To demonstrate the safety and effectiveness of the Shockwave Reducer for treatment of patients with refractory angina pectoris treated with maximally tolerated guideline-directed medical therapy who demonstrate objective evidence of reversible myocardial ischemia in the distribution of the left coronary artery and who are deemed unsuitable for revascularization. A non-randomized single-arm registry will further assess the safety and effectiveness of the Shockwave Reducer in selected subjects with reversible myocardial ischemia in the distribution of the right coronary artery and who are deemed unsuitable for revascularization, subjects without documented obstructive coronary disease and abnormal coronary flow reserve (ANOCA), and subjects who cannot complete an exercise tolerance test due to lower limb amputation (above the ankle) or other physiologic condition with documented chronic mobility or balance issues that require the use of a walking aid.

The study treatment, BAY 3713372, is under development to treat MTAP (methylthioadenosine phosphorylase)-deleted solid tumors. It is thought to work by blocking the protein arginine N-methyltransferase 5 (PRMT5). This may kill the MTAP-deleted cancer cells while sparing the normal cells. The main objective of this first-in-human study is to learn how safe BAY 3713372 is, how the body processes it, and how well it works in people with MTAP-deleted solid tumors. For this, the researchers will study and analyze: - the number of participants who have adverse events (AEs) after receiving different doses of BAY 3713372 and the AE's severity. - the number of participants who experience dose-limiting toxicities (DLTs) after receiving different doses of BAY 3713372, the DLT's severity and how often they happened. A DLT is a pre-defined medical problem caused by a specific dose of a drug that is too severe to continue using that dose. - the total amount of BAY 3713372 in participants' blood (also called AUC) over time after single and multiple doses. - the highest level of BAY 3713372 in participants' blood (also called Cmax) after single and multiple doses. Other than the main objective, researchers will also check for the number of participants who show a response to treatment and how long they live without the cancer getting worse. The study participants will take part in one of the eight distinct groups or "intervention cohorts" of the study. The study will start with a dose escalation phase where distinct groups of participants will receive different doses of BAY 3713372 alone to find the dose that is deemed safe and works best for the participants. When this dose has been found, a larger number of participants will receive BAY 3713372 alone or with other treatments in a dose expansion phase. Participants may take the study treatment as long as they benefit from the treatment without any severe medical problems. Participants will visit the study site: - at least twice before the treatment starts - multiple times when they start taking the treatment - once after 30 days of receiving the last dose and every 9 weeks after that until the cancer worsens, or the participant stops for any other reason During the study, the doctors and their study team will: - check participants' health by performing tests such as blood and urine tests, and checking heart health using an electrocardiogram - check if the participants' cancer has grown and/or spread using computed tomography (CT) or magnetic resonance imaging (MRI) and, if needed, bone scan - take tumor samples The study doctors and their team will contact the participants every 3 months until 2 years after the last participant's last dose or the end of the study to learn about the participant's health.

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.

The purpose of this first-in-human study is to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of AMG 410 when administered alone or in combination with other agents in participants with advanced or metastatic solid tumors harboring KRAS alterations. This is a dose-escalation study in which participants will be assigned to multiple dose levels (DLs) of AMG 410, either as monotherapy or in combination with other agents, followed by expansion cohorts. The goal is to determine the Maximum Tolerated Dose (MTD)-the highest dose with acceptable safety and manageable side effects-or the Recommended Phase 2 Dose (RP2D) of AMG 410 in adult participants with KRAS-altered advanced or metastatic solid tumors.

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. In previous research atomoxetine and oxybutynin showed promising effect at reducing OSA severity, however they reduced arousal threshold, one of the key traits responsible for OSA. Since oxybutynin was used mainly as a hypnotic, but it is burdened by several anti-cholinergic side effects, DAW2020, a hypnotic which prolonged the total sleep time in a previous trial in OSA patients, could be a better candidate to associate with atomoxetine.

The goal of this clinical trial is to test two new behavioral interventions designed to reduce stress and improve spiritual well-being in stressed adults. The main questions it aims to answer are: 1. Can the program decrease stress and improve spiritual well-being? 2. What brain changes accompany participation in the programs? Participants will: 1. Be randomized to either a live online course that meets for 90 minutes every week for 8-weeks, or to a self-paced program. In the self-paced program, participants will receive materials once a week and can work through them at their own pace. Both programs are designed to decrease stress and improve well-being. 2. Complete questionnaires before and after the course. 3. Complete and interview before and after the course. 4. A subset of people will be randomized to complete an MRI scan of their brain before and after the course. Participants will be randomized to either take the course right away, or be put on a wait-list. Those on the wait-list will undergo the testing at 2 timepoints before they start the program.

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.
