Summary

This early-phase study tested a radioactive drug called 225Ac-SSO110 combined with standard immune checkpoint inhibitors for people with advanced small cell lung cancer or Merkel cell carcinoma. The goal was to check safety and find the right dose. However, the trial was terminated early after enrolling only 2 participants, so no meaningful results are available.
