aldoxorubicin (INNO-206) / LadRx, Xoma - LARVOL DELTA

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."
