Immediate Necrosectomy vs. Step-up Approach for Walled-off Necrosis

Pancreatic fluid collection is a late complication of severe acute pancreatitis. According to the revised Atlanta classification, walled-off necrosis (WON) is defined as an encapsulated collection of necrotic tissue that is observed after four weeks of the onset of acute pancreatitis. Infected WON is associated with high morbidity and mortality; therefore, an appropriate treatment, including antibiotics and drainage, is mandatory. With the development of endoscopic equipment, endoscopic ultrasonography (EUS)-guided drainage has become a first-line treatment modality for infected WON. For patients who are refractory to EUS-guided drainage, endoscopic necrosectomy (EN) is a treatment option to facilitate direct removal of infected necrotic tissue within the WON. However, due to potentially lethal adverse events of EN, such as bleeding, perforation, and peritonitis, EN is usually withheld for several days after EUS-guided drainage. This strategy is known as "the step-up approach." Recently, with the accumulated evidence supporting the safety of EN, especially with the use of a dedicated lumen-apposing metal stent, it has been reported that EN immediately after EUS-guided drainage can shorten the treatment duration without increasing adverse events. Given these lines of evidence, the investigators hypothesized that immediate EN following EUS-guided drainage of WON might shorten time to clinical success compared to the step-up approach. To examine this hypothesis, the investigators planned to conduct a multicenter randomized controlled trial comparing treatment duration between EN immediately after EUS-guided drainage versus the step-up approach in patients with symptomatic WON.

Study to Evaluate the Efficacy and Safety of K-877-ER and CSG452 in Participants With NASH With Liver Fibrosis

A Study of KK4277 in Healthy Volunteers and Patients With Systemic Lupus Erythematosus and Cutaneous Lupus Erythematosus

A Study of Daratumumab, Bortezomib, Lenalidomide and Dexamethasone (DVRd) Followed by Ciltacabtagene Autoleucel Versus Daratumumab, Bortezomib, Lenalidomide and Dexamethasone (DVRd) Followed by Autologous Stem Cell Transplant (ASCT) in Participants With Newly Diagnosed Multiple Myeloma

Multiple myeloma (MM) is a malignant plasma cell disorder characterized by the production of monoclonal immunoglobulin (Ig) proteins or protein fragments (M proteins) that have lost their function. JNJ-68284528 (ciltacabtagene autoleucel [cilta-cel]) is an autologous chimeric antigen receptor T cell (CAR-T) therapy that targets B-cell maturation antigen (BCMA) that is being evaluated to treat participants with multiple myeloma. The primary hypothesis is that in transplant-eligible participants with newly diagnosed multiple myeloma (NDMM), cilta-cel will significantly improve progression-free survival (PFS) and Sustained MRD-negative CR rate compared with Autologous Stem Cell Transplant (ASCT). Approximately 750 participants (375 per arm) will be randomly assigned in a 1:1 ratio into 2 arms.

A Study Evaluating the Efficacy and Safety of Afimetoran Compared With Placebo in Participants With Active Systemic Lupus Erythematosus (SLE)

Study of 177Lu-PSMA-617 In Metastatic Castrate-Resistant Prostate Cancer in Japan

This study is an open label, multicenter, single arm, phase II study to evaluate the efficacy, tolerability, safety, PK and dosimetry of 177Lu-PSMA-617 in participants with progressive PSMA-positive mCRPC in Japan. Furthermore, the safety, PK, and dosimetry of 68Ga-PSMA-11 (PSMA imaging agent) are also evaluated in this study. This study consists of two populations: 1. Post-taxane population: The post-taxane population will include men with PSMA-positive mCRPC who received at least one ARDT (for example enzalutamide, abiraterone etc.) and were previously treated with at least one, but no more than two taxane regimens. Participants treated with only 1 prior taxane regimen are eligible if the participant's physician deems the participants unsuitable to receive a second taxane regimen. 2. Pre-taxane population; The pre-taxane population will include men with PSMA-positive mCRPC who were previously treated with one ARDT as last treatment and have not been exposed to a taxane-containing regimen in the CRPC or HSPC settings and for whom it is considered appropriate to delay taxane-based chemotherapy. This is a 4-part study: Part 1 (a safety run-in part), Part 2 (post-taxane part), Part 3 (pre-taxane part) and Part 4 (expanded trial part). 1. Part 1 (safety run-in part) will confirm the tolerability and safety of recommended regimen, once every 6-weeks, 7.4 GBq of the 177Lu-PSMA-617. Minimum of 3 participants as 177Lu-PSMA-617 tolerability evaluable participants will be enrolled. Dosimetry and PK assessments of 177Lu-PSMA-617 are mandatory for participants enrolled in this part. 2. Part 2 (post-taxane part) will evaluate the efficacy, safety, PK and dosimetry of 177Lu-PSMA-617 plus BSC/BSoC, as well as safety, PK, and dosimetry of 68Ga-PSMA-11 in post-taxane participants with PSMA-positive mCRPC. 3. Part 3 (pre-taxane part) will evaluate the efficacy, safety, PK and dosimetry of 177Lu-PSMA-617, as well as safety, PK, and dosimetry of 68Ga-PSMA-11 in taxane naïve participants with PSMA-positive mCRPC 4. Part 4 (expanded trial part) will provide humanistic perspective access of study treatment (68Ga-PSMA-11 and 177Lu-PSMA-617) for the Japanese post-taxane participants with PSMA-positive mCRPC until marketed products are available in Japan. Additional safety and efficacy of 68Ga-PSMA-11 and of 177Lu-PSMA-617 will be evaluated. Additionally, PK and dose rate will be evaluated (PK is optional and dose rate is mandatory in Part 4). Approximately 50 eligible participants will be enrolled in Part 4 and approximately 10 evaluable participants PK data will be collected. This study will consist of 3 periods: screening period, treatment period, and long term follow up.
