SignalRx Pharmaceuticals Inc., Crystec Ltd., and ADYA Consulting SAGL are pleased to
announce a new collaboration to develop an inhaled dry powder formulation of SF2523 for the treatment
of pulmonary fibrosis, lung cancer and SARS-CoV-2 related illnesses.
SignalRx SF2523 is a novel, small molecule dual PI3K-BRD4 inhibitor with a synergistic action on two
pathways associated with the development of lung cancer and idiopathic pulmonary fibrosis (IPF). Combined
inhibition of both the PI3K and BRD4 pathways maximizes cellular effects in tumor and fibrosis models, and
enables higher dosing with greatly improved tolerability. As such, SF2523 offers potential advantages over
other drugs in the market and in development. In addition to its benefits in idiopathic pulmonary fibrosis
and cancer, SF2523 shows great promise as an anti-viral for the treatment of SARS-CoV-2 infection (COVID-
19). Recent in-vitro studies demonstrated that SF2523 blocks two orthogonal pathways necessary for SARSCoV-
2 pathogenesis in human cells, achieving a reduction in SARS-CoV-2 replication comparable to
The collaboration will involve Crystec utilizing its advanced mSAS® (modified supercritical antisolvent)
supercritical fluid particle engineering platform to achieve precise solid-state control of SF2523 while
simultaneously generating stable particles that are optimized for dry powder inhaled delivery. Typically,
mSAS® engineered particles achieve significantly higher levels of deep lung deposition than equivalent
particles manufactured using conventional technologies.
Inhaled SF2523 will undergo accelerated development with support from ADYA, who have expertise in
pharmaceutical pre-clinical and clinical program management, as well as a proven ability to deliver the
strategic investment and partnerships required to maximize the potential of SF2523 in its key therapeutic
Commenting on the opportunity, Matt Williams, CEO of SignalRx, said: “We are excited to combine the
unique therapeutic potential of SF2523 with the cutting-edge inhaled delivery capabilities of Crystec. With
support from ADYA, we hope to bring to the market a genuinely transformative drug for the treatment of
lung cancer, fibrosis, as well as COVID-19 infection and its longer-term complications.”
About SignalRx Pharmaceuticals Inc.
SignalRx Pharmaceuticals Inc. is a clinical stage company incorporated in Delaware, with operations in
Atlanta, Georgia and Tuscon, Arizona. The company is focused on developing effective anticancer treatments
inducing the immune system to attack cancer while blocking the most important and critical cell signaling
pathways that cancer cells use to proliferate, migrate, metastasize, and recruit a blood supply. The
company’s efforts are aimed at combining the maximum anticancer activity into its drugs by selectively
inhibiting as many important cancer targets as possible in a well-tolerated non-toxic manner, whilst engaging
the immune system machinery to achieve maximum synergistic anticancer effects. SignalRx is actively
pursuing other opportunities in complementary therapeutic indications.
About Crystec Ltd.
Crystec is a UK-based crystal and particle engineering company, applying proprietary ‘mSAS®’ (modified
Supercritical Anti-Solvent) drug delivery technology to improve the performance of medicines. Crystec’s
technology enables drug molecules to be crystallized in new forms and novel particles to be manufactured
in ways that can greatly enhance their clinical effect. The mSAS® process is highly efficient, stable, fully
scalable and is approved by regulatory authorities. Crystec works with the global pharmaceutical and health
care industry to solve drug particle formation, formulation and process challenges. The company is also
developing innovative therapies in important areas of unmet clinical need, including women’s health,
urology and respiratory disease.
