Adoptive T cell therapy represents an attractive modality for the treatment of patients with cancer. Peripheral blood mononuclear cells have been used as a source of antigen specific T cells but the very low frequency of T cells recognizing commonly expressed antigens such as NY-ESO-1 limit the applicability of this approach to other solid tumors. To overcome this, we tested a strategy combining IL-21 modulation during in vitro stimulation with first-in-class use of tetramer-guided cell sorting to generate NY-ESO-1 specific cytotoxic T lymphocytes (CTL).
CTL generation was evaluated in 6 patients with NY-ESO-1 positive sarcomas, under clinical manufacturing conditions and characterized for phenotypic and functional properties.
Following in vitro stimulation, T cells stained with NY-ESO-1 tetramer were enriched from frequencies as low as 0.4% to >90% after single pass through a clinical grade sorter. NY-ESO-1 specific T cells were generated from all 6 patients. The final products expanded on average 1200-fold to a total of 36 billion cells, were oligoclonal and contained 67-97% CD8+, tetramer+ T cells with a memory phenotype that recognized endogenous NY-ESO-1.
This study represents the first series using tetramer-guided cell sorting to generate T cells for adoptive therapy. This approach, when used to target more broadly expressed tumor antigens such as WT-1 and additional Cancer-Testis antigens will enhance the scope and feasibility of adoptive T cell therapy.

The use of antigen-specific T cells for adoptive immunotherapy of patients with advanced cancers is emerging as a promising treatment modality -. Recent trials using genetic modification of T cells to introduce chimeric antigen receptors (CAR's) or T cell receptors (TCR's) and redirect their target specificity to tumor cells can be remarkably effective in reducing tumor burden and providing durable remissions in B cell malignancies and some solid tumors -. However, the regulatory and logistical hurdles of gene transfer can be prohibitive and issues such as receptor mispairing (for TCRs), target antigen affinity, and serious, occasionally life-threatening, even lethal on-target toxicities remain to be fully addressed ,. Although once fully characterized, these genetically modified approaches may be quite expedient, they first require a priori possession of the relevant receptor sequence from the cognate antibody for a CAR or a T cell clone for a TCR as well as rigorous validation, all of which limit the flexibility of this approach and incur significant obstacles to bringing a cell product to the clinic.
An alternative approach, involves the isolation of circulating endogenous antigen-specific T cells from the peripheral blood (Endogenous T Cell Therapy or ETC) and ex vivo expansion for adoptive transfer. Although these tumor-reactive T cells can be present at very low frequency, the feasibility of isolating and expanding endogenous antigen-specific CTL from the peripheral blood of patients for adoptive therapy has been demonstrated in trials targeting melanocyte antigens such as gp100 and MART-1 in melanoma, with intriguing evidence of clinical efficacy ,. The endogenous frequency of CTL targeting melanocyte antigens such as MART-1 is particularly high (up to 1%) enabling facile generation of MART-1-specific T cells using conventional approaches ,,. However, for more commonly expressed tumor antigens such as WT-1, MAGE family antigens and NY-ESO-1, the generation of antigen-specific cytotoxic T lymphocytes (CTL) has been labor and resource-intensive and largely unsuccessful on a routine basis due to their relatively rare endogenous precursor frequencies (<1:10,000).
With the exception of MART-1 and some tumor-associated viral antigens, generation of antigen-specific T cells using a conventional approach involving repeated cycles of autologous PBMC stimulation using peptide-pulsed dendritic cells (DC's) often fails to enrich low frequency tumor-reactive CTL to numbers sufficient for expansion and adoptive transfer.
To address this issue, we previously discovered that the addition of IL-21 during the initial priming period could increase the total number of antigen-specific CD8 T cells by >20-fold and, at the clonal level, enrich for a population of high-affinity CD8 T cells with sustained elevation of CD28 levels and a helper-independent phenotype. This enrichment can be further enhanced by depletion of CD25+ Treg cells from the responder PBMC prior to in vitro stimulation -, leading to a synergistic increase in the yield of antigen-specific CTL to 2-300 fold greater than those cultures that were CD25 replete and not exposed to IL-21 ,.
