Researchers are evaluating (Z)-endoxifen as a potential treatment for premenopausal women with estrogen receptor-positive (ER+) and HER2-negative breast cancer. This phase 2 open-label study includes two parts: a pharmacokinetic (PK) phase to understand how the body processes the drug and a treatment phase to assess the drug's effects on tumor growth. The study aims to see if (Z)-endoxifen can slow or stop tumor growth by measuring changes in a biomarker called Ki-67. Participants are premenopausal women who meet specific cancer and health criteria. Participants in the PK part will take (Z)-endoxifen capsules daily at varying doses (20 mg, 40 mg, or 80 mg). Some will also receive a monthly injection of goserelin, a drug that temporarily stops estrogen production in the ovaries. The treatment cohort will receive both (Z)-endoxifen and goserelin. Tumor tissue samples will be collected by breast biopsy after about 4 weeks to assess the Ki-67 biomarker. Participants showing tumor response may continue treatment for up to 24 weeks or until they undergo surgery. Throughout the study, participants will have blood draws to measure drug levels and tumor markers, breast biopsies, imaging scans, and safety assessments. The main outcomes include measuring (Z)-endoxifen levels after 4 weeks, the rate of Ki-67 reduction, and tumor response after 24 weeks. Study participation lasts up to 6 months, including treatment, surgery, and a follow-up visit one month after surgery.

Researchers are conducting a Phase 2, multicenter platform study to evaluate the safety and effectiveness of several investigational treatments for adults with moderately to severely active Inflammatory Bowel Disease (IBD), including Crohn's Disease and Ulcerative Colitis. The study focuses on assessing multiple experimental oral or injectable therapies to better understand their effects on these conditions. Participants will receive one of the study drugs, MT-501 or MT-201, as part of this evaluation. The study aims to gather data on how these treatments perform in terms of safety, how the body processes them (pharmacokinetics), and their biological effects (pharmacodynamics). Treatment effects will be measured over a period of up to 13 weeks. During the study, participants will be monitored for any side effects, serious adverse events, and laboratory test changes. Researchers will also assess the participants' clinical remission status and improvements seen through endoscopic evaluations at 12 to 13 weeks. The total involvement duration includes screening and treatment periods, with careful tracking of outcomes and safety throughout.

Researchers are evaluating the effectiveness, safety, and tolerability of two different doses of remibrutinib compared to a placebo in adults and adolescents with moderate to severe hidradenitis suppurativa (HS). This phase 3 study aims to determine how well remibrutinib works in treating this chronic skin condition characterized by painful abscesses and inflammatory nodules. The study lasts a total of 76 weeks and includes several phases: up to 4 weeks for screening, followed by a 16-week double-blind treatment period where participants receive either remibrutinib Dose A, Dose B, or a matching placebo. After this, there is a 52-week treatment period where all participants receive remibrutinib (Dose A or Dose B). Finally, a 4-week safety follow-up period occurs without treatment. Participants who stop treatment early are encouraged to stay in the study and complete the safety follow-up. During the study, participants will be regularly assessed for clinical response to treatment, focusing on the proportion achieving a 50% improvement in HS symptoms by week 16. Researchers will monitor safety and tolerability throughout the study, including during the follow-up period. Various evaluations such as physical exams and clinical assessments will be conducted to measure treatment effects and ensure participant safety over the entire 76-week duration.

Researchers are investigating how bone mineral density changes during long-term treatment with the relugolix combination tablet in premenopausal women aged 18 to 50 who have heavy menstrual bleeding caused by uterine fibroids or moderate to severe pain related to endometriosis. This Phase 3B, single-arm, open-label study aims to assess the safety and effects of up to 48 months (4 years) of continuous treatment, followed by a 1-year post-treatment follow-up period. Participants will receive a daily fixed-dose tablet containing relugolix 40 mg, estradiol 1 mg, and norethindrone acetate 0.5 mg. Bone mineral density will be monitored every 6 months using dual-energy X-ray absorptiometry during treatment. Some women who completed a prior related study may join for 3 years of treatment under this protocol. After treatment ends or if stopped early, participants will be followed for 1 year with bone density checks at 6 and 12 months. Women in the study will have regular physical, gynecological, and laboratory assessments to monitor health and treatment effects. Researchers will measure the percentage change from baseline in bone mineral density at the lumbar spine after 48 months of treatment. Safety and health status will be closely observed throughout the treatment and follow-up periods to understand the long-term impact of the relugolix combination tablet on bone health.

Researchers are evaluating the safety and effectiveness of fixed dose combinations of ensifentrine with two different doses of glycopyrrolate compared to placebo and each drug alone in adults with chronic obstructive pulmonary disease (COPD). This phase IIb study focuses on measuring lung function improvements using bronchodilator effects in people with COPD. Participants have a history of smoking and meet specific lung function criteria to be included. Participants will be randomly assigned to one of six groups: two combination treatments of ensifentrine (3 mg) with glycopyrrolate at either 21.25 or 42.5 mcg, each drug alone as monotherapy, or placebo. All treatments are given twice daily for 28 days using a standard jet nebulizer. The study includes 1 to 2 weeks of screening, 4 weeks of treatment, followed by 1 week of follow-up. During the study, participants will undergo lung function testing at baseline and on days 1, 14, 28, and 29 to measure changes in forced expiratory volume in one second (FEV1). They will also have chest X-rays or CT scans reviewed, complete questionnaires on breathlessness, and have regular assessments to monitor safety and treatment effects. Participants must be able to use the nebulizer properly and attend all study visits over approximately 7 weeks.

