In this study, we propose a Gas-Metal Synergy Strategy, which integrates immune activation and biosafety, by engineering a pH-responsive manganese-based zeolitic imidazolate framework (named MRPH) nanoplatform co-loaded with the nitric oxide (NO) donor RRX-001...Both in vitro and in vivo studies demonstrate that MRPH significantly enhances gas-amplified metalloimmunotherapy. This work pioneers a low-toxicity paradigm that integrates gas therapy and metal-based immunotherapy, offering a transformative approach to solid tumor immunotherapy.

Investigational agents targeting CD47, such as magrolimab, aim to induce phagocytosis of tumor cells by TAMs...Compared to relatively low CD47 expression in primary CRC tumors, CRC liver metastases had very high CD47 expression. Quantification of TAM signatures and CD47 expression represent key biomarkers to monitor in patient samples during exploration of CD47-blockade agents in the clinic.

CD47-targeted combinations demonstrate encouraging early phase efficacy and manageable safety in hematologic malignancies, with signals of benefit in higher-risk MDS, TP53-mutant AML, relapsed/refractory DLBCL, and rituximab-refractory iNHL. However, recent Phase III trials in newly diagnosed AML Daver et al. [27], and Zeidner et al. [26] did not confirm this benefit, underscoring that CD47 blockade remains investigational and requires validation in rigorously designed randomized studies.

Hu5F9-G4 demonstrates potential as a therapeutic agent in CRC by promoting M2d-to-M1 macrophage polarization, suppressing tumor progression, and influencing the autophagy pathway. These findings highlight CDKN1A and MAP1LC3B as promising targets for CRC therapy.

Introduction In this preclinical human immune system patient-derived xenograft (HIS PDX) model and phase II clinical trial, we assessed evorpacept (anti-CD47 engineered fusion protein with inactive Fc), cetuximab, and pembrolizumab (triple therapy) in microsatellite stable colorectal cancer (MSS CRC). Conclusions While triple therapy demonstrated evidence of efficacy in refractory MSS CRC, safety concerns halted enrollment. Further investigation is necessary to determine the optimal use of CD47-targeted therapies in MSS CRC.
