Filter by:Esophageal cancer (EC) is one of the most common malignant tumors of the digestive tract in human beings. Most cases of EC are initially diagnosed in an advanced stage of the disease. Considering the lack of effective adjuvant therapies after surgery for locally advanced esophageal squamous carcinoma. And with the encouraging preliminary results of PD-1 inhibitors in advanced esophageal squamous cell carcinoma (ESCC), postoperative adjuvant immunotherapy for esophageal squamous carcinoma seems to be feasible. The main objective of this study was the efficacy of postoperative adjuvant therapy with sintilimab in patients with ESCC radically resected after neoadjuvant chemoimmunotherapy.
Background: Squamous cell carcinoma is a type of cancer that can cause tumors on the head and neck (HNSCC). Even with treatment, less than 50% of people with certain types of HNSCC survive for 5 years. Objective: To test a new drug treatment (N-803 and pembrolizumab, with or without PD-L1 t-haNK cells) in people with HNSCC. These drugs may help the immune system to fight cancer. Eligibility: People aged 18 years and older who have HNSCC that is not linked to human papillomavirus infection. They must not yet have received any treatment and be scheduled for surgery to remove the tumors. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have imaging scans and a test of their heart function. They will have a biopsy: A sample of tissue will be removed from the tumor. Pembrolizumab is given through a tube attached to a needle inserted into a vein in the arm (intravenous infusion). N-803 is injected under the skin of the abdomen. All participants will receive these 2 treatments on day 1. They will have follow-up visits on days 8 and 15. Some participants will also receive PD-L1 t-haNK cells by intravenous infusion. These are cells that attack cancer cells. These participants will receive this treatment on days 1, 5, 8, 12, and 15. All participants will have a clinic visit on day 21. They will have a second biopsy. Follow-up visits will occur on days 49 and 105. Visits will continue by phone or email every 9 weeks for 2 years....
Background: Rare tumors of the genitourinary (GU) tract can appear in the kidney, bladder, ureters, and penis. Rare tumors are difficult to study because there are not enough people to conduct large trials for new treatments. Two drugs-sacituzumab govitecan (SG) and atezolizumab-are each approved to treat other cancers. Researchers want to find out if the two drugs used together can help people with GU. Objective: To test SG, either alone or combined with atezolizumab, in people with rare GU tumors. Eligibility: Adults aged 18 years and older with rare GU tumors. These may include small cell carcinoma of the bladder; squamous cell carcinoma of the bladder; primary adenocarcinoma of the bladder; renal medullary carcinoma; or squamous cell carcinoma of the penis. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have tests of heart function. They will have imaging scans. They may need a biopsy: A small needle will be used to remove a sample of tissue from the tumor. Both SG and atezolizumab are given through a tube attached to a needle inserted into a vein in the arm. All participants will receive SG on days 1 and 8 of each 21-day treatment cycle. Some participants will also receive atezolizumab on day 1 of each cycle. Blood and urine tests, imaging scans, and other exams will be repeated during study visits. Treatment may continue for up to 5 years. Follow-up visits will continue for 5 more years.
Prospective, open-label, phase 1 study of CD40 agonist (LVGN7409) and PD-1 inhibition (LVGN3616) in patients with resectable Human Papillomavirus (HPV)-negative mucosal head/neck squamous cell carcinoma (HNSCC). This protocol proposes to study the safety and immunological effects of LVGN7409, a CD40 agonistic antibody, when administered in combination with PD-1 inhibition prior to surgical resection.
This study is aimed to evaluate the efficacy and safety of sintilimab combined with chemotherapy versus chemotherapy in perioperative treatment of locally advanced esophageal squamous cell carcinoma.
A randomized, prospective phase II trial was conducted to explore the timing of radiotherapy intervention in combination with chemotherapy and immunotherap in order to provide an effective treatment for patients with advanced esophageal squamous carcinoma with oligometastases.
ELOS is a prospective, randomized, open-label, controlled, two-armed parallel group, phase II multicentre trial in local advanced stage III, IVA/B head and neck squamous cell carcinoma of the larynx or hypopharynx (LHNSCC) with PD-L1-expression within tumor tissue biopsy, calculated as CPS ≥ 1 curable by total laryngectomy. Induction chemotherapy (IC) with Docetaxel and Cisplatin (TP) followed by radiation will be compared to additional PD-1 inhibition. Patients will be selected after short induction early response evaluation after the first cycle IC (IC-1) aiming on larynx organ-preservation by additional 2 cycles IC followed by radiotherapy (69.6 Gy) for responders achieving endoscopic estimated tumor surface shrinkage (ETSS) ≥ 30%. Nonresponders (ETSS < 30% or progressing disease) will receive total laryngectomy and selective neck dissection followed by postoperative radiation or chemoradiation according to the recommendation of the clinics multidisciplinary tumor board. However, Patients randomized into the intervention arm starting day 1 will receive 200 mg Pembrolizumab (MK-3475) i.v. in 3-week cycle (q3w) for 17 cycles (12 months). Treatment with pembrolizumab will continue in the experimental arm regardless of ETSS status after IC-1 in both responders and laryngectomized nonresponders, independent from subsequent decision on adjuvant therapy after TL.
The study is a multicenter, open-label, phase Ib/II study to evaluate the efficacy and safety of docetaxel for injection (albumin-bound) (HB1801) and SG001 in combination with cisplatin and simultaneous radiotherapy versus paclitaxel in combination with cisplatin and simultaneous radiotherapy for locally advanced unresectable esophageal squamous carcinoma.
Given the feasibility of induction chemotherapy in oral cancer and the encouraging remission rates achieved, we explore the clinical application prospects of using tislelizumab in combination with traditional standard chemotherapy as induction treatment in oral cancer patients who have no radiological evidence of mandibular erosion but require mandibulectomy due to the tumor's proximity to the mandible, aiming to shrink tumor size and increase the rate of mandible preservation. Therefore, we propose to conduct a prospective, single-arm, single-center phase II exploratory clinical trial: we plan to select patients with locally advanced resectable primary oral squamous cell carcinoma T3-4N0-3M0 (stages III-IVb, excluding T1-2) after multidisciplinary consultation and assessment by imaging and clinical evaluation. We aim to explore the feasibility of a three-week treatment regimen combining tislelizumab with polyaletin paclitaxel and a platinum-based triplet, preliminarily assess its clinical efficacy, adverse reactions, and postoperative mandible preservation rate, to provide the best comprehensive treatment plan for the preservation rate of the mandible in oral squamous cell carcinoma.
The goal of this clinical trial is to learn about the efficacy and safety of pablizumab combined with neoadjuvant chemotherapy in patients with locally advanced head and neck squamous cell carcinoma. The main question it aims to answer is: Pathological complete remission (PCR) rate of tumor after neoadjuvant immunotherapy. Participants will be asked to perform CT and MRI of head and neck, ultrasonography of cervical lymph nodes and necessary laboratory examinations Before and after neoadjuvant therapy. And will be following-up for at least 1 year.
