NCT07499128
Background: Drugs or cell therapies to treat cancer can sometimes cause cytokine release syndrome (CRS). That is, the body makes too many cytokines after treatment. Cytokines are proteins that play a role in the immune system. CRS can cause fever, chills, fatigue, low blood pressure, or breathing problems. Researchers want to know if continuously monitoring a person s body temperature can help reduce the chance of getting serious CRS. Objective: To learn if an approved patch called TempTraq can detect fever before serious CRS develops. Eligibility: People aged 18 years and older with cancer who are staying at the NIH clinic for treatment with drugs or cell therapies. Design: Participants will receive TempTraq patches and a special NIH tablet. The TempTraq is a small patch applied to clean, dry skin under the arm. It continually monitors body temperature and sends the data to an application on the tablet. Participants will wear the patch most of the time they are admitted to the hospital. They could wear it for up to 15 days. The patch monitoring does not replace regular temperature checks, all participants will still have have their regular temperature checks as part of their treatment plan. Participants may also opt to use VitalTraq, another application on the tablet. They will hold the screen up to their face for about 1 minute. VitalTraq uses the camera in the tablet to measure blood pressure, heart rate, and breathing. They will do this once per day while they are in the clinic; they may do it more often if they have a fever or feel unwell. Blood may be drawn for research. Participants will be asked about their experience within 1 week after TempTraq is removed. Participants who choose to use the patch, complete its use, and return at a later date for another treatment or study, may be able to re-enroll to have the patch used again.

The study is a randomized, double blind, placebo-controlled, non-comparative phase II trial that investigates the efficacy of neoadjuvant anti-PD-1 antibody Cemiplimab treatment in patients with clinical stage I or II Merkel cell carcinoma who have have undergone primary tumour excision and are pending sentinel lymph node biopsy.
NCT07528066
The goal of this observational study is to learn whether tumor and nodal downstaging after neoadjuvant chemo-immunotherapy is associated with better surgical outcomes in patients with clinical stage IIB-III non-small cell lung cancer (NSCLC) undergoing robotic-assisted thoracic surgery. The main question it aims to answer is: Is downstaging after neoadjuvant chemo-immunotherapy associated with better surgical outcomes in patients with stage IIB-III NSCLC undergoing robotic-assisted surgery? Participants with resectable or potentially resectable stage IIB-III NSCLC who receive neoadjuvant chemo-immunotherapy as part of their routine clinical care and then undergo curative-intent robotic-assisted surgery will be prospectively enrolled from international centers. Clinical, operative, pathological, and postoperative outcome data will be collected, including R0 resection, the extent of resection, conversion to open surgery, postoperative complications, length of stay, readmission, and mortality.

NCT07478900
Study Description This prospective cohort study evaluates the feasibility and effectiveness of pre-neoadjuvant tumor localization using skin tattooing, with or without radiopaque clips, in patients with biopsy-proven T2-T3 breast cancer and axillary lymph node metastasis. Eligible patients will undergo tumor localization in the supine position with the ipsilateral arm abducted to 90°. Palpable tumor margins will be marked with sterile tattoo ink, and deep or mobile tumors will receive additional localization with ultrasonography-guided radiopaque clips. Following localization, patients will receive standard neoadjuvant chemotherapy. Tumor response will be monitored clinically and radiologically. Post-therapy, the tattoo markings and/or clips will guide breast-conserving surgery. Primary outcomes include feasibility of breast conservation, achievement of negative margins (R0 resection), and avoidance of mastectomy, while intraoperative technical challenges will also be documented.
NCT04225390
PROMIT is a single arm phase 2 trial evaluating the clinical activity of immune checkpoint blockade (ICB) after administration of dacarbazine (DTIC) in patients with unresectable or metastatic, BRAF wildtype melanoma with primary resistance to anti-programmed-cell-death-1 (PD-1/PD-L1) or PD-1 plus anti-cytotoxic-T-lymphocyte antigen 4 (CTLA-4) blockade therapy. If the activity is clinically meaningful, DTIC could become a new therapeutic option to break primary resistance to immunotherapy.

