Safety and Efficacy of CLS-TA by Anatomic Location of Inflammation: Results from the Phase 3 PEACHTREE Clinical Trial.

PURPOSE: To explore the efficacy of CLS-TA, a proprietary suprachoroidal injectable suspension of triamcinolone acetonide, in noninfectious uveitis (NIU) with macular edema (ME), categorized by anatomic subtype. METHODS: Patients diagnosed with ME associated with NIU of any etiology and anatomic subtype were eligible for the phase 3 PEACHTREE trial of CLS-TA. Post-hoc analyses were performed, stratified by discrete anatomic subtype of uveitis (anterior, intermediate, posterior, and panuveitis.). RESULTS: Across all anatomic subtypes at 24 weeks, patients receiving CLS-TA at baseline and week 12 demonstrated mean increases in BCVA ranging from +12.1 to +15.9 letters, mean central subfield thickness (CST) improvement ranging from -120.1 µm to -189.0 µm, and IOP changes ranging from +0.5 to +3.1 mmHg. Overall, reports of adverse events were similar among subtypes. CONCLUSIONS: Irrespective of the uveitic anatomic subtype among patients treated for ME associated with NIU, a clinical benefit in participants treated with CLS-TA was demonstrated, with a comparable safety profile.

OCT outcomes as biomarkers for disease status, visual function, and prognosis in diabetic macular edema.

OBJECTIVE: To evaluate disorganization of retinal inner layers (DRIL), as detected on spectral-domain optical coherence tomography (OCT) images, as a biomarker for diabetic macular edema (DME) activity, visual function, and prognosis in eyes with DME. DESIGN: Longitudinal prospective. METHODS: Post hoc correlation analyses were performed on data from a phase 2 clinical trial. Seventy-one eyes of 71 patients with treatment-naive DME received either suprachoroidally administered CLS-TA (proprietary formulation of a triamcinolone acetonide injectable suspension) combined with intravitreal aflibercept or intravitreal aflibercept with a sham suprachoroidal injection procedure. DRIL area, maximum horizontal extent of DRIL, ellipsoid zone (EZ) integrity, and the presence and location of subretinal (SRF) and intraretinal fluid (IRF) were evaluated at baseline and week 24 by certified reading centre graders. RESULTS: At baseline, the area and maximum horizontal extent of DRIL were negatively correlated with best-corrected visual acuity (BCVA; r = -0.25, p = 0.05 and r = -0.32, p =0.01, respectively). Mean baseline BCVA progressively worsened with each ordinal drop in EZ integrity, improved with the presence of SRF, and was invariant to the presence of IRF. DRIL area and maximum extent were significantly decreased at week 24 (-3.0 mm2 [p < 0.001] and -775.8 mm [p < 0.001], respectively. At week 24, decreases in the area and maximum horizontal extent of DRIL were positively correlated with increases in BCVA (r = -0.40, p = 0.003 and r = -0.30, p = 0.04). Improvements in BCVA at week 24 were no different between patients showing improvement in EZ, SRF, or IRF and those showing no improvement or worsening from baseline. CONCLUSIONS: DRIL area and DRIL maximum horizontal extent were demonstrated to be novel biomarkers for macular edema status, visual function, and prognosis in eyes with treatment-naive DME.

Suprachoroidal CLS-TA with and without Systemic Corticosteroid and/or Steroid-Sparing Therapy: A Post-Hoc Analysis of the Phase 3 PEACHTREE Clinical Trial.

PURPOSE: To study the efficacy and safety of suprachoroidal CLS-TA (proprietary suspension of triamcinolone acetonide) in uveitic macular edema (UME) with and without concurrent systemic corticosteroid or steroid-sparing therapy (ST). METHODS: Post hoc analysis of the PEACHTREE phase 3 randomized trial. RESULTS: Among UME patients receiving no ST, at week 24, mean BCVA change was +15.6 letters in 68 CLS-TA patients versus +4.9 letters in 49 sham-control patients (p < .001), while mean CST change was -169.8 µm versus -10.3 µm, respectively (p < .001). Among patients receiving ST, at week 24, mean BCVA change was +9.4 letters in 28 CLS-TA patients versus -3.2 letters in 15 sham-control patients (p = .019), while mean CST change was -108.3 µm versus -43.5 µm, respectively (p = .190). No SAEs related to treatment were reported. CONCLUSIONS: A clinically meaningful benefit of CLS-TA was noted in UME patients, regardless of concurrent ST usage.Abbreviation and AcronymsCST = central subfield thickness; BCVA = best corrected visual acuity; ME = macular edemaI; IVT = intravitreal; AE = adverse event; FA = fluocinolone acetonide; SD-OCT = spectral-domain optical coherence tomography; NIU = noninfectious uveitis; SAE = serious adverse event; TEAE = treatment emergent adverse event; ITT = intent to treat; CI = confidence interval.

