Methods are provided for monitoring treatment of a subject using heparin therapy or a ligand, such as an CD20 or CD52 antibody, that binds to a cellular marker and to which the subject may develop masking reactions or auto-antibodies that inhibit evaluation of treatment. The methods involve adding to a single container a sample containing cells that express the cellular target with (i) a soluble ligand that binds the cellular target, (ii) a soluble ligand that binds the soluble analyte or a competing soluble analyte; and (iii) a capture medium that binds directly to the soluble analyte, indirectly to the soluble analyte, or to the soluble ligand that binds to the soluble analyte. Complexes formed in the container by interaction of these components are substantially simultaneously analyzed and quantitated without physically separating the complexes. Kits for performing the assays are also provided.

A solid drug core insert can be manufactured by injecting a liquid mixture comprising a therapeutic agent and a matrix precursor into a sheath body. The injection can be conducted at subambient temperatures. The mixture is cured to form a solid drug-matrix core. The therapeutic agent can be a liquid at about room temperature that forms a dispersion of droplets in the matrix material. A surface ofthe solid drug core is exposed, for example by cutting the tube, and the exposed surface of the solid drug core releases therapeutic quantities of the therapeutic agent when implanted into the patient. In some embodiments, the insert body inhibits release of the therapeutic agent, for example with a material substantially impermeable to the therapeutic agent, such that the therapeutic quantities are released through the exposed surface, thereby avoiding release of the therapeutic agent to non-target tissues.
