Condition or disease | Intervention/treatment | Phase |
---|---|---|
Small Cell Lung Carcinoma | Drug: AMG 757 Drug: Pembrolizumab Drug: CRS Mitigation Strategies | Phase 1 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 382 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | 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 in subjects with Small Cell Lung Cancer. The dose exploration phases of the study will estimate the maximum tolerated dose (MTD) or Recommended Phase 2 Dose (RP2D) of AMG 757 either as monotherapy or in combination with pembrolizumab. This will be followed by dose expansion phase to confirm RP2D and to obtain further safety and efficacy data. |
Masking: | None (Open Label) |
Masking Description: | The patient, investigator, investigative staff, medical monitor and care provider will not be masked for the study. |
Primary Purpose: | Treatment |
Official Title: | A Phase 1 Study Evaluating the Safety, Tolerability and Pharmacokinetics of AMG 757 in Subjects With Small Cell Lung Cancer |
Actual Study Start Date : | December 26, 2017 |
Estimated Primary Completion Date : | September 28, 2024 |
Estimated Study Completion Date : | March 27, 2025 |
