Researchers are evaluating MDNA11, a long-acting "beta-only" recombinant interleukin-2 designed to activate immune cells that attack cancer while minimizing stimulation of cells that suppress immunity. This Phase 1/2 open-label study aims to assess the safety, tolerability, pharmacokinetics, pharmacodynamics, and early anti-tumor activity of MDNA11 alone or combined with pembrolizumab in patients with advanced or metastatic solid tumors. The study includes dose-escalation and dose-expansion parts for both monotherapy and combination therapy with pembrolizumab. MDNA11 is given intravenously every two weeks with doses ranging from 0.003 to 0.6 mg/kg for monotherapy, while dose ranges for combination therapy are also evaluated. Treatment continues until progression, withdrawal, or loss to follow-up, with tumor assessments by CT or MRI every 8 weeks. Participants will undergo regular imaging scans every 8 weeks to monitor tumor response and safety assessments throughout the 24-month study. Researchers will track recommended doses for expansion, treatment-related adverse events, and overall safety. The study involves up to 115 patients across multiple sites and includes long-term monitoring for up to 24 months.

Researchers are evaluating new treatment options for adults with locally advanced or metastatic colorectal cancer that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This study compares the safety and effectiveness of adding calderasib and cetuximab, both targeted therapies, to a standard chemotherapy regimen called mFOLFOX6. The goal is to see if this combination can help patients live longer without their cancer growing or spreading compared to current treatments that may include mFOLFOX6 with or without bevacizumab. The study has two parts. It involves treatment with calderasib taken as an oral tablet, cetuximab given according to standard procedures, and mFOLFOX6 chemotherapy combining oxaliplatin, leucovorin/levofolinate calcium, and 5-fluorouracil. Some participants may receive bevacizumab or a bevacizumab biosimilar as part of the comparison. The treatments are given following approved dosing schedules. This design allows researchers to assess the safety and tolerability of these drug combinations in treating this type of colorectal cancer with the KRAS G12C mutation. Participants will be monitored for side effects, treatment tolerability, and cancer progression over a period that may last up to about 44 months. Researchers will track outcomes such as how many participants experience dose-limiting toxicities or adverse events, how many stop treatment due to side effects, and progression-free survival time. Assessments include health evaluations, laboratory tests, and imaging to observe cancer status. This long-term follow-up aims to understand both safety and effectiveness of the treatment combinations.

Researchers are investigating treatments for women with recurrent endometrial cancer that expresses different levels of the HER2 protein. The study has two groups based on the tumor's HER2 score: Cohort 1 includes patients with HER2 IHC 1+ or 2+ who have previously received immune checkpoint inhibitors and platinum-based chemotherapy, while Cohort 2 includes patients with HER2 IHC 3+. The purpose is to compare the effectiveness and safety of the investigational drug BNT323 (also called DB-1303) against chemotherapy in Cohort 1 and to evaluate BNT323 alone in Cohort 2. The study also looks at how the drug affects the immune system, the body's handling of the drug, quality of life, and potential side effects. Participants in Cohort 1 are randomly assigned to receive either BNT323 via intravenous infusion or a chemotherapy drug chosen by the investigator (doxorubicin, paclitaxel, or docetaxel if paclitaxel is unsuitable). Treatment continues until the cancer progresses, unacceptable side effects occur, or the participant withdraws consent. Those in Cohort 2 receive BNT323 alone until disease progression or other discontinuation criteria are met. The study includes a screening period, a treatment period expected to last about six months, followed by safety monitoring, efficacy follow-up, and long-term survival follow-up lasting up to approximately 53 months. During the study, participants undergo regular assessments including imaging scans to measure tumor response by RECIST criteria, safety monitoring for adverse effects, and evaluations of quality of life. Researchers also study the pharmacokinetics of BNT323 and the immune response. The main outcomes measured are progression-free survival in Cohort 1 and objective response rate in Cohort 2. Safety follow-up ensures ongoing monitoring after treatment to evaluate longer-term effects and participant wellbeing.

