Filter by:This study seeks to better characterize relationships between visual function and the progression (worsening) of geographic atrophy (GA) due to age-related macular degeneration (AMD). The study also will generate new information on the relationship between genetics and GA progression. This is a global, prospective, multicenter, epidemiologic study enrolling 200 participants with GA secondary to AMD. The study visits are scheduled to occur every 6 months. The anticipated duration of the study is up to 60 months.
This study is a Phase III, double-masked, multicenter, randomized, sham injection-controlled study evaluating the efficacy and safety of lampalizumab administered by intravitreal injections in participants with geographic atrophy (GA) secondary to age-related macular degeneration (AMD).

This multicenter, randomized, double-blind, 12-week, placebo-controlled multiple dose study will investigate the safety and tolerability of RO6885247 in adult and pediatric patients with spinal muscular atrophy (SMA).
The primary objective of the study is to examine the clinical efficacy of nusinersen (ISIS 396443) administered intrathecally (IT) to participants with infantile-onset with infantile-onset spinal muscular atrophy (SMA). The secondary objective of the study is to examine the safety and tolerability of nusinersen administered intrathecally to participants with infantile-onset SMA.
The specific aim of this study is to determine whether water ingestion potentiates the pressor response to pseudoephedrine in patients with primary disorders of autonomic failure. The study design will enable us to also evaluate the pressor response to water alone and to pseudoephedrine alone. In a secondary analysis, we will compare the results in patients with two autonomic disorders, pure autonomic failure (PAF) and multiple system atrophy (MSA). We hypothesize that drinking water following a dose of pseudoephedrine will lead to a greater increase in blood pressure than pseudoephedrine alone.
This study is being done to determine the long-term safety and possible benefits of transplanted Human Central Nervous System Stem Cells (HuCNS-SC) for patients with Geographic Atrophy of Age-Related Macular Degeneration. This long-term follow-up study is limited to those individuals who received a transplant of HuCNS-SC cells into one of their eyes as part of the CL-N01-AMD study. No additional study product will be given in this 4-year long-term follow-up study.
This study will assess the safety and efficacy of the brimonidine intravitreal implant in participants with geographic atrophy due to age-related macular degeneration.
Estradiol vaginal tablet is a tablet which hydrates upon contact with moisture, releasing 17ß-estradiol. The estradiol in estradiol vaginal tablet is chemically and biologically identical to the endogenous human estradiol and is therefore classified as a human estrogen. The purpose of this study is to demonstrate clinical endpoint bioequivalence of SPIL's Estradiol vaginal tablet, 10mcg estradiol to the reference listed drug (Vagifem®)which is approved and marketed in the US.
This study will seek to enroll 50 persons who have central or non-central geographic atrophy (GA) associated with age-related macular degeneration (AMD). GA in treated eye must be between 0.75 disk areas (DA) and 8 DA. Eligible participants will be randomly chosen to receive one of the following treatments in the study eye: 1. A 20 μL (440 μg) intravitreal (IVT) injection of sirolimus, or 2. A sham treatment (subconjunctival injection of lidocaine) Participants with two (2) eligible eyes will have one eye randomly assigned to receive intravitreal sirolimus and no sham in the fellow eye. The first injection will begin at Day 0, which may occur on the date of screening/enrollment or up to two weeks following screening/enrollment visit, and every month thereafter. The visit schedule is as follows: 1. A clinical evaluation, including safety measures, will occur monthly. 2. Vision will be measured at the screening/enrollment visit and at 2, 3, 6, 9, 12, 18 and 24 months after the first injection has occurred. 3. Fundus autofluorescence will occur at screening/enrollment and at 2, 6, 12, 18 and 24 months after the first injection has occurred. 4. Fundus color photography and optical coherence tomography will occur at screening/enrollment and at 6, 12, 18 and 24 months after the first injection has occurred. The primary goal is to evaluate whether the persons receiving the sirolimus injections show a slower worsening of geographic atrophy compared to the persons receiving the sham injections. A secondary goal is to evaluate the impact of sirolimus on vision compared to the sham. NOTE: As of May 30, 2014, study injections were discontinued due to safety concerns. No further enrollments will occur and follow-up will continue on all active study participants on a quarterly basis. That is, on visits coinciding with 3 month intervals from date of enrollment.
