This invention provides methods to evaluate therapeutic efficacy of therapeutic monoclonal antibodies.

A method for detecting an immune cellular response including the steps of: (a) suctioning a defined amount of the sample by an automated suction/discharge device, (b) discharging this amount, using the device, into container R, containing, beforehand, at least one stimulant for secretion of the molecule by the at least one cell, or else not containing such a stimulant, (c) when the container does not contain the stimulant beforehand, introducing into container R the at least one secretion stimulant contained in container E, using the device, and (d) allowing the sample and stimulant to incubate, forming a mixture, by the at least one cell (i) in container R or (ii) in another container S after suctioning and discharge of the mixture using the device, and (e) detecting the immune cellular response, the detection of the immune cellular response indicates the presence of an immune cellular response specific for the stimulant.

The present invention relates to methods for efficiently generating recombinant monoclonal antibodies derived from B cells of a non-human host which has been immunochallenged with one or more target antigens. The methods comprise the steps of identifying and isolating B cell that bind to the antigen by FACS, and recombining and enriching for thousands of cells to create a B cell library. Related products and methods, such as methods of producing expression libraries, are also disclosed.

The disclosure provides a method for assessing the risk of potential adverse effects for a human patient mediated by the administration of a CD19CD3 bispecific antibody to said patient comprising determining the ratio of B cells to T cells of said patient. The disclosure also provides a method for administering a CD19CD3 bispecific antibody to a human patient having a B:T cell ratio of about 1:5 or lower, comprising administering doses in a dosing regimen. This dosing regimen can be applied in methods for treating malignant CD19 positive lymphocytes or for ameliorating and/or preventing an adverse effect mediated by the administration of said bispecific antibody. The Also provided is a pharmaceutical package or kit comprising a first dose and a second dose and optionally a third dose of said antibody.

The invention provides methods and compositions for perturbing gene expression in hematopoietic cell lineages in vivo.

Provided herein are methods for identifying a subject as a responder or non-responder to immune checkpoint blockade by detecting a B cell signature. Further provided herein are methods for treating cancer by administering immune checkpoint blockade therapy to a subject identified to have a B cell signature.

The presently disclosed subject matter relates to methods and compositions for determining synapse formation, e.g., synapse formation associated with the activity of multispecific antibodies such as T cell-dependent bispecific antibodies.

This invention concerns compositions and methods of treating or diagnosing inflammatory disorders and other disorders, as well as compositions and methods of treating HIV.

The present invention relates to compounds for use in treating a disease that is associated with (related to) CYP7B1 wherein the compound inhibits CYP7B1. The present invention further relates to a method of treating or preventing such a disease by administering an inhibitor of CYP7B1. The present invention also relates to a method of determining whether a compound is effective in treating or preventing a disease associated with the formation of inducible bronchus-associated lymphoid tissue (iBALT).

The present invention provides a method for determining whether a Rheumatoid Arthritis (RA) patient is susceptible to treatment with a B cell targeted therapy, which method comprises the step of analysing B cells and/or germinal centre-like structures (GC-LS) in a synovial tissue sample from the patient; wherein a patient whose synovial tissue sample is B cell rich and/or GC-LS negative is determined to be susceptible to treatment with the B cell targeted therapy, whereas a patient whose synovial tissue sample is B-cell poor and/or GC-LS positive is determined to be resistant to treatment with the B cell targeted therapy.
