Angiosarcoma

Researchers are evaluating a new PET imaging tracer called [18F]FAPI-74 to detect cancer by targeting the fibroblast-activation protein (FAP) found in cancer-associated fibroblasts. This study aims to compare [18F]FAPI-74 PET scans to the standard [18F]-FDG PET scans and other imaging methods like CT or MRI across several cancers including pancreatic ductal adenocarcinoma, cholangiocarcinoma, hepatocellular carcinoma, gastric, bladder, ovarian cancers, pheochromocytoma/paraganglioma, small cell lung cancer, neuroendocrine cancer, mesothelioma, and sarcoma. The study is a phase 2 interventional trial conducted by the National Cancer Institute (NCI). Participants will receive an intravenous dose of [18F]FAPI-74 before undergoing PET/CT imaging about one hour later. They will also have a baseline FDG PET scan within one week. If tumors are detected by [18F]FAPI-74, additional scans using this tracer and FDG may be repeated during routine treatment and if cancer progresses within two years. Those with negative baseline [18F]FAPI-74 scans will not have repeated scans but remain in follow-up. The study involves a single arm where participants undergo both types of PET imaging. During the study, participants will have scans at baseline and potentially at subsequent treatment or progression points. Safety monitoring includes observation for reactions to the tracer up to three days after injection. Researchers will measure the mean number of lesions, standardized uptake values at baseline, post-treatment, and recurrence. Follow-up calls will continue for two years to assess progression-free survival and overall survival. The total participation duration includes imaging visits and two years of follow-up monitoring.

Researchers are evaluating a shorter course of preoperative radiation therapy for patients with soft tissue sarcoma located in the extremity, trunk, or retroperitoneum. This study aims to examine the safety and effectiveness of delivering radiation over five days, compared to the standard treatment which is spread over 25 days. The trial is a Phase 2 study sponsored by Stanford University focused on improving treatment convenience while monitoring outcomes. Participants receive external beam radiotherapy with a total dose of 30 Gy divided into five daily treatments, each delivering 6 Gy. This abbreviated radiation schedule is given prior to surgery, following the standard care plan of preoperative radiation and surgical resection. The study does not include a comparison group and is not blinded. During the trial, participants are monitored for complications occurring up to 120 days after surgery to assess safety. Researchers also track the rate of local cancer recurrence at 2 and 5 years post-surgery. Patients will undergo regular assessments related to treatment response and side effects to evaluate outcomes. Participation duration includes radiation treatment, surgery, and long-term follow-up for cancer control.

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 1/2a 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 PET/CT 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 use of 68Ga-DOTATATE digital PET/CT imaging in diagnosing soft tissue sarcomas. This study aims to assess the feasibility and potential clinical benefits of this imaging method, which may improve image quality compared to existing PET techniques. It also explores tumor uptake kinetics and the possibility of using imaging results to plan future peptide receptor radionuclide therapy for patients with specific tumor types. Participants receive an intravenous injection of gallium Ga 68-HA-DOTA-TATE and undergo digital PET/CT scanning for 60 minutes within two weeks after starting standard chemotherapy. About 24 hours later, they are given a fludeoxyglucose F-18 injection, followed by another 60-minute digital PET/CT scan. The study uses advanced PET detector technology to evaluate tumor characteristics and simulate imaging with lower doses or faster acquisition times. During the study, participants undergo imaging assessments to measure regions with increased tracer uptake. Researchers monitor safety by tracking adverse events up to seven days after imaging. The study involves standard chemotherapy alongside the imaging procedures. The total participation duration varies but includes the imaging sessions around chemotherapy and safety follow-up shortly after. This research is sponsored by Ohio State University Comprehensive Cancer Center.

Soft Tissue Sarcoma (STS) is a cancer that forms in soft tissues like muscles, tendons, fat, blood vessels, and nerves. These tumors often have a protein called PDGFRb1, which is targeted by treatments such as olaratumab. This trial is evaluating a new imaging agent, 89Zr-TLX300-CDx, which combines olaratumab with a radioactive metal, zirconium-89, to help detect STS and identify patients who might benefit from future PDGFRb1-targeted therapies. Participants will receive a single injection of 89Zr-TLX300-CDx and undergo whole-body imaging at various times depending on the study part. Part A and B include imaging at about 6 days after injection, with optional imaging at 4 hours. Part C involves imaging at 24 hours, 4 days, and 7 days post-injection, plus optional early dynamic imaging. Blood samples will be taken before injection and at multiple time points afterwards to study how the drug moves through the body. During the study, participants will have imaging scans and blood collections to assess safety, how the drug spreads and is processed, radiation exposure, and tumor targeting. The primary outcomes include safety and tolerability over 30 days, biodistribution and radiation dosimetry at 6 days, and pharmacokinetics. The study will help guide the future use of olaratumab as a radiopharmaceutical for STS. Participation involves visits for injections, imaging, and blood tests, with monitoring continuing for up to 30 days.

