This phase 3 study is recruiting patients who have Essential Thrombocythemia (ET) who have an inadequate response to or are intolerant of hydroxyurea. This study will measure the safety and effectiveness of an inhibitor treatment called bomedemstat. Bomedemstat is an "investigational" (not yet FDA approved) treatment. The main purpose of the study is to how bomedemstat compares to BAT (best available therapy) as an effective treatment for ET. The study will enroll approximately 300 patients who will be randomly assigned 1:1 (like flipping a coin) to either bomedemstat or BAT. The study includes a screening phase, initial treatment phase, extended treatment phase, and posttreatment phase. The initial treatment portion of the study begins on study Day 1 and continues until the participant completes treatment at Week 52. The primary endpoint analysis will be performed on data from the first 52 weeks of treatment. Patients who have not discontinued study treatment at Week 52 will be eligible to continue receiving study treatment in the Extended Treatment Phase for up to Week 156. Patients in the BAT arm who have received a minimum of 52 weeks of treatment and discontinued study treatment due to intolerance/resistance/refractoriness/inadequate response (defined by the investigator as per the local product labels of BAT regimens) may be eligible to switch to the bomedemstat arm during the Extended Treatment Phase at the investigator's discretion (as per protocol defined eligibility to receive bomedemstat). Patients will continue treatment until disease progression, unacceptable toxicity, study closure, death, or withdrawal of consent. The main risk is that medical treatments often cause side effects. Patients may have none, some, or all of the side effects listed or not listed in the protocol, and they may be mild, moderate, or severe. There is no direct benefit for them in participating in this study.

This phase 3 study is recruiting patients who have myelofibrosis who have never had a JAK inhibitor. This study will measure the safety and effectiveness of a tumor protein inhibitor treatment called navtemadlin combined with another tumor protein inhibitor called ruxolitinib. Navtemadlin is an "investigational" (not yet FDA approved) treatment, Ruxolitinib is FDA approved. The main purpose of the study is to see if navtemadlin combined with ruxolitinib is an effective treatment for myelofibrosis. The study will enroll approximately 180 patients with each patient initially receiving ruxolitinib. The study includes a screening period, run-in period, and a randomized (like flipping a coin) add-on period. The first two periods will be over the course of 18-24 weeks while the randomized add-on period is for those whose treatment with ruxolitinib is not effective enough and will last for a different amount of time for each patient. In the run-in period after screening, patients will take ruxolitinib at the dose determined by their study doctor for 18-24 weeks. If treatment with ruxolitinib alone is not effective, the participate will be randomized into one of two groups. In the randomized add-on period, participants will either receive ruxolitinib with navtemadlin 240 mg or a matching placebo (a pill that contains no medicine) daily for one week out of the 28-day cycle in combination with ruxolitinib at a dose determined by their study doctor. Patients in this group will continue treatment until disease progression, unacceptable toxicity, study closure, death, or withdrawal of consent. The main risk is that medical treatments often cause side effects. Patients may have none, some, or all of the side effects listed or not listed in the protocol, and they may be mild, moderate, or severe. There is no direct benefit for them in participating in this study.

The main purpose of this study is to measure overall survival (OS) and safety of ivonescimab (study drug) when combined with chemotherapy drugs carboplatin, paclitaxel or nab-paclitaxel compared to pembrolizumab combined with chemotherapy drugs carboplatin, paclitaxel or nab-paclitaxel. Participants will undergo screening procedures done to determine if they meet the requirements to be in this study. Screening will be completed within 28 days before receiving the study drug. Many of these screening measures are likely part of regular cancer care and may be done even if it turns out that you do not participate in the research study.

Once enrolled in the study, participants will visit the clinic every three weeks for 4 cycles of ivonescimab plus chemotherapy or pembrolizumab and chemotherapy for up to four infusions, followed by ivonescimab or pembrolizumab every three weeks for up to 24 months. If a participant's physician decides to use nab-paclitaxel chemotherapy for the first 4 cycles of treatment, the schedule of treatment is different and will require that the participant comes to the clinic for this infusion on days 1, 8, and 15 of each cycle. There will be follow-up check-up visits with the study team approximately 7 days, 30 days and 90 days after the last treatment or before the participant starts a new treatment for the cancer. Ninety (90) days after the participant stops taking the study drug, there will be a call or a visit scheduled to review how the they are feeling. This is a survival call/visit and will happen every 90 days until the end of the study. Participation in this study will last about 4 years, 2 years in active treatment and 2 years in follow up.

This phase 3 study is recruiting patients who are at risk of graft-versus-host disease (GVHD) after a bone marrow transplant. This study will measure the safety and effectiveness of a prevention treatment combination called Tacrolimus/Methotrexate/Ruxolitinib compared to Standard of Care (SOC), Post-Transplant Cyclophosphamide/Tacrolimus/Mycophenolate Mofetil. Ruxolitinib (Rux) is an approved treatment for GVHD. This study is divided into two parts. The first part, called the run-in phase, will investigate the best dose of Ruxolitinib. The second part of the study will compare the SOC combination therapy with the investigational combination therapy (which will include Ruxolitinib). Participants will be randomly assigned to one of the two groups (like flipping a coin). The study will enroll up to 572 patients nationwide and 5 at MUSC. The participants can expect to be involved in the study for at least 24 months. The main risk is that medical treatments often cause side effects. The most common side effects expected from the investigational combination therapy are high cholesterol, increased liver enzymes, low platelet levels, and low red blood cell counts. There is no direct benefit for them in participating in this study.