Triamcinolone Acetonide Suprachoroidal Injectable Suspension for Uveitic Macular Edema: Integrated Analysis of Two Phase 3 Studies.

INTRODUCTION: Macular edema, a common complication of uveitis, may result in vision loss. The aim of this analysis was to report integrated phase 3 trial data for triamcinolone acetonide injectable suspension for suprachoroidal use (SCS-TA) in the treatment of macular edema secondary to noninfectious uveitis using strict inclusion criteria. METHODS: This analysis included patients with central subfield thickness (CST) ≥ 300 µm and best-corrected visual acuity (BCVA) of ≥ 5 and ≤ 70 Early Treatment Diabetic Retinopathy Study (ETDRS) letters at both screening and baseline who received ≥ 1 study treatment in either PEACHTREE (randomized, double-masked SCS-TA or sham control) or AZALEA (open-label SCS-TA). Patients received SCS-TA 4.0 mg (0.1 ml of 40 mg/ml) or control at baseline and week 12. RESULTS: In the SCS-TA group (n = 95), 47.4% of patients gained ≥ 15 ETDRS letters from baseline to week 24 versus 16.7% of patients in the control group (n = 60; P < 0.001). Mean change in BCVA in the SCS-TA group was 9.6 letters at week 4 and 13.9 letters at week 24. CST also improved rapidly in the SCS-TA group (mean change: - 158.4 µm at week 4), with sustained reduction throughout the study (mean change: - 163.9 µm at week 24 versus - 19.3 µm in the control group; P < 0.001). No treatment-related serious adverse events (AEs) were reported. Incidence of AEs pertaining to elevated intraocular pressure was 12.6% and 15.0% in the SCS-TA and control groups, respectively; incidence of cataract formation/worsening AEs was 7.4% and 6.7%, respectively. CONCLUSION: In this integrated analysis utilizing strict inclusion criteria, SCS-TA was found effective in the treatment of patients with macular edema associated with noninfectious uveitis and was generally well tolerated.

Anatomic Biomarkers of Macular Edema Associated with Retinal Vein Occlusion.

PURPOSE: To assess the relationship between best-corrected visual acuity (BCVA) and anatomic features in patients with macular edema (ME) related to retinal vein occlusion (RVO). DESIGN: Post hoc analysis of 3 clinical trials, which included verified diagnoses, protocol refractions, and the assessment of OCT and fluorescein angiography (FA) images at a masked reading center. PARTICIPANTS: Patients diagnosed with RVO-ME. METHODS: Correlation analyses were performed to determine the correlation between BCVA and macular anatomy at baseline and at 12 and 24 weeks and between changes from baseline to 12 and 24 weeks. MAIN OUTCOME MEASURES: The correlations between BCVA and central subfield thickness (CST), ellipsoid zone (EZ) integrity, intraretinal fluid (IRF), subretinal fluid, central leakage, and ischemia were assessed. RESULTS: In a total of 828 eyes with RVO-ME, the mean age, BCVA, and CST at baseline was 64.7 years, 51.1 letters, and 656.9 µm, respectively. At baseline, a moderate negative correlation was observed between BCVA and CST (r = - 0.56, P < 0.001). At weeks 12 and 24, the mean BCVA of eyes with definitely abnormal (absent) EZ was statistically significantly worse than that of eyes with normal EZ. At week 12, a moderate negative correlation was observed between changes in BCVA and changes in CST (r = - 0.35, P < 0.001), with a similar degree of association noted at week 24 (r = - 0.35, P < 0.001). At weeks 12 and 24, eyes that showed any improvement in central IRF showed a greater improvement in BCVA than eyes that showed no improvement worsening (week 12: 463 eyes, 18.3 letters vs. 177 eyes, 13.0 letters, respectively, P < 0.001) and (week 24: 332 eyes, 20.2 letters vs. 131 eyes, 13.3 letters, respectively, P < 0.001). With respect to the correlation between baseline BCVA and fluorescein leakage or capillary nonperfusion, the Pearson correlation coefficients were - 0.41 (P < 0.001) and - 0.16 (P = 0.060), respectively. CONCLUSIONS: In addition to CST, there are important clinically relevant relationships between BCVA and both OCT and FA anatomic features in patients with RVO-ME.

Extension study of the safety and efficacy of CLS-TA for treatment of macular oedema associated with non-infectious uveitis (MAGNOLIA).

