Clinical trials

This is an open-label, nonrandomized, multicenter study conducted in two sequential parts: an initial Phase 2 Dose Optimization Period followed by the Phase 3 Diagnostic Performance Period. After the optimal administered activity and imaging time window are selected in Phase 2, Phase 3 will enroll participants with recently diagnosed PCa who are at least high risk or have suspected metastatic disease and are eligible for radical prostatectomy with pelvic lymph node dissection (RP+PLND). Safety assessments throughout the study will include monitoring of adverse events, vital signs, ECGs, and clinical laboratory parameters. Participants will be enrolled sequentially in a nonrandomized manner, with competitive enrollment across study sites.

This is a multi-center, non-randomized, open-label, dosimetry and dose-escalation, cohort-expansion study of LNTH-2403 administered to subjects with relapsed / refractory (R/R) osteosarcoma. This study consists of 2 phases: (1) a dosimetry and dose escalation phase; and (2) a cohort expansion phase.

This is a multicenter, open-label, prospective Phase 1/2a study to assess safety and tolerability, establish dosimetry and to identify an optimal imaging dose (radioactivity) and imaging time window of 64Cu-LNTH-1363S, and to compare its imaging biodistribution with FAP expression by IHC in patients with sarcomas or GIT cancers. The study will be conducted in 2 parts (Part 1 and Part 2).
