Efficacy and safety of 0.1% ciclosporin A cationic emulsion in dry eye disease: a pooled analysis of two double-masked, randomised, vehicle-controlled phase III clinical studies.

ABSTRACT: BACKGROUND/AIM:To assess the treatment effect of 0.1% ciclosporin A cationic emulsion (CsA CE) versus vehicle on signs/symptoms of dry eye disease (DED) in various subgroups (moderate-to-severe DED/severe DED/Sjögren's syndrome (SS)/SS with severe DED). METHODS:Pooled data were analysed from two similar phase III studies: SICCANOVE (moderate-to-severe DED) and SANSIKA (severe DED with severe keratitis). In both studies, patients aged ?18 years received CsA CE 0.1% (n=395) or vehicle (n=339) once daily for 6 months. A composite responder efficacy endpoint (corneal fluorescein staining-Ocular Surface Disease Index (CFS-OSDI) at month 6) was used to evaluate the efficacy of CsA CE in alleviating signs/symptoms of DED (response defined as improvement of ?2 grades in CFS and ?30% in OSDI (baseline to month 6)). Human leucocyte antigen-DR (HLA-DR) conjunctival expression was used as a biomarker of ocular surface inflammation. RESULTS:CsA CE-treated patients were significantly more likely to be CFS-OSDI responders than vehicle-treated patients in the overall (OR 1.66, 95% CI 1.11 to 2.50; P=0.015), severe DED (1.80, 1.04 to 3.19; P=0.038) and SS with severe DED (3.37, 1.20 to 11.19; P=0.030) populations. The difference was not significant for CsA CE versus vehicle for the overall Sjögren's population (OR 1.77, CI 0.89 to 3.66; P=0.109). CsA CE also significantly reduced median HLA-DR expression versus vehicle at 6 months (P=0.002). CONCLUSION:Pooled phase III data indicate CsA CE produced significant improvement in signs/symptoms versus vehicle in patients with moderate-to-severe DED (especially in those with severe keratitis), including patients with SS with severe DED.

Project description:IntroductionThe PERSPECTIVE study evaluated, in routine clinical practice, the effectiveness, tolerability and safety of cyclosporine A (CsA) 0.1% cationic emulsion (CE) in controlling severe keratitis in adults with dry eye who remained insufficiently controlled despite artificial tear (AT) use.MethodsA prospective, multicenter, observational study was conducted at 44 ophthalmology clinics across Finland, Germany, Norway, Sweden and the UK. Adults treated with ATs for severe keratitis and dry eye received CsA 0.1% CE therapy (1 drop in both eyes at bedtime) and were followed up at weeks 4, 12 and 24 and at month 12. Primary endpoint was mean [standard deviation (SD)] change from baseline in corneal fluorescein staining (CFS; Oxford Grade Scale) at month 12 following CsA 0.1% CE initiation. Secondary endpoints examined ocular sign and symptom severity and adverse events (AEs).ResultsThe full analysis set included 472 adults (75.9% female). Mean (SD) age was 61.9 (15.41) years. Mean (SD) CFS score was significantly reduced from baseline [2.56 (1.10)] at month 12 [1.10 (SD 1.13); P < 0.0001]. CFS score reductions were statistically significant from week 4, with further incremental decreases reported at study visits through month 12 (P < 0.0001). Severity of eyelid and conjunctival erythema was significantly reduced from baseline at week 4 and maintained through month 12 (P < 0.001). Tear film breakup time increased significantly from baseline at all study visits through month 12 (P < 0.001). Ocular symptom severity was significantly reduced from baseline at all study visits through month 12 (P < 0.001). Overall, 101 treatment-related AEs were reported. Most were mild/moderate (83.6%) and resolved by month 12 (73.3%).ConclusionsIn routine clinical practice, CsA 0.1% CE provided statistically significant reductions in dry eye signs and symptoms. Improvements were seen at week 4 and maintained over 12 months. Treatment tolerability was good and consistent with previous CsA 0.1% CE clinical studies.Trial registrationEU PAS register number: EUPAS 22376.

Project description:Purpose:Preservative-free cationic emulsion-based artificial tears (ATs) or drug vehicles are innovative eye drop formulations with tear film stabilization and drug delivery properties, and valuable in vivo anti-inflammatory and wound healing properties. These ATs have recently reached the market as ATs for the management of dry eye disease (DED) symptoms (i.e., Cationorm) or as a drug vehicle for cyclosporine (Ikervis). The aim of the present study was to explore the mechanism of action underlying the intrinsic anti-inflammatory and wound-healing efficacies harbored by the cationic emulsions of cetalkonium chloride (CE-CKC). Methods:The anti-inflammatory activity of two CE-CKC (0.002% and 0.005% CKC) emulsions was evaluated by assessing the expression of proinflammatory genes and the secretion of various markers in the following human cell types stressed by different agents: peripheral blood mononuclear cells (PBMCs; stimulation with anti-CD3/anti-CD28 or lipopolysaccharide (LPS)), CD4+ T lymphocytes (TCD4; stimulation with anti-CD3/anti-CD28), and a human corneal epithelial cell line (HCE-2; stimulation with LPS). The cells were incubated for 30 min with a 10% dilution of CE-CKC emulsions and then cultured without the emulsions for 24 h or 72 h in the presence of the various challenging agents. The supernatant was collected, and the secreted markers quantitated with flow cytometry or an enzyme-linked immunosorbent assay (ELISA). Gene expression of inflammatory markers was evaluated only in the PBMCs and HCE-2 cells stimulated with LPS. The in vitro protein kinase C (PKC) binding assay for IC50 determination was performed using standard procedures. Results:The CE-CKC emulsions decreased inflammatory gene expression in LPS-stimulated PBMCs (IFN-?, IL-17A, CXCL-9, and TNF?) and LPS-stimulated HCE-2 cells (THBS1 and CCL2). Both CE-CKC emulsions inhibited the secretion of IL-17 (from anti-CD3/anti-CD28-stimulated TCD4), TNF?, IFN-?, and IL-2 (from anti-CD3-/anti-CD28-stimulated PBMCs), and IL-6 and IL-8 (from LPS-stimulated HCE-2). The in vitro PKC binding assay revealed that CKC, the cationic agent, is a specific PKC? inhibitor. In addition, tyloxapol, another excipient, showed some anti-inflammatory activity on IL-6 and IL-8 in the LPS-stimulated HCE-2 cells. Conclusions:This study indicates that the CE-CKC emulsions are able to directly modulate the secretion and expression of proinflammatory cytokines and chemokines. The results also suggest that CKC and tyloxapol are pharmacologically active excipients with potentially beneficial effects in vivo. These data shed new light on the efficacy observed on the DED signs of these CE-CKC emulsions in clinical trials.

