Investigating DNA Damage Response (DDR) Inhibition in Multiple Tumor Types

Welcome to the DDRiver™ website, where you can find out more about our DDRiver™ clinical trials program. The program includes different investigational drugs being studied in various types of cancer.

Studies of these investigational drugs are sponsored by EMD Serono, the healthcare business of Merck KGaA, Darmstadt, Germany, in the US and Canada.

The DDRiver Clinical Trials Program

The DDRiver™ clinical trials program includes different investigational drugs that are designed to block (inhibit) a specific process in the body involved in cancer called the DNA damage response (DDR) pathway.

These investigational drugs are being studied in clinical trials to find out more about their potential efficacy against tumors and their potential side effects.

These investigational drugs have not yet been proven to be safe and effective. There is no guarantee that any of these investigational drugs will be approved for use in the future. The DDRiver™ website only highlights studies targeting key components of the DDR pathway that are sponsored by EMD Serono, the healthcare business of Merck KGaA, Darmstadt, Germany, in the US and Canada.

More About the DDR Pathway

Every cell in the human body is subject to DNA damage. If that damage is not properly repaired, when these cells divide, they can pass this damage to the next generation of cells. This is called a "mutation" and can lead to the development of cancer.

Healthy cells are able to detect and repair DNA damage or induce cell death if the DNA damage cannot be fixed. This is known as DNA damage response (DDR).

When the DDR is not working well, cells become more sensitive to DNA damage.

In cancer cells, DDR inhibitors have the potential to prevent DNA repair and enhance DNA damage caused by cancer treatments. This means that DDR inhibitors may be able to cause cancer cells to die.

The DDR pathway is a complex network that has evolved to maintain genomic integrity. The DDR pathway has 4 key functions:

Solid Tumors: Tuvusertib

Tuvusertib is an investigational drug that is given by mouth (orally). It is being studied in certain types of solid tumors, based on their properties.

Lung

Lung Cancer: Tuvusertib

Tuvusertib is an investigational drug that is given by mouth (orally). It is being studied in non-squamous non-small cell lung cancer.

Solid

Solid Tumors: Lartesertib

Lartesertib is an investigational drug that is given by mouth (orally). It is being studied in certain types of solid tumors, based on their properties.
