    Stereotactic radiotherapy for neovascular age-related macular degeneration: year 2 results of the INTREPID study

  • Popis výsledku v původním jazyce

    PURPOSE: To determine the safety and efficacy of low-voltage, external-beam, stereotactic radiotherapy (SRT) for patients with neovascular age-related macular degeneration (AMD). DESIGN: Randomized, double-masked, sham-controlled, multicenter, clinical trial. PARTICIPANTS: A total of 230 participants with neovascular AMD who received GREATER-THAN OR EQUAL TO 3 ranibizumab or bevacizumab injections within the preceding year and requiring treatment at enrollment. METHODS: Participants received 16 Gray, 24 Gray, or sham SRT. All arms received pro re nata (PRN) ranibizumab for 12 months, with PRN bevacizumab or ranibizumab thereafter. MAIN OUTCOME MEASURES: Mean number of PRN injections; best-corrected visual acuity (BCVA); loss of &lt;15 Early Treatment of Diabetic Retinopathy Study letters; change in optical coherence tomography central subfield thickness; and change in angiographic total lesion area and choroidal neovascularization (CNV) area. RESULTS: At year 2, the 16 and 24 Gray arms received fewer PRN treatments compared with sham (mean 4.5, P = 0.008; mean 5.4, P = 0.09; and mean 6.6, respectively). Change in mean BCVA was -10.0, -7.5, and -6.7 letters for the 16 Gray, 24 Gray, and sham arms, respectively, with 46 (68%), 51 (75%), and 58 participants (79%), respectively, losing &lt;15 letters. Mean central subfield thickness decreased by 67.0 μm, 55.4 μm, and 33.3 μm, respectively. Mean total active lesion area increased by 1.0, 4.2, and 2.7 mm(2), respectively. Mean CNV area decreased by 0.1 mm(2) in all groups. An independent reading center detected microvascular abnormalities in 6 control eyes and 29 SRT eyes, of which 18 were attributed to radiation; however, only 2 of these possibly affected vision.
