Clinical trials

This trial is a single arm study for patients receiving bevacizumab for IDH-wildtype glioblastoma. Patients receiving bevacizumab (an anti-VEGF therapy) will receive PSMA scans to investigate the role of PSMA expression in glioblastoma and its relationship to VEGF expression.

The goal of this naturalistic, open label, single arm intervention study is to investigate the effects of Esketamine in treating depression.The main aims to answer are: * to investigate whether Esketamine is effective when added to ongoing antidepressant treatment * to identify patient characteristics that will determine a therapeutic response to Esketamine in real-world practice Participants will: * attend the clinic for supervised self-administration of intranasal Esketamine treatment * be observed for 2 hours following Esketamine administration including blood pressure monitoring * be asked to complete a battery of questionnaires * be reimbursed for travel expenses

Intracavitary brachytherapy for gynaecological cancer currently use cylinder-type applicators or custom wax moulds to place a radioactive source in close proximity to the treatment area and provide highly conformal dose distributions. This study is a Phase IIa non-randomised interventional pilot trial that will investigate the feasibility of successfully treating patients with 3D-printed custom applicators.

The aim of the study is to determine if single fraction dose escalated palliative radiotherapy results in a prolonged duration of benefit for patients otherwise suitable for Multifraction (5-10#) palliative radiation. The primary endpointis to determine the percentage of patients who have achieved a substantial benefit from palliative radiotherapy and have not redeveloped symptoms by 12 months post treatment

To examine the feasibility, safety and toxicity of focal stereotactic radiation treatment (SBRT) for locally recurrent prostate cancer.

Pelvis Adaptive radiotherapy (ART) is a two phase study looking at using adaptive radiotherapy to help reduce toxicity for cancer patients having radiotherapy in the pelvic region. Adaptive radiotherapy is a new technology that provides the ability to account for daily changes in anatomy. Adaptive radiotherapy also provides a foundation for which radiotherapy margins might be safely reduced. Phase 1 of this study is looking to see if a radiation therapist centred adaptive workflow can be implemented. If phase 1 of this study is safe and feasible, the study will proceed to phase 2. Phase 2 of the study looks at using adaptive technology to reduce radiation treatment margins. The primary aim of this study is to see whether margin reduced treatment using adaptive radiotherapy can reduce side effects for patients with cancer in the pelvic area.

Prostate ART is a two phase study looking at using adaptive radiotherapy to help reduce toxicity for prostate cancer patients. Adaptive radiotherapy is a new technology that provides the ability to account for daily changes in anatomy. Adaptive radiotherapy also provides a foundation for which radiotherapy margins might be safely reduced. Phase 1 of this study is looking to see if a radiation therapist centred adaptive workflow can be implemented. If phase 1 of this study is safe and feasible, the study will proceed to phase 2. Part 2 of the study looks at using adaptive technology to reduce radiation treatment margins. The primary aim of this study is to see whether margin reduced treatment using adaptive radiotherapy can reduce side effects for prostate cancer patients.

LOCATOR is a multicentre phase II randomised clinical trial that is looking at the process of contouring in radiation treatment for breast cancer patients. This study looks at whether contouring aided by artificial intelligence (AI) is comparable in quality to that of contouring done completely manually by a radiation oncologist. We are also looking at whether AI assisted contouring saves radiation oncologists time when compared to fully manual contouring. LOCATOR uses the LOCATOR software which is an in-house software developed locally and trained on local data.

The goal of this prospective clinical trial is to determine if HPV-associated oropharyngeal squamous cell carcinoma that is non-hypoxic on FMISO PET can be successfully treated with a lower dose of radiation therapy. The main questions it aims to answer are: 1. What is the pathologic complete response rate in patients selected for radiation dose de-escalation and neck dissection? 2. What is the correlation between MRI and FMISO PET assessment of hypoxia before and during RT? 3. What are the acute and late toxicities in patients selected for radiation dose de-escalation? 4. What are the quality of life scores in patients selected for radiation dose de-escalation? 5. What are the local, regional and distant failure rates of patients selected for radiation dose de-escalation? Patients with cT1-2N1-2b (AJCC 7th edition) oropharyngeal tumours will undergo surgical resection of the primary tumour. Following this, they will be allocated to standard radiation therapy (70Gy with concurrent cisplatin chemotherapy) or de-escalation radiation therapy (30Gy with concurrent cisplatin chemotherapy) based on the results of FMISO PET. Patients with non-hypoxic tumours at baseline OR after two weeks of radiation therapy will be allocated to the de-escalated group. 3-4 months after completion of radiation therapy, all patients in the de-escalated group will undergo mandatory neck dissection to assess pathologic response. Researchers will assess the pathologic response rate after surgery in the de-escalation group. They will also compare the outcomes (oncological outcomes and quality of life) between the group receiving the standard treatment (70Gy) and the group receiving de-escalated radiation therapy (30Gy).

This study is a 2-arm, double blinded, randomised clinical trial where 40 participants will be assigned 1:1 to insulin treatment alone (control) or insulin treatment and tirzepatide treatment for 32 weeks. The primary objective is to demonstrate that tirzepatide treatment, dose incremented to 15mg QW for 32 weeks adjunctive to insulin treatment can reduce body weight in patients with T1D and overweight or obesity when compared to insulin treatment alone. The secondary objective is to demonstrate that tirzepatide treatment, dose incremented to 15mg QW for 32 weeks can improve glycaemic control (measured by hbA1c), improve time in range, reduce insulin requirements, and reduce the severity of comorbidities in people with obesity and T1D. This trial includes a 6 month follow-up period.
