The goal of this clinical trial is to learn how three current insomnia therapies (trazodone, daridorexant, cognitive behavioral therapy for insomnia) compare with each other in peri- and post-menopausal women. It will also learn about the safety of the treatments. The main questions it aims to answer are: Which commonly used insomnia therapies are most effective and safe for improving insomnia symptoms in peri- and post-menopausal people? How well do the treatments work for people from different backgrounds, who are at different stages of menopause, and who have different conditions common during menopause (e.g., sleep apnea, mood disturbance, etc.)? What medical problems do participants have when using these treatments? Participants will: Be asked to take trazodone every night, take daridorexant every night, or participate in an online behavioral program for insomnia, for a total of 12 months. Participate in a total of one in-person visit and 7 virtual visits (phone calls) over the 12 months. Wear (and keep) a Fitbit and fill out a daily sleep diary for at least 4 weeks over the 12 months. Fill out online surveys 4 times over the 12 months.

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 lower number of platelets, making it easier to bruise or bleed. The main aim of this study is to check how safe mezagitamab is and how well it is tolerated by adults with chronic primary ITP, if given over a longer time. Other aims are to learn how effective treatment with mezagitamab is and how the body processes it (called pharmacokinetics or PK) over a longer time. Participants of the following previous mezagitamab studies will be invited to join this continuation study: TAK-079-3002 and TAK-079-1004. In this continuation study, participants will receive mezagitamab when certain protocol criteria are met. During the study, participants will visit their study clinic several times.

open study

The ALSTARS trial will be conducted across 20-25 sites in the US and Canada, and will evaluate the safety and efficacy of an investigational treatment called COYA 302 for adults with Amyotrophic Lateral Sclerosis (ALS). COYA 302 is an investigational and proprietary biologic combination therapy with a dual immunomodulatory mechanism of action intended to enhance the anti-inflammatory function of regulatory T cells (Tregs) and suppress the inflammation produced by activated monocytes and macrophages. It is comprised of low dose interleukin-2 (LD IL-2) and DRL_AB (a biosimilar candidate for abatacept). Participants will be randomly assigned to receive one of 2 regimens of COYA 302 or placebo (an inactive substance) in a 1:1:1 ratio for 24 weeks in the double-blind (DB) period. Those who complete this part of the study will be eligible to receive one of the two regimens of COYA 302 for an additional 24 weeks in a blinded active extension phase (EXT). The study will assess changes in disease progression using established ALS clinical outcome measures, including the ALS Functional Rating Scale-Revised (ALSFRS-R), neurofilament (NfL), maximal inspiratory pressure (MIP), slow vital capacity (SVC), and neurological assessments. Additional objectives include evaluation of biomarkers and safety through routine clinical assessments and adverse event monitoring.

The purpose of this research is to address the challenges of diagnosing and long-term management of epilepsy in participants whose seizures are not well captured by standard electroencephalography (EEG) tests and who cannot use or are not able to use more standard monitoring techniques. This research will compare the Minder System to standard of care in providing reliable seizure data. The Minder System was granted De Novo classification by the U.S. Food and Drug Administration (FDA) and is not investigational. Participants will consent to join the study and be implanted with the Minder device; or consent to join the study and continue with their Standard of Care (SOC) as a control group. Participants chose to be implanted with the Minder device will have the device implanted under their scalp. After implantation, participants will be randomly assigned to a group where their treating physician will have access to the EEG data collected by the Minder System or a group where their treating physician does not have access to the EEG data collected by the Minder System. Participants receiving the Minder System will not know which group they are in (blinded) until the study ends. All participants will continue to be followed by their treating physician and undergo assessments and visits until enough information is available to determine a treatment plan or the 6-month follow-up visit.

Some people with pancreatic ductal cancer (PDAC) have a protein called Claudin 18.2 (CLDN18.2) in their tumor. ASP2138 is thought to work by binding to CLDN18.2 and a protein on a type of immune cell called a T-cell. The T-cell "tells" the immune system to attack the tumor. This study is for people with resectable PDAC. Resectable means that the tumor can be removed by surgery. In this study, adults with resectable PDAC will receive an ASP2138 injection just below the skin (subcutaneous) 2 weeks before surgery. After surgery, they will be given standard chemotherapy treatments chosen by their study doctor. These include mFOLFIRINOX, gemcitabine with nab-paclitaxel, or gemcitabine with capecitabine. People will receive chemotherapy treatment for up to 6 months, or until their cancer gets worse, they cannot tolerate the chemotherapy, or they or their study doctor thinks they should stop chemotherapy. People will have a final clinic visit about a month after finishing chemotherapy for health checks.

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).

This research aims to improve the management of exocrine pancreatic insufficiency (EPI), a condition that can develop after pancreatitis, a painful inflammation of the pancreas. EPI occurs when the pancreas does not produce enough enzymes to help the body properly digest food. While pancreatic enzyme replacement therapy (PERT) is commonly used to manage EPI symptoms, it can be challenging for people who rely on feeding tubes. RELiZORB, could help these patients by simplifying the delivery of the enzymes they need. However, RELiZORB has only been studied in people with EPI caused by cystic fibrosis, so its effectiveness in pancreatitis patients remains unknown. This study aims to determine whether RELiZORB is effective for individuals requiring feeding tube support after pancreatitis.
