Phase 1 Study of AlphaMedix™ in Adult Subjects With SSTR (+) NET

This dose escalation study will include a maximum of 50 subjects with histologically confirmed NET, a positive somatostatin analogue scan, and no prior history of PRRT therapy. The study will begin with a single ascending dose (SAD) of AlphaMedix™ administered by IV. Subsequent cohorts will receive an incremental 30% increase that will continue until tumor response or DLT. Once tumor response is observed, the study will convert to a Multiple Ascending Dose (MAD) regimen. The MAD treatment regimen will start with the previous safe cohort's dose and will consist of 3 IV administrations of AlphaMedix™ at 8-week intervals. Subsequent cohorts will receive an incremental 30% increase that will continue until tumor response or DLT. The primary objective is to assess the safety and dose limiting toxicity (DLT) using ascending doses of AlphaMedix™. The secondary objectives are to determine the pharmacokinetic properties and preliminary effectiveness of AlphaMedix™.
