FARMINGTON HILLS, Mich., March 08, 2024 (GLOBE NEWSWIRE) -- Ocuphire Pharma, Inc. (Nasdaq: OCUP), a clinical-stage biopharmaceutical company focused on developing and commercializing small-molecule therapies for the treatment of retinal and refractive eye disorders, today announced financial results for the fourth quarter and full year ended December 31, 2023, and provided a corporate update. “Ocuphire had a successful 2023, with notable achievements on the regulatory and development fronts, paving the way for further progress in the year ahead,” said George Magrath, M.D., M.B.A., M.S., CEO of Ocuphire. “Our strategic focus is on the advancement of our retina pipeline, and we are preparing our late-stage clinical program to progress APX3330 in diabetic retinopathy (“DR”). We believe APX3330 may represent a promising oral treatment option for delaying disease progression in patients with non-proliferative diabetic retinopathy who otherwise are monitored and untreated until they progress to sight-threatening disease.” Clinical and Regulatory Updates APX3330 In January 2023, Ocuphire reported top-line efficacy and safety results from the ZETA-1 Phase 2 trial conducted in 103 subjects with DR, including moderately severe and severe non-proliferative DR (“NPDR”) and mild proliferative DR (“PDR”), as well as patients with diabetic macular edema without loss of central vision. Trends toward efficacy were seen on the ≥3-step worsening on a binocular diabetic retinopathy severity scale (“DRSS”) Person Scale. APX3330 also demonstrated favorable safety and tolerability in diabetic patients.In October 2023, Ocuphire held an End-of-Phase 2 meeting with the FDA and aligned on the registrational primary endpoint of 3-step or more worsening on binocular DRSS Person scale.In February 2024, Ocuphire submitted a Special Protocol Assessment (“SPA”) to seek agreement on the clinical trial protocol and statistical analysis plan for Phase 3. Specifics on the study design and the anticipated timing will be shared if and when an agreement is reached with the FDA. Phentolamine ophthalmic solution 0.75% (“PS”) In September 2023, Ocuphire and Viatris, Inc. (“Viatris”) announced FDA approval of PS under the brand name RYZUMVI™ for the treatment of pharmacologically-induced mydriasis. In 2023, the Company received a cash payment in the amount of $10 million from Viatris upon achieving this regulatory approval milestone in connection with its license agreement with Viatris. RYZUMVI is expected to launch in the first half of 2024.The Company received an agreement from the FDA under a SPA for the clinical trial protocol and planned statistical analysis of the LYNX-2 Phase 3 trial to evaluate PS for the proposed indication for the treatment of decreased visual acuity under dim (mesopic) light conditions after keratorefractive surgery. Viatris is expected to continue Phase 3 development of this indication in the first half of 2024.The VEGA-2 Phase 3 study achieved a primary endpoint in presbyopia. Viatris is expected to continue Phase 3 development in the first half 2024.Development of PS in treatment of presbyopia and in decreased visual acuity under dim (mesopic) light conditions after keratorefractive surgery is expected to be funded by Viatris, under terms of the license agreement with Viatris. Corporate Updates In August 2023, Ocuphire entered into a common stock purchase agreement with Lincoln Park Capital Fund, LLC (“LPC”), pursuant to which Ocuphire has the sole right, but not the obligation, to direct LPC to purchase up to $50 million of shares of our common stock.In November 2023, Ocuphire appointed George Magrath, M.D., M.B.A., M.S., as Chief Executive Officer and as a member of the Board of Directors. Dr. Magrath succeeded Rick Rodgers, M.B.A., Interim Chief Executive Officer and President. Mr. Rodgers remains a member of the Board of Directors.In November 2023, Ocuphire appointed Joseph (Joe) K. Schachle, M.B.A., as Chief Operating Officer.In February 2024, Ocuphire appointed Nirav Jhaveri, C.F.A, M.B.A. as Chief Financial Officer and Ashwath (Ash) Jayagopal, Ph.D., M.B.A. as Chief Scientific and Development Officer. Financial Highlights for the Fourth Quarter and Full Year Ended December 31, 2023 As of December 31, 2023, Ocuphire had cash and cash equivalents of approximately $50.5 million. Based on current projections, management