MT3-KN035 Nanoparticles Based on PD-L1 Nanobodies Allow for Multiple Drug Conjugations that Promote Chemo- and Immunosynergistic Therapies. (PubMed, ACS Biomater Sci Eng) - "Meanwhile, MT3-KN035 conjugated multiple aldoxorubicin (hereafter, these conjugates are referred to as MT3-KN035-DOX) via an acidic cleavable linker; MT3-KN035-DOXHigh induced tumor apoptosis and exhibited significant antitumor efficacy via facilitating immune cell infiltrations. This work provides a novel therapeutic strategy via nanobody-mediated target engagement and internalization that achieves synergistic therapeutic efficacy between chemotherapy and immune checkpoint blockade therapy."

Tumor delivery and exposure of aldoxorubicin compared with doxorubicin: Integrated clinical and preclinical analysis. (ASCO 2026) - P2 | "Across integrated human and mouse datasets, aldoxorubicin achieved consistently higher tumor exposure than doxorubicin when normalized for dose, with potency-adjusted analyses supporting at least comparable active exposure. Together, these findings support aldoxorubicin as a tumor-targeted anthracycline capable of delivering greater active drug levels to tumors with improved tolerability, offering the potential for enhanced therapeutic index compared with doxorubicin."

Cardiac safety of aldoxorubicin compared to doxorubicin: Integrated results from two randomized studies in advanced soft tissue sarcoma. (ASCO 2026) - P2, P3 | " Cardiac safety data were analyzed from two randomized studies, INNO-206-STS-P2-01 (NCT01514188) and ALDOXORUBICIN-P3-STS-01 (NCT02049905), comparing aldoxorubicin with doxorubicin in advanced soft tissue sarcoma. Across two randomized studies, aldoxorubicin demonstrated a consistently more favorable cardiac safety profile than doxorubicin despite higher cumulative exposure, with smaller LVEF declines and fewer heart-failure–related events. These findings support aldoxorubicin as a potentially safer anthracycline option for patients requiring sustained exposure."

Albumin Nanoparticles as Multifunctional Carriers for Advanced Therapeutics. (PubMed, Pharmaceutics) - "The success of Abraxane as an effective treatment for metastatic breast cancer and non-small cell lung carcinoma, the application of Optison in ultrasound imaging, and the use of Nanocoll as an agent for SPECT diagnostics in sentinel node localisation confirm the strong potential of albumin-based systems. Further benefits are expected in patients with soft tissue cancers, as LadRx is seeking FDA marketing approval for Aldoxorubicin...It also briefly discusses methods of synthesis and surface modification of albumin nanocarriers to enable targeted delivery to pathological sites. Finally, it outlines the latest approaches in multimodal theranostic platforms, highlighting albumin's potential to improve cancer 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."

Physalis Mottle Virus-Like Nanocarriers with Expanded Internal Loading Capacity. (PubMed, Bioconjug Chem) - "Specifically, the A31C and S137C mutants show a greater than 10-fold increased rate of reactivity towards thiol-reactive small molecules, and PhMV Cys1 (A31C), PhMV Cys2 (S137C), and PhMV Cys1+2 (double mutant) VLPs display up to three-fold increased internal loading of the small molecule chemotherapeutics aldoxorubicin and vcMMAE and up to four-fold increased internal loading of the MRI imaging reagent DOTA(Gd). These results further improve upon a promising plant virus-based nanocarrier system for use in targeted delivery of small-molecule drugs and imaging reagents in vivo."
