Brief Summary

This is a Phase 1a/1b study of SC-002 in patients with relapsed small cell lung cancer (SCLC) or large cell neuroendocrine carcinoma (LCNEC). SC-002 is an antibody-drug conjugate (ADC) comprised of a monoclonal antibody linked to a potent chemotherapy. The purpose of this study is to assess the safety and tolerability of SC-002 at different dose levels, to determine the highest dose of SC-002 that can be given to patients with SCLC or LCNEC, to evaluate the side effects of SC-002, and to assess the anti-cancer activity of SC-002.

Detailed Description

Part 1A is a dose escalation study in patients with small cell lung cancer or large cell neuroendocrine carcinoma with cytologically confirmed, limited or extensive SCLC or LCNEC that have relapsed or refractory limited or extensive disease following no more than 2 prior chemotherapy regimens. Part 1B is an expansion study where patients will be enrolled and treated in order to further characterize safety and preliminary efficacy in patients with SCLC or LCNEC and further characterize PK, immunogenicity and target expression and possible relationship to clinical outcome.

Label: SC-002

Type: Experimental

Description: Part 1A (Dose Escalation) - IV infusion; safety data will be reviewed prior to dose escalation decision. Dose escalation will complete when recommended dose (RD) is determined. RD will be the maximum tolerated dose (MTD) or lower dose that provides adequate PK exposure, immunogenicity, and preliminary evidence of antitumor activity with tolerability. Part 1B (Dose Expansion) - IV infusion; once MTD and/or RD has been determined in Part 1A, an expansion cohort of approximately 60 patients with SCLC or LCNEC will be enrolled to further characterize the safety profile and clinical activity of the RD. Patients may continue treatment until disease progression, unacceptable toxicity, or withdrawal of consent.
