A Two-center, Randomized, Double-blind, Placebo-controlled Study of Intravenous Plasma-purified Alpha-1 Antitrypsin for Hospitalized Patients With COPD Exacerbations (AECOPD Study)

Intravenous augmentation therapy with purified preparations of AAT (Alpha1-antitrypsin) derived from human plasma is a well consolidated specific therapeutic option to treat the severe deficient state of AAT. Prolastin is used to restore the balance between AAT and elastases in the lung and consequently to prevent a further deterioration in the pulmonary emphysema. Recently, in patients with COVID-19, without genetically lowered AAT levels with moderate to severe ARDS, treatment with AAT was demonstrated to be safe, feasible, and biochemically efficacious as an anti-inflammatory therapeutic therapy.
The aim of the study, based on biological plausibility, is to evaluate the safety and efficacy (from a biological perspective) of the administration of intravenous plasma-purified AAT as an anti-inflammatory treatment for patients admitted to hospital because of a COPD exacerbation leading to an acute or an acute on chronic respiratory failure.
Thirty-six adult patients hospitalized because of a COPD exacerbation leading to an acute or an acute on chronic respiratory failure will be enrolled by the two sites involved in the study, the Pneumology Unit of Fondazione IRCCS Policlinico San Matteo (Pavia, Italy) and the Pneumology Unit of IRCCS Istituto Clinico Humanitas, Rozzano (Milano, Italy).
Participants will be randomized 2:1 in the active treatment group (standard treatment + IV administration of Prolastin) or in the placebo group (standard treatment+ IV administration of 0.9% sodium chloride).
To address the clinical question from a biological perspective, we will investigate the decrease in inflammatory markers in the active treated group in comparison with the placebo group.
The primary objective is to demonstrate a significant reduction in systemic inflammation by IV Prolastin administered once at 120 mg per kilogram of body weight in patients with moderate to severe AECOPD, as assessed by the change in plasma concentration of IL6 at 7 days after randomization, in the active treatment group with respect to placebo group.
Secondary outcomes are:
1. Difference in change in plasma concentration of IL-1b, IL-5, IL-8, IL-10, and soluble TNF receptor 1 (sTNFR1), CRP at 7 days after randomization.
2. Differences in AAT antielastase activity, the amount of active elastase, the AAT levels in serum at baseline and at 7 days after randomization.
3. Difference in treatment failure rate. Treatment failure is a composite endpoint of need for either NIV or CPAP or need of ETI or need of transfer to ICU or in-hospital death after randomization
4. Impact of AECOPD on overall health, daily life, and perceived well-being in patients with obstructive airways disease by the change of St. George's Respiratory Questionnaire (SGRQ) score from Day 7 to follow-up (30 days after hospital discharge).
5. Differences in type and number of AEs and SAEs in the two groups
The expected duration of subject participation is from randomization to 30 days after hospital discharge, with a follow up phone contact.

The role of nitric oxide and connexin 43 in the cardioprotective effects of apigenin against doxorubicin-induced cardiotoxicity in male rats

Article

Author: Dehpour, Ahmad Reza ; Azizi, Yaser ; Goudarzi, Mina ; Safaei, Atlasi ; Fallah, Masoud ; Sheibani, Mohammad

BACKGROUND:

Doxorubicin (DOX) is one of the most widespread antibiotics used in the treatment of malignancies. Cardiotoxicity is the main side effect of DOX. Although the protective effects of apigenin have been shown, its mechanisms are still unknown. This study aimed to assess the role of nitric oxide (NO) in the protective effects of apigenin, particularly by altering the expression of connexin 43 (CX43) in the heart tissue.

METHODS AND RESULTS:

In this study, 60 male Wistar rats were divided into six equal groups: control (normal), DOX (2 mg/kg every 48 h for 12 days i.p.), apigenin (Api, 50 mg/kg oral administration), DOX + Api, DOX + L-NAME (Nitro-L-arginine methyl ester) (30 mg/kg i.p.), and DOX + Api + L-NAME. Our study assessed alterations in the heart weight and body weight, markers of cardiac function via echocardiography Ejection Fraction (%EF), Fractional Shortening (%FS), Left Ventricular Internal Diameter in Systole (LVIDs), and Left Ventricular Internal Diameter in Diastole (LVIDd), cardiac oxidative stress factors Superoxide Dismutase (SOD), Reduced Glutathione (GSH), Malondialdehyde (MDA), Catalase (CAT), cardiac injury markers Lactate Dehydrogenase (LDH), Creatine Kinase-MB (CK-MB), and Cardiac Troponin I (cTn-I), cardiac fibrosis, and CX43 expression (immunohistochemistry). Apigenin improved cardiac tissue damage and functional parameters such as left ventricular EF. Furthermore, treatment with apigenin, but not DOX, caused a significant reduction in the percentage of cardiac fibrosis and oxidative stress activity. Apigenin can also elevate the cardiac CX43 expression in the DOX + Api compared to the DOX group. NOS inhibition by L-NAME attenuates the protective effects of apigenin in DOX-induced cardiotoxicity COCCLUSION: Apigenin could exert its cardioprotective effects through an NO-dependent mechanism and elevation of CX43 expression.

