Clinical trials

Glutamine is a crucial nutrient for cancer cell growth, and its metabolism is frequently dysregulated in malignancies. 18F-FGln is a PET tracer that targets this altered glutamine metabolism. However, there are currently limited studies on the diagnostic value of 18F-FGln PET/CT in various types of cancer. Therefore, this prospective study was conducted to investigate the value of 18F-FGln PET/CT in patients with various types of malignant tumors.

Ovarian cancer is one of the most common gynecologic malignancies, with considerable histologic heterogeneity; more than 90 % of cases are epithelial ovarian cancers. Because no reliable tools exist for early detection, approximately 70 % of patients are diagnosed at an advanced stage and have poor prognosis, and \>70 % experience relapse within 3 years of initial treatment. The standard first-line strategy combines cytoreductive surgery, platinum-based chemotherapy, and maintenance with PARP inhibitors. Management of recurrent disease remains one of the most challenging problems in clinical oncology. Bevacizumab, a recombinant humanized anti-VEGF monoclonal antibody that blocks endothelial proliferation and neovascularization, is the prototypic angiogenesis inhibitor used in ovarian cancer. However, randomized trials have demonstrated only progression-free survival (PFS) benefit, with no overall survival (OS) advantage. Pre-clinical data suggest that immunotherapy and anti-angiogenic agents can exert synergistic anti-tumor activity, yet clinical efforts combining bevacizumab with immune-checkpoint inhibitors in recurrent ovarian cancer-whether added to platinum-based chemotherapy, used as maintenance, or evaluated in chemotherapy-free regimens-have thus far been unsuccessful (except in clear-cell histology). Anlotinib is a novel oral multi-target tyrosine-kinase inhibitor that blocks VEGFR-2/3, FGFR 1-4, PDGFR-α/β, c-KIT, and RET, thereby potently suppressing angiogenesis. Accumulating evidence indicates that anlotinib plus chemotherapy is more effective than chemotherapy alone in advanced or recurrent ovarian cancer, with a manageable safety profile, showing encouraging efficacy and tolerability. Because conventional approaches for recurrent ovarian cancer are limited-particularly once platinum resistance develops-new therapeutic strategies are urgently needed. The best-characterized immune-checkpoint molecules are CTLA-4 and the PD-1/PD-L1 axis. Combined blockade of CTLA-4 and PD-1 has yielded impressive activity in several tumor types. Although single-agent checkpoint inhibitors produce modest response rates in recurrent ovarian cancer, preliminary data suggest that dual inhibition with anti-CTLA-4 plus anti-PD-1 antibodies may enhance therapeutic responses.QL1706 is a novel dual-target immunotherapeutic agent that has been approved for second-line monotherapy in cervical cancer.QL1706, developed by Qilu Pharmaceutical using the proprietary MabPair™ platform, is the first bispecific antibody simultaneously targeting PD-1 and CTLA-4, showing synergistic anti-tumor activity and favorable tolerability.The treatment of recurrent ovarian cancer remains a formidable challenge; therefore, proactive exploration of diverse combination regimens is essential to achieve optimal therapeutic efficacy and maximize survival benefit for patients.

Cervical cancer ranks as the second most common malignancy of the female genital tract. According to the World Health Organization, there are 530,000 new cases and approximately 250,000 cervical-cancer-related deaths worldwide each year, with 80% of these deaths occurring in women from developing countries. Early-stage disease can be managed surgically, whereas advanced or recurrent cervical cancer is treated with individualized multimodal therapy; nevertheless, the optimal management of locally advanced cervical cancer (FIGO 2018 stage IB3-IIA2) remains controversial. Chemoradiation is standard, but neoadjuvant chemotherapy followed by radical surgery after tumor down-staging is also used. More than 90% of cervical cancers are driven by persistent infection with high-risk human papillomavirus (HPV), which evades host immunity in part by up-regulating PD-L1 on tumor cells. Published series report PD-L1 positivity in 34.4-96% of cervical cancers, with even higher rates in squamous-cell histology, providing a rationale for PD-1/PD-L1 blockade. QL1706, a novel bispecific immunotherapeutic agent, has recently been approved as monotherapy for second-line treatment of advanced cervical cancer.QL1706, developed by Qilu Pharmaceutical using the proprietary MabPair™ platform, is the first bispecific antibody simultaneously targeting PD-1 and CTLA-4, showing synergistic anti-tumor activity and favorable tolerability.Unlike previous phase II/III trials of PD-1 monotherapy, this study does not restrict enrolment to patients with PD-L1-positive tumors, so QL1706 is expected to confer benefit in the second-line management of recurrent or metastatic cervical cancer. Therefore, investigating QL1706-based combination regimens as neoadjuvant treatment for treatment-naïve disease is also highly relevant and may improve outcomes in women with locally advanced cervical cancer.

This clinical trial aims to evaluate the efficacy of early intervention with Memantine and Pioglitazone in preventing Radiation-Induced Brain Injury (RIBI) in patients undergoing cranial radiotherapy. RIBI, a significant complication of radiation therapy for primary and metastatic brain tumors, as well as head and neck cancers, often presents with delayed and irreversible neurological damage, severely affecting patients' quality of life. Our previous studies have indicated that Memantine, an NMDAR antagonist, and Pioglitazone, a PPAR-γ agonist, play crucial roles in modulating the neuroprotective immune microenvironment by targeting key mechanisms of neuron-astrocyte fatty acid metabolism coupling. These findings suggest that early administration of these drugs could protect cognitive function and reduce neuroinflammation in patients post-radiation. This prospective phase II clinical trial will assess the combined efficacy of Memantine and Pioglitazone in improving cognitive outcomes and preventing RIBI without adversely impacting the anti-tumor efficacy of radiation therapy. The study will also explore the synergistic effects of these two FDA-approved drugs in early-stage RIBI prevention, providing a new therapeutic strategy for enhancing the quality of life in cancer patients receiving radiotherapy.

Investigators have designed a randomized controlled trial. Utilizing an open-label, randomized, controlled study methodology, this trial aims to explore a opioid-free, safe, and effective analgesic approach for thoracic surgery. It also seeks to provide clinical guidance for the implementation of opioid-free or reduced-opioid postoperative analgesia in other thoracic procedures, aiming to optimize postoperative pain management for patients and ultimately enhance the overall patients recovery experience.

The purpose of this study is to determine the efficacy and safety of Hyperthermic Intravesical Chemotherapy (HIVEC) with Gemcitabine (GEM) after Transurethral Resection of Bladder Tumors (TURBT) in the treatment of medium or high-risk group Non-Muscle-Invasive Bladder Cancer (NMIBC).

To evaluate the Safety and Efficacy of HIPEC Combined With Sintilimab for Gastric Cancer Patients with Peritoneal Metastasis.

A single-center, observational study, integrated biomarker analysis of HIPEC combined Programmed cell death 1 /Programmed cell death 1 ligand 1(PD1/PDL1)inhibitor in previously treated patients of advanced gastric cancer with peritoneal metastasis. Tests will be performed on tumor tissue and blood samples, and imaging assessments will be reviewed in order to monitor how well each patient responds to treatment. This is an observational study, so participants will not receive cancer treatment, other than the treatment received as standard of care.
