Aspects of the invention described herein relate to synthetic compounds that are useful for targeting and labeling tumor cells so as to facilitate recognition by binding agents including Chimeric Antigen Receptor T cells (CAR T cells), which are administered to a subject by intravenous or locoregional administration. Several compositions and methods of making and using these compositions to treat or inhibit a disease in a subject are contemplated.

Some embodiments of the methods and compositions provided herein relate to the use of hapten labeled cells to stimulate chimeric antigen receptor (CAR) T cells. In some embodiments, CAR T cells can include a CAR that specifically binds to a hapten. Some embodiments relate to the in vivo or in vitro stimulation CAR T cells by hapten labeled cells.
The disclosure generally relates to the preparation of representative samples from clinical samples, e.g., tumors (whole or in part), lymph nodes, metastases, cysts, polyps, or a combination or portion thereof, using mechanical and/or biochemical dissociation methods to homogenize intact samples or large portions thereof. The resulting homogenate provides the ability to obtain a correct representative sample despite spatial heterogeneity within the sample, increasing detection likelihood of low prevalence subclones, and is suitable for use in various diagnostic assays as well as the production of therapeutics, especially "personalized" anti-tumor vaccines or immune cell based therapies.