Glycoengineered Recombinant Alpha1‐Antitrypsin Results in Comparable In Vitro and In Vivo Activities to Human Plasma‐Derived Protein

Article

ABSTRACT:

Alpha‐1‐antitrypsin (A1AT) is a multifunctional, clinically important, high‐value therapeutic glycoprotein that can be used for the treatment of many diseases, such as A1AT deficiency, diabetes, graft‐versus‐host disease, cystic fibrosis, and various viral infections. Currently, the only U.S. food and drug administration‐approved treatment for A1AT disorders is intravenous augmentation therapy with human plasma‐derived A1AT (pdA1AT). In addition to its limited supply, this approach poses a risk of infection transmission, since it uses therapeutic A1AT harvested from donors. To address these issues, we sought to generate recombinant human A1AT (rhA1AT) that is comparable to its plasma‐derived counterpart using glycoengineered Chinese Hamster Ovary (geCHO‐L) cells. By perturbing nine key genes that are part of the CHO glycosylation machinery and expressing the human ST6GAL1 and A1AT genes, we obtained stable, high producing geCHO‐L lines that produced rhA1AT having a highly similar glycoprofile to pdA1AT. Additionally, the rhA1AT demonstrated in vitro activity and in vivo half‐life comparable to commercial pdA1AT. Thus, we anticipate that this platform will help produce human‐like recombinant plasma proteins, thereby providing a more sustainable and reliable source of therapeutics that are cost‐effective and better‐controlled regarding purity, clinical safety, and quality.

Apigenin restores macrophage homeostasis and angiogenesis via Fgr/IL10 axis in recurrent spontaneous abortion

Article

Author: Li, Ming-Qing ; Li, Meng-Ying ; Yang, Yi-Xing ; Liu, Song-Ping ; Liu, Nan ; Cao, Xiao-Yan ; Chen, Si-Man ; Xie, Feng ; Huang, Xu

Recurrent spontaneous abortion (RSA) is closely associated with disruption of both immune homeostasis and vascular development at the maternal-fetal interface. To decode the underlying cellular defects, we performed single-cell RNA sequencing (scRNA-seq) on human decidual tissues, revealing a profound imbalance in macrophage polarization and impaired efferocytosis in RSA patients. Through transcriptomic screening and clinical validation, we pinpointed the Fgr proto-oncogene, Src family tyrosine kinase (Fgr) as a key pathological driver overexpressed in RSA macrophages, acting as a molecular brake on the pro-healing M2 phenotype. Seeking a targeted intervention, we demonstrated that the natural flavonoid Apigenin (Api) directly binds and inhibits the Fgr kinase domain, which essentially triggers robust Interleukin 10 (IL10) secretion. Crucially, this Api-mediated Fgr/IL10 signaling axis not only restores M2 polarization and enhances apoptotic cell clearance, but also rescues pro-angiogenic crosstalk with endothelial cells in a vascular endothelial growth factor (VEGF) -dependent manner. Furthermore, in a lipopolysaccharide (LPS)-induced murine miscarriage model, Api administration effectively reduced embryo resorption and rescued pregnancy loss. Collectively, our study highlights the Fgr/IL10 axis as a critical determinant of decidual homeostasis and establishes Api as a promising therapeutic strategy for RSA.

