Abstract
BACKGROUND Even acknowledging the game-changing results achieved in the treatment of metastatic melanoma with the use of immune checkpoint inhibitors (ICI), a large proportion of patients (40-60%) still fail to respond or relapse due to the development of resistance. Alterations in the expression of Human Leukocyte Antigen class I (HLA-I) molecules are considered to play a major role in clinical resistance to ICI. Cellular immunotherapy with HLA-independent CAR-redirected lymphocytes is a promising alternative in this challenging setting and dedicated translational models are needed. METHODS In this study, we propose an HLA-independent therapeutic strategy with Cytokine Induced Killer lymphocytes (CIK) genetically engineered with a Chimeric Antigen Receptor (CAR) targeting the tumor antigen CSPG4 as effector mechanism. We investigated the preclinical antitumor activity of CSPG4-CAR.CIK in vitro and in a xenograft murine model focusing on patient-derived melanoma cell lines (Mel) with defective expression of HLA-I molecules. RESULTS We successfully generated CSPG4-CAR.CIK from patients with metastatic melanoma and reported their intense activity in vitro against a panel of CSPG4-expressing patient-derived Mel. The melanoma killing activity was intense, even at very low effector to target ratios, and not influenced by the expression level (high, low, defective) of HLA-I molecules on target cells. Furthermore, CAR.CIK conditioned medium was capable of upregulating the expression of HLA-I molecules on melanoma cells. A comparable immunomodulatory effect was replicated by treatment of Mel cells with exogenous IFN-γ and IFN-α. The antimelanoma activity of CSPG4-CAR.CIK was successfully confirmed in vivo, obtaining a significant tumor growth inhibition of an HLA-defective Mel xenograft in immunodeficient mice. CONCLUSIONS In this study we reported the intense preclinical activity of CSPG4-CAR.CIK against melanoma, including those with low or defective HLA-I expression. Our findings support CSPG4 as a valuable CAR target in melanoma and provide translational rationale for clinical studies exploring CAR-CIK cellular immunotherapies within the challenging setting of patients not responsive or relapsing to immune checkpoint inhibitors.

Abstract
Abstract
Purpose of this study is to explore the preclinical efficacy of Chondroitin Sulfate Proteoglycan 4 (CSPG4)-specific CAR-engineered Cytokine-Induced Killer lymphocytes (CIK) to eradicate melanoma cells with defective HLA class I (HLA-I). The latter abnormality plays a major role in clinical resistance to Checkpoint Inhibitors (CI). CSPG4 was selected as the target because of its high expression on melanoma and its restricted distribution in normal tissues. Our approach is based on CAR.CIK redirected against CSPG4. CIK, ex vivo expanded T-NK lymphocytes endowed with intrinsic HLA-independent antitumor activity, were used as effectors.
Experimental procedure. CAR.CIK were generated by retroviral transduction of patient derived PBMC with a vector encoding a 2nd generation CSPG4-CAR with 4-1BB co-stimulation. Surface HLA-I expression was evaluated by flow cytometry on melanoma cell lines (Mel), derived by surgical biopsies. These cells also served as targets for CSPG4 CAR.CIK. The activity of CSPG4 CAR.CIK was analyzed in vitro and in immunodeficient mice grafted with a patient-derived HLA-defective melanoma. Mice were treated intravenously with 3x106 CAR.CIK (5 cells infusions in total).
Results. CAR.CIK were efficiently generated from 4 melanoma patients. Mean expression of CSPG4-CAR was 48±8%, the rate of ex vivo expansion (84 fold) and phenotypic characteristics (CD3+CD8+=71±13%, CD3+ CD56+=22.5±13%, NKG2D+= 68±32.3%) were comparable with unmodified controls. Membrane HLA-I molecules were detected in 23/24 Mel samples, with a variable membrane density per cell (median 21232, range 787-49871). Sample Mel17 did not express HLA-I because of a start lost mutation (p.Met1Ile) in β2microglobulin. CSPG4 was intensely expressed by all Mel (78±5%), with no correlation to HLA-I levels. CSPG4 CAR.CIK efficiently killed 10 Mel samples in vitro, including Mel17 (HLA-I negative) and 2 Mel with the lowest HLA-I density (Mel71, Mel72). Mean Mel-specific killing by CSPG4 CAR.CIK was significantly higher compared with unmodified CIK especially at low effector/target (E/T) ratios (85% vs 40% at E/T=1:1; 46% vs 9% at E/T=1:8, p<0.0001). In vivo, CSPG4 CAR.CIK caused a significant inhibition of the HLA-negative Mel17 tumor growth (p<0.0001) as compared to controls. Antitumor activity was confirmed by the reduction of tumor weight and metabolic activity (by fluorescent glucose uptake) measured on the residual explanted tumors. Antitumor response persisted up to 2 weeks after end of the treatment.
Conclusions. We reported the activity of CSPG4 CAR.CIK against melanoma, including those with low or defective HLA-I expression. CIK may provide a valid platform for CAR-based strategies against melanoma and solid tumors in general. Our data provide the rationale to implement clinical studies exploring the proposed strategy in melanoma patients not responding or relapsing after immunotherapy with CI.

