Clinical trials

This is a single-center, non-randomized feasibility study. For this study, 19 young adults treated for cancer at the Paoli-Calmettes Institute will be included.This study includes interviews and questionnaires to assess the adherence rate. It will be measured by the percentage of patients who attend the first two coaching sessions (either in person or via videoconference) relative to the total number of patients included in the study. The invitation to participate in this program will be made by the surgeon, hematologist, oncologist, or radiation therapist.

This multicenter phase II study evaluates a de-escalation strategy of neoadjuvant chemo-immunotherapy in patients with stage II early triple-negative breast cancer and tumor-infiltrating lymphocytes (TILs) ≥ 30%. Patients will receive 12 weeks of neoadjuvant treatment with carboplatin, paclitaxel, and pembrolizumab. The primary objective is to assess the efficacy of this treatment strategy by evaluating the proportion of patients with no suspected residual tumor on breast MRI and biopsy after 12 weeks of neoadjuvant therapy, confirmed by pathological examination of the surgerey sample.

The goal of this interventional study is to learn about the efficacy of first-line chemotherapy with Gemcitabine in metastatic pancreatic adenocarcinoma patients expressing the GemCore signature in their tumor. The main question it aims to answer is to assess efficacy of Gemcitabine (tumor response, survival rate) in the population of patient bearing the GemCore signature. Participants will start the chemotherapy with Gemcitabine as usually performed in standard care of their center. They will consent to a genomic analyze of their tumor to know if it bears the GemCore signature. The center will manage the participant's follow up as usually realized in standard care.

quantification of BTNL molecules in colon cancer in order to determinate if their could be used as a prognostic marquer

The goal of this observational study is to develop and validate a preoperative immunological signature for predicting postoperative pancreatic fistula (POPF) in adult patients undergoing pancreatic surgery for pancreatic cancer. The main questions it aims to answer are: * Can a preoperative immunological signature accurately predict the occurrence of postoperative pancreatic fistula after pancreatic surgery? * Does the immunological signature provide better predictive performance than currently available predictors? Researchers will also evaluate whether the immunological signature is associated with postoperative readmission, 90-day mortality, and early disease recurrence within one year after surgery. Participants will: * Provide a blood sample during the preoperative assessment visit. * Provide a second blood sample on the day following pancreatic surgery. * Undergo standard postoperative and oncological follow-up for up to 12 months. This is a prospective, multi-center, open-label observational study conducted at Institut Paoli-Calmettes. A total of 310 participants will be enrolled.

The present project aims to elucidate the metabolic interactions within the tumor microenvironment of pancreatic adenocarcinoma, both in the primary tumor and in hepatic and pulmonary metastatic sites, as well as in circulating blood biomarkers. Deciphering these complex interactions aims to identify exploitable vulnerabilities for predicting treatment efficacy or for guiding therapeutic strategies.

Immunotherapy has helped improve the prognosis of metastatic lung cancer. However, only about 40% of patients respond to conventional immunotherapy with anti-PD(L)-1 agents. This research aims to identify biomarkers of response to immunotherapy at the tumor level and to characterize new therapeutic targets

