Name change to "Talphera" reflects a new era of the Company in partnership with the medical community developing novel solutions for medically supervised settings

SAN MATEO, Calif., Jan. 9, 2024 /PRNewswire/ -- AcelRx Pharmaceuticals, Inc. (Nasdaq: ACRX), (AcelRx), a specialty pharmaceutical company focused on the development and commercialization of innovative therapies for use in medically supervised settings, today announced the rebranding of the Company, with a name change to Talphera, Inc. ("Talphera"). The rebrand decision was made to reflect the Company's strategy of developing and commercializing products to support advancing care to optimize outcomes in medically supervised settings, moving beyond the original focus on acute pain. The Company's lead nafamostat product candidate, Niyad, is expected to have a Premarket Approval (PMA) submission to the FDA in the second half of 2024.

The name Talphera was derived from "Talisman", meaning a strong leader, and reflects the new "pharmaceutical era" for the Company. The company's new mission at Talphera is to support healthcare providers by developing and commercializing products in medically supervised settings that deliver advances in care to patients. Talphera will commence trading on the Nasdaq Global Market under the ticker symbol "TLPH" effective January 10, 2024.

"We were a company founded on acute pain treatments with the understanding that patient outcomes depend on the quality of the tools available to a patient's medical team. This understanding remains the focal point of our product candidates in development. Rebranding to Talphera represents a new era of the company where we have a broader mission to develop and commercialize innovative therapies for use in medically supervised settings beyond acute pain," said Vince Angotti, Chief Executive Officer of Talphera.

Talphera's lead product candidate, Niyad, has been granted FDA Breakthrough Designation and is currently being studied under an investigational device exemption, or IDE, as an anticoagulant for the extracorporeal circuit. If approved, Niyad would be the first-ever regional anticoagulant approved by the FDA for use in the dialysis circuit.

Talphera expects to initiate the registrational study of Niyad™, the NEPHRO CRRT (Nafamostat Efficacy in Phase 3 Registrational Continuous Renal Replacement Therapy) Study, shortly. The study has already received central Institutional Review Board (IRB) approval. The study is designed as a prospective, double-blinded trial to be conducted at up to 10 U.S. hospital intensive care units. The study will enroll and evaluate 166 adult patients undergoing renal replacement therapy, who cannot tolerate heparin or are at risk for bleeding. The primary endpoint of the study is mean post-filter activated clotting time using Niyad versus placebo over the first 24 hours. Key secondary endpoints include filter lifespan, number of filter changes over 72 hours, number of transfusions over 72 hours and dialysis efficacy (based on urea concentration) over the first 24 hours.

The first patient is expected to be enrolled for the NEPHRO study in the first quarter of 2024. Since the end of last year, the company has completed all sponsor actions and is awaiting activation from registered sites. A PMA submission for Niyad is expected to be filed with the FDA in the second half of 2024.