Abstract
PURPOSE No effective therapy is available for unresectable soft-tissue sarcomas (STS). This unmet clinical need prompted us to test whether chondroitin sulfate proteoglycan 4 (CSPG4)-specific chimeric antigen receptor (CAR)-redirected cytokine-induced killer lymphocytes (CAR.CIK) are effective in eliminating tumor cells derived from multiple STS histotypes in vitro and in immunodeficient mice. EXPERIMENTAL DESIGN The experimental platform included patient-derived CAR.CIK and cell lines established from multiple STS histotypes. CAR.CIK were transduced with a retroviral vector encoding second-generation CSPG4-specific CAR (CSPG4-CAR) with 4-1BB costimulation. The functional activity of CSPG4-CAR.CIK was explored in vitro, in two- and three-dimensional STS cultures, and in three in vivo STS xenograft models. RESULTS CSPG4-CAR.CIK were efficiently generated from patients with STS. CSPG4 was highly expressed in multiple STS histotypes by in silico analysis and on all 16 STS cell lines tested by flow cytometry. CSPG4-CAR.CIK displayed superior in vitro cytolytic activity against multiple STS histotypes as compared with paired unmodified control CIK. CSPG4-CAR.CIK also showed strong antitumor activity against STS spheroids; this effect was associated with tumor recruitment, infiltration, and matrix penetration. CSPG4-CAR.CIK significantly delayed or reversed tumor growth in vivo in three STS xenograft models (leiomyosarcoma, undifferentiated pleomorphic sarcoma, and fibrosarcoma). Tumor growth inhibition persisted for up to 2 weeks following the last administration of CSPG4-CAR.CIK. CONCLUSIONS This study has shown that CSPG4-CAR.CIK effectively targets multiple STS histotypes in vitro and in immunodeficient mice. These results provide a strong rationale to translate the novel strategy we have developed into a clinical setting.

Abstract
Abstract
Purpose: The goals of this study are i) to analyze the expression of human leukocyte antigen class I (HLA-I) antigen processing machinery (APM) components in surgically removed melanoma tumors, ii) to assess their modulation by Interferons (IFNs) and iii) to determine their value as predictive biomarkers of the clinical response to immunotherapy with checkpoint inhibitors (CI).
Methods: The expression levels of HLA class I APM components [HLA-I (ABC) chains, beta(2)microglobulin (β2m), Calnexin, Calreticulin, ERp57, Tapasin, TAP1-2, LMP2, LMP7, LMP10] were evaluated by staining with mAbs and flow cytometry in melanoma cells isolated from surgical biopsies from 16 patients with advanced melanoma. In addition the modulation of these molecules by IFN-γ or IFN-α2 (IFNs) was evaluated.
Results: The frequency of cells expressing HLA-I/β2m was >90% in 15/16 Mel tumors. In 1 case extracellular HLA-I/β2m molecules were not detected. The expression levels of extracellular HLA class I APM molecules were quite heterogeneous. Based on Mean Fluorescence Intensity (MFI) of HLA-I/β2m, Mel segregated into 2 groups with high (MFI >200, n=8) and low (MFI<200, n=8) expression levels. In 11 cases (5 from the high and 6 from the low expression groups) we could explore the modulatory activity of IFNs. In vitro exposure to IFNs globally enhanced the expression levels of HLA-I/β2m, allowing the transition from the low to the highexpression group in 1 case. The distribution of expression defects in the intracellular APM components resulted intensely heterogeneous. Highly defective (<25%) expressions were detected notably for LMP2 (12/16), TAP1 (13/16), TAP2 (10/16) and Tapasin (14/16). In 10 cases we could explore the beneficial modulatory activity of IFNs on defective APM components. IFNs could restore the expression of LMP2 (4/10), TAP1 (6/10), and TAP2 (7/8), but not that of Tapasin. Seven patients were treated with CI (either anti-PD1 or anti-CTLA4). Four of them had clinical responses (PR or CR); in 3 of them Mel expressed high levels of HLA-I/β2m. Conversely, Mel from all 3 patients that did not respond to CI expressed low HLA-I/β2m levels which could not be upregulated by IFNs. Highly defective expression of APM components, not responsive to IFN restoration, was detected in all 3 Mel from non-responders.
Conclusions: We report a wide heterogeneous distribution of HLA-I/β2m expression levels and deficits of APM components in Melanoma, partially restorable by IFNs. Our data support the possibility that defects in HLA expression, not responsive to IFN restoration, may predict low responsiveness to CI. We provide rationale to incorporate the evaluation of HLA-I/β2m and APM in clinical immunotherapy studies with CI.
