What the paper reports

Investigators combined mRNAs encoding an EpCAM-directed T-cell engager, IL-12, and GM-CSF through intratumoral nanoparticle administration. In partially humanized mouse xenograft experiments, the combination altered immune activity in both injected and uninjected tumors and inhibited tumor growth. The study supports localized production of several immune proteins, while the model cannot establish safety or effectiveness across human cancers.

Why this paper is included

Supports local multicomponent mRNA immunotherapy and distant-tumor effects; partially humanized mouse models provide limited predictions of human systemic toxicity.

The interpretation above is analysis, not a conclusion attributed to the original source.

Moderna raises 2026 revenue outlook after third-quarter growth

Moderna reported third-quarter 2026 revenue of $1.3 billion, up 29% year over year, and GAAP net income of $162 million, compared with a $200 million loss a year earlier. It raised expected full-year revenue growth to 15%–25% from up to 10%. The company attributed quarterly growth mainly to international COVID vaccine sales supported by government partnerships.

Ethris reports exploratory antiviral and exposure-response signals for nasal ETH47 in asthma

Ethris reported topline results from a randomized Phase 2a rhinovirus-challenge study involving 50 adults with asthma. A single nasal dose of ETH47, an interferon-lambda-encoding mRNA candidate, produced local expression and lower day-two viral load. Symptom improvements were described as numerical trends; exposure-response subgroup findings remain exploratory, without established clinical efficacy.

Moderna reports initial mRNA-2808 T-cell engager results in multiple myeloma

Moderna reported initial Phase 1/2 MyEngage findings for mRNA-2808, which encodes three T-cell engagers. Four confirmed responses occurred among 11 response-evaluable patients. Twelve patients had received treatment; Grade 3 or higher treatment-related adverse events occurred in 41.7%. These small, uncontrolled findings are preliminary and do not establish comparative benefit.