NCT07373899
This study intends to conduct a prospective, non-interventional study to compare the survival benefits of different surgical resection patterns for patients with non-small cell lung cancer who have achieved partial response (PR) after immunotherapy induction. The study plans to enroll patients suitable for surgery as assessed by radiomics evaluation and multidisciplinary team (MDT) discussion, and will assign them to the modified surgery group and the conventional surgery group based on patient preference. The resection scope in the modified surgery group is more limited compared to conventional surgery, aiming to maximize preservation of pulmonary function while ensuring oncological safety. This study will systematically evaluate the impact of different resection scopes on patient prognosis after neoadjuvant immunotherapy, providing clinical evidence for exploring individualized surgical strategies for non-small cell lung cancer in the era of immunotherapy.
NCT07324473
Background： Hepatocellular carcinoma (HCC) stands as a formidable global health challenge. It ranks as the sixth most common malignant solid tumor worldwide and the third leading cause of cancer-related mortality. The disease is characterized by its insidious onset, rapid progression, and high recurrence rates, contributing to a dismal 5-year survival rate of approximately 18%. A critical factor in this poor prognosis is that nearly 57% of patients are diagnosed at an advanced stage, where curative surgical resection is no longer feasible. For these patients with unresectable advanced HCC (uHCC), effective systemic therapies are paramount to extend survival and improve quality of life. The advent of immunotherapy, particularly immune checkpoint inhibitors (ICIs) targeting the PD-1/PD-L1 axis, has revolutionized the treatment landscape for numerous advanced cancers, including uHCC. These agents work by blocking the inhibitory signals that tumor cells exploit to evade immune surveillance, thereby reactivating cytotoxic T cells to attack the cancer. However, the clinical benefit of ICI-based therapies is not universal. A substantial proportion of patients-estimated between 15% to 40%-derive limited or no benefit. Primary resistance is defined as a lack of initial response, while acquired resistance refers to disease progression after an initial period of clinical benefit. There is no established, evidence-based standard of therapy for uHCC patients who progress following first-line ICI combination therapy, highlighting an urgent need for novel therapeutic approaches. The mechanisms underlying acquired resistance to ICIs are multifaceted and intricately linked to dynamic remodeling of the tumor immune microenvironment (TME). Several key pathways contribute: 1. Loss of Tumor Immunogenicity: Immune editing during treatment can select for tumor cell clones with low neoantigen expression, making them less visible to the immune system. 2. Immune Suppressive Cell Infiltration: The TME in resistant tumors often exhibits an accumulation of immunosuppressive cell populations, including regulatory T cells (Tregs), tumor-associated macrophages (TAMs), and myeloid-derived suppressor cells (MDSCs). These cells create a profoundly inhibitory milieu that dampens anti-tumor T cell function. 3. T Cell Exhaustion: Persistent antigen exposure leads to a state of CD8⁺ T cell exhaustion, rendering them dysfunctional. These interconnected mechanisms collectively foster an immunosuppressive TME that allows tumors to evade ongoing immune attack, underscoring the need for combination strategies that can reshape the TME and re-sensitize tumors to immunotherapy. The JAK-STAT pathway serves as a critical signaling hub for numerous cytokines and growth factors, playing a pivotal dual role in immunity and inflammation. In the context of HCC and ICI resistance, its activation is particularly relevant: 1. Pathway Activation in HCC: The JAK/STAT pathway is ubiquitously activated in both primary and recurrent HCC tumors and contributes to the proliferation and survival of tumor-initiating cells. 2. Driver of an Immunosuppressive TME: Hyperactivation of this pathway, often via cytokines like IL-6, promotes the recruitment and activation of immunosuppressive MDSCs and M2-polarized TAMs. It also contributes to T cell exhaustion. 3. Preclinical and Clinical Proof-of-Concept: In preclinical models, JAK/STAT inhibition has been shown to reduce MDSC infiltration and restore T cell function. Most compellingly, recent clinical studies in other cancer types published in high-impact journals like Science (2024) have demonstrated that adding a JAK inhibitor to PD-1 blockade can re-sensitize tumors and yield significant clinical responses in patients who had developed resistance to immunotherapy alone Purpose: This single-arm, exploratory clinical study aims to evaluate the efficacy and safety of Ivarmacitinib (a selective JAK1 inhibitor) combined with Camrelizumab (anti-PD-1) and Apatinib (anti-VEGFR2) in patients with advanced unresectable HCC who have progressed after first-line ICI-based combination therapy. Methods: This study plans to enroll 65 patients with advanced unresectable hepatocellular carcinoma (unresectable BCLC stage B or stage C) who have been clinically or pathologically diagnosed, have previously received at least 4 cycles of guideline-recommended first-line targeted therapy combined with PD-1/PD-L1 immunotherapy, achieved a partial response, but subsequently experienced disease progression confirmed by RECIST 1.1 criteria after at least 4 cycles (indicating acquired resistance). All enrolled patients will receive triple therapy consisting of Ivarmacitinib + Apatinib + Camrelizumab. Treatment will continue until disease progression, unacceptable toxicity, or for up to 2 years.