Therefore, to broaden the scope of patients eligible for adoptive therapy and the tumors that can be treated, we chose to target a prototypic cancer-testis antigen, NY-ESO-1, expressed by several solid tumor malignancies, including breast cancer, lung cancer, melanoma, sarcoma and ovarian cancer. We developed a strategy where NY-ESO-1 specific T cells were first enriched through in vitro stimulation of CD25 depleted PBMC  with peptide pulsed dendritic cells in the presence of IL-21, followed by tetramer guided cell sorting to isolate and expand autologous NY-ESO-1-specific CTL from the peripheral blood of patients with sarcoma under clinically compliant manufacturing conditions.
To determine whether highly avid, oligoclonal NY-ESO-1 specific CD8+ T cells recognizing NY-ESO-1 positive tumor cell lines could be consistently isolated from patients who might benefit from NY-ESO-1 targeted therapy, we focused on patients with synovial sarcoma (SS) and myxoid/round cell liposarcoma (MRCL) because these tumors homogenously express NY-ESO-1, often with high intensity ,. We successfully isolated NY-ESO-1 specific T cells from 6 of 6, NY-ESO-1 expressing sarcoma patients using a clinical grade INFLUX cell sorter (Becton Dickson) and propagated these highly enriched populations to sufficient numbers for adoptive immunotherapy.

The flow sorted NY-ESO-1-specific T cells were then stimulated with anti CD3 mAb in T25 flasks, which yielded an average of 197 × 106 (range 73 to 331 × 106) T cells after 14 days. Larger volume expansions were then performed in either GREX containers or cell culture bags in the CPF. For two of the patients (#4 and #6), we performed the large volume expansion on T cells sorted from only a fraction of the positive wells. The average bag or GREX REP produced a 1204-fold expansion (range 650-1754 fold). All cell products were expanded to over 2 × 1010 cells, and except for patient #5, the final cell product was >85% CD8+ and NY-ESO-1 tet+ (range 67.2-97.1%) (Table 2 and Additional file 1: Figure S2). Based on these percentages, the absolute number of antigen specific CD8+, tet+ cells in each product ranged from 16.7 × 109 to 54.7 × 109. Cell doses in prior studies performed by our program that have led to clinical responses used 1010 cells/m2, suggesting this strategy for isolating and expanding NY-ESO-1 specific T cells can yield therapeutically relevant cell doses.
Phenotype and function of NY-ESO-1-specific CD8+ T cells
Exposure to IL-21 during in vitro priming has previously been shown to enrich for a population of CD8+ T cells with high affinity recognition of tumor antigen, effector function, and expression of co-stimulatory molecules such as CD28 ,. Phenotype analysis of the final expanded NY-ESO-1 specific T cell products demonstrated expression of CD45RO, CD27 and CD28 on the majority of CD8+ T cells, and the absence of CCR7 or CD62L, consistent with an effector memory like phenotype. In almost all cases, a subpopulation of CD127hi also appears in the final T cell product also suggesting a memory-like phenotype (see Additional file 1: Figure S3).
Thus, the avidity and effector function of antigen-specific CTL derived from the peripheral blood is sufficient to recognize endogenous tumor associated antigens and compares favorably to a clinically relevant high affinity mutant TCR. In order to confirm that NY-ESO-1 specific cells could be generated in patients without NY-ESO-1 expressing tumors, we also made cells through this process in two healthy donors which were also able to recognize peptide pulsed T2's and endogenously expressed peptide.
