Impact of the IL-15 superagonist N-803 on lymphatic reservoirs of HIV. (PubMed, JCI Insight) - "Our findings suggest N-803 may reduce the HIV reservoir in LTs of PWH on ART, an effect likely mediated by enhanced NK cell function. Controlled studies assessing the impact of NK cell therapy on HIV LTs are needed."

ABLE-22: Safety and efficacy evaluation of nadofaragene firadenovec alone or in combination with chemotherapy or immunotherapy—A randomized, open-label, phase 2 study. (ASCO 2025) - P3 | "Bladder-preserving treatment options for patients with BCG-unresponsive NMIBC with CIS ± Ta/T1 include intravesical gene therapy (nadofaragene firadenovec-vncg), intravesical chemotherapy (gemcitabine and docetaxel), and immunotherapy (intravenous pembrolizumab and intravesical nogapendekin alfa inbakicept-pmln). Exploratory endpoints include changes in expression of potential biomarkers in blood and urine. Results from this investigational, randomized, multicenter, open-label study evaluating the safety and efficacy of nadofaragene firadenovec alone or in combination with chemotherapy or immunotherapy are expected July 2028."

A phase II prospective, open-label, multi-center, single-arm study of sasanlimab plus sacituzumab govitecan in BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) pts: SSANTROP (APRO07-2022). (ASCO 2025) - "Pembrolizumab (Pem) was approved by the FDA based on Keynote-057 (41% complete response rate (CRR)) and offers a non-surgical option for pts who decline or are ineligible for RC. Nadofaregene firadenovec and Nogapendekin alfa inbakicept have been recently approved in this setting... This trial is the first to evaluate the combination of Sa and SG in BCG-unresponsive HR-NMIBC. With preliminary 3 mo CRR of 68%, the safety analysis identified no unexpected concerns, with severe AEs mainly involving neutropenia and febrile neutropenia. No treatment related toxic deaths occurred."

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."
