Immune Checkpoint Inhibitors

Lattice radiation therapy (LRT) is a spatially fractionated thoracic radiotherapy technique that creates alternating high- and low-dose regions within primary lung tumors and metastatic lymph nodes to strengthen local tumor suppression and reduce radiation injury to normal thoracic organs. This study aims to evaluate the efficacy and safety of combining LRT with consolidation chemoimmunotherapy in unresectable stage III LA-NSCLC patients who show suboptimal tumor response to prior neoadjuvant chemoimmunotherapy, through a single-arm Phase II clinical trial. Patients will receive thoracic LRT delivered by a medical linear accelerator. High-dose spherical sub-targets will be contoured within the gross tumor volume of primary lung lesions and regional nodal metastases under standardized dose constraints to spare the lung, heart and esophagus. All enrolled subjects will receive sequential consolidation chemoimmunotherapy administered within one week after finishing LRT. Tumor response, treatment-related adverse events, local tumor control and long-term survival outcomes will be prospectively tracked throughout treatment and long-term follow-up.

The Phase IIIb NIAGARA-2 study aims to expand on the data from the Phase III NIAGARA study by investigating perioperative durvalumab in combination with investigator-selected cisplatin-based neoadjuvant chemotherapy (either ddMVAC or gemcitabine/cisplatin) in a clinical practice setting.

This prospective, single-arm, open-label study aims to evaluate the efficacy and safety of a PD-1 inhibitor (Sintilimab) combined with standard anti-infective therapy in patients with advanced HIV disease (AHD) who are suffering from refractory opportunistic infections (OIs). Despite effective antiretroviral therapy (ART), some HIV patients develop severe, hard-to-treat infections (such as CMV, PCP, Tuberculosis, etc.) that do not respond to standard antimicrobial treatments. This is often due to a condition called "immune exhaustion," where the body's infection-fighting T-cells become inactive and express high levels of a protein called PD-1. Sintilimab is an immune checkpoint inhibitor that blocks PD-1, effectively "waking up" the exhausted T-cells. While traditionally used for cancer, recent evidence suggests it can safely restore the immune system's ability to clear stubborn infections in HIV patients. In this study, eligible patients with refractory OIs and evidence of immune exhaustion will receive Sintilimab (200 mg intravenously every 3 weeks for a total of 3 doses) alongside their regular treatments. Researchers will monitor patient safety, clinical improvement, and immunological recovery.

This is a multicenter, double-blind, randomized, phase 2 trial to investigate the efficacy and safety of serlulimab combined with nab-paclitaxel plus SOX versus nab-paclitaxel plus SOX alone as neoadjuvant treatment for locally advanced GC or AEG. The goal of this clinical trial is to learn if serlulimab combined with nab-paclitaxel plus SOX as neoadjuvant treatment for locally advanced AEG/GC. It will also learn about the safety of serlulimab combined with nab-paclitaxel plus SOX. The main questions it aims to answer are: Does serlulimab increase the pCR of participants with locally advanced AEG/GC ? What medical problems do participants have when taking serlulimab? Researchers will compare to a placebo (a look-alike substance that contains no drug) to see if serlulimab combined with nab-paclitaxel plus SOX as neoadjuvant treatment for locally advanced AEG/GC. Participants will: Eligible patients were randomly assigned to receive serlulimab (4.5 mg intravenously on day 1) combined with chemotherapy (nap-paclitaxel 260 mg/m2 intravenously on days 1, OXA 130mg/ /m2, intravenously on days 1, and S-1 40 to 60 mg orally twice daily depending on BSA on days 1 to 14) or chemotherapy alone every 3 weeks for 3 preoperative cycles followed by 3 postoperative cycles. All patients will be followed for survival.

To understand the severity and nature of participants experiences during irAEs following immune checkpoint inhibitor immunotherapy.

This research team intends to conduct a real-world cohort study of chronic CNS viral infections represented by PML, to evaluate whether administration of immune checkpoint inhibitors improves long-term outcomes in this patient population.Patients with prior follow-up will be enrolled into a retrospective/prospective ambidirectional cohort, and newly diagnosed patients will be enrolled into a prospective cohort.

Iparomlimab and Tuvonralimab Injection (QL1706) is a bifunctional combination antibody targeting both programmed cell death protein 1 (PD-1) and cytotoxic T-lymphocyte antigen 4 (CTLA-4). This is a prospective clinical study that plans to enroll screened, eligible early-stage breast-cancer patients to receive neoadjuvant QL1706 plus chemotherapy (four cycles of TP ± four cycles of AC). After the four TP cycles, imaging and core biopsy will be performed. Patients who achieve radiologic complete response will proceed directly to surgery; those who do not will receive four additional AC cycles before surgery. A key feature is the incorporation of an response-guided neoadjuvant therapy（RGN）model to identify sensitive patients who can forgo anthracyclines, thereby reducing long-term cardiotoxicity.

This trial is a single-arm exploratory phase II clinical study initiated by the investigator. Subjects who met the research criteria were screened and enrolled to receive the treatment regimen of disitamab vedotin combined with lenvatinib and PD-1 inhibitor. During the treatment process, the researchers closely followed up, strictly evaluated the efficacy, assessed the efficacy and safety of the subjects after receiving the combined treatment, evaluated the subjects until progression occurred, and observed their objective response rate, progression-free survival, overall survival, disease control rate, duration of response, and safety evaluation.

