NCT06810505
Migraine is a disease that most often causes moderate to severe headache on one side of the head. A migraine attack is a headache that may be accompanied by throbbing, nausea, vomiting, sensitivity to light and sound, or other symptoms. The goals of the study are to evaluate adverse events and how well treatment of atogepant works compared to placebo (looks like the study treatment but contains no medicine) in preventing chronic migraine in participants between 12 and 17 years of age. Atogepant is a medicine currently approved in the United States and Europe for the preventive treatment of migraine in adult patients with migraine and is being studied for the preventative treatment of chronic migraine in participants between the ages of 12 and 17 years. Participants will be randomly assigned to one of the 2 groups to be treated with either atogepant or placebo. This study is double-blinded, which means that neither the patients nor the study doctors know who is given which study treatment. Approximately 420 participants 12 to 17 years of age with chronic migraine will be enrolled at approximately 70 sites across the world. Participants will receive oral tablets of atogepant or placebo once daily for 12 weeks and will be followed for 4 weeks. Participants will attend regular visits during the study at a hospital or clinic and the effects of treatment will be checked by completion of a daily diary, medical assessments, blood tests, checking for side effects, and completing questionnaires.
NCT06064097
This phase II trial tests effects of nivolumab in combination with chemotherapy drugs prior to radiation therapy patients with nasopharyngeal carcinoma (NPC). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Researchers want to find out what effects, good and/or bad, adding nivolumab to chemotherapy has on patients with newly diagnosed NPC. In addition, they want to find out if children with NPC may be treated with less radiation therapy and whether this decreases the side effects of therapy.
NCT05554380
This phase II ComboMATCH treatment trial tests the usual treatment of chemotherapy (paclitaxel) plus ipatasertib in patients with solid tumor cancers that that cannot be removed by surgery (unresectable), has spread to nearby tissue or lymph nodes (locally advanced) or from where it first started (primary site) to other places in the body (metastatic), and has PTEN and AKT genetic changes. Chemotherapy drugs, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Targeted therapy, such as Ipatasertib, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The addition of ipatasertib to paclitaxel in solid tumors with PTEN and AKT genetic changes could increase the percentage of tumors that shrink as well as lengthen the time that the tumors remain stable (without progression). Researchers hope to learn if paclitaxel plus ipatasertib will shrink this type of cancer or stop its growth.
NCT03712605
This phase III trial studies how well pembrolizumab works compared to standard of care observation in treating patients with stage I-III Merkel cell cancer that has been completely removed by surgery (resected). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
NCT06315023
The purpose of this post-market surveillance study will be to evaluate the real-world use of the DETOUR System in treated patients with symptomatic femoropopliteal lesions from 200 mm to 460 mm in length with chronic total occlusions (100 mm to 425 mm) or diffuse stenosis \> 70% who may be considered suboptimal candidates for surgical or alternative endovascular treatments.
NCT07218029
Researchers are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse. Sotatercept is a study medicine designed to treat PAH. It is a targeted therapy, which is a treatment that works on certain proteins that play a role in causing PAH. This is a long-term follow-up (LTFU) study. People who took part in certain other studies testing sotatercept for PAH may be able to join this study. The goal of this study is to learn about the long-term safety of sotatercept and if people tolerate it when taken with standard PAH treatment over a longer period of time.
NCT06872892
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.
NCT07089888
The primary objective of this study is to evaluate the efficacy of dotinurad in lowering serum uric acid (sUA) at Week 24 compared with allopurinol in adult participants with tophaceous gout.
NCT05638295
This phase II ComboMATCH treatment trial tests how well AMG 510 (sotorasib) with or without panitumumab works in treating patients with KRAS G12C mutant solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Sotorasib is in a class of medications called KRAS inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells. Panitumumab is in a class of medications called monoclonal antibodies. It works by slowing or stopping the growth of cancer cells. Giving combination panitumumab and sotorasib may kill more tumor cells in patients with advanced solid tumors with KRAS G12C mutation.
