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 purpose of the study is to evaluate the reactogenicity, safety, and immunogenicity of an investigational respiratory syncytial virus (RSV) vaccine, mRNA-1345, in pregnant women, and safety and immunogenicity in infants born to vaccinated mothers.
This is a multicenter, randomized, placebo- and active-controlled, parallel-group, 24-week trial to investigate the efficacy, safety, and tolerability of XXB750 in participants with HFrEF/HFmrEF.
The purpose of this randomized, double-blind, placebo-controlled, parallel group study is to determine the efficacy of frexalimab in delaying the disability progression and the safety up to approximately 51 months administration of study intervention compared to placebo in male and female participants with nrSPMS (aged 18 to 60 years at the time of enrollment). People diagnosed with nrSPMS are eligible for enrollment as long as they meet all the inclusion criteria and none of the exclusion criteria. Study details include: - This event-driven study will have variable duration ranging from approximately 27 to 51 months. - The study intervention duration will vary ranging from approximately 27 to 51 months. - The number of scheduled visits will be up to 27 (including 3 follow-up visits) with a visit frequency of every month for the first 6 months and then every 3 months.
The purpose of each study is to independently measure the annualized relapse rate (ARR) with administration of frexalimab compared to a daily oral dose of teriflunomide in male and female participants with relapsing forms of multiple sclerosis (aged 18 to 55 years at the time of enrollment). People diagnosed with relapsing forms of multiple sclerosis are eligible for enrollment as long as they meet all the inclusion criteria and none of the exclusion criteria. Study details include: - This event-driven study will have variable duration of approximately 40 months for the first participant being randomized and approximately 20 months for the last participant randomized. - The study intervention duration will vary ranging from approximately 20 to 40 months. - The assessment of scheduled visits will include 1 common end of study [EOS] visit and 3 follow-up visits) with a visit frequency of every 4 weeks for the first 6 months and then every 3 months.
The purpose of this study is to evaluate the efficacy and safety of repotrectinib and crizotinib in participants with locally advanced or metastatic TKI-naïve ROS1-positive non-small cell lung cancer (NSCLC).
The masseter muscle is one of the muscles in the lower face used for chewing. Prominence of the masseter muscle can appear as a widened and square lower face shape, which is an aesthetic concern for individuals who prefer a narrower and more ovoid lower face shape. Treatments are available for masseter muscle prominence (MMP), but researchers are looking for new non-surgical treatments. This study will assess adverse events and effectiveness of BOTOX in adult participants with MMP. BOTOX is being investigated for the treatment of MMP. Participants are placed in 1 of 4 groups, called treatment arms. Each group receives a different treatment. There is 1 in 5 chance that participants will be assigned to placebo. Around 250 adult participants with MMP will be enrolled in the study at approximately 20 sites in Japan. Participants will receive either BOTOX or Placebo administered as 6 intramuscular injections to each masseter muscle on Day 1. Participants who are eligible for retreatment will be given BOTOX on either Day 180, 210, 240, or 270 and will be followed until approximately Day 360. There may be a 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, facial photography, checking for side effects and completing questionnaires.
The purpose of this study is to assess the efficacy and safety of opevesostat plus hormone replacement therapy (HRT) compared to alternative abiraterone acetate or enzalutamide in participants with Metastatic Castration-resistant Prostate Cancer (mCRPC) previously treated with one next-generation hormonal agent (NHA). The primary study hypotheses are that opevesostat is superior to alternative abiraterone acetate or enzalutamide with respect to radiographic progression free survival (rPFS) per Prostate Cancer Working Group (PCWG) Modified Response Evaluation Criteria in Solid Tumors (RECIST 1.1) as assessed by Blinded Independent Central Review (BICR) and overall survival (OS), in androgen receptor ligand binding domain (AR LBD) mutation positive and negative participants.
This is a phase 3, randomized, open-label study of opevesostat compared to alternative abiraterone acetate or enzalutamide in participants with metastatic castration-resistant prostate cancer (mCRPC) with respect to overall survival (OS) and to radiographic progression-free survival (rPFS) per Prostate Cancer Working Group (PCWG) Modified Response Evaluation Criteria In Solid Tumors (RECIST 1.1) as assessed by blinded independent central review (BICR) in participants with mCRPC previously treated with next-generation hormonal agent (NHA) and taxane-based chemotherapy. It is hypothesized that opevesostat is superior with respect to OS and rPFS per PCWG Modified RECIST 1.1 as assessed by BICR in androgen receptor ligand binding domain (AR LBD) mutation-negative and -positive participants.
The goal of this study is to evaluate nemtabrutinib compared with investigator's choice of ibrutinib or acalabrutinib in participants with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who have not received any prior therapy. The primary hypotheses are that (1) nemtabrutinib is non-inferior to ibrutinib or acalabrutinib with respect to objective response rate (ORR) per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria 2018 by blinded independent central review (BICR) and (2) nemtabrutinib is superior to ibrutinib or acalabrutinib with respect to progression free survival (PFS) per iwCLL Criteria 2018 by BICR.
OLIGAMI trial is a multi-institutional, two-arm, open-label, randomized controlled phase III trial being conducted with the participation of 50 hospitals belonging to Japan Clinical Oncology Group. After the first registration, all patients will be performed in a 12-week, subtype-specific, systemic therapy consisting of CDK4/6 inhibitors with hormonal therapy for luminal BC, docetaxel with trastuzumab and pertuzumab for HER2-positive BC, chemotherapy with immune checkpoint inhibitors for triple-negativeBC expressing PD-L1, and olaparib for cases harboring BRCA mutations. For other triple-negative BC, chemotherapy will be administered. If this 12-week systemic therapy does not cause any progression or complete response, patients proceed to second registration for randomization; arm A continues same systemic therapy alone, and arm B performs MDT followed by same systemic therapy. The MDT will involve either RT or surgery, and RT will involve mainly SBRT and partly conventional RT.
