What the paper reports

Researchers identified Klebsiella phage 32 RNA polymerase as an alternative to T7 for RNA production. The enzyme tolerated a broad range of temperatures, pH values, and salt conditions. For an 11,551-nucleotide self-amplifying RNA retaining its native AU initiation, production was 9.3-fold higher than the T7 comparison. These laboratory results do not establish GMP-scale performance.

Why this paper is included

Highlights transcription options for long saRNA constructs; scale-up requires evaluating impurity profiles, capping compatibility, process robustness, and batch consistency.

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.
