A Long-Term Extension Study of Vedolizumab in Children and Teenagers With Ulcerative Colitis (UC) or Crohn's Disease (CD)

The main aim of this study is to learn about medical problems (adverse events) if vedolizumab subcutaneously (SC) is given to a child or teenager with UC or CD for a long time. Other aims are to understand if the long time use of vedolizumab SC has an impact on the time period until hospital visits because of bowel swelling (inflammation) are needed and has an impact on the quality of life of children and teenagers who received vedolizumab SC. In this study, participants who responded well to the treatment with vedolizumab SC in the parent study (VedolizumabSC-3003 \[NCT06100289\]) will continue to be treated with vedolizumab SC. Participants who did not respond well to the treatment with vedolizumab SC in the parent study or who received corticosteroids in the last 4 weeks of the parent study will not receive vedolizumab SC in this study but will be followed for up to 2 years after the last treatment with vedolizumab SC in the parent study. During the study, participants will visit their study clinic several times.

A Study of TAK-360 in Adults With Narcolepsy Without Cataplexy (NT2)

Narcolepsy without cataplexy or Narcolepsy Type 2 (NT2) is a lifelong condition that makes people very sleepy during the day, regardless of how much sleep they get at night. People with NT2 may fall asleep suddenly, have trouble staying awake during the day, or may not be able to sleep well at night. They may have difficulty thinking clearly, paying attention, or remembering things, during the day. These symptoms can make daily activities like driving, working, or caring for their families challenging, impacting their quality of life. Orexin is a chemical made in the brain that helps keep a person awake and alert. TAK-360 acts like orexin. Previous studies have shown that medicines that act like orexin may keep people awake. The main aim of this study is to learn how safe TAK-360 is and how well adults with NT2 tolerate it. Researchers also want to find out if TAK-360 can help people with NT2 stay awake and determine the right dosage needed to do that. Participants will be randomly (by chance, like drawing names from a hat) assigned to get either TAK-360 or placebo in the treatment period. The placebo is a pill that looks just like TAK-360 but does not have any medicine in it. Using a placebo helps researchers learn about the real effect of the treatment.

A Study of Vedolizumab in Adults With Ulcerative Colitis (UC) or Crohn's Disease (CD) in the Community Setting

Ulcerative Colitis (UC) and Crohn's Disease (CD) are long-term conditions in the gut that can cause diarrhea, swelling (inflammation), bleeding from the anus, and belly pain. The main aim of this study is to check for how many participants with UC and CD signs and symptoms disappear after 3.5 months (14 weeks) of treatment with Vedolizumab (this is called remission). Participants will be treated with Vedolizumab for approximately 1 year (50 weeks). During the first 1.5 months (6 weeks), participants will receive Vedolizumab as an infusion in the vein (called intravenously). After this, participants will receive Vedolizumab as an injection under the skin (called subcutaneously) for the rest of the treatment. Participants for whom the treatment does not seem to work well after 3.5 months (14 weeks) will stop treatment with Vedolizumab and can change to another treatment and also there will be additional required visits at 6 months (26 weeks) and at 1 year (52 weeks). All participants will be checked again 4.5 months (18 weeks) after their last treatment with Vedolizumab. During the study, participants will visit their study clinic several times.

A Study to Better Understand the Diagnosis and Treatment of Polycythaemia Vera

PV is a rare, long-term blood cancer that causes the body to make too many blood cells. This can make the blood thicker than normal and the risk of blood clots higher. People with PV often experience symptoms that can affect their daily lives. Understanding how doctors diagnose and treat PV in everyday medical practice in a certain country can help find the differences in knowledge, diagnosis, and treatment of PV across countries. This study will not review or collect data from actual people with PV. It will collect information on the diagnosis and treatment of PV using a standard set of questions on and examples of fictional (unreal) people with PV. This is called clinical vignette. The study will ask doctors from several countries to complete this survey. The main aim of this study is to better understand how well doctors know about and diagnose PV and how they treat PV in certain countries. Other aims are to better understand how PV is managed and treated in everyday medical practice across countries. This includes which treatment people with PV receive once they are diagnosed and how access to medicines and healthcare services and other factors affects a doctor's treatment decisions for PV.