Clonality of products
We next assessed the clonality of the T cell products using TCR Vβ spectratyping. All products were oligoclonal with a range of high intensity peaks from 2 (patient #2) to 15 (patient #4) (Additional file 1: Figure S6). In order to better quantify the TCR composition of these products, deep sequencing of the TCR was performed on patient #1 and patient #4 (Adaptive Biotechnologies). Despite the fact that the cell product from patient #1 was comprised of tetramer positive T cells sorted and expanded from 3 individual 48 wells, the final cell product was almost entirely comprised of a single dominant clone constituting 86.3% of the TCR sequence reads. The next 5 most common sequences comprised 7.3% of the total sequences observed. A total of 235 were observed in the infusion product (Additional file 1: Figure S7). The product from patient #4 combined 4 wells and also contained a dominant clone (85.4% of the sequences). The next most common 6 clones comprised 9.05% of the product and a total of 435 sequences were observed. In composite, our data demonstrates the feasibility and reproducibility of generating a single clone dominant but still oligoclonal, tumor-reactive, NY-ESO-1 specific CD8+ -T cells from sarcoma patients using clinical cell sorting technology.
In light of the significant clinical responses observed among patients receiving antigen-specific T cells recognizing melanoma and leukemia-associated antigens, a means to target more commonly expressed tumor-associated antigens using a method that is relatively expedient and clinically feasible would be desirable. To this end, we developed a clinically-approved approach to isolate endogenous antigen-specific T cells from the peripheral blood for adoptive therapy ("endogenous T cell" or ETC therapy). An unbiased source of T cells would be readily available from the peripheral blood in contrast to TIL therapy (where a surgically accessible tumor with an adequate population of infiltrating lymphocytes is required), In contrast to engineered TCR or CAR, no genetic modification is required and there is greater flexibility in targeting tumor-associated antigens. With ETC therapy, more rapid implementation of clinical studies is also possible since the only requirement is a new GMP-grade peptide whereas specific toxicities and binding properties associated with each new TCR or CAR construct need to be addressed. To demonstrate the feasibility of the form of ETC therapy presented in this study, we target a prototypic cancer testis antigen (CT antigen), NY-ESO-1, expressed in several solid tumor types including breast, colorectal, ovarian, lung cancer and sarcoma.
Patients with soft tissue sarcomas can express very high levels of NY-ESO-1 but the often undetectable levels of NY-ESO-1 specific CD8+ T cells in their peripheral blood has made it difficult to generate autologous NY-ESO-1 T cell products for adoptive immunotherapy. Here we demonstrated that after stimulating CD25 depleted T cells from sarcoma patients with autologous dendritic cells pulsed with the NY-ESO-1157-165 peptide and in vitro exposure to IL-21, rare wells containing measurable tetramer positive T cells can be identified and clinical grade cell sorting can be used to enrich and expand these populations to large numbers of highly purified tumor-reactive T cells. The cell products are oligoclonal, have an effector memory phenotype, and are of sufficient functional avidity to lyse T2 cells pulsed with low concentrations of NY-ESO-1 peptide, and tumor cell lines that express NY-ESO-1.
We were able to obtain regulatory approval from the FDA to use this methodology for the generation of clinical grade T cell products for the treatment of patients with advanced cancer. The selection reagents for cell sorting, peptide-MHC tetramer complexes conjugated to a fluorescence molecule, were tested for sterility, endotoxin and mycoplasma prior to GMP use in order to assure safety in these reagents in a GMP environment. While MHC streptamers (produced by IBA) offer the advantage of reversible binding to the target cell ,, there was no apparent impact on the ability to expand these cells after sorting and given the small amount of tetramer reagent used and the multiple washes occurring during the two expansions, any remaining tetramer present in the final product is unlikely to be clinically relevant and was not a concern for regulatory approval.
Other investigators have used retroviral and lentiviral vectors to insert an NY-ESO-1 specific TCR into T cells and redirect their specificity to tumor cells ,. Genetic modification has the advantage of using an off the shelf reagent to engineer each patient's T cells with an identical high affinity TCR. However, there are theoretical safety concerns related to the potential for cross pairing of the introduced TCR chains with endogenous chains to confer autologous reactivity  and the use of affinity-enhanced and xenogeneic TCR has also raised serious safety concerns related to recent patient deaths ,. Practical considerations of genetically modifying cells for altered specificity such as the cost and regulatory burden are also significant issues for many labs. The ETC (endogenous T cell therapy) approach presented here, obviates many of these issues and can provide T cell products that have comparable avidity and function to those generated by transfer of genes that encode a high affinity NY-ESO-1 specific TCR.
