Combinatorial immunotherapy of anti-MCAM CAR-modified expanded natural killer cells and NKTR-255 against neuroblastoma. (PubMed, Mol Ther Oncol)
NKTR-255, a polymer-conjugated recombinant human interleukin-15 agonist, significantly stimulated NK cell proliferation and expansion and further enhanced the in vitro cytotoxic activity and in vivo anti-tumor efficacy of anti-MCAM-CAR-NK cells against NB. Our preclinical studies demonstrate that ex vivo expanded and modified anti-MCAM-CAR-NK cells alone and/or in combination with NKTR-255 are promising novel alternative therapeutic approaches to targeting MCAMhigh malignant NB.

A Phase 1 Clinical Trial of NKTR-255 with CD19-22 CAR-T Cell Therapy for Refractory B-cell Acute Lymphoblastic Leukemia. (PubMed, Blood)
The increase in chemokines was associated with decreases in absolute lymphocyte counts and CD8+ CAR T-cells in blood and ten-fold increases in CSF CAR-T cells, suggesting lymphocyte trafficking to tissue. Combining NKTR-255 with CAR19-22 was safe, feasible and associated with high rates of durable responses (NCT03233854).

Optimizing Ex-Vivo Expanded NK Cell- Mediated Cellular Cytotoxicity By Obinutuzumab Combined with NKTR-255 in Burkitt Lymphoma (BL) (ASH 2023)
NKTR-255 is an IL-15 receptor agonist designed to activate the IL-15 pathway and NK cells and promote the survival and expansion of memory CD8+ T cells without inducing suppressive regulatory T cells (Kuo/Zalevsky, Cancer Res. We found that NKTR-255 significantly enhanced the ADCC of expanded NK cells with Obinutuzumab against rituximab-resistant BL cells in vitro with enhanced IFN- g, granzyme B and perforin release. The in vivo effects of NKTR-255 with expanded NK cells and Obinutuzumab against rituximab-resistant BL cells using humanized NSG models are very promising. Mechanisms studies of BL relapsed from the combination therapy are under investigation.

NKTR-255, a polymer-conjugated IL-15, dramatically improves ROR1 CAR-T cell persistence and anti-tumor efficacy in an autochthonous model of ROR1+ lung cancer (AACR 2023)
Together, our work shows that NKTR-255 dramatically improves the persistence, function, and anti-tumor activity of ROR1 CAR-T cells in an aggressive autochthonous model of ROR1+ lung cancer. Our findings provide rationale to combine NKTR-255 with CAR-T cell therapy as a strategy to enhance the anti-tumor efficacy of CAR-T cells in patients with solid tumors.

Early Results of a Phase I Study of CAR-T Cells + NKTR-255 (PEG-IL-15) in Adults with R/R ALL (TCT-ASTCT-CIBMTR 2023)
Following lymphodepletion with fludarabine and cyclophosphamide, patients received the recommended Phase 2 dose of 3.0 x 10 6 /kg CAR-T cells (Spiegel, Patel, Muffly et al, Nature Medicine 2021). NKTR-255 administered at 1.5mcg/kg following CAR-T cell therapy was safe and appeared to promote CAR expansion in CNS and peripheral blood. Dose escalation is ongoing; additional safety data and longitudinal correlative assessments, including qPCR and cytokine data, will be presented at the meeting.

A Phase Ib Open-Label Study Evaluating the Safety and Efficacy of NKTR-255 in Combination with CD19-Directed CAR-T Cell Therapy in Patients with Relapsed/Refractory (R/R) Large B-Cell Lymphoma (LBCL) (ASH 2022)
Subjects will receive lymphodepletion chemotherapy with cyclophosphamide and fludarabine followed by liso-cel infusion per Breyanzi® package insert, and NKTR-255 at 1.5 µg/kg intravenously every 3 weeks starting at approximately 10 to 14 days after CAR-T cell infusion. Conclusion s : This clinical trial will evaluate the safety and efficacy of NKTR-255 in combination with liso-cel aiming to increase the response rates and durability of response compared with CD19 CAR-T cells alone. Based on the biological rationale of IL-15 supplementation, correlative data from CD19 CAR-T cell studies, and results from preclinical studies with xenogeneic mouse models, NKTR-255 has the potential to augment currently approved cellular therapies.

Safety, Tolerability, PK/PD and Preliminary Efficacy of NKTR-255, a Novel IL-15 Receptor Agonist, in Patients with Relapsed/Refractory Hematologic Malignancies (ASH 2022)
In preclinical studies, NKTR-255 enhanced antibody-dependent cellular cytotoxicity (ADCC) of daratumumab, rituximab, and cetuximab, resulting in synergistic antitumor effect. This ongoing Phase 1 trial (NCT04136756) evaluates safety, tolerability, pharmacokinetics (PK) and PD of NKTR-255 monotherapy and with subcutaneous (SC) Darzalex-Faspro (dara) or rituximab in patients with hematologic malignancies... In heavily pretreated patients with heme malignancies NKTR-255, alone and with SC dara was well-tolerated, manageable and biologically active with sustained increases in NK and CD8+ T cells. NKTR-255 administration replenished dara-induced NK cell depletion. Optimal biological response of NKTR-255 monotherapy was observed between 6-9 µg/kg and will be further tested in Phase 2.

Safety, Tolerability, PK/PD and Preliminary Efficacy of NKTR-255, a Novel IL-15 Receptor Agonist, in Patients with Relapsed/Refractory Hematologic Malignancies (ASH 2021)
In preclinical studies, NKTR-255 enhanced antibody-dependent cellular cytotoxicity (ADCC) of each of daratumumab, rituximab, trastuzumab, and cetuximab, resulting in synergistic anticancer activity. In this heavily pretreated relapsed/refractory patient population with hematologic malignancies, NKTR-255 was biologically active, and demonstrated sustained increases in NK and CD8 + T cells. NKTR-255 was well tolerated with minimal treatment-related toxicities and transient upregulation and rapid decline of cytokines to baseline levels. RP2D for NKTR-255 monotherapy has not yet been reached; and dose escalation is ongoing at 9.0 µg/kg.

Pharmacodynamic Analysis of CAR-T Cell Persistence in Patients with Hematologic Malignancies Treated with NKTR-255, an IL-15 Receptor Agonist That Enhances CD8+ T-Cells: Preliminary Results from a Phase 1 Study (ASH 2021)
Following treatment with NKTR-255, there was an increase in CAR-T-cells as well as a reversal of the CD4 + :CD8 + ratio in 1 patient. Additionally, NKTR-255 induced expansion of total CD8 + cell fraction with an increase of proliferation index of Ki67 in all reported patients, supporting its role in enhancing the expansion and proliferative ability of cytotoxic T cells. Low baseline CAR-T/CAR-NK cell counts observed in patients may be due to longer time intervals between CAR-T infusion and the first dose of NKTR-255.