PURPOSE: To assess the extended efficacy and safety of suprachoroidal triamcinolone acetonide injectable suspension (CLS-TA) among patients with macular oedema (ME) secondary to non-infectious uveitis (NIU). METHODS: Patients with uveitic ME were treated with suprachoroidal CLS-TA at baseline and week 12 of the Efficacy and Safety of Suprachoroidal CLS-TA for Macular Edema Secondary to Noninfectious Uveitis: Phase 3 Randomized Trial (PEACHTREE) study. Time to rescue was evaluated over 24 additional weeks for MAGNOLIA. Safety data, visual acuity and retinal central subfield thickness (CST) reduction were also evaluated. Of the 53 eligible patients (46 CLS-TA and 7 control), 33 patients were enrolled (28 CLS-TA and 5 control). RESULTS: Over the entire 48-week period for PEACHTREE and MAGNOLIA, the median time to rescue therapy was 257 days versus 55.5 days for the CLS-TA and sham-control arms, respectively. Of 28 CLS-TA treated patients who participated in MAGNOLIA, 14 (50%) did not require rescue therapy through approximately 9 months after the second treatment. Among CLS-TA patients not requiring rescue, there was a mean gain of 12.1 letters and mean CST reduction of 174.5 µm at week 48. No serious adverse events related to study treatment were observed. CONCLUSION: Approximately 50% of patients did not require additional treatment for up to 9 months following the last CLS-TA administration.

Suprachoroidal triamcinolone acetonide versus rescue therapies for the treatment of uveitic macular oedema: A post hoc analysis of PEACHTREE.

BACKGROUND: This post hoc analysis compared the efficacy and safety of suprachoroidally administered triamcinolone acetonide (CLS-TA) to other commonly available treatments for non-infectious uveitis. METHODS: Results from the PEACHTREE study were compared between subjects randomised to CLS-TA not requiring rescue therapy and those subjects randomised to control, who subsequently required rescue therapy. Endpoints included best corrected visual acuity (BCVA), central subfield thickness (CST), treatment emergent adverse events and intraocular pressure (IOP) related safety findings. RESULTS: In this analysis, there were 83 unrescued CLS-TA subjects and 46 rescued control subjects. At Week 24, 51.9% of the unrescued CLS-TA subjects gained ≥15 letters in BCVA, compared to 37.0% of the rescued control subjects (p = 0.115). Unrescued CLS-TA subjects showed a mean gain of 15.7 versus 10.9 letters in rescued control subjects (p = 0.080). A significantly greater mean reduction in CST was observed for unrescued CLS-TA subjects versus rescued control subjects (174.0 and 148.5 µm; p = 0.040). Of unrescued CLS-TA subjects, 4.9% experienced IOP elevations ≥30 mm Hg at any visit versus 10.9% of rescued control subjects. Further, use of IOP-lowering medications appeared lower in unrescued CLS-TA subjects versus rescued control subjects (7.2% vs. 13.0%). There were no IOP-lowering surgical interventions in either group. CONCLUSION: CLS-TA subjects experienced significantly greater reduction in CST and tended towards greater improvement in BCVA, compared with rescued control subjects. Suprachoroidally administered CLS-TA showed a lower incidence of IOP-related safety findings.

Optical Coherence Tomography Anatomic and Temporal Biomarkers in Uveitic Macular Edema.

PURPOSE: To assess the relationship between best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) features in noninfectious uveitis (NIU)-related macular edema. DESIGN: Clinical cohort study from post hoc analysis of 2 phase 3 clinical trials. METHODS: Correlation and longitudinal treatment analyses were performed. Of 198 patients with NIU, 134 received suprachoroidal CLS-TA (proprietary formulation of a triamcinolone acetonide injectable suspension), and 64 received sham, with 12.9% and 72%, respectively, receiving rescue therapy. RESULTS: At baseline, mean BCVA progressively worsened with each ordinal drop in central subfield ellipsoid zone (EZ) integrity. Eyes with normal baseline EZ experienced greater 24-week change in BCVA versus those with some degree of baseline EZ disruption (11.9 vs 9.4 letters, P = .006). In contrast, eyes with baseline central subfield cystoid spaces and/or subretinal fluid showed more improvement (13.7 or 17.2 letters, respectively) at 24 weeks, versus those without such findings (5.5 [P = .012] or 9.5 letters [P < .001], respectively). Longitudinal modeling for CLS-TA-treated eyes showed that central subfield thickness (CST) reached 90% of maximal improvement by week 3, whereas 90% maximal response in BCVA was not reached until week 9. CLS-TA-treated eyes that showed CST reduction of ≥50 µm at 4 weeks experienced a greater 24-week improvement in BCVA versus those without such an early response (14.6 vs 6.5 letters, P = .006 for difference). CONCLUSIONS: Pretreatment EZ integrity and the presence of central subfield cystoid spaces or subretinal fluid each predict improved therapeutic response to treatment in eyes with NIU. In CLS-TA treated eyes, longitudinal modeling shows CST improvement preceding BCVA improvement.

