Classical Hodgkin Lymphoma

This is a prospective randomized open-label, multicenter, 2-arm study to assess the role of healthy LifeStyle implemented Survivorship Care Plan (LS-SCP) in modifying the Quality of Life (QoL) in a population of long-term lymphoma survivors (in remission for a minimum 3 years since the last treatment and a maximum of 10 years).

Researchers are looking for new ways to treat children with different types of melanoma (skin cancer), solid tumors, and lymphomas (blood cancers) that are any of these: * Advanced, which means cancer spread in the body or cannot be removed with surgery * Relapsed, which means cancer has come back after it had responded to previous treatment (responded means it stopped growing, gets smaller, or disappeared) * Refractory, which means cancer did not respond to previous treatment Pembrolizumab is an immunotherapy, which is a treatment that helps the immune system fight cancer. Researchers want to learn if different doses of pembrolizumab can cause at least 1 of the types of cancer to get smaller or go away. With Amendment 8, enrollment of participants with solid tumors and participants 6 months to under 12 years old with melanoma were closed. With Amendment 13, enrollment was closed for participants with relapsed refractory classical Hodgkin lymphoma (rrCHL), microsatellite instabilty-high (MSI-H) solid tumors, tumor-mutational burden-high (TMB-H) solid tumors, and participants 12 years old to \<18 years old with advanced melanoma.

This is a phase 2 open-label study to test the safety and effectiveness of combining pembrolizumab and bendamustine in patients with relapsed (cancer that has come back or started getting worse) or refractory (cancer that is not responding or has stopped responding to treatment) Hodgkin lymphoma.

Classical Hodgkin's Lymphoma (cHL) is a rare but highly treatable malignancy of the immune system, primarily affecting young adults. Despite significant therapeutic advancements, frontline treatment failure occurs in up to 30% of cases, with relapse or refractory disease affecting over 50% of these patients. The main therapeutic challenge in cHL remains achieving an optimal balance between disease control and reducing long-term adverse effects. Current prognostic tools only partially capture patient heterogeneity, and cHL continues to evolve spatially and temporally throughout the course of the disease. Personalized treatment strategies require novel integrated tools that better monitor tumor complexity and anticipate disease progression. Fluorodeoxyglucose positron emission tomography (FDG-PET) has improved risk stratification in cHL, as metabolic response during or after chemotherapy strongly correlates with disease progression and survival. However, FDG-PET has limitations, including the absence of standardized criteria and the necessity to initiate treatment before response assessment. To overcome these limitations, molecular profiling and radiomic analysis of baseline FDG-PET data may provide deeper insights into tumor biology, improving prognostic accuracy. This observational study aims to dissect the genetic and phenotypic heterogeneity of cHL at diagnosis and during disease evolution, with the goal of identifying novel prognostic biomarkers. These findings could lead to better treatment personalization, increasing cure rates while minimizing treatment-related toxicity. The study is based on the hypothesis that correlating DNA profiling at diagnosis, gene expression, and radiomic features may enable the identification of high-risk signatures, refining prognostic models in cHL. Additionally, liquid biopsy represents a non-invasive method for assessing tumor mutational complexity. The analysis of circulating DNA (cDNA) throughout disease progression could provide insights into genetic evolution and help predict overt progression before clinical manifestations occur. The primary objective is to define the genetic mutational profile of cHL at disease progression. As secondary objectives, it will evaluate whether liquid biopsy can accurately recapitulate the genetic heterogeneity observed in tumor tissue, determine the predictive accuracy of liquid biopsy in anticipating disease progression, and correlate genomic and radiomic features with patient outcomes to refine risk stratification and therapeutic decision-making. By integrating molecular and imaging-based biomarkers, this study aims to enhance personalized treatment strategies, improve risk-adapted therapeutic approaches, and ultimately optimize curability and quality of life for patients with cHL.

Patients with relapsed low-risk CD30 classical Hodgkin Lymphoma will have autologous CD30 CAR T-cell manufactured. Dose escalation will be used to determine the RP2D. Following lymphodepletion, CAR T-cell will be infused.

Patients with poor risk classical Hodgkin Lymphoma (cHL) will undergo myeloablative chemotherapy (MAC) with autologous stem cell transplantation (AutoHSCT) and subsequently receive autologous CD30+ CAR T-cells.