Grifols Announces Last Patient Last Visit in SPARTA, its Phase 3 Outcomes Study of Prolastin®-C in Patients With Emphysema Due to Alpha-1 Antitrypsin Deficiency

Grifols’ SPARTA phase 3 trial is designed to evaluate the clinical efficacy and safety of two separate weekly dose regimens of Grifols’ Prolastin ®-C (Alpha1-Proteinase Inhibitor [Human] modified process) in patients with emphysema due to alpha-1 antitrypsin (AAT) deficiency (known as alpha-1) The trial is the largest randomized, double-blind, placebo-controlled study on alpha-1 and augmentation therapy to-date and has the potential to provide clinical evidence on slowing progression of lung tissue loss in this patient group This milestone marks the completion of follow-up for all 345 participants enrolled across 37 sites in 16 countries Top line results expected by the end of 2026 Grifols continues to advance scientific innovation in alpha-1 through a comprehensive approach that includes disease awareness, genetic testing, clinical research and treatment Aug. 10, 2026 -- Grifols (MCE:GRF, MCE:GRF.P, NASDAQ:GRFS), a global healthcare company and leading producer of plasma-derived medicines, today announced the completion of the clinical portion of SPARTA (Study of ProlAstin-C Randomized Therapy with Alpha-1 augmentation; NCT01983241), its phase 3 outcomes study evaluating the clinical efficacy and safety of two dose regimens of Prolastin®-C (Alpha1-Proteinase Inhibitor [Human] modified process) in patients with emphysema associated with alpha-1 antitrypsin deficiency (AATD), also known as alpha-1. The last patient in the trial completed their final study visit last week. This milestone, known as “last patient, last visit” (LPLV) signifies completion of follow-up for all 345 enrolled participants. Topline results are expected by the end of this year. Alpha-1 is a genetic disorder that can result in chronic obstructive pulmonary disease (COPD), a group of respiratory diseases that include emphysema, which can occur when a patient has low levels of AAT, a protective protein that safeguards the lungs. Alpha-1 remains significantly underdiagnosed1 worldwide despite being the most common known genetic risk factor for COPD.】】 SPARTA is the largest randomized, double-blind, placebo-controlled study conducted to date in augmentation therapy for alpha-1 patients with emphysema. The trial was designed to evaluate the efficacy and safety of weekly administration of two active dose levels of Prolastin-C (60 mg/kg and 120 mg/kg) compared with placebo over a three-year treatment period. The study was conducted across 37 clinical sites in 16 countries and used whole-lung computed tomography (CT) densitometry as its primary efficacy endpoint. CT densitometry is considered the most sensitive method for detecting emphysema progression and quantifying lung tissue loss in patients with AATD2, making SPARTA the first and only three-year study in AATD to generate longitudinal clinical evidence using this biomarker. “The completion of patient follow-up in SPARTA marks a significant milestone for Grifols and the alpha-1 community,” said Eduardo Herrero, Grifols’ Executive Vice President Biopharma Industrial and Scientific Innovation. “We are deeply grateful to the patients, investigators and study teams whose dedication made this achievement possible. As the first and only prospective, double-blind, placebo-controlled three-year CT densitometry study in alpha-1-related emphysema, SPARTA reflects our long-standing commitment to people living with alpha-1 through innovation in testing, diagnosis and treatment.” In addition to the SPARTA study, Grifols recently began the SWIFT-SC trial (NCT07555483), the first Phase 3 trial evaluating a weekly subcutaneous alpha1-proteinase inhibitor for the treatment of AATD. These clinical trials demonstrate the company’s ongoing commitment to innovation and to improving therapeutic options and long-term outcomes for patients with alpha-1. Alpha-1-antitrypsin deficiency, also known as alpha-1, is a rarely diagnosed genetic disease that can result in chronic obstructive pulmonary disease (COPD), a group of respiratory diseases that includes emphysema, a lung condition that causes shortness of breath. Patients who have alpha-1 have a genetic deficiency of alpha-1 antitrypsin, a protective plasma protein that safeguards the lungs from inflammation caused by infection and inhaled irritants such as tobacco smoke. Alpha-1 is the major known genetic risk factor for COPD3. PROLASTIN®-C is an alpha1-proteinase inhibitor (human) (alpha1-PI) indicated for chronic augmentation and maintenance therapy in adults with clinical evidence of emphysema due to severe hereditary deficiency of alpha1-PI (alpha-1-antitrypsin deficiency). The effect of augmentation therapy with any alpha1-PI, including PROLASTIN-C LIQUID, on pulmonary exacerbations and on the progression of emphysema in alpha1-PI deficiency has not been conclusively demonstrated in randomized, controlled clinical trials Clinical data demonstrating the long-term effects of chronic augmentation or maintenance therapy with PROLASTIN-C LIQUID are not available PROLASTIN-C LIQUID is not indicated as therapy for lung disease in patients in whom severe alpha1-PI deficiency has not been established PROLASTIN-C is contraindicated in immunoglobulin A (IgA)-deficient patients with antibodies against IgA or patients with a history of anaphylaxis or other severe systemic reaction to alpha1-PI products. Hypersensitivity reactions, including anaphylaxis, may occur. Monitor vital signs and observe the patient carefully throughout the infusion. If hypersensitivity symptoms occur, promptly stop PROLASTIN-C infusion and begin appropriate therapy. Because PROLASTIN-C is made from human plasma, it may carry a risk of transmitting infectious agents, e.g., viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. This also applies to unknown or emerging viruses and other pathogens. The most common adverse reaction during clinical trials in > 5% of subjects was upper respiratory tract infection. The most serious adverse reaction observed during clinical trials with PROLASTIN-C was an abdominal and extremity rash in 1 subject. for Prolastin-C.