Acute myeloid leukemia (AML) and high-risk myelodysplastic syndromes (MDS) predominantly affect older adults, and their incidence continues to rise with advanced age. For many patients, allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only curative option capable of providing long-term disease control through the graft-versus-leukemia (GVL) effect. Historically, however, allo-HSCT was rarely offered to patients older than 50 years because of the high morbidity and mortality associated with myeloablative conditioning regimens and limited supportive care strategies. Over the past two decades, advances in reduced-intensity conditioning (RIC), infection prophylaxis, and donor availability have profoundly transformed the landscape, allowing increasing numbers of older patients to access transplantation. Multiple studies have demonstrated that allo-HSCT confers a survival benefit in older AML patients in complete remission compared with consolidation chemotherapy alone. The intensity of conditioning profoundly influences both relapse risk and non-relapse mortality (NRM). myeloablative conditioning (NMAC) regimens are attractive for older adults due to their low toxicity but rely solely on the immunologic GVL effect and thus carry a higher relapse risk. Reduced-intensity conditioning (RIC) regimens, incorporating intermediate-dose alkylating agents such as busulfan, melphalan, or thiotepa, offer stronger anti-leukemic effect but at the cost of greater toxicity. These observations underscore the central question: can a conditioning regimen combine strong anti-leukemic potency with the low toxicity required for older patients undergoing Haplo-SCT? The main objective is to evaluate the efficacy of FT-RIC regimen before Haplo-SCT for older and/or frail patients diagnosed with AML, who are not eligible for a myeloablative conditioning (MAC) regimen. To achieve this objective, the investigators will assess Progression Free Survival (PFS) defined as the time from allo-HSCT to AML relapse or death. This is a Multicenter trial, single arm prospective of phase II. Once the conditioning has been administered and the transplant performed, the patient will receive standard routine follow-up care, with the addition of questionnaires, and for patients followed at the Institut Paoli Calmettes only, blood samples will be collected.

Pancreatic cancer exhibits significant heterogeneity, which poses a major challenge in selecting the best treatment for patients from the very beginning of care. Modern oncology recognizes the use of companion biomarkers to guide targeted therapy or immune checkpoint inhibitors. However, with regard to chemotherapy-which has long been the cornerstone of cancer treatment and remains crucial for most cancers-few predictive tests are available to guide the choice between monotherapy and combination chemotherapy. Patients included in the PRODIGE 104 B - NEOPREDICT study will be those for whom the GEM transcriptomic signature is negative. This population will be treated according to the standard strategy and will be followed clinically and biologically to describe and identify the characteristics specific to this subgroup, and to compare the usual prognostic factors of this population with those of the GEM-positive population included in the parallel PRODIGE 104 A - NEOPREDICT study

In the current era of immune checkpoint inhibitors (ICI), the role and timing of nephrectomy remains unknown, particularly in cases of residual kidney disease after a major response at metastatic sites. In these cases, the rationale for a delayed nephrectomy is that it might achieve a long-term response. This strategy could allow some patients to discontinue treatment and maintain tumor response. Furthermore, this approach might provide a potentially curative option for patients with metastases that are managed with and responding to ICI. Regarding the results of our first retrospective cohort data (showing that two thirds of patients are free from recurrence without systemic treatment after nephrectomy), we designed a non-comparative randomized phase II trial assessing progression-free survival of patients with complete response or major partial response after ICI-based treatment, operated on delayed nephrectomy with discontinuation of systemic therapy (experimental arm) and in patients managed with continuation of systemic therapy without nephrectomy (control arm). In a de-escalation approach, this strategy may have sense to allow patients with an excellent response to immunotherapy to stop systemic treatment with a curative objective and a substantial impact from a medico-economic point of view.

The goal of this clinical trial is to test efficacy and safety of a VENETOCLAX-AZACITIDINE (VEN-AZA) de-escalation strategy in Acute Myeloid Leukemia responding patients. The main objectives of the study are: * Evaluation of the efficacy of VEN-AZA de-escalation strategy by measuring the effect of VEN-AZA discontinuation in term of Disease-Free Survival. * Evaluation of the other efficacy parameters and safety of VEN-AZA de-escalation strategy. Patients from the prospective study will be compared to a retrospective cohort of patients who will be selected on the basis of identical eligibility criteria. Participants will: * Stop VEN-DASA treatment * Be closely monitored by regular evaluation of the disease

