The Sponsor is studying an investigational medication called danicamtiv to determine if it can help people with genetic and familial dilated cardiomyopathy (DCM). Investigational means that the safety and effectiveness of danicamtiv have not been established. Currently, there are no approved drugs that are designed specifically to treat genetic or familial DCM. The purpose of this study is to evaluate how well danicamtiv works compared to a placebo (sugar pill that looks like danicamtiv pill but does not contain any danicamtiv) and see how safe it is for people with genetic and familial DCM. In DCM, the heart muscle weakens and enlarges, making it harder for the heart to pump blood; this can happen for different reasons. Some people have DCM because of a change in a gene (called genetic DCM). Others may have DCM that runs in their family, even if no specific gene change is found (called familial DCM). The main goals of the study are: - To assess the effect of danicamtiv on cardiac function using echocardiogram. - To evaluate the impact of danicamtiv on exercise capacity - To evaluate the safety and tolerability of danicamtiv Participants will: - Take danicamtiv or placebo every day for approximately 6 months - Visit the clinic about 12 times for initial evaluation, checkups, tests and follow up

This phase III trial compares the effect of adding gemcitabine to intravesical Bacillus Calmette Guerin (BCG) versus intravesical BCG alone in patients with non-muscle invasive bladder cancer that has come back after a period of improvement (recurrent). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill cancer cells. Intravesical BCG is a solution containing the live BCG bacteria that is placed in the bladder via a catheter (intravesical). When the solution comes into direct contact with the bladder wall, it stimulates the body's immune system which kills tumor cells. Giving gemcitabine with intravesical BCG may kill more tumor cells in patients with recurrent non-muscle invasive bladder cancer.

This phase II trial evaluates whether genetic testing in prostate cancer is helpful in deciding which study treatment patients are assigned. Patient cancer tissue samples are obtained from a previous surgery or biopsy procedure and tested for deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) abnormalities or mutations in their cancer. Valemetostat tosylate is in a class of medications called EZH1/EZH2 inhibitors. It blocks proteins called EZH1 and EZH2, which may help slow or stop the spread of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Cabazitaxel injection is in a class of medications called microtubule inhibitors. It works by slowing or stopping the growth of tumor cells. Abiraterone acetate blocks tissues from making androgens (male hormones), such as testosterone. This may cause the death of tumor cells that need androgens to grow. It is a type of anti-androgen. Enzalutamide 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. Lutetium Lu 177 vipivotide tetraxetan is in a class of medications called radiopharmaceuticals. It works by targeting and delivering radiation directly to tumor cells which damages and kills these cells. Assigning patients to targeted treatment based on genetic testing may help shrink or slow the cancer from growing

Osteoporosis is a disease that weakens bones so the bones may break easily. The risk for osteoporosis increases with age in both women and men. Osteoporosis affects 10 million older adults in the US. Osteoporosis is a common cause of broken bones in the hips and legs. Broken bones can lead to disability, nursing home placement, and death. Because of the dire consequences, a broken hip or leg is one of the most dreaded injuries for older adults. Many studies confirm that a simple regimen of exercise, healthy diet and bone-strengthening medications can improve overall recovery after a broken hip or leg. This regimen can prevent a person from becoming disabled, having future fractures, and even prevent death. Many older adults have surgery in a hospital after breaking a hip or leg. Then older adults go to a skilled nursing facility (SNF) for rehabilitation. Care in SNFs varies greatly. Some patients do not receive the regimen that the investigators know is most beneficial to improve bone health and recovery. Even patients who get exercise, healthy diet, and bone-strengthening medication in the SNF, may not continue with the regimen once patients go home. Therefore, the investigators want to implement and test OsteoPorotic fracTure preventION System (OPTIONS). OPTIONS is a program that will integrate the regimen into the care that is provided in SNFs and after discharge to the community. OPTONS will provide information about exercise, diet, and bone-strengthening medication. OPTIONS will provide doctors, clinical staff, patients, and care partners with the information these stakeholders need to carry out the best-practice regimen. The investigators are partnering with PointClickCare, a large cloud-based healthcare software provider, with SNFs and community care sites across the US. The investigators will include 32 SNFs from different US areas. The investigators will flip a coin to assign SNFs to the intervention (OPTIONS) or the control arm (enhanced usual care) of the study. Enhanced usual care is the care that is typically provided in SNFs after a fracture and adding information about a publicly available fall prevention toolkit. The investigators are using an "implementation science" approach that requires the investigators to get input from the OPTIONS study's vast stakeholder community throughout the study. The OPTIONS study's stakeholders include patients, care partners, clinicians, and professional organizations. The research question is, can using OPTIONS in SNFs and in the community after discharge improve physical function and quality of life in older people in the year after a hip or leg fracture? The investigators are measuring patient-reported outcomes. The investigators will include 1553 patients across the 32 facilities. The investigators have selected outcomes that are important to patients. Specifically, the investigators are measuring patient-reported function and quality of life. The investigators are also measuring patient-reported falls and fractures. The investigators will track the number of patients who die during the study. This study's hypothesis is that patients who receive OPTIONS will report better physical function (i.e., can walk and take better care of themselves) than those who receive enhanced usual care. The investigators also hypothesize that patients that receive OPTIONS will report a better quality of life than those who receive enhanced usual care. This study will provide sound data about the effectiveness of OPTIONS. OPTIONS could then be spread to other SNFs and community-based programs. This would ensure that all older people receive the right care after a hip or leg fracture.

In this study, researchers will learn more about a study drug called litifilimab (BIIB059) in participants with cutaneous lupus erythematosus (CLE). The study will focus on participants who have either active subacute CLE or chronic CLE, or both. They may also have systemic lupus erythematosus (SLE). The participants did not respond to antimalarial therapy or had problems with the treatment that made it hard to continue. The main objective of the study is to learn about the effect litifilimab has on lowering the activity of the skin disease. Researchers will measure symptoms of CLE over time using a variety of scoring tools. These include the Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI), the Cutaneous Lupus Activity of Investigator's Global Assessment-Revised (CLA-IGA-R), and the SELENA-SLEDAI Flare Index (SFI). The main questions researchers want to answer are: - How many participants have a score of 0 or 1 on the CLA-IGA-R looking at skin redness after treatment? - How many participants have their skin disease activity go down by at least 70%? Researchers will also learn more about the safety of litifilimab. They will study how participants' immune systems respond to litifilimab. Additionally, they will measure the effect litifilimab and CLE have on the quality of life of participants using a group of questionnaires. The study will be split into 2 parts - Part A and Part B. Both parts will be done as follows: - After screening, participants will be randomized to receive either litifilimab or placebo for the 1st treatment period. A placebo looks like the study drug but contains no real medicine. - Participants will receive either litifilimab or placebo as injections under the skin once every 4 weeks. - The 1st treatment period will be double blinded which means neither the researchers nor the participants will know if the participants are receiving litifilimab or placebo. - This double blinded treatment period will last 24 weeks, after which the 2nd treatment period will begin. - During the 2nd treatment period, all participants will receive litifilimab for 28 weeks. - After completing treatment in this study, participants that qualify will be given the choice to join the Long-Term Extension study, 230LE305. If they do not, they will move into a follow-up safety period that will last up to 24 weeks. - The total study duration for participants will be up to 80 weeks
