Clinical trials

Beamion LUNG-3 study evaluates whether zongertinib, an oral HER2-targeted treatment, can improve outcomes compared with standard adjuvant treatment in adults with completely resected Stage II-IIIB non-small cell lung cancer (NSCLC) whose tumors have activating HER2 tyrosine kinase domain (TKD) mutations. Eligible participants must have undergone curative-intent surgery and received guideline-appropriate perioperative systemic therapy, either neoadjuvant platinum-based chemotherapy with or without immunotherapy, or adjuvant platinum-based chemotherapy. Participants are randomized 1:1 to receive zongertinib or standard of care, which may consist of approved adjuvant immunotherapy or active surveillance, based on local practice guidelines. The main purpose of the study is to determine whether zongertinib can prolong disease-free survival compared to standard treatment. Safety and patient-reported outcomes are also assessed.

This study is open to adults aged between 18 and 80 years of age with a body mass index (BMI) of 18.5 to 42 kg/m². People with or without liver problems can take part in the study. The purpose of this study is to find out how much of a medicine called BI 1291583 gets into the blood of people with and without liver problems. BI 1291583 is being developed to treat people with bronchiectasis, a chronic disease of the lungs. People living with this condition often also have liver problems. Therefore, it is important to find out whether liver problems influence the amount of BI 1291583 that gets into the blood. Study participants receive a single dose of BI 1291583 as a tablet taken by mouth. Participants are divided into 4 groups based on how well their liver works: 1 group without liver problems, and 3 groups with mild, moderate, and severe liver problems. Each participant without liver problems is matched with participants from the other groups based on factors such as age, sex, smoking habits, and body weight to ensure accurate comparisons. Participants are in the study for about 3 months. They stay for 3 days at the study site and also visit the study site up to 9 times. During these visits, the doctors collect information about participants' health. To assess the study endpoints, the doctors regularly take blood samples from the participants. The doctors regularly check participants' health and take note of any unwanted effects.

This study (1438-0003) is open to adults with a tumour in the brain that is positive for the tumour marker delta-like 3 (DLL3). This study is in people with advanced cancer for whom previous treatment was not successful. The purpose of this study is to find out the highest dose of BI 764532 that people with a brain tumour that is positive for DLL3 can tolerate. BI 764532 is an antibody-like molecule that can attach and link together the cancer cells and T-cells of the immune system (DLL3/CD3 bispecific). This may help the immune system fight cancer. Participants get BI 764532 infusions into a vein when starting treatment. If there is benefit for the participants and if they can tolerate it, the treatment is continued. During this time, participants visit the study site at regular intervals. The total number of visits depends on how they respond to and tolerate the treatment. The first study visits include staying to monitor participants' safety. Doctors record any unwanted effects and regularly check the general health of the participants.

This study is open to adults with advanced cancer that cannot be removed by surgery or have spread to other parts of the body. The purpose of this study is to find the highest and most suitable dose of BI 3968621 that people with advanced cancer can tolerate when taken alone or with ezabenlimab. Another purpose is to find out if taking these medicines can stop tumours from growing or make tumours shrink. In this study, BI 3968621 is given to people for the first time. The study is done in 3 parts. The parts are called Part A, Part A2, and Part B. Participants get BI 3968621 alone or in combination with ezabenlimab depending on which part they are in. Part A is done to find the highest and the most suitable dose of BI 3968621 that people with advanced cancer can tolerate. Part A2 is done to find out if taking BI 3968621, at certain dose levels, can stop or slow down tumour growth in participants with kidney cancer. Part B is done to find out how BI 3968621 is tolerated when given with ezabenlimab. BI 3968621 is taken daily as tablets. Ezabenlimab is given as an infusion into a vein once every 3 weeks. Participants can receive study treatment for up to 2 years if they benefit and can tolerate it. During this time, they visit the study site regularly. The number of visits depends on how participants respond to and tolerate the study treatment. Researchers look at the number of participants with certain severe health problems that happen within 3 weeks after the first study treatment. The study doctors check participants' health, take note of unwanted effects, take blood samples, and check how the cancer responds to study treatment.

This study is open to adults with fibrosing interstitial lung disease (ILD) other than idiopathic pulmonary fibrosis (IPF). People can join the study if they have been diagnosed with this condition within the last 3 years and are at risk of developing progressive pulmonary fibrosis (PPF). The purpose of this study is to find out whether a medicine called nerandomilast helps people with fibrosing interstitial lung disease who may be at risk for their disease getting worse. Participants are put into 2 groups randomly, which means by chance. One group takes nerandomilast tablets, and the other group takes placebo tablets. Placebo tablets look like nerandomilast tablets but do not contain any medicine. Nerandomilast is a type of medicine that may help reduce lung function decline and slow disease progression. Participants are in the study for up to about 2 years and 4 months. During this time, they visit the study site regularly. Doctors regularly test lung function using methods like spirometry to measure forced vital capacity (FVC, maximum amount of air a participant can blow out after taking a deep breath) and DLCO (diffusing capacity of the lungs for carbon monoxide; it estimates how well oxygen moves from the lungs into the blood). Additionally, high-resolution computed tomography (HRCT) is performed to monitor how the lung condition is changing over time. The results are compared between the groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