A Study of Secondary Immunodeficiencies in Adults With Blood Cancers in Kazakhstan Who Have a Weakened Immune System (K-SIDE Study)

Some people with blood cancers (hematologic malignancies) develop a weakened immune system because of their condition or the medicines used to treat it. This is called a secondary immunodeficiency or SID. A weakened immune system can make it harder for the body to fight infections. SIDs make participants more likely to have serious infections, need treatment at a hospital, and need longer treatment periods with antibiotics. SIDs are common but often overlooked in people with blood cancers in Kazakhstan. Currently, Kazakhstan does not have national guidelines for diagnosing and managing SIDs, which leads to differences in how people are assessed and treated across healthcare settings. The main aim of this study is to understand how common SIDs are in adults with blood cancers in Kazakhstan, which people are most affected and how often related health problems such as infections happen. Other aims are to learn more about SIDs in Kazakhstan: how SIDs are treated, how they affect a person's health and daily life (clinical burden) and how certain factors (such as age, health condition, treatment, type and stage of the blood cancer) may influence SIDs. This study will not collect any new data. It will use existing health records and data from Kazakhstan's national oncology registry.

A Study of Rusfertide in Japanese Adults With Polycythemia Vera

Polycythemia vera (PV) is a rare blood cancer in which the body makes too many red blood cells. This can make the blood thicker and may increase the risk of serious health problems such as blood clots. Many people with PV need regular phlebotomy, which is a procedure to remove blood, to help keep their hematocrit level under control. Hematocrit is the proportion of red blood cells in the blood. The main aim of this study is to evaluate whether rusfertide helps Japanese participants with PV keep their hematocrit under control and avoid the need for phlebotomy. All participants in this study will receive rusfertide. This study is open-label, which means both the participants and the study team will know what treatment is being given. Participants will be followed for up to about 244 weeks, including a screening period, a 52-week initial treatment period, a long-term extension period, and a 4-week safety follow-up period.

A Study in Children and, Adults With Congenital Thrombotic Thrombocytopenic Purpura (cTTP) Treated With Adzynma

Congenital thrombotic thrombocytopenic purpura (cTTP) is a rare blood disorder that some people are born with. It is caused by a problem in a gene passed down from parents to children, which affects the body's ability to produce a enzyme called ADAMTS13. This enzyme helps to cut down a larger form of protein called von Willebrand Factor (VWF). People with cTTP have low levels of ADAMTS13. Without ADAMTS13, large forms of vWF build up and cause blood clots in small blood vessels. These clots can block blood flow to vital organs, causing serious health problems. Adzynma is a human ADAMTS13 protein made in the laboratory. It works the same way as natural ADAMTS13 does and may provide higher levels of ADAMTS13. The main aim of this study is to learn more about the risk of children and adults with cTTP treated with Adzynma developing antibodies that prevent Adzynma from working properly (called neutralizing antibodies) within 6 months after the first treatment and to understand the risk of allergic reactions within 7 days of the first treatment with Adzynma. Other aims are to better understand how safe treatment with Adzynma is over a longer period of time (called long-term safety) in children and adults with cTTP and to gather information about pregnancies and babies of women who have received Adzynma while pregnant. Only data already available in the medical records of the people who received Adzynma for the treatment of cTTP in normal clinical practice will be reviewed and collected during this study.

A Study to Compare Elritercept to Placebo in Adults With Myelofibrosis and Anemia Who Are Taking Ruxolitinib

The main aim of this study is to find out how well elritercept works to improve anemia in participants with myelofibrosis (MF) who are taking ruxolitinib when compared to placebo. Other aims are to learn how elritercept improves anemia compared to placebo; to learn if elritercept reduces tiredness, improves symptoms related to MF, and helps participants do physical activities more easily. The study also aims to find out how elritercept affects the bone marrow, the spleen, and whether participants develop antibodies to the study drug. The study will also check how safe elritercept is compared to placebo, and if elritercept stays safe over a long period of time. Participants will receive study treatment for at least 9 months (36 weeks). After this period, participants who received placebo will have the option to switch to elritercept.

A Study of Mezagitamab in Adults With Late Antibody-Mediated Rejection (AMR) After a Kidney Transplant

Antibody-mediated rejection (AMR) is a major cause of worsening kidney function after a kidney transplant (kidney allograft dysfunction) and can lead to kidney failure. AMR happens when the kidney recipient's immune system makes antibodies that attack the donor kidney. Antibodies are proteins made by the immune system to recognize foreign cells. Over time, this attack can damage kidney tissue and cause the transplant to fail. Because AMR can be serious, there is a need for treatments that are safe, work well, and are supported by good evidence. The main aim of this study is to find out how safe mezagitamab is and how well adults with AMR tolerate it compared with placebo. A placebo looks like medicine but has no active ingredients. The study will also look at whether mezagitamab helps to control inflammation in the transplanted kidney and helps keep kidney function stable, compared with placebo. Participants will be placed by chance in 1 of the 3 treatment groups in equal numbers. Two groups will receive mezagitamab in two different doses. One group will receive placebo. This means that out of every 3 participants, 2 will receive mezagitamab and 1 will receive placebo. During the study, participants will visit their study clinic several times.