Researchers are evaluating the safety and effectiveness of HLX22 combined with trastuzumab and chemotherapy as the first treatment for patients with HER2-positive locally advanced or metastatic adenocarcinoma of the gastric or gastroesophageal junction. This phase 2, double-blind, randomized, and multiregional study compares this combination against trastuzumab and chemotherapy with or without pembrolizumab. The study aims to measure how well the treatments work in controlling the disease and improving survival for up to five years. Participants will be randomly assigned to one of two groups. One group receives HLX22 at 15 mg/kg every three weeks along with trastuzumab, chemotherapy (XELOX regimen), and possibly a placebo for pembrolizumab. The other group receives a placebo for HLX22 plus trastuzumab, chemotherapy (XELOX), and possibly pembrolizumab every three weeks. Treatment continues until the disease worsens, unacceptable side effects occur, withdrawal of consent, or other protocol-specified reasons. Throughout the study, participants will undergo regular assessments including tumor scans reviewed by an independent committee to evaluate progression-free survival and overall survival over up to five years. Other evaluations include safety monitoring and organ function tests. The study tracks how long patients live without disease progression and overall survival, aiming to better understand the benefits and risks of HLX22 combined with current standard treatments.

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 efficacy and safety of utidelone combined with capecitabine in patients who have HER2-negative breast cancer with brain metastases. This is a pivotal Phase II multicenter clinical trial that aims to assess both intracranial and systemic treatment effects in this patient population. The study focuses on comparing utidelone alone and utidelone with capecitabine to determine their impacts on brain metastases and overall disease control. Participants will receive utidelone intravenously once daily for five consecutive days every 21 days. In combination treatment groups, capecitabine is taken orally twice daily for days 1 to 14 of each 21-day cycle. Different dosing regimens of utidelone (25 or 30 mg/m2) combined with a fixed capecitabine dose (1000 mg/m2) are evaluated. Treatment cycles repeat every 21 days, and patients may receive multiple cycles as part of the study. During the study, participants will undergo regular assessments including brain MRI scans to measure intracranial tumor response according to RECIST 1.1 criteria over 12 months. Researchers will monitor safety, side effects, and systemic disease progression. Patients’ blood and organ function will be checked to ensure treatment tolerance. The main outcome is the intracranial objective response rate after treatment, with ongoing monitoring to evaluate both efficacy and safety throughout the study period.

Researchers are evaluating efruxifermin (EFX) in adults aged 18 to 80 who have compensated cirrhosis caused by nonalcoholic steatohepatitis (NASH) or metabolic dysfunction-associated steatohepatitis (MASH). This Phase 3, randomized, double-blind, placebo-controlled study aims to assess the safety and effectiveness of EFX in improving liver health and delaying disease progression in this population. The study focuses on subjects with advanced liver fibrosis (stage 4) but without liver decompensation. Participants are randomly assigned to receive either efruxifermin or a placebo, both administered by subcutaneous injection. The study includes two cohorts: Cohort 1 requires biopsy confirmation of liver fibrosis and specific metabolic features, while Cohort 2 allows biopsy or non-invasive diagnosis. Treatment and observation continue over an extended period to evaluate changes in liver fibrosis and clinical events. During the study, researchers will monitor the time until significant clinical events such as disease progression or liver decompensation occur, with a follow-up of up to five years. For Cohort 1, the proportion of participants showing improvement in fibrosis without worsening steatohepatitis will be assessed at 96 weeks. Participants will undergo regular evaluations including clinical assessments and laboratory tests to track liver function and safety throughout the study period.

Researchers are investigating the safety and effectiveness of efruxifermin in people with non-cirrhotic nonalcoholic steatohepatitis (NASH) or metabolic dysfunction-associated steatohepatitis (MASH) who have moderate to advanced liver fibrosis (stage 2 or 3). This Phase 3 study is randomized, double-blind, and placebo-controlled, enrolling a total of 1650 participants in two groups to evaluate treatment outcomes. Participants will receive either efruxifermin or a placebo by subcutaneous injection. The study involves two cohorts, with Cohort 1 including patients who have biopsy-confirmed NASH or MASH and specific liver fibrosis and activity scores. The treatment period and detailed dosing schedules are not provided but the study compares the effects of the active drug against placebo. During the study, participants will be monitored for improvement in liver disease status, including resolution of NASH/MASH and at least a one-stage improvement in liver fibrosis after 52 weeks for Cohort 1. Long-term outcomes such as event-free survival will be observed over 240 weeks. Safety and efficacy assessments will be conducted throughout the study period, including evaluations of liver histology and metabolic health.