Visual Acuity in Retinal Vein Occlusion, Diabetic, and Uveitic Macular Edema: Central Subfield Thickness and Ellipsoid Zone Analysis.

PURPOSE: This study assessed relationships between best-corrected visual acuity (BCVA), central subfield thickness (CST), and ellipsoid zone (EZ) integrity in macular edema (ME) patients. DESIGN: Post hoc analysis of 6 clinical trials, which included verified diagnoses, protocol refractions, and reading center assessment of OCT images. PARTICIPANTS: Participants (n = 1063) were diagnosed with ME from retinal vein occlusion (RVO), diabetic retinopathy (DR; diabetic macular edema, DME), or noninfectious uveitis (NIU). METHODS: For CST, 2 clinical trials for each disorder were analyzed. For EZ, 3 studies across 2 disorders were analyzed. MAIN OUTCOME MEASURES: Primary outcomes were correlations between BCVA and CST, and between BCVA and 4 central subfield EZ grades. RESULTS: For baseline BCVA and CST, Pearson correlation coefficients were: ME from RVO, -0.56 (774 eyes; 95% confidence interval [CI], -0.61 to -0.51; P < 0.001); DME, -0.50 (91 eyes; 95% CI, -0.64 to -0.33; P < 0.001); and ME from NIU, -0.38 (198 eyes; 95% CI, -0.49 to -0.26; P < 0.001). Regarding change from baseline to 24 weeks for both BCVA and CST, Pearson correlation coefficients were: ME from RVO, -0.35 (95% CI, -0.43 to -0.27; P < 0.001); DME, -0.30 (95% CI, -0.48 to -0.09; P = 0.006); and ME from NIU, -0.42 (95% CI, -0.53 to -0.29; P < 0.001). Acute and chronic ME showed similar baseline and 24-week change linear correlations. With lower baseline CST, a trend of decreased baseline and 24-week change correlations was found. For central subfield EZ at baseline, mean BCVA progressively worsened with each of 4 EZ grades in 185 eyes with gradable EZ (DME, 41 eyes; NIU, 144 eyes; P ≤ 0.050 for all pairwise comparisons except between normal and questionably abnormal EZ grades). Eyes with normal baseline central subfield EZ showed greater 24-week change in BCVA than those with abnormal baseline EZ (15.00 letters vs. 8.16 letters; P = 0.0005, with baseline BCVA, CST, and age as covariates). CONCLUSIONS: Despite these correlations, CST and EZ integrity, as graded herein, account for the minority of BCVA variation in patients with ME resulting from RVO, DR, and NIU.

Clinical Characterization of Suprachoroidal Injection Procedure Utilizing a Microinjector across Three Retinal Disorders.

Purpose: This study assessed physician-investigator experience with suprachoroidal (SC) injections, an investigational therapeutic administration technique using a 900 or 1100 µm microneedle to inject drugs into the SC space. Methods: Datasets from six clinical trials across three diseases (noninfectious uveitis; diabetic macula edema, and retinal vein occlusion) were assessed. In addition to a user survey, retrospective correlations were performed between procedural variables (needle length), and demographics, and ocular characteristics. Results: In the user survey, 84% (31/37) of physician-investigators did not perceive the SC injections to be meaningfully more challenging than other ocular injections. For the correlation analysis, the 900 µm needle was used for 71% (412/581) of baseline injections, and switching to the longer needle occured in the remaining 29% of baseline injections. No statistical correlations were found between needle lengths and age, race, disorder, refraction, visual acuity, intraocular pressure, retinal central subfield thickness, or lens status. Patient gender and needle length were statistically associated, with 76% (210/275) versus 66% (202/306) of injections administered with 900 µm needles for female and male gender, respectively. Injection quadrant correlated to needle length with 78% (214/275) of superotemporal quadrant injections administered with 900 µm needles, compared with 65% (73/113) of inferotemporal quadrant injections. Conclusions: Both the user survey and the correlation analysis demonstrated that SC injection is well accepted by physician-investigators, and the two needle lengths accommodate a wide range of anatomic and demographic variables. Translational Relevance: These results, along with the presented ex-vivo endoscopic imaging, suggest that SC injection could be readily adopted in clinical practice for targeted compartmentalized delivery of ocular therapeutics.

Comparison of data characterizing the clinical effectiveness of the fluocinolone intravitreal implant (ILUVIEN) in patients with diabetic macular edema from the real world, non-interventional ICE-UK study and the FAME randomized controlled trials.

