The Short Version
ImmunityBio's N-803 (Anktiva) is actively being investigated in multiple cancer types beyond bladder cancer, including pancreatic cancer, non-small cell lung cancer, glioblastoma, and other advanced solid tumors, as confirmed by ClinicalTrials.gov registrations and NCI-sponsored trials. Preliminary efficacy signals in NSCLC have been reported, though definitive Phase 3 proof of efficacy beyond bladder cancer has not yet been established. The claim's "being investigated" component is firmly supported by high-authority sources.
