About this study
Official title: A First-in-human Study to Evaluate the Safety, Tolerability and Pharmacokinetics, Pharmacodynamics and Preliminary Clinical Activity of BAY 3713372, a Novel 2nd Generation PRMT5 Inhibitor, in Participants With MTAP-deleted Solid Tumors.
The study treatment, BAY 3713372, is under development to treat MTAP (methylthioadenosine phosphorylase)-deleted solid tumors. It is thought to work by blocking the protein arginine N-methyltransferase 5 (PRMT5). This may kill the MTAP-deleted cancer cells while sparing the normal cells.
The main objective of this first-in-human study is to learn how safe BAY 3713372 is, how the body processes it, and how well it works in people with MTAP-deleted solid tumors.

For this, the researchers will study and analyze:
- the number of participants who have adverse events (AEs) after receiving different doses of BAY 3713372 and the AE's severity.
- the number of participants who experience dose-limiting toxicities (DLTs) after receiving different doses of BAY 3713372, the DLT's severity and how often they happened. A DLT is a pre-defined medical problem caused by a specific dose of a drug that is too severe to continue using that dose.
- the total amount of BAY 3713372 in participants' blood (also called AUC) over time after single and multiple doses.
- the highest level of BAY 3713372 in participants' blood (also called Cmax) after single and multiple doses.
Other than the main objective, researchers will also check for the number of participants who show a response to treatment and how long they live without the cancer getting worse.
The study participants will take part in one of the eight distinct groups or "intervention cohorts" of the study. The study will start with a dose escalation phase where distinct groups of participants will receive different doses of BAY 3713372 alone to find the dose that is deemed safe and works best for the participants. When this dose has been found, a larger number of participants will receive BAY 3713372 alone or with other treatments in a dose expansion phase.
Participants may take the study treatment as long as they benefit from the treatment without any severe medical problems.
Participants will visit the study site:
- at least twice before the treatment starts
- multiple times when they start taking the treatment
- once after 30 days of receiving the last dose and every 9 weeks after that until the cancer worsens, or the participant stops for any other reason
During the study, the doctors and their study team will:
- check participants' health by performing tests such as blood and urine tests, and checking heart health using an electrocardiogram
- check if the participants' cancer has grown and/or spread using computed tomography (CT) or magnetic resonance imaging (MRI) and, if needed, bone scan
- take tumor samples
The study doctors and their team will contact the participants every 3 months until 2 years after the last participant's last dose or the end of the study to learn about the participant's health.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The study treatment, BAY 3713372, is under development to treat MTAP (methylthioadenosine phosphorylase)-deleted solid tumors. It is thought to work by blocking the protein arginine N-methyltransferase 5 (PRMT5). This may kill the MTAP-deleted cancer cells while sparing the normal cells.
The main objective of this first-in-human study is to learn how safe BAY 3713372 is, how the body processes it, and how well it works in people with MTAP-deleted solid tumors.
For this, the researchers will study and analyze:
- the number of participants who have adverse events (AEs) after receiving different doses of BAY 3713372 and the AE's severity.
- the number of participants who experience dose-limiting toxicities (DLTs) after receiving different doses of BAY 3713372, the DLT's severity and how often they happened. A DLT is a pre-defined medical problem caused by a specific dose of a drug that is too severe to continue using that dose.
- the total amount of BAY 3713372 in participants' blood (also called AUC) over time after single and multiple doses.
- the highest level of BAY 3713372 in participants' blood (also called Cmax) after single and multiple doses.
Other than the main objective, researchers will also check for the number of participants who show a response to treatment and how long they live without the cancer getting worse.
The study participants will take part in one of the eight distinct groups or "intervention cohorts" of the study. The study will start with a dose escalation phase where distinct groups of participants will receive different doses of BAY 3713372 alone to find the dose that is deemed safe and works best for the participants. When this dose has been found, a larger number of participants will receive BAY 3713372 alone or with other treatments in a dose expansion phase.
Participants may take the study treatment as long as they benefit from the treatment without any severe medical problems.
Participants will visit the study site:
- at least twice before the treatment starts
- multiple times when they start taking the treatment
- once after 30 days of receiving the last dose and every 9 weeks after that until the cancer worsens, or the participant stops for any other reason
During the study, the doctors and their study team will:
- check participants' health by performing tests such as blood and urine tests, and checking heart health using an electrocardiogram

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing BAY 3713372 in people with MTAP-deleted Solid Tumors, run by Bayer at 63 sites in 13 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 28 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 63 sites in United States, Spain, Japan, China, Italy and 8 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Bayer Clinical Trials Contact (18888422937, clinical-trials-contact@bayer.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose Escalation (Master and Intervention Cohort 1): Number of participants with treatment-emergent adverse events (TEAEs) (time frame: From the first administration of study intervention up to 30 days after the last dose of study intervention). The study lists 14 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2026.
