Filter by:This study is a single-arm, phase 2 trial of Geptanolimab in patients with initially unresectable, recurrent or metastatic ASPS. The study aims to study the activity of Geptanolimab assessed per RECIST 1.1 and iRECIST criteria, and safety profile.
The benefits of cancer treatments, such as chemotherapy, are traditionally measured by outcomes such as progression free survival and overall survival. The degree to which treatments affect symptoms of disease, patient functioning and HRQoL are rarely measured or incorporated in the main endpoints of large-scale clinical trials. Systemic treatments for the majority of patients with advanced STS are not curative but aim to improve patients' HRQoL through reduction of symptoms, slowing or halting disease progression, and may extend life for some patients. Despite this, there is little research into the impact of chemotherapy on HRQoL for advanced STS patients. In order for patients to make an informed decision about chemotherapy and the predicted effects on all aspects of their lives, clinicians should be able to provide data on HRQoL. This will also enhance the shared decision-making process between clinicians and their patients. Given that survival benefits of treatment beyond 2nd line chemotherapy are marginal, and HRQoL data are lacking for patients treated with third line systemic treatment, simultaneous collection of HRQoL data in patients treated with 1st and 3rd line chemotherapy will enable assessment of the course of HRQoL in patients at the beginning, and further along, their treatment trajectory. After discontinuation of 1st or 3rd line chemotherapy, all patients will be followed up at 2-3 month intervals to determine trajectory of quality of life over time, irrespective of whether or not they receive subsequent line(s) of chemotherapy.
This is a phase I, open-label, non-randomized study that will enroll pediatric and young adult research participants with relapsed or refractory non-CNS solid tumors to evaluate the safety, feasibility, and efficacy of administering T cell products derived from the research participant's blood that have been genetically modified to express a EGFR-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express EGFR and the selection-suicide marker EGFRt. EGFRt is a protein incorporated into the cell with our EGFR receptor which is used to identify the modified T cells and can be used as a tag that allows for elimination of the modified T cells if needed. On Arm A of the study, research participants will receive EGFR-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at EGFR and CD19, a marker on the surface of B lymphocytes, following the hypothesis that CD19+ B cells serving in their normal role as antigen presenting cells to T cells will promote the expansion and persistence of the CAR T cells. The CD19 receptor harbors a different selection-suicide marker, HERtG. The primary objectives of the study will be to determine the feasibility of manufacturing the cell products, the safety of the T cell product infusion, to determine the maximum tolerated dose of the CAR T cells products, to describe the full toxicity profile of each product, and determine the persistence of the modified cell in the subject's body on each arm. Subjects will receive a single dose of T cells comprised of two different subtypes of T cells (CD4 and CD8 T cells) felt to benefit one another once administered to the research participants for improved potential therapeutic effect. The secondary objectives of this protocol are to study the number of modified cells in the patients and the duration they continue to be at detectable levels. The investigators will also quantitate anti-tumor efficacy on each arm. Subjects who experience significant and potentially life-threatening toxicities (other than clinically manageable toxicities related to T cells working, called cytokine release syndrome) will receive infusions of cetuximab (an antibody commercially available that targets EGFRt) or trastuzumab (an antibody commercially available that targets HER2tG) to assess the ability of the EGFRt on the T cells to be an effective suicide mechanism for the elimination of the transferred T cell products.
This is a multicenter, open-label, Phase 1 study of orally administered VMD-928 in adult subjects with advanced solid tumors or lymphoma that have progressed or are non responsive to available therapies and for which no standard or available curative therapy exists
Up to 50% of soft tissue sarcoma (STS) patients will develop metastases in the course of their disease. Cytotoxic therapy is a standard treatment in this setting but yields average tumor response rates of 25% at first line and ≤10% at later lines. It is also limited in the number of lines and courses by tolerance issues. Trials include poly/oligometastases indistinctively and suggest that consolidation ablation is used in ~20% of patients with residual oligometastases refractory to chemotherapy. Oligometastases represent a stage of disease between completely absent and widely metastatic, and which might be cured if the limited numbers of metastatic sites are eradicated. Ablative strategies to treat patients with oligometastases from sarcomas yield prolonged survival times and stereotactic body radiation therapy (SBRT) is associated with excellent tolerance. Surgery may be offered in selected metastatic cases. Alternatively and increasingly, SBRT yields high control rates at treated sites (≥ 80%). The so-called radioresistance of sarcomas is overcome by the high doses per fraction made possible owing to the high precision achieved with SBRT. SBRT is an accepted treatment strategy provided that tumor burden remains limited in the number and size of metastases. Systemic treatment can be combined with SBRT. SBRT may produce abscopal effects where tumors outside the irradiation area also demonstrate tumor shrinkage in some occurrences. SBRT produces systemic antitumoral immune response in certain conditions and enhances radiation-induced tumor cell death compared to conventional lower dose irradiation. Abscopal effects have been potentialized with SBRT/immunotherapy in several tumor models. Sarcomas are a privileged target tumor given their high metastatic propensity. Several potent immunomodulators that skew the tumor immune microenvironment toward a proimmunity context are being investigated in STS either alone or in combination with chemotherapy or targeted therapy. The PD-1 receptor is present within the tumor microenvironment, and limits the activity of infiltrating