AUR87A is an observational prospective multicenter diagnostics test cohort study for detection of renal cell carcinoma recurrence as determined by the reference standard, which is imaging using computed tomography (CT) of the chest and abdomen at defined intervals after primary surgery.

This phase I trial tests the safety, side effects, and best dose of ex vivo expanded natural killer cells in treating patients with cancerous (malignant) tumors affecting the upper part of the brain (supratentorial) that have come back (recurrent) or that are growing, spreading, or getting worse (progressive). Natural killer (NK) cells are immune cells that recognize and get rid of abnormal cells in the body, including tumor cells and cells infected by viruses. NK cells have been shown to kill different types of cancer, including brain tumors in laboratory settings. Giving NK cells from unrelated donors who are screened for optimal cell qualities and determined to be safe and healthy may be effective in treating supratentorial malignant brain tumors in children and young adults.

The purpose of this study is to evaluate the safety and effectiveness in the treatment of recurrent glioblastoma with Cadonilimab combined with fractionated radiotherapy.

In France, squamous cell carcinomas of the head and neck (SCCHN) are the 5th most common cancer. 60% of patients present with locally advanced tumors (stage III/IV), characterized by a poor prognosis (5-year survival not exceeding 60%). The standard treatment consists of either surgical removal followed by adjuvant radiochemotherapy or exclusive radiochemotherapy. In case of locoregional recurrence (about 40% of patients), salvage surgery can be proposed, allowing prolonged survival for less than one third of eligible patients. However, more than half of locoregional recurrences are unresectable. The standard treatment then consists of immunotherapy and/or chemotherapy for palliative purposes with a median survival of no more than 15 months. Stereotactic radiotherapy is another potentially curative option that allows a local control of 30-60% at 1 year, but at the cost of significant toxicity (up to 50% of grade 3-4 toxicities), thus limiting its indication. The issue of salvage treatment also applies to other rarer histological forms, including naso-sinus and salivary gland tumors, for which the probability of overall survival at 5 years does not exceed 65% due to locoregional evolution, despite advances in surgical techniques and the addition of radiotherapy. During the last two decades, minimally invasive interventional radiology techniques have been developed in the field of oncology. Among these techniques, cryotherapy is now commonly used for the treatment of several cancers. The multiplication of its indications is based on numerous clinical advantages (good post-operative analgesia, good toxicity profile, good tumor control). Cryotherapy could thus be a therapeutic alternative in head and neck cancers in recurrence situation in irradiated and unresectable territory, allowing to maintain a curative project in a higher proportion of patients and also to have a more favorable toxicity profile than re-irradiation.

ARES is a multicenter, single-arm, phase 2 trial to evaluate the efficacy and safety of ADT in combination with apalutamide as an adjuvant regimen for patients with high risk of recurrence after radical prostatectomy.

Hepatocellular carcinoma (HCC) is the 7th most common cancer worldwide but is the 4th deadliest, because diagnosis tend to be late and current systemic therapies are poorly efficacious. Within the same tumour, different parts of the HCC can belong to separate molecular sub-groups. In addition, there is currently no validated predictive biomarkers to help clinicians select the best therapy for an individual patient. This challenge poses an urgent, unmet clinical need. To address this, the multi-disciplinary research program Precision Medicine in Liver Cancer across an Asia-Pacific Network (PLANet 1.0) was conceptualized and successfully conducted from 2016-22. The program uncovered novel insights into the highly heterogeneous molecular landscape of HCC and novel mechanisms, including how HCC reverts to fetal forms to escape the body's immunological defence. These investigations will be continued in PLANet 2.0 and in this new phase, the research team will investigate patients receiving best-in-class therapeutics in 2 investigator-initiated clinical studies (AHCC12 and AHCC13), including Atezolizumab plus Bevacizumab (Atezo+Bev) and Yttrium-90, which allows the research team to collect longitudinal, before and after treatment biosamples and clinical data. These clinical studies will serve as proof-of-concept to the study team's translational findings and allow it to uncover predictive biomarkers which will help clinicians to institute more efficacious and personalized treatment in the future. The research team comprises of experts in different complementary fields (epigenomics, genomics, immunomics, metabolomics, proteomics, clinical science and data science) and across different institutions. This allows the team to adopt an integrative approach in understanding the landscape of the HCC tumour micro-environment and biomarkers co-localisation, and their role in tumour evolution and therapeutic response. By adopting a wide spectrum of converging investigations, PLANet 2.0 will identify and validate biomarkers that correlate with clinical outcomes (response, resistance and recurrence).

This is a Phase 1 study of recurrent glioblastoma locoregional adoptive therapy with autologous peripheral blood T cells lentivirally transduced to express a dual-target, truncated IL7Ra modified chimeric antigen receptor (CAR), delivered by Ommaya reservoir, a pre-indwelled catheter in the tumor resection cavity. Patients with recurrent glioblastoma will have surgical treatment and pathological test for target expression at their home institution or at Beijing Tiantan Hospital. If the tumor is target positive and the patient meets all other eligibility criteria, and meets none of the exclusion criteria, will have Ommaya reservoir implantation, and a subsequent Peripheral Blood Mononuclear Cells (PBMCs) collection. T cells will then be isolated from the PBMC sample and then be bioengineered in to a 4th generation CAR-T cell, Tris-CAR-T cells. Recipients with Ommaya reservoir implanted will be assigned to three courses. The first 2 patients will be assigned to low dose group, and will have one dose of autologous Tris-CAR-T cells delivery via Ommaya reservoir. The second 2 patients will be assigned to high dose group, and will have one dose of autologous Tris-CAR-T cells delivery via Ommaya reservoir. The last 4 patients will be assigned to multidose group, and will receive a weekly dose of autologous Tris-CAR-T cells for maximum 8 weeks. All patients will undergo studies including MRI to evaluate the effect of the CAR-T cells, physical examination and cerebrospinal fluid cytokine assays to evaluate side effects. All patients will undergo a long-term follow-up. The hypothesis is that an adequate amount of Tris-CAR-T cells can be manufactured to complete all the three courses. The other hypothesis is that Tris-CAR-T cells can safely and effectively be administered through Ommaya reservoir to allow the CAR-T cells to directly interact with the tumor cells for each patient enrolled on the study. The primary aim of the study will be to evaluate the safety of Tris-CAR-T administering. Secondary aims of the study will include to evaluate CAR-T cell distribution within cerebrospinal fluid and peripheral blood, tumor progress post CAR-T cell infusion, and, if tissues samples from multiple time points are available, also evaluate the degree of target expression, biological characteristics of samples at diagnosis versus at recurrence or progression.
