Researchers are evaluating 177Lu-BetaBart, a 177Lu-labeled anti-B7-H3 monoclonal antibody, in patients with various relapsed or refractory solid tumors that are locally advanced, inoperable, or metastatic. This Phase 12a study aims to understand the safety, tolerability, how the drug moves through and affects the body, and early signs of anti-tumor activity. Eligible participants include adults 18 and older with cancers such as castration-resistant prostate cancer, colorectal cancer, lung cancers, head and neck cancer, ovarian, cervical, endometrial, triple negative breast cancer, and esophageal squamous cell carcinoma who have shown disease progression after recent treatments. The study has two main parts a Phase 1 dose escalation phase to find the maximum tolerated or recommended dose using a Bayesian design, and a Phase 2a dose expansion phase at that recommended dose to confirm safety and observe preliminary anti-tumor effects. Participants receive 177Lu-BetaBart through intravenous infusions every six weeks. Each phase includes a screening period, treatment and imaging period, and a safety and long-term follow-up period to closely monitor outcomes and side effects. During the study, participants undergo assessments including imaging for disease evaluation, laboratory tests for organ function and drug effects, and monitoring of side effects for up to 30 weeks. Key outcomes include determining the suitable dose for future studies, tracking adverse events, and measuring anti-tumor activity through objective response rates and biochemical responses in prostate cancer. Pharmacokinetics, radiation dosimetry, and biokinetics of the drug are also measured at specified time points. Safety and tolerability are evaluated continuously, with follow-up to monitor long-term effects and overall health.

Researchers are evaluating the imaging agent 64Cu-LNTH-1363S in patients with sarcomas or gastrointestinal tract GIT cancers to assess its safety, determine the best imaging dose and timing, and compare the imaging results with fibroblast activation protein FAP expression in tumor samples. This Phase 12a open-label study is divided into two parts and aims to better understand how this radiolabeled agent behaves in the body and how well it highlights tumors that express FAP. In Part 1, six patients with metastatic sarcomas will receive a fixed dose of 64Cu-LNTH-1363S to evaluate its distribution, radiation dose, and optimal imaging window during a one-day intervention, followed by a safety follow-up. In Part 2, approximately 20 patients with non-metastatic, operable sarcomas or GIT cancers scheduled for surgery will receive the optimal dose determined in Part 1 to study the correlation between imaging results and tissue FAP expression. Both parts include detailed cardiac monitoring to assess any changes in heart activity related to the agent. Participants will undergo screening before receiving the imaging agent, followed by serial PETCT scans at multiple timepoints on the intervention day to measure biodistribution and image quality. Tissue samples collected during surgery will be analyzed to compare with imaging findings. Safety and tolerability will be monitored through follow-up visits, ECGs, and phone contact. The total study duration varies from about three weeks for Part 1 to up to 11 weeks for Part 2, including surgery and post-surgery sample collection.

Researchers are evaluating the safety and effectiveness of two drugs, 64Cu-SAR-bisPSMA and 67Cu-SAR-bisPSMA, in men with prostate cancer that has spread and no longer responds to hormone-lowering treatments. This study focuses on cancers that express a protein called PSMA and aims to find safe and effective dosing while monitoring how the drugs behave in the body. Participants will go through different study phases. In the initial dosimetry phase, a single dose of 200 MBq of 64Cu-SAR-bisPSMA is given. Later phases involve receiving multiple doses of 64Cu-SAR-bisPSMA or 67Cu-SAR-bisPSMA, with doses and number of administrations varying by phase and participant group. The dose escalation phase tests increasing doses of 67Cu-SAR-bisPSMA, followed by a cohort expansion phase with up to six doses of the recommended 67Cu-SAR-bisPSMA dose. During the study, participants will undergo PETCT scans to track drug distribution and dosimetry within 48 hours of dosing. Researchers will measure prostate-specific antigen PSA levels and radiographic responses over up to five years to evaluate treatment effects. Safety will be monitored through assessments of vital signs, ECGs, laboratory tests, and recording any adverse events. The total study duration can extend up to five years for long-term follow-up.

Researchers are evaluating calderasib alone or combined with cetuximab to treat people with advanced solid tumors that have the KRAS G12C mutation, excluding colorectal cancer. This study aims to measure how many participants experience tumor shrinkage or disappearance and compare the responses between the two treatments. It is a phase 2, open-label trial focused on treatment safety and tolerability. Participants will receive calderasib orally with no set limit on treatment cycles. Some participants will also receive cetuximab via intravenous infusion every two weeks. Treatment continues until criteria for stopping the study intervention are met. The trial uses a randomized, parallel design to compare the two experimental arms. Throughout the study, participants will be monitored for tumor response, adverse events, and treatment discontinuations related to side effects. Researchers will also assess progression-free survival, duration of response, and overall survival up to about 76 months. The trial lasts until April 2032, with ongoing safety and efficacy evaluations during this period.

