Autologous human preclinical modeling of melanoma interpatient clinical responses to immunotherapeutics. (PubMed, J Immunother Cancer)
Our model reproduces differential effects of immunotherapy in melanoma patients, capturing the inherent heterogeneity in clinical responses. Taken together, these data demonstrate our model's translatability for novel immunotherapies in melanoma patients. The data are also supportive for the continued clinical investigation of nemvaleukin as a novel immunotherapeutic for the treatment of melanoma.

Rethinking Oncologic Treatment Strategies with Interleukin-2. (PubMed, Cells)
High-dose recombinant human IL-2 (rhIL-2, aldesleukin) emerged as an important treatment option for selected patients with metastatic melanoma and metastatic renal cell carcinoma, producing durable and long-lasting antitumor responses in a small fraction of patients and heralding the potential of cancer immunotherapy...In this review, we highlight novel drug development strategies, including biochemical modifications and engineered IL-2 variants, to expand the narrow therapeutic window of IL-2 by leveraging downstream activation of the IL-2 receptor to selectively expand anti-tumor CD8-positive T cells and natural killer cells. These modified IL-2 cytokines improve single-agent activity in solid tumor malignancies beyond the established United States Food and Drug Administration (FDA) indications of metastatic melanoma and renal cell carcinoma, and may also be safer in rational combinations with established treatment modalities, including anti-PD-(L)1 and anti-CTLA-4 immunotherapy, chemotherapies, and targeted therapy approaches.

A novel murine tumor model for assessing the efficacy of neoadjuvant dosing regimens for immunotherapies (AACR 2023)
MC38 tumor-bearing C57Bl/6 mice were subcutaneously administered murine nemvaleukin alfa (mNemva), an engineered IL-2 immunotherapy that selectively activates and expands cytotoxic NK cells and antigen-experienced CD8+ T cells. Moreover, long-term immunity was 100% effective if the re-challenge experiment was performed out to 5 months after the last dose of mNemva had been administered.Therefore, the neoadjuvant/adjuvant dosing regimen exhibits a superior response in this preclinical model, when combined with partial tumor-debulking surgery, similar to the recent findings in patients with melanoma that were treated with pembrolizumab. In addition, this strategy enables sampling of tumor tissue for analyses of the immune response and the identification of potential predictive markers of response.

Developing an autologous humanized mouse model to assess responses to novel immunotherapeutics (AACR 2023)
In this all autologous humanized melanoma mouse model, nemvaleukin treatment not only enhances T cell engraftment, it significantly augments anti-tumor efficacy. These data support the use of this personalized melanoma xenograft model to analyze the underlying immune responses in responders and non-responders to novel immunotherapies.

Nemvaleukin alfa, a novel engineered IL-2 fusion protein, drives antitumor immunity and inhibits tumor growth in small cell lung cancer. (PubMed, J Immunother Cancer)
mNemvaleukin, a novel cytokine-based immunotherapy, significantly inhibited murine SCLC tumor growth and prolonged survival, which was further enhanced by the addition of chemotherapy. mNemvaleukin alone, and in combination with chemotherapy, drove a strong antitumor immune program elicited by cytotoxic immune cells. Our findings support the evaluation of nemvaleukin alone or in combination with chemotherapy in clinical trials for the treatment of SCLC.

Potential IL2 Substitute Shrinks Solid Tumors. (PubMed, Cancer Discov)
Nemvaleukin alfa, an engineered cytokine that may induce the tumor-fighting benefits of IL2 without the side effects, has demonstrated effectiveness against solid tumors. As a monotherapy, the drug produced overall response rates of 13% in patients with advanced melanoma and 18.2% in advanced renal cell carcinoma. When combined with pembrolizumab, the drug produced responses in 16.1% of patients with various solid tumor types.

[VIRTUAL] Antitumor efficacy and immune profiling of the mouse ortholog of nemvaleukin alfa, a novel engineered IL-2 fusion protein, in an orthotopic mouse model of small cell lung cancer alone or in combination with standard chemotherapy (ESMO 2021)
After confirming tumor burden by magnetic resonance imaging (MRI), mice were treated with RDB 1462 alone or in combination with standard chemotherapy (cisplatin + etoposide). The mouse version of nemvaleukin, RDB 1462, demonstrated anti-tumor immunity in a murine model of SCLC. RDB 1462 reduced SCLC growth and prolonged survival in mice, which was further enhanced by combining with standard chemotherapy. The data could potentially support further evaluation of nemvaleukin in the treatment of SCLC either alone or in combination in the clinic.

[VIRTUAL] Nemvaleukin alfa monotherapy in patients with advanced melanoma: ARTISTRY-1 (EADO-WCM 2021)
Both patients had received prior nivolumab adjuvant therapy and had relapsed 8-9 months after completing nivolumab therapy. Nemvaleukin is a novel, investigational agent that is generally well tolerated, has demonstrated antitumor activity, and can be administered in an outpatient setting. Single-agent activity was observed among patients with melanoma who were previously treated with a CPI. Response criteria were met to expand the monotherapy melanoma cohort, and research of nemvaleukin among patients with advanced melanoma is ongoing.

[VIRTUAL] The combination of a mouse ortholog of ALKS 4230, a selective agonist of the intermediate affinity IL-2 receptor, and the angiogenesis inhibitor lucitanib enhances antitumor activity (AACR-II 2020)
ALKS 4230, an engineered cytokine designed for selective binding to the intermediate affinity interleukin-2 receptor (IL-2R), is being evaluated as a monotherapy and in combination with pembrolizumab in patients with advanced solid tumors. The combination led to a significant (p<0.05) increase in intratumoral CD8+ T cells and dendritic cells (CD11c+F4/80-), together with a reduction in tumor-associated macrophages (CD11b+F4/80+). The combination treatment elicited a distinct gene expression profile in tumors by RNA-Seq, merging the immunostimulatory effects of RDB 1462 with the anti-angiogenic effects of lucitanib.The combination of an intermediate affinity IL-2R-selective cytokine and an angiogenesis inhibitor resulted in durable dose-dependent antitumor efficacy in the MC38 mouse tumor model.

ALKS 4230: a novel engineered IL-2 fusion protein with an improved cellular selectivity profile for cancer immunotherapy. (PubMed, J Immunother Cancer)
ALKS 4230 exhibited enhanced pharmacokinetic and selective pharmacodynamic properties resulting in both improved antitumor efficacy and lower indices of toxicity relative to rhIL-2 in mice. These data highlight the potential of ALKS 4230 as a novel cancer immunotherapy, and as such, the molecule is being evaluated clinically.
