Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation (CIC) in this 26-week phase 3 study. The study is randomized, double-blind, and placebo-controlled, involving multiple centers. It aims to compare three doses of tenapanor (5 mg, 25 mg, and 50 mg taken twice daily) against a placebo, with a focus on improving spontaneous bowel movements. Participants will first undergo a 2-week screening where their eligibility is assessed through medical history, physical exams, lab tests, ECG, and self-reported constipation symptoms using an electronic diary (eDiary). Eligible patients will then be randomly assigned to receive one of the three doses of tenapanor or placebo twice daily for 26 weeks. During this treatment period, patients will continue daily and weekly symptom reporting via the eDiary and attend regular safety visits at weeks 2, 4, 8, 12, 16, 20, and 26. After completing the 26-week treatment, patients enter a 4-week treatment-free safety follow-up period to monitor any adverse events. A final visit occurs at the end of this follow-up to assess safety. The main outcome measured is the durable complete spontaneous bowel movements response over 12 weeks. Overall, the study involves careful monitoring of symptoms, safety, and treatment effects over approximately 32 weeks.

Researchers are investigating sacituzumab tirumotecan (MK-2870) alone or combined with other treatments to treat certain gastrointestinal cancers. These include colorectal cancer that cannot be removed by surgery or has spread, advanced pancreatic ductal adenocarcinoma, and biliary tract cancer. The study aims to understand the safety and tolerability of sacituzumab tirumotecan and measure how many participants respond to the treatment by having their cancer shrink or disappear. Participants may receive sacituzumab tirumotecan by intravenous infusion alone or with other anticancer drugs such as fluorouracil (5-FU), leucovorin or levoleucovorin, cisplatin, and pembrolizumab. Rescue medications like diphenhydramine, H2 receptor antagonists, acetaminophen, dexamethasone, and a steroid mouthwash are given to prevent infusion reactions and oral side effects. Supportive care treatments for side effects, including antidiarrheal and antiemetic agents, are allowed throughout the study. During the study, researchers monitor participants for dose-limiting toxicities within about 4 weeks and track adverse events, treatment discontinuations, and tumor response over up to approximately 63 months. Assessments include safety evaluations and measuring cancer response using standardized criteria. This long-term follow-up helps evaluate both the effectiveness and safety of the treatments being studied.

Researchers are evaluating the effects of two different methods of giving pegloticase, a drug for uncontrolled gout, combined with methotrexate (MTX). This Phase 3 trial compares pegloticase given as an 18 mg injection under the skin every two weeks with pegloticase given as an 8 mg intravenous (IV) infusion every two weeks, both alongside weekly oral MTX. The main goal is to see which method better maintains normalized serum uric acid levels below 6 mg/dL for at least 80% of the time during the sixth month of treatment. Participants will be randomly assigned to receive pegloticase either by subcutaneous injection or intravenous infusion every two weeks, along with weekly oral doses of methotrexate. Both groups will be treated over several months while closely monitored. The study is double-blind, meaning neither participants nor researchers know which treatment is being given to maintain unbiased results. During the trial, participants will undergo regular assessments to monitor their serum uric acid levels and overall response to treatment, especially focusing on weeks 20 through 24 (Month 6). Safety and efficacy will be tracked throughout the study, including how well participants tolerate the treatments and any side effects. The study's main measure is the proportion of participants who achieve a sustained uric acid response during Month 6.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab as first-line treatments for patients with metastatic non-small cell lung cancer (mNSCLC) whose tumors have high PD-L1 expression. This Phase III, randomized, double-blind, and global study focuses on participants with stage IV mNSCLC who do not have certain genetic mutations or rearrangements and are eligible for systemic therapy. Participants receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two biological treatments given as monotherapy. Both groups will be monitored over time to assess treatment impact and safety. Throughout the study, participants undergo evaluations including tumor measurements by CT or MRI, performance status assessments, and organ function tests. Researchers will measure overall survival and progression-free survival for up to approximately five years. Tumor samples are collected before treatment for central testing, and participants’ health and treatment responses are closely followed during the trial period.

The purpose of this study is to assess the long-term safety and tolerability after an intravitreal injection (a shot of medicine into the eye) of JNJ-81201887 administered in parent clinical studies.

This research aims to collect long-term safety and effectiveness data for participants treated with ibrutinib, a medicine used for various blood cancers and conditions including Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, Mantle Cell Lymphoma, Follicular Lymphoma, Diffuse Large B-cell Lymphoma, Waldenstrom Macroglobulinemia, and Chronic Graft Versus Host Disease. It also provides ongoing access to ibrutinib for participants who have completed previous ibrutinib studies, continue treatment, and benefit from it. This is an open-label Phase 3b study without formal hypothesis testing. Participants will continue their current ibrutinib dosing regimen from the prior study, taken orally once daily as capsules in doses of 560 mg, 420 mg, 280 mg, or 140 mg, around the same time each day. Treatment continues until the investigator decides the participant no longer benefits due to disease progression or side effects, the participant withdraws, alternative ibrutinib access becomes available, or the study ends. Participants not able to access ibrutinib elsewhere can keep receiving the single-agent ibrutinib until all transition or stop treatment, or until the study is stopped. During the study, safety is monitored throughout and summarized, and effectiveness may be analyzed together with previous study data. The main outcome measured is the number of participants experiencing any adverse events within 30 days after the last dose or until starting another cancer treatment. Participants will undergo assessments including pregnancy testing and investigator evaluations to ensure ongoing benefit and safety. The study duration depends on when participants stop treatment or transition to other access.