cytotoxic T lymphocytes, thus blocking effective immune responses. The action of PD-1 is triggered upon binding to its ligands. PD-1 can stimulate the immunosuppressive function of regulatory T cells. Moreover, blockade of PD-1 can stimulate anti-tumor immune responses. Significant responses have been obtained in several sarcomas with acceptable tolerance. Preliminary clinical experience suggests that immunotherapy can be efficient in refractory leiomyosarcomas. Several drugs targeting the PD-1/PD-L1/2 axis are ongoing either as single agents or in combination with ipilimumab, kinase inhibitors, or chemotherapy in STS subtypes. Combination of radiotherapy with immunotherapy is included as a means of increasing tumor antigen release in metastatic STS. Immunomodulated SBRT is a particularly attractive strategy, given the potential of radiation to induce cytotoxicity in tumors and induce abscopal effects. A phase II radiation trial showed increased apoptosis-, intra-tumoral dendritic cells and accumulation of intratumoral T cells in STS with correlation with tumor-specific immune responses. We here propose a randomized phase II study to prolong progression-free survival (PFS) with the combination of SBRT/immunotherapy in oligometastatic STS patients. SBRT is well-tolerated with hardly any severe toxicity (fewer than 5% acute and late grade 3 toxicities). It is performed in an ambulatory setting in only a few treatment fractions. Associations between irradiation and immunomodulatory agents appear to be synergistic and show favorable tolerance profiles. Immunomodulatory agents have a more favorable toxicity profile than cytotoxic agents with about 65% overall acute toxicities. Immunotherapy selectively binds to PD-L1 and competitively blocks its interaction with PD-1. Compared with anti-PD-1 antibodies that target T-cells, immunotherapy targets tumor cells, and is therefore may induce fewer side effects, including a lower risk of autoimmune-related safety issues, as blockade of PD-L1 leaves the PD-L2 - PD-1 pathway intact to promote peripheral self-tolerance. Stereotactic irradiation is associated with an excellent tolerance with rates of grade 3 or more toxicities below 5%. Preliminary data of toxicity with the association of stereotactic irradiation and immunotherapy show no cumulative toxicity in association with immunotherapy. However, their incidence and characteristics are no different from that observed with stereotactic irradiation alone. Moreover, intracranial metastases are exceptional in sarcomas. The toxicity of the association for extracranial stereotactic irradiation does not seem to be increased either.
Assessment of the efficacy and safety of Regorafenib and Avelumab in patients with advanced or metastatic solid tumors (ten cohorts), once the Recommanded Phase II Dose (RP2D) has been determined (phase I trial). Assessement of the efficacy and safety of a low-dose of regorafenib (80mg/day) with avelumab in patients with advanced or metastatic colorectal tumors.
This multicentric, randomised, Phase II trial will use a pick-the-winner design in order to evaluate the clinical and biological activity of atezolizumab when combined with pre-operative or post-operative radiotherapy in STS patients. Following Inform Consent Form (ICF) signature, eligible patients will be randomised (1:1:1) to receive: - Arm A: Radiotherapy followed by atezolizumab then surgery. - Arm B: Atezolizumab followed by surgery then radiotherapy. - Arm C: Radiotherapy then surgery followed by atezolizumab. The sequence of the study treatments is different among the 3 study arms. However, the dose regimens will be the same: - Atezolizumab will be administered to all patients at the dose of 1200mg, by IV injection, for 2 cycles (Q3W). - Radiotherapy will be administered to all patients at the dose of 2Gy/day, 5 days per week, for a total of 5 weeks and 50Gy. - Surgery will be performed as per institutional practice. Randomisation will be stratified according to histological subtypes as follows: Group 1: Liposarcoma (LPS), Undifferentiated Pleomorphic Sarcoma (UPS), Leiomyosarcoma (LMS), myxofibrosarcoma, angiosarcoma versus Group 2: all translocation sarcoma except Ewing, rhabdomyosarcoma (RMS) and myxoid LPS.
Classic and endemic Kaposi's sarcoma (KS) are lymphangio-proliferations associated with human herpes virus 8 (HHV8), which treatment is poorly codified. Chemotherapies give at best 30-60% of transient responses. While interferon responses are frequent, this drug is often poorly tolerated in elderly patients. Therefore new therapies are needed. Classic KS represents an ideal model for evaluating new drugs since patients do not receive concomitant immunosuppressive regimens nor antiviral therapies. Pembrolizumab, an anti-PD1 monoclonal antibody has recently been shown to improve survival in several solid tumors. In KS few data are available on the role of PD1-PD-L1 axis. A significant PD-L1 expression on HHV8-associated pleural effusion lymphomas and on KS samples have been recently reported. Our experience in classical and endemic KS supports the role of this pathway with expression of PD-L1 by subpopulations of T cells but also NK cells in peripheral blood cells from these patients and expression of PD-L1 by tumor cells in KS lesions. In this study we will evaluate the benefit and safety profile of pembrolizumab in classic and endemic KS.
This research is being done to find out if an investigational drug, Nivolumab, can be safely administered after a "half-matched" (haplo) bone marrow transplant (BMT), and if the investigational drug will help to prevent or delay relapse or progression of sarcomas. In this study investigators will also be trying to learn more about how the investigational drug changes blood and/or tumors. Participants are eligible for this trial if they have recently undergone a "half-matched" (haplo) bone marrow transplant and have either relapsed or are at high risk to relapse.
The BCB is a tool: - for research in analytical and public health epidemiology, biological research and for the development of data useful for clinical research and therapeutic trials; - to help scientists understand and explain phenomena ranging from the interaction of molecules to the whole metabolism of the organism in normal and pathological situations; - to identify potential strategies for prevention, diagnosis, management and analysis of cancer subtypes. The creation of a broad clinical and biological prospective base dedicated to different types of cancer is essential for the development of such projects.
