This study looks at whether an interactive online education module can improve knowledge, comfort, and communication about sexual health during pregnancy. Many pregnant individuals experience changes in sexual function and intimacy but may feel uncomfortable discussing these topics or may have misconceptions about what is safe during pregnancy. Participants who are pregnant and receiving routine prenatal care will be randomly assigned to one of two groups. One group will complete an interactive, evidence-based educational module focused on sexual health and intimacy during pregnancy. The other group will review a standard educational article from the American College of Obstetricians and Gynecologists (ACOG) about sexual activity during pregnancy. Participants will complete surveys before and after reviewing the educational material, as well as a follow-up survey two weeks later. These surveys will measure knowledge about sexual health during pregnancy, comfort discussing sexual concerns with healthcare providers, and sexual function. The goal of this study is to determine whether an interactive educational approach can better support pregnant individuals' understanding of sexual health and encourage open communication with healthcare providers during pregnancy.

Nerandomilast is being developed to help people with systemic sclerosis by potentially improving symptoms and slowing disease progression. This study is open to adults who are at least 18 years old and have systemic sclerosis (SSc). People can join the study if they have limited or diffuse cutaneous SSc with disease onset within 7 years of the first non-Raynaud's symptom. The purpose of this study is to find out whether a medicine called nerandomilast helps people with systemic sclerosis. This study also aims to find out how well nerandomilast is tolerated in people with systemic sclerosis. Participants are put into 2 groups randomly, which means by chance. One group takes nerandomilast tablets and the other group takes placebo tablets. Placebo tablets look like nerandomilast tablets but do not contain any medicine. Participants take the tablets twice a day. Participants are in the study for 1 to about 4 years. During this time, they visit the study site regularly and get phone calls from the site staff. During study visits participants regularly have blood samples taken and doctors check changes in skin thickening, lung function, and internal organs, overall health and the safety and tolerability of study treatment in people with SSc. The results are compared between the groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

This study is being done to learn more about a new medicine called PF-08634404. The study team wants to understand how well it works when given alone or with chemotherapy. The study is for adults with early stage or locally advanced non-small cell lung cancer (NSCLC) that may or may not be removable with surgery. The study is seeking participants who: - Are aged 18 years or older - Have either: - Early-stage or locally advanced (Stage II or IIIA/B) NSCLC and are a candidate for neoadjuvant therapy, followed by surgical removal of the tumor. Neoadjuvant therapy is a treatment given as a first step to shrink the tumor before surgery. - Early-stage or locally advanced (Stage II or IIIA/B) NSCLC and are a candidate for adjuvant therapy and did not achieve a pathological complete response (pCR) from approved treatment that was administered before surgery. Adjuvant therapy is an additional cancer treatment given after the primary treatment to lower the risk that the cancer will come back. pCR is defined as absence of viable tumor in all surgically removed samples. - Locally advanced (Stage III) NSCLC that may not be removable with surgery, was treated with concurrent chemoradiotherapy (cCRT), and is a candidate for additional treatment, otherwise known as consolidation therapy. cCRT is chemotherapy and radiation given simultaneously. - Be in good physical condition and have healthy organs based on medical tests. - Do not have known actionable changes in DNA The study has 3 parts and each participant will be assigned to one part by their doctor based on their disease diagnosis: - Part A will test PF-08634404 given with chemotherapy in the neoadjuvant setting, followed by surgery. - Part B will test PF-08634404 alone in adults who already were treated with neoadjuvant chemo-immunotherapy, underwent surgery, and did not achieve pCR per tumor tissue pathology analysis. Neoadjuvant chemo-immunotherapy refers to the combination of chemotherapy with immunotherapy per local standard-of-care, given before surgical removal of the tumor. - Part C will test PF-08634404 alone in adults with unresectable disease who received cCRT and did not have progressive disease. Progressive disease refers to a condition that grows, spreads, or worsens. All treatments will be done at clinical study sites, where a trained medical team will monitor adults during and after each visit.

This phase II trial tests daratumumab given at a reduced frequency with lenalidomide for maintenance therapy for the cost effective treatment of patients with multiple myeloma post stem cell transplant. Darzalex Faspor (also known as Daratumumab-hyaluronidase) is a combination of two drugs used alone or with other drugs to treat adults with certain types of multiple myeloma or light chain amyloidosis. Daratumumab binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Hyaluronidase allows daratumumab to be given by injection under the skin. Daratumumab and hyaluronidase can be given in less time than daratumumab alone, which is given as an infusion. Lenalidomide may stop or slow cancer cells by blocking the growth of new blood vessels necessary for tumor growth. Daratumumab-hyaluronidase is typically given every 4 weeks per standard of care. Giving it every 8 weeks for the first year followed by every 16 weeks for years 2 through 4 in combination with lenalidomide may be equally as effective and reduce costs and treatment visits for patients with multiple myeloma post stem cell transplant.