Objective: To compare the effectiveness and safety of the fluocinolone acetonide (FAc) intravitreal implant between the observational Iluvien Clinical Evidence study in the United Kingdom (ICE-UK) and the Fluocinolone Acetonide in Diabetic Macular Edema (FAME) randomized controlled trials (RCTs) in people with diabetic macular edema (DME). Clinical Trials Registration: NCT00344968. Methods: This study selected patients randomized to receive 0.2 µg/day FAc insert (FAc treated eyes) or sham injection (control eyes) from the FAME RCTs, and patients' first FAc treated eye and non-FAc treated fellow (control) eye from the ICE-UK study. Outcomes included change in visual acuity (VA), central foveal thickness (CFT), and intraocular pressure (IOP). Results: After 12 months follow-up, mean change in VA was 5.0 letters improvement (p < .001) and 1.6 letters improvement (p = .003) in FAME FAc treated and control eyes, and 3.8 letters (p = .012) and -2.1 letters (p = .056) in ICE-UK FAc treated and control eyes, respectively. Mean change in CFT was -144 µm (p < .001) vs -72 µm (p < .001) in FAME FAc treated and control eyes and -113 µm (p < .001) vs -13 µm (p < .001) in ICE-UK FAc treated and control eyes. For eyes with a follow-up of 12 months, 77 (22.3%) and 15 (8.6%) FAME FAc treated and control eyes and 25 (18.7%) and six (4.3%) ICE-UK FAc treated and control eyes required emergent IOP-lowering therapy. Conclusions: Statistically significant improvements in VA 12 months after FAc implantation were observed in both the real-world study and in the RCTs. The improvement in VA and CFT in the RCTs was marginally greater than in the real-world study; however, recruits in the real-world study had more severe visual morbidity at baseline. Whilst there were many changes in the care of people with DME over this time, these data all support the value of treatment with FAc intravitreal implant.

Visual Acuity Outcomes in Diabetic Macular Edema With Fluocinolone Acetonide 0.2 µg/Day Versus Ranibizumab Plus Deferred Laser (DRCR Protocol I).

BACKGROUND AND OBJECTIVE: Visual outcomes of the FAME study (0.2 µg/day fluocinolone acetonide [FAc]) and Protocol I (0.5 mg ranibizumab plus deferred laser) were compared using the area under the curve (AUC) analysis method. PATIENTS AND METHODS: Best-corrected visual acuity (BCVA) data collected during a period of 3 years of follow-up for patients enrolled in FAME or Protocol I were used to calculate AUC of the change in BCVA over a time curve. RESULTS: In the overall population, there was a greater treatment effect for ranibizumab plus deferred laser compared with FAc. However, for subgroups of pseudophakic eyes, eyes with chronic diabetic macular edema (DME), and pseudophakic eyes with chronic DME, ranibizumab plus deferred laser and FAc were not found to be significantly different. The ranibizumab group received a median of 14 injections during a 36-month period compared with a mean of 1.3 injections in the FAc group. CONCLUSION: In pseudophakic and chronic DME subgroups, FAc was comparable to ranibizumab plus deferred laser with fewer injections. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:698-706.].

Sustained delivery fluocinolone acetonide vitreous implants: long-term benefit in patients with chronic diabetic macular edema.

PURPOSE: To present the safety and efficacy of intravitreal implants releasing 0.2 µg/day fluocinolone acetonide (FAc) in patients with chronic versus nonchronic diabetic macular edema (DME). To assess ocular characteristics, anatomic changes, and re-treatment and ancillary therapies that may explain the differential treatment effect seen with intravitreal implants releasing FAc 0.2 µg/day in patients with chronic and nonchronic DME. An overall benefit-to-risk assessment for the FAc 0.2-µg/day and FAc 0.5-µg/day doses has been reported previously. DESIGN: Preplanned subgroup analysis of chronic (duration of diagnosis, ≥3 years) and nonchronic (duration of diagnosis, <3 years) DME in patients from 2 randomized, sham injection-controlled, double-masked, multicenter clinical trials. PARTICIPANTS: Patients with persistent DME despite 1 or more macular laser treatment were randomized 1:2:2 to sham injection (n = 185), FAc 0.2 µg/day (n = 375), or FAc 0.5 µg/day (n = 393). METHODS: Patients received study drug or sham injection and after 6 weeks were eligible for rescue laser. Based on re-treatment criteria, additional masked study drug could be given after 1 year. MAIN OUTCOME MEASURES: Percentage of patients with improvement of 15 letters or more from baseline. Secondary outcomes included other parameters of visual function and foveal thickness. RESULTS: At month 36, the difference between FAc 0.2 µg/day and sham control in the percentage of patients who gained 15 letters or more was significantly greater in chronic DME patients (FAc 0.2 µg/day, 34.0% vs. sham, 13.4%; P<0.001), compared with patients with nonchronic DME (FAc 0.2 µg/day, 22.3% vs. sham, 27.8%; P = 0.275). The greater response in patients with chronic DME was not associated with baseline ocular characteristics, changes in anatomic features, or differences in re-treatment or ancillary therapies. The ocular adverse event profile for FAc 0.2 µg/day was similar regardless of DME duration. CONCLUSIONS: This is the first published analysis correlating duration of diagnosis of DME with treatment effect. In patients with chronic DME, FAc 0.2 µg/day provides substantial visual benefit for up to 3 years and would provide an option for patients who do not respond to other therapy.

