Inclusion criteria

* Participants must have an advanced, unresectable, or metastatic solid tumor malignancy with a deletion of the methylthioadenosine phosphorylase (MTAP) gene. * Participants must have received, be refractory to, be ineligible for, or be intolerant of available standard care for their cancer.

Exclusion criteria

* Participants must not have a history of any surgical or medical conditions possibly affecting how the study drug is distributed, broken down (metabolized) and removed (excreted or eliminated) from the body. * Participants must not have participated in a clinical study involving a radiolabeled study drug within 12 months prior to admission to the research center. * Participants must not have a current or recent (within 3 months of study drug administration) gastrointestinal disease. * Other protocol-defined Inclusion/
