Taking RNA Medicines
to New Heights

We are Problem Solvers
and Proven Drug Developers.

At DTx, we are a group of flexible, innovative thinkers who are determined to solve one of the biggest challenges limiting the development of genetic medicines.  Anchored by our expertise in RNA therapeutics and our proprietary FALCON™ platform, we’ve developed a unique pipeline of novel therapeutic candidates to help patients with ocular, neuromuscular and CNS diseases.

To advance the FALCON platform toward and into clinical development, DTx has raised more than $100M in combined investment from world’s leading healthcare investors including RA Capital and Access Biotechnology, pharmaceutical companies such as Eli Lilly, the National Institute of Health (NIH), and research foundations such as the CMT Research Foundation (CMTRF).

Unlocking Oligonucleotide Therapeutics.

RNA medicines can address countless disease targets, currently undruggable by small molecules or biologics, by inhibiting or altering the expression of disease-causing genes.

Historically, this class of medications, which includes siRNA and antisense oligonucleotides, has been hampered by challenges with drug delivery.

DTx Pharma FALCON technology addresses the fundamental challenges associated with delivering RNA therapeutics by leveraging fatty acid receptors for cellular uptake and leveraging fatty acid albumin interactions to promote biodistribution.  Our team has created a platform called FALCON™ (Fatty Acid Ligand Conjugated OligoNucleotide) that promotes efficient non-toxic cellular uptake and enhanced systemic bioavailability. We combine the latest in RNA technology with our own proprietary IP to create novel therapies that can efficiently reach targets beyond the liver, taking RNA therapeutics to new heights.


Fatty Acid Ligand Conjugated OligoNucleotide

DTx’s strategy to advance our unique platform is to:

Focus on genetically-defined diseases

Prioritize indications with limited competition where DTx can own the space

Explore partnering opportunities across on-strategy therapeutics areas and in novel therapeutic areas where our FALCON technology can provide value

Our Lead Programs


DTx Pharma is pursuing numerous opportunities in ophthalmology as there are a large number of indications with significant unmet need where RNA therapeutics are attractive and because RNA therapeutics have significant advantages over gene therapies in terms of distribution to cells with underlying genetic lesions.  Further, RNA therapeutics can last as much as a year following a single injection.  Our most advanced program in the eye targets a disease called retinitis pigmentosa (RP).
We anticipate moving our first clinical candidates for RP into clinical development in 2022.


Our FALCON platform enables delivery of RNA therapeutics to key tissues impacted in neuromuscular diseases, including muscle, heart and peripheral nerves.  We are pursuing multiple genetic diseases driven by genetic defects in skeletal muscle, cardiac muscle and the peripheral nervous system.  We anticipate moving our first clinical candidates for neuromuscular disease(s) into clinical development in 2023.

Other Research Areas

Our FALCON platform also has the potential to address neurodegenerative, cardiovascular, immune and oncology indications. DTx Pharma has been awarded multiple grants from the NIH (NCATS, NIA), and foundations including the TPEP program of the Alzheimer’s Association and Rainwater Charitable Trust and the CMTRF to advance its efforts to treat CNS diseases.
