Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
²¹²Pb-DOTAM-GRPR1
In the dose escalation portion, a classic 3+3 design will be utilized for the SAD cohorts and a Boin design for the MAD cohorts. Doses will be increased by approximately 30% in subsequent cohorts. The maximum total dose that may be administered to a subject per cycle is 5.5 mCi +/- 10%.
²¹²Pb-DOTAM-GRPR1
²¹²Pb-DOTAM-GRPR1 is a radioimmunoconjugate comprised of ²¹²Pb, the metal chelator DOTAM (1,4,7,10-Tetrakis(carbamoylmethyl)-1,4,7,10- tetraazacyclododecane) and a GRPR-targeted antagonist.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
8. Serum amylase and/or lipase ≤1.5 x ULN
9. For women of childbearing potential (WOCBP) and men with partners of childbearing potential: be willing to use highly effective methods of contraception or sexual abstinence, if part of participant's lifestyle, throughout the study and for 7 months for WOCBP, 4 months for men after the last \[212Pb\]Pb-DOTAM-GRPR1 administration or for 10 days following \[203Pb\]Pb-DOTAM-GRPR1 administration and participant is not proceeding to 212Pb-DOTAM-GRPR1 treatment, as outlined in protocol.
Participants with Recurrent Glioblastoma:
10. Having first or second glioblastoma recurrence, after standard therapy that includes prior radiation therapy (RT) and at least 12 weeks from completion of RT prior to first administration of 212Pb-DOTAM-GRPR1. In case surgery has been performed for GBM recurrence, the surgery has to be completed at least 4 weeks prior to 212Pb-DOTAM-GRPR1 treatment start, with post-surgery recovery without any complications related to surgical procedure.
11. Presence of 203Pb-DOTAM-GRPR1 uptake by SPECT/CT scan in the tumor lesion(s).
12. Presence of Gadolinium enhancement in the MRI in the tumor lesion(s) shown at the time of diagnosis of tumor recurrence.