believes the present cash on hand will be sufficient to fund operations into mid-2025. License and collaboration revenue was $1.7 million and $19.0 million for the fourth quarter and year ended December 31, 2023, respectively, compared to $39.9 million for both the fourth quarter and year ended December 31, 2022. Revenue during 2023 was derived in part from a milestone payment of $10.0 million received from Viatris and attributed to the FDA’s approval of RYZUMVI for the treatment of pharmacologically induced mydriasis. The balance of the revenue recognized during calendar year 2023 related to the output of research and development services in connection with the Viatris License Agreement. Revenue during calendar year 2022 was derived from the Viatris License Agreement signed in the fourth quarter, and to a lesser extent, from the reimbursement by Viatris of research and development services. General and administrative expenses were $3.3 million and $12.0 million for the fourth quarter and year ended December 31, 2023, respectively, compared to $2.1 million and $7.3 million for the fourth quarter and year ended December 31, 2022. The increase year-over-year was attributed to payroll related costs, stock-based compensation, other personnel related costs, professional services fees, legal support, and business development activities and other costs. General and administrative expenses included $2.4 million and $1.1 million in stock-based compensation expense during the years ended December 31, 2023 and 2022, respectively. Research and development expenses were $3.8 million and $17.7 million for the fourth quarter and year ended December 31, 2023, respectively, compared to $3.6 million and $14.4 million for the fourth quarter and year ended December 31, 2022. The increase was primarily attributable to increased clinical costs for PS, increased manufacturing and toxicology activities for APX3330 and PS, higher payroll costs including stock-based compensation, and other operating expenses. These were offset by a decrease in regulatory activities. Pursuant to the Viatris License Agreement, Ocuphire’s budgeted research and development expenses related to the development of PS are fully reimbursed by Viatris. Research and development expenses included $1.1 million and $0.7 million in stock-based compensation expense during the years ended December 31, 2023, and 2022, respectively. Net loss was $4.8 million (or ($0.21) per basic and diluted share) and $10.0 million (or ($0.46) per basic and diluted share), for the fourth quarter and year ended December 31, 2023, respectively. This compared to net income of $33.9 million (or $1.63 per basic share and $1.58 per diluted share) and $17.9 million (or $0.90 per basic share and $0.87 per diluted share), for the fourth quarter and the year ended December 31, 2022, respectively. For further details on Ocuphire’s financial results, refer to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, to be filed with the Securities and Exchange Commission (the “SEC”). About Ocuphire Pharma Ocuphire is a clinical-stage ophthalmic biopharmaceutical company focused on developing and commercializing small-molecule therapies for the treatment of retinal and refractive eye disorders. Ocuphire’s lead retinal product candidate, APX3330, is a small-molecule inhibitor of Ref-1 (reduction oxidation effector factor-1 protein). Ref-1 is a regulator of the transcription factors HIF-1α and NF-κB. Inhibiting REF-1 reduces levels of vascular endothelial growth factor (“VEGF”) and inflammatory cytokines which are known to play key roles in ocular angiogenesis and inflammation. APX3330 is an oral tablet to be administered twice per day for the treatment of DR. A Phase 2 study in subjects with DR and an End-of-Phase 2 meeting have recently been completed, and a SPA is planned to be submitted. DR affects approximately 10 million people with diabetes and is projected to impact over 14 million Americans by 2050. DR is classified as NPDR, the early stage of the disease in which symptoms may be mild or non-existent or PDR, which is the more advanced stage of diabetic eye disease that can be highly symptomatic with loss of vision. Approximately 8 million DR patients have NPDR that will progress to PDR, if left untreated. Despite the risk for visual loss associated with this disease, over 90% of NPDR patients