Generally, pediatric patients tolerate acute toxicities but are vulnerable to late effects. Thus, increasing chemotherapy intensity to achieve more rapid complete early response to limit radiation therapy is worth testing. In this CCCG-HL-2024 study, Brentuximab vedotin (Bv) was used to replace VCR and bleomycin in the ABVE-PC regimen in the previous CCCG-HD-2018 study, respectively, to form a Bv-AEPC regimen for the treatment of newly diagnosed classic Hodgkin lymphoma (cHL) in children, adolescents and young adults. On the premise of maintaining a 4-year event free survival (EFS)\>90% in the low-, intermediate-and high-risk groups, increase the early assessment complete response rate (the overall early complete response rate increased by 20%, that is, from 54.0% to 74.0%) to further reduce the proportion of children receiving radiotherapy to benefit them.

Classical Hodgkin lymphoma (cHL) accounts for 15% of all cases of cancer in children and adolescents and represents the first cause of cancer during adolescence. Combined multi-modal chemotherapy and modern radiation techniques have transformed cHL in a highly curable cancer. However, up to 10-15% of patients still experience recurrent or primary refractory disease. Thus, there is an unmet need for unravelling the underlying mechanisms of treatment failure and refractoriness in paediatric cHL. Further refinements of treatment strategy are still needed to improve treatment results both in relapse and refractory (R/R) patients and to reduce long-term morbidity and mortality treatment related. Therefore, two main objectives arise: to improve early detection of patients with a high relapse risk to potentially intensify the first line treatment and to better identify low risk patients to further reduce the treatment burden in this good-prognostic population. Initial disease stratification and long-term outcome predictions remain a challenging issue in the field. PET/CT is currently the reference imaging method for initial staging and improves detection of extra nodal disease. None of previous prognostic factors accurately identify patients who will respond adequately and therefore limit the ability to identify patients who should require treatment that is more intensive or new therapeutic approaches like immunotherapy. Taken together, these data emphasize a clear unmet need in the field of cHL. We aim to develop a biomarker tool, which could sharpen the initial risk stratification, improve the assessment of disease evaluation during the treatment and beyond and facilitate the detection of relapse. Over the past decade, as in other malignancies the potential of quantification of circulating tumour DNA (ctDNA) or liquid biopsy, in circulating cell-free DNA (cfDNA) that comprises DNA fragments released from apoptotic or necrotic cells into circulation, has emerged as a promising tool for diagnosis and exploration of the genetic landscape associated with HRS and for response evaluation. Experiences of ctDNA in cHL was first reported in adult cHL. These previous studies paved the way for ctDNA implementation in cHL. First, they contributed to confirm the feasibility to use ctDNA in the detection of tumor-associated mutation. Using paired samples of ctDNA and tumor DNA from HRS cells obtained by microdissection they confirmed the consistent correlation between these two methods. Second, they highlighted the potential role of ctDNA as a surrogate marker for tumor baseline assessment and more importantly for interim evaluation reporting an excellent correlation between the PET/CT result and the presence or the absence of ctDNA after 2 cycles of chemotherapy. Furthermore, Sobesky et al. previously reported that cured patients who were inconsistently judged as interim PET/CT-positive had a more than 2-log drop in ctDNA, whereas relapsing patients who were inconsistently judged as interim PET/CT negative had a less than 2-log drop in ctDNA. These data suggest that ctDNA could be a relevant adjunct to conventional PET/CT approach.

By the implementation of the anti-PD-1 antibody pembrolizumab and given its possible synergy with RT, the aim of the present trial is to develop a chemotherapy-free first-line treatment for patients with newly diagnosed early-stage favorable cHL.

Study Purpose: To evaluate the efficacy and safety of sintilimab in combination with AVD chemotherapy for the treatment of pediatric and adolescent patients with low-to-intermediate risk classical Hodgkin lymphoma (cHL). Study Design: This is a prospective, single-arm, multicenter, phase II clinical trial. Study Population: Pediatric and adolescent patients aged 1 to 18 years, diagnosed with classical Hodgkin lymphoma, and classified as low-to-intermediate risk according to the Ann Arbor staging system. Treatment Plan: Sintilimab in combination with AVD chemotherapy, administered every two weeks for a planned 4-6 cycles.

The aim of this trial is to develop an effective and well-tolerated regimen for treatment of r/r cHL by introducing the anti-PD-1 antibody pembrolizumab and adding it to well-established chemotherapy regimens (ICE, DHAP). Synergistic effects of conventional agents with checkpoint inhibition may facilitate a highly effective therapy with limited toxicity, which might eventually substitute the very toxic high-dose chemotherapy (HDCT).

The aim of the trial is to establish an individualized first-line treatment incorporating checkpoint inhibition for early-stage unfavorable cHL, which is effective and well tolerated.

This is a multicenter, open-label single-arm phase II study to evaluate the efficacy and safety of Zimberelimab (GLS-010) combined with AVD for newly diagnosed early-stage Hodgkin's lymphoma under the guidance of PET/CT.
