This is a Phase 1, open-label, international, dose escalation study to evaluate the safety of \[225Ac\]Ac-PSMA-617 (225Ac-PSMA-617) in men with PSMA-positive prostate cancer who have and have not had prior exposure to \[177Lu\]Lu-PSMA-617 (177Lu-PSMA-617) or \[177Lu\]Lu-PSMA I\&T (177Lu-PSMA I\&T).

Researchers in this study want to compare how well drug radium-223 dichloride (Xofigo) and new (novel) anti-hormonal (NAH) therapy work in participants with prostate gland cancer which has spread to the bone and progressed on or after one line of NAH therapy. Meanwhile researchers want to compare the safety of radium-223 dichloride and NAH therapy. Radium-223 dichloride is known as a radioactive drug that is taken up by bones after it is injected into the body. It works by giving off a type of radioactivity that travels a very short distance and kills the tumor cells that have spread to the bone without major effects to the healthy cells. It has been approved in many countries for the treatment of patients with prostate cancer which has spread to the bone. The NAH drugs used in this study will be either abiraterone acetate (Zytiga) (plus prednisone/prednisolone) or enzalutamide (Xtandi). Both of them are standard approved medications which are used in the treatment of advanced prostate cancer. Participants in this study will receive either Radium-223 dichloride or a NAH therapy. Radium-223 dichloride will be given as an infusion into one of the veins on Day 1 of each 4-week cycle for a total of up to 6 cycles. Oral NAH therapy will be given per the standard approved dose once daily until the disease has progressed. Participants will visit the hospital or clinic every 2 weeks for the first 6 cycles, and only on the first day of each cycle from cycle 7 and onwards. Observation for each participant will last for about 2 years in total. Blood and urine samples will be collected from the participants and participants will be asked to complete questionnaires about the well-being and the pain.

Pancreatic head malignancies are aggressive cancers that are often inoperable when they are diagnosed. In the \~20% of patients who are diagnosed when the disease is still operable, surgery is the only treatment that can provide a chance of cure. Unfortunately, up to 75% of patients undergoing surgery will have the cancer come back (recur). One of the reasons for this is the challenge of removing the whole tumour with some surrounding non-cancerous tissue to ensure that every tumour cell has been removed. This is difficult because there are many structures very close to the pancreas (such as the blood vessels that supply the intestines) that cannot be removed. A recent review study of \>1700 patients who had a Whipple's operation (the cancer operation that is performed to remove the head of pancreas) and found that whilst the majority of patients had cancer recurrence in distant sites (like the liver) that would not be affected by how the operation was performed, 12% of patients had the cancer recur just at the site of where the operation had been; this is known as 'local' recurrence. This suggests that a small amount of cancer was not removed at the time of surgery in these patients. Very few studies have looked at the relationship between the Computerised Tomography (CT) scan before surgery and the histology results (information about the tumour after it has been examined under the microscope) and whether this can predict exactly where the tumour recurs. If investigators can find factors that predict which patients get local only recurrence, investigators may be able to offer improved surgical techniques or other therapies during or immediately after the operation to these patients, hopefully leading to improved cure rates. This retrospective international study will look at these factors in patients who underwent a Whipple's operation for pancreatic cancer, bile duct cancer or ampullary cancer over a three year period between 2012 and 2015. Participating centres will provide data on pre-operative scans, complications around the time of surgery, any therapies (e.g. chemotherapy) that the patients had and if and where the cancer recurred. With this information, investigators hope to find ways to predict which patients will get local-only recurrence, so researchers can select them for future studies to see if additional treatments can improve the chance of cure from surgery for these patients.

This study compares 2 medicines for type 2 diabetes: semaglutide (new medicine) and a dummy medicine (placebo). Semaglutide will be tested to see how well it works compared to the dummy medicine. The study will also test if semaglutide is safe in children and teenagers. Participants will either get semaglutide or the dummy medicine - which one is decided by chance. Participants will take 1 tablet of the study medicine every morning on an empty stomach. They have to wait 30 minutes before they eat, drink or take any other medication by mouth. The study will last for about 1 year and 3 months (66 weeks). Participants will have 12 clinic visits and 8 phone calls with the study doctor. At all 12 clinic visits, participants will have blood samples taken. Participants will also be asked some questions.

Immune-checkpoint inhibitors have recently become available as a new therapy for a variety of cancers. This drugs function by boosting the anti-cancer immune response, but unfortunately, may cause off-target, non-specific immune activation, resulting in liver and gut toxicity. In order to understand the development of liver immune-related adverse events we aim to collect full clinicopathological data from patients with advanced lung cancer treated with immune-checkpoint inhibitors at Blacktown, Westmead and Nepean Hospitals. Patients treated with standard chemotherapy will be used as a control group. This study aims to establish clinical risk factors that can predict the occurrence of liver immune-related adverse events in patients with advanced lung cancer treated with immune-checkpoint inhibitors. Such predictors may assist in the stratification of patients based on their risk for development liver toxicity as a result of immunotherapy, allowing early cessation/modification of treatment prior to the development of severe adverse reactions. In addition, this retrospective study will aim to determine the significance of pre-existing liver damage on the development of liver adverse events as well as establish a timeline defining the development of adverse events in the liver.

Normal heart function involves rhythmic contraction of all four chambers of the heart and this rhythm is maintained by the electrical wiring (conduction system) of the heart. Abnormality in this system results in either very slow or very fast heart rates leading to insufficient blood supply to the body due to inefficient pumping of the heart. cardiac resynchronization therapy pacemaker and cardiac resynchronization therapy defibrillator devices are used to synchronise heart function. The purpose of this study is not only to determine the pattern of electrical wiring of the heart and identify the variations seen in individuals with heart failure, but also, to explore the benefits of different types of pacing using CRT devices.

This study will evaulate the long-term safety, efficacy and pharmacokinetics (PK) of recombinant human pentraxin-2 (rhPTX-2; PRM-151) zinpentraxin alfa, administered by intravenous (IV) infusion to participants with idiopathic pulmonary fibrosis (IPF).

This phase 1 study will investigate the safety, tolerability, pharmacokinetic, pharmacodynamic, and clinical activity of AZD0486, a CD19 x CD3 T-cell engaging bispecific antibody, in subjects with B-cell non-Hodgkin lymphoma (B-NHL).

The primary objective of this study is to evaluate the effect of brensocatib at 10 mg and 25 mg compared with placebo on the rate of pulmonary exacerbations (PEs) over the 52-week treatment period.
