Filter by:This project is focusing on who have locally advanced esophageal squamous cell carcinoma and have undergone neoadjuvant and adjuvant therapy, followed by surgical resection. The exclusive MRD (Minimal residual disease) probe consists of an exclusive "molecular label" formulated according to the individual genome mutation profile and 21 critical tumor driver genes. By continuously monitoring each patient's ctDNA dynamics, changes in ctDNA concentration or ctDNA-MRD negative/positive results will serve as the primary indicators to assess the efficacy and prognosis of patients with esophageal squamous cell carcinoma.
This is a prospective, single-arm, open-label，multi-center, phase II study, aiming to evaluate the efficacy and safety of AK104 combined with preoperative chemotherapy in patients with locally advanced ESCC.
Background: Head and neck squamous cell carcinoma (HNSCC) is the 6th most common cancer worldwide. These cancers have different causes, with smoking/tobacco exposure and human papilloma virus infection being the most common. . When HNSCC occurs in people who are not infected with HPV, the cancers are more likely to return after treatment; when this happens, overall survival is only about 10 months, thus better treatments are needed. Objective: To test a combination treatment using 2 drugs (valemetostat and pembrolizumab) in people with HNSCC. Phase 1b of the study will determine a recommended dose of the 2 drugs and evaluate how safe the combination is.; this will include patients with HPV-positive and HPV-negative HNSCC, as well as squamous cell NSCLC that have progressed on anti-PD-1/anti-PD-L1 therapies.Phase II will determine how effective the combination is and will focus on patients with HPV-negative HNSCC. Eligibility: People aged 18 years and older with HPV-negative HNSCC, sinonasal carcinoma of the head and neck, or squamous non-small cell lung cancer (NSCLC). Design: Participants will be screened. They will have a physical exam. They will have blood and urine tests and tests of their heart function. They will have imaging scans. They may have a biopsy: A small sample of tissue will be removed from the tumor. Treatment will be given in 21-day cycles. Pembrolizumab is administered through a tube attached to a needle inserted into a vein in the arm. Participants will receive pembrolizumab on the first day of each cycle. Valemetostat is a tablet taken by mouth. Participants will take the tablet once a day at home. They will record the date and time of each dose in a diary. They will also write down any adverse effects they experience. Participants may remain in the study up to 2 years.
This is a phase II study. Twenty-three patients with locally advanced head and neck squamous cell carcinoma were planned to be enrolled to assess the efficacy and safety of neoadjuvant immunotherapy combined with radiotherapy.
01.21 SiroSkin is a phase 3, double-blind, multi-centre, parallel-arm, randomised, placebo-controlled trial to evaluate the use of topical 1% sirolimus in the chemoprevention of skin cancer, versus placebo, applied every night for 6 months in solid organ transplant recipients.
Anal cancer can be prevented through detection and treatment of a recognised precancerous lesion, known as anal intra-epithelial neoplasia (AIN), specifically the anal high-grade squamous intra-epithelial lesion (aHSIL) subtype. Assessment of changes in disease burden is an important feature in the clinical evaluation of a treatment. Existing trials in aHSIL have predominantly used disease response outcomes based on histological and cytological changes to measure the effects of treatment. Several limitations to this approach have been identified. Lesion characteristics such as lesion size and number represent potential indicators of disease response to treatment and might overcome some of the limitations. We aim to develop a disease measurement instrument capable of describing disease burden such that it can be used to evaluate disease response to treatment in addition to histological and cytological based measurements further strengthening the quality of disease response outcomes. The disease measurement instrument will be developed over 4 stages: 1. A meeting of AIN experts to determine a longlist of lesion measurement items capable of capturing disease burden; 2. A series of disease assessments will be undertaken in participants known to have aHSIL to assess disease burden using the measurement items identified in stage 1; 3. Data analysis to determine the best performing measurement items and comprise a disease measurement instrument; 4. Pilot-testing of the proposed disease measurement instrument. Two trained disease assessors (experienced clinicians familiar with the assessment of anal intraepithelial lesions) will assess disease burden per participant. Disease burden will also be captured photographically. We will undertake disease assessments on 20-30 participants. By analysing the results of the clinician assessments and digital analysis of the photographic representation of disease burden, we will be able to determine the most acceptable, feasible, reliable and reproducible ways of measuring disease burden and use these to inform a disease measurement instrument.
The aim of this research is to decrease the number of inadequate tumor-free margins, probably resulting in less adjuvant therapy, less local recurrences and better quality of life.
To learn if TTI-101 can reduce the growth of HPV-negative squamous cell carcinomas of the head and neck when given before standard of care surgery.
In the current protocol, application of 3D ex-vivo ultrasound, MRI, and clinical evaluation (palpation and examination) by the surgeon is proposed to analyze the margin status in tongue squamous cell carcinoma and correlate the results to the histopathology findings.
Patients with locally recurrent squamous-cell carcinoma of the head and neck (SCCHN) after Chemotherapy and immunotherapy have a very poor prognosis and limited therapeutic options. Intratumoral chemotherapy (ITC) with cisplatin and epinephrine in order to increase the local cisplatin retention lead to a 50 % response rate in several studies but was given up due to the poor local tolerance with frequent necrosis of the peritumoral tissues. Gemcitabine, carboplatin and paclitaxel (GCP) are used in advanced SCCHN. These chemotherapies seem to be interesting options for intratumoral infusion: their different effect could lead to avoid chemotherapy resistance with a good tolerance profile, without tissue necrosis profile. The other major option for recurrent SCCHN is immunotherapy by Nivolumab, an anti PD-1 with a 13% mediane response rate. Nevertheless, the failure of this treatment stay unclear, but immunosuppressive action of the tumour is suspected. The presence of tumoral antigen could lead to better response to immunotherapy; association of chemotherapy and immunotherapy seems a promosing association to avoid treatment resistance as cytotoxic release tumoral antigen; it could also be associated to an abscopal effect. The aim of the study is to evaluate the efficacy of ITC using GCP in LOCAL recurrent SCCHN treated by nivolumab.
