Filter by:The goal of this clinical trial is to learn about the efficacy and safety of trastuzumab emtansine (T-DM1) in the treatment of patients with advanced HER2-positive breast cancer after TKIs or HP therapy. The main questions it aims to answer are: - The objective response rate of patients receiving T-DM1 therapy with advanced HER2-positive breast cancer after TKIs or HP therapy. - The adverse events and prognosis of patients with advanced HER2-positive breast cancer who receive the T-DM1 therapy. - Changes of anti-tumor immunity during T-DM1 therapy in patients with advanced HER2-positive breast cancer. Participants will receive T-DM1 treatment (3.6mg/kg, d1/21, IVD) until progressive diseases or intolerable adverse effects occurs.
This is an intervention study, aiming to use high and low dose radiotherapy combined with PD-1/PD-L1 inhibitor combined with GM-CSF to observe the effect of anti-tumor immunity and long-term therapeutic response rate, and to explore a new treatment model for patients with advanced solid tumors.
In preclinical research, short-term fasting (STF) protects tumor-bearing mice against the toxic effects of chemotherapy, improves the CD8+ effector T-cell intratumor infiltration, while enhancing the chemotherapy efficacy. Short-term use of a "fasting-mimicking diet" (FMD) caused a major increase in the efficacy of cancer treatment in mice comparable to STF. In humans, the investigators recently performed a multicenter randomized phase II trial showing that patients with Human Epidermal growth factor Receptor 2 (HER2) negative breast cancer treated with neoadjuvant chemotherapy and FMD displayed a better radiological response and a better pathological response (90-100% vs <90% tumor cell reduction) than patients treated with chemotherapy without FMD (de Groot, Nat Commun 2020; NCT02126449). Therefore these findings will be validated in a phase 3 trial with the underlying hypothesis that FMD during neoadjuvant chemotherapy for breast cancer improves clinical outcomes, potentially due to improved local immunity.
This study is a prospective, multicenter, phase II clinical trial to evaluate the efficacy and safety of albumin-bound paclitaxel plus bevacizumab for platinum-resistant recurrent epithelial ovarian cancer. Patients with platinum-resistant recurrent ovarian cancer who meet the inclusion criteria, and don't meet any of the exclusion criteria, are enrolled in the study. They will receive albumin-bound paclitaxel (260 mg/m2) and bevacizumab (7.5mg/kg) intravenously every 21 days. The total treatment periods are no more than 6 cycles. Treatment continue until disease progression, intolerable toxicity, or patient refusal. Objective response rates primary objective. Progression-free survival, overall survival, and safety are secondary objectives. The study will enroll a total of 50 patients.
To evaluate the efficacy and safety of CD19 PD-1/CD28-CAR-T sequential low-dose decitabine in the treatment of relapse or refractory B cell lymphoma.
The study is a multi-center, prospective, one-arm, phase II clinical trial. It is tend to examine the safety and efficacy of combining abraxane(albumin-bound paclitaxel） and bevacizumab to treat patients with recurrent, platinum-resistant primary epithelial ovarian cancer, fallopian tube cancer or peritoneal carcinoma.
Patients with recurrent or metastatic uterine cervical squamous carcinoma have very poor prognosis. For eligible patients, radiotherapy remains the choice, which has the most effective impact on the survival periods. On the hand, anti-angiogenic therapy has been proved to be promising treatment for recurrent or advanced cervical carcinomas. This study aims to discover the objective response of combination therapy with nimotuzumab (an anti-epidermal growth factor receptor [EGFR] IgG1 humanized monoclonal antibody) and radiotherapy in recurrent or metastatic uterine cervical squamous carcinoma in a single-arm, open, phase 2 clinical trial. The primary endpoint is the objective response rate evaluated by imaging methods. The second endpoints are the progression-free survival and overall survival. The treatment toxicity is regarded as one the second endpoint.
Recurrent or advanced cervical neuroendocrine carcinoma (NEC) is refractory to multimodal treatment, even to extensive therapy. Chemotherapy, consisting of platinum and etoposide, remains the main therapy for recurrent or advanced cervical NEC. In addition, bevacizumab has shown progression-free benefits in recurrent or advanced cervical cancer. Case report suggested anti-PD-1 antibody may have antitumor activities in NEC. Based on these evidences, a phase 2, single arm trial is conducted to explore the objective response rate (ORR) of platinum/etoposide/bevacizumab/anti-PD-1 antibody (camrelizumab) for the treatment of recurrent or advanced cervical NEC. This trial is to enroll 20 patients, who would accept 6 courses of platinum/etoposide/bevacizumab/camrelizumab. If the patient achieved complete or partial remission, a total period of 12 months bevacizumab/camrelizumab will be given as maintain therapy. The primary endpoint is ORR. The second endpoints are severe adverse events according to criteria of Common Terminology Criteria for Adverse Events (CTCAE) and iRECIST Guideline, and critical changes of laboratory testing.
The investigators design a large sample size study in the real-world to explore whether targeted therapy and immunotherapy can improve the survival, quality of life and drug safety of patients with advanced hepatobiliary tumors, and analyze the correlation between genetic variation and the effectiveness of therapy.
