This phase II trial studies how well talazoparib works for the treatment of breast cancer with a BRCA 1 or BRCA 2 gene mutation that has spread to other places in the body (metastatic). Talazoparib is a study drug that inhibits (stops) the normal activity of certain proteins called poly (ADP-ribose) polymerases also called PARPs. PARPs are proteins that help repair deoxyribonucleic acid (DNA) mutations. PARP inhibitors, such as talazoparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. PARPs are needed to repair mistakes that can happen in DNA when cells divide. If the mistakes are not repaired, the defective cell will usually die and be replaced. Cells with mistakes in their DNA that do not die can become tumor cells. Tumor cells may be killed by a study drug, like talazoparib, that stops the normal activity of PARPs. Talazoparib may be effective in the treatment of metastatic breast cancer with BRCA1 or BRCA2 mutations.

Study SPH4336-US-01 is an open-label (no placebo), multicenter clinical trial to evaluate the
safety, blood levels (pharmacokinetics) and preliminary anti-tumor effects of SPH4336, a
selective enzyme blocker, in patients with specific types of liposarcomas (tumors expressing
the target of the study drug).

Severe Aplastic Anemia (SAA) is a rare condition in which the body stops producing enough new
blood cells. SAA can be cured with immune suppressive therapy or a bone marrow transplant.
Regular treatment for patients with aplastic anemia who have a matched sibling (brother or
sister), or family donor is a bone marrow transplant. Patients without a matched family donor
normally are treated with immune suppressive therapy (IST). Match unrelated donor (URD) bone
marrow transplant (BMT) is used as a secondary treatment in patients who did not get better
with IST, had their disease come back, or a new worse disease replaced it (like leukemia).

This trial will compare time from randomization to failure of treatment or death from any
cause of IST versus URD BMT when used as initial therapy to treat SAA.

The trial will also assess whether health-related quality of life and early markers of
fertility differ between those randomized to URD BMT or IST, as well as assess the presence
of marrow failure-related genes and presence of gene mutations associated with MDS or
leukemia and the change in gene signatures after treatment in both study arms.

This study treatment does not include any investigational drugs. The medicines and procedures
in this study are standard for treatment of SAA.

This is a global, multicenter Phase 1/3 study to evaluate the efficacy and safety of
selinexor plus ruxolitinib in JAK inhibitor (JAKi) treatment-nave myelofibrosis (MF)
participants. The study will be conducted in two phases: Phase 1 (open-label) and Phase 3
(double-blind). Phase 1 (enrollment completed) was an open-label evaluation of the safety and
recommended dose (RD) of selinexor in combination with ruxolitinib and included a dose
escalation using a standard 3+3 design (Phase 1a) and a dose expansion part (Phase 1b). In
Phase 3, JAKi treatment-nave MF participants are enrolled in 2:1 ratio to receive the
combination therapy of selinexor + ruxolitinib or the combination of placebo + ruxolitinib.

This study is being conducted to evaluate the safety, tolerability, dose-limiting toxicity
(DLT) and determine the maximum tolerated dose (MTD) and/or recommended dose(s) for expansion
(RDE) of INCA033989 administered in participants with myeloproliferative neoplasms.

This phase II trial studies how well acalabrutinib works in treating patients with chronic graft versus host disease. Acalabrutinib may be an effective treatment for graft-versus-host disease caused by a stem cell transplant.

The goal of this clinical trial is to test a new drug plus standard treatment compared with
standard treatment alone in patients with advanced head and neck squamous cell carcinoma and
cholangiocarcinoma.

The main questions it aims to answer are:

- is the new drug plus standard treatment safe and tolerable

- is the new drug plus standard treatment more effective than standard treatment

This phase II trial tests whether nivolumab and ipilimumab works to shrink tumors in patients with liver cancer that has spread to nearby tissue or lymph nodes (locally advanced), has spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Nivolumab and ipilimumab may be effective in killing tumor cells in patients with liver cancer.
