Strand Therapeutics stays committed to making a positive impact for all, both in the lab and at home. We partnered with A Bed for Every Child to provide 10 beds for children in the Greater Boston area, which will help provide many nights of restful sleep and support children’s academic performance and overall health. Shoutout to all the Strands who rolled up their sleeves and built beds!

Yesterday, our CEO and co-founder @DrSynbio sat down with @MTSlive and explained the technology behind STX-003. Until now, genetic medicine has been limited by its own payloads: molecules that are powerful enough to kill cancer are also often toxic to healthy cells. But with this molecular “encryption” technology, Strand is building mRNA medicines that selectively turn on in tumors while sparing healthy cells. Watch the full interview to learn more: youtu.be/uT86Cpy4x0g?t=6356
Strand Therapeutics CEO @DrSynbio explains how a new cancer trial could break a 25-year barrier in genetic medicine by getting IV-delivered mRNA to work beyond the liver: "We've started our clinical trial, ASCENT-1, which is the first dosing of STX-003, the world's first IV deliverable messenger RNA that targets to solid tumors." "For us in the genetic medicine field, it's a huge leap forward because for the last 25 years we've been stuck only able to intravenously dose genetic medicines to the liver." "The much broader story is that medicine is really becoming programmable, and it is becoming programmable at a time that, between AI, synthetic biology, and other technologies, are really hitting a verticalization arc in our ability to design new medicines." @StrandTx

Strand is bringing two presentations to #SITC26 this week, covering our programs STX-001 and STX-003. Fresh off her late-breaking presentation at ESMO, @ProfGLongMIA of @MelanomaAus will be presenting updated Phase I data on STX-001’s durable, systemic anti-tumor activity. As our first clinical program, STX-001 provided preliminary evidence that a therapy injected directly into a tumor may activate the immune system throughout the body. It helped lay the foundation for STX-003, our flagship clinical program that just dosed its first cohort of patients in ASCENT-1. Trial principal investigator, @MLJohnsonMD2 of @SarahCannonDocs, will present on the design of ASCENT-1, which is evaluating STX-003 as a systemically delivered, programmable self-replicating mRNA engineered to switch on selectively inside tumors. 📅 Friday, November 6 | Phoenix Convention Center 📢 STX-001 oral: 4:55–5:05 pm MT, West Building-300 Level, 301BC 🧬 STX-003 poster: North Building-Lower Level, Exhibition Halls 4-6 You can find more details here: businesswire.com/news/home/2… We’ll see you there.

Strand made an appearance last week in Times Square! Thanks to @Nasdaq for featuring our STX-003 news on the tower. STX-003 is our systemic programmable mRNA therapy, now being administered to patients in the ASCENT-1 clinical trial. The drug is designed to deliver IL-12, a potent cancer-killing immune signal, to tumors throughout the body while staying silent in healthy cells.

Strand has won Best Biotechnology Startup at the 2026 Prix Galien USA Awards, America’s preeminent prize for leading-edge scientific advances. The recognition comes right as we’ve dosed the first patients in ASCENT-1, our trial testing STX-003, an intravenously delivered programmable mRNA therapy to tumors throughout the body. The payload is the potent cancer-killing immune signal IL-12, a molecule with the power to eradicate tumors that’s been sidelined for decades by its toxicity. Controlling where these powerful payloads activate, down to the cell, is what we believe will form the foundation of the next era of medicine.

The first patients have been dosed in ASCENT-1, our Phase 1 trial of STX-003, an IV-delivered mRNA therapy designed to bring the potent immune-activating protein IL-12 to tumors throughout the body. It’s our first systemic test of programmable mRNA, and it’s built to solve a problem that’s defined cancer treatment for decades: the drugs powerful enough to kill tumors often damage healthy tissue, too. STX-003 is designed to sidestep that problem by selectively activating where it’s needed. We believe it’s just the start of what the platform could make possible in this era of next-generation delivery. If this works, the same technology could carry other therapeutic proteins, opening the door to a new class of programmable medicines. Our CEO and co-founder @DrSynbio co-founder, President, and Head of R&D @tasuku_kitada take a moment to discuss this milestone and how this trial is a test of a fundamentally new approach to treating disease. 🧬 Learn more: businesswire.com/news/home/2…

Last month, we welcomed about 20 PhD students and postdocs from the @thebiotechclub to our Boston office for an afternoon of touring our space and hearing from our team – including a talk and Q&A with co-founder, President, and Head of R&D @tasuku_kitada, alongside scientists from our program management and translational medicine groups. This week, Tasuku’s conversation with Harvard Biotech Club’s The Pulse podcast is live and he talks through Strand's programmable mRNA platform, his path from biotech investing back into R&D, and what could be next for oncology and autoimmune disease. Listen to the full conversation: hbcpulse.substack.com/p/tasu…

@elonmusk is right about the acceleration implication, but mRNA isn’t software. It’s chips. That distinction matters. The mRNA molecule is the programmable hardware layer: a biological device that carries instructions into a cell and gets translated by the cell’s machinery.
Replying to @EricTopol
Despite its obvious misuse during Covid, mRNA has tremendous promise for curing diseases. Artificial RNA essentially makes curing diseases a software problem.

Last week, our co-founder and CEO @DrSynbio joined Endpoints News and Roivant Sciences CEO @gline for a live debate on China's impact on biotech. Jake made the case that while protectionism is an important consideration, we have to stay focused on acceleration. He pointed to Australia's clinical trial capacity running at four times the U.S. rate despite having a tenth of the population. This isn’t just a sign of how much room there is to move faster here. The gap is felt by patients, too. 86% of non-metro U.S. hospitals don't run clinical trials, meaning many patients have to leave home to access experimental treatments.

The US has spent the last decade spending more and more money to develop less innovative medicines, says Jake Becraft, Strand Therapeutics CEO. Any response to China’s increasing biotech edge has to include reforms that address that root issue, he said during Endpoints’ China event.

Congratulations to our co-founder and CEO, @DrSynbio, on being named an @EY_US Entrepreneur Of The Year® 2026 New England Award winner! This recognition reflects a mission that every person at Strand shows up for every day: programming mRNA to sense, decide, and act inside the body, so that therapies reach more patients, treat more diseases, and do so more scalably than ever before. That mission is what keeps us moving forward.
