Abstract
Provided are methods for administering multiple doses of cells, such as T cells, to subjects for cell therapy. Also provided are compositions and articles of manufacture for use in the methods. The cells generally express recombinant receptors such as chimeric receptors, e.g., chimeric antigen receptors (CARs) or other transgenic receptors such as T cell receptors (TCRs). The methods generally involve administering a first and at least one consecutive dose of the cells. Timing of the doses relative to one another, and/or size of the doses, in some embodiments provide various advantages such as lower or reduced toxicity and improved efficacy, for example, due to increased exposure of the subject to the administered cells. In some embodiments, the first dose is a relatively low dose, such as one that reduces tumor or disease burden, thereby improving the efficacy of consecutive or subsequent doses, and the consecutive dose is a consolidating dose.