NCT05063552
This phase II/III compares the standard therapy (chemotherapy plus cetuximab) versus adding bevacizumab to standard chemotherapy, versus combination of just bevacizumab and atezolizumab in treating patients with head and neck cancer that has spread to other places in the body (metastatic or advanced stage) or has come back after prior treatment (recurrent). Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Cisplatin and carboplatin are in a class of chemotherapy medications known as platinum-containing compounds. They work by killing, stopping, or slowing the growth of cancer cells. Docetaxel is in a class of chemotherapy medications called taxanes. It stops cancer cells from growing and dividing and may kill them. The addition of bevacizumab to standard chemotherapy or combination therapy with bevacizumab and atezolizumab may be better than standard chemotherapy plus cetuximab in treating patients with recurrent/metastatic head and neck cancers.

NCT07161037
The purpose of the study is to evaluate the effect of VX-407 on height-adjusted total kidney volume (htTKV), safety, tolerability, and pharmacokinetics (PK) of VX-407.
NCT06563895
Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque-like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age. Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN. Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs. This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.
NCT06721013
The purpose of the phase 1 part of this study is to evaluate how well pirtobrutinib is tolerated and what side effects may occur. The phase 2 part of the study will further investigate efficacy and safety of multiple pirtobrutinib dosages versus placebo. The study drug will be administered orally in participants with Primary Immune Thrombocytopenia (ITP). Blood tests will be performed to check how much pirtobrutinib gets into the bloodstream and how long it takes the body to eliminate it. The study will last up to approximately 16 weeks for phase 1 dose-escalation and 28 weeks for phase 2 dose-optimization, excluding screening.
NCT06873945
The purpose of the study is to learn about the safety and effects of the study medicine (called ritlecitinib) for the treatment of alopecia areata. Alopecia areata is a disease that causes hair loss on the scalp, face, and areas of the body. Ritlecitinib is approved in many countries at a dose of 50 mg (milligram) taken by mouth once a day for the treatment of patients 12 years and older with severe alopecia areata. This study will look at both the 50 mg dose and a 100 mg dose. This study is seeking participants who: * Are 12 years of age or older * Have a diagnosis of alopecia areata * Have lost 50% or more of the hair on their scalp * Do not have any other conditions that causes hair loss * Are willing to stop all other treatments that they may be taking for alopecia areata About 550 participants will take part in in this study. Participants will be chosen by chance, like drawing names out of a hat, to receive 1 of 2 different amounts of ritlecitinib (50 mg and 100 mg) taken by mouth once daily. The 2 doses of ritlecitinib in this study will be compared to each other and also to data from previous studies. This will help to see if the 100 mg dose of ritlecitinib is safe and effective. People will be in this study for about 13 months. During the study, participants will need to visit the study site up to 9 times. Participants will undergo various tests and procedures such as: * alopecia areata assessment, * physical examinations, * hearing tests, * blood tests, * x-ray, * ECG (electrocardiogram), * photographs of the scalp and eyes. Participants will also be asked to complete questionnaires about their alopecia areata.
NCT04929028
This phase II trial studies the side effects of chemotherapy and intensity modulated radiation therapy in treating patients with low-risk HIV-associated anal cancer, and nivolumab after standard of care chemotherapy and radiation therapy in treating patients with high-risk HIV-associated anal cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as mitomycin, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy with radiation therapy may kill more tumor cells. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nivolumab after standard of care chemotherapy and radiation therapy may help reduce the risk of the tumor coming back.
NCT06846281
The purpose of this Phase 3b study is to assess the efficacy, safety and tolerability of remibrutinib after switching from ocrelizumab and compared to continuous ocrelizumab treatment, in patients living with relapsing multiple sclerosis (plwRMS).
NCT02298959
This phase I trial studies the side effects and best dose of ziv-aflibercept when given together with pembrolizumab in treating patients with solid tumors that that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Ziv-afibercept works by decreasing blood and nutrient supply to the tumor, which may result in shrinking the tumor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving ziv-aflibercept together with pembrolizumab may be a better treatment for patients with advanced solid tumors.
NCT06979596
Researchers want to learn if MK-5684 (the study medicine) can treat breast cancer, ovarian cancer, and endometrial cancer. MK-5684, the study medicine, is designed to treat cancer by blocking the body from making steroid hormones. Researchers will compare MK-5684 to the standard treatments for each cancer type in this study. The goal of this study is to learn if people who receive MK-5684 live longer without the cancer growing or spreading compared to people who receive a standard treatment.
