Abstract

Therapies to reduce liver fibrosis and stimulate organ regeneration are urgently needed. We conducted a first-in-human, phase 1 dose-escalation trial of autologous macrophage therapy in nine adults with cirrhosis and a Model for End-Stage Liver Disease (MELD) score of 10-16 (ISRCTN 10368050). Groups of three participants received a single peripheral infusion of 10 7, 10 8 or up to 10 9 cells. Leukapheresis and macrophage infusion were well tolerated with no transfusion reactions, dose-limiting toxicities or macrophage activation syndrome. All participants were alive and transplant-free at one year, with only one clinical event recorded, the occurrence of minimal ascites. The primary outcomes of safety and feasibility were met. This study informs and provides a rationale for efficacy studies in cirrhosis and other fibrotic diseases.

  • During 12 months of follow-up after autologous macrophage transplantation, 70 adverse events were documented, 44% were considered related to transplantation, and none had a CTCAE severity grading over 2.

    “During 12 months of follow-up, 70 AEs were documented, with 44% considered related to the transplantation, but none of these AEs had a Common Terminology Criteria for Adverse Events (CTCAE) severity grading over 2.”

    From Mechanisms, efficacy, and future perspectives of cellular-based therapies for liver fibrosis/cirrhosis: focusing on mesenchymal stromal cells (2025) · cites this paper as [22]

    The Safety outcomes section reports 70 adverse events during one year of follow-up and says 56% were unrelated to the investigational product, supporting the cited 44% related figure. The Discussion limits the CTCAE grade ≤2 finding to events possibly related to the product; it does not establish that none of all 70 events exceeded grade 2. Page numbers are unavailable in our copy. (LLM, conf=0.86)

  • In patients with liver cirrhosis, up to 1×10^9 in vitro expanded autologous bone marrow-derived macrophages were administered through a peripheral vein.

    “in vitro expanded autologous BMDMs respectively through a peripheral vein [22].”

    The Introduction and Method of cell production describe autologous macrophages made by culturing monocytes collected from patients’ blood by leukapheresis, then infused peripherally in patients with cirrhosis. The Discussion reports a maximum-achieved dose of 0.8×10^9 cells. The paper does not describe the administered cells as bone marrow-derived macrophages or establish that they were expanded in culture rather than differentiated there. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Recent clinical trials provided evidence that administration of autologous macrophage therapy for liver fibrosis is safe, although the nature of these trials precluded efficacy assessment.

    “recent clinical trials have provided evidence that the administration of autologous macrophage therapy for liver fibrosis is safe, although the nature of these trials precluded efficacy assessment (52, 53).”
  • Phase I studies demonstrated that macrophage infusion was safe and well-tolerated, and showed improvement in some serum biomarkers after treatment (C3M, PRO-C3, and ELF).

    “Phase I studies demonstrated that macrophage infusion was safe and well-tolerated, and even showed improvement in some serum biomarkers after treatment (C3M, PRO-C3, and ELF) (176).”

    From Targeting macrophages in liver fibrosis (2026) · cites this paper as [176]

  • A reduction of MELD scores was observed in six of nine patients 90 days following macrophage infusion, and in seven of nine patients one year post-infusion.

    “A reduction of MELD scores was observed in six of the nine patients 90 days following macrophage infusion, and in seven of the nine patients one year post-infusion.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