Fluconazole prophylaxis in preterm infants: a multicenter case-controlled analysis of efficacy and safety.

BACKGROUND: Fluconazole prophylaxis has demonstrated efficacy in single and multicenter randomized controlled trials without side effects or emergence of resistance. Additional evidence based on incidence of invasive Candida infections, multicenter data, resistance, and safety is desired. METHODS: We conducted a case-control analysis of efficacy and safety of fluconazole prophylaxis from a multicenter database from a neonatal infection study that included 2017 infants <1250 grams from 95 NICUs. Infants receiving intravenous antifungal prophylaxis were pre-identified during enrollment in the parent study. For each infant receiving antifungal prophylaxis (case), three infants not receiving antifungal (controls) were matched by birth weight (± 50 g), by gestational age (± 1 week), gender, and study site. RESULTS: Fluconazole prophylaxis was administered to 127 patients [754 ± 163 g birth weight (BW) and 25.4 ± 1.7 weeks gestational age (GA)] and were compared with 399 control patients (756 ± 163 g BW and 25.5 ± 1.8 weeks GA). Invasive Candida infection occurred in 0.8% (1 of 127) infants who received fluconazole prophylaxis compared with 7.3% (29 of 399) of matched controls (p = 0.006). Candida bloodstream infection occurred in 0.8% (1 of 127) fluconazole prophylaxis infants compared with 5.5% (22 of 399) of matched controls (p = 0.02). There were no differences in late-onset sepsis due to gram-positive or gram-negative organisms, focal bowel perforation, necrotizing enterocolitis, cholestasis, or overall mortality. CONCLUSION: Fluconazole prophylaxis is safe and efficacious in preventing invasive Candida infections. Even in NICUs with a low incidence of invasive Candida infections, antifungal prophylaxis for high-risk infants is a proven and safe opportunity for infection prevention in these patients.

Aqueous levels of fluocinolone acetonide after administration of fluocinolone acetonide inserts or fluocinolone acetonide implants.

PURPOSE: To compare aqueous levels of fluocinolone acetonide (FAc) after administration of FAc inserts or FAc implants (Retisert; Bausch & Lomb, Rochester, NY). DESIGN: Comparison of pharmacokinetics from 2 prospective, interventional, clinical trials. PARTICIPANTS: Thirty-seven patients with diabetic macular edema (DME) (Fluocinolone Acetonide in Human Aqueous [FAMOUS] Study, C-01-06-002) and 7 patients with uveitis (NA-00019318). METHODS: Aqueous FAc was measured after administration of FAc implants or 0.2 µg/day (low dose, ILUVIEN; Alimera Sciences Inc., Alpharetta, GA) or 0.5 µg/day (high dose) FAc inserts. MAIN OUTCOME MEASURES: The primary end point was aqueous levels of FAc. RESULTS: At 1 month after administration for subjects who received 1 treatment, mean aqueous FAc levels were 2.17 (low dose) and 3.03 ng/ml (high dose) for FAc inserts and 6.12 ng/ml for FAc implants with maximum levels of 3.83, 6.66, and 13.50 ng/ml, respectively. At 3 months, mean FAc levels were 1.76, 2.15, and 6.12 ng/ml, respectively. Between 6 and 36 months after low-dose inserts, aqueous levels of FAc were remarkably stable, ranging from 1.18 to 0.45 ng/ml. After high-dose inserts, mean FAc levels were stable between 6 and 24 months, ranging from 1.50 to 0.84 ng/ml and then decreasing to 0.35 ng/ml at 30 months and 0.15 ng/ml at 36 months. In implant-containing eyes, mean FAc levels remained >6 ng/ml through 15 months, the last time point with measurements from at least 6 eyes. CONCLUSIONS: Low- and high-dose FAc inserts both provide stable long-term release of FAc with comparable peak levels in the aqueous: slightly >2 ng/ml for approximately 3 months followed by steady-state levels between 1.0 and 0.5 ng/ml through 36 months for low-dose inserts versus levels between 1.5 and 1.1 ng/ml through 24 months for high-dose inserts. Steady-state aqueous levels after FAc implants were >6 ng/ml. These results provide new insights that aid in the interpretation of efficacy trials and indicate that there is a dose effect for steroid-induced ocular hypertension. In susceptible patients, prolonged aqueous levels of FAc >1 ng/ml moderately increased the risk of glaucoma and levels >6 ng/ml posed a markedly increase risk.

Sustained delivery fluocinolone acetonide vitreous inserts provide benefit for at least 3 years in patients with diabetic macular edema.