Researchers are studying the safety and initial effects of T3011, given directly into tumors, alone and combined with the intravenous drug pembrolizumab. This Phase 1/2a open-label study focuses on adults with advanced or metastatic solid tumors, including melanoma, head and neck squamous cell carcinoma (HNSCC), sarcoma, cutaneous squamous cell carcinoma (cSCC), and non-small cell lung cancer (NSCLC). The study aims to find safe dose levels and assess how well these treatments are tolerated and work in these cancer types. The study involves several groups: Phase 1 tests increasing doses of T3011 alone to determine a recommended dose. Phase 2a Part 1 evaluates T3011 alone in participants with melanoma, HNSCC, sarcoma, and cSCC. Phase 2a Part 2 studies T3011 with pembrolizumab in NSCLC patients. A rollover arm allows participants whose cancer progresses on T3011 alone to receive the combination treatment. T3011 is given as an intratumoral injection every two weeks, and pembrolizumab is given intravenously every three weeks when combined. Participants will have tumor biopsies, imaging, and laboratory tests to monitor safety, drug levels, and cancer response. Researchers will track side effects and measure outcomes like tumor response and survival for up to two years after the first dose. Safety and tolerability are closely followed throughout, with additional monitoring for immune responses and drug presence in bodily fluids. Participants may be followed for up to one year after their last treatment dose to assess overall survival and long-term effects.

Researchers are evaluating the safety and effectiveness of a modified herpes simplex virus called recombinant oncolytic herpes simplex virus type 1 (R130) in patients with advanced solid tumors. This early phase 1, open, single-arm clinical trial aims to study the treatment in people with various cancers such as sarcoma, carcinoma, digestive cancer, breast cancer, lung cancer, brain cancer, melanoma, gynecologic cancer, head and neck cancer, and kidney cancer. The study focuses on patients who have not responded to standard treatments or who choose not to receive other antitumor therapies. Participants will receive injections of 1 to 2 milliliters of R130 at a concentration of 1x10^8 plaque-forming units per milliliter into their tumors or abdominal cavity every 7 to 14 days. This approach allows the virus to be delivered directly to the cancer site. The study involves only one treatment group receiving the R130 virus, and no placebo or comparison group is used. During the trial, researchers will monitor participants for adverse events and laboratory abnormalities up to 6 months and assess their immune response. Disease control and response duration will be evaluated every 10 weeks for up to 12 months, while quality of life assessments will occur every 6 weeks for the same period. Participants will undergo regular laboratory tests and clinical evaluations to track safety and treatment impact. The total study duration for each participant may extend up to one year with ongoing monitoring.

Researchers are studying the safety and effectiveness of a modified herpes simplex virus called R130 for treating advanced bone and soft tissue tumors, including osteosarcoma and sarcoma. This early-phase, open-label clinical trial aims to learn how this oncolytic virus works in patients who have relapsed or refractory tumors and have not responded to standard treatments or choose not to receive other therapies. Participants will receive injections of 1 to 2 ml of R130, containing 1x10^8 plaque-forming units per milliliter, directly into their tumors every 7 to 14 days. The treatment focuses on patients with measurable lesions suitable for direct injection. This single-arm study does not include a comparison group and is sponsored by Shanghai Yunying Medical Technology. During the study, patients will be closely monitored for adverse events and laboratory changes up to 6 months after treatment. Researchers will assess immune responses, disease control, duration of response, and quality of life over a 12-month period with scheduled evaluations every 6 to 10 weeks. Participants must meet certain health and organ function requirements and will be followed for safety and outcomes throughout the trial.

Researchers are evaluating the preliminary effectiveness of intratumoural tigilanol tiglate in patients with advanced or metastatic soft tissue sarcoma located in the extremities and body wall. This Phase IIa open-label study aims to assess tumour destruction following one or more treatments and the overall disease control beyond injected tumours. Additional goals include assessing safety, tolerability, systemic exposure, immune response, and progression-free survival in certain stages of the study. Participants will receive one or multiple injections of tigilanol tiglate directly into their tumours at a dose up to 3.6 mg/m2 based on body surface area. The treatment is administered intratumourally and may be guided by palpation or ultrasound. The study is open label with a single treatment arm, and the effects of the drug on injected and sometimes non-injected tumours will be monitored over time. Throughout the study, participants will undergo various assessments including tumour response evaluations at 3 and 6 months after initial treatment. Researchers will monitor adverse events for safety up to 6 months and perform pharmacokinetic testing after the first dose. Additional exploratory assessments include tumour microenvironment analysis, immune response, local recurrence rates, and metabolic profiling. Overall, participant involvement includes treatment, follow-up visits, safety monitoring, and outcome measurements lasting at least 6 months.

Researchers are evaluating a new T-cell membrane-anchored tumor targeted IL12 (attIL12)-T cell therapy combined with cyclophosphamide in patients with advanced or metastatic soft tissue or bone sarcomas. This phase 1 trial aims to find the best dose for treatment and to understand the safety, tolerability, and early signs of disease control, especially in patients with recurrent unresectable osteosarcoma. The study also explores immune responses and tumor cell changes related to the therapy. Participants will receive attIL12-T cell therapy combined with cyclophosphamide administered intravenously. The study includes two parts: Part A focuses on finding the safe and recommended dose, starting with the lowest dose, while Part B involves treating patients with osteosarcoma at the recommended dose found in Part A. Treatment schedules depend on the participant's group and study phase. During the trial, participants will undergo tumor biopsies when possible and provide blood samples to assess immune changes. Researchers will monitor adverse events to evaluate safety for about one year. The main measurement is the incidence of side effects, and disease control will also be assessed over four months. Participants must meet specific health and organ function criteria and will be closely followed up throughout the study period.