Cervical cancer is the fourth most common cancer among women and is mainly linked to infection with high-risk human papillomaviruses (HPV). Although most HPV infections resolve spontaneously, 570,000 women were diagnosed with cervical cancer in 2018, and more than half of them died from the disease. For locally advanced disease, concurrent chemoradiotherapy (RT-CT) followed by brachytherapy is considered the standard therapeutic treatment. Even though progress has been made in chemotherapy, external beam radiotherapy, and brachytherapy over the past decades-on the one hand by reducing the duration of chemotherapy-induced cytotoxicity, and on the other hand by decreasing radiation doses delivered to organs at risk-hematologic toxicity following concurrent chemoradiotherapy remains a frequent complication. The indication and benefit of chemotherapy have been demonstrated in phase III clinical trials; however, grade 3 hematologic toxicity (anemia, leukopenia, and thrombocytopenia) remains between 18.7% and 21.3%. Since total treatment duration is a prognostic factor for local control, brachytherapy must be administered near the end of or immediately after RT-CT so that total treatment time is as short as possible (≤ 50 days). If grade 3 hematologic toxicity persists after RT-CT (prior to brachytherapy), brachytherapy will be delayed, leading to a loss of disease control (Tanderup et al., 2016). Dose reduction to the bone marrow is possible, but to date no randomized trial has evaluated it. The objective of this multicenter French study is to assess whether bone-sparing-contouring of the pelvic and/or lumbosacral osseous structures as an organ at risk (OAR) during external radiotherapy planning-reduces the incidence of grade ≥ 3 hematologic toxicity and the use of leukocyte growth factors, platelet transfusions, and/or blood transfusions, while adhering to current recommendations and without compromising clinical outcomes in patients treated with RT-CT and brachytherapy for locally advanced cervical cancer.

The present project aims at identifying robust candidates for drug resistance in BC patients eligible for NAC. Its originality lies upon the combination of three different and complementary prospective approaches: from the molecular analyses of biopsies sampled before and after NAC, from in vitro BC Patient-Derived Organoids (PDO) mimicking patient's response to NAC, and from Circulating Tumor Cells (CTCs) isolated before/during/after NAC.

Pancreatic radiofrequency ablation (RFA) could therefore be an alternative to the monitoring of pancreatic neuroendocrine tumors (PNETs) and more particularly nonfunctioning PNETs (NF-PNETs), which is costly and anxiety-inducing for patients. To date, only a few small studies have evaluated this treatment and the results are encouraging. It appears necessary to consider a large-scale study to ensure the efficacy and low morbidity of pancreatic RFA applied to PNETs.

The main objective of this study is to evaluate the pre-filling work on target and non-target lesions, and the detection of any new lesions reported by the MEM trained in protocol evaluations, in a structured table to prepare the radiologist's work in interpreting RECIST 1.1 scans. To meet this objective, patients taking part in the CIMER study will first have been included in a research protocol requiring scans with RECIST 1.1 interpretation. The Baseline examination will be performed and interpreted according to RECIST 1.1 without informing the radiologist performing the reading that the patient is included in the study, so as not to introduce an interpretation bias. During the first evaluation. The investigating MEM alone will carry out a preliminary analysis of the first evaluation and will present his results to the radiologist in charge of the evaluation, who will validate the conformity of the results.

The use of an endoprothesis in a pancreatic duct is a measure to minimize the incidence and severity of Post-Endoscopic Retrograde CholoangioPancreatography Pancreatitis. In this study we will evaluate the use of a Biodegradable Endoprothesis: Archimede Fast Biodegradable Pancreatic Stent in patients with high risk of Post-Endoscopic Retrograde CholoangioPancreatography Pancreatitis.The ARCHIMEDES Fast biodegradable pancreatic stent will be placed during the Endoscopic Retrograde CholoangioPancreatography. The efficacy and the security of the device will be evaluated.