A Study of Zasocitinib in Adults With Nonsegmental Vitiligo

Vitiligo is a long-term autoimmune condition that causes the skin to lose its color. The body's germ-fighting system (immune system) mistakenly attacks the skin cells (melanocytes) which produce the pigment that gives the skin color (melanin). This leads to the formation of patches of skin with less or no pigment (depigmentation). These patches can occur anywhere on the body. In the nonsegmental form of vitiligo, similar patches occur on both sides of the body (symmetrical patches). The main aim of this study is to learn how safe zasocitinib is, how well it works and how well it is tolerated by adults with nonsegmental vitiligo. The participants will receive the study treatment (either zasocitinib or placebo) for up to 1 year (52 weeks). The placebo looks like the zasocitinib capsule but does not have any medicine in it. Participants who receive placebo at the beginning will change to zasocitinib after about 6 months. During the study, participants will visit their study clinic 11 times.

A Study of Mezagitamab in Adults With Kidney Condition Called IgA Nephropathy

Immunoglobulin A nephropathy (IgAN) is a kidney condition. It happens when the body's immune system creates groups of proteins (called immune complexes) that build-up in the kidneys causing swelling (inflammation). Over time, this inflammation may lead to kidney damage and cause the kidneys to no longer work properly. The main aim of this study is to check how well mezagitamab changes protein levels in the urine (proteinuria) compared to placebo in adults with primary IgAN. A placebo looks like medicine but doesn't have any active ingredients in it. Other aims are to check how safe mezagitamab is and how well participants with primary IgAN can tolerate it compared to placebo, and to find out if and how well mezagitamab continues to maintain kidney function over the long term compared to placebo. Participants will be placed in 1 of the 2 treatment groups; the main group and the open-label group. In the main group, participants will be placed by chance in either the mezagitamab or placebo treatment group at a 2:1 ratio. This means that out of 3 participants, 2 will receive mezagitamab and 1 will receive placebo. Participants can be in the study for 2 years (104 weeks). Participants will receive study treatment for about half a year (22 weeks) and then be observed for the remainder of the study (about 1.5 years). During observation, participants will continue to have check-ups about every month. In the open-label group, a small number of participants who either have lower levels of protein in their urine or have kidneys that do not filter the blood well, will receive mezagitamab treatment. This will include participants who have previously received mezagitamab in another study, TAK-079-1006. Every participant will receive mezagitamab in the same way as those in the main group receiving mezagitamab. During the study, participants will visit their study clinic several times.

A Study on the Safety of TAK-279 and Whether it Can Reduce Inflammation in the Bowel of Participants With Moderately to Severely Active Crohn's Disease

Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. The purpose of this study is to evaluate the efficacy and safety of TAK-279 versus placebo in participants with moderately to severely active Crohn's disease (CD). The main aim of this study is to learn if the 3 different doses of TAK-279 reduce bowel inflammation and ulcers in the bowel compared to the placebo after 12 weeks of treatment. Another aim is to compare any medical problems that participants have when they take TAK-279 or placebo and how well the participants tolerate medical problems. An endoscopy will be used to check the bowel for inflammation. The participants will be treated with TAK-279 for 52 weeks (1 year). During the study, participants will visit their study clinic 15 times.

A Study of TAK-188 in Adults With Advanced or Spreading Solid Tumors

TAK-188 is a new medicine that targets a protein called CCR8, which is found on the surface of certain cells (Tregs) inside tumors. These cells can weaken the body's ability to fight cancer. TAK-188 may help to remove these Tregs. Removing these Tregs may allow more cancer-fighting cells (CD8+ T cells) to attack the tumor and potentially stop tumors from growing. In this study, researchers want to learn if TAK-188 can help the body's immune system better fight cancer in adults with advanced cancers which have not gotten better with regular treatments. The main aims of this study are to check if TAK-188 is safe in adults with advanced or spreading (metastatic) solid tumors, if participants tolerate the treatment with TAK-188 and to learn if TAK-188 works well in adults with certain advanced cancers after their previous treatments didn't work. Participants may receive TAK-188 for up to 1 year. Their health will be monitored after the treatment has ended for up to another year.

