This is a first in human, Phase 0/1, open-label study of 177Lu-RAD204 consisting of an Imaging Period with 177Lu-RAD204im (imaging dose) and a Treatment Period with 177Lu-RAD204tr (treatment dose) to determine the recommended dose(s) for future exploration of 177Lu-RAD204 in participants with PDL1+ advanced solid tumors. Screening Period: Screening Period of up to 4 weeks. Phase 0 (Imaging Period): Low dose (10mCi) of 177Lu-RAD204 administered on Imaging Day 1 with a follow-up period of up to 2 weeks to assess imaging, safety and dosimetry. The dose may be increased, if needed, to improve image quality. Phase 1 (treatment Period): 177Lu-RAD204tr dose escalation * Treatment Period with each cycle lasting 6 weeks. Extension of the planned dose intervals are possible following discussion and agreement between the Sponsor and Investigator. * Participants may be treated with multiple cycles, as long as they appear to derive clinical benefit as determined by the Investigator and provided there is adequate clinical safety and organ dosimetry data. * Dose Limiting Toxicity (DLT) observation period for 177Lu-RAD204tr is 6 weeks following the first injection of 177Lu-RAD204tr. * Should an alternative treatment schedule be explored, the DLT observation period for 177Lu-RAD204tr at that dose level will be the proposed cycle duration.

Participants with cancer underwent 68Ga-NK224 PET/CT for an initial assessment. Tumor uptake was quantified by the maximum standard uptake value (SUVmax) and mean SUV (SUVmean). In addition, the PD-L1 expression of lesions was confirmed by histopathological analyzing. The quantitative parameters of 68Ga-NK224 PET/CT were compared with histopathological result to evaluate the diagnostic efficacy.

Gastric cancer is the fifth most common cancer in the world and ranks fourth in mortality. Radical surgery is the main treatment for resectable gastric cancer. For patients with progressive gastric cancer, especially those with stage IIIB and IIIC, their 5-year overall survival (OS) rate after radical surgery is still difficult to exceed 50%. Although D2 radical surgery and postoperative adjuvant chemotherapy have significantly improved the prognosis of patients with progressive gastric cancer, the recurrence rate is still as high as 50%\~80%. Several therapeutic approaches have been established to reduce the risk of recurrence and improve long-term survival, including perioperative chemotherapy, adjuvant chemotherapy, and adjuvant radiotherapy. The effect of adding targeted therapies and/or immune checkpoint inhibitors (ICIs) to neoadjuvant/adjuvant therapies is currently being studied. While multiple programmed death 1 (PD-1) inhibitors have been approved for first/third line treatment of unresectable/metastatic gastric cancer. However, the role of immune checkpoint inhibitors in resectable gastric cancer remains unclear and is being investigated in various clinical trials. We conducted this study with 8 cycles of perioperative treatment with adebrelimab in combination with XELOX chemotherapy regimen and adebelizumab maintenance therapy up to 1 year. To observe and evaluate the efficacy and safety of adebrelimab combination chemotherapy regimen in the perioperative treatment of surgically resectable gastric cancer/adenocarcinoma of the gastroesophageal junction.

The Episwitch CiRT® (Checkpoint inhibitor Response Test) predicts how a patient will respond to immune checkpoint inhibitor (ICI) therapies by delivering a binary response likelihood profile (High Probability vs. Low Probability). Patients who have been diagnosed with stage III and IV cancer and who are candidates and/or planned to receive immune check point inhibitors as a therapy now or in near future will be offered the Episwitch CiRT™ before starting treatment or if on active treatment. Those patients with high probability of response to ICI will undergo repeat testing every three months. Patients will be followed for up to six months. Treatment administered, disease-free survival, overall survival, stable disease, progressive disease, complete response, time to recurrence, physician questionnaires and patient-reported outcomes will be recorded for six months. Comprehensive data of Social Determinants of Health (SDoH) will be collected to identify any correlation to unmet Health Related Social Needs (HrSN) and likelihood to response and/or resistance

Systemic therapy is the standard treatment for advanced hepatocellular carcinoma (HCC) with metastasis. However, metastases with limited number (oligometastasis) can represent a subtype and transition point between localized disease and widespread metastases. Thus, eliminating metastases could be advantageous and beneficial to the prognosis if feasible and permitted. Image-guided ablation therapy, such as microwave ablation (MWA), radiofrequency ablation (RFA), and cryoablation, has attracted great interest as a minimally invasive approach against intrathoracic metastases. Recently, ablation has been used on patients with pulmonary metastases from various cancers. This technique yields high proportions of sustained complete responses and is associated with relatively low morbidity. Thus, we conduct this multicenter single arm study to explore the efficacy, safety of lenvatinib and PD-1 inhibitor with metastases-directed ablation in advanced HCC. This study focuses on the management of ablation of oligometastasis therapy combined with lenvatinib and PD-1 inhibitor. This study aims to evaluate the survival benefits of ablating oligometastasis for advanced HCC.

Anlotinib is a new, orally administered tyrosine kinase inhibitor that targets vascular endothelial growth factor receptor (VEGFR), fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptors (PDGFR), and c-kit. Toripalimab is a humanized immunoglobulin (Ig) G4 monoclonal antibody directed against the negative immunoregulatory human cell surface receptor programmed cell death 1 (programmed death-1; PD-1), with potential immune checkpoint inhibitory and antineoplastic activities. In the present study, we design a single-arm, single center Phase II trial to evaluate the efficacy and safety of the combination of Anlotinib wiht Toripalimab in advanced gastric cancer with ECOG 2 as first-line treatment.

The innovative invention of Tumour Treatment Vaccine (TTV) has been verified in previous studies that the TTV vaccine can play a good role in enhancing the anti-tumour effect of immune checkpoint inhibitor therapy, and the tumour suppression rate of combined anti-PD-1 inhibitor reaches 75.96%. Therefore, this study is intended to investigate the clinical efficacy of TTV vaccine combined with PD-1/PD-L1 inhibitor in the treatment of relapsed and refractory advanced solid tumours from a clinical perspective.

This single-arm Phase II study aims to explore the safety and efficacy of concurrent chemoradiotherapy combined with toripalimab and surufatinib in treating LS-SCLC. In this single-arm, Phase II study, patients are planned to receive four cycles of etoposide combined with either cisplatin or carboplatin, along with toripalimab and surufatinib. During chemotherapy, patients will undergo concurrent radiotherapy. Following chemoradiotherapy, consolidation treatment with toripalimab and surufatinib will be administered. Prophylactic cranial irradiation (PCI) is recommended prior to the consolidation therapy.

Patients diagnosed with locally advanced nasopharyngeal carcinoma will be recruited in this study. All the patients will get 3 cycles of GP+ Envafolimab for the induction chemotherapy. After that, the patients will receive concurrent chemoradiotherapy. Radiotherapy will be given by IMRT, under the dose of GTVnx 68-70Gy/30-33f, 5d/w,6-7w, during which, every patient would receive 2 cycles of DDP+Envafolimab as concurrent chemotherapy. Then patients would receive Envafolimab every 3 weeks for maintenance treatment for a year, until disease progression or intolerance of treatment. . We aim to evaluate the three years progression free survival of these patients by the combination of Envafolimab with curative chemoradiotherapy.