OBJECTIVE: To assess long-term efficacy and safety of intravitreal inserts releasing 0.2 µg/d (low dose) or 0.5 µg/d (high dose) fluocinolone acetonide (FAc) in patients with diabetic macular edema (DME). DESIGN: Two randomized, sham injection-controlled, double-masked, multicenter clinical trials. PARTICIPANTS: Subjects with persistent DME despite ≥1 macular laser treatment were randomized 1:2:2 to sham injection (n = 185), low-dose insert (n = 375), or high-dose insert (n = 393). METHODS: Subjects received study drug or sham injection and after 6 weeks were eligible for rescue laser. Based on retreatment criteria, additional study drug or sham injections could be given after 1 year. MAIN OUTCOME MEASURES: Percentage of patients with improvement of ≥15 letters from baseline. Secondary outcomes included other parameters of visual function and foveal thickness. RESULTS: At month 36, the percentage of patients who gained ≥15 in letter score using the last observation carried forward method was 28.7% (low dose) and 27.8% (high dose) in the FAc insert groups compared with 18.9% (P = 0.018) in the sham group, and considering only those patients still in the trial at month 36, it was 33.0% (low dose) and 31.9% (high dose) compared with 21.4% in the sham group (P = 0.030). Preplanned subgroup analysis demonstrated a doubling of benefit compared with sham injections in patients who reported duration of DME ≥3 years at baseline; the percentage who gained ≥15 in letter score at month 36 was 34.0% (low dose; P<0.001) or 28.8% (high dose; P = 0.002) compared with 13.4% (sham). An improvement ≥2 steps in the Early Treatment Diabetic Retinopathy Study retinopathy scale occurred in 13.7% (low dose) and 10.1% (high dose) compared with 8.9% in the sham group. Almost all phakic patients in the FAc insert groups developed cataract, but their visual benefit after cataract surgery was similar to that in pseudophakic patients. The incidence of incisional glaucoma surgery at month 36 was 4.8% in the low-dose group and 8.1% in the high-dose insert group. CONCLUSIONS: In patients with DME FAc inserts provide substantial visual benefit for up to 3 years and would provide a valuable addition to the options available for patients with DME.

Long-term benefit of sustained-delivery fluocinolone acetonide vitreous inserts for diabetic macular edema.

OBJECTIVE: To assess the efficacy and safety of intravitreal inserts releasing 0.2 µg/day (low dose) or 0.5 µg/day (high dose) fluocinolone acetonide (FA) in patients with diabetic macular edema (DME). DESIGN: Two parallel, prospective, randomized, sham injection-controlled, double-masked, multicenter clinical trials. PARTICIPANTS: Subjects with persistent DME despite at least 1 macular laser treatment were randomized 1:2:2 to sham injection (n = 185), low-dose insert (n = 375), or high-dose insert (n = 393). METHODS: Subjects received study drug or sham injection at baseline and after 6 weeks were eligible for rescue laser. Based on retreatment criteria, additional study drug or sham injections could be given after 1 year. MAIN OUTCOME MEASURES: The primary outcome was the percentage of patients with improvement from baseline best-corrected visual acuity (BCVA) in Early Treatment Diabetic Retinopathy Trial (ETDRS) letter score of 15 or more at month 24. Secondary outcomes included other parameters of visual function and foveal thickness (FTH). RESULTS: The percentage of patients with improvement from baseline ETDRS letter score of 15 or more at month 24 was 28.7 and 28.6 in the low- and high-dose insert groups, respectively, compared with 16.2 in the sham group (P = 0.002 for each). Benefit occurred for both doses compared with sham at 3 weeks and all subsequent time points. The mean improvement in BCVA letter score between baseline and month 24 was 4.4 and 5.4 in the low- and high-dose groups, respectively, compared with 1.7 in the sham group (P = 0.02 and P = 0.016). At all time points compared with sham, there was significantly more improvement in FTH. Subjects requiring cataract surgery were more frequent in the insert groups, and their visual benefit was similar to that of subjects who were pseudophakic at baseline. Glaucoma requiring incisional surgery occurred in 3.7%, 7.6%, and 0.5% of the low-dose, high-dose, and sham groups, respectively. CONCLUSIONS: Both low- and high-dose FA inserts significantly improved BCVA in patients with DME over 2 years, and the risk-to-benefit ratio was superior for the low-dose insert. This is the first pharmacologic treatment that can be administered by an outpatient injection to provide substantial benefit in patients with DME for at least 2 years.

Sustained ocular delivery of fluocinolone acetonide by an intravitreal insert.