A Study of TAK-360 in People With Narcolepsy or Idiopathic Hypersomnia

Central hypersomnia conditions are a group of sleeping disorders where the brain has trouble keeping a person awake during the day (called excessive daytime sleepiness or EDS). These conditions usually include narcolepsy (type 1 and 2) and idiopathic hypersomnia (IH). Narcolepsy type 1 (NT1) includes sudden muscle weakness while you stay awake, called cataplexy, often triggered by strong emotions. Narcolepsy type 2 (NT2) does not include cataplexy. People with narcolepsy typically feel refreshed by short naps. People with IH feel extremely sleepy during the day, and do not feel refreshed by sleep. Waking up from sleep is difficult. This is common in the morning and also when waking up from long naps. The study wants to learn about TAK-360 when taken over a long time period; this is called a long-term extension or LTE study. The main aim of this LTE study is to find out how well participants with NT1, NT2, and IH tolerate TAK-360 over a longer period (long-term tolerability) and to learn how safe TAK-360 is when given over a longer period of time (long-term safety). Participants who completed one of the TAK-360 parent studies can join this study if they meet the study rules. Parent studies include TAK-360-2001(NCT06952699), TAK-360-2002 (NCT06812078), or other TAK-360 studies that evaluate the TAK-360 medicine. All participants will receive TAK-360 in this study. They will either receive the same dose as they did in the parent study, or the closest dose available in this LTE study. Participants who received placebo (the placebo looks just like TAK-360 but does not have any medicine in it) in their parent study will receive one of the TAK-360 doses available in this study. Placebo will only be used to not reveal the dose of TAK-360 from parent studies to investigator, participants, and sponsor. Sponsor, investigators and participants will not know which TAK-360 dose was used in the LTE study as long as the parent study is ongoing. The participants will have to visit the clinic multiple times during this study.

A Study of Fruquintinib in Adults With Metastatic Colorectal Cancer in Poland

Metastatic colorectal cancer or mCRC is a cancer that starts in the parts of the large intestine (the colon or rectum) and has already spread to other parts of the body. This cancer can be hard to treat because it can behave differently from one person to another. Over time, treatments may stop working, and side effects can build up. In later treatment stages, there are only a few standard medicine options available. Because of this, studies often look at both how long people live and how treatment affects quality of life. The main aim of this study is to see how long adults in Poland with mCRC live without their cancer getting worse (progression-free survival or PFS) when they receive fruquintinib after at least two previous treatments. Fruquintinib (TAK 113) is a medicine taken by mouth that is designed to slow tumor growth. Other aim is to find out how long adults in Poland with mCRC live while being treated with fruquintinib (overall survival or OS). The study also wants to record how fruquintinib is used in routine care in adults with mCRC in Poland (for example when treatment starts, changes in doses, and how long treatment continues). Another aim is to learn about people with mCRC, such as their medical history and past treatment as well as their quality of life while they are in the study. The study will look at data already existing in the participants' medical charts.

A Study of Mezagitamab in Adults With Chronic Primary Immune Thrombocytopenia

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).

They also have longer bleeding compared to people without AHA. The main aim of the study is to learn how safe OBIZUR is in adults with AHA. Other aims are to see how effective OBIZUR is to control bleeding and how treatment is used in a routine clinical practice setting. The treatment of the participants will be determined by the treating physicians. During the study, data already existing in the participants' medical record and new data will be collected.

A Study of TAK-505 in Adults With Solid Tumors

Solid tumors occur when cells in an organ or tissue (for example in the lung or liver) start growing out of control (cancer) and form a lump or mass of cells. These solid cancers may grow very far in the general area where they started (called locally advanced) or may spread to other parts of the body (called metastatic), and doctors may not always be able to completely remove them with surgery (called unresectable). This study is a first in human (or FIH) study, which means that this is the first time that the medicine, TAK-505, is given to a smaller group of adults with solid tumors of certain cancer types, such as stomach cancer (gastric adenocarcinoma), cancer of the large bowel (colorectal cancer or CRC), lung cancer (non-small lung cell cancer or NSCLC) and cancer in the mouth, throat or voice box (head and neck squamous cell carcinoma or HNSCC). The main aims of this study are to learn how safe TAK-505 is, how well it works, how well adults with solid tumors tolerate it and to find the dose of TAK-505 that works best with the least side effects. Other aims are to learn how TAK-505 moves through the body (pharmacokinetics (PK)), if it can shrink or slow cancer (preliminary antitumor activity) and to find out if it causes the body's defense system to react to it (immunogenicity).

Continuation Study of Zasocitinib in Adults With Psoriatic Arthritis

Psoriatic arthritis (PsA) is a long-term inflammatory disease that affects the joints and skin. The purpose of this study is to check how safe zasocitinib is, how well it is tolerated and how well it works in adults with PsA over a longer period of time. Adults who completed the 1-year (52-week) treatment period in one of the parent studies (TAK-279-PsA-3001 \[NCT06671483\] or TAK-279-PsA-3002 \[NCT06671496\]) may be able to join this continuation study (also called long-term extension or LTE study). All participants in this continuation study, will receive zasocitinib (lower or higher dose), once a day (QD). Each participant can be in this study for approximately 2 years (108 weeks). This includes a treatment period of up to 2 years (104 weeks) and a 1-month (4-week) follow-up period to monitor a participant's health.