Our goal is to create novel CD47-SIRPα inhibitors using small molecules to reverse TAM-mediated immune suppression and restore anti-tumor immunity in CRCs. Our program uses structure-based drug design to create selective and potent small molecule inhibitors of SIRPα-CD47 to target the tumor microenvironment with greater efficacy and lower toxicity than CD47-targeting antibodies. . In order to study the activity of CD47-SIRPα inhibitors on the immune microenvironment of tumors, we propose to use organoids derived from biopsies of patients with colon cancer. Tumoroids preserve the patient's tumor stroma (including myeloid cells) and provide an accurate in vitro model of complex tumor immune interaction for the evaluation of immunotherapies.

CDK4/6 inhibitor in combination with endocrine treatment is the standard of care in advanced breast cancer (ABC) with expression of hormone receptors and without HER2 overexpression (ER+/HER2-). When patients experience disease progression under this strategy, options of second-line endocrine treatment in combination with other targeted therapies are limited and have failed to improve overall survival to date over endocrine treatment alone. A significant fraction of ER+/HER2- ABC display genetic alterations associated with homologous recombination deficiency (HRD) which may be associated with efficacy of therapeutic targeting DNA damage response (DDR) pathways. Moreover, other molecular alterations associated with replicative stress may be found in ER+/HER2- ABC patients which may also favor antitumor activity of DDR targeting therapeutics. M1774 is a novel orally administered inhibitor of ataxia telangiectasia and rad3-related (ATR), a protein kinase with key activity in DDR pathway. MATRIx is a phase I/II study aiming to determine the recommended phase II dose (RP2D, phase I) as well as efficacy and safety (phase II) of M1774 in combination with fulvestrant in ER+/HER2-ABC patients whose disease has become resistant to aromatase inhibitor plus CDK4/6 inhibitor, and whose tumor displays molecular alterations associated with HRD, oncogenic driver activation and/or replicative stress. Primary endpoints will include: maximum tolerated dose (MTD) of M1774 in combination with fulvestrant (phase I), the clinical benefit rate and toxicity of the combination at RP2D of M1774 in the molecularly selected population (phase II). Baseline, on-treatment and post-treatment blood and tumor tissue samples will be collected for pharmacokinetics and translational analyses including genomic characterization of tumor tissue and ctDNA as well as functional studies focusing on DDR pathways.

This trial is a prospective, exploratory and descriptive study. The primary objective is to identify early diagnostic biomarkers in patients with TIPMP based on the analysis of Treg lymphocyte subpopulations and epigenetic signatures, and the secondary objective is to characterize the biological processes underlying the transformation of a pre-neoplastic lesion into established ADPC.

A cerebrospinal fluid sample will also be collected if a Cerebrospinal Fluid Analysis Lumbar puncture is performed

feasibility of using a diffusion sequence of a MRgRT system as an early marker of treatment response during nRCT of rectal adenocarcinoma.

NACT is a heavy oncologic treatment, which can impair functional capacity, nutritional and emotional status. These three impairments are often ignored and not taken into account in the pre-therapeutic evaluations but are correlated with postoperative morbidity and mortality after major surgery. Recently, a prehabilitation before surgery, including physical, nutritional and psycho-social support, has been defined. From a literature review, the maximum oxygen uptake (VO2 max) seems to constitute a strong evaluation factor reflecting physical fitness, easily measured with a cardiopulmonary exercise test (CPET) at maximal effort. Several studies have shown beneficial effects of trimodal prehabilitation programs on postoperative functional capacity, return to daily activities and pain relief. Home-based program and connected devices may improve the feasibility and the compliance to this program. The hypothesis of this study is that performing a connected supervised home-based and patient-tailored multimodal prehabilitation program from diagnosis to surgery (with or without ERAS program) during NACRT, for patients managed for ovarian cancer, will limit physical fitness alteration and will positively affect postoperative outcomes. Our study consists in an early and multidimensional (combining nutritional, physical, emotional and medical support) prehabilitation program during NACT for patients with ovarian cancer, in order to limit physical alteration before surgical treatment, and therefore improve postoperative outcomes. It will include a home-based prehabilitation program, in order to allow care access to all eligible patients.
