PULSAR study: less frequent injections for neovascular AMD may be possible

Posted on

The phase 3 PULSAR study indicated that a higher dose of aflibercept (8 mg) can result in similar safety and efficacy outcomes as the standard lower treatment dose (2 mg). This higher-dose option can reduce the frequency of treatment injections for patients with neovascular age-related macular degeneration (nAMD). The findings were presented at the 2024 ARVO Annual Meeting in Seattle, Washington.

The double-masked, 96-week study randomized patients 1:1:1 to 3 treatment cohorts, each after receiving 3 initial monthly injections:

  1. Aflibercept 2 mg every 8 weeks
  2. Aflibercept 8 mg every 12 weeks
  3. Aflibercept 8 mg every 16 weeks

Change in best corrected visual acuity from baseline at week 96 was +6.6 for aflibercept 2 mg every 8 weeks, +5.6 for aflibercept 8 mg every 12 weeks, and +5.5 for aflibercept 8 mg every 16 weeks. Among those treated with the higher dose regimen, 75% in the 12-week and 70% in the 16-week dosing cohorts who completed 96 weeks of treatment maintained their ³12- and ³16-week dosing intervals.

The researchers reported no new safety signals with aflibercept 8 mg compared with 2 mg.

Among those in the 8-mg dosing cohort who completed 96 weeks of treatment, 47% had dosing intervals of ³20 weeks and 28% had a 24-week dosing interval.

“These findings suggest that aflibercept 8 mg may reduce the need for frequent injections in people with wet AMD,” the authors concluded.