PURPOSE: To compare Iluvien intravitreal inserts that release 0.2 or 0.5 microg/day of fluocinolone acetonide (FA) in patients with diabetic macular edema (DME). DESIGN: Prospective, randomized, interventional, multicenter clinical trial. PARTICIPANTS: We included 37 patients with DME. METHODS: Subjects with persistent DME despite > or = 1 focal/grid laser therapy were randomized 1:1 to receive an intravitreal insertion of a 0.2- or a 0.5-microg/day insert. MAIN OUTCOME MEASURES: The primary end point was aqueous levels of FA throughout the study with an important secondary outcome of the change from baseline in best-corrected visual acuity (BCVA) at month 12. RESULTS: The mean aqueous level of FA peaked at 3.8 ng/ml at 1 week and 1 month after administration of a 0.5-microg/day insert and was 3.4 and 2.7 ng/ml 1 week and 1 month after administration of a 0.2-microg/day insert. For both inserts, FA levels decreased slowly thereafter and were approximately 1.5 ng/ml for each at month 12. The mean change from baseline in BCVA was 7.5, 6.9, and 5.7 letters at months 3, 6, and 12, respectively, after administration of a 0.5 microg/day-insert and was 5.1, 2.7, and 1.3 letters at months 3, 6, and 12, respectively, after administration of a 0.2-microg/day insert. There was a mild increase in mean intraocular pressure after administration of 0.5-microg/day inserts, but not after administration of 0.2-microg/day inserts. CONCLUSIONS: The FA intravitreal inserts provide excellent sustained intraocular release of FA for > or = 1 year. Although the number of patients in this trial was small, the data suggest that the inserts provide reduction of edema and improvement in BCVA in patients with DME with mild effects on intraocular pressure over the span of 1 year.

Clinical trial of safety and efficacy of INH-A21 for the prevention of nosocomial staphylococcal bloodstream infection in premature infants.

OBJECTIVE: To determine if INH-A21, an intravenous immune globulin (IGIV) derived from donors with high titers of antibody to surface adhesins of Staphylococcus epidermidis and S. aureus prevents late-onset sepsis (LOS) in very low birth weight (VLBW) infants. STUDY DESIGN: In this double-blind, placebo-controlled study, infants with birth weights 500 to 1250 g were randomized to receive up to four doses of INH-A21 (Veronate) or placebo. The primary objective was to determine the safety and efficacy of INH-A21 versus placebo for prevention of S. aureus LOS in VLBW infants. RESULTS: A total of 1983 infants from 95 neonatal intensive care units were randomized, and received at least one dose of study drug. S. aureus LOS developed in 50 of 989 (5%) and 60 of 994 (6%) infants who received placebo or INH-A21, respectively (P = .34). No differences were found in the frequencies of LOS caused by coagulase-negative staphylococci (CoNS), Candida spp, or overall mortality. No adverse events were statistically significantly associated with INH-A21 infusions compared with placebo. CONCLUSION: INH-A21 failed to reduce the incidence of staphylococcal LOS or candidemia in premature infants.

Low incidence of iris pigmentation and eyelash changes in 2 randomized clinical trials with unoprostone isopropyl 0.15%.

OBJECTIVE: To assess whether iris color and eyelash changes occur with the use of unoprostone for 2 years. DESIGN: The 2 clinical trials described herein were prospective, randomized, double-masked, active-controlled, parallel group, multicenter studies. PARTICIPANTS: A total of 1131 patients with primary open-angle glaucoma or ocular hypertension participated in 2 clinical trials and received either unoprostone isopropyl 0.15% (659), timolol maleate 0.5% (331), or betaxolol hydrochloride 0.5% (141), 1 drop per eye twice daily for up to 24 months. METHODS: Color photographs (1:1 magnification) were taken of the iris and eyelid of each patient at baseline and at regular intervals thereafter through month 24 using a standardized camera system. Photography included 7 views of each eye plus a calibration photograph and a patient identification photograph, for a total of 16 photographs per patient per visit. Two independent (masked) readers subjectively compared baseline iris colors to subsequent visits. Side view photographs of the upper and lower eyelashes were used for the eyelash length analysis, with each having sufficient depth of field and a sufficient number of eyelashes in focus. Similarly, frontal eyelash views were used for the eyelash density analysis. MAIN OUTCOME MEASURES: Changes from baseline in iris color and eyelash length and density within and between treatment groups. RESULTS: Seven cases of iris color change (1.06%) were confirmed in patients treated with unoprostone for up to 24 months; no confirmed cases were reported in the timolol or betaxolol groups. In the unoprostone group, cases of iris color change were confirmed at months 12 (1 case), 18 (2 cases), and 24 (4 cases). No clinically relevant differences were observed among treatment groups for changes from baseline in eyelash length or density. CONCLUSION: Although iris hyperpigmentation and abnormal eyelash changes may occur after treatment with unoprostone, the incidence of these events appears to be low in the 2-year clinical study.