Researchers are evaluating whether the drugs retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who are at high risk. This Phase 3 trial enrolls about 4,500 adults with MASLD identified by non-invasive tests indicating an increased likelihood of developing serious liver problems. The study aims to understand how these treatments might affect liver health over time compared to a placebo. Participants will be randomly assigned to receive either retatrutide, tirzepatide, or a placebo, all given by subcutaneous injection. The study will last approximately 224 weeks, during which participants may attend 25 to 30 clinic visits for monitoring and assessment. After the main study, eligible participants can join an optional 2-year extension where all will receive either retatrutide or tirzepatide regardless of their original group. Throughout the trial, participants’ liver function and disease progression will be closely monitored through various health assessments. Researchers will track the time to the first major adverse liver event as the main outcome. Safety and health status will be evaluated regularly during clinic visits, ensuring thorough observation over the long study period.

This trial investigates the safety and effectiveness of rilvegostomig combined with fluoropyrimidine and trastuzumab deruxtecan (T-DXd) compared to trastuzumab, chemotherapy, and pembrolizumab in adults with HER2-positive locally advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma whose tumors express PD-L1 with a combined positive score of 1 or higher. Additionally, rilvegostomig combined with trastuzumab and chemotherapy is studied separately to understand each component's contribution. This Phase 2, randomized, open-label, global study is conducted at 200-250 sites in about 25 countries. Participants are randomly assigned to one of three arms: Arm A receives rilvegostomig, fluoropyrimidine, and T-DXd; Arm B receives trastuzumab, chemotherapy, and pembrolizumab; Arm C receives rilvegostomig, trastuzumab, and chemotherapy. Treatments are administered mostly by intravenous infusion every three weeks, with capecitabine given orally twice daily. The study compares these treatment regimens to evaluate their effects on the cancer. Throughout the study, participants undergo assessments including tumor measurements, organ function tests, and heart function evaluation to ensure safety and monitor disease progression. The main outcomes measured are progression-free survival and overall survival for up to approximately six years. Researchers will also monitor adverse events and overall health status during and after treatment.

Researchers are evaluating the safety and effectiveness of Vagus Nerve Stimulation (VNS) Therapy as an additional treatment compared to no stimulation in people with treatment-resistant depression. This prospective, multi-center, randomized, controlled, blinded trial focuses on reducing depressive symptoms over 12 months using multiple depression rating scales. The study follows guidelines from the Centers for Medicare and Medicaid Services regarding evidence development for this treatment. Participants receive implantation of the VNS device, which delivers stimulation to the vagal nerve. After a minimum two-week period post-implantation, participants are randomly assigned to either active VNS treatment or no stimulation control, with outcomes observed for 12 months. Following this randomized phase, all participants enter an open-label extension where those in the control group receive active stimulation. Additional subjects may join this open-label study for up to five years to further assess long-term effects. Throughout the study, participants undergo regular assessments including the Montgomery Åsberg Depression Rating Scale (MADRS), WHO Disability Assessment Schedule, Health Outcome Scale, Clinical Global Impressions Scale, and Suicidality Tracking Scale. Researchers monitor response rates, remission times, duration of effects, and adverse events from implantation through 12 months. This comprehensive evaluation includes safety monitoring and functional outcome measures to understand the impact of VNS therapy on depression and related disabilities.

Researchers are evaluating azetukalner as a monotherapy in adults diagnosed with moderate-to-severe Major Depressive Disorder (MDD). This Phase 3, multicenter, randomized, double-blind, placebo-controlled study aims to assess the clinical efficacy, safety, and tolerability of azetukalner compared to placebo. Participants must be adults between 18 and 74 years old, experiencing a current major depressive episode confirmed by standard diagnostic criteria and lasting between 6 weeks and 24 months. Participants are randomly assigned to receive either azetukalner 20 mg or a placebo, both taken orally once daily with food (preferably with the evening meal) for 6 weeks. The study compares these two groups to determine the impact of azetukalner on depressive symptoms. The trial maintains double-blinding to ensure unbiased assessment of outcomes. During the study, participants undergo regular assessments including evaluations of depressive symptoms using the Hamilton Depression Rating Scale (HAMD-17) at baseline and at Week 6. Safety and tolerability are monitored throughout the treatment period. The total participation time corresponds to the 6-week treatment phase, during which symptom changes and adverse events are closely observed.