This phase III trial compares higher dose chemotherapy, with vincristine, dactinomycin and cyclophosphamide, over a shorter amount of time to lower dose chemotherapy plus maintenance, with vincristine, dactinomycin, cyclophosphamide, irinotecan and vinorelbine, over a longer amount of time, along with standard of care surgery and radiation, in patients with newly diagnosed intermediate risk rhabdomyosarcoma. Vincristine and vinorelbine are in a class of medications called vinca alkaloids. They work by stopping tumor cells from growing and dividing and may kill them. Dactinomycin is a type of antibiotic that is only used in cancer chemotherapy (antineoplastic antibiotic). It works by damaging the cell's DNA and may kill tumor cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells. It may also lower the body's immune response. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and DNA repair and may kill tumor cells. It is not yet known if the higher dose chemotherapy over a shorter amount of time or the lower dose chemotherapy with maintenance over a longer amount of time is more effective in the treatment of patient with newly diagnosed, intermediate risk rhabdomyosarcoma.

Some people develop a narrowing of their windpipe (trachea), called benign tracheal stenosis, which can make it hard to breathe. Doctors often treat this by using a bronchoscope-a thin, flexible tube with a camera-to open up the airway or remove scar tissue. While these procedures help patients breathe better, we do not fully understand why the narrowing occurs or how the tissue heals afterward. The purpose of this study is to better understand the biological changes in the airway tissue before and after these standard medical procedures. During the procedure, small samples of tissue that would already be collected as part of normal care will be analyzed in the laboratory. The results may help doctors learn more about airway healing and could guide better treatments in the future.

In this study, researchers will learn more about the safety and effects of BIIB115, also known as salanersen.

In this study, researchers will learn more about the safety and effects of BIIB115, also known as salanersen. Specifically, researchers will learn more about how salanersen works in babies who have already been treated with onasemnogene abeparvovec (OA) after being diagnosed with SMA. Most people with SMA have changes in a gene called survival motor neuron 1, also known as SMN1. These changes lower the amount of SMN protein in their bodies. Without enough of this protein, motor neurons and muscles cannot work properly. A similar gene called SMN2 can help replace some of the lost SMN protein in the body. Salanersen works by helping the SMN2 gene to make more SMN protein. OA works by replacing the missing or abnormal SMN1 gene. Sometimes, OA treatment may not work as well as expected. As a result, researchers are exploring whether giving another drug after OA could lead to better outcomes for people with SMA. In this study, participants will have 2 SMN2 copies. The higher the copy number, the less severe the participant's SMA is. They will also have received treatment with OA by the time they were 42 days old and before showing any symptoms of SMA. The main goal of the study is to learn more about the safety of giving salanersen to babies after OA treatment. Researchers will also learn more about whether salanersen can help make SMA symptoms less serious. The main question researchers want to answer in this study is: • How many participants have adverse events and serious adverse events after treatment? Researchers will also learn more about: - The effects on participants' motor symptoms and how many new movement milestones participants achieve. - How many participants stay free of SMA symptoms. - How much neurofilament protein is found in the blood after treatment. - How much salanersen gets into the fluid surrounding the brain and spinal cord. - How much salanersen gets into the blood. Researchers will use different tests to learn if motor symptoms are changing, including the World Health Organization (WHO) motor milestones and Hammersmith Infant Neurological Examination (HINE) Section 2 motor milestones. The study will be done in 2 parts. Part A will last 1 year while Part B will last up to 4 years. The study will be done as follows: - First, participants will be screened to check if they can join the study. The screening period will be up to 6 months. Participants must have received OA treatment before the age of 42 days and started screening within 6 months of the OA dose. - Participants will be assigned to 1 of 2 treatment groups by chance. This is a "double blind" study which means neither the participants, study doctor, nor site staff will know which treatment group the participants are assigned to. - In this study, salanersen will be given as an intrathecal injection, which is an injection into the fluid surrounding the spine. This is done by a procedure called a lumbar puncture (LP) which involves inserting a needle into the lower back into the space around the spinal cord. - During Part A, one group will receive 80 milligrams (mg) of salanersen while another group receives a sham (fake) procedure. This means that a small needle prick will be done, but no injection will be given. - For each participant, the first visit of Part A will be 6 months after they receive OA treatment. - Part A will have up to 6 clinic visits and 2 phone calls and last up to 1 year. - During Part B, both groups of participants will receive 80 mg of salanersen once a year. - Part B will have up to 12 clinic visits and 14 phone calls and last up to 4 years. - In total, participants will be in the study for up to 5 and a half years.
