Researchers are evaluating the combination of CGT9486 and sunitinib compared to sunitinib alone in patients with locally advanced, unresectable, or metastatic Gastrointestinal Stromal Tumors GIST. This Phase 3, open-label international trial involves multiple parts, including dose confirmation, drug interaction assessments, and efficacy comparisons. The study also includes substudies focusing on drug-drug interaction potential and first-line treatment in patients with specific genetic mutations KIT exon 9. Approximately 482 patients will participate across these parts.

Researchers are evaluating new imaging methods to better detect tumors in people with brain metastases. The study focuses on whether positron emission tomography PET combined with magnetic resonance imaging MRI can identify cancerous tissue more accurately than current imaging techniques. This is important for improving future cancer treatments and understanding tumor location and extent. Participants will undergo a single combined PETMRI scan using the F-Fluciclovine radiotracer, followed by a separate MRI scan using a tracer. These imaging methods use a powerful magnet, radio waves, and a computer to create detailed images and assess protein levels in tumors, which helps distinguish tumor tissue from normal brain tissue. During the study, participants will lie still for 30 to 60 minutes while imaging is performed, with the entire participation lasting about 3 hours. Researchers will measure amino acid uptake into tumor tissue during this time to evaluate the imaging effectiveness. The study is sponsored by the University of Wisconsin, Madison, and does not involve any treatment beyond imaging procedures.

Researchers are studying metastatic castration-resistant prostate cancer mCRPC to find new treatment options. This trial evaluates if the study medicine ifinatamab deruxtecan I-DXd or MK-2400 helps people live longer overall and experience slower cancer growth or spread compared to chemotherapy. The study is a Phase 3 trial comparing I-DXd with standard chemotherapy for mCRPC patients. Participants are randomly assigned to receive either I-DXd at 12 mgkg every 3 weeks through intravenous infusion or docetaxel chemotherapy at 75 mgm2 every 3 weeks combined with daily prednisone pills. Treatment continues until the disease progresses, unacceptable side effects occur, or treatment is stopped for other reasons. Premedication is given before each dose of I-DXd to help prevent nausea and vomiting. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess overall survival and radiographic progression-free survival for up to about 36 months. Additional measures include response rates, time to pain progression, PSA progression, and adverse events. The study tracks safety, treatment effects, and quality of life over a long follow-up period to better understand the potential benefits and risks of I-DXd compared to chemotherapy.

Researchers are evaluating KTX-2001 alone and in combination with darolutamide in men with metastatic castration-resistant prostate cancer mCRPC. This first-in-human, open-label Phase 1 study aims to assess the safety, dosage levels, and preliminary effectiveness of KTX-2001. The study also examines how these drugs behave in the body, intending to establish recommended doses for future research. Participants will receive escalating doses of KTX-2001 either alone or combined with darolutamide, an oral androgen receptor pathway inhibitor given at 600 mg twice daily total 1200 mg. The study has two parts Part A tests KTX-2001 monotherapy, and Part B tests KTX-2001 with darolutamide. Dose escalation occurs sequentially to determine the maximum tolerated dose and recommended Phase 2 dose. Participants will be monitored closely for dose-limiting toxicities over 21 days and overall safety up to three years. Assessments include pharmacokinetic measurements of drug concentrations in plasma and regular evaluations of health and side effects. Tissue biopsies of metastatic sites may be collected if safe and feasible. The study will continue until September 2028, with ongoing safety and efficacy follow-up throughout this period.

Researchers are investigating whether sacituzumab tirumotecan alone or combined with other treatments can treat certain advanced or unresectable gastrointestinal cancers, including colorectal cancer, pancreatic ductal adenocarcinoma, and biliary tract cancer. The study aims to understand the safety and tolerability of sacituzumab tirumotecan and how well the cancer responds to these treatments. Participants will receive sacituzumab tirumotecan in different dose levels either combined with chemotherapy every two weeks in a 4-week cycle, alone every two weeks in a 4-week cycle, or combined with cisplatin and pembrolizumab in a 3-week cycle. Treatment continues until the cancer worsens or participants cannot tolerate it. Cisplatin is given up to approximately six months, and pembrolizumab is administered for up to about two years in the combination group. During the study, participants will have regular assessments to monitor safety, side effects, and how the cancer responds via imaging and clinical evaluation. Researchers will track dose-limiting toxicities, adverse events, treatment discontinuations due to side effects, and objective response rates. Additional measures include duration of response, progression-free survival, and overall survival, with monitoring lasting up to approximately 63 months.

Researchers are investigating new treatment options for breast cancer that is hormone receptor-positive HR and human epidermal growth factor receptor 2-negative HER2-, specifically for cases that are unresectable locally advanced or metastatic. This type of breast cancer involves cancer cells that depend on hormones like estrogen or progesterone and have low HER2 protein levels. The study focuses on comparing the effects of patritumab deruxtecan against chemotherapy or trastuzumab deruxtecan in patients whose cancer has progressed despite prior treatments. Participants receive either patritumab deruxtecan through intravenous infusions every three weeks for about 13 months or a treatment chosen by their physician, which may include various chemotherapy drugs or trastuzumab deruxtecan, administered according to specific schedules for up to 13 months. The study is randomized and open-label, meaning participants are randomly assigned to one of the treatment groups, and both the patients and researchers know which treatment is given. Throughout the study, participants undergo regular assessments to monitor cancer progression and overall survival for up to approximately 85 months. Researchers evaluate tumor response, duration of response, and changes in quality of life using standardized questionnaires. Safety is carefully monitored by recording adverse events and treatment discontinuations. The goal is to understand if patritumab deruxtecan can improve outcomes compared to current treatment options.

