Immune-related Adverse Event

The purpose of this study is to characterize the pharmacokinetics of one or more ICIs during and after TPE/PLEX in patients with severe irAEs.

The introduction of immune checkpoint inhibitors (immunotherapy) that stimulate our immune system to recognize and attack cancer cells has been one of the most exciting advances in oncology over the last decade. These medications are now employed across almost half of cancer types and settings, however they come with a cost. In some patients, instead of attacking cancer cells alone, the stimulated immune system damages healthy tissues (immune related adverse events), with one of the most severe and potentially deadly such complications being immune attack on the lungs, or checkpoint inhibitor pneumonitis (CIP). When treated promptly with oral or intravenous steroids, acute CIP improves in many cases, however for approximately one-fifth of patients the lung inflammation is difficult to control, resulting in recurrent shortness of breath, the need for extended courses of oral or intravenous steroids, impacting quality of life and cancer therapy decisions. The goal of the trial is to assess whether use of inhaled steroids, a type of medication commonly used in asthma patients, for one year after a first diagnosis of CIP may help the lung inflammation resolve and not return, without the repeated use of oral or intravenous medications that carry more side effects.

This phase II study evaluates whether early treatment with mycophenolate mofetil (MMF) plus prednisone improves liver inflammation caused by immune checkpoint inhibitors. The study includes patients who develop moderate to severe immune-related hepatitis after receiving PD-(L)1 or CTLA-4-based cancer therapy. The main goal is to determine how many patients experience improvement in liver function within 30 days while successfully tapering steroids. Safety and treatment-related side effects will also be monitored.

This study will examine the effectiveness of administering adalimumab as a treatment for patients in the early stages of steroid-dependent immune checkpoint Inhibitor associated inflammatory arthritis (ir-IA). Adalimumab (ADA) is a TNF inhibitor (TNFi) that is well established as a standard of care treatment for numerous types of inflammatory arthritis. It is hoped that adalimumab at the early stages of the ir-IA will reduce the symptoms and therefore reduce the need for steroids. This study is a pragmatic randomized clinical trial. Patients will be randomized 1:1 to each treatment group. To evaluate the steroid sparing effect of early induction six doses of Adalimumab will be administered to patients in the study treatment arm as compared to the usual standard of care of a predefined corticosteroid regimen and taper at 12 weeks administered in the control group.

The study team's principal interest is to address the question, "Will prophylactic treatment with mesalamine reduce the incidence and severity of immune-related diarrhea occurring secondarily to treatment with ipi/nivo?"

In the last decades, cancer treatment was based on surgery, radiotherapy and chemotherapy. Recently, treatments have largely evolved, first with targeted therapies (notably tyrosin kinase inhibitors, TKI) and then with immune checkpoint inhibitors (ICPI, notably anti-CTLA-4 and anti- PD1). The last ones can induce durable anti-tumoral responses in patients, even if metastases are present. Their mechanisms of action are focused on the activation of immune system in order to eliminate the tumor. ICPI, because of their mechanisms of action, target immune tolerance key components and can induce important immune toxicities (colitis, hepatitis, dermatitis, thyroiditis ...), leading to early discontinuation of treatment, severe or chronic morbidity, and can sometimes be lethal. It is of importance to detect patient at risk of irAEs, because of the increasing use of ICPI and the long- term response capacity in treated patients.

rDEN2Δ30-7169 is a dengue challenge strain that previously reports its viremia induction effect in participants with minimal symptoms in US flavivirus naïve participants. Moreover, preliminary result of five Thai dengue naïve participants from previous project (registered number NCT05476757) demonstrated 100% viremia status without severe adverse event after 60 days post-virus challenge. However, result from previous project may not fully represent the clinical manifestation and immunological responses of major population of endemic areas, where most people in endemic area have dengue immune status. Therefore, this controlled human infection model protocol proposes to challenge the attenuated virus in 12 dengue-immune participants recruited from Bangkok metropolitan area, Thailand. We aim to assess the safety, viremia, NS1 antigenemia profile, and immunogenicity of the challenge virus in the dengue immune participants. After finish safety assessment, all participants will be vaccinated with a full course of dengue vaccines to prevent recurrent dengue infection. Immunological responses after vaccination will be also evaluated the vaccine efficacy. Our expected outcomes are all participants present viremia profiles after virus challenge without serious adverse events (SAE). The exploratory profiles include assesment of immune profiles and parameters comparison with the other dengue challenge study.

The FORX (Food intervention to Reduce immunotherapy toXicity) trial will assess whether supplementing dietary fiber intake by providing weekly boxes containing 30 different plants to patients with solid tumors starting immune checkpoint inhibitor therapy affects the incidence of immune related adverse events.

The goal of this interventional study is to test whether atorvastatin prevents accelerated progression of atherosclerosis in melanoma patients who receive immune checkpoint inhibitor (ICI) therapy. The main questions it aims to answer are: * difference in percentage growth of total atherosclerotic plaque volume (+ calcified and non-calcified plaque volume) in the descending thoracic segment of the aorta * difference in percentage growth of total atherosclerotic plaque volume (+ calcified and non-calcified plaque volume) in coronary arteries. Researchers will compare patients that receive ICI-therapy and atorvastatin with patients that receive ICI-therapy + placebo to see if atorvastatin will prevent accelerated ICI induced plaque growth.

This study aims to explore the optimal number of cycles of PD-1 monotherapy required at minimum, under the premise of ensuring pathological complete response (pCR) among patients with dMMR/MSI-H rectal cancer. Participants will receive preoperative monotherapy with PD-1 antibodies, with regular reassessments every 2 cycles. Surgical intervention will be performed if clinical complete response (cCR) is achieved. Researchers will compare the pathological complete response rates, adverse reactions, and three-year event-free survival rates across different treatment cycles.

The main goal of this clinical trial is to evaluate dostarlimab, an immunotherapy drug, as a potential alternative to surgery for early-stage endometrial cancer with Mismatch Repair deficiency, a genetic cause for 20-30% of cases. The study aims to establish dostarlimab's efficacy and safety in early-stage endometrial cancer, exploring its potential as a non surgical option for those unsuitable or unwilling to undergo major surgery, allowing for fertility preservation or addressing specific health conditions. Participants will have seven dostarlimab sessions over 12 months. The treatment plan involves four cycles every three weeks, followed by a three-week break, and then three cycles every six weeks. This research is a promising step toward a new, less invasive treatment choice for patients with specific genetic traits. It expands the range of care options for endometrial cancer.

This is a prospective clinical study to clarify serum ferritin as a biomarker for the diagnosis, differential diagnosis and prognosis of immune-related adverse event(irAE).

Patients will either be treated with ECP or second line immunosuppressive therapy according to investigator's choice. Patients will be followed for 24 weeks after first treatment.
