About Orphan Drug Designation Orphan Drug Designation is granted by the U.S. FDA to investigational therapies addressing rare medical diseases or conditions that affect fewer than 200,000 people in the U.S. Orphan drug status provides benefits to drug developers, including assistance in the drug development process, tax credits for clinical costs, exemptions from certain U.S. FDA fees and seven years of post-approval marketing exclusivity. The orphan drug designation system in Japan aims to support the development of drugs for diseases that affect fewer than 50,000 patients in Japan, for which significant unmet medical need exists. An investigational therapy is eligible to qualify for ODD if there is no approved alternative treatment option or if there is high efficacy or safety compared to existing treatment options expected. Specific measures to support the development of orphan drugs include subsidies for research and development expenditures, prioritized consultation regarding clinical development, reduced consultation fees, tax incentives, priority review of applications, reduced application fees, and extended registration validity period. About Fast Track Designation Fast Track Designation is designed to facilitate the development and expedite the review of drugs to treat serious conditions and treat a serious or unmet medical need, enabling drugs to reach patients sooner. Clinical programs with Fast Track Designation may benefit from early and frequent communication with the FDA throughout the regulatory review process, and such clinical programs may be eligible to apply for Accelerated Approval and Priority Review if relevant criteria are met.

Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors, including: uncertainties associated with regulatory review of clinical trials and applications for marketing approvals; the availability or commercial potential of VYJUVEK or product candidates; the sufficiency of cash resources and need for additional financing; and such other important factors as are set forth under the caption “Risk Factors” in the Company’s annual and quarterly reports on file with the U.S. Securities and Exchange Commission. In addition, the forward-looking statements included in this press release represent the Company’s views as of the date of this press release. The Company anticipates that subsequent events and developments will cause its views to change. However, while the Company may elect to update these forward-looking statements at some point in the future, it specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing the Company’s views as of any date subsequent to the date of this press release. This press release also contains estimates and other statistical data made by independent parties and by the Company that involves a number of assumptions and limitations. Neither the Company nor any other person makes any representation as to the accuracy or completeness of such data or undertakes any obligation to update such data after the date of this press release. Non-GAAP Financial Measures This press release includes forward looking combined R&D and SG&A expense guidance that is not required by, or presented in accordance with, U.S. GAAP and should not be considered as an alternative to R&D and SG&A expense or any other performance measure derived in accordance with GAAP. The Company defines non-GAAP combined R&D and SG&A expense as GAAP combined R&D and SG&A expense excluding stock-based compensation. The Company cautions investors that amounts presented in accordance with its definition of non-GAAP combined R&D and SG&A expense may not be comparable to similar measures disclosed by competitors because not all companies calculate this non-GAAP financial measure in the same manner. The Company presents this non-GAAP financial measure because it considers this measure to be an important supplemental measure and believes it is frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in the Company’s industry. Management believes that investors’ understanding of the Company’s performance is enhanced by including this forward-looking non-GAAP financial measure as a reasonable basis for comparing the Company’s ongoing results of operations. Management uses this non-GAAP financial measure for planning purposes, including the preparation of the Company’s internal annual operating budget and financial projections; to evaluate the performance and effectiveness of the Company’s operational strategies; and to evaluate the Company’s capacity to expand its business. This non-GAAP financial measure has limitations as an analytical tool, and should not be considered in isolation, or as an alternative to, or a substitute for R&D and SG&A expense or other financial statement data presented in accordance with GAAP in the Company’s consolidated financial statements. The Company has not provided a quantitative reconciliation of forecasted non-GAAP combined R&D and SG&A expense to forecasted GAAP combined R&D and SG&A expense because the Company is unable, without making unreasonable efforts, to calculate the reconciling item, stock-based compensation expenses, with confidence. This item, which could materially affect the computation of forward-looking GAAP combined R&D and SG&A expense, is inherently uncertain.

Study designed to demonstrate impact of Alpha1-Proteinase Inhibitor Subcutaneous (Human) 15% (Alpha-1 15%), an alpha1 antitrypsin treatment, compared with Liquid Alpha1-Proteinase Inhibitor (Human) intravenousThis first in-human subcutaneous approach to treating alpha1-antitrypsin deficiency, if proven successful in clinical trials, could give patients the convenience and flexibility to administer their medication from home BARCELONA, Spain, Nov. 15, 2023 (GLOBE NEWSWIRE) -- Grifols (MCE: GRF, MCE: GRF.P NASDAQ: GRFS), one of the world’s leading producers of plasma-derived medicines, today announced that it has completed Cohort 1 of its Phase 1/2 study (NCT04722887) evaluating Alpha1-Proteinase Inhibitor Subcutaneous (Human) 15% (Alpha-1 15%), a subcutaneous (SC) alpha1 antitrypsin (AAT) treatment being compared to Liquid Alpha1-Proteinase Inhibitor (Human) intravenous (IV). Alpha1-antitrypsin deficiency (also known as alpha-1) is an underdiagnosed1 genetic disorder that occurs when a patient has low levels of AAT, a protective protein that safeguards the lungs. Augmentation therapy with IV AAT is the standard medical treatment option for patients with severe AAT deficiency and emphysema. If proven successful in clinical trials, a SC option could provide alpha-1 patients the ability to independently administer AAT therapy from home, allowing for greater convenience and flexibility. In this multi-center, single-dose and repeat-dose study over eight weeks, Cohort 1 has been completed and demonstrated no safety issues with Alpha-1 15% that would prevent the study from moving forward into Cohort 2. “A subcutaneous option would be a first for alpha-1 patients, providing more freedom when it comes to managing their AAT deficiency by allowing patients to administer their medication from the comfort of their own home. We are pleased to announce this milestone during Alpha-1 Awareness Month, contributing to raising further visibility about this rare disease,” said Jörg Schüttrumpf, Chief Scientific Innovation Officer, Grifols. “We look forward to moving this study into Cohort 2. Grifols has a strong commitment to the alpha-1 community and continues to innovate to find additional treatment options for patients living with this disease, in addition to more convenient alpha-1 testing alternatives such as AlphaID™ At Home, our recently launched direct-to-consumer genetic health risk service.” “During Alpha-1 Awareness month, we are excited to share this exciting news to the Alpha-1 community of a new clinical trial advancement in Alpha-1. We are thrilled that Grifols has completed Cohort 1 in clinical study of Alpha-1 15% and moving forward into Cohort 2. This study evaluating first-in-human subcutaneous dosing option for Alpha-1 patients could provide a new option that could easily be administered from their own homes,” said Scott Santarella, Alpha-1 Foundation President and CEO.
