Esophageal Squamous Cell Carcinoma

This is a Phase 1/2, open-label, multicenter study evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics and anti-tumor activity of TER-2013 in patients with advanced solid tumors harboring AKT/PI3K/PTEN pathway alterations.

The goal of this study is to evaluate the safety and effectiveness of EVOLVE104 in participants with advanced urothelial and squamous cell carcinomas who have previously taken standard treatment options, have declined or have been ineligible for treatment with these medications. Participants with advanced or metastatic cancer who meet all eligibility criteria may be eligible to participate in the study.

Researchers are looking for new ways to treat esophageal squamous cell carcinoma (ESCC). ESCC is a type of cancer that starts in certain cells that line the esophagus. The esophagus is the tube that connects the throat to the stomach. This study will look at ESCC that is either locally advanced unresectable, which means it has spread into tissue near where it started and cannot be completely removed by surgery, or metastatic, which means it has spread to other body parts. Available treatments for these types of ESCC include pembrolizumab and chemotherapy. Pembrolizumab is an immunotherapy, which is a treatment that helps the immune system fight cancer. Chemotherapy is medicine that destroys cancer cells or stops them from growing. Researchers want to learn about giving pembrolizumab and investigational agents, with or without chemotherapy to treat ESCC. Ifinatamab deruxtecan (I-DXd), is an antibody-drug conjugate (ADC). An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The main goal of this study is to learn about the safety of investigational agents and pembrolizumab with or without chemotherapy and if people tolerate them. Researchers also want to learn how cancer responds (gets smaller or goes away) to the study treatments.

This prospective, multicenter diagnostic accuracy study will develop and validate a standardized 3.0-T magnetic resonance imaging (MRI) acquisition protocol and structured reporting system for primary esophageal squamous cell carcinoma (ESCC). Approximately 500 adults scheduled for curative esophagectomy will be enrolled consecutively into two clinically defined cohorts. In Cohort A, patients proceeding directly to surgery will have MRI-based T staging compared with postoperative pathological T stage. In Cohort B, patients receiving neoadjuvant therapy before surgery will undergo paired MRI assessment, and MRI-based tumor regression grade will be compared with pathological tumor regression grade in the resected primary tumor bed. Imaging will be independently assessed by two radiologists, with adjudication by a third reader. The study will evaluate diagnostic performance, reader agreement, image quality, protocol adherence, reporting completeness, and consistency across participating centers and MRI vendors. Lymph-node staging and nodal treatment response are outside the research scope.

This study is designed to assess the efficacy and safety of ifinatamab deruxtecan (I-DXd) in patients with unresectable advanced or metastatic esophageal squamous cell carcinoma (ESCC) who have experienced disease progression following treatment with a platinum-based systemic therapy and an immune checkpoint inhibitor (ICI) compared with investigator's choice of chemotherapy (ICC).

This is a Phase III, multicenter, open-label, randomized controlled trial. The study aims to compare organ preservation versus esophagectomy in patients with locally advanced, resectable thoracic esophageal squamous cell carcinoma (ESCC) who achieve a complete or partial clinical response (cCR/cPR) following neoadjuvant immunochemotherapy.

The purpose of this study is to characterize the clinical effects of tislelizumab, including pharmacokinetics (PK), activity, and safety assessments in US racial and ethnic minority patients with human epidermal growth factor receptor 2 (HER2)-negative, programmed death-ligand 1(PD-L1)-positive, unresectable or metastatic gastric or gastroesophageal cancer (GAC/GEA) or esophageal squamous cell carcinoma (ESCC). The study duration will be up to approximately 6 years.

The purpose of the study is to explore the safety and effects of the study drug (PF-08046876) in people diagnosed with advanced cancer of the bladder, lung, head and neck, esophagus, or pancreas. PF-08046876 is an investigational anticancer therapy called an 'antibody drug conjugate' or 'ADC'. ADCs are anticancer drugs designed to stick to cancer cells and kill them. The study drug will be given to participants through a needle in a vein (intravenous infusion). This study includes multiple parts. In the first part of the study, there will be different groups of people receiving different doses of the study drug. The study may also test different schedules.

This study will test the safety of a drug called PF-08046054/SGN-PDL1V alone and with pembrolizumab in participants with solid tumors. It will also study the side effects of this drug. A side effect is anything a drug does to your body besides treating your disease. Participants will have solid tumor cancer that has spread through the body (metastatic) or cannot be removed with surgery (unresectable). This study will have five parts. Parts A and B of the study will find out how much PF-08046054/SGN- PDL1V should be given to participants. Part C will use the dose found in Parts A and B to find out how safe PF-08046054/SGN-PDL1V is and if it works to treat solid tumor cancers. In Part D and E, participants will be given PF-08046054/SGN-PDL1V with pembrolizumab to find out how safe this combination is and if it works to treat solid tumor cancers.

