Insilico and Lilly Outline 'Prompt‑to‑Drug' Vision: Autonomous AI for drug discovery
Researchers from Insilico Medicine and Eli Lilly published a framework in ACS Central Science proposing a fully autonomous “prompt‑to‑drug” pipeline that links generative AI, automated synthesis, and iterative biological testing. The paper outlines integrated agentic systems that convert human prompts into candidate molecules and experimental plans, with feedback loops to refine designs. The authors present architecture, component examples, and potential workflows rather than clinical results. They note technical and validation gaps—data quality, assay automation, and safety oversight—that must be addressed before deployment. The publication signals escalating industry ambition to move discovery decisions from human-led cycles to machine‑led loops, with implications for R&D timelines, capital allocation, and regulatory expectations.

Element Debuts Vitari: $100 30X Genome, High‑Throughput Sequencing Push
Element Biosciences unveiled Vitari, a high‑throughput sequencing platform the company says can generate 3 terabytes per paired‑end 150 bp run in 36 hours and sequence a 30X human genome for $100. The platform targets large‑scale genomics centers and clinical labs seeking to cut per‑sample cost and turnaround time. Element positions Vitari as a direct challenge to entrenched incumbents by combining claimed throughput, speed and economics. Analysts note adoption will hinge on real‑world run metrics, reagent costs, and bioinformatics support; clinical and regulatory validation will determine whether the $100 genome claim translates into routine clinical use.

Guardant Eyes Screening Ramp, Buys MetaSight to Expand MCED Portfolio
Guardant Health guided to substantial screening growth in 2026 for its Shield colorectal cancer screening test and disclosed an acquisition of early cancer detection startup MetaSight Diagnostics. Management projected 2026 screening revenue of $162–$174 million and volumes of 210,000–225,000 tests, citing FDA approval for Shield and partnerships including Quest Diagnostics. Guardant paid $59 million upfront with up to $90 million in contingent consideration to acquire MetaSight, adding multi‑cancer early detection capabilities. Executives framed the move as a push to scale screening revenue and pipeline breadth; commercial upside depends on guideline inclusion, payer decisions and integration into provider ordering workflows.

Grail's Galleri Fails Primary Goal in NHS Trial — Stock Collapses
Grail reported that its large UK NHS‑Galleri multicancer early detection (MCED) trial did not meet the primary endpoint of a statistically significant reduction in Stage III–IV cancers. The company highlighted favorable trends in a pre‑specified subgroup but confirmed the study missed its main goal, triggering a near‑50% aftermarket stock decline. Grail executives said they expect the result will not necessarily derail FDA review or Medicare discussions and emphasized secondary signals and broader evidence packages. External experts including Eric Topol criticized the trial design and underscored that favorable subgroup trends do not substitute for a positive primary outcome. The result raises questions about MCED trial design, regulatory paths and commercial expectations for multi‑cancer blood tests.

FDA Reverses Refusal, Will Review Moderna's mRNA Flu Shot
After initially issuing a Refusal to File over comparator and study‑design concerns, the FDA reversed course and agreed to review Moderna’s seasonal influenza BLA for mRNA‑1010. Moderna said it reached agreement in a Type A meeting and proposed an age‑stratified regulatory pathway with a PDUFA date set for August 5, 2026. The reversal follows public scrutiny of the agency’s earlier decision and underlines regulatory volatility affecting novel vaccine modalities. FDA objections centered on the elderly comparator arm; Moderna proposed accelerated pathways and post‑marketing commitments for older adults. The episode highlights ongoing tension between innovative mRNA vaccine developers and evolving regulatory expectations.
