Erratum ======= In the article “Safety and Efficacy of Extended Therapy with [177Lu]Lu-PSMA: A German Multicenter Study” by Seifert et al. (*J Nucl Med.* 2024;65:[909–916](https://doi.org/10.2967/jnumed.123.267321)), the description of panels B and C of Figure 5 are incomplete. The caption of Figure 5 should read “Kaplan–Meier curves for OS from first [177Lu]Lu-PSMA application for entire cohort (A) and separately for continuous vs. rechallenge treatment cohorts (B). OS curve from start of extended [177Lu]Lu-PSMA therapy separately for continuous vs. rechallenge treatment cohorts (C). The authors regret the error. * © 2025 by the Society of Nuclear Medicine and Molecular Imaging.