In the current protocol, we propose a study to evaluate a novel, combined esophageal sponge-methylation biomarker strategy for the early detection of esophageal squamous cell carcinoma (ESCC) as well as its precursor, esophageal squamous dysplasia (ESD). This strategy leverages the 'EsophaCap', a swallowable, retrievable sponge, with subsequent evaluation of the sample using a novel molecular biomarker assay. This biomarker assay evaluates methylation levels in select genes, which have been shown to differ significantly between ESCC cases and controls in pilot studies. Detection of methylation markers highly associated with ESCC could help identify patients with concurrent ESCC or at high risk of imminently developing this condition. If successful, this strategy could result in a paradigm shift for esophageal cancer control strategies in Tanzania and other high-incidence ESCC regions.

This multi-site, Phase 1/2 clinical trial is an open-label study to identify the safety, pharmacokinetics, and efficacy of a repeated dose regimen of NEO212 alone for the treatment of patients with radiographically-confirmed progression of Astrocytoma IDH- mutant, Glioblastoma IDH-wildtype, and the safety, pharmacokinetics and efficacy of a repeated dose regimen of NEO212 when given with select SOC for the treatment of solid tumor patients with radiographically confirmed uncontrolled metastases to the brain. The study will have three phases, Phase 1, Phase 2a and Phase 2b.

This is a Phase 1a, open label, single dose, extended study of safety and biokinetics of RAD301 in healthy human volunteers and individuals with PDAC or Other Solid Tumors

Immunotherapy combined with chemotherapy has become the first-line standard of care for advanced esophageal squamous cell carcinoma (ESCC), significantly improving patient survival. However, with the widespread adoption of first-line immunotherapy, most patients eventually develop immune resistance. After first-line treatment failure, there is currently no established standard effective therapy for second-line ESCC. Therefore, more effective and safer treatment options are urgently needed for second-line advanced ESCC. This is a prospective, single-arm, single-center, open-label, Phase II clinical study aiming to evaluate the efficacy and safety of Becotatug Vedotin combined with Tislelizumab and low-dose Lenvatinib in patients with advanced ESCC who have failed first-line therapy. Eligible patients will receive Becotatug Vedotin combined with Tislelizumab and low-dose Lenvatinib. The primary endpoint is objective response rate (ORR) assessed per RECIST v1.1. Secondary endpoints include progression-free survival (PFS), disease control rate (DCR), duration of response (DOR), overall survival (OS), and safety.

This trial is a registrational Phase II/III, randomized, controlled, open-label, multicenter study to evaluate the efficacy and safety of BL-B01D1 in combination with tislelizumab ± 5-FU in patients with unresectable, locally advanced recurrent or metastatic esophageal squamous cell carcinoma.

Esophageal cancer remains a disease with a poor prognosis. Chemotherapy is an important part of its treatment, but there are cases in which chemotherapy is ineffective. The investigators aim to develop a model to predict the response to chemotherapy by DNA methylation of preoperative biopsy specimens to identify the chemotherapy ineffective group.

The purpose of this study is to evaluate the safety, tolerability and preliminary antitumor activity of SKB500 combinations in patients with Esophageal Squamous Cell Carcinoma. The study is divided into three parts: the safety run-in phase, randomized enrollment phase and cohort expansion phase.

This is a multicenter, open-label, randomized, controlled clinical study to compare the efficacy and safety of cardonilizumab combined with neoadjuvant chemotherapy and surgery versus neoadjuvant chemoradiotherapy and surgery in locally advanced ESCC. Subjects were randomly divided into experimental group and control group, the experimental group received neoadjuvant immunotherapy concurrent chemotherapy regimen, the control group received neoadjuvant concurrent chemoradiotherapy regimen, and then received McKeown surgery. The primary outcome measures were complete pathological response (pCR), and the secondary outcome measures were major pathological response (MPR), EFS (event-free survival), OS (overall survival), overall response rate (ORR), decreased pathological stage, R0 resection rate, adverse events (AE), and perioperative complications

This study is a prospective, single-arm, single-center Phase Ib clinical trial of Becotatug Vedotin in combination with cisplatin and concurrent radiotherapy for locally advanced esophageal squamous cell carcinoma. The primary objectives are to investigate the maximum tolerated dose (MTD), dose-limiting toxicity (DLT), and recommended Phase II dose (RP2D) of Becotatug Vedotin in combination with cisplatin and concurrent radiotherapy for locally advanced esophageal squamous cell carcinoma. The secondary objectives are to assess the efficacy and safety of this combination regimen.

This study will test a new potential treatment for advanced esophageal squamous cell cancer (ESCC) for patients whose initial treatment has stopped working. Currently, the standard second-line treatment for this cancer is PD-1 inhibitors or chemotherapy alone, which is not very effective, allowing the cancer to grow again after just 1.6 to 3.4 months on average. Therefore, there is a strong need for more effective therapies. The new treatment is a type of drug called an antibody-drug conjugate (ADC). It is designed to target a specific protein called EGFR, which is found in high amounts on the surface of 50-70% of ESCC cancer cells and is linked to a poorer outlook for patients. This ADC works like a targeted delivery system: an antibody guides a powerful cell-killing drug directly to the cancer cells, aiming to destroy them while reducing harm to healthy cells. Although other drugs targeting EGFR have not successfully improved survival for ESCC patients, this new ADC offers a different and promising approach. The main goal of this study is to find out if this new EGFR-targeting ADC is effective in helping patients with advanced ESCC live longer without their cancer getting worse.

