Abstract
Disclosed herein are methods of selecting an allogeneic T cell line for therapeutic administration to a patient having or suspected of having a pathogen or cancer. Also disclosed are methods of selecting a donor from whom to derive an allogeneic T cell line for therapeutic administration to a patient having or suspected of having a pathogen or cancer.
Claims18
A method of treating a human patient having or suspected of having (i) a pathogen that is cytomegalovirus (CMV) and symptoms of an infection by the pathogen or (ii) a cancer that is an Epstein-Barr virus (EBV)-positive post-transplant lymphoproliferative disorder, comprising:
- (a) selecting an allogeneic T cell line for therapeutic administration to the patient according to a method comprising:
- selecting a T cell line allogeneic to the patient that recognizes at least one epitope of an antigen of the pathogen or the cancer, using a representation that (i) identifies a plurality of HLA alleles and optionally HLA allele combinations, and (ii) discloses indications of relative activities of T cell lines, each recognizing at least one epitope of an antigen of the pathogen or cancer, and restricted to different ones of the HLA alleles or HLA allele combinations in the plurality;
- wherein in the representation each identified HLA allele or HLA allele combination is associated with the respective indication of relative activity of the T cell line restricted to the HLA allele or HLA allele combination, the relative activities being relative measures of known activity against the pathogen or against the cancer exhibited by the T cell lines, wherein the relative activities are in vivo clinical efficacies of the T cell lines in treatment of human patients having the pathogen or cancer, wherein each indication of relative activity is based on clinical data from a population of human patients;
- wherein
- (A) the T cell line selected has in common with the patient or diseased cells in the patient the HLA allele or HLA allele combination identified by the representation to which the recognition of the T cell line is restricted;
- and
- (B) the HLA allele or HLA allele combination, to which the T cell line selected is restricted, is associated in the representation with an indication of the highest relative activity among the HLA alleles and HLA allele combinations in the representation that are known to be in common with the patient or the diseased cells in the patient and are not otherwise disqualified;
- (b) generating the representation prior to the selecting step;
- (c) measuring the relative activities prior to the generating step;
- and
- (d) administering a population of T cells derived from the selected allogeneic T cell line to the patient.

- wherein the representation has been determined by a process comprising generating the representation prior to the selecting step, and measuring the relative activities prior to the generating step;
- wherein
- (A) the T cell line selected has in common with the patient or diseased cells in the patient the HLA allele or HLA allele combination identified by the representation to which the recognition of the T cell line is restricted;
- and
- (B) the HLA allele or HLA allele combination, to which the T cell line selected is restricted, is associated in the representation with an indication of the highest relative activity among the HLA alleles and HLA allele combinations in the representation that are known to be in common with the patient or the diseased cells in the patient and are not otherwise disqualified;
- and
- (b) administering a population of T cells derived from the selected allogeneic T cell line to the patient.
