The safety and effectiveness of nafamostat is being assessed in the NEPHRO CRRT registrational trial in 166 patients at up to 14 clinical sites Primary endpoint in the NEPHRO CRRT study is measured over the first 24 hours, with patients completing the study after 72 hours Dr. Stuart Goldstein, a world-renowned nephrologist, is the first physician to enroll a patient in the NEPHRO CRRT study SAN MATEO, Calif., Aug. 19, 2024 /PRNewswire/ -- Talphera, Inc. (Nasdaq: TLPH), ("Talphera"), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced the first patient has been enrolled in the NEPHRO CRRT study. The NEPHRO CRRT registrational study will enroll 166 patients undergoing continuous renal replacement therapy (CRRT) at up to 14 clinical sites across the United States. The primary endpoint of the study is the mean post-filter activated clotting time for circuits infused with nafamostat versus placebo over the first 24 hours. "We are excited to be able to offer participation in this nafamostat study to our patients requiring CRRT," stated Stuart Goldstein, M.D., Professor of Pediatrics and Director of the Center for Acute Care Nephrology at Cincinnati Children's Hospital Medical Center. "Nafamostat, if approved following this trial, will be a valuable addition to our anticoagulant options for many patients." "We are pleased the first patient was enrolled in the study last week. Nafamostat has the potential to address disadvantages of the currently available U.S. products used for anticoagulation of the extracorporeal circuit. Enrolling the first patient in the NEPHRO study is the first of what we believe will be several important milestones for Talphera," stated Dr. Shakil Aslam, Chief Development Officer at Talphera. "Nafamostat has been used, and is a standard of care, in Japan and South Korea for over 30 years and we're excited about the prospects of making nafamostat available to healthcare providers in the United States, if approved," continued Dr. Aslam.

NEPHRO CRRT study patient screening has initiated at multiple clinical sites The safety and effectiveness of nafamostat is being assessed in the NEPHRO CRRT registrational study in 166 patients at up to 14 clinical sites Cash and investments at June 30, 2024 of $14.0 million Conference call and webcast to be held Wednesday, August 14, 2024 at 4:30 pm ET SAN MATEO, Calif., Aug. 14, 2024 /PRNewswire/ -- Talphera, Inc. (Nasdaq: TLPH), ("Talphera"), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced second quarter 2024 financial results and provided a corporate update. "We're excited to have initiated the screening of patients at multiple clinical sites in the NEPHRO CRRT registrational study. We now have finalized clinical trial agreement terms with eight large academic institutions including our potentially highest enrolling sites. We have also received FDA approval to increase the maximum number of study sites from 10 to 14 which we believe will help expedite completion of the study," stated Vince Angotti, CEO of Talphera. "The NEPHRO study should be enrolled and completed efficiently given the measurement of the primary endpoint is at 24 hours, with patients completing the study after 72 hours. In addition, having Breakthrough Device Designation from the FDA potentially provides an advantage for a timely approval of the product candidate next year. Nafamostat has the potential to address known disadvantages of currently available U.S. products for anticoagulation of the extracorporeal circuit and has been used, as a standard of care, in Japan and South Korea for over 30 years. We're looking forward to making nafamostat available to healthcare providers in the United States, if approved," continued Angotti. Dr. Shakil Aslam, Talphera's Chief Development Officer, has been leading the NEPHRO CRRT study since joining the Company. Dr. Aslam's expertise in nephrology and his 20 years of experience in academia and drug and device development has already proven to be an asset. Oversight of the NEPHRO study transitioned to Dr. Aslam from Dr. Palmer, Talphera's Chief Medical Officer, who, after nearly two decades in this role, will be retiring in October. Upon Dr. Palmer's retirement, Dr. Aslam will succeed her as Talphera's Chief Medical Officer and Dr. Palmer will continue as a consultant to the Company until completion of the NEPHRO study. "On behalf of the Board and the entire organization, I want to thank Pam for her leadership and dedication over her many years of service with the Company. We wish her all the best with her well-deserved retirement after co-founding Talphera and serving on the Board and as Chief Medical Officer for the last 19 years. Pam has been the scientific and medical force behind the Company, successfully achieving a U.S. drug approval and two European drug approvals. It has been a privilege to work with Dr. Palmer over the past seven years and I am grateful that Pam has agreed to remain as a consultant until the NEPHRO study has been completed. Additionally, we are delighted to have Dr. Aslam on board. Shakil is already making major contributions to Talphera, including expediting activities with the NEPHRO study," stated Vince Angotti. Second quarter 2024 and recent highlights Screening has been initiated at multiple clinical sites in the NEPHRO CRRT registrational study. The NEPHRO CRRT study will enroll 166 patients undergoing continuous renal replacement therapy (CRRT) at up to 14 clinical sites across the United States. The primary endpoint of the study is the mean post-filter activated clotting time for circuits infused with nafamostat compared against placebo over the first 24 hours. Clinical trial agreement terms with eight large academic institutions have been finalized with the final four site initiation visits of these initial eight institutions scheduled to be completed this month. Dr. Shakil Aslam joined Talphera effective May 20, 2024 as Chief Development Officer. Dr. Aslam has over 20 years of clinical and research experience across a broad therapeutic range including renal and vascular disease and acute kidney injury. He joined Talphera from BioCryst Pharmaceuticals where he was the Vice President, Clinical Development, Nephrology and Rare Diseases. Dr. Aslam previously held roles at Angion Biomedica, Fresenius Medical Care and Amgen and was an assistant professor at Georgetown University hospital for twelve years with a focus on acute and chronic kidney disease, hypertension, renal transplantation, and other nephrological diseases. Second Quarter 2024 Financial Information The cash, cash equivalents and investments balance was $14.0 million as of June 30, 2024. Combined R&D and SG&A expenses for the second quarter of 2024 totaled $4.3 million compared to $4.2 million for the second quarter of 2023. Excluding non-cash stock-based compensation expense, these amounts were $4.0 million for the second quarter of 2024, compared to $3.8 million for the second quarter of 2023. The increase in combined R&D and SG&A expenses in the second quarter of 2024 was primarily due to an increase in costs associated with Niyad development. For the second quarter of 2024, the Company recognized net loss from continuing operations of $3.8 million, as compared to net loss of $4.4 million for the second quarter of 2023, largely due to the change in fair value of the Company's warrant liability. The divestment of DSUVIA represents a discontinued operation; accordingly, all historical operating results for the business are reflected within discontinued operations. There were no DSUVIA related expenses in the second quarter of 2024. Net loss attributable to common shareholders for the second quarter of 2024 was $3.8 million, or $0.15 per basic and diluted share, compared to a net loss of $4.4 million, or $0.40 per basic and diluted share, for the second quarter of 2023.
