Part A, will enroll participants with previously treated advanced MCC, consists of safety-run in cohorts followed by an expansion cohort.

Part B, will enroll participants with advanced MCC not previously treated with anti-programmed cell death 1 (PD1) or anti-programmed cell death ligand 1 (PDL1) agents, consists of safety run-in cohorts followed by an expansion cohort.

Part C will enroll participants with previously treated extensive-stage SCLC and consists of safety-run in cohorts followed by an expansion cohort.

XmAb18087

XmAb18087 ± Pembrolizumab

Benjamin Thompson, MD, PhD

This is a Phase 1b/2, multiple-dose study designed to describe safety and efficacy, and to assess PK and immunogenicity of XmAb18087 monotherapy and in combination with pembrolizumab in participants with metastatic Merkel cell (MCC) or locoregional MCC that has recurred after locoregional therapy with surgery and/or radiation therapy, and mAb18087 monotherapy in participants with extensive-stage small cell lung cancer (SCLC) that has progressed after standard therapies.

This study was terminated by the sponsor. No participants enrolled in Part B.

Safety and Efficacy of XmAb18087 ± Pembrolizumab in Advanced Merkel Cell Carcinoma or Extensive-stage Small Cell Lung Cancer

A Phase 1b/2 Multiple-Dose Study to Evaluate the Safety and Efficacy of XmAb18087 ± Pembrolizumab in Subjects With Advanced Merkel Cell Carcinoma or Extensive-stage Small Cell Lung Cancer (DUET-1-02) Protocol

A treatment-emergent adverse event (TEAE) was any untoward medical occurrence in a participant treated with study drug. The TEAE does not necessarily have a causal relationship with this treatment. A TEAE can therefore be any unfavorable and unintended sign (including a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. TEAEs may include the onset of new illness and the exacerbation of preexisting conditions. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section."

This is a Phase 1, multiple dose, ascending dose escalation study; to define a MTD/RD and regimen consisting of a first "priming" dose and escalated subsequent doses of XmAb18087; to describe safety and tolerability; to assess PK and immunogenicity; and to preliminarily assess anti-tumor activity of XmAb18087 in subjects with advanced NET or GIST.

The study will enroll dosing cohorts to establish a MTD/RD and regimen in subjects with advanced NET or GIST, then enroll additional subjects into separate NET and GIST expansion cohorts to collect additional data on safety and potential efficacy of XmAb18087.