For this study, IL-21 was used to enrich for a population of CD8+ T cells with a central memory phenotype  which in our previous studies has demonstrated long-term in vivo persistence . Our decision to set a target cell dose of 1010 cells/m2 was based on prior studies where this dose range has been effective and allows for in vivo tracking of transferred T cells ,,. In light of the high replicative potential of IL-21 –primed CTL, a lower optimal cell dose may yet be determined; a lower dose requirement would allow for the collection of lower blood volumes and increase the feasibility of generating T cells to multiple targets from a single collection.
It is interesting to speculate on why the two final products tested by deep sequence were both over 85% comprised of a dominant clone and all products consisted of 15 or fewer clones. It may be that T cells specific for NY-ESO-1 are infrequently found in the natural repertoire. It is also likely that certain clones become dominant during the expansions following selection by cell sorting.
This was a small series limited to HLA A*0201 positive patients with NY-ESO-1 expressing sarcomas, accompanied by some variability among the NY-ESO-1 specific T cell products with regards to their lytic ability and expression of markers of T cell differentiation. However, clinical cell sorting with HLA tetramers offers a platform that can be easily adapted to additional MHC restricted targets (for example other CT antigens such as PRAME and MAGE family antigens), and additional HLA alleles. Moreover this approach may be used with other reagents for detecting tumor-reactive T cells such as CD137, where knowledge of the HLA restricting allele and tumor antigen is not necessary . Antigen-specific CD4 T cells have also been shown to be effective for the treatment of patients with solid tumor malignancies and, with further development of the Class II tetramers, it will be possible to rapidly isolate such T cells in future trials ,,.
In summary, the results of this study demonstrate that rare tumor-reactive antigen-specific T cells can be successfully isolated from the peripheral blood of patients and expanded to numbers sufficient for adoptive therapy. By the use of in vitro stimulation as a means to augment the population of antigen-specific CTL in culture and enrich for a pool of CD28hi helper-independent CD8+ T cells following exposure to IL-21, together with tetramer-guided cell sorting under clinical manufacturing conditions, it is feasible to generate tumor-reactive antigen-specific CTL of sufficient magnitude (>30 billion) for therapy in 5-6 weeks from PBMC collection to T cell product. Strategies to further streamline this approach and validate the routine generation of T cells against additional target antigens such as WT-1, and additional CT family antigens that are expressed broadly in solid tumors, will facilitate entry of adoptive therapy into mainstream clinical practice and consideration as a possible treatment modality in patients with solid tumor malignancies.
NY-ESO-1 specific T cells can be isolated and expanded from the peripheral blood of patients with NY-ESO-1 expressing cancers under clinical manufacturing conditions for use in adoptive T cell therapy trials.
Patients, sample acquisition and initial processing
Patients were enrolled on protocols approved by the Fred Hutchinson Cancer Research Center (FHCRC) IRB for tissue and blood procurement between September 2011 and May 2012, and provided informed consent in accordance with the Helsinki Declaration. HLA typing of patient samples was performed at the Puget Sound Blood Center (PSBC). Patients that expressed HLA A*0201, had an ECOG performance status of 1 and tumor biopsies with positive staining for NY-ESO-1 in >25% of cells by immunohistochemistry underwent leukapheresis at either the PSBC or University of Washington General Clinical Research Center. All further processing of the leukapheresis product was performed at FHCRC in the Cell Professing Facility (CPF) under current Good Manufacturing Practice (cGMP) guidelines. A portion of the leukapheresis product (2 × 109 cells) was CD25 depleted on a CliniMACS system using clinical grade CD25 MicroBeads [Miltenyi Biotec, Auburn, CA, USA] to remove CD4+ regulatory cells. Both the CD25-depleted mononuclear cell fraction, as well as the remaining unprocessed peripheral blood mononuclear cells (PBMC), were cryopreserved; the latter being used for dendritic cell (DC) generation.