currently receive no course of treatment apart from observation by their eye care specialist until they develop sight-threatening complications. This is partially attributed to the currently approved therapies for this disease. APX3330 as an oral tablet has the potential to be an early, non-invasive treatment for the 8 million NPDR patients in the U.S. Treatment with APX3330 is expected to delay or prevent progression of NPDR, thereby reducing the need for expensive intravitreal injections with anti-VEGF therapies and reducing the likelihood of vision loss due to DR. Ocuphire has also in-licensed APX2009 and APX2014, which are second-generation analogs of APX3330. The unique mechanism of action of these Ref-1 inhibitors, which reduce both angiogenesis and inflammation, could potentially be beneficial in treating other retinal diseases such as age-related macular degeneration and geographic atrophy. Ocuphire is currently evaluating local delivery routes in addition to the systemic (oral) route as part of its pipeline expansion in retinal therapies. Ocuphire also has a partnership with Viatris, Inc. to develop and commercialize PS (initially known as Nyxol). PS is a non-selective alpha-1 and alpha-2 adrenergic antagonist designed to reduce pupil size by uniquely blocking the alpha-1 receptors found on the iris dilator muscle without affecting the ciliary muscle. PS was approved by the FDA for the treatment for pharmacologically-induced mydriasis under the brand name RYZUMVI™ in September 2023. PS is also in Phase 3 clinical development for the treatment of presbyopia and for the treatment of decreased visual acuity under dim (mesopic or low) light conditions after keratorefractive surgery.

SAN DIEGO, March 06, 2024 (GLOBE NEWSWIRE) -- Cardiff Oncology, Inc. (Nasdaq: CRDF), a clinical-stage biotechnology company leveraging PLK1 inhibition to develop novel therapies across a range of cancers, today announced publications of five abstracts that will be presented in a poster session at the American Association for Cancer Research (AACR) Annual Meeting, taking place from April 5-10, 2024, in San Diego, California. “The posters we will be presenting at this year’s AACR meeting represent a broad view of the potential of onvansertib in several different cancer indications, including RAS-mutant mCRC, RAS-wild type mCRC, small cell lung cancer and ovarian cancer,” said Mark Erlander, Ph.D., Chief Executive Officer of Cardiff Oncology. “In RAS-mutated mCRC, we are showing the underlying mechanism through which the combination of onvansertib and bevacizumab targets the hypoxia response pathway. We believe this mechanism explains the strong clinical results we have seen in both our Phase 1b/2 and ONSEMBLE second-line RAS-mutated mCRC clinical trials. The additional posters provide new insights and rationale for future clinical trials in other cancer indications.” Details on the posters and corresponding abstracts are shown below. Poster Title: A phase 1b/2 clinical study of onvansertib in combination with FOLFIRI/bevacizumab revealed a new role of PLK1 in regulating the hypoxia pathway in KRAS-mutant colorectal cancer Session Title: Microenvironment, Immunity, and DNA Repair in Therapeutic Response Session Date and Time: Monday Apr 8, 2024: 9:00 AM - 12:30 PM PT Location: Poster Section 27, Poster Board #14, Abstract Number #2031 This abstract presents updated clinical data and biomarker analysis from the Phase 1b/2 study evaluating onvansertib in combination with FOLFIRI/bevacizumab for second-line treatment of KRAS-mutant metastatic colorectal cancer (mCRC) patients. Analysis of patient baseline characteristics revealed superior clinical benefit in patients not exposed to bevacizumab in first-line treatment (Bev-naïve) compared to Bev-exposed patients. Bev-naive patients exhibited higher objective response rates (73.3% versus 15.7%) and longer median progression-free survival (14.9 versus 7.8 months) compared to Bev-exposed patients. Preclinical studies, using KRAS-mutant colorectal cancer mouse models revealed robust antitumor activity of onvansertib in combination with bevacizumab and a novel role of onvansertib in regulating tumor vascularization. Further preclinical investigations showed that PLK1 regulates the hypoxia pathway in KRAS-mutant CRC cells through the modulation of the hypoxia-inducible factor 1 