Active clinical trials for "Recurrence"

This is a single-arm open-label phase I/II study to determine the relative superiority of αCD19-TCRζ-CD28 and αCD19-TCRζ-CD137 CAR-T Cells in safety, efficacy and engraftment potential in patients with CD19+ B-lineage leukemia and lymphoma. Recently, cancer immunotherapy, treatments aiming to arm patients with immunity specifically against cancer cells, has emerged as a promising therapeutic strategy. Clinical trials utilizing CARs against B cell malignancies have demonstrated remarkable potential. In this trial, all subjects will be competitively infused with αCD19-TCRz-CD28 and αCD19-TCRz-CD137 CAR-T cells in equal number to test a hypothesis that CD137-costimulation can promote the persistence and engraftment of CAR-T cells and this superiority can lead to improved progression-free survival.

The goal of this clinical trial is to study the feasibility and efficacy of anti-CD22:TCRz:4-1BB chimeric antigen receptor (CAR)-modified T (CAR-T) cells in treating recurrent patients with refractory or resistant lymphoma to anti-CD19:TCRz:CD28 CAR-T cells. Recently, cancer immunotherapy, treatments aiming to arm patients with immunity specifically against cancer cells, has emerged as a promising therapeutic strategy. Among the many emerging immunotherapeutic approaches, clinical trials utilizing CARs against B cell malignancies have demonstrated remarkable potential. CARs combine the variable region of an antibody with T-cell signaling moieties to confer T-cell activation with the targeting specificity of an antibody. Thus, CARs are not MHC-restricted so they are not vulnerable to MHC down regulation by tumors. However, defined by the recession of evaluable lesions, the persistence and efficacy of CAR-T cells are still restricted by the "target" selection. Previous clinical studies largely utilized CD19 for the in vivo targeting of CAR-T cells, which preferentially become refractory or resistant due to the heterogeneity of lymphoma. This clinical investigation is to test a hypothesis whether anti-CD22 CAR-T cells work more effective in lymphoma patients refractory or resistent to anti-CD19:TCRz:CD28 CAR-T cells.

A randomized controlled, multi-center, open, phase II clinical study is designed to target patients with resectable intrahepatic cholangiocarcinoma with high-risk recurrence factors which has extremely low postoperative recurrence-free survival. In this study, we aim to compare the prognosis in intrahepatic cholangiocarcinoma between Toripalimab combined with Lenvatinib and GEMOX neoadjuvant treatment and the current clinical surgical treatment (traditional group).

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 efficacy of low-dose aspirin combined with low-molecular-weight heparin treatment for improving antiphospholipid syndrome and maternal-fetal outcome of patients is recognized by various countries and recommended by the guidelines. However, there are still 20-30% of APS patients whose treatment fails. Therefore, the standard treatment effect is still not ideal, and other treatment options need to be explored. The purpose of this study is to conduct a randomized double-blind, parallel controlled study of patients with recurrent miscarriage and APS in addition to standard treatment, plus hydroxychloroquine sulfate (HCQ) or placebo, to observe the effects of HCQ on pregnancy outcome in patients with abortion and APS, to evaluate the effectiveness and safety of HCQ treatment.

This is a single-arm and open-label study to assess the safety, tolerability and primary efficacy of the HBV specific T cell receptor (HBV/TCR) redirected T cell in patients with recurrent Hepatitis B virus (HBV) related hepatocellular carcinoma post liver transplantation.

This proposal aims to determine whether an adjunctive Mindfulness-Based Relapse Prevention (MBRP) treatment program improves Medication Assisted Treatment (MAT) adherence and reduces drug-use among opioid use disorder (OUD) patients. The broad long-term objectives of this project are to investigate how integrative pharmacological and behavioral treatments improve OUD treatment outcomes. Participants for this study will include 200 patients diagnosed with opioid use disorder (OUD), that are enrolled in a 60-day residential addiction treatment program and prescribed MAT for OUD. Participants will be randomly assigned to a MBRP behavioral treatment condition or a non-MBRP treatment-as-usual (TAU) control condition as part of their treatment within the residential addiction treatment program. All participants will be monitored for three-months following their discharge from the program to test the hypotheses that MBRP participants, relative to TAU participants, will (1) demonstrate greater MAT adherence following discharge, and (2) evidence reduced drug-use following discharge.

We aim to evaluate the feasibility and toxicity of testing the tolerance and immunogenic effects of high-dose SCART radiotherapy in patients with bulky metastatic or recurrent cancer in the setting of a single-arm phase I clinical trial. The primary endpoint of the study was to determine dose-limiting toxicities (DLT)s and the Maximum Tolerated Dose (MTD) of SCART to bulky metastatic or recurrent cancers.

Human epidermal growth factor receptor 2 (HER2) is overexpressed or amplified in 10-20% of gastric or gastroesophageal junction cancer. Trastuzumab combined with fluorouracil and platinum has been established as first-line treatment for patients with HER2-positive gastric cancer. The role of trastuzumab in second-line treatment for HER2-positive gastric cancer has not yet been addressed. Here, we evaluated the safety and efficacy of adding trastuzumab to ramucirumab and paclitaxel combination as a second-line treatment in HER2-positive gastric cancer progressed after trastuzumab-containing chemotherapy.

The objective of this study is to assess the safety, efficacy, pharmacokinetics, and immunogenicity of MRG003 in patients with recurrent or metastatic squamous cell carcinoma of head and neck.
