Details and patient eligibility

About

To establish a recommended dose of BAY1862864 Injection and to investigate how the study drug acts in the body, on the cancer cells and how safe it is in patients with advanced non-Hodgkin's lymphoma (NHL)

Full description

The study will be divided into two parts: a "dose-escalation part" to evaluate safety profile and to explore the Maximum tolerated dose (MTD) and an "expansion part" to evaluate further the safety and tumor response profile of BAY1862864 Injection at the selected dose.

Enrollment: 21 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• Subject has failed at least one prior chemo-/immunotherapy-based regimen
• Life expectancy of at least 12 weeks
• Not eligible for, or refused, or failed high-dose therapy combined with autologous stem cell rescue (HDT ASCR)
• Eastern Cooperative Oncology Group (ECOG) performance status of ≤2
• Women of childbearing potential must have negative pregnancy test within seven days before the start of treatment
• Subject was using adequate barrier birth control measures before the study and is willing to continue use of these during the entire course of the study and for the twelve months after the last administration of BAY1862864 Injection
• Adequate bone-marrow, hepatic and renal function

• Current pregnancy or breast-feeding
• Any condition that is unstable or could jeopardize the safety of the subject and his/her compliance with study requirements
• Close affiliation with the investigation site
• Any use by the subject of illicit drugs or other substances that may, in the opinion of the investigator or his/her designated associate(s), have a reasonable chance of contributing to toxicity or otherwise confound the results
