Diffusion Pharmaceuticals Reports Third Quarter 2019 Financial Results and Provides Business Update

Commenced Patient Enrollment in Phase 2 On-Ambulance TSC Clinical Trial for the Treatment of StrokeReported Favorable Safety Data in Glioblastoma Multiforme Phase 3 Run-in StudyCHARLOTTESVILLE, Va., Nov. 11, 2019 (GLOBE NEWSWIRE) — Diffusion Pharmaceuticals Inc. (Nasdaq: DFFN), a cutting-edge biotechnology company developing new treatments for life-threatening medical conditions by improving the body’s ability to bring oxygen to the areas where it is needed most, today reported financial results for the three and nine months ended September 30, 2019 and provided a business update.
Recent business highlights include the following:Reported news that based on favorable safety data in the TSC dose-escalation run-in study, the Data Safety Monitoring Board (DSMB) recommended continuation of the INTACT trial using the highest dose administered, 1.5 mg/kg of TSC during the adjuvant treatment period. The INTACT trial is comparing SOC radiation therapy and chemotherapy plus TSC, against SOC alone. In Phase 2 testing, TSC demonstrated a nearly four-fold improvement in overall survival at two years for the subset of inoperable GBM patients, compared with the control group of GBM patients. Diffusion is seeking a partner to continue development of TSC in GBM.
 During October, the Company commenced enrollment in its on-ambulance Phase 2 clinical trial testing TSC for the treatment of acute stroke.  In cooperation with researchers at the University of California Los Angeles (UCLA) and the University of Virginia (UVA), the 160-patient trial, named PHAST-TSC (Pre-Hospital Administration of Stroke Therapy-TSC), will involve 23 hospitals across urban, suburban and rural areas in Los Angeles County and Central Virginia. Results from the trial may be available in just under two years.  The first patients were treated in Virginia.  The Company is qualifying sites in Los Angeles and expects the study to begin enrollment there in the coming weeks.“We are pleased with the progress during the third quarter and recent weeks in developing our lead compound to treat hypoxic conditions,” said David Kalergis, chairman and chief executive officer of Diffusion. “A highlight was beginning patient enrollment in our PHAST-TSC Phase 2 study after detailed preparations to train the ambulance first responders and to certify each site. We expect enrollment to accelerate in the three sites participating in Virginia.  Once the sites in Los Angeles are brought on board, the trial should be in full swing with data anticipated to be available in 18 to 24 months.  The administration of TSC to stroke patients is an exciting opportunity to potentially safely mitigate some of the devastating effects of a stroke through immediate treatment while the patient is in the ambulance.  In addition, the Notice of Intention to Grant a patent earlier this year from the European Patent Office for the use of TSC in combination with tPA – the only currently available drug for the treatment of ischemic stroke – further supports the commercial prospects of TSC.”Third Quarter Financial ResultsResearch and development expenses were $1.7 million for the third quarter of 2019, compared with $1.2 million for the third quarter of 2018. The increase was mainly attributable to a $0.6 million increase in expense related to the commencement of the Phase 2 stroke trial and an increase in manufacturing expense of $0.2 million, offset by a decrease of $0.2 million in expense related to the Phase 3 GBM trial and a $0.1 million decrease in salary and other expense.General and administrative expenses were $1.3 million for the third quarter of 2019, compared with $1.6 million for the third quarter of 2018. The decline was mainly due to lower salaries and wages, along with lower stock compensation expense, partially offset by an increase in insurance and other costs.Net cash used in operating activities during the first nine months of 2019 was $7.4 million, compared with $7.7 million used during the prior-year period.Diffusion had cash and cash equivalents of $6.1 million as of September 30, 2019, compared with $8.0 million at December 31, 2018.About Diffusion Pharmaceuticals Inc.Diffusion Pharmaceuticals Inc. is an innovative biotechnology company developing new treatments that improve the body’s ability to bring oxygen to the areas where it is needed most, offering new hope for the treatment of life-threatening medical conditions.Diffusion’s lead drug TSC was originally developed in conjunction with the Office of Naval Research, which was seeking a way to treat hemorrhagic shock caused by massive blood loss on the battlefield. Evolutions in research have led to Diffusion’s focus today: Fueling Life by taking on some of medicine’s most intractable and difficult-to-treat diseases, including stroke and GBM brain cancer. In each of these diseases, hypoxia – oxygen deprivation of essential tissue in the body – has proved to be a significant obstacle for medical providers and the target for TSC’s novel mechanism.In September 2018 its on-ambulance PHAST-TSC acute stroke protocol was granted FDA clearance to proceed and the Company began enrolling patients in this Phase 2 study in October 2019. In July 2019 the Company reported favorable safety data in a 19-patient dose-escalation run-in study to its Phase 3 INTACT program, using TSC to target inoperable GBM brain cancer.  Additional preclinical data supports the potential use of TSC as a treatment for other conditions where hypoxia plays a major role, such as myocardial infarction, respiratory diseases such as COPD, peripheral artery disease, and neurodegenerative conditions such as Alzheimer’s and Parkinson’s disease.In addition, RES-529, the Company’s PI3K/AKT/mTOR pathway inhibitor that dissociates the mTORC1 and mTORC2 complexes, is in preclinical testing for GBM.Diffusion is headquartered in Charlottesville, Virginia – a hub of advancement in the life science and biopharmaceutical industries – and is led by CEO David Kalergis, a 30-year industry veteran and company co-founder. Forward-Looking StatementsTo the extent any statements made in this news release deal with information that is not historical, these are forward-looking statements under the Private Securities Litigation Reform Act of 1995.
