Aberrant Somatic Hypermutation Plays Minor Role in the Evolution of Molecular Alterations at Recurrence in PCNSL (AAN 2025) - "Samples analyzed using MSK-HemePACT panel...aSHM was observed in the archival tumor samples that were not shared with the CSF samples. Moreover, aSHM seemed to be a minor contributor to mutations identified in CSF samples. Possibly, aSHM does not play a role in PCNSL after initial diagnosis and therapy, accounting for sparsity of mutations caused by aSHM in recurrent/refractory CSF samples."

Developing a 3D bone model of osteosarcoma to investigate cancer mechanisms and evaluate treatments. (PubMed, FASEB J) - "Incubating bone cores with mifamurtide induced a reduction of cellular markers and an increase in bone volume. This 3D bone core model has the potential to investigate osteosarcoma tumor microenvironment and provides a representative model for evaluation of novel therapies."

SARCOMA DRUG APPROVALS IN LATIN AMERICA COMPARED TO THE FDA AND EMA: AN ANALYSIS BY THE LACOG SARCOMA GROUP (CTOS 2024) - "The FDA led the approvals, granting authorization to 18 of these treatments first, with Trabectedin being the sole exception, approved earlier by the EMA and COFEPRIS. Mifamurtide is the only new drug against sarcoma licensed by the EMA but not by the FDA... The observed discrepancies in drug approval timelines and the lower number of drug approvals in Latin American countries, as compared to those by the FDA and EMA, may exacerbate disparities in treatment accessibility for sarcoma patients in these regions. Approvals of sarcoma drugs by regulatory agencies of Latin American countries were more frequently conditioned to phase 3 trials and overall survival benefit."

Long-Circulating and Targeted Liposomes Co-loading Cisplatin and Mifamurtide: Formulation and Delivery in Osteosarcoma Cells. (PubMed, AAPS PharmSciTech) - "The constructed long-circulating targeted liposomes co-loading DDP and mifamurtide significantly inhibited the cell viability, migration, invasion and cell apoptosis of MG-63 cells, improving the antitumor effect of DDP and mifamurtide in vitro. The constructed liposomal delivery system is suitable for co-loading DDP and mifamurtide to achieve active tumor targeting, supplying a new strategy for the treatment of OS."

Cost-Effectiveness Analysis of Osteosarcoma Treatment: Insights From a Systemic Literature Review (ISPOR-EU 2024) - "The literature search identified only one intervention, mifamurtide, with economic evaluations in osteosarcoma and thus, indicating a significant unmet need. Mifamurtide in combination with chemotherapy was a cost-effective option compared to chemotherapy alone. Further research is essential to assess the economic impact of emerging therapies for this rare disease."

Chondrosarcoma Co-Culture 3D Model─An Insight to Evaluate Drugs Acting on TAMs. (PubMed, ACS Biomater Sci Eng) - "Finally, mifamurtide, an immunomodulator acting on TAMs, was evaluated on the most in vitro relevant model: 3D co-culture CH2879 model. Our results showed that it is now possible to develop 3D models that very accurately mimic what is found in vivo with the possibility of evaluating treatments specific to a tumor cell component."

ICONIC (IMPROVING OUTCOMES THROUGH COLLABORATION IN OSTEOSARCOMA): A PROSPECTIVE OBSERVATIONAL COHORT STUDY FOR NEWLY DIAGNOSED OSTEOSARCOMA PATIENTS IN THE UNITED KINGDOM (UK) (CTOS 2023) - P=N/A | "Multi-agent adjuvant chemotherapy treatment has been initiated in 133 patients, 99 (74%) of which included methotrexate and 50/78 (64%) of patients eligible to receive adjuvant mifamurtide following NICE recommendations have received at least 1 dose (median 27, range 1-49). ICONIC is the first prospective observational cohort study to recruit UK patients of all ages with newly diagnosed OS. Initial analyses have demonstrated the feasibility of comprehensive data and sample collection and identified differences in systemic management of patients across the country worthy of further investigation ICONIC provides a unique resource that will allow for better understanding of the biology of OS and aid development of new biomarkers and novel therapeutic approaches. Analyses are aligned with objectives within the newly formed European consortium, Fight Osteosarcoma Through European Research (FOSTER) where possible and provide opportunities for wider collaboration."

Blockade of IL-10 Signaling Ensures Mifamurtide Efficacy in Metastatic Osteosarcoma. (PubMed, Cancers (Basel)) - "We provide experimental evidence that the synergic use of an anti-IL-10 antibody in combination with mifamurtide causes a significantly increased mortality rate in highest-grade OS cells and lower metastasis in an in vivo model compared with mifamurtide alone. Overall, our data suggest that mifamurtide in combination with an anti-IL-10 antibody could be proposed as a new treatment protocol to be studied to improve the outcomes of OS patients."

Microbe-mediated intestinal NOD2 stimulation improves linear growth of undernourished infant mice. (PubMed, Science) - "We have identified cell walls isolated from Lp, as well as muramyl dipeptide and mifamurtide, as sufficient cues to stimulate animal growth despite undernutrition. Further, we found that NOD2 is necessary in intestinal epithelial cells for Lp-mediated IGF-1 production and for postnatal growth promotion in malnourished conventional animals. These findings indicate that, coupled with renutrition, bacteria cell walls or purified NOD2 ligands have the potential to alleviate stunting."