People can join the study if they have been diagnosed with chronic HF at least 3 months before they start on the study. The purpose of this study is to find out whether a medicine called vicadrostat, in combination with another medicine called empagliflozin, helps people with chronic heart failure. In this study, participants are put into 2 groups randomly. Participants have an equal chance of being in either group. One group takes vicadrostat/empagliflozin tablets, and the other group takes placebo/empagliflozin tablets. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take the study medicines as tablets once a day for between about 6 months and about 3.5 years. During this time, they can continue their regular treatment for heart failure. Participants can stay in the study as long as they benefit from treatment and can tolerate it, for a maximum of about 3.5 years. During this time, they visit the study site regularly. The exact number of visits is different for each participant, depending on how long they stay in the study. The study staff may also contact the participants by phone for some visits. Participants also regularly answer questions about their well-being. The doctors document when participants experience worsening of their heart failure symptoms, go to hospital due to heart failure or die during the study. The time until these events are observed is compared between the two treatment groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

This study is open to adults and adolescents aged 12 to under 18 with bronchiectasis. People can participate in this study if they produce sputum and have had flare-ups (also called exacerbations). The purpose of this study is to find out whether a medicine called BI 1291583 helps people with bronchiectasis. Participants are put into 2 groups randomly, which means by chance.

This study is open to people aged 40 years or older who have at least 1 family member with pulmonary fibrosis. Pulmonary fibrosis is a condition where lung tissue becomes scarred, making it harder to breathe. People can join if a lung scan shows early changes in the lung, called interstitial lung abnormalities, which may lead to lung scarring. People with family members who have pulmonary fibrosis are more likely to develop it themselves. That is why it is important to check early for lung changes and find ways to prevent the condition from getting worse. The purpose of this study is to find out whether a medicine called nerandomilast can help slow down changes in the lung in people with a family history of pulmonary fibrosis. Participants are put into one of 2 groups randomly, which means the group is chosen by chance. One group takes nerandomilast tablets, and the other group takes placebo tablets. Placebo tablets look like nerandomilast tablets but do not contain any medicine. Participants take a tablet twice a day for about 2 to 3 years. There is a 3 out of 5 chance that participants will receive nerandomilast instead of the placebo. Participants are in the study for about 2 to 3 years. Participants visit the study site multiple times: more frequently during the first 2 years (about every 3 months), and then every 6 months thereafter. In the 3rd year, participants also have phone calls with the site staff every 3 months. Doctors regularly test lung function and take chest scans to see if the treatment works. The results are compared between the 2 groups to see if nerandomilast helps. The doctors also check participants' health and take note of any unwanted effects.

The study will compare this combination to a placebo version of vicadrostat with empagliflozin. Participants are put into 2 groups randomly, which means by chance. One group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets with empagliflozin. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take a tablet once per day for 2 and a half years and up to 4 years and 3 months. All participants also continue their medication for type 2 diabetes, high blood pressure, and cardiovascular disease. Participants have an equal chance of receiving the study medicine or placebo. Participants are in the study for up to 4 years and 3 months. During this time, they visit the study site regularly. During these visits, doctors collect information about participants' health and take blood samples. The doctors document when participants experience cardiovascular events. The doctors also regularly check participants' health and take note of any unwanted effects.

This study is open to adults aged 18 years and older with different types of HER2+ cancer that has spread and cannot be removed by surgery. People can take part in this study if their tumours show HER2 aberrations and previous treatment was not successful. The purpose of this study is to find a suitable dose of zongertinib that people with different types of HER2+ cancer that has spread can tolerate best when taken together with trastuzumab deruxtecan (T-DXd), with trastuzumab emtansine (T-DM1), with trastuzumab and capecitabine, with zanidatamab, or with mFOLFOX6 (with or without trastuzumab). Another purpose is to check whether zongertinib alone and in combination with other treatments can make tumours shrink. Zongertinib inhibits HER2. HER2 causes cancer cells to grow. In this study, participants receive treatment in cycles. Study participants are treated with zongertinib alone or in combination with other treatments. This study has 2 parts. In Part 1, participants in different groups receive increasing doses of zongertinib. In Part 2, participants are put into different groups by chance. Each group receives a different dose of zongertinib. Every participant has an equal chance of being in each group. During the study, the participants visit the study site regularly. In this study, researchers want to find the highest dose of zongertinib that participants can tolerate when taken together with other treatments. To find this out, researchers look at certain severe health problems that a number of participants have. The doctors regularly check the size of the tumour with imaging methods (CT/MRI) during the study. The doctors also regularly check participants' health and take note of any unwanted effects.

This study is open to adults with different types of advanced cancer. People can take part if previous treatment was not successful, or no treatment exists. The purpose of this study is to find the highest dose of a medicine called BI 1703880 that people with advanced cancer can tolerate when taken together with ezabenlimab. BI 1703880 and ezabenlimab are medicines that may help the immune system fight cancer. In this study, BI 1703880 is given to people for the first time. Participants get BI 1703880 and ezabenlimab as infusions into a vein. During the first 6 weeks, they get BI 1703880 once a week. Later, they get BI 1703880 every 3 weeks.
