Development and Evaluation of Computerized Chemosensory-Based Orbitofrontal Networks Training for T1

The overarching goal of this study phase, Phase II component is to perform a randomized clinical trial of the refined Computerized Chemosensory-Based Orbitofrontal Networks Training for Treatment of Pain [CBOT-Pain (or CBOT-P)] from Phase I, compared to sham Computerized Chemosensory-Based Orbitofr1 expand

The overarching goal of this study phase, Phase II component is to perform a randomized clinical trial of the refined Computerized Chemosensory-Based Orbitofrontal Networks Training for Treatment of Pain [CBOT-Pain (or CBOT-P)] from Phase I, compared to sham Computerized Chemosensory-Based Orbitofrontal Networks Training (CBOT) in Chronic Low Back Pain (CLBP) to determine its short- and long-term effectiveness on Pain, Negative Affect (NA), Cognition and Cortical Brain Structure (PACS), long-term safety, and indications. The investigators will perform a randomized clinical trial of the refined CBOT-P from Phase I, compared to sham CBOT in CLBP. Aim 2.1: To determine if CBOT-P significantly influences: (1) acute and long-term reduction of pain severity, and (2) acute and long-term reduction of negative affect. The hypothesis is that optimized CBOT will produce faster, stronger, and longer-lasting improvements in pain severity, NA severity, cognitive impairments, and sleep and functional outcomes. Aim 2.2 To determine if CBOT-P significantly prevents or reduces progressive shrinkage in the orbitofrontal cortex (OFC), cingulate cortex, and hippocampus. MRI will be acquired at baseline and 6th month. An integrative analysis will be conducted to determine the link between changes in brain structure and cognitive trajectory. The hypothesis is that the CBOT optimized with BCP significantly attenuates shrinkage in OFC and other prefrontal cortex (PFC) regions, compared to the Sham intervention.

Researchers are looking for new ways to treat people with proficient mismatch repair (pMMR) endometrial cancer (EC) that is advanced or recurrent. - EC is a type of cancer that starts in the tissues inside the uterus (womb) - pMMR indicates that certain normal proteins are present in the cancer cells - Advanced means the cancer has spread locally or to other parts of the body (metastatic) and cannot be removed with surgery - Recurrent means the cancer came back after surgery Sacituzumab tirumotecan (also known as sac-TMT) and pembrolizumab are the study medicines. Sac-TMT is an antibody drug conjugate (ADC). An ADC attaches to specific targets on cancer cells and delivers treatment to destroy those cells. The goal of this study is to learn if people who receive sac-TMT with pembrolizumab live longer and without the cancer getting worse compared to people who receive pembrolizumab alone.

This phase III trial compares the effect of adding docetaxel to hormonal therapy and apalutamide versus hormonal therapy and apalutamide alone in treating patients with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Hormone therapy for prostate cancer, also called androgen deprivation therapy (ADT), uses surgery or drugs to lower the levels of male sex hormones in a man's body. This helps slow the growth of prostate cancer. Apalutamide is in a class of medications called androgen receptor inhibitors. It works by blocking the effects of androgen (a male reproductive hormone) to stop the growth and spread of tumor cells. Giving docetaxel in addition to the usual treatment of hormonal therapy and apalutamide may work better in treating patients with metastatic prostate cancer than the usual treatment alone.

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. One group takes BI 1291583 tablets and the other group takes placebo tablets. A placebo tablet looks like the BI 1291583 tablet but does not contain any medicine. Participants take 1 tablet once a day for up to 1 year and 6 months. Participants are in the study for up to 1 year and 8 months. During this time, participants visit the study site up to 10 times and get about 13 phone calls from the site staff. Participants regularly complete a diary on a smartphone about their bronchiectasis symptoms and study doctors regularly check for any changes. The study doctors document when participants experience flare-ups. The number of flare-ups is compared between the participants who receive BI 1291583 and those who receive the placebo. The study doctors also regularly check participants' health and take note of any unwanted effects.

Primary immune thrombocytopenia (ITP) is a condition where the immune system mistakenly destroys platelets, which are cells that help stop bleeding. This leads to a low number of platelets, making it easier to bruise or bleed. The main aim of this study is to learn whether mezagitamab, when given just under the skin (subcutaneously [SC]), is effective in keeping the platelet count of adults with ITP stable when compared to a placebo. A placebo looks like medicine but doesn't have any active ingredients in it. The participants will be treated with mezagitamab for up to 6 months. During the study, participants will visit their study clinic several times. Participants who complete the TAK-079-3002 study or do not have any response to study treatment by week 16 (according to study criteria) will be given the opportunity to participate in a continuation study to receive open label mezagitamab (if they are eligible and the site is able to open the continuation study).
