Active clinical trials for "Carcinoma"

Solid tumours often have highly disorganised vasculature that results in low oxygenation. This combined with high metabolic rates leads to oxygen demand outstripping supply causing tumour hypoxia. Hypoxia drives multiple cellular processes involved in the hallmarks of cancer. Tumour hypoxia also decreases the effectiveness of anticancer treatments. This is especially true for patients treated with radiotherapy since it has been long recognised that hypoxic tumour cells require 3 times the dose of radiation to cause the same amount of cell death as cells irradiated under normal oxygen conditions. To date, the majority of attempts at overcoming tumour hypoxia have focused on increasing oxygen supply. However, such techniques have produced modest benefits at best and subsequently have not been adopted into current clinical practice. An interesting alternative approach to tackling tumour hypoxia is to decrease oxygen 'demand' by reducing tumour oxygen consumption. This strategy has been suggested to be more effective in reducing hypoxia than previous methods aimed at increasing oxygen delivery. Pre-clinical data demonstrates that the commonly prescribed anti-protozoal drug atovaquone significantly reduces oxygen consumption in a variety of tumour cell lines in vitro. This reduction in oxygen consumption leads to a profound reduction in tumour hypoxia in animal models. It is anticipated that if these effects on tumour hypoxia could be reproduced in humans, that their tumours could be rendered markedly more sensitive to radiotherapy. This window of opportunity trial will assess whether atovaquone significantly reduces tumour hypoxia in adult patients referred for surgery with suspected non-small cell lung cancer. This will be assessed using a combination of functional imaging and circulating markers of hypoxia. If atovaquone is demonstrated to result in a reduction in tumour hypoxia, larger clinical trials will be conducted to determine whether this well-tolerated and inexpensive agent improves radiotherapy efficacy and clinical outcomes.

The goal of this study is to start treatment with the NOTCH1 inhibitor brontictuzumab in an attempt to control tumors and prolong survival. The therapy involves participant being given the drug brontictuzumab to treat adenoid cystic carcinoma (ACC) with NOTCH 1 mutations. This is considered an investigational treatment.

The purpose of this study is to characterize the safety and tolerability and determine the maximum tolerated dose (MTD) or the recommended fixed dose of the combinations of mogamulizumab and nivolumab in subjects with locally advanced or metastatic solid tumors.

The general aim of the study is to evaluate the anti-tumour activity and the tolerance profile of Pembrolizumab + RT in comparison to cetuximab + RT in patients with locally advanced HNSCC and to explore potential correlations between treatment outcome and the immune landscape.

This is a study of pembrolizumab (MK-3475) in participants with previously systemically treated advanced hepatocellular carcinoma (HCC). The primary objectives of this study are to determine 1) Progression-Free Survival (PFS) and 2) Overall Survival (OS) of pembrolizumab plus best supportive care (BSC) compared with placebo plus BSC. The primary hypotheses of this study are: 1) pembrolizumab plus BSC prolongs PFS per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, assessed by Blinded Independent Central Review compared to placebo plus BSC, and 2) pembrolizumab plus BSC improves OS compared with placebo plus BSC. Effective with Amendment 4: Upon study completion, participants are discontinued and may be enrolled in a pembrolizumab extension study, if available.

This study will evaluate the safety of adding nivolumab to several chemotherapy platforms with weekly cisplatin, high-dose cisplatin, cetuximab or radiation therapy alone.

This is a non-randomized, phase II, open label study of postoperative concurrent chemoradiotherapy with docetaxel for high-risk squamous cell carcinoma of the head and neck(HNSCC).The primary purpose of this study is to evaluate the efficacy and safety of concurrent chemoradiotherapy with docetaxel in HNSCC patients.

This is an open-label, single site, Phase IIA clinical trial to investigate the safety and efficacy of an individualized anti-cancer vaccine (CRCL-AlloVax) in advanced HCC patients.

In this study, participants with previously-treated locally-advanced unresectable or metastatic mismatched repair (MMR) deficient or microsatellite instability-high (MSI-H) colorectal carcinoma (CRC) will be treated with pembrolizumab (MK-3475, KEYTRUDA®) monotherapy. There will be two cohorts in this study: Cohort A and Cohort B. For Cohort A, participants are required to have been previously treated with standard therapies, which must include fluoropyrimidine, oxaliplatin, and irinotecan. Enrollment into Cohort A has been completed. For Cohort B, participants are required to have been previously treated with at least one line of systemic standard of care therapy: fluoropyrimidine + oxaliplatin or fluoropyrimidine + irinotecan +/ - anti-vascular endothelial growth factor (VEGF)/ epidermal growth factor regulator (EGFR) monoclonal antibody. The primary hypothesis is that Objective Response Rate (ORR) based on Response Evaluation Criteria in Solid Tumors v 1.1 (RECIST 1.1) assessed by central imaging vendor in participants with locally advanced unresectable or metastatic MMR deficient or MSI high CRC is greater than 15%.

The purpose of this study is to evaluate the safety and efficacy of ramucirumab in participants with hepatocellular carcinoma (HCC) and elevated baseline alpha-fetoprotein. Participants will be randomized to ramucirumab or placebo in a 2:1 ratio (Main Global Cohort and China Maximized Extended Enrollment [MEE] Cohort). Participants may also receive ramucirumab if eligible to be enrolled in Open-Label Expansion (OLE) Cohort.