Researchers are evaluating the safety and effectiveness of trontinemab in people aged 50 to 90 with early symptoms of Alzheimer's disease, ranging from mild cognitive impairment to mild dementia. This Phase III clinical trial focuses on those who show evidence of Alzheimer's pathology and have a recent history of cognitive decline. The study aims to measure changes in cognitive function over 72 weeks. Participants will be randomly assigned to receive either intravenous trontinemab or a placebo. The trial is designed as a double-blind, placebo-controlled study, meaning neither participants nor researchers know who receives the active drug or placebo. The treatment period lasts up to 72 weeks, during which participants will undergo various assessments to monitor their cognitive status and safety. During the study, participants will complete clinical tests including cognitive assessments and imaging such as MRI, PET scans, or cerebrospinal fluid analysis to confirm Alzheimer's pathology. A study partner will assist participants as needed. Researchers will track changes from the start of the study through week 72 using tools like the Clinical Dementia Rating. Safety monitoring and adherence to study procedures will also be closely observed throughout the trial.

Researchers are evaluating the safety, tolerability, how the body processes the drug, and early antitumor effects of BG-C137, an antibody-drug conjugate targeting FGFR2b, alone and combined with other anticancer drugs in people with advanced solid tumors. This study includes two phases: Phase 1a focuses on dose escalation and safety, while Phase 1b involves dose expansion. The trial is sponsored by BeOne Medicines, formerly BeiGene. Participants receive BG-C137 through intravenous infusion. In combination groups, anticancer agents are given either intravenously or orally. Phase 1a includes monotherapy dose escalation, safety expansion, and combination dose confirmation and safety expansion. Phase 1b focuses on dose expansion. The study will determine the maximum tolerated dose, recommended doses for expansion, and overall response rates over approximately two years. During the study, participants will undergo evaluations including safety monitoring for adverse events, pharmacokinetic and pharmacodynamic assessments, and tumor response measurements using RECIST v1.1 criteria. Researchers will collect tumor tissue samples to assess FGFR2b expression and other biomarkers. Participants' physical function, organ health, and prior treatments will be reviewed. The total study duration may last up to about two years, with close monitoring of side effects and treatment effects throughout.

Researchers are evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, and early antitumor effects of BGB-53038, a pan-KRAS inhibitor, in people with advanced or metastatic solid tumors that have KRAS mutations or amplifications. The study also explores using BGB-53038 alone or combined with tislelizumab in nonsquamous non-small cell lung cancer and with cetuximab in colorectal cancer. This first-in-human, open-label, multicenter study has two phases: Phase 1a for dose escalation and safety expansion, and Phase 1b for dose expansion. Participants receive BGB-53038 orally. In combination groups, tislelizumab and cetuximab are given by intravenous infusion to participants with specific cancers. The study evaluates different doses to find the maximum tolerated dose, recommended doses for further study, and overall response rates over approximately two years. Throughout the study, participants are closely monitored for adverse events, treatment responses, and drug effects. Researchers collect data on safety, tolerability, and preliminary antitumor activity. The total study duration includes dose escalation, expansion phases, and follow-up assessments lasting up to about two years.

Researchers are evaluating the safety, tolerability, pharmacokinetics, and pharmacodynamics of IMP1734, a PARP1 selective inhibitor, in participants with advanced solid tumors. The study aims to assess preliminary efficacy and find the best dosing for future clinical development. This first-in-human trial is conducted in two parts, focusing on patients with recurrent, advanced, or metastatic solid tumors including metastatic prostate, ovarian, breast, and other solid tumors with specific genetic mutations. The trial has two main phases: Part 1 involves dose escalation of IMP1734 as a monotherapy to determine the maximum tolerated or achievable dose in solid tumors. Part 2 focuses on dose optimization to select the optimal dose for further clinical use. Treatment involves oral administration of IMP1734, with dose escalation steps and combination dose escalations in specific cancers like metastatic prostate cancer, ovarian, and breast cancer. Participants will undergo regular assessments to monitor safety through adverse event tracking, pharmacokinetic and pharmacodynamic evaluations, and tumor response measurements using criteria like RECIST1.1, CA125, or PSA. The study includes monitoring for serious adverse events from consent until 30 plus 7 days after the last dose. Dose-limiting toxicities are assessed during the first treatment cycle. Participants are expected to have adequate organ function, a life expectancy of at least 12 weeks, and will be followed closely during the trial to evaluate the drug's safety and potential anti-tumor activity.

