WT1 peptide-pulsed dendritic cell therapy for wet age-related macular degeneration

Basic Information

Recruitment status Recruiting
Health condition(s) or Problem(s) studiedwet age-related macular degeneration
Date of first enrollment25/11/2021
Target sample size10
Countries of recruitmentJapan
Study typeInterventional
Intervention(s)<WT1 peptide pulsed dendritic cell vaccine> Approximately 10,000,000 WT1 peptide pulsed dendritic cell vaccines are injected intradermally or subcutaneously at a total of 4 sites on either the extensor surfaces of both upper arms~axillae or the anterior surfaces of both thighs. The vaccine may be continued once every 2 weeks unless skip criteria are met. However, the maximum number of doses is 15. <Aflibercept> (1) Dosing Criteria Aflibercept (genetical recombination) 2 mg (0.05 mL) should be administered intravenously once every month for 3 consecutive induction cycles. (2) Additional dosage standard During the treatment period of WT1 peptide-pulsed dendritic cell vaccine, aflibercept intravitreal administration should be started as a fixed dose every 3 months after the 3rd dose (16 weeks after starting treatment), 7th dose (24 weeks after starting treatment), 11th dose (32 weeks after starting treatment), and post-observation period if the following findings are observed. Translated with www.DeepL.com/Translator (free version) 1)Central retinal thickness (CRT) increases by 100 micrometes or more from the minimum value 2)New CNV appears 3)New macular hemorrhage appears

Outcome(s)

Primary OutcomeSafety(Adverse event rate,Rate of serious adverse events)
Secondary Outcome(1) Average change in best-corrected visual acuity from post-treatment (baseline) (2) Amount of change in central retinal thickness (3) Amount of change in lesion area of choroidal neovascularization (4) Delayed hypersensitivity reaction to WT1 peptide (5) WT1-specific immunological monitoring (6) WT1 non-specific immune response
