Filter by:Over the past few years it has become evident that cancer cells can be recognized by the patient's own immune system. The immunological mechanisms at play are often referred to as the "cancer immune cycle" (Chen and Mellman 2013; Mellman 2013; Chen and Mellman 2017).In immune-evasive tumors a pivotal role has been attributed to myeloid dendritic cells (myDC) in regulating the activity of anti-tumor CTL activity within the TME (Broz, Binnewies et al. 2014). In animal models, myDC have been demonstrated to play an essential role in "licensing" anti-tumor CTLs to eradicate tumor cells. These myDC also migrate to tumor-draining lymph nodes and present tumor antigens to T-cells in these secondary lymphoid organs (Roberts, Broz et al. 2016). Human myDCs exist in two subsets that are differentiated by expression of either the BDCA-1 or BDCA-3 surface marker. The CD1c (BDCA-1)+ antigen is specifically expressed on human dendritic cells, which are CD11chighCD123low and represent the major subset of myDCs in human blood (about 0.6 % of all peripheral blood mononuclear cells (PBMCs)). CD1c (BDCA-1)+ myDC play an important role in the cross-presentation of tumor antigens following immunogenic cell death (Di Blasio, Wortel et al. 2016). Under conditions of tumor growth, myDC will be poorly recruited to the tumor microenvironment, do not get activated and thereby fail to efficiently coordinate anti-tumor immunity within the tumor micro-environment and present tumor associated antigens within tumor-draining lymph nodes. Talimogene laherparepvec (T-VEC) is a first-in-class oncolytic virus based on a modified herpes simplex virus (HSV) type 1 designed to selectively replicate in and lyse tumor cells while promoting regional and systemic antitumor immunity. In this phase I clinical trial we propose to investigate the safety of intratumoral injection of autologous CD1c (BDCA-1)+ myDC in non-visceral metastases of melanoma plus intratumoral injection of T-VEC (at its approved dose and regimen for the treatment of melanoma). We hypothesize that CD1c (BDCA-1)+ myDC in the T-VEC inflamed tumor microenvironment of the metastasis will capture tumor antigens in vivo and through cross-presentation of these antigens coordinate an effective anti-tumor T-cell response.
A prevention study to improve sun exposure behaviors in children after an educational classroom-based intervention.
The main goal of this study is to evaluate the antitumor activity of relatlimab and nivolumab in combination in subjects with unresectable or metastatic melanoma who have not received prior treatment with immunotherapy.
This is an open label, single-arm, phase IB treatment study to determine the safety of administering anti-PD1 monoclonal antibodies with AV-MEL-1 and to get some suggestion of efficacy, in patients with measurable metastatic melanoma. The study is open to patients who have either never received treatment for metastatic melanoma or were previously treated with anti-PD-1 with or without anti-CTLA-4 or with enzymatic inhibitors of the BRAF/MEK pathway because of BRAF600E/K mutations, and are about to initiate anti-PD-1 monotherapy. The intent is to treat 14 to 20 patients with the combination of anti-PD-1 and AV-MEL-1.
Study the EFS and OS according to 18FDG PET in patients with melanoma or non small cell lung cancer treated by immunotherapy.
Studies have shown that tumors from the same patient may respond very differently to the same therapeutic agents. This study aims to investigate the genetic basis of tumors that respond abnormally well or poorly to therapeutic agents in an effort to understand the fundamental genetic basis of this response. The present protocol seeks to retrospectively perform Exome, next-generation (DNA) sequencing and/or other molecular techniques on tumor samples to identify the genetic basis of a patient's exceptional response to chemotherapy.
The goal of this study is to describe patient characteristics, treatment outcomes and adverse events for patients with metastatic melanoma testing positive for PD-L1 expression treated first line (1L) with either nivolumab and ipilimumab in combination (NIVO + IPI) or nivolumab (NIVO) monotherapy
The purpose of this study is to evaluate the safety and tolerability, pharmacokinetics (PK) pharmacodynamics and preliminary antitumor activity of vobramitamab duocarmazine (MGC018) in patients with advanced solid tumors. Patients with solid tumors will be enrolled in the Dose Escalation Phase; Cohort Expansion will include metastatic castrate-resistant prostate cancer (mCRPC), non-small cell lung cancer (NSCLC), triple-negative breast cancer (TNBC), squamous cell carcinoma of the head and neck (SCCHN), and melanoma. Patients who do not experience unacceptable toxicity or meet criteria for permanent discontinuation may undergo additional cycles for up to two years. Patients in Cohort Expansion will be followed for survival every 3 months for 2 years following last dose.
The purpose of this study is to collect blood and clinical data from patients with metastatic melanoma and renal cell cancer who have experienced spontaneous regression for studies of immune response and other factors that may influence these occurrences.
Up to 50% of patients with unresectable metastatic melanoma will develop brain metastases during their lifetime. A possible treatment options for patients with brain metastases are surgery and radiotherapy but usually for lesions in the range of < 3 brain metastases. This study was performed to evaluate the addition of immune checkpoint inhibitors in patients with stage IV melanoma with > 3 symptomatic brain metastases, who are not eligible for surgery or radiosurgery.