NCT07300891
This is a Phase 2, single-arm, multicenter study, evaluating the anti-tumor efficacy of tumor-infiltrating lymphocyte (TIL) directed tislelizumab monotherapy (also known as BGB-A317) for refractory solid tumors in approximately 72 patients with centrally confirmed T cell inflamed GEP score ≥ 0.857, who have not been previously exposed to immunotherapy. All patients must provide a tumor specimen for T cell inflamed GEP assessment. Archived tissue slide collected within 2 years from the first dose of study drug must be provided. This study will include a Screening Period, a Treatment Period, and a Follow-Up Period. All patients will complete up to 28 days of screening. During the Treatment Period, patients will receive tislelizumab 200 mg fixed dose once every 3 weeks by intravenous (IV) administration until disease progression, unacceptable toxicity, withdrawal of consent, or study termination. After treatment discontinuation, patients will be follow-up for disease progression and survival status until death, withdrawal of consent, or study closure, whichever occurs first. The end of study will be the timepoint when the final data for the study were collected. Additionally, the Investigator Sponsor has the right to terminate this study at any time.

NCT07273708
The study aims to analyze blood samples from patients with advanced hepatocellular carcinoma who are receiving systemic treatment with immunotherapy. The objective is to determine whether treatment exposure leads to changes in the transcriptomic patterns of peripheral blood mononuclear cells (PBMCs), if these changes are associated with treatment response, and whether certain pre-treatment transcriptomic signatures can predict response to treatment. As an exploratory objective, PBMCs derived from patients exposed to immune checkpoint inhibitors will be co-cultured with their paired tumor cells in organoid cultures. This aims to assess whether these preclinical 3D models correlate with clinical outcomes.
NCT07269158
"Biliary tract cancer (BTC) is a rare malignancy with a poor prognosis. Most patients present with unresectable disease, and even after curative-intent resection, recurrence is common. Since the ABC-02 trial, gemcitabine plus cisplatin (Gem/Cis) has been established as the standard first-line regimen, but the median overall survival (OS) remains approximately 11.7 months. Recent studies combining immune checkpoint inhibitors (ICIs) such as durvalumab or pembrolizumab with Gem/Cis have improved OS to 12.7-12.9 months, establishing ICI-based combination therapy as the new standard. However, the optimal maintenance therapy following initial chemoimmunotherapy remains undefined. This phase IIb study enrolls patients with advanced BTC who achieved disease control after at least eight cycles of Gem/Cis plus ICI. The trial compares the efficacy and safety of ICI monotherapy maintenance versus ICI in combination with lenvatinib, venadaparib, or interleukin-2 (IL-2, SLC-3010). Lenvatinib, through inhibition of FGFR2 and modulation of the tumor immune microenvironment, is expected to enhance ICI efficacy. PARP inhibitors may be beneficial in patients with homologous recombination deficiency (HRD) or platinum-sensitive disease. Additionally, IL-2 can activate tumor-infiltrating lymphocytes and alleviate the immunosuppressive microenvironment, potentially augmenting ICI responsiveness. This study aims to explore a novel maintenance strategy integrating molecular targeted therapy, DNA damage repair modulation, and cytokine-based immunotherapy to overcome the limitations of current ICI monotherapy in BTC. The combination approach is expected to improve disease control and survival outcomes in patients with advanced BTC.
