Delivery Strategy·Research·Since 2026

Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

We then focus on bottlenecks such as target selection strategies, engineering design, and TME-driven issues like phenotypic inactivation and antigen escape, discussing corresponding optimization approaches like armoring modifications, logic-gated designs, and convection-enhanced delivery.

Published Workflows

Objective: Translate CAR-M therapy for glioblastoma from preclinical concept toward early-phase clinical testing while prioritizing mechanistic validation.

Why it works: The proposed pathway is expected to work by using biomarker-supported mechanistic validation in early-phase clinical trials to answer fundamental questions about CAR-M homing, survival, and function in patients before broader efficacy claims are made.

Stages

  1. 1.
    Mechanistic validation in early-phase clinical trials(confirmatory_validation)

    The stage exists because the review identifies a translational gap and states that clinical efficacy in GBM remains unproven, so mechanistic questions in patients should be prioritized.

    Selection: Use biomarker-supported early-phase clinical testing to answer fundamental biological questions about CAR-M homing, survival, and function in patients.

Implementation Constraints

The abstract only supports that it is a delivery strategy considered during CAR-M optimization for GBM. Specific hardware or procedural requirements are not described in the provided text.; used in the context of GBM-directed CAR-M translation

The abstract does not claim that convection-enhanced delivery alone resolves phenotypic inactivation, antigen escape, or the overall lack of proven clinical efficacy.

Claim 3therapeutic rationalesupports2026Source 1needs review

CAR-M therapy is presented as a promising therapeutic avenue for glioblastoma because of tumor-homing capacity, tumor microenvironment reprogramming, and the potential to bridge innate and adaptive immunity.

Chimeric antigen receptor macrophages (CAR-M) therapy presents a promising new avenue for GBM treatment, leveraging its inherent tumor-homing capacity, TME reprogramming function, and potential to bridge innate and adaptive immunity.

Compared with intranasal oxytocin

convection-enhanced delivery and intranasal oxytocin address a similar problem space because they share translation.

Shared frame: same top-level item type; shared target processes: translation; shared mechanisms: translation_control

Compared with lipid nanoparticles

convection-enhanced delivery and lipid nanoparticles address a similar problem space because they share selection, translation.

Shared frame: same top-level item type; shared target processes: selection, translation; shared mechanisms: translation_control
