There are about 7997 clinical studies being (or have been) conducted in Japan. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The main objective of the study is to assess the effect of treprostinil palmitil inhalation powder (TPIP) compared with placebo on pulmonary vascular resistance.
Study B7841007 is an open-label extension study to assess the long-term safety, tolerability, and efficacy of prophylaxis treatment with marstacimab in participants who did not require "Early Termination" from the Phase 3 Study B7841005 and from the Phase 3 Study B7841008. Study B7841005: approximately 145 adolescent and adult participants 12 to <75 years of age with severe hemophilia A or moderately severe to severe hemophilia B (defined as FVIII activity <1% or FIX activity ≤2%, respectively) with or without inhibitors are expected to be enrolled in Study B7841005 during which they will receive prophylaxis (defined as treatment by SC injection of marstacimab). Study B7841008: this is an ongoing Phase 3, open-label study in pediatric participants <18 years of age with severe hemophilia A (FVIII Coagulation Factor Activity <1%) or moderately severe to severe hemophilia B (FIX Coagulation Factor Activity ≤2%). A sequential approach will be used in enrolling at least 100 pediatric participants, at least 20 of which will be aged ≥12 to <18 years and at least 80 participants will be aged ≥1 to <12 years. At the start of study B7841008, the dosing and data available in adolescent and adult participants in Study B7841005 supported the initiation of B7841008 study in participants aged ≥12 to <18 years. Subsequently, additional safety and efficacy data from adolescent participants in Study B7841005 became available for benefit/risk assessment in support of dosing participants aged ≥6 to <12 years. Based on the positive benefit/risk assessment conducted by both internal Pfizer review and eDMC review, dosing of the ≥6 to <12 years age group was initiated in June 2023 in B7841008 Study. Data from participants ≥6 years from B7841008 Study and Study B7841005 will support the dosing of participants aged ≥1 to <6 years. All participants will be provided the prefilled pen (PFP) for administration of marstacimab in the study. Use of the prefilled syringe (PFS) will be permitted at the investigator's discretion for those participants who have difficulty with administration of the PFP. Additionally, participants will be provided the PFS for use in this study in countries where the PFS is anticipated to be the only presentation available commercially. An optional, open-label, single arm, substudy using the PFP was completed in the first 23 participants rolled over from Study B7841005 who agreed to participate in the substudy.
The purpose of this protocol is to provide continued treatment access and safety follow-up for eligible participants who continue to derive a benefit from study intervention in the Pfizer sponsored lorlatinib parent studies that will be closed. Additional follow-up safety data collection will permit further characterization of the safety profile of lorlatinib in participants continuing to receive study intervention
Hidradenitis suppurativa (HS) is a chronic and often painful inflammatory skin disease which includes the forming of lumps, abscesses and scars in areas of the skin such as under the breasts, under armpits, inner thighs, groin and buttocks. Despite the clinical benefit anti-tumor necrosis factor (TNF) therapy offers to patients with HS, there remains a significant unmet medical need for patients who fail to achieve adequate benefit with anti-TNF therapy. This study will compare lutikizumab (ABT-981) versus placebo for the treatment of adult participants with moderate to severe HS who have failed anti-TNF therapy. Lutikizumab (ABT-981) is an investigational drug being developed for the treatment of HS. In the Main Study, participants will be put in 1 of 4 groups, called treatment arms. There is a 1 in 4 chance that participants will be assigned to placebo. Around 160 adult participants with moderate to severe HS who have failed anti-TNF therapy will be enrolled in the study at approximately 50 sites worldwide. In the Sub-study, participants will be put in 1 of 2 groups, called treatment arms. Both arms will receive treatment at different dosing intervals. Around 40 adult participants with moderate to severe HS who are naïve to biologic therapy will be enrolled in the study at certain sites. In the Main Study, participants will receive subcutaneous injections of lutikizumab (ABT-981) or placebo every week for 16 weeks. In the Sub-study, participants will receive subcutaneous injections of lutikizumab (ABT-981) every week for the first 15 weeks, then either every week or every other week for 36 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires and diaries.
The purpose of this study is to evaluate the efficacy and safety of IV antifrolumab in adult patients with Active Proliferative Lupus Nephritis
This study will test how well a new medicine called concizumab works for participants who have haemophilia A or B with or without inhibitors. The purpose is to show that concizumab can prevent bleeds and is safe to use. Participants will have to inject the study medicine every day under the skin with a pen-injector. The study will last for at least 2 years and up to about 4 years. The length of time the participant will be in the study depends on if the study medicine will be available for purchase in their country.
This study is researching a clinical treatment combination with two experimental drugs called pozelimab and cemdisiran. The study is focused on patients with paroxysmal nocturnal hemoglobinuria (PNH). The aim of the study is to see how safe and effective the pozelimab + cemdisiran combination is for patients with PNH and how the combination compares with 2 existing treatments, one called ravulizumab and the other called eculizumab. The pozelimab + cemdisiran combination may be referred to as "study drugs". Ravulizumab and eculizumab may also be called the "comparator drug". The study is looking at several research questions, including: - How effective is the pozelimab + cemdisiran combination compared to ravulizumab? - How effective is pozelimab + cemdisiran combination compared to eculizumab? - What side effects may happen from taking the study drugs? - How much study drugs are in the blood at different times? - Whether the body makes antibodies against the study drugs (which could make the study drugs less effective or could lead to side effects)
This study is being done to see if tucatinib works better than placebo when given with other drugs to treat participants with HER2-positive breast cancer. A placebo is a pill that looks the same as tucatinib but has no medicine in it. This study will also test what side effects happen when participants take this combination of drugs. A side effect is anything a drug does to the body besides treating your disease. Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic). In this study, all participants will get either tucatinib or placebo. Participants will be assigned randomly to a group. This is a blinded study, so patients and their doctors will not know which group a participant is in. All participants will also get trastuzumab and pertuzumab. These are 2 drugs used to treat this type of cancer.
This research study is studying a new compound, AZD8205, as a possible treatment for advanced or metastatic solid tumours alone or in combination with anti-cancer agents
The administration of Janus kinase (JAK) inhibitors as well as biological disease-modifying anti-rheumatic drugs has dramatically improved even the clinical outcomes in rheumatoid arthritis (RA) patients with inadequate response to methotrexate (MTX). Upadacitinib is a selective JAK1 inhibitor to be approved for use in RA. Nearly half of patients added JAK inhibitors including upadacitinib can achieve clinical remission in RA patients with inadequate response to MTX. As the next step, it is the great issue whether disease activity can be maintained in good condition even if MTX is discontinued after achieving clinical remission in patients treated with the combination of JAK inhibitors and MTX. Thus, it is desirable to investigate the maintenance of clinical non-relapse after discontinuation of MTX in RA patients with clinical remission during treatment with upadacitinib plus MTX. In this study, we will evaluate the proportion of patients who maintained nonclinical relapse after discontinuation of MTX in patients with RA who achieved clinical remission after treatment with upadacitinib plus MTX. We will also use musculoskeletal ultrasound (MSUS) assessments to determine whether discontinuation of MTX can be maintained nonclinical relapse in RA patients achieving clinical remission.
