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.
This is an open-label, multi-center, single arm, Phase II study to evaluate the efficacy and safety of T-DXd for the treatment of unresectable and/or metastatic solid tumors harboring specific HER2 activating mutations regardless of tumor histology. The target population are patients who have progressed following prior treatment or who have no satisfactory alternative treatment options, including approved second line therapies in the specific tumor type. Pre-specified HER2 mutations will be locally assessed using NGS tests or alternative methods. Prior HER2 targeting therapy is permitted.
The purpose of this study is to evaluate the safety, tolerability, immunogenicity, pharmacokinetics, and pharmacodynamics of multiple-ascending intravenous (IV) doses of RO7126209 in participants with prodromal or mild to moderate Alzheimer's disease (AD), who are amyloid positive based on amyloid positron emission tomography (PET) scan.
Approximately 63 participants will be randomized to one of three doses to receive Recifercept either - Low Dose - Medium Dose - High Dose Participants will will attend the clinic at baseline and at Day 1, 4, 8, 15, 29 & then Month 2, 3 6, 9 & 12. Assessments include safety, blood sampling, physical examination, vital signs, anthropometric body measurements & patient/caregiver quality of life questionnaires Participants will received treatment with Recifercept for 12 months. All participants who complete the study and in the opinion of the investigator, continue to have a positive risk:benefit profile, will be offered to enroll into an open-label extension (OLE) study. A PK cohort will include 12 participants who will randomly receive a single dose of 3 mg/kg of Phase 2 study (process 1c) formulation and a single dose of 3 mg/kg of the proposed Phase 3 (process 2) study formulation in a cross over study. Dose of the cohort could be changed due to emerging safety and efficacy data in the study.
The purposes of this phase 3, double-blind, placebo-controlled clinical study are to evaluate the efficacy of V503 (9-valent human papillomavirus [9vHPV] vaccine) in preventing HPV-related anogenital persistent infection, and to evaluate the safety/tolerability of V503, in Japanese males who are 16 to 26 years of age. It is hypothesized that administration of a 3-dose regimen of V503 reduces the combined incidence of HPV 6/11/16/18-related anogenital persistent infection, as well as the combined incidence of HPV 31/33/45/52/58-related anogenital persistent infection, compared with placebo. The study includes a Base Study to assess efficacy and safety of V503, and an Extension Study. Participants who received placebo in the Base Study will be eligible to receive V503 vaccine on Day 1, Month 2, and Month 6 of the Extension Study. Participants who received less than 3 doses of V503 in the Base Study will be offered the opportunity to complete the 3-dose regimen in the Extension Study.
The purpose of this study is to compare pembrolizumab + adjuvant chemotherapy with placebo + adjuvant chemotherapy, with or without radiotherapy, with respect to disease-free survival (DFS) as assessed radiographically by the investigator or by histopathologic confirmation of suspected disease recurrence, and with respect to overall survival (OS). The primary hypotheses are that pembrolizumab + adjuvant chemotherapy is superior to placebo + adjuvant chemotherapy, with or without radiotherapy, with respect to DFS as assessed radiographically by the investigator or by histopathologic confirmation of suspected disease recurrence, and with respect to OS.
The purpose of this study is to evaluate the efficacy and safety of talquetamab in participants with relapsed or refractory multiple myeloma at the recommended Phase 2 dose(s) (RP2Ds) (Part 3).
This study was a prospective, uncontrolled, central registration system, multicenter, domestic observational study (special drug-use surveillance) to evaluate the safety of 52-week clinical treatment with Beovu kit for intravitreal injection in nAMD patients.
To evaluate the following items by PET examination in Japanese heathy adult male subjects who received single oral administration of TS-091 in an unblinded manner. 1. Relationship between plasma concentration and H3 receptor-occupancy of TS-091 2. Time course changes in H3 receptor-occupancy of TS-091
The study was designed to demonstrate the safety and efficacy of two dose concentrations of SAF312 eye drops (5 mg/mL and 15 mg/mL) in subjects with CICP persisting at least for 4 months after refractive or cataract surgery and chronicity confirmed during the observational period. The study also determined the optimal dose to carry forward for further development.
The purpose of the study is to evaluate the efficacy of bedaquiline (BDQ) compared with rifamycin when administered as part of a treatment regimen with clarithromycin (CAM) and ethambutol (EB) in adult participants with treatment-refractory Mycobacterium avium complex-lung disease (MAC-LD) at Week 24 for microbiological assessment in mycobacteria growth indicator tube (MGIT).
