Clinical Trial Summary

PT217 is a bispecific antibody (bsAb) against human DLL3 (huDLL3) and human CD47 (huCD47). This is a first-in-human, Phase 1/2, open-label, dose-escalation and expansion study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of PT217 in subjects with neuroendocrine carcinomas. Patients with the following tumor types will be eligible for screening: small cell lung cancer (SCLC), large cell neuroendocrine carcinoma of the lung (LCNEC), and extrapulmonary neuroendocrine carcinoma (EP-NEC), including but not limited to neuroendocrine prostate cancer (NEPC) and gastroentero-pancreatic neuroendocrine carcinoma (GEP-NEC). Patients must have progressed after standard therapy (platinum-based chemotherapy) or standard therapy has proven to be ineffective, intolerable or is considered inappropriate.