alpha, HIF1α, emphasizing the potential crosstalk between PLK1 and angiogenesis. These findings reinforce the rationale for exploring onvansertib in combination with FOLFIRI/bevacizumab for Bev-naïve mCRC patients with KRAS mutation. Poster Title: The PLK1 inhibitor, onvansertib, is active as monotherapy and in combination with cetuximab in RAS wild-type colorectal cancer patient-derived xenografts Session Title: Drug Resistance 2: Ras GTPase Session Date and Time: Monday Apr 8, 2024: 9:00 AM - 12:30 PM PT Location: Poster Section 24, Poster Board #12, Abstract Number #1934 This abstract focuses on the preclinical assessment of onvansertib’s antitumor activity in RAS wild-type colorectal cancer, as both a monotherapy and in combination with cetuximab, a monoclonal antibody targeting the epidermal growth factor receptor (EGFR). Employing patient-derived xenograft (PDX) models, the study highlights the robust antitumor efficacy of onvansertib monotherapy, in cetuximab-sensitive and -resistant RAS wild-type colorectal cancer models. Furthermore, the combination of onvansertib and cetuximab was highly effective, resulting in tumor regression in 90% of the PDXs. These compelling data strongly support the clinical development of onvansertib as a potential treatment for RAS wild-type colorectal cancer. Poster Title: A phase 2, randomized, open-label study of onvansertib in combination with standard-of-care (SoC) versus SoC alone for first-line treatment of RAS-mutant metastatic colorectal cancer(mCRC) Session Title: Phase II and Phase III Clinical Trials in Progress Session Date and Time: Tuesday, Apr 9, 2024: 1:30 PM - 5:00 PM PT Location: Poster Section 50, Poster Board #5, Abstract Number #CT275 This abstract describes a clinical trial in progress. Poster Title: The PLK1 inhibitor, onvansertib, synergizes with paclitaxel in small cell lung cancer Session Title: Kinase and Phosphatase Inhibitors 1 Session Date and Time: Sunday Apr 7, 2024: 1:30 PM - 5:00 PM PT Location: Poster Section 25, Poster Board #16, Abstract Number #606 This abstract outlines preclinical studies showing the promising potential of combining onvansertib with paclitaxel for small cell lung cancer (SCLC). The research reveals significant synergy of the combination in SCLC cell lines and demonstrates its robust antitumor activity in patient-derived xenograft models, including models resistant to the standard therapy cisplatin. Further insights into the combination's mechanism of action will be presented. These findings support that combining onvansertib with paclitaxel could emerge as a highly promising treatment strategy for SCLC. Poster Title: In vivo anti-tumor activity of onvansertib, a PLK1 inhibitor, combined with gemcitabine or carboplatin in platinum-resistant ovarian carcinoma patient-derived xenograft models Session Title: Application of Precision Medicine for Cancer Care Session Date and Time: Sunday Apr 7, 2024: 1:30 PM - 5:00 PM PT Location: Poster Section 39, Poster Board #13, Abstract Number #945 This abstract explores preclinically the potential of combining onvansertib with the chemotherapeutic agents carboplatin or gemcitabine for platinum-resistant high-grade ovarian carcinoma. Using patient-derived xenografts, we demonstrated robust efficacy for both combinations, coupled with favorable tolerability. These data underscore the potential of onvansertib to improve the efficacy of the standard-of-care carboplatin and gemcitabine for patients with platinum-resistant high-grade ovarian carcinoma. The abstracts are available on the AACR Online Program and will be published in the online Proceedings of the AACR. Following presentation, the posters will be posted to the "Scientific Presentations" section of the Cardiff Oncology website. About Cardiff Oncology, Inc. Cardiff Oncology is a clinical-stage biotechnology company leveraging PLK1 inhibition, a well-validated oncology drug target, to develop novel therapies across a range of cancers. The Company's lead asset is onvansertib, a PLK1 inhibitor being evaluated in combination with standard-of-care (SoC) therapeutics in clinical programs targeting indications such as RAS-mutated metastatic colorectal cancer (mCRC) and metastatic pancreatic ductal adenocarcinoma (mPDAC), as well as in investigator-initiated trials in small cell lung cancer (SCLC) and triple negative breast cancer (TNBC).

