1) Time after the pre-therapeutic dosimetry study; 2) Administered activity;

3) Activity limit calculated from the pre-therapeutic dosimetry to induce 23 Gy kidney dose;

4) Total number of stem cell transplants (SCT); 5) Time of SCT after therapy; 6) Mean absorbed dose;

7) Highest absorbed dose measured in in a contiguous 1 ml volume;

8) Progression-free survival;

9) Overall survival; 10) Censoring date of data on June, 30th, 2016

Individual activities of [177Lu]Pentixather administered for the pre-therapeutic dosimetry study and the measured specific absorbed doses in the kidneys, liver spleen, bone marrow, and tumor are listed for each patients.

If available, the specific absorbed doses measured after treatment with [177Lu]Pentixather are also shown. For the pure ß-emitter 90Y, only estimates for absorbed myeloma doses were derived from pre-therapeutic dosimetry.