Building on earlier exploratory work, this study further designs a multi-institutional, prospective, randomized clinical trial to evaluate the efficacy and safety of the combination therapy of the immune checkpoint inhibitor Tislelizumab with CAPOX for neoadjuvant treatment in high-risk locally advanced MSS-type colorectal cancer, as well as its impact on patient outcomes. This study aims to provide new evidence for the clinical practice of treating MSS-type colorectal cancer.

Nivolumab (and other agents affecting the anti-programmed death-1 \[anti-PD-1\] pathway) have demonstrated anti-tumor activity in multiple tumor types. Combinations of immune-oncology (IO) agents with complimentary mechanisms as well as radiation represent a promising strategy to improve response rates to immunotherapy and overcome resistance. In this phase I/Ib study, radiation will be used in combination with IO agents nivolumab and anti-IL-8 (BMS-986253) to assess toxicity by organ system and then assess the preliminary efficacy of the treatment regimen. In Part 1, the study will determine the safe doses of radiation by organ site in conjunction with nivolumab and BMS-986253. In Part 2, the treatment regimen will be investigated in melanoma, prioritizing acral melanoma, to describe the response rate to treatment as well as other clinical and safety outcomes. The study will also provide the opportunity to evaluate changes in the tumor microenvironment induced by the treatment.

Postoperative immunoadjuvant therapy has been proven to significantly reduce the risk of recurrence after resectable NSCLC, and has become a new standard of postoperative adjuvant therapy for stage II-III NSCLC. Immunotherapy faces challenges such as immune resistance, heterogeneity of biomarker expression, and limitation of immune-suitable population. How to reduce the rate of recurrence and metastasis after surgery, enhance the therapeutic effect of immunotherapy, and then prolong the survival period and improve the quality of life, has become an urgent problem facing the current clinical. Based on the standards of evidence-based medicine, this study for the first time carried out a large sample, multi-center, randomized parallel controlled clinical study to obtain high-quality clinical evidence of the effectiveness and safety of electro-acupuncture and Zilongjin tablet synergic treatment, and formed a standard treatment plan of traditional Chinese medicine.

In the last decades, cancer treatment was based on surgery, radiotherapy and chemotherapy. Recently, treatments have largely evolved, first with targeted therapies (notably tyrosin kinase inhibitors, TKI) and then with immune checkpoint inhibitors (ICPI, notably anti-CTLA-4 and anti- PD1). The last ones can induce durable anti-tumoral responses in patients, even if metastases are present. Their mechanisms of action are focused on the activation of immune system in order to eliminate the tumor. ICPI, because of their mechanisms of action, target immune tolerance key components and can induce important immune toxicities (colitis, hepatitis, dermatitis, thyroiditis ...), leading to early discontinuation of treatment, severe or chronic morbidity, and can sometimes be lethal. It is of importance to detect patient at risk of irAEs, because of the increasing use of ICPI and the long- term response capacity in treated patients.

This is the prospective, observational cohort study (Nezha) to explore the associations of sleep disturbance with progression, efficacy of immune checkpoint inhibitors (ICIs) and prognosis of Lung Cancer. The participants including the patients diagnosed with advanced non-small-cell lung cancer (NSCLC) who received either first-line therapy (ICIs or targeted agents) or neoadjuvant therapy with ICIs; patients diagnosed with advanced small-cell lung cancer (SCLC) receiving the first-line therapy ICIs; patients diagnosed with early non-small-cell lung cancer (NSCLC) receiving surgery.

This is the prospective, observational cohort study (STRESS-LUNG) to explore the associations of psychological stress with progression, efficacy of immune checkpoint inhibitors (ICIs) and prognosis of Lung Cancer. The participants including the patients diagnosed with advanced non-small-cell lung cancer (NSCLC) who received the first-line therapy or neoadjuvant therapy of ICIs; patients diagnosed with advanced small-cell lung cancer (SCLC) receiving the first-line therapy ICIs; patients diagnosed with early small-cell lung cancer (SCLC) receiving surgery.

Nowadays, there are few second-line treatment options for advanced hepatocellular carcinoma (HCC). In order to further improve the efficacy of second-line treatment for advanced HCC, we plan to conduct a phase II clinical study to explore the efficacy and safety of the new second-line treatment for advanced HCC. As a tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor -1/2/3 (VEGFR 1/2/3), fruquintinib had demonstrated a strong antitumor efficacy in colorectal cancer patients who had previously received standard chemotherapy. Compared with placebo, fuquinitinib significantly extended overall survival in patients with metastatic colorectal cancer (median OS, 9.3 months vs 6.6 months; HR, 0.65; p\<0.001) and progression-free survival (median PFS, 3.7 months vs 1.8 months; HR, 0.26; p\<0.001). Additionally, a phase II clinical study had showed that sintilimab combined with fruquintinib was with a promising anti-tumor activity in patients with advanced HCC who had received standard treatment, with a median PFS of 7.4 months and a tumor response rate of 31.6%. Therefore, we intend to conduct this clinical study to explore the efficacy and safety of fruquintinib as second-line treatment for patients with unresectable HCC previously treated with immune checkpoint inhibitors.

Study Objective: To determine the efficacy of upfront immune checkpoint inhibitors combined with deferred cytoreductive nephrectomy in treating metastatic renal cell carcinoma. Primary Endpoint: Pathological Major Response (MPR), defined as the percentage of residual tumor cells \<10% in the primary tumor after nephrectomy.
