Study of BAY1834942 in Patients With Solid Tumors

An Open-label, Phase 1, First-in-human, Dose Escalation and Expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Tumor Response Profile of the Anti-CEACAM6 Antibody BAY1834942 in Patients With Advanced Solid Tumors

This is an open-label, Phase 1, first-in-human, dose escalation and expansion study designed to assess the safety, tolerability, pharmacokinetics, pharmacodynamics and tumor response profile of the anti-Carcinoembryonic-antigen-related-cell-adhesion-molecule-6 (CEACAM6) antibody BAY1834942 in patients with advanced solid tumors known to have a prevalence for CEACAM6 expression.

The study consists of dose escalation and a tumor type-specific expansion.

Study Overview

• Status: Completed
• Conditions: Advanced CEACAM6-expressing Solid Tumors
• Intervention / Treatment: Drug: BAY1834942

Detailed Description

The primary objectives of the study are to evaluate and characterize the tolerability and safety profile of repeated doses of BAY1834942, and to characterize the pharmacokinetics of BAY1834942 after single dose.

Secondary objectives are to evaluate the tumor response profile, pharmacodynamics, pharmacokinetics and immunogenicity after multiple doses of the drug.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Patients with Solid tumors; Dose escalation with patients having solid tumors. Patients receive escalating doses of BAY1834942 intravenously for 1 hour on Day 1 of each 21-day cycle (Q3W). If the Q3W scheme does not result in sufficient exposure, the scheme is replaced with an once-weekly (QW) dosing scheme.	Drug: BAY1834942; Dose escalation: Sequential dose levels . Dose expansion (except for low-dose expansion): With maximum tolerated dose (MTD) identified in dose escalation part.; Other Names: Anti-CEACAM6 antibody
Experimental: Patients with Gastric cancer; Expansion with patients having gastric and/or gastroesophageal adenocarcinoma: Patients receive BAY1834942 intravenously for 1 hour according to dosing scheme decided in escalation part.	Drug: BAY1834942; Dose escalation: Sequential dose levels . Dose expansion (except for low-dose expansion): With maximum tolerated dose (MTD) identified in dose escalation part.; Other Names: Anti-CEACAM6 antibody
Experimental: Patients with Colorectal cancer; Expansion with patients having colorectal cancer: Patients receive BAY1834942 intravenously for 1 hour according to dosing scheme decided in escalation part.	Drug: BAY1834942; Dose escalation: Sequential dose levels . Dose expansion (except for low-dose expansion): With maximum tolerated dose (MTD) identified in dose escalation part.; Other Names: Anti-CEACAM6 antibody
Experimental: Patients with Non-small-cell-lung cancer; Expansion with patients having adeno Non-small-cell-lung cancer: Patients receive BAY1834942 intravenously for 1 hour according to dosing scheme decided in escalation part.	Drug: BAY1834942; Dose escalation: Sequential dose levels . Dose expansion (except for low-dose expansion): With maximum tolerated dose (MTD) identified in dose escalation part.; Other Names: Anti-CEACAM6 antibody
Experimental: Low-dose expansion; Expansion with patients having the same cancer type (gastric cancer, or colorectal cancer, or non-small-cell lung cancer) and receive BAY1834942 intravenously for 1 hour according to dosing scheme decided in escalation part with a dose lower than the maximum tolerated dose (MTD).	Drug: BAY1834942; Dose escalation: Sequential dose levels . Dose expansion (except for low-dose expansion): With maximum tolerated dose (MTD) identified in dose escalation part.; Other Names: Anti-CEACAM6 antibody