Researchers are conducting a Phase 1/2 study to evaluate the safety and tolerability of BDC-4182, an immune stimulating antibody conjugate, in patients with advanced gastric and gastroesophageal cancers. This first-in-human trial aims to find the recommended Phase 2 dose by gradually increasing doses and monitoring participants closely. The study focuses on patients with measurable metastatic or unresectable cancer who have already undergone prior standard treatments or cannot tolerate them. Participants will receive BDC-4182, which combines an anti-claudin 18.2 monoclonal antibody with a TLR 7/8 dual agonist, delivered as a single agent. The study includes a dose escalation phase where participants are enrolled in cohorts until the maximum tolerated dose is found. Additional participants may join backfill cohorts for further safety data or the expansion phase at the recommended dose level. Throughout the study, participants will undergo biopsies or tumor sample collection before enrollment. Researchers will monitor adverse events up to around two years, including serious and dose-limiting toxicities within the first 21 days. Organ function and other health assessments will be performed to ensure safety. The trial carefully tracks treatment effects and tolerability in this patient population over the course of the study.

Primary immune thrombocytopenia (ITP) is a condition in which the immune system mistakenly destroys platelets, the cells that help stop bleeding. This leads to a low platelet count, making it easier to bruise or bleed. The trial investigates the long-term safety, tolerability, and effectiveness of mezagitamab in adults with chronic primary ITP who have previously participated in certain mezagitamab studies. It also examines how the body processes mezagitamab over time. Participants who completed the previous mezagitamab studies TAK-079-3002 or TAK-079-1004 and meet specific criteria will receive mezagitamab as a subcutaneous injection during this continuation study. The study is open-label and multicenter, focusing on continued treatment based on protocol requirements. The medication is given under medical supervision, and participants return to the study clinic several times throughout the study. During their participation, individuals will undergo regular assessments including monitoring for treatment-emergent adverse events and serious adverse events up to approximately 108 weeks. Researchers will track safety by noting any adverse events that lead to permanent withdrawal from mezagitamab. The study includes physical evaluations, laboratory tests, and ongoing safety monitoring to understand how well participants tolerate the treatment and how effective it is over the long term.

Researchers are studying adults with confirmed Primary Biliary Cholangitis (PBC) and cirrhosis, a scarring of the liver caused by damage to bile ducts. PBC is a slowly progressing disease that causes bile acid buildup and further liver damage, which can lead to cirrhosis. This study aims to evaluate if elafibranor, a daily medication, can prevent worsening clinical outcomes such as the need for liver transplant or death, compared to a placebo. It also looks at the safety of long-term elafibranor use and its effect on symptoms like itching and tiredness. Participants will take either an 80 mg tablet of elafibranor or a matching placebo once daily for up to 3.5 years in a double-blind setup, meaning neither the participants nor researchers know who receives which treatment. This long-term treatment period is designed to monitor the drug's impact over time. The study includes two groups: one receiving elafibranor and the other receiving placebo, with treatment lasting up to approximately 42 months. During the study, participants will be regularly assessed from the start until 4 weeks after treatment ends, with a maximum involvement of 3.5 years. Researchers will measure event-free survival, tracking if participants avoid clinical events indicating disease worsening. Safety monitoring will include tracking side effects and overall health, while symptom impact will be evaluated. Participants will provide informed consent and follow the study protocol throughout this extended observation period.
