Subdural hematoma (SDH) is a common condition experienced after head injury. Blood collects on the surface of the brain, causing headaches which can progress to confusion, weakness, or even coma. While patients with SDH often receive surgery, not all patients require surgery right away to ease pressure on the brain. After surgery, there can be up to 30 percent chance of more bleeding and the need for more surgeries. Given this, a drug capable of lowering the chance of more bleeding and speeding the recovery of the patient is highly desirable. In this study, we will test a commonly used, cheap drug called Tranexamic Acid (TXA). While the body stops unwanted and sometimes dangerous bleeding naturally by forming blood clots, TXA stops these blood clots from breaking down, which helps to keep bleeding spots plugged. Our previous study showed that TXA helped speed up patients' recovery; but a larger number of patients is necessary to evaluate how well TXA works to reduce bleeding and improve patient-reported outcomes. In this study, regardless of the need for surgery, half of the patients will be randomly assigned to take TXA, while the other half will take a placebo, which is a look-alike substance that contains no active drug. We will measure multiple outcomes over time to determine if TXA is working and lowers healthcare and personal costs, while also taking blood and surgical samples, to better understand how this drug works in SDH patients.

The goal of this phase 2 clinical trial is to learn if the three treatments olaparib, durvalumab and bevacizumab can treat participants with a diagnosis of stage 4 high grade serous ovarian cancer that is too advanced to undergo upfront surgery.
The main questions it aims to answer are:
Is the treatment able to shrink the cancer sufficiently for participants to undergo surgery? Is the combination of treatments safe in this neoadjuvant (before surgery) setting? This is a single arm study with no comparator arm.
Participants will receive the treatment up to 3 cycles with each drug given as follows in a 28-day cycle:
Olaparib orally on a twice daily continuous dosing schedule Durvalumab given intravenously on day 1 Bevacizumab given intravenously on day 1 and 15 (Day 15 omitted in C3)
Participants will be assessed throughout the study for safety and efficacy endpoints

This is a dose-finding study of oral zelenirstat (PCLX-001) in patients with R/R AML. There are two parts to the study: Dose Escalation and Dose Expansion.
