Overview

Study Title

A Phase 1 Study Evaluating the Safety, Tolerability and Pharmacokinetics of AMG 757 in Subjects with Small Cell Lung Cancer

Summary

This is an open-label, ascending, multiple dose, phase 1 study evaluating AMG 757 monotherapy, in combination with anti-PD1 therapy and with additional cytokine release syndrome (CRS) mitigation strategies. AMG 757 will be administered as a short term intravenous (IV) infusion in subjects with small cell lung cancer. AMG 757 is a Half Life Extended (HLE) Bispecific T cell engager (BiTE®) targeting delta-like protein 3 (DLL3)

Objective

Primary: For adult subjects with RR SCLC who progressed or recurred following platinum-based chemotherapy (Indication A) and ED SCLC with ongoing clinical benefit following no more than 6 cycles of platinum-based chemotherapy (Indication B): -Evaluate the safety and tolerability of AMG 757 -Determine the MTD or TP2D of AMG 757 Secondary: For Indications A and B: -Characterize the pharmacokinetics of AMG 757 -Evaluate preliminary anti-tumor activity of AMG 757 Exploratory: For Indications A and B: -Evaluate immunogenicity of AMG 757 -Evaluate protein, nucleic acid and cellular biomarkers in blood pre- and post AMG 757 treatment (eg cytokines, lymphocyte status, CTCs, sDLL3) -Evaluate relationship of baseline target protein expression in tumor tissue, tumor microenvironment characteristics and clinical benefit For Indication B only: -Evaluate the effects of chemotherapy and time elapsed post chemotherapy on "T cell fitness"

Treatments

Therapies

Immunotherapy

Medications

AMG 757 (); Pembrolizumab (Keytruda); Tarlatamab (AMG 757)

  • Prior palliative radiotherapy must have been completed at least 7 days before the first dose of AMG 757
  • Subjects who experienced severe, life-threatening or recurrent (Grade 2 or higher) immune-mediated adverse events or infusion-related reactions including those that lead to permanent discontinuation while on treatment with immune-oncology agents.

  • Participants of both genders of child bearing potential who are not willing to practice an acceptable method(s) of effective birth control while on study through 72 days for females or through 132 days for males after receiving last dose of AMG 757 and (for Part C) 4 months after receiving the last dose of pembrolizumab.
  • Additional criteria apply
