Researchers are studying lung mechanics during the early phase of mechanical ventilation in intensive care and during general anesthesia in surgical patients. The study aims to better understand lung compliance and transpulmonary driving pressures using a new, non-invasive PEEP-step method. This method could improve how ventilator settings are personalized to reduce lung injury and complications, addressing a gap in data collected during the critical first hours of ventilation. The study observes two groups ICU patients receiving ventilator treatment and patients undergoing general anesthesia for surgery. In both groups, a PEEP-step method involves adjusting positive end-expiratory pressure PEEP up and down in one or two steps while measuring changes in lung volume and pressures. This is done directly after intubation and repeated during ventilation or surgery when clinical events occur, using specialized software that analyzes data from standard ventilator monitoring equipment. Participants will be monitored continuously during ventilator treatment or surgery. Measurements include lung elastance and transpulmonary driving pressure, collected before, during, and after respiratory care. Clinical data such as blood gases and ventilator settings are recorded without any invasive procedures. The study assesses lung function changes over time, ventilator duration, and postoperative complications, aiming to enhance ventilator therapy and patient outcomes. Total participation time varies with clinical course.

Researchers are evaluating calderasib alone or combined with cetuximab to treat people with advanced solid tumors that have the KRAS G12C mutation, excluding colorectal cancer. This study aims to measure how many participants experience tumor shrinkage or disappearance and compare the responses between the two treatments. It is a phase 2, open-label trial focused on treatment safety and tolerability. Participants will receive calderasib orally with no set limit on treatment cycles. Some participants will also receive cetuximab via intravenous infusion every two weeks. Treatment continues until criteria for stopping the study intervention are met. The trial uses a randomized, parallel design to compare the two experimental arms. Throughout the study, participants will be monitored for tumor response, adverse events, and treatment discontinuations related to side effects. Researchers will also assess progression-free survival, duration of response, and overall survival up to about 76 months. The trial lasts until April 2032, with ongoing safety and efficacy evaluations during this period.

Researchers are studying pulmonary arterial hypertension PAH, a condition where lung blood vessels become thick and narrow, causing high blood pressure in the lungs and making it hard for the heart to work. PAH can cause difficulty breathing and limit activity. While standard treatments help symptoms, they do not stop the disease from worsening. This research focuses on sotatercept, a targeted therapy aimed at specific proteins involved in PAH, to learn about its long-term safety and tolerability when added to usual PAH treatments. Participants in this long-term follow-up study, who previously took part in certain sotatercept trials, may continue receiving sotatercept by subcutaneous injection every three weeks. Those coming from blinded studies start at 0.3 mgkg with possible increases up to 0.7 mgkg, while those from unblinded studies continue their current dose with possible titration to 0.7 mgkg. The study monitors participants over an extended period to assess continued effects alongside their usual PAH therapy. During the study, participants will have regular assessments including monitoring for adverse events, blood tests for blood components and chemistry, body weight, blood pressure, and ECG readings. Researchers will also evaluate exercise capacity, heart function markers, and risk scores related to PAH. The study aims to follow participants for up to approximately 7 to 8 years to understand long-term safety, treatment tolerability, and health changes while using sotatercept with standard PAH care.

Researchers are evaluating the safety, tolerability, and therapeutic effects of BNT113 combined with pembrolizumab compared to pembrolizumab alone as a first-line treatment for patients with unresectable recurrent or metastatic head and neck squamous cell carcinoma HNSCC positive for human papilloma virus 16 HPV16 and expressing the protein PD-L1 with a combined positive score of 1 or higher. This is an open-label, multi-site, Phase IIIII clinical trial consisting of two parts an initial safety run-in phase and a randomized phase. In the safety run-in phase Part A, patients receive BNT113 in combination with pembrolizumab to confirm safety and tolerability at selected dose levels. The randomized phase Part B compares BNT113 combined with pembrolizumab against pembrolizumab monotherapy. Treatments are given by intravenous injection or infusion and continue for up to 24 months. An optional pre-screening phase allows tumor samples to be tested for HPV16 DNA and PD-L1 expression before the main trial screening. Participants will be closely monitored throughout the study. Assessments include safety evaluations, tumor response, and survival outcomes such as overall survival and progression-free survival. Tumor tissue samples must be provided for testing. Researchers will measure treatment-emergent adverse events, response rates, duration of response, and disease control. The study may last up to 48 months, with ongoing safety and efficacy monitoring during and after treatment.

Researchers are comparing long-term outcomes in patients born with pulmonary atresia with intact ventricular septum PA-IVS who have either univentricular or biventricular circulation. The study aims to understand differences in mortality, quality of life, comorbidities, cardiac function, and work capacity between these two groups. This observational study is sponsored by Vastra Gotaland Region and seeks to provide insight into how the heart condition and type of circulation affect patients over time. Participants fall into two groups those with biventricular circulation and those with univentricular circulation. Participants will be invited to complete a Quality of Life questionnaire. A sample of participants, selected based on their place of residence, will be asked to undergo additional tests including ergo-spirometry to measure work capacity, transthoracic echocardiogram, cardiac magnetic resonance imaging, and blood sampling to assess heart function and health. During the study, researchers will review data on comorbidities, quality of life, physical and cardiac capacity, general health related to heart function, and mortality. The main outcome of interest is the difference in comorbidity between the two groups as of September 2024. The study began in July 2024 and will continue through January 2026, with participants contributing information through questionnaires and clinical evaluations during this period.