About Ocuphire Pharma Ocuphire is a clinical-stage ophthalmic biopharmaceutical company focused on developing and commercializing small-molecule therapies for the treatment of retinal and refractive eye disorders. Ocuphire’s lead retinal product candidate, APX3330, is a first-in-class small-molecule inhibitor of Ref-1 (reduction oxidation effector factor-1 protein). Ref-1 is a regulator of the transcription factors HIF-1α and NF-κB. Inhibiting REF-1 reduces levels of vascular endothelial growth factor (“VEGF”) and inflammatory cytokines which are known to play key roles in ocular angiogenesis and inflammation. Through inhibition of Ref-1, APX3330 normalizes the levels of VEGF to physiologic levels, unlike biologics that deplete VEGF below the levels required for normal function. APX3330 is an oral tablet to be administered twice per day for the treatment of diabetic retinopathy (“DR”). A Phase 2 study in subjects with DR and an End-of-Phase 2 meeting have recently been completed, and a Special Protocol Assessment (“SPA”) is planned to be submitted to the FDA. DR affects approximately 10 million people with diabetes and is projected to impact over 14 million Americans by 2050. DR is classified as Non-Proliferative Diabetic Retinopathy (“NPDR”), the early stage of the disease in which symptoms may be mild or non-existent or Proliferative Diabetic Retinopathy (“PDR”) which is the more advanced stage of diabetic eye disease that can be highly symptomatic with loss of vision. Approximately 8 million patients with DR have NPDR that will progress to PDR if left untreated. Despite the risk for visual loss associated with this disease, over 90% of NPDR patients currently receive no course of treatment apart from observation by their eye care specialist until they develop sight-threatening complications. This is due to the treatment burden of the frequent eye injections required with currently approved therapies for this disease. APX3330 as an oral tablet has the potential to be an early, non-invasive treatment for the 8 million NPDR patients in the U.S. Treatment with APX3330 is expected to delay or prevent progression of NPDR, thereby reducing the need for expensive intravitreal injections with anti-VEGF therapies and reducing the likelihood of vision loss due to DR. Ocuphire has also in-licensed APX2009 and APX2014, which are second-generation analogs of APX3330. The unique mechanism of action of these Ref-1 inhibitors that reduces both angiogenesis and inflammation could potentially be beneficial in treating other retinal diseases such as age-related macular degeneration and geographic atrophy. Ocuphire is currently evaluating local delivery routes in addition to the systemic (oral) route as part of its pipeline expansion in retinal therapies. Ocuphire also has a partnership with Viatris, Inc. to develop and commercialize phentolamine ophthalmic solution 0.75%. Phentolamine is a non-selective alpha-1 and alpha-2 adrenergic antagonist designed to reduce pupil size by uniquely blocking the alpha-1 receptors found on the iris dilator muscle without affecting the ciliary muscle. In September 2023, the FDA approved RYZUMVI™ (phentolamine ophthalmic solution 0.75%) to treat pharmacologically induced mydriasis produced by adrenergic agonists (e.g., phenylephrine) or parasympatholytic agents (e.g., tropicamide). Phentolamine ophthalmic solution 0.75% is also in Phase 3 clinical development for the treatment of presbyopia and for the treatment of decreased visual acuity in dim (mesopic or low) light conditions after keratorefractive surgery.
