The instant invention relates to combinations of the compound of formula (I) or pharmaceutically acceptable salts thereof with other active pharmaceutical ingredients ##STR00001##
pharmaceutical compositions comprising them, and their use as medicaments, particularly for the treatment of hematological malignancies.

Disclosed is the use of a water-soluble realgar solid dispersion in the preparation of an erythroid differentiation inducer for bone marrow hematopoietic stem cells and/or bone marrow hematopoietic progenitor cells. The water-soluble realgar solid dispersion is prepared from raw materials comprising 1 part by weight of realgar, 1-20 parts by weight of a polymer, and 0-5 parts by weight of a surfactant. The water-soluble realgar solid dispersion can induce bone marrow hematopoietic stem and/or progenitor cells to be differentiated into red blood cells, promote the accumulation of red blood cells in bone marrow cells, effectively alleviate the decrease in the number of red blood cells caused by the suppression of the erythroid differentiation of bone marrow hematopoietic stem and/or progenitor cells, improve anemia caused by hematopoietic failure, and protect bone marrow cells from the killing effect.

Disclosed herein are methods of treating minimal residual cancer in a subject. The methods involve contacting disseminated cancer cells (DCCs) in a subject with a bone morphogenic protein 7 (BMP7) derivative protein, where the contacting induces or maintains dormancy in the contacted DCCs of the subject to treat minimal residual cancer in the subject. Also disclosed are methods that involve contacting DCCs in a subject with a protein kinase RNA-like endoplasmic reticulum kinase (PERK) inhibitor selected from LY2, LY3, and LY4, where said contacting eradicates DCCs in the subject to treat minimal residual cancer in the subject.

The present invention relates to the treatment of Pin1-associated disorders (e.g., disorders characterized by elevated Pin1 activity) with arsenic trioxide, optionally in combination with a retinoic acid compound. Pin1-associated disorders may include, for example, proliferative disorders (e.g., cancers), inflammatory conditions, and autoimmune disorders associated with aberrant levels of Pin1 activity.

The present invention relates to treating malignancies such as tumors or cancers by orally administering lyophilized compositions comprising arsenic to a subject in such need. Malignancies include various hematological malignancies, such as acute myeloid leukemia (AML) including acute promyelocytic leukemia (APL), myelodysplastic syndrome (MDS), multiple myeloma (MM) and lymphomas and solid tumors including glioblastoma multiforme and breast cancer. This invention relates to a novel formulation comprising a lyophilized compositions comprising arsenic. The present invention also relates to a method for lyophilizing the arsenic trioxide, preparing the oral formulation comprising lyophilized compositions comprising arsenic, and a method for treating a subject with malignancies using the oral formulation.