Researchers are evaluating BGB-16673, an oral drug, in adults with various types of B-cell malignancies such as marginal zone lymphoma, follicular lymphoma, mantle cell lymphoma, chronic lymphocytic leukemia, Waldenstrm macroglobulinemia, diffuse large B-cell lymphoma, and Richters transformation. This study includes Phase 1 dose finding and safety expansion, followed by Phase 2 expansion cohorts to determine recommended doses and further assess safety and efficacy. The study is divided into several parts, starting with Phase 1 dose escalation to find safe dosage levels, including monotherapy dose escalation and safety expansion in selected doses. Phase 2 involves expansion cohorts where participants receive the recommended doses identified in Phase 1 for further safety and efficacy evaluation. Some cohorts include participants who have not received prior BTK inhibitors, and Japanese participants are also enrolled to assess safety. Treatments are orally administered. Participants will undergo regular assessments including monitoring for adverse events, disease response, and drug concentration levels in the blood at various time points. Researchers will measure outcomes such as overall response rate and progression-free survival over approximately three years. Safety and tolerability will be closely tracked, and quality of life questionnaires will be completed at scheduled intervals. Participation may last several years, including follow-up periods to monitor long-term effects.

Researchers are evaluating the safety, tolerability, and distribution of a drug called 177LuLu-ABY-271 in people with HER2-positive metastatic breast cancer. This early phase 1 trial aims to understand how the drug behaves in tumors and key organs, helping to guide future treatments. The study is open-label and randomized, involving female participants aged 18 and older with advanced breast cancer confirmed by specific tests. The trial has two parts. Part A will enroll up to 6 participants to study how the drug is absorbed by tumors and critical organs after a single infusion. Part B will include 15 participants divided into three groups, each receiving a different protein mass dose with varying radioactivity levels, to determine the best dose for future studies. Treatments are given as a single infusion of 177LuLu-ABY-271. Participants will be closely monitored through assessments of side effects and dose-limiting toxicities up to 29 days for Part A and 43 days for Part B. Researchers will also measure radiation absorbed by organs and tumors within 8 days after treatment. The study includes regular evaluations of tumor size, health status, and overall safety. The total participation time varies depending on the study part and dosing schedule.

Researchers are investigating new medicines for children and young people up to 25 years old with relapsed or refractory B-cell non-Hodgkin Lymphoma B-NHL, a type of cancer affecting lymph nodes and organs like the liver or spleen. This international adaptive trial aims to find safer and more effective treatments, focusing on three groups receiving different novel therapies. The study uses a design that allows adding or removing treatments based on their effectiveness and safety in this rare cancer. Participants will receive one of three treatments odronextamab given by intravenous infusion weekly and then less frequently over up to two years loncastuximab tesirine combined with modified R-ICE chemotherapy for up to three cycles or CAR T-cell therapy with details to be confirmed. These treatments are tested in parallel groups, and if a medicine appears ineffective, it may be stopped and replaced by another. The trial allows children to switch groups if their cancer does not respond. During the study, researchers will monitor participants through regular assessments including imaging and laboratory tests to evaluate cancer response and side effects. They will check treatment responses at specific times during treatment cycles and follow patients for at least two years after treatment to monitor long-term outcomes and safety. This includes tracking survival times, adverse events, and overall treatment effectiveness to provide important information about these new therapies.

This research aims to gather long-term safety and effectiveness information for people treated with ibrutinib, a medicine taken by mouth that blocks a specific enzyme called brutons tyrosine kinase. The study focuses on participants who previously took part in ibrutinib studies that have finished and are still receiving ibrutinib treatment, continuing to benefit from it. It is an open-label study, meaning both participants and researchers know the treatment being given. Participants will continue taking ibrutinib capsules daily at the dose they were given in their prior study until the doctor decides the treatment is no longer helpful due to disease progression or side effects, the participant chooses to stop, other treatment options become available, or the study ends. Safety will be monitored throughout, and effectiveness data may be combined with previous study results. No formal testing of hypotheses is planned in this extension. During the study, participants will be regularly monitored for safety and disease status. The main outcome is the number of participants experiencing side effects within 30 days after the last ibrutinib dose or before starting another cancer therapy. Participants may continue treatment until alternative access to ibrutinib is arranged or the study ends, which is planned for December 2029. Researchers will collect ongoing data to understand the long-term effects of ibrutinib treatment.

Researchers are investigating ways to personalize treatment for patients with head and neck squamous cell carcinoma HNSCC, especially those with advanced disease who face a higher risk of treatment failure. This phase III study compares two radiotherapy approaches for patients intended for curative treatment the standard radiotherapy and a hyperfractionated radiotherapy HFX-RT with a higher total radiation dose. The study also aims to improve prognostic and predictive methods by including exploratory analyses such as MRI to evaluate tumor hypoxia, gene profiling, immune profiling, and imaging texture analyses during treatment and follow-up. Participants will be randomly assigned to either standard radiotherapy, which delivers 68.0 Gy in daily fractions of 2.0 Gy, or to hyperfractionated radiotherapy, which delivers 83.0 Gy in smaller doses twice daily 1.22 Gy per fraction over five days per week. The doses vary depending on the tumor volume and lymph node involvement. Patients with lower-risk tumors not eligible for randomization may still participate in the translational research parts of the study. During the study, participants will be closely monitored with regular follow-up visits every three months for two years, then every six months up to five years, focusing on local tumor control. Researchers will collect imaging data, conduct gene and protein analyses, and assess tumor response. The study evaluates treatment effects and tumor behavior over time to better understand and improve outcomes for head and neck cancer patients.
