Ruxolitinib

The goal of this clinical research study is to learn if the combination of ruxolitinib with cladribine and venetoclax can help to control the disease in patients with R/R T-PLL.

* To find the recommended dose of axatilimab given alone and in combination with ruxolitinib in patients with MF and CMML. * To learn if axatilimab given in combination with ruxolitinib can help to control MF and CMML.

This phase I trial studies the side effects and best dose of ruxolitinib (Rux) therapy alone (monotherapy) followed by Rux plus azacitidine (AZA) maintenance therapy and to see how well it works in treating patients with acute myeloid leukemia (AML) who are undergoing reduced intensity allogeneic hematopoietic stem cell transplantation (alloHSCT). AlloHSCT provides the only chance for cure for many patients with AML. AlloHSCT is a procedure in which a person receives blood-forming stem cells (cells from which all blood cells develop) from a genetically similar, but not identical, donor. This is often a sister or brother, but could be an unrelated donor. One of the common reasons for death after an alloHSCT is graft versus host disease (GVHD), which occurs when the transplanted cells from the donor attacks the recipient's normal cells. Ruxolitinib is in a class of medications called kinase inhibitors. It works to treat GVHD by blocking the signals of the cells that cause GVHD. Azacitidine is in a class of medications called demethylation agents. It works by helping the bone marrow to produce normal blood cells and by killing abnormal cells in the bone marrow. Giving Rux after the transplant may stop GVHD from occurring. Maintenance therapy with AZA, may help prevent or delay cancer from coming back. Giving Rux monotherapy followed by Rux plus AZA maintenance therapy may be safe, tolerable, and/or effective in treating patients with AML who are undergoing alloHSCT.

This phase I trial studies the side effects and best dose of ruxolitinib when given together with venetoclax and compares the effect of ruxolitinib in combination with venetoclax to venetoclax and azacitidine in treating patients with acute myeloid leukemia (AML) that has come back (relapsed) or has not responded to treatment (refractory). Ruxolitinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Azacitidine stops cells from making deoxyribonucleic acid and may kill cancer cells. It is a type of antimetabolite. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving ruxolitinib in combination with venetoclax and azacitidine may be safe, tolerable, and/or effective compared to ruxolitinib with venetoclax in treating patients with relapsed or refractory AML.

This study will test if adding ruxolitinib to standard multi-drug chemotherapy regimen will be safe and tolerated in adolescents and young adults with newly diagnosed Ph-like acute lymphoblastic leukemia (ALL).

This phase I trial studies the best dose and side effects of recombinant vesicular stomatitis virus (VSV) carrying the human (h) sodium iodide symporter (NIS) and Interferon (IFN) beta (β) genes (VSV-hIFNβ-NIS) in combination with cemiplimab in patients with T-cell lymphoma. A virus, called VSV-hIFNβ-NIS, which has been changed in a certain way, may be able to kill cancer cells without damaging normal cells. Immunotherapy with ipilmumab and cemiplimab may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread.