Researchers are investigating new treatments for high-risk, early-stage breast cancer, specifically targeting two types triple-negative breast cancer TNBC and hormone receptor-low positiveHER2-negative breast cancer. These cancers are characterized by low or no HER2 protein and low hormone receptor presence. The study aims to evaluate if adding sacituzumab tirumotecan sac-TMT to pembrolizumab and chemotherapy can better reduce cancer cells in tumors and lymph nodes and improve the length of time patients live without cancer progression compared to pembrolizumab with chemotherapy alone. Participants in this trial receive one of two treatment plans. One group gets sacituzumab tirumotecan intravenously every two weeks plus pembrolizumab every three weeks for 12 weeks, followed by pembrolizumab with carboplatin and paclitaxel for another 12 weeks. After 3 to 6 weeks, surgery and optional radiation therapy take place, followed by pembrolizumab for about 28 weeks. Participants with remaining disease may receive additional treatments chosen by their doctors, including olaparib, capecitabine, doxorubicin, epirubicin, or cyclophosphamide. The other group receives chemotherapy drugs carboplatin and paclitaxel with pembrolizumab initially, then pembrolizumab with cyclophosphamide and doxorubicin or epirubicin, followed by surgery, optional radiation, and pembrolizumab for about 28 weeks, with similar additional options for residual disease. During the study, participants undergo core needle biopsies, receive intravenous infusions of study drugs, and have surgery and possible radiation therapy. Researchers assess outcomes such as the percentage of participants with no detectable cancer cells at surgery pathological complete response, event-free survival up to about 92 months, and overall survival up to nearly 10 years. Quality of life and side effects are monitored through questionnaires and adverse event tracking. The study lasts several years, with various assessments throughout treatment and follow-up periods to gather comprehensive data on treatment effects and safety.

Researchers are evaluating treatments for germinal center B-cell-like diffuse large B-cell lymphoma GCB DLBCL, a fast-growing blood cancer affecting immature B-cells. The study compares two treatment combinations to see if more people respond to zilovertamab vedotin MK-2140 plus R-CHP versus polatuzumab vedotin plus R-CHP. This Phase 2 trial aims to assess the effectiveness and safety of these regimens in participants with newly diagnosed GCB DLBCL. Participants receive either zilovertamab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone R-CHP, or polatuzumab vedotin combined with R-CHP. Treatments are given by intravenous infusion on Day 1 of each 3-week cycle for up to 6 cycles, approximately 4 months, with prednisone or prednisolone taken orally for 5 days of each cycle. For participants with high-risk DLBCL, up to 2 additional cycles of rituximab or biosimilar are given. During the study, participants are monitored for response to treatment using Lugano Response Criteria, with follow-up lasting up to about 31 months for the primary outcome. Secondary outcomes include progression-free survival, overall survival, event-free survival, duration of complete response, adverse events, and quality of life assessments. Safety and health status are regularly checked through exams, lab tests, and questionnaires over several years, with total study participation extending up to 7 years.

Researchers are evaluating the safety, effectiveness, optimal dose, and behavior of an investigational drug called BNT326, alone or combined with other immunotherapy agents, in adults with advanced solid tumors. This study includes patients with tumors that have either spread metastatic, returned after treatment, or progressed despite previous therapies, across various cancer types such as melanoma, lung cancer, breast cancer, gastric cancer, colorectal cancer, and cervical cancer. Participants are divided into two parts Part 1 tests BNT326 alone in different tumor-specific groups, some with dose randomization to find optimal dosing. Part 2 evaluates BNT326 alone or combined with another investigational drug called pumitamig in several cancer types, with some groups receiving randomized doses and others non-randomized treatments. Treatments are given via intravenous infusion, with some oral medications combined in Part 1. The study includes dose escalation and randomization phases, and treatment can continue for up to 24 months or until disease progression or other reasons. During the study, participants undergo screening, treatment, safety follow-up, efficacy follow-up, and long-term survival monitoring phases. Researchers assess adverse events, treatment responses, disease progression, and drug behavior in the body using clinical evaluations and laboratory tests. Follow-up assessments occur up to approximately 38 months for Part 1 and 48 months for Part 2, with continued treatment possible for those benefiting from the therapy. The study aims to gather comprehensive data on safety, dosing, and effectiveness in this patient population.

Researchers are evaluating the safety, tolerability, and effectiveness of Navepegritide TransCon CNP in infants with genetically confirmed achondroplasia ACH who are younger than 2 years old. This Phase 2, multicenter, double-blind, randomized, placebo-controlled trial aims to compare weekly doses of Navepegritide with a placebo over a 52-week period to understand its impact on growth and safety in this population.