Culture of dendritic cells
The protocols for DC generation have been described previously . Briefly, PBMC were suspended in AIM-V medium at 3 × 10^6 cells/mL, and then placed in sterile tissue culture dishes at 3 mL/well to separate plastic adherent and non-adherent populations by culture for 1 hour at 37°C. Adherent cells were treated with GM-CSF (800 U/mL) [MP Biomedicals, Santa Ana, CA, USA] and IL-4 (500 U/mL) [R&D Systems, Minneapolis, MN, USA] for 6 days to promote DC differentiation, and the DC were then matured for 2 days using a cytokine cocktail containing TNF-α (10 ng/mL), IL-1β (2 ng/mL), IL-6 (1000 U/mL), PGE-2 (1000 ng/mL) [all from R&D Systems, Minneapolis, MN, USA], IL-4 (500 U/mL) and GM-CSF (800 U/mL). Mature DC's were generally used fresh (without freezing or thawing) for the initial stimulation but excess DC's were frozen and frequently used in the second stimulation.
Stimulation of NY-ESO-1 specific T cells
DC's were pulsed for 2 hours with 10-40 μg/mL of the NY-ESO-1157-165 peptide in PBS with 1% HSA, washed, irradiated (5000 rads), and then co-cultured in 48 well plates with CD25 depleted PBMC in RPMI, 25 mM HEPES, 2 mM L-glutamine, 10% human AB serum (CTL medium) and β2-microglobulin (3 μg/mL) [Scripps Laboratories, San Diego, CA, USA]. Each plate was seeded with 70 × 106 CD25 depleted PBMC and 1.8 to 5 × 106 DC's divided equally among the 48 wells. Two stimulations with peptide pulsed DC were performed 7 days apart. During the first stimulation, IL-21 (30 ng/mL) [Peprotech, Rocky Hill, NJ, USA] was added twice in the first 4 days, and during the second stimulation cycle, IL-21 (30 ng/mL) is added on the first day and IL-2 (10 ng/mL) [Bayer, Terrytown, NY, USA] and IL-7 (5 ng/mL) [R&D Systems, Minneapolis, MN, USA] were added on the first day and days two through four . Stimulations for gp100 specific and MART1-specific T cells were performed using the same protocol using gp100154-162 or MART127-35 peptides, respectively.
Sorting and expansion
After two stimulations, an aliquot of each well was stained with an HLA A*0201 MHC tetramer folded with the NY-ESO-1157-165 peptide produced in the Immunologic Monitoring Core Facility at FHCRC. Wells that contained >0.5% tetramer positive cells were pooled, sorted using only forward, side scatter and single color tetramer parameters on a clinically qualified INFLUX cell sorter [Becton Dickenson, Franklin Lakes, NJ, USA] located within the CPF, and expanded using a rapid expansion protocol (REP) in a sterile 25 mL flask using an IL-2 concentration of 50U/mL as previously described . In some cases, wells with <0.5% tetramer positive cells were sorted and expanded if there was clearly a distinct tetramer positive population. After expansion, a sample of the T cells were again stained with anti-CD8 mAb and NY-ESO-1157-165 tetramer to determine the degree of enrichment of tetramer positive (tet+) cells, and tested in a chromium release assay for lysis of T2 lymphocytes pulsed with NY-ESO-1157-165 peptide. A final large volume expansion was performed using either bags [Lifecell, Branchburg, NJ, USA] or GREX flasks [Wilson-Wolf, St. Paul, MN, USA].
To facilitate detailed functional analysis, an aliquot of some T cell products was removed from the CPF after the first expansion, and expanded in the research lab for in vitro assays to assess recognition of target cells pulsed with various concentrations of peptide and to assess cytokine production in response to antigen stimulation. Cell surface phenotype and TCR Vβ spectratyping were performed on aliquots from the second expansion.