Grifols doses first participant in Phase 3 study evaluating novel subcutaneous therapy for alpha1-antitrypsin deficiency

First-of-its-kind Phase 3 study to evaluate weekly subcutaneous Alpha1-Proteinase Inhibitor, a novel approach, compared to standard intravenous therapy SWIFT-SC is an open-label, multicenter, randomized trial Positive outcome could expand treatment flexibility for patients Barcelona, Spain, June 29, 2026 – Grifols (MCE:GRF, MCE:GRF.P, NASDAQ:GRFS), a global healthcare company and leading producer of plasma-derived medicines, today announced the enrollment of the first patient in its Phase 3 SWIFT-SC clinical trial, a global study designed to evaluate a novel subcutaneous (SC) formulation of Alpha1-Proteinase Inhibitor (Alpha1-PI) for the treatment of alpha1-antitrypsin (AAT) deficiency. The SWIFT-SC study (NCT07555483) “An Open-Label, Multicenter, Randomized, Non-Inferiority Pharmacokinetic and Safety/Tolerability Study of Two Different Weekly Doses of Alpha1-Proteinase Inhibitor Subcutaneous (Human) 15% in Patients With Alpha1-Antitrypsin Deficiency Compared to Corresponding Standard 60 mg/kg/Week and 120 mg/kg/Week Doses of Intravenous Alpha1-Proteinase Inhibitor (5%)” will compare two different weekly doses of subcutaneous Alpha-15% with corresponding standard intravenous Alpha1-PI doses. The trial’s short name, SWIFT-SC, stands for Subcutaneous; Weekly dosing; Alpha1 proteinase Inhibitor Formulation-focused; clinical Trial – subcutaneous (SC), representing the aim of the study. The purpose of SWIFT-SC is to determine whether the subcutaneous formulation demonstrates non-inferior pharmacokinetics compared to intravenous therapy, while also evaluating safety and tolerability. Adult participants with AAT deficiency will be randomly assigned to two treatment groups in this open-label study. Advancing toward more flexible treatment options SWIFT-SC is the first Phase 3 clinical trial to evaluate subcutaneous augmentation therapy in patients with AAT deficiency. This trial builds on the successful completion of the Phase 1/2 study, NCT04722887, sponsored by Grifols. The investigational therapy uses a 15% concentration, approximately three times higher than the standard intravenous formulation, enabling delivery via subcutaneous administration. Subcutaneous administration of medicines may provide meaningful benefits for patients by enabling self-administration outside of clinical settings, reducing reliance on infusion centers or home healthcare visits, and providing greater flexibility in when and where treatment is administered. “Advancing treatment approaches is an important step forward for patients living with alpha1-antitrypsin deficiency,” said Eduardo Herrero, Grifols’ EVP Biopharma Industrial and Scientific Innovation. “With SWIFT-SC, we are exploring the potential to expand treatment options to deliver Alpha1-PI therapy in a way that best aligns with individual patient preferences.” Building on ongoing Alpha-1 research SWIFT-SC complements Grifols’ broader clinical program in AAT deficiency, including the ongoing SPARTA study (NCT01983241), which is the largest prospective, randomized, double-blind, placebo-controlled study to date designed to provide computed tomography (CT) densitometry efficacy data on the impact of plasma-derived augmentation therapy for AAT deficiency. SPARTA is expected to complete in the second half of this year, with top-line results anticipated by year-end. Together, these studies reflect Grifols’ commitment to advancing innovative therapeutic options and improving long-term outcomes for patients with AAT deficiency.
