A Study of PRMT5 Inhibitor BAY 3713372 in Participants With MTAP-deleted Solid Tumors

June 4, 2026 updated by: Bayer

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.

Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing".

This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014. Interested researchers can use www.vivli.org to request access to anonymized patient-level data and supporting documents from clinical studies to conduct research.
