Excited to contribute to this effort. Solving this problem will require multiple shots on goal. We at HDT Bio will be contributing our experience in manufacturing of long RNA molecules and simplified formulation with LION to create safe, yet potent, personalized drugs. More information to come soon!
ARPA-H grants up to $125M for making custom RNA therapies on demand, with applications in gene editing and cancer vaccines. One of the recipients is Waterfall Scientific, cofounded by former Moderna CSO Melissa Moore. Details in my story for @endpts.com: endpoints.news/arpa-h-award...
Excited that our work to mature a new vaccine and therapeutics platform, with application of the technology to an important tick borne disease, is getting some recognition. Of course, where the rubber meets the road is in the data. More to come on that soon! www.prnewswire.com/news-release...

4/ To capitalize on that finding, we established a VHH discovery workflow to support the development of repRNA-encoded VHHs using EV-D68 as a model pathogen. We recently completed a full vaccine development campaign for that virus described here: www.science.org/doi/abs/10.1...

2/ This builds directly on our prior repRNA antibody work showing you can drive potent in vivo expression of mAbs from RNA platforms: www.cell.com/molecular-th...

In my new Nucleic Acid Insights interview, I discuss the evolving science of RNA therapeutics. Addresses safety, manufacturing, and delivery, and how HDT Bio’s LION platform moves beyond LNPs to enable potent, localized, extrahepatic RNA delivery. www.insights.bio/nucleic-acid...

Excited to announce our new ARPA-H award to “Close the DOORs” mapping how viruses exploit human cells and learning how to shut them. Grateful to @arpa-h.bsky.social and our amazing team! 🔗 www.mountsinai.org/about/newsro... #ARPAH #Virology #HostPathogen #Innovation #Science

Follow up publication describing immunogenicity and efficacy in NHPs of historical and contemporary H5N1 vaccine compositions against challenge with contemporary cattle virus isolate. What we concluded in mice did not translate to NHPs. www.science.org/doi/10.1126/...
New paper! In collaboration with NIAID, we asked: how effective are vaccines designed against historical #H5N1 viruses in naïve mice challenged with the contemporary cattle virus? Turns out that the new isolates are different enough to warrant further evaluation of updated vaccine compositions. 🧪
Happy to announce that we have initiated a phase I clinical trial to evaluate safety and immunogenicity of our LION/repRNA vaccine against #CCHF. This is the culmination of a great partnership with NIAID, UTMB, and our federal sponsors. More to come! www.prnewswire.com/news-release...

Just published! Here we report immunogenicity and efficacy of our replicon RNA vaccine against Crimean-Congo hemorrhagic fever in a cynomolgus macaque model of #CCHFV infection. Stay tuned as we advance this candidate in clinical trials. www.thelancet.com/journals/ebi...
Even our project, which directly addressed the tolerability and upper respiratory tract immunity gaps highlighted by RFK Jr, was impacted by this decision. They clearly didn’t review the 22 contracts/grants and the data already generated under taxpayer investment. We are 3 yrs into our program…
Pandemic preparedness in the US has been leveled a crippling blow with the cancellation of multiple #BARDA contracts to help develop mRNA vaccines. No other vaccine platform produces vaccine so quickly; without mRNA, Americans will have a long wait for pandemic vax. www.statnews.com/2025/08/05/m...
🧪 New paper from our team at HDT Bio highlighting that combo repRNA vaccines can lead to excessive innate activation that ultimately inhibits vaccine effectiveness in NHPs. Use of repRNA formulations with restricted biodistribution can alleviate systemic innate response and restore effectiveness.

Our latest preprint is now available doi.org/10.1101/2025...! Led by my postdoc, Luqiang Guo @luqiang.bsky.social, we determined a ~2.4 A resolution structure of the hantavirus glycoprotein tetramer on the surface of VLPs. Also determined structures of dimers of tetramers and Fab-bound tetramers.
I didn’t realize you could filter the posts of who you follow! The paper feed is just what I was looking for.
There is so, so much good science being shared and discussed on bsky right now. The news of its demise is quite backwards. If you are having trouble finding it among all of the very important political news, use the papersky feed that filters posts you follow to just papers: bsky.app/profile/pape...

Collab btwn NIAID (Dr. Andrea Marzi’s lab) and HDT Bio just published! 🧪 Filovirus gold-standard VSV vax platform compared to LION/repRNA (each encoding same antigen seq) for ability to provide single-dose protection in guinea pigs against Sudan virus challenge 🧵(1/2) www.nature.com/articles/s41...
I noticed this statement from NIH regarding durability of the inactivated approach. I didn’t see any durability data in the published studies of this candidate. Anyone aware of durability studies performed using inactivated virus platforms? I did one experiment in grad school (in thread below).
There are a lot of questions being asked about the awarding of a $500M grant to an #NIH team to develop a new (old) vaccine platform that could be used for a "universal" #flu vaccine. www.statnews.com/2025/05/03/n...
In fig 5 of the 🔗 paper, I compared the durability of protective immunity elicited by same doses of the exact same virus/vaccine (non replicating). One was inactivated with formalin (open circles); the other was not (closed circles). Inactivation killed durability. www.nature.com/articles/nm....

Ok scientists & those who love science 🧪: here is another exhortation. Call Congress TODAY about the freeze on NIH Council Meetings and Study Sections. Emphasize that this means NO new grants are being funded & labs will soon start to shut down and fire employees. Phone numbers are at: 5calls.org

Scientists, we need your stories! Post a 2-minute video on whatever social media apps you use. Show us your empty labs, tell us about the grant you are waiting for, and talk about why you do what you do. Tag @c4lifesciences.bsky.social and #Cuts2Science Tag your Members of Congress!
