CHARLOTTESVILLE, Va., March 21, 2022 (GLOBE NEWSWIRE) -- Diffusion Pharmaceuticals(NASDAQ: DFFN) (“Diffusion” or the “Company”), an innovative biopharmaceutical company developing novel therapies that enhance the body’s ability to deliver oxygen to areas where it is needed most, today announced financial results for 2021 and provided a business update.
Corporate Strategy and Events
Business and financial highlights during 2021 and 2022 year-to-date include:
Declared Lead Development Program: The Company announced its intent to develop its novel, oxygen enhancing therapeutic, Trans Sodium Crocetinate (“TSC”), as an adjunct to standard of care therapy for hypoxic solid tumors in November 2021 (“Hypoxic Solid Tumor Program”).
Strengthened Balance Sheet: In February 2021, the Company raised approximately $34.5 million in gross proceeds through an up-sized, follow-on public offering of its common stock with proceeds to be used to fund research and development efforts for the TSC oxygenation trials (“Oxygenation Trials”) and corporate expenses. As of December 31, 2021, the Company reported a total of $37.3 million in cash and cash equivalents. As of March 18, 2022, the Company expects cash resources to fund operations through 2023.
Board Updates: Jane Hollingsworth appointed as new Board Chair in June 2021. Diana Lanchoney, M.D., and Eric Francois also elected to the Company’s board of directors in June 2021.
“We are pleased with the progress we achieved in 2021. We executed our corporate, clinical, and regulatory strategies, accelerating development of our lead product candidate, TSC. The capital we raised in the first half of 2021 allowed us to design and execute critical clinical trials to assess TSC's therapeutic potential in treating hypoxia-related conditions using three unique short-term experimental clinical models of oxygenation,” said Robert Cobuzzi, Jr., Ph.D., President and Chief Executive Officer of Diffusion.
Dr. Cobuzzi continued, "We believe the hard work demonstrated by our team in 2021 has laid a solid foundation for Diffusion's success in 2022. The initiation of our Altitude and ILD-DLCO trials in the last quarter of 2021 represented a significant inflection point on the route to achieving the goal of demonstrating TSC’s potential to enhance the body’s ability to deliver oxygen to areas where it is needed most and potentially provide a novel treatment option for a variety of conditions complicated by hypoxia. Moreover, in late 2021 we announced our intent to design and execute a clinical program to support the use of TSC as an adjunct treatment of hypoxic solid tumors as the next step in our efforts to realize TSC’s potential. We believe targeting hypoxic solid tumors is appropriate for TSC given the significant unmet medical need, the compelling preclinical and clinical data accumulated to date, and the current, intravenous formulation of TSC. The team has been working closely with our advisors to design a Phase 2 study that we believe, if successful, will help patients and enhance shareholder value."
Clinical Trial Execution & Strategy
TCOM Trial: In March 2021, the Company completed enrollment and dosing of all participants in its Phase 1 trial of TSC utilizing a transcutaneous oxygen monitoring (“TCOM”) device to evaluate the pharmacodynamic effects of TSC on peripheral tissue oxygenation in healthy, normal volunteers. As reported in June 2021, the topline results of the study showed TSC was safe and tolerable at all doses tested with no serious adverse events or dose-limiting toxicities. Furthermore, the Company announced that a positive trend in peripheral tissue oxygenation was observed among participants treated with TSC when compared to placebo-treated participants. This trend persisted through the one-hour, post-dosing measurement period. The Company believes the data from the TCOM Trial validate the thesis that TSC enhances oxygenation without causing hyperoxygenation. The data from the TCOM Trial have guided the design of the two additional Oxygenation Trials, as well as the design of the Hypoxic Solid Tumor Program.
Altitude Trial: In November 2021, Diffusion announced the dosing of the first participants in the Altitude Trial which was designed to evaluate the effects of TSC in normal healthy volunteers subjected to incremental levels of physical exertion while exposed to hypoxic and hypobaric conditions, or “simulated altitude.” Due to enrollment delays experienced during early 2022 related to the omicron variant wave of the COVID-19 pandemic, the Company now anticipates completing dosing in the second quarter of 2022 and topline results are expected to be reported within one to two months of study completion.
ILD-DLCO Trial: Subsequent to receiving Investigational New Drug application clearance from the U.S. Food and Drug Administration (“FDA”) in the third quarter of 2021, the Company announced the dosing of the first patient in the Phase 2 ILD-DLCO Trial in December 2021. The ILD-DLCO Trial was designed to evaluate the effects of TSC on carbon monoxide uptake through the lungs (“DLCO”) and into the bloodstream of interstitial lung disease (“ILD”) patients. DLCO measurement is used in the study as a surrogate measure of oxygen transfer efficiency, or uptake, from the alveoli of the lungs through the plasma, and onto hemoglobin within red blood cells. The Company intends to evaluate the effect of TSC on lung function as measured by DLCO, as well as distance covered in a standard six-minute walk test. Due to enrollment delays experienced during early 2022 related to the omicron variant wave of the COVID-19 pandemic, the effect of the omicron variant on patients with pulmonary diseases such as ILD, and staffing issues at the facilities where the ILD-DLCO Trial is being conducted, the Company now anticipates dosing to be completed by the middle of 2022, with topline results reported within two months of study completion.
Hypoxic Solid Tumor Treatment: In November 2021, based on the available preclinical and clinical data and the significant unmet medical need, including the TCOM and COVID-19 Trial results, the Company announced its intent to focus its near-term efforts on evaluating TSC as an adjunct to standard of care in the treatment of hypoxic solid tumors as a first indication. Solid tumors, which comprise approximately 90% of all adult cancers, are often affected by hypoxia, leading to treatment resistance, metastasis, and worse prognoses. Following, among other things, analyses and discussions with the Company’s oncology-focused SAB members and other external advisors over the last several months, Diffusion believes they have the necessary data to support the design and initiation of an appropriate Phase 2 trial as the first study in the Hypoxic Solid Tumor Program. The Company intends to file the study protocol with the FDA and expects to commence the trial in the second half of 2022, subject to FDA feedback and the availability of clinical drug supply.
2021 Financial Results
Diffusion had cash and cash equivalents of $37.3 million as of December 31, 2021, compared with $18.5 million as of December 31, 2020. Net cash used in operating activities during 2021 was $14.5 million, compared with $13.6 million used during 2020.
Research and development expenses were $8.5 million for 2021, compared with $9.4 million for 2020. The decrease was primarily attributable to lower project spending due to the completion and/or wind-down of the Company’s clinical studies evaluating TSC in COVID-19, glioblastoma multiforme brain cancer, and stroke.
General and administrative expenses were $7.4 million for 2021, compared with $6.4 million for 2020. The increase was primarily driven by increased headcount resulting in higher compensation expense and other costs associated with the hiring of new employees, as well as an increase in expense related to consulting services.
In 2021, the Company also recognized a non-recurring $8.6 million non-cash impairment charge related to the write down of its DFN-529 IPR&D asset.
