ATR inhibitor tuvusertib induces immunogenic modulation and sensitizes prostate carcinoma to natural killer cell-mediated cytotoxicity which is further enhanced by the IL-15 superagonist N-803
(SITC 2025)
- "Impedance-based real-time cell analysis was used to assess the lysis of tuvusertib-treated PCa cells upon co-incubation with PBMC-derived NK cells in the presence or absence of anti-PD-L1 avelumab, PD-L1 targeting high-affinity NK cell line (PD-L1 t-hANK) cells, or TRAIL ligand. TRAIL signaling blockade mitigated the NK cell lysis of tuvusertib-treated cells. In vivo, tuvusertib and N-803 combination therapy resulted in the significant tumor growth control of the DU145 xenograft (p<0.0001) and the prolonged survival of the animals (p<0.05).Conclusions This study supports the combination of the ATR inhibitor tuvusertib with the anti-PD-L1 avelumab and/or IL-15 superagonist N-803 for prostate carcinoma.Acknowledgements This work was funded by the Intramural Research Program of the Center for Cancer Research, National Cancer Institute (NCI), National Institutes of Health and via Cooperative Research and Development Agreements (CRADAs) between the NCI and the..."

Association of lymphopenia rescue and CA19-9 levels with overall survival following IL-15 superagonist N-803 and PD-L1 t-haNK chemo-immunotherapy for 3rd line or greater metastatic pancreatic cancer.
(ASCO 2025)
- P2 | "The multimodal chemo-immunotherapy protocol to induce immunogenic cell death resulted in OS that exceeded 6 months for both 3rd and ≥ 5th line patients, exceeding OS achieved by other therapies in this setting by ~2 months. It is notable that both favorable baseline ALC/CA19-9 and on-study higher ALC was associated with prolonged survival, given N-803's ability to increase both NK and CD8+/CD4+ T cells, the first FDA approved agent that proliferates lymphocytes in the face of lymphopenia. These findings support further investigation of this novel therapeutic regimen that includes PD-L1 t-haNK, and N-803 that, as an IL-15 superagonist, may be able to overcome lymphopenia and improve prognosis."

Generation of cytokine-induced memory-like PD-L1 t-haNK (NK-92®) cells
(AACR 2025)
- "We show here that the Natural Killer cell line NK-92®, or 'activated' NK (aNKTM), can acquire a memory-like phenotype upon overnight induction with IL-12, IL-18, and the IL-15 superagonist N-803, as evidenced by increased steady-state IFNγ secretion (>50-fold increase) and up-regulation of CD25. This increase would then drive upregulation of PD-L1 expression on neighboring tumor cells, creating an expanding wave of targets sensitized to killing by PD-L1 t-haNK cells. A next generation, memory-like PD-L1 t-haNK cell line equipped with inducible safety switch features to remove the need for irradiation and extend their half-life in patients is being developed and would constitute a promising "off-the-shelf" cellular therapy against immunologically cold cancers."

Immunogenic modulation with the ATR inhibitor tuvusertib enhances NK-mediated killing of prostate cancer [WITHDRAWN]
(AACR 2025)
- "Furthermore, tuvusertib treatment increased PD-L1 expression on the DU145 cells, which is associated with enhanced donor NK killing in the presence of avelumab and augmented sensitivity to PD-L1 t-haNK cells.Next, the anti-tumor effect of combining tuvusertib with N-803 (provided by ImmunityBio, Culver City, CA, USA) was investigated. Furthermore, tuvusertib synergized with N-803, resulting in a superior anticancer response. This provides a rationale for further investigation of this combination therapy."

Case report: PD-L1-targeted high-affinity natural killer cells and IL-15 superagonist N-803-based therapy extend overall survival of advanced metastatic pancreatic cancer patients.
(PubMed, Front Oncol)
- "From late 2019 to 2021, single-patient Investigational New Drug (spIND) protocols for five mPC patients were designed and approved that generally comprised combined Abraxane (nab-paclitaxel) and gemcitabine therapy with experimental therapeutics N-803, PD-L1-targeted high-affinity natural killer (PD-L1 t-haNK) cells, and aldoxorubicin, a serum albumin-binding doxorubicin prodrug. Some patients also received stereotactic body radiation therapy (SBRT), cyclophosphamide, pembrolizumab, nivolumab, and/or experimental ETBX-051 (brachyury) and/or ETBX-061 (MUC1) vaccines...The OS of 13, 26.9, and 23.2 months for three patients is particularly notable. The findings here support the ongoing clinical investigations of N-803 and PD-L1 t-haNK cells in combination therapy."

Recurrent pancreatic cancer treated with N-803 and PD-L1 t-haNK followed by an EGFR-targeted nanocell drug conjugate.
(PubMed, Oncologist)
- "The epidermal growth factor receptor-targeted antibody-nanocell conjugate E-EDV-D682 provides tumor-targeted chemotherapy in the form of its anthracycline metabolite PNU159682 (nemorubicin) cargo and is currently being studied in combination with immunomodulatory EDVs delivering the adjuvant α-galactosyl ceramide (GC)...Under the initial single-patient Investigational New Drug (spIND) protocol, the patient received N-803, PD-L1 t-haNK cells, and the albumin doxorubicin conjugate aldoxorubicin for ~27 months...Due to progression, a second spIND protocol was designed whereby the patient received E-EDV-D682 plus EDV-GC for more than 24 months, which resulted in stable disease and the patient's continued survival at the time this report was written. The patient's extended survival despite the dire prognosis associated with recurrent mPC points to the merits of this temporal combination regimen in overcoming immuno-chemo resistance with enhanced immune activity..."
