealed by 3-D and 2-D imaging, respectively. Inhalation of up to 400 microg of ciclesonide produced no drug-related side effects. In conclusion, ciclesonide administered via metered-dose inhaler using HFA-134a as a propellant provided high lung deposition (>50%), greater distribution throughout peripheral regions of the lungs, and relatively low oropharyngeal deposition.