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 the safety, efficacy, and optimal dosing of a combination of two investigational treatments, BNT323 trastuzumab pamirtecan and BNT327 pumitamig, in people with advanced breast cancer. This includes those with hormone receptor-positive or -negative, HER2-positive, HER2-low, HER2-ultralow, HER2-null breast cancer, or triple-negative breast cancer. The study is a Phase III multi-site, open-label trial with a focus on advanced breast cancer treatment options. The study has two parts. Part 1 involves dose escalation of BNT323 combined with BNT327 to determine the recommended Phase 2 dose using six different dose levels. Part 2, which begins after Part 1 completion, includes dose optimization and exploratory cohorts. Cohort 1 in Part 2 uses randomization into four treatment arms, including combination therapy at different doses and monotherapies of either BNT323 or BNT327. Other cohorts receive the recommended dose without randomization. Participants will undergo assessments including tumor scans and cardiac function tests, with monitoring for side effects and tumor response up to 36 months. Researchers will track dose-limiting toxicities and treatment-emergent adverse events during early treatment cycles and monitor objective response rates and disease control over time. Safety and efficacy data will be collected through scheduled visits and tumor assessments during and after treatment to evaluate the study drugs effects and tolerability.

Researchers are evaluating new treatment combinations involving BNT314 and pumitamig alongside chemotherapy in people with metastatic colorectal cancer mCRC that is microsatellite stable or mismatch repair proficient. This study includes three parts Part A focuses on safety and dose escalation of BNT314 with pumitamig Part B assesses safety and dosing of BNT314 combined with pumitamig and standard chemotherapy in treatment-nafve or previously treated patients Part C tests effectiveness of these combinations compared to usual chemotherapy treatments. The study aims to see if these treatments can shrink tumors or slow cancer growth. Participants receive intravenous infusions of BNT314 and pumitamig, along with standard of care SoC chemotherapy, in various dose levels and combinations depending on the study part. Part A evaluates up to five dose levels of BNT314 and one or two doses of pumitamig. Part B uses optimized doses of BNT314 with pumitamig and one of two chemotherapy regimens. Part C compares the recommended BNT314 and pumitamig doses plus chemotherapy against other treatment combinations, including bevacizumab with chemotherapy or pumitamig with chemotherapy. Treatment continues until disease progression, intolerance, withdrawal, or study end. Participants undergo eligibility screening, then receive treatment for an average of 6 to 10 months. They are regularly monitored for safety and treatment effects, including tumor response and side effects, with assessments extending up to 57 months after starting treatment. After treatment ends, participants enter safety follow-up and long-term survival monitoring to track any lasting effects and overall outcomes. Randomization is used in Parts B and C to assign treatments by chance.

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 exploring new treatment options for neovascular age-related macular degeneration NVAMD, a condition affecting the eyes. This trial aims to compare a new medicine called tiespectus also known as MK-8748 or EYE201 with the standard treatment aflibercept to see if tiespectus works as well in treating NVAMD. The study includes adults aged 50 and older who have not previously received treatment for this condition. Participants will be randomly assigned to one of three groups tiespectus low dose, tiespectus high dose, or aflibercept. Those in the tiespectus groups will receive three initial injections every 4 weeks, followed by injections every 8 weeks up to week 48. After week 48, treatment will continue at intervals based on individual response until week 92. The aflibercept group will receive three initial injections followed by injections every 8 weeks until week 92. During the study, participants will have their vision tested using the Best-Corrected Visual Acuity BCVA score and their eye structure examined with imaging techniques. Researchers will monitor changes in vision over one year and track any side effects up to approximately 96 weeks. Participants will attend regular visits for treatment and assessments throughout the study period lasting about 92 weeks.

Researchers are evaluating the safety and dosing of COM503, given alone or with zimberelimab, in adults with advanced solid tumors. This first-in-human trial aims to find the maximum tolerated dose and recommended phase 2 dose of COM503 as both monotherapy and combined with zimberelimab. It focuses on advanced solid malignancies where standard treatments have failed or are unsuitable. The study includes several parts dose escalation of COM503 alone, dose escalation of COM503 combined with a fixed dose of zimberelimab, and dose expansion phases for both the monotherapy and combination therapy. Participants receive COM503 andor zimberelimab via intravenous infusion according to the assigned study part. During the trial, participants will undergo evaluations to monitor safety and tolerability from the first dose until 90 days after the last dose or the start of new anticancer therapy. Imaging with CT or MRI will assess tumor response. Researchers will track adverse effects, dosing limits, and overall safety profile over the study period. The trial is expected to last until November 2027.