Project description:BackgroundDry eye disease (DED) is a chronic ocular surface disease that affects hundreds of millions of people worldwide. Although 0.05% cyclosporine ophthalmic emulsion (CsA OE) has long been prescribed in the U.S. for the treatment of DED, it is not commercially available in China. Our study aims to compare the efficacy and safety profile of 0.05% CsA OE versus vehicle in Chinese patients with moderate to severe DED.MethodsThis was a multicenter, randomized, double-masked, 2-parallel-arm, 3-month phase III study. Patients with moderate to severe DED were randomized to receive twice-daily 0.05% CsA OE or its vehicle, along with unpreserved hypromellose eye drops 3 times per day. Patients were followed up at day 7, 28, 56, and 84, as well as 2 weeks after the medications were discontinued for safety assessment.ResultsA total of 240 patients were randomized. The overall effective rate (OER) and efficacy index were significantly better in the CsA OE than vehicle group at all follow up times (all P < .05), and the OER of CsA OE and vehicle group at month 3 was 70.6% and 27.8%, respectively (P < .001) (primary endpoint). The patients in CsA OE group displayed a significant improvement in dry eye symptoms from day 28 and ocular surface test results from day 7 (all P < .05). The ocular surface disease index scores of 0.05% CsA OE treated patients were significantly better than those treated with vehicle control at day 56 and 84 (P = .0061 and <.001, respectively). Drug related adverse events (AEs) were recorded in 6(5%) and 3(2.5%) patients in the CsA OE and vehicle groups respectively (P = .4061) with ocular pain as the most frequently reported AEs, and it was mostly mild to moderate. There were no detrimental effects on visual acuity, intraocular pressure, or vital signs.ConclusionsTwice-daily instillation of 0.05% CsA OE was effective and well tolerated for the treatment of moderate to severe DED in Chinese population during the 3 months of the study.

Project description:BackgroundCiclosporin is used as an immunosuppressant in current clinical practice but recent research implies novel indications for the drug, such as neuro- and cardioprotection. The intravenous formulation currently on the market, Sandimmune(®) Injection (Sandimmune(®)), uses Cremophor(®) EL as emulsifying excipient. Cremophor(®) EL is known to cause hypersensitivity reactions in some patients, ranging from skin reactions to potentially fatal anaphylactic shock.ObjectivesThe primary objective was to assess if CicloMulsion(®), a Cremophor(®) EL-free lipid emulsion of ciclosporin for intravenous administration, is bioequivalent to Sandimmune(®), and the secondary objective was to compare the tolerability profiles of the two preparations.MethodsThis was a single-centre, open-label, subject-blind, laboratory-blind, single-dose, randomized, two-treatment, two-period, two-sequence crossover study of the pharmacokinetics of two formulations of intravenous ciclosporin. Fifty-two healthy volunteer subjects were administered 5 mg/kg of each of the two formulations of ciclosporin as a 4-h intravenous infusion. The last blood sample was acquired 48 h after the end of the infusion. Bioequivalence assessments according to current guidelines were performed.ResultsThe geometric mean ratios for CicloMulsion(®)/Sandimmune(®) (90 % confidence interval [CI]) were 0.90 (0.88, 0.92) for AUC(0-last) (area under the blood concentration-time curve from time zero to time of last measurable concentration) and 0.95 (0.92, 0.97) for C(max) (maximum blood concentration). For all additional variables analysed, the 90 % CIs were also within the accepted bioequivalence range of 0.80-1.25. One anaphylactoid and one anaphylactic reaction, both classified as serious adverse events, were reported after treatment with Sandimmune(®). No serious adverse events were recorded after treatment with CicloMulsion(®).ConclusionWe have assessed the pharmacokinetics and tolerability of a new Cremophor(®) EL-free lipid emulsion of ciclosporin, CicloMulsion(®), compared to Sandimmune(®). The proportion of adverse events was significantly higher for the Cremophor(®) EL-based product Sandimmune(®). We conclude that CicloMulsion(®) is bioequivalent to Sandimmune(®) and exhibits fewer adverse reactions.
