NCT ID: NCT03374943 Recruiting - Glioblastoma Clinical Trials

A Trial of KB004 in Patients With Glioblastoma

Start date: December 5, 2017
Phase: Phase 1
Study type: Interventional

This is a study of drug KB004 in patients with recurrent glioblastoma (GBM). Eligible patients with measurable tumours will receive an initial trace (5mg) dose of zirconium labelled KB004 (89ZrKB004) on day 1 followed by sequential PET imaging over 1 week to determine its biodistribution into GBM and normal tissues. Safety assessments and pharmacokinetic (movement of drug) sampling will also be undertaken over this time. On Day 8, patients commence weekly KB004 infusions over 2 hours with standard premedications. Three cohorts are planned in this study (3.5mg/kg, 5.25 mg/kg, 7.9 mg/kg; additional dose levels may be explored based on toxicity, efficacy and biodistribution data as determined by the safety monitoring committee). On day 36, patients receive both 89ZrKB004 and KB004, allowing assessment of receptor occupancy to guide RPTD determination. Response rate (RANO) and survival data will be collected and patients benefiting may continue KB004 treatment until disease progression. Primary objective: to determine the toxicity and RPTD of KB004 in patients with advanced GBM. Secondary objectives: to determine the biodistribution and pharmacokinetics of 89ZrKB004; to determine frequency of EphA3 positive GBM in archival specimens and by 89ZrKB004 scans, and correlate with known biomarkers; to describe response rates per RANO criteria and pharmacodynamics following KB004 infusion; Exploratory objectives: to perform exploratory analysis between clinical outcomes and biodistribution/PK/PD data, including from matched biopsies.

NCT ID: NCT03363867 Not yet recruiting - Ovarian Cancer Clinical Trials

BEACON - Targeting the C1 Subtype of High Grade Serous Ovarian Cancer

Start date: February 1, 2018
Phase: Phase 2
Study type: Interventional

Epithelial ovarian cancer (EOC) is the ninth most common cause of cancer in Australian women, with an estimated 1500 new diagnoses in Australia in 2015, and remains the seventh most common cause of cancer death in Australian women. High grade serous ovarian cancer (HGSC) is the most common form of Epithelial Ovarian Cancer, and accounts for the most deaths due to a gynaecological cancer. The majority of women diagnosed with High Grade Serous Ovarian Cancer present with advanced disease, and are typically managed with a combination of cytoreductive surgery and platinum-based chemotherapy. Despite initial good response rates to chemotherapy, High Grade Serous Ovarian Cancer recurs in up to 70% of patients who present with Stage III/IV disease. The molecular characteristics of High Grade Serous Ovarian Cancer have recently been extensively described in multiple studies. One of the consistent features identified are four distinct molecular subtypes that are based on gene expression profiles.These four subtypes are associated with differential clinical outcome that are largely consistent across multiple datasets. The subtypes may also be predictive for benefit from certain types of treatment. The "C1" or mesenchymal subtype is pathologically characterised by an excessive fibrotic response of the stroma surrounding tumours, a process that is collectively referred to as desmoplasia. Patients with C1 High Grade Serous Ovarian Cancer have an increased incidence of primary treatment failure and poor overall survival (OS). The purpose of this research project is to test how safe and effective the combination treatment of cobimetinib, bevacizumab and atezolizumab is as a treatment for patients with a C1 subtype of platinum resistant or refractory ovarian, fallopian tube or peritoneal cancer. Cobimetinib is a drug that blocks a protein called Mitogen-activated protein kinase (MEK). MEK proteins are involved in the multiplication of cancer cells. By binding to the MEK protein, cobimetinib may help to stop the growth of your cancer cells. Bevacizumab is an antibody (a type of protein produced by the immune system) that is specifically designed to block a protein called Vascular Endothelial Growth Factor (VEGF). VEGF is a protein that can increase the growth of tumour cells and binding to VEGF may help to stop the growth of tumours. Atezolizumab is a type of drug called a Programmed Cell Death Protein 1 (PD-L1) inhibitor. PD-L1 binds to PD-1 which is a type of protein found on the surface of cells in your body's immune system, and it controls the ability of your body's natural immune response to trigger the death of tumour cells. Tumour cells can hide from the immune system by using PD-L1, which stops your immune system from triggering tumour cell death. Atezolizumab is a drug designed to block this PD-1/PD-L1 interaction by binding to PD-L1 so that PD-1 cannot bind to it and stops it from turning off your immune cells. This helps your immune system to recognise and destroy tumour cells. In turn, this potentially can stop or reverse the growth of your cancer. Cobimetinib, bevacizumab and atezolizumab have been used alone or in combination in the treatment of many other cancers. Each of them are individually licensed for the treatment of cancers such as advanced melanoma, non-small cell lung cancer, and bladder cancer in Australia. However, this treatment combination is experimental and is not approved to treat ovarian, fallopian tube or peritoneal cancers in any country.

NCT ID: NCT03361163 Not yet recruiting - Clinical trials for Bacterial Infections

Controlled Human Infection for Vaccination Against Streptococcus Pyogenes

Start date: December 2017
Phase: Phase 1
Study type: Interventional

Group A Streptococcus (GAS) infection is a major cause of death and disability globally with a disproportionately high burden in settings of disadvantage worldwide. Acute infections due to GAS range from very common superficial skin infections (>150 million prevalent cases) and pharyngitis (over 600 million incident cases) to life-threatening invasive disease (>600,000 incident cases) such as necrotising fasciitis. Post-infectious GAS sequelae of GAS include acute rheumatic fever (ARF, ~500,000 incident cases) leading to rheumatic heart disease (RHD, ~34 million prevalent cases), and acute glomerulonephritis. The health services impact of GAS disease in all its forms is immense and strikes at every level from primary to intensive care. Controlled human infection models (CHIMs) have a long history of critical contributions to vaccine development. Data from CHIMs meeting modern scientific, regulatory, and ethical standards, are aiding efforts to control over 25 major human pathogens, including bacteria (e.g. pneumococcus, cholera), viruses (e.g. respiratory syncytial virus, influenza), and parasites (e.g. malaria, schistosomiasis). A reliable and safe controlled human infection model of GAS pharyngitis will be an important part of the global vaccine development effort. To build the model, the investigators are undertaking a dose-ranging study using an observational, dose-escalation, inpatient trial to determine the dose of GAS administered by direct oropharyngeal inoculation (bacteria 'painted' onto throat) required to reliably produce a pharyngitis attack rate of ≥ 60% in carefully screened healthy adult volunteers.

NCT ID: NCT03349710 Recruiting - Clinical trials for Squamous Cell Carcinoma of the Head and Neck

Nivolumab or Nivolumab Plus Cisplatin, in Combination With Radiotherapy in Patients With Cisplatin-ineligible or Eligible Locally Advanced Squamous Cell Head and Neck Cancer

Start date: November 22, 2017
Phase: Phase 3
Study type: Interventional

This study has two, independent, cohorts, both in locally advanced squamous cell head and neck cancer. The purpose of the first cohort is to determine whether nivolumab in combination with radiotherapy is more effective than cetuximab in combination with radiotherapy, in subjects who are ineligible for cisplatin. The purpose of the second cohort is to determine whether nivolumab, cisplatin, and radiotherapy is more effective than cisplatin and radiotherapy in subjects who are eligible to receive cisplatin