This trial will look at a drug called sigvotatug vedotin (SGN-B6A) alone and with pembrolizumab, with or without chemotherapy, to find out whether it is safe for people who have solid tumors. It will study sigvotatug vedotin to find out what its side effects are. A side effect is anything the drug does besides treating cancer. It will also study whether sigvotatug vedotin works to treat solid tumors. The study will have four parts. * Part A of the study will find out how much sigvotatug vedotin should be given to participants. * Part B will use the dose found in Part A to find out how safe sigvotatug vedotin is and if it works to treat solid tumors. * Part C of the study will find out how safe sigvotatug vedotin is in combination with these other drugs. * Part D will include people who have not received treatment. This part of the study will find out how safe sigvotatug vedotin is in combination with these other drugs and if these combinations work to treat solid tumors. * In Parts C and D, participants will receive sigvotatug vedotin with either: * Pembrolizumab or, * Pembrolizumab and carboplatin, or * Pembrolizumab and cisplatin.

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic, pharmacodynamic, preliminary anti-tumor activity, and to determine the recommended Phase II dose (RP2D) of the ALE.P02 monotherapy in adult patients with selected squamous solid tumors.

This is a Phase 1/2, multicenter, randomized, open-label umbrella platform study to evaluate the safety and efficacy of investigational agents with or without pembrolizumab and/or chemotherapy, for the treatment of participants with second line (2L) esophageal squamous cell carcinoma (ESCC) who have previously been exposed to PD-1/PD-L1 based treatment.

Biotherapies are biological (extracted from an organism or living tissue) or biotechnological drugs used in the treatment of multiple conditions, such as autoimmune inflammatory diseases, cancers, and hematologic diseases. In recent years, these biotherapies have notably emerged in the treatment of cancers and hematologic disorders. As such, most patients with cancers or hematologic diseases will likely receive a biotherapy as part of their care pathway. These biotherapies are associated with various side effects, including hypersensitivity or allergic reactions, which are often poorly characterized in clinical trials. These reactions manifest as symptoms without specific dermatologic or allergologic semiology (such as itching, erythema, shortness of breath, sometimes digestive issues, or discomfort, and in some cases, an anaphylactic reaction). Unlike other treatments, such as antibiotics and neuromuscular blockers, there are currently no guidelines on the concentrations to use in skin tests for biotherapies. We propose conducting prospective clinical research to scientifically establish the concentrations to be used when investigating hypersensitivity to a biotherapy, in line with best practice recommendations for drug skin testing.

This is a Phase 1a/1b, open-label, multicenter dose escalation and dose expansion clinical study to evaluate the safety, PK, immunogenicity and preliminary efficacy of IDE034 in participants with locally advanced/metastatic solid tumor types that express B7-H3 and PTK7.

This study is an open-label, biomarker-integrated umbrella trial designed to evaluate the clinical efficacy of molecular subtype- and genomic biomarker-guided precision therapies in patients with advanced esophageal cancer refractory to prior immunotherapy. Conducted in a two-step process, the study first enrolls patients with locally advanced or metastatic esophageal squamous cell carcinoma (ESCC) who have progressed on prior immunotherapy, performing circulating tumor DNA (ctDNA) sequencing to stratify them into three distinct treatment cohorts, after which patients receive tailored combination regimens matched to their specific molecular profiling in the second step. Specifically, Cohort 1 includes patients with high EGFR expression or activation of EGFR-related signaling pathways, who will receive Afatinib (40 mg, p.o., Q.D.) combined with Toripalimab (240 mg, i.v., Q21D) in a 21-day treatment cycle, continuing until radiographic disease progression (PD), unacceptable toxicity, loss to follow-up, death, or other investigator-determined criteria for discontinuation, with a maximum toripalimab treatment duration of 24 months. Cohort 2 comprises patients harboring genomic alterations directly associated with cell cycle regulation or activation of cell cycle signaling pathways, who will be treated with Dalpiciclib (125 mg, p.o., Q.D. for 21 consecutive days followed by a 7-day off period in a 28-day cycle \[Q4W\]) combined with Pyrotinib maleate (320 mg, p.o., Q.D., administered within 30 minutes post-meal, Q4W) until disease progression, unacceptable toxicity, initiation of a new anti-tumor therapy, withdrawal of consent, or investigator's decision for treatment discontinuation. Cohort 3 includes patients with other molecular profiles who do not fit Cohorts 1 or 2, who will receive Camrelizumab (200 mg, i.v., Q3W) and Apatinib (250 mg, p.o., Q.D.), with clinical efficacy evaluations performed every 6 weeks, continuing until radiographic PD, unacceptable toxicity, death, or treatment discontinuation, whichever occurs first. The study aims to recruit an estimated maximum of 90 subjects, enrolling up to 30 subjects per cohort, with the final sample size dependent on the observed toxicities and the prevalence of each molecular cohort within the screened population.