Phenotyping and functional analysis of NY-ESO-1-specific T cells
Cell surface phenotype was determined by co-staining with NY-ESO-1 tetramer (APC) and the following fluorochrome conjugated antibodies: CD8 (BV421) [BD Bioscience, Franklin Lakes, NJ, USA], CD28 (PE- Texas Red) [Beckman Coulter, Brea Ca, USA], CD27 (BV711), CCR7 (PE-Cy7), CD127 (PE) [all BD Pharmigen, San Diego, CA, USA], CD62L (APC-eFluor780) [Biolegend, San Diego, CA, USA], and CD45RO (FITC) [Invitrogen, Grand Island, NY]. Cells were analyzed on an LSRII [Becton Dickinson, Franklin Lakes, NJ, USA] using FlowJo software.
The NY-ESO-1 specificity of the expanded T cell products was confirmed using chromium release assay performed on day 12 of the REP. T2 lymphocytes cultured alone for 2 hours or in media with the NY-ESO-1157-165 peptide and HLA A*0201 positive, NY-ESO-1 positive tumor line Mel A375 (A375) were used as target cells.
In order to test NY-ESO-1 specific CTL lines in sarcoma tumor lines, the SS cell line SYO-1 (gift of Dr. Akira Kawai ) and the MRCL cell line 402 (gift of Pierre Aman  ) were used. Because neither of these cell lines are positive for HLA A*0201, they were transfected with the lentivirus pRRLSIN with A*0201 cloned into it. To further purify the A*0201 expressing population, tumor cells were stained using an antibody for A02 (PE) [BD Pharmigen, San Diego, CA, USA] then sorted using a FACSAria cell sorter (Becton Dickson) to isolate A02 expressing tumor cells. Cell were then grown in culture and confirmed to express A02 by flow cytometry prior to chromium release assay.
Target cells were labeled with 100 μCi 51Cr in 1 mL of media and co-cultured with effector T cells for 4-6 hours at 37°C plus 5% CO2 at a 20:1 effector to target (E:T) ratio unless otherwise specified. Chromium release experiments were performed in sextuplicate and to remove outliers in a consistent fashion, the highest and lowest values for each target/effector ratio were discarded. As a positive control, we tested an NY-ESO-1-specific T cell clone generated in our lab , and T cells transduced with the αLY NY-ESO-1 specific TCR  (gift of Paul Robbins courtesy of Dr. E.H. Warren).
For cytokine analysis, T cells were incubated overnight at a 20:1 E:T ratio (200,000 effectors with 10,000 targets) in 200 μL CTL media with T2 lymphocytes alone or with T2 lymphocytes pulsed with NY-ESO-1157-165 peptide (10 μg/mL) for 2 hours and then washed before plating in the assay. Supernatant was analyzed for using a luminex assay for IFN-gamma (Fisher) and TNF alpha [R&D Systems, Minneapolis, MN, USA].
Immunohistochemical staining for all SS and MRCL patients was performed at the University of Washington Pathology lab with mAb specific for NY-ESO-1 (1:100, E978 clone, Life Technologies, Grand Island, NY) using an automated immunostainer (Bond III). Testis was used as a positive control.
Spectratyping and deep sequencing of T cell receptors
TCR β-chain spectratype analysis was performed by the Immune Monitoring Laboratory at Fred Hutchinson Cancer Research Center according to the protocol developed by Akatsuka et al.  Briefly, cDNA was generated from 1-5 × 106 cells and five multiplex PCR reactions were run to amplify the CDR3 variable regions of each of the 23 TCR β-chain families. The PCR products were analyzed by capillary electrophoresis on the 3730 xl DNA analyzer and GeneMapper software [Life Technologies/Applied Biosystems, Van Allen Way, Ca, USA]. TCR Vβ sequencing and normalization was performed by Adaptive Biotechnologies [Seattle, WA, USA].
