The main goal of this first in human (FIH) study is to learn about the safety and dosing of GS-9911 when given alone or in combination with an anti-programmed cell death protein 1 (PD-1) monoclonal antibody in participants with advanced solid tumors.
The primary objectives of this study are to:
Assess the safety and tolerability of GS-9911 as monotherapy and in combination with an anti-PD-1 monoclonal antibody in participants with advanced solid tumors
Identify the maximum tolerated dose (MTD)/maximum administered dose (MAD) and the recommended dose for expansion (RDE) of GS-9911 as monotherapy and in combination with an anti-PD-1 monoclonal antibody in participants with advanced solid tumors

Researchers are looking for a better way to treat people who have advanced solid tumors including a specific kind of lung cancer (non-small cell lung cancer, NSCLC).
Advanced solid tumors are types of cancer that have spread to nearby tissue, lymph nodes, and/or to distant parts of the body and that are unlikely to be cured or controlled with currently available treatments.
BAY2862789 works by blocking an enzyme in T-cells, thereby activating them. T-cells are a type of immune cell that are known to have an anti-cancer effect.
The main purpose of this first-in-human study is to learn:
how safe different doses of BAY2862789 are,
the degree to which medical problems caused by BAY2862789 can be tolerated (also called tolerability),
what maximum amount (dose) can be given, and
how BAY2862789 moves into, through and out of the body.
To answer this, the researchers will look at:
the number and severity of medical problems participants have after taking BAY2862789 for each dose level. These medical problems are also referred to as adverse events. An adverse event is considered "serious" when it leads to death, puts the participants' lives at risk, requires hospitalization, causes disability, causes a baby being born with medical problems or is otherwise medically important.
the (average) total level of BAY2862789 in the blood (also called AUC) after intake of single and multiple doses.
the (average) highest level of BAY2862789 in the blood (also called Cmax) after intake of single and multiple doses.
Doctors and their team keep track of all medical problems that participants have during the study, even if they do not think the medical problem might be related to the study treatment.
In addition, the researchers want to know if and how the participants' tumors change after taking BAY2862789.
The study will have two parts. The first part, called dose escalation, is done to find the most appropriate dose that can be given in the second part of the study. For this, each participant will receive one of the increasing doses of BAY2862789.
All participants in the second part of the study, called dose expansion, will receive the most appropriate dose identified from the first part of the study, as tablet by mouth. Participants in both parts of the study, will take the study treatment until their tumor gets worse (also known as 'disease progression'), until they have medical problems, until they leave the study, or until the study is terminated.
Each participant will be in the study for several months, including a test (screening) phase of up to 28 days, few months of treatment depending on the participant's benefit, and a follow up phase after the end of treatment. The following approximate numbers of visits to the study site are planned: two during the screening phase, six in the first treatment month, one to three per month in the following periods.
During the study, the study team will:
take blood and urine samples
do physical examinations
check vital signs such as blood pressure, heart rate, body temperature
examine heart health using ECG (electrocardiogram)
check cancer status using CT (computed tomography) or MRI (magnetic resonance imaging) and, if needed, bone scans
take tumor samples (if required)
pregnancy test
The treatment period ends with a visit no later than 7 days after the last BAY2862789 dose. The study doctors and their team will check the participants' health and any changes in cancer about 30 and 90 days after the last dose and every 12 weeks thereafter. This follow-up period ends if the cancer worsens, if a new anti-cancer treatment is started, or until the participant leaves the study. In addition, the study doctors and their team will contact the participant every 12 weeks to learn about the participant's survival. This ends no later than 12 months after the last participant started treatment or by the end of the study, whichever comes first.
If the study participant benefits from treatment, continuation of treatment with BAY2862789 beyond the duration of this study might be possible.
